Anti-static and anti-blue-light PU adhesive protective film

Abstract

The invention relates to an anti-static and anti-blue-light PU adhesive protective film. The anti-static and anti-blue-light PU adhesive protective film comprises a bottom film, a PET original film layer, an anti-static liquid layer and an anti-blue-light PU adhesive layer, wherein the PET original film layer, the anti-static liquid layer and the anti-blue-light PU adhesive layer are sequentially arranged on the bottom film from top to bottom, the bottom film is a PE release film, and an alkali-resisting layer is arranged on the PET original film layer. According to the anti-static and anti-blue-light PU adhesive protective film, the anti-static liquid layer and the anti-blue-light PU adhesive layer have the effects of preventing static and blue light, while dust and impurity adsorption is avoided, and damage to eyes when people use equipment is reduced to the minimum; the alkali-resisting layer is arranged on the PET original film layer, the PET original film layer is prevented from being damaged by corrosion of alkaline substances, the service life of the product is prolonged, and the using effect is ensured.

Description

technical field [0001] The invention belongs to the technical field of protective films, and in particular relates to an antistatic and anti-blue light PU adhesive protective film. Background technique [0002] With the rapid development of consumer electronics, various protective films have become an indispensable product for protecting touch-type capacitive screens of electronic products such as smart phones and tablet computers. [0003] Most of the protective films currently used in the market are made of PET substrates. Since the resistivity of PET materials is generally as high as 1010-1020Ω·cm, it is easy to accumulate static electricity, so it is easy to absorb dust and impurities during production and use. The base material of PET is not resistant to alkali. If it encounters alkaline substances during use, it will be easily corroded, and the existing electronic equipment will also produce blue light during use, which will also cause great harm to the human body.

[0003] Most of the protective films currently used in the market are made of PET substrates. Since the resistivity of PET materials is generally as high as 1010-1020Ω·cm, it is easy to accumulate static electricity, so it is easy to absorb dust and impurities during production and use. The base material of PET is not resistant to alkali. If it encounters alkaline substances in use, it is easy to be corroded, and the existing electronic equipment will produce blue light during use, which will also cause great harm to the human body.
