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 that exhaust gases and sun ray;
Be water and gasproof;
Keep your qualities at positive temperatures in summer 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 when minimum 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 modern materials It 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;

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.
Example legend: "Enamel ml - 12 - 38 blue" (enamel, basic film-forming resin methylinic (ml), weather-resistant (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 the naked eye (body passenger cars). 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 (B) 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; "EM NC - 25, Blue, I. P" (coating applied to nitroemal (NTS) of blue color, Completed according to the first class (i) and resistant during the operation of indoors (P).
To the most an important indicators Nakov and paints include: viscosity, bottling (the ability of paints to give a flat, smooth surface, without strokes from the brush and without ripples when applied by a pulverizer), drying time, hide (paint property when applied to a thin uniform layer to make an invisible surface color), adhesion (The ability of paint film sticks to the painted surface), strength and hardness of film, water and oil-resistance, toxicity and flavors.
10.4 Technology Coloring car bodies. Auxiliary materials
Technology Coloring car bodyworks on automobiles, as a rule, includes the following main operations: degreasing; phosphating; primary priming and drying; applying secondary primer or twin and drying; Application of enamel of a certain color and drying.
The painting of engine parts, chassis and transmissions is usually produced in one layer along the skim and phosphatic surface.
Auxiliary materials are designed to prepare the surface in front of the color, breeding paintwork materials to a working viscosity, accelerating the drying of the coating.
Solvents are used to clean surfaces before coloring, as well as solvents apply to working viscosity. As solvents are used different organic compounds And in some cases water. Organic solvents are single-component or multicomponent (mixtures of single-component solvents), called compound solvents, diluents or discharge. The most common single-component solvents and their purpose are shown in Table B.1 of Appendix B. Composition and purpose of multicomponent solvents are shown in Table B.2 Appendix B. Using solvents Motion is made - special compositions designed to remove old paint coatings. Washings contain the following components: active solvents, thickeners, evaporation moderators, baking powers, emulsifiers, corrosion inhibitors and special additives. The composition and purpose of spokes of paintwork are shown in Table B.3 Appendices B.
Degreasing the surface in front of the color is to remove from the surface of conservative and technological oils, lubricants, grinding and pollution compounds, various contaminants. Organic solvents, alkaline or acidic water solvents are used for degreasing detergent, Emulsion formulations (Tables B.4 and B.5, Appendix B). Requirement Degreasing is achieved by a combination of various means of degreasing in the same technology. Degreasing car body bodies, as a rule, begins with pre-training: The outer surfaces are wiping with a brush or white-spirited winds, and places having a light rust rack, dioxidin - a special deoxidating fluid. A more progressive method of preliminary preparation of the surface of the bodies in front of the color is the jet washing with an aqueous solution of the composition "Omega - 1", which has detergent and deoxidizing action.
Phosphating of the metal surface in front of the color allows us to provide the necessary level of protective properties of paint coatings - increases the adhesion of the coating to the metal and significantly slows down the development of the underfloor corrosion. Phosphating produce surface treatment aqueous solutionscontaining phosphate salts of metals and various additives that play the role of activators of the process of phosphating, corrosion inhibitors, thickeners and fillers. For phosphating, solutions based on zinc salts, iron, manganese, as well as their mixtures (Table B.6, Appendix B) are used. The surface treatment with phosphating solution in the factory conditions is made with dipping or spraying. In the repair technology also applies the obulation and brush or tampon.
Grinding and polishing operations are part of technological process Coloring car bodies. Before the flow of car bodies, there is grinding of external surfaces to eliminate metal defects and ensure roughness of no more than 2 microns. In the technology of coloring body grinding, grinding is used to improve adhesion between separate layers of coating, smoothing the layers of spitels, as well as eliminating defects - influx, irregularities, fattened layers of paint and varnish coatings. For grinding, abrasive materials are used in the form of powders, pastes, grinding skins on a paper and tissue basis. There is dry and wet (with water) grinding methods. More common wet fashionFor which waterproof grinding skins are used.
10.5 Chemicals for car care
By destination chemicals To care for the car, divided into the following types: detergents, cleaning, polishing, protective, sealing, operational, auxiliary.
10.5.1 Detergents
The difficulty of removing the removal from the surface of the car pollution can be conditionally divided into three types: weakly coupled (sand with clay impurities), medium-dimensional (sand with clay impurities, as well as with impurities of organic and oil substances) and firmly related (asphalt particles, various resinous contaminants). Weakly coupled pollution can be washed with water, medium-sized and strength contaminants are removed using one water.
For washing paintworks, as well as upholstery and plastic parts of the car, an autosampuna is used, which includes surface active substances, alcohols, carboxylomethylcellulose, liquid sodium glass and other substances. The recipes of the car sucks are selected in such a way that they do not have a corrosion action. There are car supersampou, the use of which contributes to anti-corrosion protection, they are especially recommended for washing a damaged paint and varnish coating.
Exist detergents for washing and short-term conservation of paintwork coatings (varnish wedge).
A high efficiency is the auto-ready-making of the thresholds type, intended for washing the closed cavities and the bottom of the body before anti-corrosion processing.
10.5.2 Cleaners
For the cleaning different parts and car units from contaminants that are not removed using shampoos (rust, naigne and other strength connections) are used special cleaning products.
To remove bitumen, fat and oil spots with paint surfaces of the car, liquid preparations of the "Choy cleaner of bitumen spots" containing highly efficient solvents are very effective.
To remove rust chemical method From metal surfaces before applying anticorrosers, paste-like rust cleaners type "Omega - 1" are used.
For rapid removal of dirt, oils and other water insoluble pollution from the surface of the engine and the units, effective liquid drugs like "engine-chipper". It is applied to the cleaning surface and after 10 - 15 minutes are washed with water until the resulting emulsion has been removed. It is not allowed to clean the engine with gasoline.
For cleaning the car body braid with moderate and low temperatures (up to - 27 0 С) Used liquid auto-product preparations "Choysterifier - 2 glasses", containing alcohols, surfactants, etc. This remedy can be poured into the bracket of the opener of the glass in pure form Or diluting with water in a ratio of 1: 5. It is not recommended to wash the car's windscreen cleaner for window glass.
To remove contaminants from paints and decorative parts of cars without water use (which is especially convenient in winter time) Applied a "fast remedy with silicone"). When using this tool on the purified surface, a protective film is formed, protecting paintwork and galvanic coatings from harmful atmospheric influences. It is not allowed to clean the paint surfaces to use gasoline.
There are also means for removing scale from the cooling system ("Choosing cleaner - 1 scale"); Nagar removal ("Nagar-Choice"); cleaning and degreasing friction linings ("STOP"); Removing ice and Inea from the glass and defrosting of the castles ("Authority") and others.
10.5.3 Polishing agents
To maintain and restore the gloss of paintwork, the maintenance of its service is applied special polishing agents.
Depending on the life of the car and the state of the paintwork, polishing the following types are used:
For new paintwork coatings (for cars in the first year of operation);
For odd paintworks (for cars operating within 2 - 3 years).
For old paint coatings (after 3 years of operation).
When leaving the old coating, a longer surface polishing is required.
Enhancement of the atmospheric resistance reaches the introduction into the composition of polishing and preservatives, special additives that improve the physicomechanical properties of the obtained on the surface protective filmswhich as a result can withstand up to 5 - 10 miles.

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 impact on a person some colors and color combinations.
When choosing the color combinations of coatings, their harmony must be the first and main condition.
2. For receipt harmonious combinations Colors It is necessary that there is a certain relationship between the colors (contrast or similarity between the colors 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, polluted by road dust, mud and exposed to a periodic washing of hot and cold water With the help of 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.
