Abstract

The present invention relates to an aqueous acrylic resin emulsion, a preparation method, and an application of the aqueous acrylic resin emulsion in a coating material. Polymerization raw materials of the aqueous acrylic resin emulsion comprise the following components: methyl methacrylate, butyl acrylate, hydroxyl acrylic, methyl acrylamide, azobisisobutylnitrile, amino-2-methyl-1-propanol, mercaptoethanol, propylene glycol monobutyl ether, ethylene glycol monobutyl ether and deionized water. The aqueous acrylic resin emulsion is prepared by adding the azobisisobutylnitrile in batch. An aqueous plating coating material adopting the aqueous acrylic resin emulsion as the base resin is further prepared.

Description

technical field [0001] The invention belongs to the technical field of polymer emulsion polymerization, and in particular relates to a water-soluble acrylic resin emulsion, a preparation method and its application in paint. Background technique [0002] Copolymers synthesized from monomers such as acrylates and methacrylates are called acrylic resins, and coatings that use them as film-forming base materials are called acrylic resin coatings. This type of coating has the advantages of light color, color retention, gloss retention, weather resistance, corrosion resistance and pollution resistance, and has been widely used in automobiles, aircrafts, machinery, electronics, furniture, construction, leather finishing, papermaking, printing and dyeing, wood processing, industrial Finishing of plastics and daily necessities. In terms of coating dosage forms, there are mainly solvent-based coatings, water-based coatings, high-solid component coatings and powder coatings. Compared...
