Abstract

The invention relates to the technical field of coatings and particularly discloses a cathodic electrophoretic coating and a preparation method thereof. The coating comprises components in parts by weight as follows: 10-20 parts of color paste, 30-60 parts of an emulsion and 40-60 parts of deionized water. The color paste comprises components in parts by weight as follows: 18-35 parts of modifiedresin, 5-15 parts of an environment-friendly cosolvent, 1-6 parts of a neutralizer, 0.1-0.5 parts of a surfactant, 30-40 parts of deionized water and 20-30 parts of pigment and filler. The emulsion comprises components in parts by weight as follows: 35-50 parts of modified resin, 2-8 parts of an emulsifier, 1-8 parts of a neutralizer and 30-50 deionized water. The cathodic electrophoretic coatinghas good gloss and high hardness and adhesion and has excellent impact resistance, corrosion resistance, acid resistance, base resistance and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a cathodic electrophoretic coating and a preparation method thereof. Background technique [0002] Since the advent of cathodic electrophoretic coatings, both the coating itself and the coating application technology have made a lot of progress, and many products and new application technologies have been introduced. So far, almost 100% of the automotive primers use cathodic electrophoretic coatings. [0003] Electrophoretic coatings are the first water-based coatings developed. Its main features are high coating efficiency, economy, safety, and low pollution, and it is convenient for automated large-scale production. After decades of development, products have been constantly updated, and market demand has become increasingly demanding. Electrophoretic coatings are required to have higher throwing power, lower P / B, and better corner coverage. However, at present Current cathod...
