摘要

The flame-point foaming fire-retardant resin compsn. comprises 100 wt.pts. of PVC resin; 0.5-10 wt.pts. of P-toluenesulfonyl semicarbazide as a glowing agent having above a decomposition temp. higher by at least 50 deg.C than the processing temp. of the resin compsn.; 30-70 wt.pts. of trimethyl propane trimethacrylate as a plasticizer; 1-20 wt.pts. of antimony trioxide as a fire-retardant agent. The fire retardant agent can further include boric acid zinc, or inorganic material of magnesium hydroxide, aluminium hydroxide or calcium carbonate.
