Abstract

The invention belongs to the technical field of touch screen protective films, and particularly relates to an antistatic touch screen protective film. The film comprises a release film layer, an adhesive layer, an antistatic layer and a base material layer, wherein the release film layer is a fluorine release film; the antistatic layer is prepared by melting and mixing layered manganese sulfide-cerium dioxide, nickel-polyphenylene sulfide deposited polytetrafluoroethylene and lithium bis(trifluoromethane sulfonimide), then carrying out hot pressing to form a film and then carrying out cold pressing at room temperature; and the base material is a thermoplastic polyurethane elastomer rubber film. The antistatic touch screen protective film has the beneficial effects that the nickel-polyphenylene sulfide is deposited on a polytetrafluoroethylene film through magnetron sputtering, so sheet resistance is reduced, and an antistatic function is realized; and a layered manganese sulfide-cerium dioxide layered structure provides an ion transmission channel, so the antistatic performance of the touch screen protective film is improved.

Description

technical field [0001] The invention belongs to the technical field of touch screen protective films, and in particular relates to an antistatic touch screen protective film and a preparation method thereof. Background technique [0002] As a new computer input device, the touch screen is a simple, convenient and natural way of human-computer interaction. It gives multimedia a new look and is an attractive new multimedia interactive device. It is mainly used in public information In terms of inquiry, industrial control, military command, electronic games, multimedia teaching, etc., when the touch screen is in use, the surface needs to be covered with a protective film to protect the touch screen. [0003] According to the purpose, the protective film can be divided into digital product protective film, car protective film, household protective film, food preservation protective film, etc. With the popularization of digital products such as mobile phones in China, protective ...
