Abstract

The invention relates to the field of paint, in particular to corrosion-resistant low-temperature-curing cathode electrophoretic paint which comprises 1-2 parts of color paste, 4-6 parts of an emulsion and 5-7 parts of deionized water. The color paste comprises 20-30 parts of main resin, 5-10 parts of an alcohol-ether cosolvent, 3-8 parts of organic acid, 0.3-0.7 part of an emulsifier, 1-5 parts of a compound 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 compound regulator, 7-11 parts of a second compound regulator, 8-14 parts of a third compound regulator, 3-7 parts of a fourth compound regulator composed of polyacrylate-2-cross-linked polymer and corrosion-resistant liquid, and 15-20 parts of a filler, and the emulsion comprises 40-50 parts of modified epoxy resin A, 10-20 parts of modified epoxy resin B, 10-30 parts of a cross-linking agent, 5-9 parts of a curing agent, 3-8 parts of monomolecular amine, 0.1-2 parts of an emulsifier, 0.1-2 parts of a neutralizing agent and 30-50 parts of deionized water. Different compound formulations are used in the emulsion and the color paste in an improved, so that the cathode electrophoretic paint is corrosion-resistant, supportive of low-temperature curing and resistant to yellowing.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an anti-corrosion low-temperature curing 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 catho...
