摘要：采用线型酚醛树脂与磷-氮阻燃剂制备出具有良好阻燃性能的无卤阻燃热塑性聚醚酯弹性体(TPEE)。研究表明使用磷-氮阻燃剂无法制备出抗熔滴的TPEE。酚醛树脂引入可以有效抑制熔滴,同时热重分析结果表明线型酚醛树脂的引入,可以提升材料的高温残留量,扫描电镜测试结果表明酚醛树脂的引入有助于形成致密炭层,提升体系的阻燃性能。
The flame retarding synergism of novolac as char agent with the phosphorous nitrogen(P-N)flame retardant system was investigated in thermoplastic polyester-ether elastomer(TPEE)composites containing aluminum diethylphosphinic(AlPi)and melamine polyphosphate(MPP).The results show that the sample reaches the vertical burning(UL94)V2rating by adding phosphorous-nitrogen combined flame retardants which can not prevent melt dripping during the burning process of the materials.The results of TG show that the remained residue at high temperature increases with addition of novolac.The images of SEM demonstrate that the novolac results in formation of stable compact carbonaceous char which prevents the melt dripping and gets UL94-V0 rating.
