Problems solved by technology

[0009] At present, the most widely used radiation-type heat-insulating coatings are filled with metal oxides such as nano-antimony tin oxide, but they all have the disadvantages of high cost, low transparency, and poor antifouling performance. After a period of use, dust and dirt are easy to adhere to the paint. surface of the film, further reducing its transparency

Abstract

The invention provides a novel glass super-hydrophobic transparent efficient heat-insulating coating and a preparation method thereof, and relates to the field of building materials, in particular tothe novel glass super-hydrophobic transparent efficient heat-insulating coating. The novel glass super-hydrophobic transparent high-efficiency heat-insulating coating comprises the following raw materials by weight: 2400 to 2600 kg of aqueous fluorocarbon resin (with solid content of 45 to 50%), 1200 to 1300 kg of slurry, 1100 to 1300 kg of deionized water, 130 to 160 kg of a 1053 dispersant, 50 to 70 kg of a DP082 antifoaming agent, 30 to 50 kg of a WT102 thickener, 80 to 100 kg of texanol, 90 to 110 kg of leveling agent and 4 to 6 kg of dipropylene glycol. The method comprises: uniformly mixing the water-based fluorocarbon resin with the slurry in proportion, then adding deionized water, a dispersing agent, an antifoaming agent, a thickener, texanol, leveling agent, dipropylene glycol monomethyl ether and dipropylene glycol butyl ether, adjusting the pH value to 7, and dispersing in a dispersion machine at a high speed of 1500 rpm for 30 min to obtain the glass super-hydrophobic transparent efficient heat-insulating coating.

Description

[0001] The invention relates to the field of coatings. A novel glass super-hydrophobic transparent high-efficiency heat-insulating coating and a preparation method thereof. Background technique [0002] The sun's irradiation provides the necessary conditions for human survival and life, but the strong radiation of the sun in summer brings great inconvenience to human life and work. Thermal insulation paint is a new type of energy-saving decorative paint, which is used on the surface of buildings to reduce the internal temperature of buildings and reduce energy consumption such as air conditioning. [0003] The penetration rate of glass nano-transparent heat-insulating coatings in foreign countries is extremely high. In the United States, the penetration rate of architectural glass nano-transparent heat-insulating coatings has exceeded 90%. The penetration rate of nano-transparent heat-insulating coatings for architectural glass in Australia, New Zealand and other countries is...
