Abstract

The invention discloses a static-free screen protection film which comprises a scratch resistant layer protection film PET (polyethylene terephthalate) substrate, a protection film adhesive layer, a scratch resistant layer, a composite main film PET substrate, a mounting adhesive layer and a mounting adhesive protection film PET substrate; wherein at least one layer of the mounting adhesive, the composite main film PET substrate layer and the mounting adhesive layer comprises an anionic surfactant. Because at least one layer of the mounting adhesive, the composite main film PET substrate layer or the mounting adhesive layer comprises the anionic surfactant, the static-free screen protection film generates no static, may not adsorb dust, can be widely used as screen protection films of various liquid crystal display screens, and reduces the harm to the human body.

Description

technical field [0001] The invention relates to a protective film, in particular to a non-static screen protective film and a manufacturing method thereof. Background technique [0002] In recent years, with the progress of industrialization, the problem of harm caused by static electricity has been increasing in a wide range of fields from various electronic and electrical equipment, information and communication fields to general daily necessities. Therefore, antistatic in these equipment and industrial places becomes an important issue. [0003] Most of the screen protectors currently on the market are made of PET substrates, so they are prone to static electricity, which not only absorbs dust and impurities, but also damages electrical or electronic component materials, and is also harmful to the human body. [0004] As people have higher and higher requirements for the functions of various protective films, ordinary screen protective films on the market can no longer m...
