Problems solved by technology

However, the above-mentioned ceramic balls can only reduce the thermal conductivity of the thermal insulation coating to a limited extent, and its thermal conductivity is generally between 0.1-0.3W/m.k, and the reflectivity of the thermal insulation coating is between 80-90%.
In general, reducing the thermal conductivity will result in a decrease in reflectivity
At the same time, the formed coating has weak UV resistance, is not wear-resistant, is not flame-retardant, and has a relatively short service life.
In addition, the thermal insulation coatings on the market generally have poor waterproof performance and adhesion, easy to crack and fall off, poor storage stability, high price, inconv

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermal insulation coating and a preparation method thereof. Background technique [0002] In recent years, with the intensification of the global heating effect, energy conservation and emission reduction have become a common problem faced by the world's construction industry. my country's resources are relatively insufficient, but energy consumption is increasing day by day. Energy issues have become the main factor restricting economic development, and energy conservation is urgent. In my country, building energy consumption accounts for a large proportion of the total energy consumption. Therefore, it is very necessary to develop building insulation materials that are conducive to energy saving. [0003] As a common building insulation material, building thermal insulation coatings are more and more popular because of their advantages such as convenient use, good thermal ...
