Abstract

The invention relates to the field of coating, in particular to a method for producing environment-friendly efficient electrophoretic paint. The environment-friendly efficient 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 and 15-20 parts of fillers. The method for producing the environment-friendly efficient electrophoretic paint includes steps of A, preparing the color paste; B, preparing the emulsion; C, preparing electrophoretic paint. The method has the advantages that the emulsion and the color paste are in different compound formulas when modified, and accordingly the environment-friendly efficient electrophoretic paint which is cathode electrophoretic paint is safe and is environmentally friendly.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environmentally friendly and efficient production method of 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...
