Abstract

The invention relates to the technical field of coatings and particularly discloses a cathode electrophoretic coating with high throwing power and a preparation method of the cathode electrophoretic coating. The cathode electrophoretic coating comprises the following raw materials in parts by weight: 5-15 parts of color paste, 35-70 parts of emulsion and 30-50 parts of deionized water, wherein thecolor paste is prepared from components in parts by mass as follows: 5-30 parts of organosilicone modified acrylic resin, 5-20 parts of an environment-friendly cosolvent, 2-7 parts of a neutralizer,0.1-1 part of a surfactant, 20-45 parts of deionized water, 3-27 parts of kaolin and 5-25 parts of pigment; the emulsion is prepared from components in parts by mass as follows: 30-40 parts of organosilicone modified acrylic resin, 3-9 parts of an emulsifier, 2-10 parts of a neutralizer and 25-45 parts of deionized water. The prepared cathode electrophoretic coating can meet the requirement for workpiece surface coating of metal building materials, and a film layer with uniform thickness can be obtained at a gap or a shielded part of a coated workpiece.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a cathodic electrophoretic coating with high throwing power 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] Metal building mater...
