Abstract

The invention discloses an antistatic matte non-silicon release film and a preparation method thereof. The release film comprises matte PET, a priming coat, an antistatic layer and a non-silicon release layer distributed from bottom to top; the priming coat layer comprises polyvinyl butyral; the antistatic layer comprises the following components in parts by weight: 500-1000 parts of a mixed solvent, 100 parts of a polythiophene solution, 3-20 parts of N, N-dimethylformamide, 0-10 parts of ascorbic acid and 0-5 parts of an amino acid carboxylic acid chelating agent; and the non-silicon release layer is prepared from the following components in parts by weight: 500 to 1000 parts of methylbenzene, 50 to 500 parts of ketone solvent, 0 to 300 parts of amino modified acrylic resin, 0 to 300 parts of hydroxyl saturated polyester resin and 5 to 50 parts of curing agent.

Description

technical field [0001] The invention belongs to the field of die-cutting processing of release films and electronic products, and in particular relates to an antistatic matte non-silicon release film and a preparation method thereof. Background technique [0002] The release film is a film material coated with a release agent on the film. It is characterized by smooth surface, high cleanliness, stable size in subsequent processing, adjustable transparency and color, and a wide range of film thickness and substrate types. Wide, the release film has no stickiness or slight stickiness after contact with specific materials under limited conditions. [0003] At present, the products on the release film market are generally made of PET film as the base material and silicone oil as the release agent; however, with the development of LCD, LED, PC, mobile phone and other industries, Huawei, Apple and many other companies require release The release film cannot contain any silicon el...
