阻燃高光泽PC/PMMA合金的制备与性能研究
Preparation and Property Study of PC/PMMA Alloy with High Gloss and Flame Retardancy
【摘要】 以聚碳酸酯(PC)和聚甲基丙烯酸甲酯(PMMA)为主要原料,通过共混获得表面光泽性能优异的合金;利用无卤阻燃剂磷酸酯来改善合金的阻燃性能;使用苯乙烯马来酸酐无规共聚物(SMA)、乙烯-丙烯酸甲酯-甲基丙烯酸缩水甘油酯三元共聚物、苯乙烯-丙烯腈共聚物(SAN)、乙烯-丙烯酸共聚物(EAA)以及乙烯-丙烯酸甲酯(1125)五种不同相容剂来改善PC/PMMA合金体系的相容性。结果发现SAN/1125能够有效地改善体系的相容性;加入8份的磷酸酯体系的阻燃性能可达到V-0级(3.2 mm)。
【Abstract】 With PC and PMMA as main material,the PC/PMMA composites with excellent High-gloss on the surface were prepared by means of the mixing method.The halogen-free flame retardant phosphate was added to improve the flame retardancy of the alloy.In addition,the compatilizers styrene-maleic anhydride copolymer(SMA),ethylene-methacrylate-glycidyl methacrylate,styrene-acrylonitrile copolymer(SAN),ethylene-acrylic acid copolymer(EAA),ethylene-methyl acrylate resin(1125)were incorporated to improve the compatibility of PC/PMMA alloy.It was found that,SAN/1125 can effectively improve the system compatibility;8 phr of phosphate can ensure the flame retardancy up to V-0(3.2mm)level.
