Water and corrosion resistant quick-drying aqueous coating for glass doors, and its preparation method

Abstract

The invention discloses a water and corrosion resistant quick-drying aqueous coating for glass doors. The coating is prepared by using the following raw materials, by weight, 30-34 parts of aqueous hydroxyl acrylic resin, 7-9 parts of an aqueous film forming agent, 2-3 parts of methyldichlorosilane, 12-14 parts of aqueous phenolic epoxy resin, 13-15 parts of a polyimide emulsion, 1-2 parts of ceramic powder, 0.5-1.0 part of a silane coupling agent KH602, 0.2-0.4 parts of dimethyl silicone oil, 0.2-0.4 parts of liquid paraffin, 2-3 parts of diethylene glycol butyl ether, 2-4 parts of 2-phenoxyethyl acrylate, 1-2 parts of activated rubber powder, 0.3-0.5 parts of bisethyl phenol polyoxyethylene ether, 0.6-1.2 parts of rare earth nitrate, 2-3 parts of diethylenetriamine, 1-3 parts of a pigment, 2-3 parts of alpha-terpineol, 0.2-0.3 parts of oleic acid triethanolamine and 13-16 parts of deionized water. The aqueous glass coating has the advantages of quick drying speed, water resistance, ageing resistance, corrosion resistance and environmental protection, and can be widely used in household glass decoration.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a water-based coating for waterproof, corrosion-resistant and quick-drying glass doors and a preparation method thereof. Background technique [0002] The emergence of glass communicates the boundaries between indoors and outdoors, space and space, making a revolutionary leap in home design. The current coating technology has endowed glass with more artistry and functionality. Although the existing glass coatings can meet people's needs to a certain extent, most of the glass coatings sold on the market are oily coatings, and their film-forming substances mainly come from petrochemical products, and their solvents are mostly organic solvents, which often contain formaldehyde, Toxic substances such as free TDI and xylene, these substances are continuously emitted during the production and use of glass coatings, which not only cause environmental pollution, but also dam...

Although the existing glass coatings can meet people's needs to a certain extent, most of the glass coatings sold on the market are oily coatings, and their film-forming substances mainly come from petrochemical products, and their solvents are mostly organic solvents, which often contain formaldehyde, Toxic substances such as free TDI and xylene, these substances are continuously emitted during the production and use of glass coatings, which not only cause environmental pollution, but also damage human health; compared with traditional solvent-based coatings, water-based coatings are low in price and easy to use. Safety, saving resources and energy, reducing environmental pollution and public hazards have become the main direction of the current development of the coatings industry. Therefore, the development of glass coatings from solvent-based to water-based is an inevitable trend to meet the requirements of green environmental protection, and with the application The continuous expansion of the field has put forward higher and higher requirements for the functional characteristics of glass coatings, which have far exceeded the requirements of traditional decoration and beautification.
