Abstract

The invention relates to the field of coating, in particular to environment-friendly compound cathode electrophoretic paint. The environment-friendly compound cathode electrophoretic paint comprises 1-2 parts of color paste, 4-6 parts of emulsion and 5-7 parts of deionized water. The color paste in a formula comprises 20-30 parts of matrix resin, 5-10 parts of alcohol ether complex solubilizers, 3-8 parts of organic acid, 0.3-0.7 part of emulsifiers, 1-5 parts of compound driers, 30-40 parts of deionized water, 3-7 parts of first solid additives, 1.5-6 parts of second solid additives, 6-9 parts of first compound modifiers, 7-11 parts of second compound modifiers, 8-14 parts of third compound modifiers, 3-7 parts of fourth compound modifiers, 4-8 parts of flame retardants and 15-20 parts of fillers, the fourth compound modifiers comprise polyacrylate-2-cross-linked polymers and preservative solution which are matched with one another according to a mass ratio of 1:1-4, and the flame retardants comprise ammonium pyrophosphate, boric acid and melamine cyanurate which are matched with one another according to a mass ratio of 1:2-3:1-4. The environment-friendly compound cathode electrophoretic paint has the advantages that the emulsion and the color paste are in different compound formulas when modified, and accordingly the environment-friendly compound cathode electrophoretic paint is flame-retardant and yellowing-resistant and can be cured at low temperatures.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environment-friendly composite cathodic electrophoretic paint. 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 ele...
