And the EA and epoxy modified acrylic resin solid content, viscosity, PH and other performance testing, to ensure that the correct reaction, get qualified epoxy malefic acid ester EA and epoxy modified acrylic resin. And resin materials for preparation of varnish, performance testing, make sure to get to the actual use of indicators. Spraying, baking paint film system, determination of the hardness, adhesion, water resistance and alkali resistance, such as performance, this research epoxy resin content on the influence of water soluble modified acrylic resin coatings film performance. The optimum formulation of epoxy modified acrylic resin. The experimental results show that the dosage of epoxy resin content in epoxy adhesion and hardness of the water soluble modified acrylic resin coating effect is not big, but can cause obvious change to the water resistance and alkali resistance. The appropriate formula can be obtained water-soluble, weathering resistance and mechanical properties are very good water-soluble epoxy modified acrylic resin coating.
