摘要
Abstract
In order to improve the flame retardancy of polycarbonate/acrylonitrile-butadiene-styrene(PC/ABS)alloy,the flame retardant formula system was explored by the method of compound synergy.Taking the limiting oxygen index(LOI)and vertical combustion grade(UL-94)of PC/ABS composites as the main indexes,a binary flame retardant formula system with aluminum diethylphosphinate(ADP)as the main flame retardant and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide(DOPO)as the synergistic flame retardant was constructed.PC/ABS/binary flame retardant composites were prepared by mixing PC/ABS and binary flame retardant systems.The flame retardancy,mechanical properties,combustion characteristics and thermal stability of PC/ABS composites were studied by UL-94 vertical combustion test,oxygen index(LOI)test,mechanical property test,cone calorimetry test and thermogravimetric analysis test.The results show that when the mass ratio of ADP to DOPO is 3∶1 and the total addition amount of binary flame retardant formula system is 15.0%,PC/ABS composites have excellent flame retardancy,mechanical properties,combustion characteristics and thermal stability.关键词
