摘要:
为获得适用于聚酰胺66(PA66)的协效型阻燃剂,以植酸(Phytic acid,PA)和三聚氰胺(Melamine,MEL)为原料,采用超分子自组装法制备一种P、N协效型阻燃剂三聚氰胺植酸盐(Melaminephytate,MPA),再将MPA与PA66熔融共混制备成复合材料,通过垂直燃烧仪、极限氧指数仪、锥形量热仪、电子万能试验机等对其阻燃性能、力学性能进行表征,并提出该阻燃剂可能的阻燃机理。结果表明:MPA可提升PA66的阻燃性能,当PA66/MPA复合材料中MPA质量分数达到8%时,垂直燃烧等级达到UL94 V 0级,极限氧指数大于27%,热释放速率峰值和烟雾释放总量显著降低;随着阻燃剂MPA含量的提升,PA66/MPA复合材料的力学性能有所下降,当MPA质量分数达到8%时,拉伸强度与断裂伸长率分别下降27.4%和24.1%;MPA可能的阻燃机理为P、N协效阻燃,二者同时在凝聚相和气相发挥作用,从而提升PA66的阻燃性能。该结果可为工程应用中协效化阻燃PA66的制备提供一定参考。
