Building insulation is an important aspect of saving energy, improving the living environment and using functions. Building energy consumption accounts for 30-40% of the total energy consumption of human beings. Most of them are energy consumption for heating and air conditioning, so building energy conservation is of great significance. Moreover, since the thermal insulation coating uses water as a dilution medium and does not contain volatile organic solvents, it is harmless to the human body and the environment; its production cost is only about one-fifth that of similar foreign products, and it is used as a new type of thermal insulation. Coatings, with good economic benefits, energy saving and environmental protection, heat insulation effect and simple construction, have attracted more and more people's attention and favor. And this space adiabatic reflective coating is undergoing a transition from industrial thermal insulation to building thermal insulation, from thick layer to thin layer thermal insulation technology, which is also the main insulation material in the future. One of the development directions. The space reflection insulation coating constructs an effective thermal barrier by applying a vacuum cavity layer formed by the ceramic spherical particle hollow material in the coating, which not only has large thermal resistance, low thermal conductivity, but also high heat reflectivity, reducing the building to the sun. The absorption of radiant heat reduces the temperature of the coated surface and the internal space, so it is recognized by experts as one of the most promising energy-efficient materials.
Today, global thermal insulation materials are developing in the direction of high efficiency, energy saving, thin layer, heat insulation and waterproof external protection. In the development of new thermal insulation materials and in line with structural insulation and energy saving technology, more emphasis is placed on the use of targeted insulation. Insulation materials, designed and constructed according to standard specifications, strive to improve insulation efficiency and reduce costs. At home and abroad, research on thin-layer thermal insulation coatings has been carried out. Many companies in the United States have produced such thermal insulation coatings, such as SPM Thermo-Shield in the US, Ceramic-Cover from Thermal Protective Systems, and Therma-Cover from JH International. And other products. This space-insulated porcelain layer is developed according to the working principle of NASA's control of space shuttle heat conduction. It is suitable for high-pressure spraying, pollution-free, with good heat radiation resistance, thin layer heat insulation and waterproof protection. Corrosion and other properties. The material has been turned to general industrial and civil insulation. There are also many companies in China that are developing such materials, such as thin-layer heat-reflective coatings, solar thermal reflective coatings, water-based reflective thermal insulation coatings, thermal sunscreen coatings, ceramic thermal insulation coatings, and so on. It is mainly used as a film-forming material with good weather resistance, strong water resistance, strong aging resistance, strong adhesion and elasticity, and good compatibility with thermal insulation filler and reflective filler. It is light and hollow and resistant to high temperature. A filler with high thermal resistance, good reflectivity and radiation, ultra-fine powder with high refractive index, high surface finish, high heat reflectivity and high emissivity is suitable as a reflective filler, and together with the film-forming binder constitutes low radiation transmission. The hot layer can effectively block the transfer of heat. The thin-layer heat-insulating reflective coating is used in combination with porous materials for painting in buildings, vehicles, petrochemical tank equipment, grain storage, cold storage, containers, pipelines, etc.
