Problems solved by technology

[0003] The coating film in the prior art generally adopts cold lamination film, the glue adopts pressure-sensitive adhesive, and the surface is covered with release paper, but after a long time, due to the irradiation of ultraviolet light, the pressure-sensitive adhesive turns yellow, so the colorfulness of the pattern is affected. certain influence
Especially for shopping malls or ultrasonic glass, it is wiped almost every day. Therefore, the cold lamination film in the prior art is not resistant to scrubbing and has poor scratch resistance. Often after half a year, there will be many scratches on the protective film, which will affect the quality of the entire promotional pattern. transparency

Abstract

The invention belongs to the technical field of advertising display and decorative materials and particularly relates to a preparation method for an anti-scratch crystal film for surface advertisements. An optical transparent adhesive and a transparent hard coating are firstly prepared; then, a polyester film is coated with silicone oil to form a silicone oil layer, the silicone oil layer is coated with the optical transparent adhesive of 10-30 microns to form an optical transparent adhesive layer, the surface of the optical transparent adhesive layer is covered with a PET film, and drying is performed; then, the PET film is coated with the transparent hard coating to form a transparent hard coating layer, and UV curing is performed; finally, the transparent hard coating layer of the PET film is covered with a protective film, and rolling is performed. The crystal film is excellent in heat aging resistance and ultraviolet light aging resistance performance. In addition, the crystal film has a self-cleaning function and is easy to clean, and dust is not likely to attach to the film. Visible light transmitting rate is 94% or above, and the anti-scratch crystal film can be used for advertising on glass of a shopping mall or a supermarket.

Description

technical field [0001] The invention belongs to the technical field of advertising display and decorative materials, and particularly relates to a preparation method of a scratch-resistant crystal film for surface advertising. Background technique [0002] Today, the advertising industry is growing rapidly, and we can see large commercial advertisements everywhere. Especially in the outdoor or large shopping malls, supermarkets will be sprayed with various advertising patterns on the glass. The color requirements of the promotional pattern are very high, clear, transparent and wear-resistant, which has very high requirements for the coating film on the advertising surface. [0003] The coating film in the prior art generally adopts cold lamination film, the glue adopts pressure-sensitive adhesive, and the surface is covered with release paper, but after a long time, due to the irradiation of ultraviolet light, the pressure-sensitive adhesive turns yellow, so the vividness o...
