Heat-insulating and mildew-resistant water-based paint for glass door and preparation method of water-based paint

Abstract

The invention discloses a heat-insulating and mildew-resistant water-based paint for a glass door. The water-based paint is characterized by being prepared from the following raw materials in parts by weight: 23-26 parts of an epoxy resin emulsion, 40-45 parts of water-based amino-alkyd resin, 0.3-0.5 part of a flatting agent BYK-307, 1-2 parts of zinc powder, 0.5-1.0 part of a silane coupling agent NQ-71, 0.2-0.3 part of nanometer ground calcium carbonate, 0.2-0.4 part of a polyacrylate thickener, 0.4-0.7 part of hollow glass powder, 0.2-0.3 part of polyoxyethylene monoleate, 0.3-0.5 part of ceramic powder microsphere, 0.1-0.3 part of polymeric microspheres, 0.2-0.4 part of sodium diacetate, 2-3 parts of butyl carbitol, 0.2-0.4 part of liquid paraffin, 2-3 parts of ethylene glycol monobutyl ether, 0.1-0.3 part of fatty acid polyethylene glycol ester, 3-5 parts of a modified nanometer titanium dioxide photocatalyst, 1-2 parts of a pigment and 12-15 parts of deionized water. The added modified titanium dioxide photocatalyst has the functions of effectively purifying air, removing stink and odor, killing a plurality of bacteria and preventing mildew; a good thermal insulation effect is achieved by combined action of added hollow glass powder, ceramic powder microspheres and polymeric microspheres; the production cost of the paint is reduced; and the paint disclosed by the invention is excellent in various performances, does not contain a special odor, is safe and non-toxic, and can be widely applied to glass for home decoration.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a water-based coating for heat-insulating and mildew-proof 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 r...

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
