Paint and varnish coatings should:

it is firmly held on the surface;

have the necessary mechanical strength, troopiness and elasticity;

have resistance against the impact of moisture, petroleum products, exhaust gases and sun rays;

be water and gasproof;

maintain their qualities at positive temperatures in the summer of negative temperatures in winter;

be neutral, not cause corrosion of painted surfaces;

quickly dry after applying to the surface and do not require complex drying devices for this;

provide the necessary color of the painted surface with minimal thickness and the number of layers applied, i.e. have good covers;

being inexpensive, durable and allow to produce partial or complete restoration of inexpensive and affordable ways.

Not one of the modern materials does not fully meet the specified requirements. According to this and a number of other reasons, in most cases, coatings are made multi-layered.

10.2 Structure of paint and varnish and requirements for basic materials

The main elements of the structure of the multi-layer paint coating are: a layer of soil, a layer of twinweight and several layers of paint (Figure 10.1).

The first coating layer is applied to the prepared surface - ground. Its main purpose is to provide high adhesion between metal and subsequent coating layers.

Based on this, the soils are required:

high adhesion (adhesion) to metals, wood and other structural materials;

the ability to maintain subsequent coating layers due to the interpenetration of materials;

good anti-corrosion properties;

if possible, rapid drying.

1 - stained surface;

2 - a layer of soil;

3 - layer of local putty;

4 - a layer of common putty;

5 - a layer of paint.

Figure 10.1 - the structure of a multilayer paint coating

Puttlevka is used to align the surface in the surface. There are local and general sweep layers. The first intends to align large defects, the second is to obtain a smooth coating throughout the area of \u200b\u200bthe area.

Sweattte materials required:

• good adhesion to soil;

  sufficient mechanical strength, especially impaired and vibration resistance;

  relatively good dryness;

  ability to grind.

The processed spatlet or primer is covered with several layers of paint. Each layer passes the stage of drying.

From the paints required:

sufficient adhesion to soils and spatles;

the ability to form a solid protective film;

high weather resistance;

resistance to the effects of technical fluids and other substances with which the coating is in contact with the operation of the machines.

10.3 Classification of paints and varnishes

Paintwork materials are indicated by five groups of characters.

The first group of signs determines the type of paintwork material and is denoted by a full word, for example, "primer", "spiteling", "enamel", "lacquer".

The second group of signs determines the main resin that is part of the film-forming substance, and is denoted by two letters: GF - glyftali, PF - pentaftali, FL - phenolic, ml - melamine, EP - epoxy, VL - polyvinyl acetate, NC - Nitrocellulose, Ma and vegetable oil and etc.

The third group of signs determines the group to which the paintwork material is assigned to its purpose: 0 - primers and varnishes semi-finished, 00 - Plocks, 1 - Weather-resistant, 2 - resistant indoors, 5 - special (for skin, rubber, etc. ), 7 - resistant to various media, 8 - heat-resistant, 9 - electrical insulating. Between the second and third groups of signs is rated.

The fourth group of signs relates mainly to enamels and defines their color. Dimensional words ("white", "blue", and if there are shades "Blue - 1", "Blue - 2", etc.). If the enamel color is assigned a number, then in the fifth group of characters, the color number first is indicated, and then writes the color completely words. There is a dash between the fourth and fifth groups of signs.

An example of a conditional notation: "Enamel ml - 12 - 38 blue" (enamel, basic film-forming resin methylinic (ml), weather resin (1), sequence number of the second (2), color blue (38).

Paint coatings are classified according to the coating material, the appearance of the surface of the coating (coating class) and by operating conditions.

According to the appearance of the surface of paints and varnish coatings are divided into four classes. The first class is characterized by a smooth, monophonic surface, without defects visible to a naked eye (car bodies). The second class allows on the surface of individual minority defects: sorts, strokes, trail of stripping, etc. (buses, cabins, and the plumage of trucks). The third class allows irregularities associated with the condition of the surface to be painted to its color. The fourth grade admits visible defects that do not affect the protective properties of the coating. According to the third and fourth grade, frames, axes, wheels, cargo platforms and other parts of the machines that need only in anti-corrosive protection are stained.

Under the conditions of operation (stability), paintwork coatings are divided into eight groups: resistant indoors (P); Weather-resistant (a) (car coatings); chemically resistant (x, hk, housing); waterproof in fresh (c) and sea water (VM); heat-resistant (T); oil resistant (m); Gas-resistant (b) and electrical insulating (E).

According to the degrees of gloss, paints and varnish coatings are divided into glossy, semi-convened and matte.

An example of the conventional designation of the paintwork; "UM NTS - 25, Blue, I. P" (The coating is applied to nitroemal (NTS) of blue, performed according to the first class (I) and resistant during the operation indoors (P).

The most important indicators of varnishes and paints include: viscosity, bottling (the ability of paints to give a smooth, smooth surface, without strokes from the brush and without ripples when applied by a pulverizer), drying time, covering (paint property when applied to a thin uniform layer to make an invisible color to the painted Surfaces), adhesion (the ability of paint film sticking to the painted surface), strength and hardness of film, water and oil-resistance, toxicity and flavors.

1. This standard applies to paintwork covers (hereinafter referred to as coatings) of industrial products and establishes general technical requirements for selecting coatings on decorative properties.

2. Under the decorative properties understand the properties of the coating, providing its aesthetic perception.

The decorative properties of the coating are characterized by color, glitter, texture and class according to GOST 9.032-74 *.

3. The choice of coating on decorative properties is carried out at the design stage in the process of artistic design of products.

4a. Designed in the process of artistic design, finishing options are recorded in the map of the color factor solution of the finishing of the product.

(Introduced additionally, meas. No. 1).

Types of harmonious color combinations

1. Using the color of paintwork coatings to create the appropriate color solutions of products is determined by the psychological (emotional) and physiological effect on the person of individual colors and color combinations.

When choosing the color combinations of coatings, their harmony must be the first and main condition.

2. To obtain harmonious combinations of colors, it is necessary that there is a certain relationship between colors (contrast or similarity between colors in color tone, light or saturation).

3. The relationship between flowers is achieved using the principles of choosing color combinations in a color circle (damn 1).

Color circle

Well - yellow; Jo - yellow-orange; O - orange; Ko - red-orange; K - red; P - purple; FP - purple-purple; F - purple; C - blue; SZ - blue-green; Z - green; Zhz - yellow-green; I, II, W, IV - Color Zones

Heck. one

4. When choosing color combinations, the characteristics of four psychological optimal primary colors are taken into account - yellow (221), red (7), blue (427), green (324) and intermediate - orange, purple-purple, yellow-green.

5. Color combinations are divided into five major groups on psychophysiological characteristics: contrasting, related, relative-contrast, equitonal, complex.

9. The car is operated in atmospheric conditions of moderate and tropical climate, contaminated by road dust, mud and exposed to a periodic washing of hot and cold water with brushes. Interremant dates are 3 years, car care is permanent.

10. The specified operating conditions are satisfied with paintwork coatings obtained on the basis of melamino-alkyd enamel ML-12, perchlorvinyl enamel of the HC-110.

The coating system consisting of two layers of enamel ML-12, applied to the primed surface, resistant under atmospheric conditions of moderate and tropical climate for 3 years.

The coating system consisting of two HP-110 enamels, applied to phosphated and primed surface, is also resistant under conditions of moderate and tropical climates for 3 years.

11. The color, texture, brilliance and enamel class ML-12 and the HC-110 meet the requirements: enamel color ML-12 orange (121, 128), H-110 enamel yellow (285, 286), coatings according to recommended - smooth , glossy (ml-12), semi-conjunctive (HPF-110), the maximum achieved class of coating II for enamel ML-12 and III for enamel of the HC-110.

12. Considering the level of production of the painting area (production - serial, staining on the streaming conveyors by the method of pneumatic spraying or spraying in the electric field, drying in thermoadiating drying chambers at a temperature of 130 ºС), the enamel ML-12 should be selected, which is applied by the specified method and has mode Thermoradiation drying at a temperature of 130 ºС for 20 minutes.

Appendix 5 reference

Types of harmonious color combinations

1. Using the color of paintwork coatings to create the appropriate color solutions of products is determined by the psychological (emotional) and physiological effect on the person of individual colors and color combinations.

When choosing the color combinations of coatings, their harmony must be the first and main condition.

2. To obtain harmonious combinations of colors, it is necessary that there is a certain relationship between colors (contrast or similarity between colors in color tone, light or saturation).

3. The relationship between flowers is achieved using the principles of choosing color combinations in a color circle (damn 1).

Color circle

Yellow; Jo - yellow-orange; O - orange; Ko - red-orange; Red; Pt- purple; FP - purple-purple; F - purple; C - blue; SZ - blue-green; 3 - green; Zhz - yellow-green; I, II, III,

IV- Color zones

4. When choosing color combinations, the characteristics of four psychological optimal primary colors are taken into account - yellow (221), red (7), blue (427), green (324) and intermediate - orange, purple-purple, yellow-green.

5. Color combinations are divided into five major groups on psychophysiological characteristics: contrasting, related, relative-contrast, equitonal, complex.

6. Contrast combinations are characterized by the use of colors having significant differences in color tone, saturation and lightness.

Contrast combinations are the most vivid and active in perception.

To enhance contrast, the sizes and configuration of the surface of the coating of different colors are taken into account, their mutual location.

6.1. Contrast colors in color tone should be on the opposite sides of the color circle (damn 2). In combination, these colors with the same saturation and light values \u200b\u200bmust enhance each other's saturation and perceived brighter.

6.2. Contrast colors in lightness should differ significantly with the same color tone and saturation.

6.3. Contrast colors in saturation should differ significantly with the same color tone and lightness.

7. Related combinations are characterized by the use of colors located in a color circle within two main adjacent colors and contains their shades (features 3). There are four types of related combinations: yellow-red, red-blue, blue-green, green-yellow.

Schemes of combinations of related colors

Related combinations are soft, few active, static perception.

8. The animated-contrast combinations are characterized by the use of colors located in a color circle in the adjacent sectors and containing shades of one primary color and two adjacent main colors (damn 4). There are four kinds of relative-contrast combinations: green-yellow-red, yellow-red-blue, red-blue-green, blue-green-yellow.

Schemes of related and contrasting combinations of colors

The animated-contrast colors are active, dynamic by perception.

9. Equivalent combinations are characterized by the use of colors of one color tone at one saturation, but different lightness; with one lightness, but of different saturation; With different lightness and saturation.

10. Complex combinations are characterized by the use of chromatic colors with achromatic. Achromatic colors are well consistent with chromatic colors with different and with equal

light.

11. Choosing harmonious color combinations for PP products. 6-10 take into account: the correspondence of colors and their combinations of functional purpose and the conditions of operation of the product, the volume and spatial structure, tectonics, dimensions and plastic of the external form of the product; Requirements of information and safety of labor; Fashion color preferences; color and graphic scheme of the appearance of the product; The characteristics of the texture and gloss enamel of the selected colors and the quality of the coating.

Annex 6 Reference

An example of selection of coatings on decorative properties

1. Choosing a paint material for finishing the cabin of a truck model

2. For decorative properties, the coating must correspond to the functional purpose and operating conditions of the car.

3. The color of the car's cabin should be contrasting to the color of the environment (color, greens, etc.). The cabin should be bright or bright. The reflection of light from the paint coating of the cabin (especially the roofs) should be high (at least 60%) so that the cabin is minimally heated from the sun's rays.

4. To ensure favorable operating conditions of the driver, the color of the cab should not be dark, and the surface of the mirror-glossy. For quick removal of dirt, the texture must be smooth.

5. Volumetable-spatial structure, tectonics, dimensions, plastic of the outer shape of the designed cabin require its single color painting with enamels of light or bright colors. The color should be pure, unpolluted, bright, expressing the power of a car that does not cause negative emotions and unpleasant associations.

6. To create a color manifold on the streets of cities, on the roads, construction sites, etc. Color must be among the colors, mutually complementing each other in the system of the color gamut of road vehicles, construction and road machines.

7. Enamel of the selected color should be produced.

8. Requirements of PP. 2-7 correspond, for example, orange (121, 128) and yellow (285, 286) colors. Class III Class in accordance with Appendix 1.

9. The car is operated in atmospheric conditions of moderate and tropical climate, contaminated by road dust, mud and exposed to a periodic washing of hot and cold water with brushes. Interremant dates are 3 years, car care is permanent.

10. The specified operating conditions are satisfied with paintwork coatings obtained on the basis of melamino-alkyd enamel ML-12, perchlorvinyl enamel of the HC-110.

The coating system consisting of two layers of enamel ML-12, applied to the primed surface, resistant under atmospheric conditions of moderate and tropical climate for 3 years.

The coating system consisting of two HP-110 enamels, applied to phosphated and primed surface, is also resistant under conditions of moderate and tropical climates for 3 years.

11. In color, texture, brilliance and class enamel ML-12 and the HC-110 meet the requirements: Enamel ML-12 orange color (121, 128), H-110 enamel yellow (285, 286), coatings according to the recommended Annex 2 - Smooth, glossy (ml-12), semi-adhesive (HC-110), the maximum achieved class of coating II for enamel ML-12 and III for enamel of the HC-110.

12. Considering the level of production of the painting area (production - serial, staining on the stream conveyors by the method of pneumatic spraying or spraying in the electric field, drying in thermal drying chambers at a temperature of 130 ° C), the enamel ML-12 should be selected, which is applied by the specified method and has Thermoradiation drying mode at a temperature of 130 ° C for 20 minutes.

Emale HP-110 is applied by a pneumatic spraying method and has a drying mode at a temperature of 18-23 ° C for 3 hours or at a temperature of 60 ° C for 1 hour.

Thus, it should use enamel ML-12 for GOST 9754-76 orange (121, 128) for staining the designed model of the MAZ truck.

It is allowed in the designation of the coating instead of the paintwork material of the outer coating layer to record the designation of paintwork materials in the technological sequence of application (primer, putty, etc.) indicating the number of layers or designate the coating in accordance with standards or specifications.
(Modified edition, change No. 3). 3.3. The designation of the paintwork material, the coating class and the designation of the operating conditions is separated by points. When exposed to various operating conditions, their designation is divided by the "dash" sign. Examples of the designation of coatings are given in Table. 3.

Table 3.

Designation of coating	Characteristics of the coating
Enamel ML-152 blue. II.U1.	Blue enamel ML-152 coating in class II, operated in the open air of a moderate macro-climatic area
Enamel xs-710 gray. Luck XC-76.IV.7 / 2	The coating of the HS-710 gray enamel with the subsequent varnish lacquer x-76 by IV class, operating when exposed to solutions of acids
H-124 blue enamel. V.7 / 1-T2	The coating of the Blue Emal CH-124 according to V class, operating under a canopy in the atmosphere, contaminated with gas and other industries, in a tropical dry macroclimatic area
Primer FL-03K brown. Vi.U.	Coatings of primer FL-03K according to the VI class, operated in a closed room with natural ventilation without artificially adjustable climatic conditions in the conditions of a temperate macroclimatic area
Enamel PF-115 Dark gray 896.III.U1	Covering dark gray 896 PF-115 enamel in III class, operated in the open air of a moderate macroclimatic area

(Modified edition, change. No. 3.4).

3.4. In the designation of the coatings, it is allowed to indicate special conditions of operation of the full name.

3.5. If the painted surface is simultaneously or alternately located in various operating conditions, then they are all specified in the designation. At the same time, the main condition for exploitation is in the first place.

3.6. If the paintwork is preceded by a metal or non-metallic inorganic coating, then their designations are separated by a fraction, and the designation of the paint coating is put on the second place. For example, a cadmium coating, a thickness of 6 μm, followed by the staining of the red-brown polyvinyl butio enamel of VL-515 in the III class, for the operation of the coating when exposed to petroleum products:

KD6 / Enamel VL-515 Red-Brown.III.6 / 2

Requirements for painted metal surfaces

Notes:
1. The sign "-" denotes that the use of coatings for this class is unacceptable or economically inappropriate.
2. For all classes of coatings are not allowed, unevenly cropped edges, sharp edges and angles in the transition places from one cross section to another.
3. When dyeing cast parts, more than 10 tons are allowed to increase non-1 mm for III-VI classes.
4. It is allowed for products with a stained surface of more than 5 increasing non-plane by 2.5 mm for III class, by 3.5 mm for IV-VI classes.
5. When dyeing cast parts, weighing more than 5 tons for III and IV classes is allowed to increase the surface roughness to be putty to 630 microns.
6. Only local spatlement is allowed to cover the first class.
7. Under the individual surface irregularities, they understand irregularities with dimensions (length or width) not more than 20 mm.
8 Requirements for non-plane surface are given for flat surfaces with the greatest size of more than 500 mm. When evaluating not flatness of the surface, individual irregularities are not taken into account
9. For surfaces subjected to spatlement, under the coatings of the III of the class are allowed to have separate irregularities with a height of up to 1 mm.

Score assessment by profilograph-profilometer

Higure estimation by a profilograph-profilometer of the surface of the coating is carried out in accordance with the instructions for the device at the maximum length of the transit of the sensor 40 mm. The recommended vertical increase when recording is 2000-4000 times, horizontal - 4 times.
Shagreen is characterized by H high and base T irregularities. According to the profilogram, the average height and average base in millimeters for five maximum protrusions are determined: Where - height of irregularities at five points; Where is the basis of irregularities in five points.
Accuracy Assessment is given in the table.
