Abstract

The invention relates to the technical field of paint and specifically relates to cathode electrophoresis paint suitable for a range hood and a preparation method thereof. The cathode electrophoresispaint suitable for the range hood is prepared from the following raw material ingredients in mass fraction: 10% to 20% of color paste, 30% to 50% of emulsion and 40% to 60% of pure water, wherein thecolor paste is prepared from the following ingredients in mass fraction: 10 to 35 parts of fluorine-modified epoxy resin, 5 to 15 parts of environment-friendly cosolvent, 1 to 6 parts of neutralizingagent, 0.1 to 0.5 part of surface active agent, 25 to 40 parts of pure water, 5 to 30 parts of kaolin and 4 to 20 parts of pigment; the emulsion is prepared from the following ingredient in mass fraction: 30 to 40 parts of fluorine-modified epoxy resin, 2 to 8 parts of emulsifying agent, 1 to 8 parts of neutralizing agent and 30 to 50 parts of pure water. The cathode electrophoresis paint suitablefor the range hood disclosed by the invention has the advantages of stronger throwing power, good chemical performance of water resistance and oil resistance and more environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a cathodic electrophoretic coating suitable for range hoods and a preparation method thereof. Background technique [0002] Since the advent of cathodic electrophoretic coatings, both the coating itself and the coating application technology have made a lot of progress, and many products and new application technologies have been introduced. So far, almost 100% of the automotive primers use cathodic electrophoretic coatings. [0003] Electrophoretic coatings are the first water-based coatings developed. Its main features are high coating efficiency, economy, safety, and low pollution, and it is convenient for automated large-scale production. After decades of development, the products have been constantly updated. The latest cathodic electrophoretic coatings require higher throwing power, lower P / B, better corner coverage and other characteristics. [0004] Most acrylic series ...
