Abstract

The invention relates to the field of paints, and in particular, relates to a green environmental-protection cathode electrophoretic paint. The electrophoretic paint includes, by mass, 1-2 parts of color paste, 4-6 parts of an emulsion and 5-7 parts of deionized water; the electrophoretic paint color paste formula includes 20-30 parts of main resin, 5-10 parts of an alcohol ether co-solvent, 3-8 parts of an organic acid, 0.3-0.7 part of an emulsifier, 1-5 parts of a composite drier, 30-40 parts of deionized water, 3-7 parts of a first solid additive, 1.5-6 parts of a second solid additive, 6-9 parts of a first composite regulator and 15-20 parts of a filler; the first composite regulator is composed of methyltrioctylammonium bromide, glycerol and polytetrafluoroethylene according to the mass ratio of 1:(3-4):(1-2). Different compound formulas are improved and used in the emulsion and the color paste, and the cathode electrophoretic paint is green, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a green and environment-friendly cathodic electrophoretic coating. Background technique [0002] Since the advent of cathodic electrophoretic paint, because the formed paint film has excellent corrosion resistance and mechanical properties, and is suitable for automatic coating, it has quickly become popular in the automotive industry. The baking temperature range of traditional cathodic electrophoretic paint is generally 170 ~180°C. At present, many industrial workpieces are made of rubber, plastic and other materials, which are required to be dried together with electrophoretic paint after processing, so as to reduce the operating intensity of workers and control costs. However, such materials are easily deformed or melted when baked under high temperature conditions. In order to meet the needs of this type of process, there are very few varieties of low-temperature curing cathodic el...
