Anti-static PET (Polyethylene Terephthalate) material membrane as well as preparation method and application thereof

Abstract

The invention discloses an anti-static PET (Polyethylene Terephthalate) material membrane as well as a preparation method and an application thereof. According to the anti-static PET material membrane, the anti-static property is achieved by adding conductive polymers into at least one of a scrap resisting layer, a composite adhesive layer or an installing adhesive layer. The anti-static PET material membrane disclosed by the invention can be widely used for preparing products such as screen protective membranes, solar isolating membranes, IMD ((In-mold Decoration) and wall membranes, the products have the permanent anti-static property, the anti-static property is not weakened or even vanished because of environment change, and the products are free of static electricity and do not absorb dust, so that the membrane can be widely applied to various protective membrane products which have rigorous demands on static electricity generation.

Description

technical field [0001] The invention relates to a protective film, in particular to an antistatic PET material film, a production method and application thereof. Background technique [0002] In recent years, with the development of industry, the problem of harm caused by static electricity is increasing in the fields of electronic equipment, electrical equipment, information communication, etc., as well as general daily necessities. For example, on the operating table, static sparks can cause the explosion of anesthesia, injuring doctors and patients; Interfering with the operation of aerospace vehicles; in the printing factory, the static electricity between the paper sheets will make the paper sheets stick together, making it difficult to separate, causing trouble for printing; in the pharmaceutical factory, due to the static electricity attracting dust, the medicine will not reach When the TV is placed, the static electricity on the surface of the screen is easy to abso...

AI Technical Summary

Problems solved by technology

[0003] Most of the protective films currently on the market are made of PET substrates, because the resistivity of PET materials is generally as high as 10 10 ~10 20 Ω·cm, it is very easy to accumulate static electricity, so it is easy to absorb dust and impurities during production and use. When this protective film is used, it is easy to cause damage to electrical or electronic component materials, and it is also harmful to the human body.

[0004] Because people have higher and higher requirements for the functions of various protective films, and at the same time, in order to overcome the troubles caused by static electricity to users, ordinary protective films on the market can no longer meet people's requirements, so the development of high-performance and diversified protective films Membranes have broad market prospects
