Description

technical field [0001] The invention relates to the technical field of thermal insulation coatings, in particular to an inorganic thermal insulation coating and a preparation process thereof. Background technique [0002] With the improvement of people's awareness of environmental protection, how to solve the heat preservation inside and outside of buildings and reduce energy consumption is an urgent problem to be solved. However, the existing materials generally adopt thick paste type, which not only has high construction cost, but also has low material utilization rate and unsatisfactory thermal insulation effect. The use of thermal insulation coatings on the building surface can effectively reduce the temperature of the building surface and interior, and alleviate the temperature change of the building surface. It not only has a good protective effect on the building, but also greatly reduces the use of air conditioners in the building. Saving energy is of great signific...
