Problems solved by technology

However, the scratch resistance of this material is not good, so it cannot be used as an antibacterial material for a long time, and it is easy to fall off during long-term use
[0004] Chinese patent CN101215438A discloses an anti-fouling and anti-aging stainless steel coating and its preparation method. The coating is formed by mixing acrylic resin, film former, filler, solvent and auxiliary agent, wherein the film former includes fluororesin, water-based polyurethane, Epoxy resin, the filler contains nano-silica, the prepared coating has good aging resistance and UV resistance, but its scratch resistance is not good, which affects its service life and comprehensive performance

Abstract

The invention discloses a weather-resistant and antibacterial steel surface coating material and a preparation method thereof. The weather-resistant and antibacterial steel surface coating material is prepared from the following components in parts by weight: 25-39 parts of polyacrylamide, 8-14 parts of vinyl versatate, 0.5-1.2 parts of polylysine, 0.05-0.08 part of dibutyltin maleate, 0.8-1 part of sodium bicarbonate, 0.01-0.2 part of antioxygen, 11-17 parts of propylene glycol monomethyl ether and 100-110 parts of water. The invention further provides the preparation method of the weather-resistant and antibacterial steel surface coating material. The weather-resistant and antibacterial steel surface coating material prepared by the invention can be widely applied to the surfaces of household electrical appliances, instruments, meters, air purification equipment and water purification equipment.

Description

technical field [0001] The invention belongs to the field of coating materials, in particular to a weather-resistant and antibacterial steel surface coating material and a preparation method thereof. Background technique [0002] Steel surface coating is a coating material used on the surface of steel materials to change the characteristics of the steel surface. The steel surface coating material can play a good role in protecting the steel surface, and by adding color paste materials, it can change the color and play a decorative effect. At the same time, the coating material on the steel surface can improve the surface tension of the steel and play the role of isolating the air, reducing the oxidation rate of the steel surface and increasing the service life of the material. [0003] Chinese patent CN101180372A discloses a corrosion-resistant antibacterial resin composition, which can be used on the surface of steel plates. It mainly includes acrylic resin, polyurethane ...
