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 in bad weather, it is easy to form fog, making the vision blurred when traveling, which brings 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

Abstract

The invention relates to an anti-fogging agent composition and an anti-fogging insulation window film formed thereby, wherein the anti-fogging agent composition comprises 9 to 14 wt% of hydrophilic resin, 55 to 76 wt% of propylene glycol monomethyl ether, 3 to 10 wt% of dimethyl methylamine, 1 to 5 wt% of triethylene diamine, 1 to 5 wt% of leveling agent, 5 to 26wt% of isopropanol and 5 to 24wt% of ethanol; the anti-fogging insulation window film comprises a first transparent polyester film or transparent polyethylene film substrate (2-1), a heat insulation acrylic adhesive layer (3-1), a second transparent polyester film or transparent polyethylene film substrate (2-2), an acrylic adhesive layer (3-2) and a release film (4), which are composited as a whole, wherein the anti-fogging coating (1) is formed by the anti-fogging agent composition; and the heat insulation acrylic adhesive layer (3-1) contains a specific insulation material. According to the invention, the anti-fogging insulation window film is anti-fogging, insulating and safe.

Description

technical field [0001] The invention relates to an anti-fogging agent composition and an anti-fogging and heat-insulating window film formed by the composition, which is especially suitable for pasting 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 in bad weather, it is easy to form fog, making the vision blurred when traveling, which brings 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. Therefore, there is an urgent need to develop an antifogging agent and apply the antifogging agent to the window film, so that the window film n...
