A kind of transparent glass thermal insulation coating

Abstract

The invention discloses a transparent glass thermal insulating coating which comprises the following components in parts by weight: 30-50 parts of crylic acid modified organic silicon resin, 15-20 parts of low viscosity high chlorinated polyethylene resin, 5-10 parts of nanometer titania, 2-3 parts of nano-zinc oxide, 20-30 parts of n-butyl acetate, 2-5 parts of n-butyl alcohol and 2-5 parts of cyclohexanone. The coating disclosed by the invention is relatively high in shielding rate in an infrared area, good in transmissivity in a visible light area, and remarkable in absorption effect in an ultraviolet area, the transmissivity of visible light is greater than 80%, the shielding rate of infrared light is greater than or equal to 61%, the energy-saving effect is remarkable, the temperature can be reduced by 5-10 DEG C, and the energy can be saved by 20-30%. The coating is good in adhesion to surfaces of glass products, has a self-cleaning function, is free of charge, water or dust on the surface, and can be applied to coating on surfaces such as door and window glass, automobile glass and glass curtain walls of high-rise buildings.

Description

technical field [0001] The invention relates to a paint, in particular to a heat-insulating paint for transparent glass. Background technique [0002] At present, the thermal effect of the global environment is intensifying, and energy conservation and emission reduction are common problems faced by the world's construction industry. Building energy saving is to reduce the energy consumption of buildings for heating and cooling under the condition of ensuring comfortable room temperature. Glass is widely used in buildings as a transparent material. Studies have shown that the heat transfer coefficient of ordinary glass is 3.2 times that of walls and 5 times that of roofs. In addition, due to the transparency of ordinary glass, light can pass directly from one side of the glass to the other, causing the space inside the glass to be heated by sunlight. It can be seen that improving the heat insulation effect of glass windows is an important link in building energy saving and...

Problems solved by technology

[0003] In the prior art, products such as sticking film, heat insulating paper, and metal-coated heat insulating glass are usually used to realize the heat insulation problem of glass windows, but these products usually have problems such as low light transmittance, poor heat insulation effect, and complicated process.
