摘　　要：为了开发出一种合成简单、便于保存,且不会对环境造成污染的阻燃剂,以双咪唑离子液体为单体,通过活性聚合反应和阴离子交换反应合成了磷氮膨胀型阻燃剂聚1-丁基-3-(1-乙烯基咪唑-3-己基)咪唑磷酸氢盐和聚1-丁基-3-(1-乙烯基咪唑-3-己基)咪唑磷酸二氢盐,研究了不同阻燃剂与聚氯乙烯的比例对聚氯乙烯电缆料极限氧指数的影响。结果表明:随着体系中阻燃剂与聚氯乙烯的质量比从1∶5到4∶9,聚氯乙烯电缆料的极限氧指数可从28%提高到34%;并且同等比例下,聚1-丁基-3-(1-乙烯基咪唑-3-己基)咪唑磷酸氢盐对极限氧指数的提高要优于聚1-丁基-3-(1-乙烯基咪唑-3-己基)咪唑磷酸二氢盐。In order to develop a flame retardant which is easy to synthesize, convenient to preserve and will not pollute the environment, a polyphosphazene-expanded flame-retardant poly1-butyl-3-(1-vinylimidazolium-3-hexyl) imidazolium hydrogen phosphate salt and a poly1-butyl-3-(1-vinylimidazolium-3-hexyl) imidazolium phosphate dihydrogen salt are synthesized by living polymerization reaction and anion exchange reaction with a bis-imidazole ionic liquid as a monomer. The relationship between the oxygen index and the ratio of different flame-retardants and polyvinyl chloride(PVC) is studied. The proportion of flame retardants and PVC as the system from 1∶5 to 4∶9, the limiting oxygen index of PVC cable materials is increased from 28% to 34%, and under the same proportion, poly1-butyl 3-(1-vinyl imidazole-3-hexyl) imidazole hydrogen phosphate salt performance on the improvement of oxygen index is superior to poly1-butyl 3-(1-vinyl imidazole-3-hexyl) imidazole dihydrogen phosphate salt.
