摘　　要：通过熔融共挤出法制备了阻燃连续长玻璃纤维增强聚丙烯(PP)复合材料,并对其力学性能、腐蚀性、相比漏电起痕指数以及灼热丝起燃温度在玻璃纤维含量相同时,随阻燃剂种类、含量以及玻璃纤维形态的变化规律进行了研究。结果表明,自制复配无卤阻燃剂(OP1120A)和连续长玻璃纤维所制得的复合材料的综合性能最佳,且随着OP1120A含量的增加,材料的力学性能和相比漏电起痕指数值下降,阻燃性能提高;当长玻璃纤维含量为40%、OP1120A含量为17%时,材料的拉伸强度为189 MPa、冲击强度为213J/m、相比漏电起痕指数达到650V、灼热丝起燃温度达到960℃。The influence of types and content of flame-retardants and glass fibers on the mechanical properties,glow-wire ignition temperature,comparative tracking index was investigated.It was shown that the comprehensive performance of composite containing a home-made halogen-free flame-retardant(OP1120A)was the best.Though the mechanical properties and the comparative tracking index decreased,the flame retardant properties increased with increasing OP1120 A content.When the content of long-glass-fiber-reinforced was 40 % and the content of OP1120 A was 17 %,the tensile strength,impact strength,comparative tracking index,and glow-wire ignition temperature of the composite were 189 MPa,213J/m,650 Vand 960 ℃respectively.
