摘要: 本文采用化学改性法,以环氧氯丙烷、共聚物P105、环氧树脂E-51和双酚A为原料,制备了一种水性环氧树脂乳液作为玻璃纤维成膜剂,研究了原料摩尔比、E-P105用量和乳化温度对乳液粒径和稳定性的影响。结果表明,当P105、ECH、NaOH摩尔比为1∶1.5∶1.2,环氧树脂与双酚A摩尔比为2.25∶1,E-P105质量份数为环氧树脂和双酚A质量的20%,乳化温度为60 ℃时,乳液粒径为0.387 μm,粒径分布均匀,具有良好的稳定性,经上浆处理后的玻璃纤维复合材料力学性能优异。

Abstract: In this paper, a waterborne epoxy resin emulsion was prepared as a glass fiber film former by chemical modification method using epichlorohydrin, copolymer P105, epoxy resin E-51 and bisphenol A as raw materials. The effects of molar ratio of raw materials, E-P105 content and emulsification temperature on the particle size and stability of the emulsion were investigated. The results showed that when the molar ratio of P105, ECH, NaOH was 1∶1.5∶1.2, the molar ratio of epoxy resin and bisphenol A was 2.25∶1, the mass of E-P105 was 20% of the total mass of epoxy resin and bisphenol A, and the emulsification temperature was 60 ℃, the particle size of the emulsion was 0.387 μm with uniform particle size distribution and good stability, sized glass fiber composites have excellent mechanical properties.
