Abstract

The invention relates to a high-adherence anti-static release film, belonging to the field of plastic thin films. The high-adherence anti-static release film comprises a base material layer, wherein the base material layer is coated with an anti-static layer; the anti-static layer is formed by coating anti-static liquid, and is coated with a release layer; the release layer is formed by coating a release agent; the release agent consists of the following components in percentage by mass: 5-30 percent of vinyl end group organic silicon resin, 0.3-5 percent of a bridging agent, 0.5-8 percent of a platinum catalyst, 5-50 percent of methylbenzene and 50-80 percent of ethyl acetate. The release film disclosed by the invention is high in anti-static property and high in adherence (the subsequent adhesion); the release force can meet requirements of some high-end electronic materials; the anti-static layer has an anti-static function and can enhance connection with the release layer, so that the anti-static layer is unlikely to fall; the film is high in firmness and durable; all the layers are tightly connected and are unlikely to separate; the manufacturing cost is low, and the technology is simple.

Description

technical field [0001] The invention belongs to the field of plastic films, and relates to a release film, in particular to a high-adhesion antistatic release film. Background technique [0002] The release film includes a base film and a release layer. The base film is mostly made of paper or plastic film, and the release layer is mainly composed of silicon mixture. Generally, it is mostly used for industrial adhesive tapes (or adhesive tapes), etc. The requirements for the release film are relatively low, and only high adhesion and residual adhesive rate are required. However, as the release film is used more and more widely, There are also certain requirements for its antistatic performance. High adhesion, that is, high residual adhesion rate and anti-static effect-these two items are currently in the IT fields of mobile phones, LCDs, semiconductors, and displays. The requirements are higher than before. For this reason, Quanmin has been committed to researching anti-s...
