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 a thermal insulation coating. Background technique [0002] Enabling buildings to have the function of heat insulation can not only save energy, but also improve the quality of living. According to statistics, building energy consumption generally accounts for 30-40% of total energy consumption, and most of it is energy consumption for heating and cooling. Thermal insulation coatings, as an important part of building energy saving, have become the industry The hot topic of research has attracted the attention of countries all over the world. However, the thermal insulation effect of the existing coatings is still poor and cannot meet people's needs. Summary of the invention [0003] In view of this, it is necessary to provide a thermal insulation coating with better thermal insulation effect. [0004] In addition, a ...
