Novel two-component joint beautifying agent

Abstract

The invention relates to a novel two-component joint beautifying agent composed of components A and B. The component A comprises, by mass, 70-80 parts of polyaspartic acid ester, 5-15 parts of propylene carbonate, 5-10 parts of fumed silica and 2-5 parts of titanium dioxide, and the component B comprises, by mass, 70-85 parts of polyol and aromatic / aliphatic isocyanate polymer, 8-15 parts of 2, 2, 4-trimethyl-1, 3-pentanediol diisobutyrate and 1-15 parts of diethyl fumarate. The novel two-component joint beautifying agent is composed of polyaspartic acid ester resin and a high-elasticity prepolymer curing agent formed by polymerizing polyol and aromatic / aliphatic isocyanate and has the advantages of being high in yellowing resistance, elastic and solvent-free, the problem that an epoxy resin type joint beautifying agent is not resistant to yellowing and water, is subject to influence of air temperature during construction and cannot be used outdoors is solved, and a gap in domestic joint beautifying industry is filled in.
