Abstract

The invention discloses a heat-insulating glass coating and a preparation method thereof. The heat-insulating glass coating disclosed by the invention comprises the following components in parts by mass: 15-20 parts of deionized water, 0.3-0.6 part of defoaming agent, 30-60 parts of nanometer dispersion liquid, 0.6-1 part of thickening agent and 35-55 parts of fluorine-modified organic silicon resin. The heat-insulating glass coating has the advantages that the optical properties of glass are not affected due to high light transparency; sunlight energy is effectively insulated due to high heatinsulation property; and the ultraviolet insulation rate is high.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-insulating glass coating and a preparation method thereof. Background technique [0002] At present, my country's building energy consumption is twice as high as that of western developed countries. With the tight supply of oil and coal, prices continue to rise, and energy supply is getting tighter. The country attaches great importance to energy conservation and emission reduction, and vigorously promotes and develops energy-saving products. According to statistics, the energy consumption lost through buildings in my country accounts for 40% of the total energy consumption, while the energy lost through doors and windows is about 46%. If heat insulation coating products are used for the glass of doors and windows, the glass can be selectively transparent to light. On the premise that it can pass through visible light without affecting the lighting, it can shield infrared ...
