Abstract

Disclosed are a cathode electrophoretic paint resin with high salt spray resistance and a preparation method thereof. Monomers adopted for the resin comprise monomers of methyl methacrylate, styrene,hydroxyethyl methacrylate, 2-(dimethylamino)ethyl methacrylate, butyl acrylate and phosphate; an initiator comprises azodiisobutyronitrile; a solvent is one or a mixture of more of isopropanol, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, ethyl acetate, butyl acetate, ethylene glycol monoethyl ether acetate and n-butyl alcohol; a neutralizing agent comprises one of formic acid, acetic acid and lactic acid. The solvent is loaded in a reactor, the initiator and the solvent are added for stirring, and heating is conducted to 80-100 DEG C; a mixture of the monomers and the initiator is added dropwise 1-5 times for 2-4 hours, and after dropwise addition, heat preservation is conducted for 0.5-2.5 hours at 80-100 DEG C; the remaining initiator is added for supplementation twice, and after heat preservation continues for 0.5-2.5 hours, the electrophoretic paint resin is obtained. The cathode electrophoretic paint resin has high salt spray resistance, the salt spray resistance of a paint film of the electrophoretic paint is greatly improved, and the quality of a product processed by the electrophoretic paint is further improved.

Description

technical field [0001] The invention relates to a cathodic electrophoretic paint resin, in particular to a cathodic electrophoretic paint resin with high salt spray resistance and a preparation method thereof. Background technique [0002] With the continuous enhancement of people's ecological awareness, the development and application of environmentally friendly materials have attracted more and more attention. As a green and environmentally friendly water-based electrophoretic coating, people have attracted widespread attention. The special resin for water-based electrophoretic coatings based on water-based acrylic resin has become one of the research hotspots. one. With the continuous expansion of the scope of application of cathodic electrophoretic coatings, electrophoretic coatings are also used for decorative products such as various household appliances, hardware and office supplies, etc., which have high requirements for appearance, especially in the metal surface tr...
