Abstract

The invention discloses a PET(Polyethylene terephthalate) release film for OCA (optically clear adhesive). The PET release film comprises a basic film layer and a release layer; the release layer is arranged on the upper surface of the basic film layer; the release layer is formed by coating release agent and comprises, by mass, 30-45 parts of polyurethane resin, 22-38 parts of butyl acrylate, 20-34 parts of polyethylene glycol, 18-26 parts of nano-silica, 12-23 parts of silicon oxide, 16-24 parts of aluminium oxide, 14-25 parts of polyethylene wax powder, 15-30 parts of polyethylene, 13-18 parts of polyurethane, 11-15 parts of polyimide, 7-16 parts of calcium stearate and 9-18 parts of additives. The PET release film has low release force and has excellent abrasion resistance and waterproofing property.

Description

technical field [0001] The invention relates to the technical field of release films, in particular to a PET release film used for OCA optical glue. Background technique [0002] PET release film, also known as thermal transfer film, peeling film, isolation film, slip film, thinner paper, silicone oil film, anti-adhesive film, silicone oil release paper, silicone oil paper and hole masking film, is mainly used for vacuum aluminum plating The carrier is to place the PET film in a vacuum aluminum plating machine after aluminizing, apply glue and compound it with paper, then peel off the PET film, and the aluminum molecular layer will be transferred to the surface of the cardboard through adhesive action to form the so-called aluminized cardboard. At present, the waterproof performance and wear resistance of the release film on the market are not very satisfactory, which brings inconvenience to users. Therefore, it is necessary to improve the traditional release film. Content...
