快干型水性环氧乳液的制备及应用研究

Preparation and Application of Fast Drying Waterborne Epoxy Emulsion

选用相对分子质量大的混合环氧树脂,采用外乳化工艺制备出快干型水性环氧乳液。使用快干型乳液制备适合湿碰湿施工工艺的双组分水性快干环氧防锈底漆,喷板测试漆膜的相关性能,并探讨了不同颜基比、不同种类固化剂对最终漆膜性能的影响。

A fast drying waterborne epoxy emulsion was prepared by the external emulsification process using the mixed epoxy resin with large molecular weight.The fast drying waterborne epoxy emulsion was used to prepare two-component water-based quick drying epoxy antirust primer suitable for wet-on-wet process.The related properties of paint film were tested by spray board,and the effects of different ratios of pigment to binder and different kinds of curing agents on the properties of final paint film were discussed.
