Embodiment 1

[0034] Weigh 1.5g sodium polyphosphate and add it to 80ml distilled water, add 10g ATO powder, 5g TiO 2 Powder. And adjust the pH of the system to 8. After stirring evenly, ultrasonically disperse for 15 minutes, and then stir on the FJ200 high-speed homogeneous disperser for 4 hours. Get ATO-TiO 2 The composite slurry has good dispersion stability, and no significant settlement has occurred after a long period of storage. Weigh 110g of water-based polyurethane (PUD-350, Shanghai Sisheng), and mix it with ATO-TiO 2 Mix the composite slurry evenly, add 1.5g of dispersant (Shenzhen Shuangcheng Trading Company, FT-206), 0.8g of sodium polyacrylate and 1.0g of methyl cellulose in sequence, then stir on a high-speed homogeneous disperser for 2 hours to obtain a coating, and then The paint is applied to the glass in a dipping-pulling method to obtain a uniformly coated and uniform heat-insulating self-cleaning glass film.

Embodiment 2

[0036] Weigh 2.5g sodium hexametaphosphate and add it to 100ml distilled water, stir rapidly and add 15g nano-ATO powder, 10g TiO 2 Powder. After adjusting the pH=6, ultrasonically disperse for 15 minutes, and then stir for 4 hours by a shear emulsification mixer. Get ATO-TiO 2 The composite slurry has good dispersion stability, and no significant settlement has occurred after a long period of storage. Weigh 150g of water-based polyurethane (PUD-350, Shanghai Sisheng), and mix it with ATO-TiO 2 Mix the composite slurry evenly, add 2.5g dispersant (FT-206), 1.4g polyether organosiloxane leveling agent (Shenzhen Shuangcheng Trading Company FL-3) and 1.6g methylcellulose in sequence, and then high-speed Disperse for 2 hours to obtain the coating, and then apply the coating to the glass by means of suspension coating to obtain a heat-insulating self-cleaning glass film with uniform coating and uniform film quality.

Embodiment 3

[0038] Weigh 12g nano ATO powder, 5g TiO 2 Powder and 1.5g sodium dodecylbenzenesulfonate. Add it into 90ml of distilled water, stir evenly, adjust the pH of the system to 8, then stir at high speed for 4~5h, and finally ultrasonically disperse for 15min. Get ATO-TiO 2 The composite slurry has good dispersion stability, and no significant settlement has occurred after a long period of storage. Weigh 200g of bisphenol-A type epoxy resin (EP 01661-310), mix it with the composite slurry, add 2.0g of dispersant (FT-206), 1.5g of polyether organosiloxane leveling (FL-3) and 1.8g of methyl cellulose, and then stirred at high speed for 2 hours to obtain the coating, which was coated on the glass by dipping and pulling to obtain a heat-insulating self-cleaning glass film with uniform coating and uniform film quality.

Abstract

The invention discloses a glass coating with heat-insulating and self-cleaning functions, mainly comprising the following components: a film-forming resin, nano antimony-doped tin oxide (ATO) powder, nano TiO2 powder, a dispersing agent, film-forming additives and the like. Coated by the glass coating, the glass has dual heat-insulating and self-cleaning functions. The energy is saved and the manual wiping work is reduced due to the adoption of the glass coating. In addition, the glass coating is easy to prepare, low in cost and suitable for industrial production.

Description

technical field [0001] The invention relates to a thermal insulation self-cleaning paint for glass. Background technique [0002] With the development of society and the improvement of productivity, people's demand for energy is increasing, and various environmental problems caused by a large amount of energy release, such as the greenhouse effect and acid rain, are also increasingly concerned by the whole society. In many countries, the energy consumption of refrigeration equipment such as air-conditioning fans accounts for more than 20% of the total annual energy consumption, and the energy consumption of buildings accounts for about 30%-40% of the world's energy consumption. Therefore, people put forward higher requirements for building energy saving and environmental protection. [0003] Since 40%-50% of heating and air-conditioning energy consumption is caused by the heat transfer of doors and windows, and modern buildings and automobiles widely use large-area glass wi...
