Problems solved by technology

[0008] According to the collected literature, the inorganic active ingredients in glass thermal insulation coatings mainly involve tin oxide, tin antimony oxide, indium tin oxide, zinc oxide, ferric oxide, silicon oxide or titanium oxide; The disadvantage of the film process is that the film forming period is long, which is not conducive to the wide use of heat insulation coatings

Abstract

The invention relates to a heat-insulating coating with spectral selectivity, which is characterized in that functional coatings can be formed on surfaces of transparent substances such as glass so that part of the heat of sunlight is insulated with the proviso that the transmittance of visible light is guaranteed; energy consumption of the air conditioner or other devices is saved; and the coating is widely applicable to automobile window, building window, etc. The characteristic lies in that cobalt-based micro-nano materials are introduced into the inorganic heat-insulating component of the coating, and also lies in that ultraviolet curing technology with good environmental compatibility is employed to perform the film forming of the heat-insulating coating on the substrate, which is benefit for the large-scale continuous production of heat-insulating glasses.

Description

Technical field: [0001] The invention belongs to the field of nano coatings, and relates to a spectrally selective nano heat-insulating coating, which is applied to transparent substrates such as glass, and realizes blocking of solar heat while ensuring the transmission of visible light. Background technique: [0002] With the gradual warming of the global climate and the increasing shortage of energy in the world, people pay more attention to reducing unnecessary energy consumption through technological progress while developing and utilizing new energy and renewable energy. The energy used by cooling and refrigeration equipment in the construction industry, petroleum industry, transportation industry, and weapon industry accounts for more than 20% of the total annual energy consumption. Therefore, it is an important research topic to reduce or prevent the temperature rise caused by strong solar radiation, thereby saving energy and improving the living and working environme...
