摘要
分别以三聚氰胺氰尿酸盐(MCA)和氢氧化镁(MH)为阻燃剂制备了聚酰胺6(PA-6)阻燃复合材料,研究和对比了MCA和MH对复合材料的阻燃性能、力学性能影响。结果表明,当MCA和MH用量同为20份时,PA-6/MCA复合材料的极限氧指数(LOI)达到30.5%,而PA-6/MH复合材料的LOI仅为23.5%,说明MCA的阻燃效率比MH高。同时,PA-6/MCA复合材料的拉伸强度为66.8 MPa,是PA-6/MH复合材料的1.14倍。熔体流动速率PA6/MCA复合材料熔体流动速率达74 g/10min,是PA-6/MH复合材料的4.9倍。
The flame-retardant PA-6 composites were prepared by filling MCA or MH. The effect of this two halogen-free flame retardants on the flame retardancy, mechanical property and rheological property of the composites were studied and compared. The results show that when MCA or MH is 20 phr ,the LOI of the PA-6/MCA composites is 30.5% , meanwhile, the LOI of PA-6/MH composites reaches to 23.4%, so, the flame-retardant efficiency of MCA is higher than that of MH. The tensile strength of the PA-6/MCA composites is 66.8 MPa , which is 1.14 times higher than that of PA-6/MH composites. PA- 6/MH composites MFR achieves 74 g/10min, which is 4.9 times more than that of PA-6/ MH composites.
