Abstract

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.
