A PAINT COMPOSITION OF TWO LIQUID TYPE HAVING HIGH FLAME-RESISTANCE PROPERTY CONTAINING ALUMINIUM HYDROXIDE

摘要

The present invention relates to a flame retardant composition suitable for a railway vehicle and all kinds of vehicles and more specifically, to a natural drying type two component paint composition with high flame resistance using aluminium hydroxide. The present invention is a two component flame retardant composition using main materials and curing agents by mixing ingredients. The main materials includes 30-55 wt% of acrylpolyol, 1-10 wt% of cellulose acetate butylate (CAB) modified acryl polyol, 5-25 wt% of aluminium hydroxide, 5-25 wt% of silica, 3-20 wt% of pigment, 0.1-2 wt% of dispersing agent, 0.1-1 wt% of leveling agent, 0.001-0.1 wt% of hardening accelerator, 0.1-2 wt% of anti-sagging agent and 5-15 wt% of solvent. The curing agent includes 70-90 wt% of polyisocyanate and 10-30 wt% of solvent.
