Embodiment 1

[0025] This embodiment provides a nano-glass heat-insulating coating, which can be painted on glass to form a film, and has the function of blocking heat and ultraviolet rays. The heat-insulating coating includes: polyol A component and curing agent B component;

[0026] Among them, the polyol A component is mixed with nano-antimony tin oxide slurry and water-based polyurethane in a mass ratio of 4:1 to 1:1, dispersed at a speed of 800r / min for 30 minutes, and then added to the polyol A component Divide 1.7-15% of the total mass of curing agent B component additives, and disperse at a speed of 400r / min-450r / min for 60 minutes to obtain polyol A component; wherein, the additives include: adhesion promotion agents, wetting agents, leveling agents, defoamers and thickeners;

[0027] The nano antimony tin oxide slurry used in the polyol A component is based on nano antimony tin oxide, a mixture of water and absolute ethanol formed by mixing 1:1 by volume, and a polymer anion dispe...

Embodiment 2

[0041] This embodiment provides a nano-glass heat-insulating coating, which can be painted on glass to form a film, and has the function of blocking heat and ultraviolet rays. The heat-insulating coating includes: polyol A component and curing agent B component;

[0042] Each component and consumption are basically the same as those given in Example 1. The difference is that the ratio of the water-based polyurethane used in the polyol A component and the nano-ATO slurry is 4: 2 by mass ratio, and water can be added to the water-based polyurethane simultaneously. For dilution, the raw materials are taken according to the mass ratio of water-based polyurethane, nano-ATO slurry, and water in a ratio of 4:2:2. The preparation method of the polyol A component is the same as in the above-mentioned embodiment 1, and will not be repeated here.

[0043] Prepare the nano-glass heat-insulating coating, and after the obtained coating is coated with the same method, the relevant properties ...

Abstract

The invention discloses a nano-glass heat insulation paint and a preparation method thereof, belonging to the field of paint. The paint comprises component A and component B, wherein the polyalcohol component A is formed by mixing waterborne polyurethane and nano antimony tin oxide slurry according to the mass ratio of 4: 1-1: 1; curing agent is isocyanate curing agent; the mass ratio between thecomponent A and the component B is 10: 1; in the polyalcohol component A, the nano antimony tin oxide slurry is prepared by taking mixture of nano antimony tin oxide, water and absolute ethyl alcohol(mixing according to the volume ratio of 1: 1), and polymer anion dispersing agent as raw materials, and has the solid content of 20%; and the nano-glass heat insulation paint is prepared by taking the waterborne polyurethane, the nano antimony tin oxide slurry, the water, adhesive force accelerating agent, wetting agent, flatting agent, thickening agent, defoaming agent and the isocyanate curingagent as raw materials. The invention has the advantages of simple paint preparation, low cost, good heat insulation property, being environment-friendly and safe, and the like.

Description

technical field [0001] The invention relates to a coating, in particular to a nano-glass heat-insulating coating for building energy saving and a preparation method thereof. Background technique [0002] Nano glass thermal insulation coating is a functional architectural coating used on glass. It is directly painted on the glass surface to form a thin film, which has the function of blocking infrared and ultraviolet rays, and has a high transmittance of visible light. This kind of coating was first invented in Japan, and it has been widely popularized and promoted in Japan at present. Its representative brand is Horuijia Transparent Glass Thermal Insulation Coating. In China, glass thermal insulation coatings have also developed rapidly in recent years. At present, some domestic manufacturers have produced thermal insulation coatings for glass. [0003] There are two types of glass heat-insulation coatings: water-based and oil-based. The oil-based glass heat-insulation coat...
