The history and performance of insulation coatings.

Building insulation
coating
, with high efficiency, thin layer, thermal insulation, decoration, waterproof, fireproof, anti-corrosion, insulation in one of the new space energy-saving reflective thermal insulation coating, paint can be connected by closed microbeads on the surface of the object three-dimensional network ceramic fiber structure, paint insulation The grade reaches R-30.1, the heat reflectivity is 90%, the thermal conductivity is 0.04W/m.K, can effectively inhibit the solar and infrared radiation heat and conduction heat, insulation suppression efficiency can reach about 90%, can maintain 70% of the heat in the building space does not lose. Insulation insulation material is to improve the air phase clearance rate, reduce the thermal conductivity and conduction coefficient mainly. Fiber insulation materials in the use of the environment to spread heat and radiation heat transfer elevated, there must be a thicker cladding, and profile inorgy insulation materials to carry out assembly construction, there are many seams, damage to aesthetics, poor water resistance, short service life and other defects.
, people have been looking for and research a new material that can greatly improve the insulation reflectivity of insulation materials. In the 1990s, NASA researchers developed a new type of space insulation reflective porcelain layer (Therma-Cover) to solve the problem of heat transmission control in space vehicles, which is made up of tiny ceramic particles suspended in inert latex, which has high reflectivity, high radiation rate, low thermal conductivity, low heat storage coefficient and other thermal properties, and excellent thermal insulation. This high-tech material has been widely used in the field of aerospace in foreign countries for use in construction and industrial facilities, and has been exported to China for use in some large-scale industrial facilities. But what is lacking in the U.S. and China is that the high price of the material at $20/kg is really making many industries in China sigh and bear.
In this way, the domestic quietly set off a wave of research and development of thermal insulation of new materials, and Beijing Zhisheng Weihua Technology Development Co., Ltd. has taken the lead in the domestic counterparts to develop a successful high-efficiency, thin layer, insulation energy saving, decorative waterproofing in one of the new space reflective insulation coating. The coating selected silicone emulsion and water-based fluorocarbon emulsion with excellent heat, weather resistance, corrosion resistance and water-based fluorocarbon emulsion as
filmed substances
, using very fine hollow ceramic particles known as space age materials as fillers, from hollow The coating film, which is made up of multi-combination arrangement of ceramic particles, reflects the visible light in the range of 400 to 1800nm and the solar heat in the near-infrared region, and introduces the air micro-porous layer with very low thermal conductivity in the coating film to isolate the transmission of heat energy. In this way, by strengthening the significant impedance of reflecting solar heat and tropostic transmission, it can effectively reduce radiation heat transfer and heat transfer, thereby reducing the thermal balance temperature of the surface of the object, which can reduce the roof temperature by up to 20 degrees C and the indoor temperature by 5 to 10 degrees C. Product insefficient level of R-33.3, thermal reflectivity of 89%, thermal conductivity of 0.030W/m.K. Development trend: Building insulation is an important aspect of saving energy, improving living environment and using function. The proportion of building energy consumption in the total energy consumption of human beings is generally 30-40%, the vast majority of heating and air conditioning energy consumption, so building energy conservation is of great significance.
And because the insulation insulation coating to water as a dilution medium, does not contain volatile organic solvents, no harm to the human body and the environment, its production cost is only about 1/5 of similar products abroad, and it as a new type of thermal insulation coating, has good economic benefits, energy conservation and environmental protection, insulation effect and construction simplicity and other advantages and more and more people's attention and favor. And this kind of space insulation reflective coating is experiencing a change from industrial insulation insulation to building insulation-based direction, from thick layer to thin layer insulation insulation technology transformation, which is also one of the main development direction of insulation insulation materials in the future. Space reflective insulation coating through the application of ceramic sponge particle hollow material in the coating formed a vacuum cavity layer, to build an effective thermal barrier, not only its own large thermal resistance, low thermal conductivity, but also high thermal reflectivity, reduce the absorption of solar radiation heat in buildings, reduce the surface covered and internal space temperature, so it is unanimously recognized by the industry as one of the development prospects of energy-efficient materials. Today, the global insulation insulation materials are moving towards high efficiency, energy saving, thin layer, insulation, waterproof external protection integration direction, in the development of new insulation insulation materials and in line with structural insulation energy-saving technology at the same time, more emphasis on targeted use of insulation insulation materials, according to standard design and construction, and strive to improve insulation efficiency and reduce costs. In recent years, domestic and foreign research has been carried out thin layer insulation insulation coatings, the United States has a number of companies to produce this insulation porcelain coating, such as the United States SPMThermo-Shield, Thermal Products Systems launched Ceramic-Cover, J.H. International's Therma-Cover and other products, the best insulation insulation materials are insulation materials:

This space insulation porcelain layer is based on NASA control of the space shuttle thermal conduction work principle developed, suitable for high-pressure spraying, non-polluting, with good heat radiation, thin layer insulation, waterproof corrosion and other properties. At present, the material has been turned to general industrial and civil insulation insulation. And there are a number of domestic enterprises in the development of such materials, such as thin layer insulation reflective coatings, solar thermal reflection insulation coatings, water-based reflective insulation coatings, thermal insulation coatings, ceramic insulation coatings and so on. Mainly the use of good weather resistance, strong water resistance, strong anti-aging, strong bonding force and elasticity, and can be with insulation fillers, reflective fillers soluble membrane materials, choose light and hollow, high temperature resistance, thermal resistance, and Fillers with good reflectivity and radiation, high refractive coefficient, high surface finish, high thermal reflectivity and high radiation rate of ultra-fine powder suitable as reflective fillers, together with film-formed substates to form a low-radiation heat transfer layer, can effectively block the transfer of heat.
