Problems solved by technology

[0004] In the cold winter or rainy season, the water vapor in the cab or the hot air in the car will condense into dewdrops on the cold glass surface, which will greatly reduce the light transmittance of the glass, affect the line of sight, bring great inconvenience to life, and even cause Dangerous; especially in the rainy season, if the windows are not wiped, the driver cannot drive normally at all, and must stop the car to wipe off the fog with a rag before continuing to drive
The atomization phenomenon also causes a lot of waste of resources, such as rust and corrosion of steel, etc.

Abstract

The invention discloses a heat-insulation anti-fogging film for automobile glass. The heat-insulation anti-fogging film is composed of an anti-fogging wear-resisting layer, a first transparent polyester film layer, a heat insulation layer, a second transparent polyester film layer, a pressure-sensitive rubber layer and a releasing layer in sequence; the anti-fogging wear-resisting layer comprises, by weight, 20-30 parts of acrylic resin, 2-3 parts of boron nitride nanosheets, 3-6 parts of sorbitan carboxylic acid ester, 2.5-5 parts of silicon-containing surfactant, 1-3 parts of a curing agent and 40-60 parts of organic solvent; the heat insulation layer comprises, by weight, 15-32 parts of acrylic resin, 0.5-1.5 parts of silicon nitride, 1-2 parts of hollow silica nanoparticles, 5-8 parts of diphenyl ketone type ultraviolet absorbent, 6-12 parts of Carbomer, 0.3-1 part of a cross-linking agent, 10-20 parts of acetic ether and 15-30 parts of dimethylformamide. The heat-insulation anti-fogging film is good in wear resistance and heat-insulation anti-fogging effect, and economical and environment friendly.

Description

[0001] Technical field: [0002] The invention relates to the technical field of material chemistry, in particular to a thermal insulation and anti-fog film for automobile glass. [0003] Background technique: [0004] In the cold winter or rainy season, the water vapor in the cab or the hot air in the car will condense into dewdrops on the cold glass surface, which will greatly reduce the light transmittance of the glass, affect the line of sight, bring great inconvenience to life, and even cause Dangerous; especially in the rainy season, if the window is not wiped, the driver cannot drive normally at all, and must stop the car to wipe the fog with a rag before continuing to drive. The atomization phenomenon also causes a lot of waste of resources, such as rust and corrosion of steel. [0005] At present, the research on anti-fogging agents for glass is in the stage of active development, especially with the development of the automobile industry, all countries have launched ...
