Problems solved by technology

The heat-reflective film attached to the glass surface can ensure a certain amount of visible light through the room, and has high reflectivity of infrared rays. In the hot summer, it can ensure that the indoor temperature will not rise too high, which can save air conditioning electricity costs. rate is greatly affected, and there is also the problem of light pollution
Water-based transparent coatings have disadvantages such as poor stain resistance, not easy to clean, and easy to stick to water

Abstract

The invention relates to a transparent, hydrophobic and heat-insulating coating material for glass and a preparation method thereof. The coating material comprises water, a defoamer FL-12, a dispersant KS-82, a wetting agent FB-111, a water-based acrylic emulsion AC-261P, mixed resin, a thickener 8088, SiO2 nano-powder, antimony-tin oxide (ATO) doped nano-powder, polyether modified silicone oil and the like. The preparation method comprises two steps: (1) preparing a non-settling nano-powder dispersion of ATO doped nano-powder and SiO2 nano-powder; (2) adding the polyether modified silicone oil, the water-based acrylic emulsion AC-261P and the mixed resin into water, pouring the prepared nano-powder dispersion, adding the thickener 8088, and thoroughly stirring, thereby obtaining the coating material. During use, the prepared coating material is coated on the glass through spraying and then is dried. The coating material can be extensively applied to the glass of buildings, and has the long-term advantages of building energy saving, self cleaning and attractiveness.

Description

technical field [0001] The invention relates to a functional coating, and further relates to a formula and a preparation method of an energy-saving and environment-friendly transparent coating for glass. Background technique [0002] With the acceleration of global industrialization and urbanization, and with the continuous improvement of living standards, the world's energy consumption is increasing, especially in emerging economies, the demand for energy is accelerating. At present, energy mainly comes from oil, natural gas, coal, wind power, solar energy, hydropower and nuclear power. With the rapid development of new energy and the maturity of technology, the proportion of clean energy such as wind power, solar energy, hydropower, and nuclear power is getting higher and higher. At present, non-renewable energy such as oil, coal, and natural gas still accounts for more than 70%, automobile petroleum energy consumption accounts for 40%~50% of it, and building energy consu...
