摘要
采用双酚A型环氧树脂与非离子表面活性剂反应,合成了反应型水性环氧乳化剂,将具有表面活性的分子链段引入到环氧树脂分子链中,用相反转技术制备水性环氧树脂乳液。为了改善乳液与固化剂的相容性,合成了聚醚型水性环氧树脂固化剂,用其制备的双组分水性环氧防腐涂料具有优异的机械性能、耐水性、耐盐水性及耐盐雾性。
A reactive waterborne epoxy emulsifier was synthesized by bisphenol A type epoxy resin and nonionic surfactant.The surfactant molecular chains were introduced into the epoxy resin.The epoxy resin emulsion was prepared by phase inversion technique.In order to improve the compatibility of the emulsion with the curing agent,polyether waterborne epoxy curing agent was synthesized.The synthesized two component waterborne epoxy anticorrosion coatings has excellent mechanical properties,water resistance,salt water resistance and salt fog resistance.
