Whitening and anti-aging aqueous coating for glass sliding doors and preparation method of whitening and anti-aging aqueous coating

Abstract

The invention discloses a whitening and anti-aging aqueous coating for glass sliding doors. The whitening and anti-aging aqueous coating is characterized by being prepared from the following raw materials in parts by weight: 40-50 parts of aqueous polyurethane resin, 15-20 parts of an E-20 epoxy resin emulsion, 7-10 parts of a modified pure acrylic emulsion, 2-3 parts of nano-calcium carbonate, 1-3 parts of dipropylene glycol dimethyl ether, 0.3-0.6 part of alcoholamine diphosphoryloxy glycolic acid titanate, 0.2-0.4 part of fluoro-alkyl polyether modified polysiloxane, 0.5-1.0 part of alkylaryl polyether alcohol, 0.2-0.4 part of dimethicone, 0.3-0.6 part of propyl trimethoxy siloxane, 0.3-0.5 part of nano-montmorillonite, 0.4-0.7 part of vermiculite powder, 0.3-0.4 part of aluminum tripolyphosphate, 0.4-0.8 part of high-gloss powder, 1-2 parts of brightening titanium dioxide and 10-15 parts of deionized water. The aqueous glass coating disclosed by the invention is simple in preparation method, good in adhesion against a glass substrate and high in aging resistance; by adding the brightening titanium dioxide and the high-gloss powder, the brightness is improved; the added modified pure acrylic emulsion has the characteristics of excellent stain resistance, bactericidal property, scrub resistance, weather resistance and the like; and the coating disclosed by the invention is fast in drying speed and a paint film is smooth.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a whitening and aging-resistant water-based coating for glass sliding doors and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the pursuit of beauty is also more intense. Colored glass coatings meet the needs of the market with their unique bright and colorful decorative effects. Glass coatings have good adhesion and can be coated on wine bottles, The surface of daily-use glass products such as perfume bottles, lighting glass, art glass, etc., makes it colorful. However, the existing glass coatings are two-component coatings, which need to be deployed on the spot. After the deployment, they must be used in a short time, otherwise they will become invalid, which is not only inconvenient to use, but also easily causes waste of materials; Most of the glass coatings sold are oil-based coatings, an...

Problems solved by technology

However, the existing glass coatings are two-component coatings, which need to be deployed on the spot. After the deployment, they must be used in a short time, otherwise they will become invalid, which is not only inconvenient to use, but also easily causes waste of materials; Most of the glass coatings sold are oil-based coatings, and their solvents are mostly organic solvents, which often contain toxic substances such as formaldehyde, free TDI and tributyl dicitrate. These substances are continuously emitted during the production and use of glass coatings. Cause environmental pollution and damage human health
