Anti-aging cathode electrophoretic coating with excellent throwing power and manufacture method thereof

Abstract

The invention discloses an anti-aging cathode electrophoretic coating with excellent throwing power. The coating is characterized by being prepared from the following raw materials in parts by weight: 28-33 parts of epoxy resin, 18-24 parts of melamine formaldehyde resin, 15-20 parts of pentalyn, 15-19 parts of glycerinum, 9-13 parts of cyanuric acid, 8-12 parts of styrene, 3-6 parts of methyl methacrylate, 4-7 parts of glycerol triacetate, 6-8 parts of mono methyl ethanol amine, 2-5 parts of dibutyltin dilaurate, 5-8 parts of polypropylene fibers, 0.1-0.3 part of nano-silver oxide, 10-14 parts of white carbon black, 2-5 parts of blast furnace slag, 0.4-0.8 part of magnesium sulfate, 12-15 parts of auxiliary, 16-19 parts of ethylene glycol monoethyl ether acetate, 9-11 parts of propylene glycol monomethyl ether and 75-85 parts of deionized water. According to the coating, polypropylene fibers, nano-silver oxide and other multiple materials are compounded together, the process flow and formula are optimized, the single function of the coating is improved, and the prepared cathode electrophoretic coating has diversified functions and has the advantages of low cost, excellent throwing power, excellent anti-aging performance, good construction and storage stability, acid and alkali resistance and the like; and a coated material by utilizing the coating has a new surface performance, so that higher requirements of people for coating performance can be met.

Description

technical field [0001] The invention relates to an electrophoretic paint, in particular to a cathodic electrophoretic paint with good throwing power and anti-aging and a preparation method thereof. Background technique [0002] Electrophoretic coatings and coating methods have been applied industrially since the 1960s. The use of electrophoretic coatings can operate in a fully closed cycle system, and the utilization rate of coatings can reach about 95% compared with conventional spraying. Electrophoretic coatings can be divided into anodic electrophoretic coatings and cathodic electrophoretic coatings according to the electrodes of the coated workpieces. At present, cathodic electrophoretic coatings are the most widely used, which use water-soluble or water-dispersible ionic polymers as film-forming materials, and the coated workpieces are used as cathodes. , a new type of low-pollution, energy-saving, resource-saving, protective and anti-corrosion coating applied by electr...
