Abstract

The invention relates to the technical field of electrophoresis paint, and particularly discloses cathode electrophoresis paint and a production method thereof. The paint comprises the following components in parts by weight: 10-15 parts of mill base, 40-50 parts of an emulsion and 50-60 parts of deionized water; the emulsion comprises the following components: epoxy-amine-polyurethane resin, organic silicon resin, an emulsifier, deionized water, a neutralizer, a cosolvent and a sterilizing agent; and the mill base comprises the following components: epoxy-amine-polyurethane resin, deionized water, organobentonite, pigment, catalytic slurry and a neutralizer. The produced cathode electrophoresis paint is high in hardness, high in adhesion and high in flexibility, and has excellent corrosion resistance and oil resistance, and throwing power of the cathode electrophoresis paint reaches 0.7 or above.

Description

Technical field [0001] The invention relates to the technical field of electrophoretic coatings, in particular to a cathodic electrophoretic coating and a preparation method thereof. Background technique [0002] Electrophoretic paint is an environmentally friendly paint. It uses water as a solvent, has low volatile organic compounds (VOC) and harmful air pollutants (HAP), and has relatively little pollution to the environment. According to the different polarity of the water-soluble film-forming material after the electrophoretic coating is dissociated in water, it can be divided into two types: anode electrophoretic coating and cathodic electrophoretic coating. Anodic electrophoretic coatings have the disadvantage of anodic oxidation, which will corrode metal surfaces (except aluminum and inactive metals) and make them lose their luster. Therefore, anodic electrophoretic coatings are generally only used as anticorrosive primers and cannot meet the requirements of surface decora...
