POLYURETHANE FOAM HAVING EXCELLENT FLAME LAMINATION PROPERTY USING POLYOL FOR IMPROVING FLAME ADHESIVE PROPERTY AND POLYOL FOR PREPARING THE SAME

摘要

PURPOSE: A method for preparing a polyurethane foam is provided to prepare a polyurethane foam with excellent flame adhesive property to fiber cloth and good mechanical properties. ;CONSTITUTION: A method for preparing a polyurethane foam comprises a step of reacting polyol and polyisocyanate with a foaming agent to prepare a soft flame adhesive polyurethane foam. The polyol includes polyetherpolyol including highly functional polyetherpolyol and a polyether-polyester hybrid polyol, wherein the highly functional polyetherpolyol has a functional group of 4~8 and molecular weight of 1,000-10,000 g/mol and the polyether-polyester hybrid polyol is obtained by reacting polyfunctional poly(alkylene oxide)polyol or aliphatic diol and polyfunctional compound with dicarboxylic acid.;COPYRIGHT KIPO 2011
