Embodiment example 1

[0012] The thickness of the dry film of the coating is 20 μm. The heat insulation effect of the coating varies with the content of ATO in the dry film. Through the change of the air temperature in the box and the temperature on the back of the glass plate with different ATO content in the dry film, you can see Results: The thermal insulation effect of the coated glass without adding ATO is basically the same as that of the blank glass, and the heating curves almost coincide. When the ATO content in the dry film is 0.97%, the heat insulation effect has already begun. With the increase of ATO content, the heat insulation effect of the coating film is enhanced. It can be seen from the corresponding temperature change that the temperature change is gradually gentle, and the final value after 30 min gradually decreases. When the ATO content in the dry film is 9.62% and 10.53%, the thermal insulation temperature difference between the coated glass and the blank glass is 7.4°C and 7....

Embodiment example 2

[0014] When the ATO content in the dry film is 9.62%, it is a more appropriate dosage. By changing the thickness of the dry film to test, it can be seen from the change of temperature with time that the thickness of the coating film gradually increases, and its heat insulation effect gradually increases. The change of temperature tended to be gentle, and the temperature value gradually decreased after 30 min. When the dry film thickness reaches 50 μm, the thermal insulation temperature difference is 9.3°C, but its light transmittance is poor. Considering comprehensively, when the dry film thickness is 18 μm, the heat insulation effect is obvious and the light transmittance is better, which is the most suitable coating thickness.

Embodiment example 3

[0016] Under the condition that the content of nano-ATO in the coating is the same (the content in the dry film is 9.62%), an appropriate amount of color paste is added according to the pigment content of different color pastes (to ensure that the PVC of each coating is the same), and the thickness is 20 μm on the glass plate. The coating film is compared with the nano-ATO coating film without color paste, and the heat insulation effect of the colored transparent heat insulation coating of different colors is tested. It can be seen from the test results that the four color pastes of red, blue, green and yellow have no obvious influence on the heat insulation effect of the coating film, and their temperature changes are almost coincident with those of the ATO coating film without color paste. The carbon black paste made the thermal insulation effect of the coating film better, and the temperature after 30 min was the lowest, but it also made the light transmittance of the coatin...

Abstract

The invention discloses transparent heat-insulating paint. The transparent heat-insulating paint taking nano antimony tin oxide (ATO) as functional powder is prepared by taking waterborne hydroxyl acrylic acid and amino resin as film forming substances and nano ATO as heat-insulating functional powder. Hardness of a film formed by coating the paint on glass and baking at 170-180 DEG C, adhesive force is 0 grade, resistance to water, acid and alcohol is excellent, transmittance in a visible light area (380-780nm) is higher than 60%, near infrared rejection rate is higher than 50%, and content of nano ATO, coating dry film thickness and impact of coating orientation on heat-insulating effect are investigated. A colored transparent coating having good heat-insulating effect is prepared by adding waterborne color paste on the basis to meet special decoration needs.

Description

Technical field [0001] The invention relates to a heat-insulating paint, in particular to a transparent heat-insulating paint. Background technique [0002] In residential buildings, the heat sources that can affect the indoor temperature come from both indoors and outdoors. Among the heat sources from the outside, one is the heat energy directly irradiated into the room by the sun, which is mainly concentrated in the 0.3-2.5μm band; the other is the heat energy that the sun irradiates on objects (roads, buildings, etc.) and is absorbed by the objects and then radiated out again. Thermal infrared radiation is mainly concentrated in the 2.5-40μm band. Among the indoor heat sources, one is thermal infrared radiation radiated again after absorbing solar radiation by walls, floor furniture, etc.; the other is thermal infrared radiation generated by heating, stoves and electrical appliances, both of which are concentrated in the 2.5-40μm band superior. In the cold winter, peop...
