Abstract

The invention discloses a formula of a soft polyurethane composite waterproof sound-absorbing film. The formula comprises polyether polyol, toluene diisocynate, a stannous octoate catalyst, a triethylenediamine catalyst, organic silicone oil, dichloromethane, a phosphate flame retardant and melamine. Use amount of each raw material is limited. According to the invention, formability is excellent, generation of foam structured pinholes during the foaming process is minimized, and foams of a product are fine and uniform. By addition of a reactive flame retardant phosphate (preferably FR-117) and the additive flame retardant melamine, a molecular structure of a cavernous body contains high content of fire retardant elements, and physical property of the product burning core is prevented from being poor. Meanwhile, use amount of water is controlled, and foams coarsening and resilience force descending due to too much water and too many urea-containing chains generated by a reaction are prevented.
