Abstract

The invention relates to the technical field of coatings, and particularly discloses a cathode electrophoretic coating applicable to grooved pipe fittings. The cathode electrophoretic coating is prepared from the following components in parts by weight: 10 to 20 parts of color paste, 30 to 60 parts of emulsion and 40 to 60 parts of pure water; the color paste is prepared from the following components in parts by weight: 10 to 35 parts of acrylate polyurethane modified epoxy resin, 5 to 15 parts of environmentally-friendly cosolvent, 1 to 6 parts of a neutralizer, 0.1 to 0.5 part of a surfactant, 25 to 40 parts of deionized water, 5 to 30 parts of kaolin and 3 to 23 parts of a pigment; the emulsion is prepared from the following components in parts by mass: 30 to 40 parts of acrylate polyurethane modified epoxy resin, 2 to 8 parts of an emulsifier, 1 to 8 parts of a neutralizer and 30 to 50 parts of pure water. The cathode electrophoretic coating provided by the invention is high in hardness, and is excellent in corrosion resistance, acid resistance, alkali resistance and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a cathodic electrophoretic coating suitable for grooved pipe fittings 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, the products have been constantly updated. The latest cathodic electrophoretic coatings require higher throwing power, lower P / B, better corner coverage and other characteristics. [0004] Most acryl...
