Building insulation is to save energy, improve the living environment and an important aspect of the use of functions. Building energy consumption proportion in the whole of human energy consumption is generally 30-40%, the vast majority of energy consumption for heating and air conditioning, so the building energy efficiency is of great significance. And because the insulation coating with water as the diluent medium, free of volatile organic solvents, no harm to humans and the environment; it is only about 1/5 the cost of production of similar foreign products, and it is as a new thermal insulation paint, has a good economic, energy and environmental protection, thermal insulation, and the advantages of simple construction and more and more people's attention and favor. Such reflective coating and the heat-insulating space is experiencing a direction from the thermal insulation to the building insulation industry based changes, by a thin insulation to thick-film technology shift, which is the next major insulation materials one of the development.
Space reflective insulating coating layer applied by a vacuum chamber of the hollow ceramic spherical particles in the coating material, to build an effective thermal barrier, not only its own thermal resistance, low thermal conductivity, high reflectivity and heat, reducing building sun absorption of radiant heat, reducing temperature of the coating surface and an interior space, it is recognized as one of experts unanimously promising energy-efficient material.
Today, the world is moving towards efficient insulation materials, energy saving, thin-layer, heat insulation, waterproof outer sheath direction of integration development, in the development of new insulation materials and energy-saving technologies in line with the structure of the insulation at the same time, more emphasis on the use of targeted heat insulation materials, according to standard design and construction standards, and strive to improve thermal efficiency and reduce costs. Have launched a thin layer of thermal insulation coatings research at home and abroad, the United States there are many companies producing such heat-insulating ceramic coating layer, such as the US SPM Thermo-Shield, Thermal Protective Systems launched Ceramic-Cover, JHInternational of Therma-Cover and other products. This space porcelain insulation layer is developed from the working principle of the United States Aeronautics and Space Space Administration NASA space shuttle control heat transfer for high-pressure spraying, pollution-free, it has a good thermal radiation, a thin layer of insulation, waterproof corrosion properties. This material has shifted to general industrial and residential insulation.
The home also has a number of enterprises in the development of such materials, such as thin-layer reflective coating insulation, solar heat-reflective insulation coatings, waterborne reflective insulation coatings, insulation sun paint, ceramic insulation coatings, and so on. Mainly used weatherability, water resistance, aging resistance, strong adhesion and elasticity, and capable of holding the filler, the filler good compatibility reflective film-forming material selected hollow lightweight, high temperature, high thermal resistance, and has good reflectivity and radiative fillers, high refraction coefficient, surface finish, higher thermal radiation reflectivity and ultra-fine powder is suitable as a reflective filler, and a film forming binder together constitute a low-E pass thermal layer, heat can be transferred effectively cut off. Such a layer of porous insulation material and reflective coating can be used in different places using a composite coating building, vehicle, tank petrochemical equipment, grain storage, cold storage, containers, pipes and the like.
