Problems solved by technology

The disadvantage of radiation-type heat-insulating coatings is that the selection of base materials and the sintering process of materials are relatively complicated; although barrier-type heat-insulating coatings have the advantages of low thermal conductivity, small dielectric constant and corrosion resistance, they are not resistant to water and have low adhesion. and low temperature resistance; and reflective heat insulation coating is a relatively new technology, which has the advantages of good heat insulation effect, simple process, light weight and long durability, and is worthy of further research

Description

technical field [0001] The invention relates to the field of coatings, in particular to a composite heat-insulating coating and a preparation method thereof. Background technique [0002] With the rapid growth of my country's economy and society and the rapid progress of science and technology, people's requirements for the environment and materials are also getting higher and higher. Among them, people's requirements for their own living environment have also been greatly improved, and the excessively high surface temperature of the house due to heat absorption of materials is one of the problems that people are eager to solve. Therefore, it is of great significance to research and develop a heat-insulating coating with good effect to solve this problem. Thermal insulation coating is a new type of functional coating that has been very popular in research in recent years. Applying it to the wall surface can reduce the internal temperature of the building, thereby achieving ...
