摘要
采用氮-磷无卤阻燃剂制备出具有良好阻燃性能的热塑性聚酯弹性体(TPEE)。研究表明阻燃剂对TPEE阻燃性能和热性能都有显著改善,其中三聚氰胺磷酸酯(MP)阻燃剂的阻燃效果最好,氧指数可以达到30%,垂直燃烧达到UL-94V-0级,点燃时间为341s,到达热释放速率峰值的时间为355s的p_(kHRR)达到134KW/m^2,总释放热(THR)最小。电学性能研究表明,由于阻燃剂的加入,抑制了TPEE极性基团的极化和能量损耗,降低了TPEE的介电常数,提高了其绝缘性能。氮-磷无卤阻燃剂的添加对热塑性聚酯弹性体的性能影响很大。
In order to improve the flame retardant properties of thermoplastic polyester elastomer(TPEE), the thermoplastic polyester elastomer with good flame retardancy was prepared by using phosphorus-nitrogen halogen-free flame retardants. The results show that the flame retardancy and thermal properties of the TPEE were significantly improved. The flame retardant effect of melamine phosphate is the best among them, and oxygen index could reach 30%, vertical combustion level was UL-94 V-0, ignition time is 341 s, the peak heat release rate reached 134 KW/m^2 at 355 s and the total release heat was minimal. Electrical performance studies have shown that because of the addition of flame retardants, not only suppressed the polarization and energy loss of TPEE polar groups, and reduced the dielectric constant of TPEE, but also the insulation performance was improved. It is indicated that the addition of nitrogen-phosphorus halogen-free flame retardants has great influence on the properties of thermoplastic polyester elastomer.
