Problems solved by technology

[0002] The fogging on the glass surface of various glass doors and windows brings great inconvenience to production and life, and if the window film pasted on the glass surface of the car does not have the anti-fog function, especially after fogging in bad weather, it will make the driver The vision is blurred, which brings great hidden danger 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.
In addition, the existing window film is difficult to meet the requirements of anti-fog and aesthetics

Abstract

The invention relates to an antifogging agent composition and an antifogging colored window film formed by the same. The antifogging agent composition comprises 9-14wt% of hydrophilic resin, 55-76wt% of propylene glycol methyl ether, 3-10wt% of dimethyl methylamine, 1-5wt% of triethylene-diamine, 1-5wt% of leveling agent, 5-26wt% of isopropanol and 5-24wt% of ethanol. The antifogging colored window film comprises an antifogging agent coating layer (1), a first transparent polyester film or transparent polyethylene film substrate (2-1), a dyed acrylic acid adhesive layer (3-1), a second transparent polyester film or transparent polyethylene film substrate (2-2), an acrylic acid adhesive layer (3-2) and a releasing film (4) which are integrally composited, wherein the antifogging agent coating layer (1) is formed by the antifogging agent composition. The antifogging colored window film is antifogging, attractive, transparent and safe.

Description

technical field [0001] The invention relates to an antifogging agent composition and an antifogging colored window film formed by the composition, which is especially suitable for pasting on the glass surface of a building, the glass surface of a bathroom or the glass surface of an automobile. Background technique [0002] The fogging on the glass surface of various glass doors and windows brings great inconvenience to production and life, and if the window film pasted on the glass surface of the car does not have the anti-fog function, especially after fogging in bad weather, it will make the driver blurred vision, which brings great hidden dangers to safety. The current anti-fog methods mainly include electric heating and the use of anti-fog coatings. The former is effective but expensive and wastes resources.
