Abstract

The invention provides a preparation technology of a high-weather-resistance anti-fogging heat insulation membrane. The technology comprises the steps that silicon nitride whiskers are mixed with a sodium lauryl benzene sulfonate solution and then mixed with ethanol; ethyl silicate and the ethanol are mixed, and the ethanol is cooled down to a room temperature after stirring reaction is conducted;silica alcosol is sequentially added to methacryloxypropyl trimethoxy silane and methacrylic acid, stirring reaction is conducted, and modified silica alcosol is mixed with a suspension; hydrophilicthermal curing solvent acrylic resin, propylene glycol monomethyl ether, dimethylformamide, a catalyst triethylenediamine, a flatting agent, isopropyl alcohol and the ethanol are stirred and mixed; the surface of a glass plate is sequentially coated with coating liquid and tape casting liquid. The anti-fogging heat insulation membrane has the advantages of excellent wear resistance, weather resistance and stability, ageing is not easily caused, so that the service life of the anti-fogging heat insulation membrane is effectively prolonged, better heat insulation and air permeable performance are achieved, an anti-fogging effect is enhanced, and the anti-fogging time is prolonged.

Description

technical field [0001] The invention relates to the technical field of anti-fog films, in particular to a preparation process of a highly weather-resistant anti-fog and heat-insulation film. Background technique [0002] With the popularity of private cars, the automotive aftermarket has gradually become a gold industry, and the automotive anti-fog and heat insulation film market occupies a pivotal position in the automotive aftermarket. The anti-fog heat insulation film prepared by the existing technology has insufficient wear resistance and weather resistance, which leads to the aging of the anti-fog heat insulation film after a period of use, and the loss of anti-fog heat insulation effect, and there are also low light transmittance and heat insulation. The defects of poor effect, low ultraviolet reflectance, inconspicuous anti-fog effect and short anti-fog time. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provi...
