Abstract

The invention discloses fire-retardant hydrolysis-resistance solvent-free polyurethane synthetic leather resin. The resin is prepared by mixing a component A and a component B according to the mass ratio of 2:1-1:2. The component A comprises 30-60 parts of polyether diols, 20-50 parts of polyether triols, 0-5 parts of chain extender, 0-2 parts of cross linking agent, 0-10 parts of additive-type flame retardant, 0-5 parts of reactive-type flame retardant, 0-1 part of foaming agent, 0-0.5 part of catalyst, 0-0.5 part of foam stabilizer, and 0-1 part of light / heat stabilizer. The component B comprises 50-70 parts of polyether triols, 30-50 parts of isocyanate, and 0-0.1 part of catalyst. The invention further provides a preparation method and application of the resin. The solvent-free polyurethane synthetic leather made from the resin meets BS (British standard) 5852 NO. 0&1 flame standards and FMVOSS (Federal Motor Vehicle Safety Standard) NO. 302 flame standards.
