Abstract

A preparation method and uses of a high-performance water-soluble acrylic resin with high solid content and low viscosity. The method polymerizes the free radical solution in a mixed solvent by a continuous method to produce an acrylic resin and the resin is rendered water-soluble through salification. Modification with versatate introduces a large branched structure. Silicone functional monomer is used to modify the acrylic resin. Amino resin is used as a curing agent to directly prepare a waterborne amino-acrylic coating with a simple process, and the coating has good hardness, fullness, water and alcohol resistance and salt spray resistance.
