Problems solved by technology

[0003] Traditionally, the coatings are made of organic solvents, which are highly polluting. Therefore, water-based coatings have been used on a large scale. For exterior wall coatings, one of the important technical problems that needs to be solved is heat insulation, but now Some water-based coatings have poor heat insulation performance

Abstract

The invention discloses a water-based thermal insulation primer. The water-based thermal insulation primer is prepared from 30%-40% of organosilicone-acrylic emulsion, 22%-28% of ceramic microbeads, 20%-25% of deionized water, 8%-12% of filler, 5%-7% of additive, 0.2%-0.5% of antifoaming agent, 0.1%-0.5% of preservative and 0.5%-0.9% of thickening agent, wherein the inner diameter of the ceramic microbeads is smaller than 3 mu m and the volume weight is less than 180kg / m<3>. The water-based thermal insulation primer has good thermal insulation performance.

Description

technical field [0001] The present invention relates to a water-based thermal insulation primer. Background technique [0002] In various fields, coatings are widely used, such as exterior walls, industrial warehouses, chemical, petroleum, food industry storage tanks and pipeline surfaces, factories, modern farms, freezers, private houses, office buildings and other buildings, etc. . [0003] Traditionally, the coatings are made of organic solvents, which are highly polluting. Therefore, water-based coatings have been used on a large scale. For exterior wall coatings, one of the important technical problems that needs to be solved is heat insulation, but now Some water-based coatings have poor thermal insulation performance. Contents of the invention [0004] The purpose of the present invention is to provide a water-based thermal insulation primer with good thermal insulation performance. [0005] In order to achieve the above purpose, the water-based thermal insulatio...
