摘　　要：对比研究了红磷、次磷酸盐、烷基次磷酸盐三种无卤阻燃剂在玻纤增强聚对苯二甲酸丁二醇酯(PBT)中的各项力学性能、阻燃性能及磷化氢(PH_3)释放量,并研究了通过匹配不同电势的金属化合物缚酸剂及螺杆组合对PH_3释放量的影响。结果表明,使用烷基次磷酸盐复配阻燃体系,无卤阻燃增强PBT材料可以达到UL94 V-0(1.5mm),同时无PH_3释放,综合力学性能优异,从而用于具有磷化氢限制要求的终端电子电器接插件行业。The comparative study of three halogen-free flame retardant agents including red phosphorus,phosphate, alkyl phosphate in glass fiber reinforced polybutylene terephthalate （PBT） on the mechanicalproperties, flame retardance and hydrogen phosphate （PH3 ） emissions were performed. And the impact onthe release of PH3 by matching the different potential of the metal compound acid binding agents and screwcombination was studied. The results show that： the use of alkyl phosphate compound flame retardant systemcould make halogen-free flame retardant reinforced PBT composite reach the flame class of UL94 V-0 （1.5mm）. Meanwhile, no PH3 releases and the PBT composite has excellent comprehensive mechanicalproperties, which can be used in the terminal electrical and electronic connectors industry that has phosphinerestrictions.
