Problems solved by technology

[0002] Mobile phone film is usually used to beautify the mobile phone, and at the same time protect the LCD screen of the mobile phone. As we all know, with the development of the economy and the continuous improvement of people's living standards, smart phones have become an indispensable tool in people's lives. Smart phone screens Made of glass, it is fragile and not resistant to scratches, which affects the service life of the mobile phone. Therefore, tempered glass mobile phone film has become a necessity;
[0003] However, today's smart phones use large-screen touch screens, and various operations are performed on the mobile phone through human fingers. Because there are many bacteria on the hands, it is easy to contaminate the mobile phone film. Due to the particularity of electronic products, washing and other methods cannot be used. Clean, so it is often easier to breed various bacteria on the mobile phone film, resulting in worrying about the hygiene of the mobile phone, which in turn affects the health of the user;

Abstract

The invention discloses an antibacterial sanitary mobile phone film and a preparation method thereof, and relates to the field of mobile phone films.The preparation method comprises the steps that an antibacterial antifouling emulsion, a curing agent, a cosolvent, deionized water, a coalescing agent, a flatting agent, a coupling agent and a defoaming agent are stirred to be uniform, then standing and filtering are conducted, and antibacterial sanitary coating is obtained; the antibacterial sanitary coating is sprayed to a rectangular glass sheet subjected to ultrasonic cleaning, an antibacterial sanitary coating is formed after drying, finally, rubberizing is carried out, packaging is carried out after inspection is qualified, and the antibacterial sanitary mobile phone film is obtained. The antibacterial and antifouling emulsion is formed by polymerization of four monomers including methyl methacrylate, butyl acrylate, an intermediate 3 and an intermediate 5, the intermediate 3 endows the antibacterial and antifouling emulsion with good stain-resistant and self-cleaning effects, a formed coating is not prone to being contaminated by stains and easy to clean, and the intermediate 5 endows the antibacterial and antifouling emulsion with good antibacterial and antiviral performance, so that the antibacterial and antifouling emulsion is good in anti-fouling and self-cleaning effects. Therefore, bacterium breeding is avoided, and the cleanliness of the mobile phone film is guaranteed.
