Problems solved by technology

[0003] However, the protective films currently on the market have a single function, and antibacterial screen protective films are relatively rare.
The common preparation method of antibacterial film is the sol-gel method. Basically, the antibacterial agent is directly added and mixed during the film production process, and the antibacterial film is polymerized by chemical synthesis. This method takes a long time and requires harsh conditions. The dosage is large, and after a period of time, the hydrophilic polar groups on the surface of the antibacterial film will flip over and sneak into the interior of the matrix, resulting in a gradual decrease in the hydrophobicity of the surface and forming the environment required for bacterial growth.

Abstract

The invention relates to the technical field of protective films, in particular to an anti-microbial and anti-static complex film. The anti-microbial and anti-static complex film comprises a protective film, a protective adhesive layer, a use film layer, a stripping adhesive layer and a stripping film, wherein the protective film, the protective adhesive layer, the use film layer, the stripping adhesive layer and the stripping film are arranged in sequence from top to bottom; the upper surface of the protective adhesive layer is attached to the protective film, and the lower surface of the protective adhesive layer is attached to the use film layer; the upper surface of the stripping adhesive layer is attached to the use film layer, and the lower surface of the stripping adhesive layer is attached to the stripping film; the use film layer comprises an anti-microbial and anti-static functional layer and a base film, and the anti-static functional layer and the base film are arranged in sequence from top to bottom; the upper surface of the anti-microbial and anti-static functional layer is attached to the lower surface of the protective adhesive layer, and the lower surface of the anti-microbial and anti-static functional layer is attached to the upper surface of the base film; the lower surface of the base film is attached to the upper surface of the stripping adhesive layer. The complex film has both a good anti-microbial effect and a good anti-static effect, and is diversified in function, simple in structure, low in production cost and high in practicability.

Description

Technical field [0001] The invention relates to the technical field of protective films, in particular to an antibacterial and antistatic composite film and a preparation method thereof. Background technique [0002] With the development of technology, touch screens have become popular in every corner of our daily lives. Now people not only pay attention to the drop-proof and scratch-resistant function of the screen protective film, but also have increasing requirements for clean, safety and environmental protection. Promote the protective film to have a broader market. [0003] However, the protective film currently on the market has a single function, and antibacterial screen protective film is relatively rare. The general preparation method of antibacterial film is the sol-gel method. Basically, the antibacterial agent is directly added and mixed during the film production process, and the antibacterial film is polymerized by chemical synthesis.
