Improved-hardness heat-radiation aqueous coating for glass doors, and its preparation method

Abstract

The invention discloses an improved-hardness heat-radiation 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, 2-4 parts of hexamethyldisiloxane, 18-22 parts of aqueous gadoleic acid resin, 1-2 parts of nanometer sericite powder, 1-2 parts of a pigment, 4-7 parts of inorganic nanometer ceramic resin, 1-2 parts of magnesium dialkyl sulfosuccinate, 0.3-0.4 parts of octadecanamide, 0.2-0.4 parts of polyether modified polysiloxane, 0.3-0.4 parts of azodiisobutyronitrile, 0.4-0.7 parts of sodium phytate, 0.5-1.0 part of a silane coupling agent KH792, 1-2 parts of triethanolamine borate, 0.6-1.2 parts of magnesium tungstate, 2-3 parts of nanometer charcoal powder, 1-2 parts of flake graphene, 0.3-0.6 parts of urea, 2-3 parts of diethylenetriamine and 13-16 parts of deionized water. The coating has the advantages of ageing resistance, strong adhesion, corrosion resistance, pollution resistance, fouling resistance, mutual coordination of the added nanopowders, good filling property, increase of the smoothness and the flatness of a coating film of the coating, and good heat radiation property.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a water-based coating for a heat-dissipating glass door with improved hardness 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...

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.
