Aqueous transparent heat insulation coating for glass doors, and its preparation method

Abstract

The invention discloses an aqueous transparent heat insulation 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, 0.5-0.7 parts of hexamethyldisilazane, 12-15 parts of a fluorocarbon emulsion, 9-13 parts of an aqueous self-crosslinked acrylic emulsion, 1-2 parts of precipitated barium sulfate, 1-2 parts of a carbon fiber, 0.3-0.4 parts of polyoxyethylene isooctyl ether, 2-3 parts of dipropylene glycol dimethyl ether, 0.2-0.5 parts of polyether modified polysiloxane, 2-3 parts of paraffin oil, 0.3-0.5 parts of polyoxyethylene monopalmitate, 0.6-0.8 parts of a silane coupling agent KH602, 2-3 parts of triethylenetetramine, 2-3 parts of tripropylene glycol diacrylate, 0.4-1.0 part of N-phenyl-N'-cyclohexyl-p-phenylenediamine, 1-3 parts of an aqueous metal complexing dye and 13-16 parts of deionized water. The coating has the advantages of excellent film forming performance, transparent color, ageing resistance, strong adhesion, corrosion resistance, contamination resistance and excellent heat insulation performance, and can be widely used in household glass decoration.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a water-based transparent heat-insulating glass door paint 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 human health; compared wit...

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.
