通过自由基接枝法在双酚A型环氧树脂分子上引入顺丁烯二酸酐,所得产物经水解,中和制得自乳化性能的水性环氧树脂. 考察了环氧树脂的种类、溶剂、引发剂的种类及质量分数、反应温度、反应时间、顺丁烯二酸酐的质量分数、中和剂及助溶剂对水性环氧树脂的水分散性和储存稳定性的影响. 结果表明:当顺丁烯二酸酐质量分数为30%、引发剂过氧化苯甲酰的质量分数为3%(两者均以E-20环氧树脂的用量为基准),接枝反应温度为100 ℃,反应时间为9 h,中和剂为N,N-二甲基乙醇胺,pH值为7.0~7.5,选用二氧六环和乙二醇单丁醚的混合物作溶剂时制得固含量为25%的水性环氧树脂,其储藏稳定期为2个月.

A self-emulsifiable water-borne epoxy resin was prepared by the free radical grafting reaction of bisphenol A type epoxy resin with maleic anhydride. The influence of the epoxy resin type, the type and mass fraction of initiator and solvent, the temperature and time of reaction, and the mass fraction of maleic anhydride, neutralizer and cosolvent on the dispersion and stability of the self-emulsifiable water-borne epoxy resin were explored. The result showed that the water-borne epoxy resin with 25% solid contents is obtained and it can be stored stably for two months at 30% of mass fraction of maleic anhydride, 3% of mass fraction of benzoyl peroxide (both based on the dosage of E-20),pH 7.0~7.5,N,N-dimethyl ethanolamine as the neutralizer,the mixture of ethylene glycol monobutyl ether and dioxane as solvent,temperature of 100 ℃ and reaction time of 9 hours.
