摘要: 以四溴双酚A双环氧丙基醚、四氯化硅、环氧氯丙烷为主要原料合成新型硅、氯、溴三元素协同高效阻燃剂四溴双酚A双\[三(二氯丙氧基)硅酰氧基氯丙基\]醚,并用其阻燃聚氯乙烯(PVC)。探讨了反应溶剂、温度、时间、摩尔比等对反应及产率的影响,并通过傅里叶红外光谱、核磁共振及极限氧指数等测试手段表征了产物的结构及性能。结果表明,最佳工艺条件为:以乙腈为溶剂,四溴双酚A双环氧丙基醚∶四氯化硅∶环氧氯丙烷的摩尔比为1∶2∶7;四溴双酚A双环氧丙基醚与四氯化硅在70 ℃温度下保温反应4 h,再加入环氧氯丙烷在80 ℃温度下保温反应7 h,产率达99 %;目标产物对PVC有较好的阻燃性能。

Abstract: A novel flame retardant was prepared from tetrabromo bisphenolA diepoxypropyl ether, tetrachlorinated silicon, and epoxy chloropropane, in which three elements, silicon, chlorine, and bromine were expected to provide a synergetic effect. The effect of temperature, time, solvent, and mole ration of raw materials was investigated. The optimum condition was as follows: acetonitrile was used as a solvent, molar ratios of (tetrabromo bisphenolA diepoxypropyl ether)/ (tetrachlorinated silicon)/(epoxy chloropropane) was 1∶2∶7; first reaction, 70 ℃ for 4 h, second reaction, 80 ℃ for 7 h; the yield was 99 %. It may render PVC a good flame retardacy.
