摘　　要：将3种三聚氰胺氰尿酸盐(MCA)分别与二乙基次磷酸铝(ADP)、SiO_(2)复配,制得了阻燃尼龙66(PA66)复合材料,并研究了其熔体流动速率(MFR)、力学性能和阻燃性能。结果表明:加入MCA可以明显提升阻燃PA66复合材料的MFR;加入ADP/MCA/SiO_(2)复配阻燃剂后,PA66复合材料的力学性能和阻燃性能均得到明显提升,UL94阻燃等级均为V-0级,并均通过了750℃和960℃灼热丝燃烧试验,当含量相同时,与M-1,M-2相比,加入M-3的阻燃PA66复合材料力学性能最好。Flame retardant nylon 66(PA66)composite was prepared by compounding three types of melamine cyanurate(MCA)with diethyl aluminum hypophosphate(ADP)and SiO_(2),respectively.The melt flow rate(MFR),mechanical property and flame retardant property were studied.The results show that the addition of MCA can significantly improve MFR of flame retardant PA66 composite.After adding ADP/MCA/SiO_(2) composite flame retardant,the mechanical property and flame retardant property of PA66 composite are significantly improved.UL94 flame retardant grade is V-0,and both pass the 750℃and 960℃hot wire combustion tests.When the content is the same,compared with M-1 and M-2,flame retardant PA66 composite with M-3 has the best mechanical property.
