分别以2-羧乙基苯基次膦酸为添加型和反应型阻燃剂,研究了2-羧乙基苯基次膦酸对固化剂1618/环氧树脂固化体系产物热稳定性的影响和2-羧乙基苯基次膦酸对环氧树脂的阻燃/固化作用。结果表明:2-羧乙基苯基次膦酸对固化剂1618/环氧树脂固化体系热稳定性的提高没有明显作用;2-羧乙基苯基次膦酸对环氧树脂有较好的阻燃/固化作用,固化后可得到具有高透明度和良好热稳定性的环氧树脂,且阻燃等级可达到UL94-V0。
The effects of 2-carboxyethylphenylphosphinic acid on the thermal stability of the curing agent 1618 / epoxy resin curing system were studied by using 2-carboxyethylphenylphosphinic acid as additive and reactive flame retardant respectively And 2-carboxyethylphenylphosphinic acid flame retardant / curing effect on epoxy resin. The results showed that 2-carboxyethylphenylphosphinic acid had no obvious effect on the thermal stability of curing agent 1618 / epoxy curing system; 2-carboxyethylphenylphosphinic acid had better epoxy resin Flame retardant / curing effect, after curing can be obtained with high transparency and good thermal stability of the epoxy resin, and flame retardant grade up to UL94-V0.
