摘　　要：采用锥形量热仪对酚醛环氧树脂(NR)和磷酸三苯酯(TPP)对高抗冲聚苯乙烯(HIPS)阻燃性能的影响进行研究。结果表明,NR主要通过成炭作用在凝聚相中发挥作用,而TPP则主要通过自身挥发在气相来抑制燃烧,两者并用具有明显的阻燃和抑烟协同效应,同时有效地降低了材料的有效燃烧热。The cone calorimeter was used to study the effect of triphenyl phosphate （TPP） and novolac resin （NR） on flame-retardant properties of HIPS in the paper. The results showed that NR played a main part in the solid phase by its char-formation and TPP dominated in the gas phase. There was the synergistic effect of flame retardancy and smoke suppression and effectively decreased the effective heat of combustion （EHC） when NR and TPP were incorporated into HIPS simultaneously.
