Embodiment 1

[0028] A preparation method for thermal insulation coating for architectural glass, comprising the steps of:

[0029] The first step is to prepare ATO alcohol slurry:

[0030] Put the ATO powder with a particle size of 5-50nm into absolute ethanol, stir evenly, add BYK180 dispersant, stir again, add cationic polyacrylamide, and then adjust the pH to 9 with a pH regulator (sodium hydroxide or hydrochloric acid) After stirring evenly, ultrasonically disperse for 10 minutes, then disperse with a high-speed disperser for 100 minutes, and finally disperse with a ball mill for 100 minutes. The weight percentage of ATO in the obtained alcohol slurry is 10%, the weight percentage of BYK180 dispersant is 2.5%, and the weight percentage of polyacrylamide The percentage is 0.5%;

[0031] The second step is to prepare ATO thermal insulation coating:

[0032] Add the ATO alcohol slurry obtained in the first step into polyvinyl butyral and add coating additives, mix and stir evenly. The w...

Abstract

The invention proposes a method for preparing thermal insulation coatings for architectural glass, comprising: preparing ATO alcohol slurry: putting ATO powder into an alcoholic solvent, stirring evenly, adding a polymer cationic dispersant, stirring again evenly, adding Cationic surfactant, then use a pH regulator to adjust the pH to 9, and then use ultrasonic dispersion, high-speed disperser dispersion and ball mill dispersion to carry out staged dispersion after stirring evenly, and the weight percentage of ATO in the obtained alcohol slurry is 10-30% , the weight percentage of polymeric cationic dispersant is 2.5-6%, and the weight percentage of cationic surfactant is 0.5-3%; Add alcoholic resin and coating auxiliary agent to prepare ATO thermal insulation coating afterwards, final product is environment-friendly insulation Thermal coating has good dispersibility, high stability, uniform film formation, and better heat insulation effect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermal insulation coating for architectural glass and a preparation method thereof. Background technique [0002] With the development of the construction industry, building energy efficiency has been paid more and more attention. Among the four enclosure components of doors, windows, walls, roof, and ground that affect building energy consumption, doors and windows have the worst thermal insulation performance, which is one of the important factors affecting indoor thermal environment comfort and building energy consumption. As the main component of the door frame, the glass has poor heat insulation effect, which is the main reason for the energy loss of buildings. [0003] Patent: A high-performance thermal insulation coating and its preparation method (application number 201110157311.5) provides thermal insulation coatings with the following component weight ratios: film-...
