NOVELTY - Multi-purpose bulletproof coating comprises component (A) and component (B), where the component A and the component B are sprayed in a ratio of 1:1-1:3 to form a bulletproof coating. USE - The coating is useful in military and security application. ADVANTAGE - The coating has excellent anti-elasticity, explosion-proof performance and anticorrosive effect, and long-lasting wear resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of multi-purpose bulletproof coating, involving (i) (a) adding polyurethane and polyether polyol into a reaction kettle, continuously stirring, heating at 80-120 degrees C, vacuumizing for 0.5-3 hours, and (b) lowering the solution temperature to 40-70 degrees C, adding aliphatic isocyanate and carbon nanotube composite filler, constantly stirring for 0.5-2 hours, heating at 75-95 degrees C and reacting for 1-5 hours, (ii) (c) adding polyether diamine, dispersing agent and aerogel, stirring for 0.5-2 hours, uniformly dispersing and vacuumizing, and (d) adding polyetheramine, compatibilizer and leveling agent in the solution in sequence, stirring for 0.5-2 hours and vacuumizing at the same time, and (iii) heating component (A) and component (B) at 50 degrees C, and using high-pressure spraying equipment to spray at a volume ratio of 1:1-1:3 to produce the product.
