Abstract

The invention discloses a formula of high-performance self-crosslinking acrylic resin environmental-friendly cathode electrophoretic paint. The formula of the cathode electrophoretic paint comprises the following raw materials in parts by weight: 15-25 parts of acrylic resin, 0.3-1 part of a neutralizer, 0.1-0.2 part of an environmental-friendly catalyst, 0.1-0.5 part of a film-forming agent, 1-2parts of color paste and 60-70 parts of deionized water. Synthetic raw materials of the acrylic resin comprise monomers, an initiator and a solvent; the initiator comprises 1-3 parts of azodiisobutyronitrile; the solvent comprises one or more of isopropanol, glycol ethylene ether, butyl cellosolve, ethyl acetate, n-butyl acetate and ethoxyethyl acetate; the environmental-friendly catalyst comprises one or a complex of two of bismuth isooctoate and yttrium naphthenate. The invention further provides a preparation method. The cathode electrophoretic paint which has high gloss and of which the hardness and film thickness can meet user requirements can be prepared, VOC in the paint can be effectively reduced, and the load of the paint on the environment is alleviated.

Description

technical field [0001] The invention relates to the technical field of cathodic electrophoretic paint, in particular to a high-performance self-crosslinking acrylic resin environment-friendly cathodic electrophoretic paint and a preparation method. Background technique [0002] With the development of society, the requirements for volatile organic compounds (VOC) in countries around the world are becoming more and more stringent. Water-based coatings have been widely used due to their advantages such as non-toxic, environmentally friendly, odorless, low VOC content, and non-flammable and explosive. Among them, electrophoretic coating has been widely used in various fields due to its good adhesion, high hardness, strong wear resistance, good chemical resistance and excellent impact resistance, and has developed into a very important variety in the coating field. [0003] In electrophoretic coatings, compared with anodic electrophoretic coatings, cathodic electrophoretic coati...
