Anti-stripping bacteriostatic waterborne coating for glass doors and preparation method thereof

Abstract

The invention discloses an anti-stripping bacteriostatic waterborne coating for glass doors. The coating is characterized by being prepared from the following raw materials in parts by weight: 23-26 parts of waterborne epoxy resin, 44-48 parts of waterborne amino acrylic resin, 1-2 parts of zinc powder, 0.4-0.7 part of monocrystalline silicon powder, 1-2 parts of elastic HDI (hexamethylene diisocyanate) curing agent E405-80T, 0.1-0.3 part of n-butyl phosphate defoaming agent, 0.3-0.6 part of white corundum powder, 0.2-0.4 part of potassium polyacrylate, 0.2-0.4 part of carrageenan, 0.1-0.3 part of organic silicon defoaming agent, 0.3-0.5 part of polyoxyethylene sorbitan monooleate, 0.5-1.0 part of silane coupling agent KH550, 1-3 parts of dipropylene glycol mono butyl ether, 3-5 parts of modified nano titanium dioxide photocatalyst, 1-2 parts of pigment, 2-3 parts of limonene, 2-4 parts of ethanol and 12-15 parts of deionized water. The added modified nano titanium dioxide photocatalyst can increase the functions of bacteriostasis, mildew resistance, air purification, deodorization, stain resistance, self cleanliness and the like for the coating; the added monocrystalline silicon powder can improve the hardness of the coating; the added zinc powder and white corundum powder have the performance of resisting rust, atmospheric corrosion, ageing and fire and the like; and therefore, the coating has the advantages of high adhesion, less stripping possibility, high hardness, abrasion resistance, good climate resistance, less ageing possibility, no toxicity and environmental friendliness, and can be widely applied to glass for household decoration and the like.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an anti-peeling and antibacterial water-based coating for 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...
