Building energy conservation has become one of the important goals of energy conservation in China. Data show that China’s use of the process of building energy consumption accounted for 27.6% of total social energy consumption, and the economy more developed, the higher the standard of living, the greater the proportion will be. The rapid development of urbanization will lead to the rapid growth of urban population, combined with the development of the industry, the increase in automobile ownership and the increasing number of buildings, will make the city’s “heat island effect” become more and more obvious, which will make Building insulation, insulation requirements more urgent. Effectively reducing the surface temperature of buildings and various facilities, for the protection of the environment, energy conservation and improve the living environment and so have a very important significance. Therefore, with the increasing use of architectural coatings, building energy conservation has become a major problem affecting the overall socio-economic development.
In the past, the building insulation technology is mainly used to achieve low thermal conductivity of the material, commonly used polystyrene board material thickness of 30 ~ 50mm, the insulation structure is complex, the construction is very difficult. In contrast, the thermal insulation coating is through the building inside and outside the wall and the top coated with a layer of barrier, reflection, radiation and other effects of the coating to achieve energy saving and insulation purposes of the thin functional coatings. Now, thermal insulation coating has become a new material development and production of new hot spots.
