The present invention relates to improving the flame adhesion of polyurethane foam, and more particularly, to a new polyol for improving the flame adhesion of the polyurethane foam and a polyurethane foam prepared using the same.n n n The flexible polyurethane foams according to the invention are prepared by reacting a polyol and polyisocyanate mixture comprising a highly functional polyether polyol and a polyether-polyester hybrid polyol in the presence of a catalyst and a blowing agent,n n n Wherein the polyether polyol is a polyol having 4-8 functional groups and a molecular weight of 1,000-10,000 g / mol,n n n The polyether-polyester hybrid polyol is characterized in that it is prepared by mixing a polycarboxylic acid (polyalkylene oxide) polyol, aliphatic diol, polyfunctional compound with dicarboxylic acid.n n n Polyurethane using the polyol according to the present invention, the flame lamination is excellent in the adhesiveness of the foam, and also good mechanical properties. |
