Problems solved by technology

In the traditional technology, the surface of the protective film is smooth. When the machine is automatically pasted, the protective film tends to have residual air, which is not completely discharged, and remains between the materials to be protected, resulting in air bubbles, which prevents the protective film from being perfectly flattened, affecting Product quality; in addition, after the protective film is torn off, there will be bubble marks in the place where the bubbles are formed, and there may be residual glue after a long time, which will affect the quality and appearance of the product

Abstract

The invention relates to a double-sided UV adhesion-reducing film and a preparation method thereof. The double-sided UV adhesion-reducing film comprises a first organic silicone release film layer, afirst ultraviolet adhesion-loss acrylic acid adhesive layer, a flexible base material layer, a second ultraviolet adhesion-loss acrylic acid adhesive layer and a second organic silicone release film layer. The preparation method of the adhesion-reducing film comprises the following steps: uniformly coating a first ultraviolet adhesion-loss acrylic acid adhesive and a second ultraviolet adhesion-loss acrylic acid adhesive on both side faces of a flexible base material by adopting a slit coating technology; pasting first organic silicone release film on the formed first ultraviolet adhesion-lossacrylic acid adhesive layer; and pasting second organic silicone release film on the formed second ultraviolet adhesion-loss acrylic acid adhesive layer film to form the double-sided UV adhesion-reducing film. Two sides of the double-sided UV adhesion-reducing film are respectively provided with the first ultraviolet adhesion-loss acrylic acid adhesive layer and the second ultraviolet adhesion-loss acrylic acid adhesive layer, the acrylic acid adhesive layers are easy to paste, and the adhesion of an ultraviolet adhesion-loss acrylic acid adhesive is reduced from high adhesion to low adhesionafter illumination by using ultraviolet light, so that adhesion-reducing film can be stripped from the surface of a material easily, no residual bubble exists, and the yield of product is greatly improved.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a double-sided UV anti-adhesive film used in the production and processing of protective glass coatings and a preparation method thereof. Background technique [0002] During the coating process of materials such as metal plates, plastic plates, touch screens, multilayer ceramic films, wafers, and glass, the surface of the material is prone to contact pollution or scratches, so a protective film is usually used to cover the surface of the material. protect it from damage and contamination. After the coating process, the protective film will be stripped and removed manually or by robots. In the traditional technology, the surface of the protective film is smooth. When the machine is automatically pasted, the protective film tends to have residual air, which is not completely discharged, and remains between the materials to be protected, resulting in air bubbles, which pr...
