What do the standards regulate?

Brands of oil compositions depend on the type of drying oil used.

Manufacturers produce thickly grated oil compositions, which must be diluted with drying oil before use, and liquid ones that are ready for use.

Some provisions of the documents

GOST 8292 85 for oil-based colored thick-based paints defines the following brands:

  • MA-021 - on natural drying oil;
  • MA-015 and MA-025 – on a combined or natural film-forming substance;
  • GF-023 – on glyphthalic drying oil;
  • PF-024 - on a pentaphthalic analogue.

The main characteristics of thickly grated oil-based paints and varnishes must comply with this GOST.

Thickened paints should be diluted before use.

  1. Grades MA-015 and 025 – 20/30% drying oil of the total volume of material. The composition of MA-15 based on red lead, mummy and ocher pigments is diluted with 30/40% film former.
  2. MA-015 paints in all types of colors are diluted with natural drying oils or combined analogs of K/3 and K/5.
  3. Compositions MA-025 are diluted with natural drying oil, “Oxol” or combined oils K/2, K/3 and K/5.
  4. Analogues of the GF and PF brands are diluted to the desired consistency with appropriate film formers.
  5. Oil paint according to State Standard 8292 85, after diluting it with drying oil, can be diluted with a solvent as necessary. Its volume should be no more than 5% of the mass of the paintwork material.

Some of the characteristics of the compositions, according to the standard.

Note! To obtain a high-quality liquid coating ready for use, oil paints in accordance with State Standard 10503 71 must be diluted in a certain ratio. It is 50 g of oil per 1 kg of thickly grated paint.

The most important material characteristics

The photo shows paint made according to the interstate standard.

To choose the paint correctly, you need to be guided by its technical characteristics. It should be taken into account that since 2003, State Standard 30884 2003 has been in force in the Russian Federation for ready-to-use oil paints.

This standard is interstate, i.e. it is accepted in all CIS countries.

  1. The mass fraction of film-forming agent in paintwork materials must be at least 26% . This component determines the ability of the finish to create a monolithic coating when applied to the base. The more film former, the better the paint will adhere to the surface. However, this also complicates its preservation.

If the paint is sealed in a can, it can last for years. After contact with air, it cannot be stored for a long time. The composition will harden quickly.

  1. The proportion of volatile substances in the paint should not be more than 10 percent . These components evaporate at temperatures above +20 degrees. Such substances have a pungent odor and are harmful to our health.
  2. The degree of grinding of paint components . The finishing features depend on it. You can create two types of coating with your own hands: smooth (the grinding of components is less than 90 microns) and a fine-grained analogue (all paint particles have a diameter of less than 90 microns).

The viscosity of the paint can be checked with a capillary viscometer.

  1. The viscosity of the dye affects its fluidity and drying period . The first indicator should be 65/140 units. The maximum period during which oil paints harden according to State Standards should be one day.
  2. The most important characteristic is the hardness of the paint coating . This value determines the ability of the film to prevent solid objects and bodies from penetrating deep into it. According to State Standards, oil-based thick paints must have this indicator of at least 0.13 units.
  3. A separate point of characteristics is the hygroscopicity of the coating, i.e. its ability to transmit moisture (in connection with it - the paint’s resistance to water).

For compositions intended for external work, the value should approach zero. A resistance level of 0.5/1 is acceptable for compositions used for interior finishing work.

SAFETY REQUIREMENTS

2.1. Paints are a fire hazardous and toxic material, which is due to the properties of the substances included in their composition: gasoline solvent for the paint and varnish industry, lead dust. Solvent vapors contained in paints have an irritating effect on the mucous membranes of the eyes, respiratory tract and skin. Lead crop causes changes in the nervous system, blood, and blood vessels.

2.2. During the production, use and testing of paints, safety and industrial sanitation rules in accordance with GOST 12.3.005-75 must be observed.

(Changed edition, Amendment No. 1).

2.5. Persons associated with the production and use of paints must be provided with special clothing and personal protective equipment in accordance with GOST 12.4.011-89. To protect hands, pastes such as “biological gloves” should be used.

2.6. Fire extinguishing agents: sand, felt, foam, water, fire extinguishing powders.

2.7. Paint coatings after drying do not have a harmful effect on the human body.

2.8. Monitoring compliance with maximum permissible emissions (MPE) - in accordance with GOST 17.2.3.02-78. Waste disposal is carried out in accordance with the sanitary rules for the accumulation, transportation, neutralization and disposal of toxic industrial waste. (Introduced additionally, Amendment No. 1).

ACCEPTANCE

3.1. Rules for acceptance of paints - according to GOST 9980.1-86.

3.2. The need for testing according to the recommended indicators in Table 2 is established by the manufacturer and the consumer when concluding a contract for the supply of products.

3.3. Every hundredth batch is subjected to periodic testing for compliance with all requirements and standards of this standard.

3.4. If unsatisfactory results of periodic tests are obtained, the manufacturer checks each batch until satisfactory test results are obtained in a row of at least three batches. Sec. 3. (Changed edition, Amendment No. 1).

TEST METHODS

4.1. Sampling - according to GOST 9980.2-86.

4.2. Preparation of samples for testing Before testing, the paint is thoroughly mixed. The mass fraction of film-forming substances and volatile substances, as well as the degree of grinding, are determined without diluting the paint. To determine other indicators, paints are diluted to a painting consistency with drying oils in an amount of 20-30% for brands MA-015, MA-025 and 30-40% for brands MA-015 red lead, MA-015 mummy, MA-015 ocher by weight of thickly rubbed paints: paints brand MA-015, MA-015, red lead (mummy, ocher) - natural drying oil or combined K-3, K-5; MA-025 brand paints - Oxol drying oil or combined K-2. The diluted paints are filtered through a 056 N sieve (GOST 6613-86) and applied with a brush to the prepared plates. Dryer grade NF-1 (GOST 1003-73) or grade ZhK-1 is added to paint made with ocher up to 2% by weight of the paint. Plates for applying paints are prepared in accordance with GOST 8832-76, section 3. The color of the film, the drying time of the paint, the conditional light fastness of the film and its resistance to static action of water are determined on plates made of steel grades 08kp and 08ps in accordance with GOST 16523-89 or from cold-rolled steel in accordance with GOST 9045-93, size 70x150 mm and thickness 0.5-1 .0 mm or on plates made of black tin according to GOST 13345-85, size 70X150 mm and thickness 0.26-0.32 mm. Film hardness is determined on special-purpose glass plates measuring 90X120 mm and thickness 1.2 mm according to TU 21-0284461-058-90. To determine the color, the paint is applied until the substrate is completely covered and dried for 24 hours at a temperature of (20±2) °C. To determine the drying time and hardness of the film, paint is applied with a brush in one layer, to determine the conditional light resistance of the film and the resistance of the film to the static effects of water - in two layers. Each layer is dried for 24 hours at a temperature of (20±2) °C. When determining the conditional light resistance of the film, the first layer is dried at a temperature of (20±2) °C for 24 hours, the second - for 120 hours. The coating thickness of a single-layer coating after drying should be 25-30 microns, two-layer - 50-60 microns.

4.3. The color of the dried paint film is determined by visual comparison with the color of the corresponding color samples (standards) of the “Color Standard Card Files” or control color samples in natural or artificial daylight diffused light. The samples being compared should be in the same plane at a distance of 300-500 mm from the observer’s eyes at a viewing angle that excludes surface gloss. In case of disagreement in color assessment, the color determination in natural daylight is taken as the result.

4.2, 4.3. (Changed edition, Amendment No. 1).

4.4. The mass fraction of the film-forming substance in the paint is determined according to GOST 17537-72. Acetone (GOST 2768-84) or a mixture of acetone and ethyl alcohol (GOST 17299-78) in a ratio of 3:2 by volume is used as a solvent.

4.5. The mass fraction of volatile substances is determined according to GOST 17537-72. A sample weighing 1.5-2.0 g is placed in a drying oven and kept at a temperature of (140±2) °C. The first weighing is carried out after 1 hour of exposure in the cabinet, and subsequent weighings are carried out every 30 minutes until a constant weight is achieved. It is allowed to determine the mass fraction of volatile substances under an infrared lamp at a temperature of (140±2) °C. In case of disagreement in the assessment of the mass fraction of volatile substances, the final result is determination in an oven.

4.6. (Deleted, Amendment No. 1).

4.7. The conditional light resistance of the film is determined according to GOST 21903-76, method 3. The use of PRK-2 or DRT-375 lamps is allowed. The distance of the samples from the surface of the lamps should be (350±5) mm. The steady state of the lamp should be as follows: voltage (120±6) V, current (3.75±0.25) A. The film is irradiated for the time specified in clause 8 of Table 2. Irradiated samples are examined with the naked eye and compared with non-irradiated samples. Slight loss of gloss of the paint film and slight color change are acceptable. (Changed edition, Amendment No. 1).

4.8. The resistance of the film to the static effects of water is determined according to GOST 9.403-80, section. 2. Samples are placed in distilled water (GOST 6709-72) and kept in it for the time specified in paragraph 9 of Table 2. After testing, the samples are kept in air at a temperature of (20±2)°C for 2 hours and the appearance of the film is examined. After testing, the film should not peel off, wrinkle or have bubbles.

Slight loss of gloss and slight change in film color are acceptable.
