[0022]Mix tetrabutyl titanate and absolute ethanol at a molar ratio of 9:2, add them to the reaction kettle, and stir at a speed of 200r / min to obtain a titanium alkoxide sol, and then mix the titanium alkoxide sol and water molar Mix at a ratio of 25:3, adjust the pH of the solution to 3 with hydrochloric acid with a concentration of 0.5mol / L, and react for 30 minutes to obtain a titanium dioxide sol; mix the above titanium dioxide sol and phenol at a molar ratio of 4:1 to obtain a mixture, and then mix the mixture Mix with n-heptane in an equal mass ratio to obtain a pre-reaction solution. While stirring, continue to drop 10% of the mass of the pre-reaction solution into the reaction kettle with a concentration of 1mol / L formaldehyde solution, and let it stand at 80°C for 1.5h. Obtain the pre-product, then put the pre-product in a muffle furnace, and roast it at a temperature of 500° C. for 2 hours to obtain porous spherical nanocrystals of titanium dioxide; add 80 parts of d...

Abstract

The invention relates to a preparation method of an aqueous transparent heat-insulating glass coating, and belongs to the technical field of preparation of architectural coatings. Modified polytetrafluoroethylene resin is creatively used as a matrix, and nano titanium dioxide is used as filler so as to prepare the glass coating, wherein the polytetrafluoroethylene resin which is modified by an adhesion promoter has ultra-high adhesion so that the performance of the aqueous transparent heat-insulating glass coating is more comprehensive, and organic pollutants adsorbed on the surface of the nano titanium dioxide are decomposed into carbon dioxide and oxygen through selection of the nano titanium dioxide as the filler, so that the original brightness of glass is maintained, and a good heat insulating effect is achieved without influence on the transparency of the glass. The aqueous transparent heat-insulating glass coating has the advantages of strong adhesion, long service life, good water resistance, strong viscosity resistance, strong anti-staining performance, strong UV resistance, high transparency and a good thermal insulation effect, formaldehyde and other indoor harmful organic compounds can be decomposed, and therefore the coating has a very broad application prospect and advantage.

Description

technical field [0001] The invention relates to a preparation method of a water-based transparent heat-insulating glass paint, which belongs to the technical field of architectural paint preparation. Background technique [0002] Glass coating is a kind of coating. The glass surface is usually very smooth. Ordinary coatings are difficult to adhere to the glass surface. Good glass coatings form a stable and hard paint film on the glass surface, which will show high transparency and high gloss in appearance. specialty. In construction, the viscosity is usually low, and at the same time, it will not cause sagging. It can be stably adhered to the surface of glassware, and it can beautify and decorate glassware through different colors. Because glass does not have a good performance of insulating heat radiation, the problem of high energy consumption caused by its application in buildings or structures or other fields has attracted a lot of attention. In particular, thousands ...
