Problems solved by technology

According to statistics, the proportion of building energy consumption in the entire energy consumption is generally 30-40%, and most of them are energy consumption in heating and cooling. As an important part of building energy conservation, thermal insulation coatings have become an important part of the industry. It is a hot topic of research and has been paid attention to by countries all over the world. However, the thermal insulation effect of existing coatings is still poor and cannot meet people's needs.

Abstract

The invention relates to thermal insulation paint and a preparation method thereof and a thermal insulation coating. The thermal insulation paint is prepared from, by mass, 15-30 parts of main ingredient, 3-22 parts of acrylic polymer hollow spheres, 15-40 parts of water and 0.5-1.5 parts of thickener, wherein the main ingredient is polymer resin of which the elastic elongation ratio is 800% or above, and the glass transition temperature is below -10 DEG C. The thermal insulation paint is good in thermal insulation effect.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a thermal insulation coating, a preparation method thereof and the thermal insulation coating. Background technique [0002] Making buildings thermally insulated can not only save energy, but also improve the quality of living. According to statistics, the proportion of building energy consumption in the entire energy consumption is generally 30-40%, and most of them are energy consumption in heating and cooling. As an important part of building energy conservation, thermal insulation coatings have become an important part of the industry. The popular topic of research is paid attention to by countries all over the world. However, the thermal insulation effect of existing coatings is still relatively poor and cannot meet people's needs. Contents of the invention [0003] In view of this, it is necessary to provide a thermal insulation coating with better thermal insulat...
