Abstract

The invention discloses a double-sided antistatic ultra-light PET release film and a preparation method thereof. The release film includes a PET base film layer, and the PET base film layer is coated with an antistatic coating on both sides, and one side is coated with an antistatic coating. A release layer is coated on the layer, wherein the release agent used in the release layer comprises the following raw materials in parts by weight: 90-110 parts of methyl vinyl siloxane polymer, 20-30 parts of silicon dioxide dilution , non-reactive octamethylcyclotetrasiloxane polymer 25-35 parts, silane coupling agent 20-30 parts, composite organofunctional siloxane 12-20 parts, platinum catalyst and vinyl siloxane polymer 20-30 parts of the mixture and 350-500 parts of the organic solvent, the release layer of the present invention is evenly coated, the product has excellent antistatic effect, the release force and antistatic value are stable under normal temperature and high temperature conditions, and the product stability is better.

Description

technical field [0001] The invention relates to the technical field of optical film materials, in particular to a double-sided antistatic ultra-light PET release film and a preparation method thereof. Background technique [0002] The release film refers to a film with a separable surface. According to the material, it can be divided into: PET release film, BOPP release film, PTFE release film, PMP release film, etc. PET release film is a film with PET as the base material and a layer of release agent on its surface. It is not sticky or slightly sticky after contacting with specific sticky materials under limited conditions. PET release film The film has the advantages of excellent physical and mechanical properties, small thickness tolerance, high transparency, low heat shrinkage, good flexibility, etc. It has been widely used in electronic materials, automotive foam, printing and other fields. sticky materials together, especially tape products. [0003] The release film...
