[China paint information] building energy conservation is one of the important links related to the construction of low-carbon economy, the completion of energy conservation and emission reduction goals, and the maintenance of sustainable economic development in China. Recently, At the second and third general meeting of Shenzhen Coating Technology Association and the Ninth National Innovative Green Coating Technology Summit Forum in 2018, Liu Bo, a doctor and professor of the school of chemistry and chemical engineering of Shenzhen University, made an academic report on efficient and energy-saving reflective building exterior wall thermal insulation coating, pointing out that in the emerging stage, it is necessary to make full use of the reflective thermal insulation coating technology at the end of the test or when the user forcibly interrupts it, Achieve building efficiency and energy conservation. Ceramics: the use of reflective thermal insulation coating can reduce the heat flow from the source and reduce building energy consumption; It can reduce the maximum temperature of the wall surface in the daytime, reduce the stress caused by the rise of temperature, and improve the durability of the coating after coating. And the reflective thermal insulation coating has the characteristics of achieving better thermal insulation effect under a small thickness, which is not available in general barrier coatings

Professor Liu Bo said that compared with traditional coatings, reflective thermal insulation coatings have higher light reflectance; At the same time, it also has good infrared radiation performance, which is conducive to heat exchange between the coating and outer space, and eliminates the coating temperature rise caused by a small amount of solar radiation

Professor Liu Bo pointed out that at present, building energy consumption accounts for about 25% of the total energy consumption in China, and it is the industry with the largest energy consumption. And only 3% of the new buildings are energy-saving buildings, up to 97% are high-energy buildings. By 2020, China's building energy consumption will reach a staggering 1.1 billion tons of standard coal. The huge building energy consumption will not only cause a waste of resources, but also bring serious environmental pollution. Therefore, energy conservation, especially building energy conservation, is particularly important

Professor Liu Bo suggested in the report that building energy conservation is a systematic project, which can improve the energy-saving effect of buildings through local improvement of buildings. The recyclable and renewable multi-layer composite flexible packaging film of building envelope composed of windows, walls and floors - such as pet/polypropylene, pet/polyethylene, and metal plastic composite heat insulation is an important aspect of saving resources and improving the living and use functions of buildings. With the increasingly serious energy crisis and the vigorous development of new materials, the state pays more and more attention to energy-saving buildings. Reflective thermal insulation coating plays a great role in the wall insulation of new energy-saving buildings
