Abstract

The invention relates to the technical field of release films, and provides an anti-static anti-ultraviolet modified PET / PC (Polyethylene Terephthalate / Polycarbonate) release film. The release film comprises a base film, an anti-static layer, a release layer and an anti-ultraviolet layer, wherein the base film is a polyester-polycarbonate composite modified film; the anti-static layer is arranged between the base film and the release layer; an anti-static coating is made of ethyl orthosilicate paint; the release layer is arranged on one side of the base film; the anti-ultraviolet layer is arranged on the outer surface of one side free from the release layer of the base film; an ultraviolet absorbent in the anti-ultraviolet layer is a composite ultraviolet absorbent. The base film is prepared by modification and compounding a PET / PC film; the anti-static coating made of the ethyl orthosilicate paint has high conductivity, so that static electricity on the surface of the release film can be carried away, and an anti-static effect is achieved; through synergistic action of the composite ultraviolet absorbent, the anti-ultraviolet property of the PET / PC release film is enhanced greatly.

Description

technical field [0001] The invention relates to the technical field of release films, in particular to an antistatic and anti-ultraviolet modified PET / PC release film. Background technique [0002] Polyethylene terephthalate (PET) is an important engineering plastic with excellent physical and mechanical properties. Polycarbonate (PC) is a tough thermoplastic resin. Modified PET / PC release film is based on PET / PC film, and a layer of silicone oil, also known as silicone oil film, is coated on the surface of PET / PC film to make the surface of PET / PC film smooth, thereby reducing PET / PC film. The tension on the surface of the PC film makes it have better release force and achieve the effect of release. [0003] The conventional thickness of modified PET release film is from 25μm to 150μm. There are hot and cold tear and matte surface, after anti-static and anti-scratch treatment, the product has good adsorption and fit. [0004] Modified PET release film has been widely use...
