摘　　要：根据电机接线盒的技术要求,制备了阻燃的PPO/HIPS复合材料,分析了不同粘度的PPO树脂、增韧剂SBS和阻燃剂对复合材料性能的影响。PPO与HIPS共混相容性很好,注塑无分层。SBS对PPO/HIPS复合材料有相容增韧作用,当SBS用量为5%时材料的缺口冲击可达到25.4 kJ/m^2。将TPP和Mg(OH)_2混合使用量达到13%左右时,可以实现复合材料的V0级阻燃,并且可较好的保持复合材料的韧性和维卡软化温度。According to the technical requirements of the motor junction box,the flame retardant PPO/HIPS composite material was prepared,and the influence of the different viscosity of PPO resin,the toughening agent SBS and the flame retardant on the properties of the composite material was analyzed.PPO is compatible with HIPS,and the injection molding is not stratified;SBS has a consistent and toughening effect on PPO/HIPS composites.When SBS dosage is 5%,the material gap impact can reach 25.4 KJ/m2.When the combined use of TPP and Mg(OH)2 is about 13%,the V0 stage flame retardant of composite materials can be realized,and the toughness of composite materials and the softening temperature of vika can be kept well.
