Abstract

The invention belongs to the field of aqueous paint, and especially relates to a wear-resistant cathode electrophoresis coating, and a preparation method thereof. The wear-resistant cathode electrophoresis coating comprises a color paste, an emulsion, and water; the color paste comprises a polytetrafluoroethylene fluororesin, a cosolvent, a neutralizer A, a surfactant, deionized water, kaolin, anda pigment filler; the emulsion comprises a trifluoroethyl methacrylate fluororesin, an emulsifier, a neutralizer B, and deionized water. The wear-resistant cathode electrophoresis coating possesses excellent throwing power, is high in hardness, clunging force, acid and alkali resistance, wear resistance, corrosion resistance, paint film uniformity, and glossiness.

Description

technical field [0001] The invention relates to the field of water-based coatings, in particular to a wear-resistant cathodic electrophoretic coating and a preparation method thereof. Background technique [0002] Cathodic electrophoretic paint is an environmentally friendly paint used for primers improved on the basis of water-based dipping primers. It has the advantages of high painting efficiency, economy, safety, and less pollution, and is convenient for automated scale production. Common cathodic electrophoretic coatings include epoxy resin coatings, alkyd resin coatings, amino resin coatings, phenolic resin coatings, and the like. At present, more than 95% of automotive primers are cathodic electrophoretic coatings. In addition, the protection of building materials, light industry, household appliances and hardware and other industrial fields all use cathodic electrophoretic coatings as the development direction. As a primer, the cathodic electrophoretic coating needs...
