Problems solved by technology

[0002] If the window film pasted on the glass surface of the existing car does not have the anti-fog function, especially after fogging in bad weather, the driver's vision will be blurred, which will bring great hidden dangers to safety.
At present, the anti-fog methods mainly include electric heating and the use of anti-fog coatings. The former has good effect but is expensive and wastes resources. The latter is just spraying anti-fog coatings on glass and other surfaces, but it cannot be cured, so the anti-fog durability is poor and Inconvenient to use
In addition, the performance of the existing window film is single, and it is difficult to meet the requirements of anti-fog, heat insulation and aesthetics

Abstract

The invention relates to an antifoggant composition and an antifog and heat-insulation colored window film formed by the composition. The antifoggant composition consists of the following components in percentage by weight: 9%-14% of hydrophilic resin, 55%-76% of propylene glycol monomethyl ether, 3%-10% of dimethyl amine, 1%-5% of triethylenediamine, 1%-5% of flatting agent, 5%-26% of isopropyl alcohol and 5%-24% of ethanol. The antifog and heat-insulation colored window film is formed by compounding an antifoggant coating (1), a first transparent polyester film or transparent polyester film substrate (2-1), a colored heat-insulation crylic acid adhesive layer (3-1), a second transparent polyester film or transparent polyester film substrate (2-2), a crylic acid adhesive layer (3-2) and a release film (4) into a whole, wherein the antifoggant coating (1) is formed by the antifoggant composition, and the colored heat-insulation crylic acid adhesive layer (3-1) contains specific heat insulation substances. The window film is antifogging, beautiful and heat-insulating.

Description

technical field [0001] The invention relates to an anti-fogging agent composition and an anti-fogging and heat-insulating colored window film formed by the composition, which is particularly suitable for sticking on the glass surface of an automobile. Background technique [0002] If the window film pasted on the glass surface of the existing automobile does not have the anti-fog function, especially after the fog is formed in the case of bad weather, the vision of the driver will be blurred, which will bring great hidden danger to safety. The current anti-fog methods mainly include electric heating method and the use of anti-fog coatings. The former has good effect but high price and waste of resources. The latter only sprays anti-fog coatings on surfaces such as glass, but cannot be cured. Inconvenient to use. In addition, the performance of the existing window film is single, and it is difficult to take into account the requirements of anti-fog, heat insulation and aesth...
