Description
Technical field
The application belongs to speciality coating field, particularly, the application relate to a kind of transparent heat-insulated/antiultraviolet glass paint.
Background technology
Under the background of energy dilemma, energy-conserving and environment-protective become the focus that people pay close attention to.Along with rapid development of economy, China has become second-biggest-in-the-world energy expenditure state, and in 3 to five years, likely surmounts the U.S. become energy expenditure state the biggest in the world.Therefore, the sustainable development of energy-conserving and environment-protective to China's economy is vital.Modern architecture adopts glass wall curtain more and more in order to attractive in appearance, although glass is attractive in appearance, transmittance is high, the visual field is good, it is inadequate to the ultrared obstruct from sunlight, adds the rate of utilization of air-conditioning, causes huge energy dissipation.In this context, nano transparent insulating coating has become the new lover of energy-saving and environment-friendly paint, it uses field widely, as house, office building, hotel, school, automobile etc. had both required that heat-insulation and heat-preservation intercepted ultraviolet, have the place of special requirement especially applicable to light transmission and to sight line again, energy-saving potential is huge.
Ultraviolet energy can cause skin aging, even easily cause skin carcinoma, also can cause various curtain and floor, the fading of plastics and printed matter.Being radiated at ground wavelength region is that the ultraviolet of 290-400nm accounts for 6% of total solar energy, and wherein, belong to 290-320nm short wavelength UV-B scope and account for 0.5%, the wavelength region belonging to 320-400nmUV-A accounts for 5.5%.Therefore, UV-A accounts for the overwhelming majority.Because in ultraviolet, the wavelength of UV-A is longer, so UV-A more easily passes cloud layer and glass, to skin and object damage larger, although UV-A is less than the degree of depth of UV-B transdermal, but UV-B is in skin surface scattering and be absorbed by the skin and easily make skin tanning, and UV-A can be penetrated into hypodermis layer, produces free radical in skin histology, the free radical generated makes skin aging produce wrinkle, and the elasticity of skin is reduced.Can cell membrane and gene some be caused to affect in addition.Therefore people more and more pay close attention to the harm of resisting ultraviolet radiation, particularly windshield glass of automobile and the life of the windowpane such as room, office to people directly works the mischief.
Ultraviolet screener principle is divided into two classes substantially.One class is mineral compound, as TiO
2, ZnO, ATO, ITO etc., but the transparency and ultraviolet absorption, reflection potential all very limited, DeGrain.Another kind of is organic compound, and most typical is benzotriazole cpd, and they have UV receptivity, but due to the persistence of effect and the problem of secure context, uses field also very limited.
At present in our ultraviolet screener that can see or coating, seldom have the transparency and all good situation of UV resistance effect, and antiultraviolet of the prior art is difficult to directly be used on the building glass such as windshield and telecommuting room.
