RF 2352601, C09D 5/02, C09D 5/18, 32 27/20; publ. 20.04.2009).
The known method of technologically sophisticated and includes several stages.
A method of obtaining fire-resistant coating, including coating the surface of several layers of a composition containing a binder and filler, with intermediate drying of each layer and final heat treatment coverage, wherein the first on a surface put a heat-insulating layers, and then fire-resistant layers, the drying of each of the intermediate layer is carried out at 20-80 degrees and in the final heat treatment coverage at 80-150°with the total thickness of the fire-resistant layers does not exceed 3 mm (Pat. RF 2039070, C09D 183/04, C09D 5/18, B05D 1/38, publ. 09.05.1995).
However, the composition of the composition in this method with many components to it, the technology involves several stages, the coating has a greater thickness.

The coating is applied paint, or brush on the earlier painted design thickness up to 3 mm, including complex shape (double tee, , various devices and aggregates), and in field conditions, i.e drying temperature should be 18-25°(Pat. RF 2186813, C09D 123/34; publ. 10.08.2002)..
However, this method is applicable to steel structures, requires large thickness of the coating. The composition has a complicated recipe.
The closest one is a method of fire protection of metal structures by the application of fire retardant coating on the basis of post chlorinated polyvinyl chloride resin, organic solvent in a combination with filler - product of condensation of formaldehyde, , sorbitol, oxalic acid.

However, this method requires a long exposure, the greater thickness of the coating and used for drawing on the metal construction. Composition of the coating technologically diffcult due to the complexity of synthesis of a blowing filler.
Task: to develop a fire retardant coating on the basis of post chlorinated polyvinyl chloride resin and fiberglass.
The technical result is the reduction in the thickness of the applied coating, reduction of time of drying of the coating and provision of high fire protection for fiberglass.

The presence in the of atoms of phosphorus, boron and nitrogen, which are inhibitors of combustion and oxidation, fireproof compositions on the basis of post chlorinated polyvinyl chloride resin. Furthermore, a high content of phosphorus and boron in the structure of substances, promotes achievement of the maximum result, without resorting to the use of large concentrations.
The stated limits due to the fact that decreasing of leads to a decrease in fire resistance, and improving its content helps to increase the cure time of composition. Statement of the coating thickness is because when you decrease the thickness of the coating does not achieve the required fire-resistant properties, and the increase in the thickness of the coating leads to the increase of curing time of composition.
This composition enables one to obtain coatings on the basis of post chlorinated polyvinyl chloride resin with high fire retardant.
Method of applying a fire retardant coating on the glass-fiber plastic is as follows.
Before coating on the basis of post chlorinated polyvinyl chloride resin composition is entered oligomer. This method is used for fire protection of fiberglass. The resulting structure is applied repeatedly to samples of fiberglass with a brush with a layer thickness of 1 mm Samples of bearing the coating are dried on air within 2 days under normal conditions.
To determine the effectiveness of the developed flame retardants tests of coatings, the impact of the treated sample fiberglass source of ignition. Installation for testing the collected on the basis of the laboratory of chemical tripod and set in a well ventilated area. Samples for measurements have the following dimensions: length - 50 mm, a width of 50 mm, thickness of 1.8-2 mm fire retardant coating Thickness 1 mm in Front of the dimensions covered with samples are dried at room temperature for at least two days. Prepared for the test sample is fixed in a tripod vertically. Using universal gas burner flask containing a nozzle diameter 7 mm Gas burner (use household gas), which is in the horizontal position on a distance of at least 200 mm from the sample, light and adjusted to the height of the flame was 150-180 mm Flame send the exact center of a fixed sample fiberglass. Air supply govern until disappears yellow tip of the flame.
Temperature measurements are held device with a pyrometer With-300.3 (GOST 28243-96 «Pyrometers. General technical requirements»). Principle of operation of the pyrometer is based on the measurement of the heat radiation of the object of measurement predominantly in the range of infrared and visible light.
Using thermometer record the temperature change on the unheated surface prototype over time until they reach the ultimate state of a prototype fiberglass. The limiting state of the material was taken emergence of black spots on the unheated side of the prototype - the loss of integrity of the sample. Next, measure the height of the formed coke, the change of thickness of the sample before and after the test is calculated coefficient of expansion.
In the result of the test showed that made the coefficient of swelling of the order of 5.55-6,47 allowed to reduce significantly the loss of mass of the sample from 24.7% to 6.2%and 8.6%, and the time to reach the ultimate state of prototypes is increased by 1.7-2.0 times (table 2).
