Abstract

The invention discloses a double-component waterborne polyurethane glass transparent insulating coating, which comprises acrylate dispersion, a polyurethane curing agent, nano ATO aqueous solution, a thickening agent, a film-forming aid, and other aids. The double-component waterborne polyurethane glass transparent insulating coating is prepared from the acrylate dispersion serving as a componentA, the waterborne polyurethane curing agent serving as a component B, the nano ATO serving as an infrared reflecting material and the other aids. The double-component waterborne polyurethane glass transparent insulating coating has the advantages of extremely low VOC, high transparency, high hardness, strong adhesive force, high water resistance, high infrared reflectivity, high weather resistance, no toxin and environmental protection, and capacity of effectively overcoming the defect that the common emulsion coatings have low hardness, poor adhesive force, and poor water resistance, and canbe widely applied to civilian building glass and automobile glass.

Description

technical field [0001] The invention relates to a paint, in particular to a two-component water-based polyurethane glass transparent heat-insulating paint which is used for decoration and protection of glass surfaces, especially with heat-insulating and heat-preserving functions. Background technique [0002] Saving energy, reducing consumption, and improving economic benefits are one of the basic goals of scientific research and technology development, and coating technology is no exception. After the 1970s, the world's climate became warmer, and the earth's energy sources were increasingly exhausted. Therefore, it is of great practical significance to develop thermal insulation coatings, especially building thermal insulation coatings that are closely related to human life. In my country's energy consumption, building energy consumption accounts for about 1 / 4 of the national energy consumption, while energy consumed through glass doors and windows accounts for more than 5...
