Bacteriostasis, sterilization and air purification type aqueous coating for glass doors, and its preparation method

Abstract

The invention discloses a bacteriostasis, sterilization and air purification type aqueous coating for glass doors. The coating is prepared by using the following raw materials, by weight, 30-34 parts of aqueous hydroxy acrylic resin, 7-9 parts of an aqueous film forming assistant, 13-15 parts of an organosilicon polyester resin emulsion, 12-14 parts of aqueous polyurethane resin, 0.6-1.2 parts of methyltrimethoxysilane, 0.7-1.3 parts of tributyl citrate, 1-2 parts of selenious nitrate, 0.2-0.3 parts of rare earth chloride, 0.3-0.5 parts of rosin-polythylene oxide ester, 2-3 parts of dipropylene glycol monomethyl ether, 1-2 parts of polytetrafluoroethylene, 2-3 parts of m-phenylenediamine, 1-2 parts of a pigment, 1-3 parts of N-methyldiethanolamine, 1-2 parts of activated clay, 1-3 parts of alpha-cyanoacrylate, 2-4 parts of chitosan fiber, 0.3-0.4 parts of propoxylated lanolin alcohol, 1-2 parts of sodium citrate and 13-16 parts of deionized water. The aqueous coating for glass has the advantages of excellent performances, substantial sterilization and mildew prevention effects, air purification, environmental protection, and suitableness for popularization.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a water-based paint for antibacterial, sterilizing and air-purifying 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 damage huma...

Problems solved by technology

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.
