Antibacterial and scrubbing-resistant waterborne coating for glass door and preparation method of waterborne coating

Abstract

The invention discloses an antibacterial and scrubbing-resistant waterborne coating for a glass door. The waterborne coating is characterized by being prepared from the following raw materials in parts by weight: 34-37 parts of waterborne epoxy emulsion, 13-15 parts of waterborne organosilicone emulsion, 20-24 parts of vinyl acetate / butyl acrylate emulsion, 2-4 parts of triethylene glycol monoethyl ether, 0.3-0.6 part of alkanolamine alkoxy titanate, 0.3-0.5 part of a flatting agent BYK-310, 0.1-0.2 part of nanobacteria cellulose, 0.2-0.4 part of white oil, 0.5-1.0 part of polyethylene glycol methacrylate, 0.4-0.6 part of tetrachloro isophthalonitrile, 0.3-0.5 part of fatty acid polyoxyethylene ether, 0.4-0.7 part of citral, 0.2-0.4 part of cuprous oxide, 3-5 parts of a modified titanium dioxide photocatalyst, 1-2 parts of pigment and 10-15 parts of deionized water. The coating for the glass door has the advantages of excellent water resistance, high hardness, scrubbing resistance and low film forming temperature as well as excellent performance, low cost, strong adhesion after curing and no peeling and is non-toxic and environmentally friendly; by adding a plurality of organic, inorganic, and natural antibacterial agents, the antibacterial property of the coating is enhanced; and by adding modified titanium dioxide photocatalyst, the air can be effectively purified, bacteria can be killed and the deodorant effect, taste removal effect, antifouling effect and the self-cleaning function are achieved.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a water-based paint for sterilizing and scrubbing-resistant glass doors and a preparation method thereof. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. Water-based coatings use water as the dispersion medium, and only use a small amount of low-toxic alcohol ether organic solvents, which are safe and environmentally friendly, save resources, eliminate the risk of fire during construction, and help reduce air pollution. Water-based paint has very good adaptability to the surface of the material, and it can also be applied in a humid environment, and the coating has strong adhesion. Glass and glass products need to be coated with coatings due to the needs of aesthetics and performance. The development of glass coatings from solvent-based to water-based is an inevitable trend to meet the re...

Problems solved by technology

However, if the nano-titanium dioxide photocatalyst is poorly dispersed in the product, it will cause agglomeration

This kind of agglomeration will directly affect the photocatalyst activity, reduce the photocatalytic ability of the product, and then lose the pollution degradation effect
