難燃性 軟質 Polyurethane Foam의 製造에 관한 硏究
姜斗煥,金奎權 단국대학교 대학원 1984 學術論叢 Vol.8 No.-
Falme retardant polyurethane foam was prepared by foaming mixed polyether polyol which has different OH value, such as OH No. 56,560,840, etc. with TDI, and added various retard agent to the compounds mixture. As the result of the mechanical and flammability test of the foam, tensile strength and tear resistance were decreased, and compressive strength and flame retardancy were a little increased, as the amount of polyether polyol with higher OH value was increased. The flame retardant agent such as tricresyl phosphate (TCP), Tri (βchloro ethyl) phosphate(TCEP), PHT_4-diol (PHT_4) and Sb_2O_3 was added to the compounds foaming, and the flammability and the mechanical properties of the foams were measured. As the result of the mechanical and flammability test of the foam increased the various the result of the mechanical and flammability test of the foam increased the various retardant agenciesy, the flammability resuet showed better in the order of PHT_4 TCEP, TCP, and Sb_2O_3, and the mechanical properties were similar to the result in case of the foam prepared with mixed polyether polyol having different OH value with TDI.
