摘　　要：以次磷酸铝(AHP)和三聚氰胺氰尿酸盐(MCA)为阻燃剂制备了电线电缆聚苯醚热塑性弹性体(简称PPOW),对材料的阻燃性能、热稳定性及热老化进行了研究。结果表明,当阻燃剂总用量为40份,AHP/MCA为1︰1,PPOW能通过UL94(3 mm)V-0级别,氧指数为27.2%。阻燃剂的加入有效改善PPOW的热稳定性。当PP含量低于25份,PPOW能满足GB/T 32129-2015中关于“最高允许电线电缆导体工作温度125℃”的使用要求。Polyphenylene oxide thermoplastic elastomer for wire and cable(PPOW)was prepared with aluminum hypophosphite(AHP)and melamine cyanurate(MCA)as flame retardants.The flame retardancy,thermal stability and thermal aging of the material were studied.The results show that when the total dosage of flame retardant was 40 phr,AHP/MCA was 1︰1,PPOW can pass UL94(3 mm)V-0,and the oxygen index was 27.2%.The addition of flame retardant can effectively improve the thermal stability of PPOW.When the content of PP was lower than 25 phr,PPOW can meet the requirements of“maximum allowable working temperature of wire and cable conductor 125℃”in GB/T 32129-2015.
