Abstract
Development paint and varnish compositions to protect metal and non-metallic surfaces is one of the priorities of fire safety in the operation and repair of rolling stock, since the cost of measures aimed at eliminating the effects of fires is many times higher than the cost of their prevention. The possibility of increasing the fire retardant effectiveness of water-dispersion acrylic-styrene paint and varnish coatings with the help of dispersed mineral fillers is considered. Ammonium polyphosphate and hollow ash aluminosilicate microspheres were used as fillers. The assessment of the flame retardant properties of the resulting coatings was evaluated by the «fire tube» method, the characteristics of the coke expanded layer and the oxygen index. Organic-based protective coatings provide anti-corrosion functions, but in most cases have negligible flame retardant effectiveness. However, such coatings provide more opportunities, so by increasing their thickness, you can increase the fire protection of products, contribute to the localization of fire development, a significant slowdown in the rate of flame propagation and allows you to connect active extinguishing agents. The flame retardant efficiency of the compositions, which swell up depends largely not only on the volume and density of the coke expansion layer, which is formed during combustion, but also on its resistance to burnout and mechanical destruction, adhesion to the protected surface after expansion. In the course of the studies on the primary assessment of the flame retardant efficiency of the developed coatings, it was shown that the introduction of aluminosilicate microspheres makes it possible to increase the strength of the foam coke layer while maintaining a sufficient expansion coefficient and transfer the developed materials from the group of combustible to the group of combustible polymeric materials.
