Extremely-high-conductivity release film and preparation method thereof

Abstract

The invention discloses a release film with extremely high conductivity. The formula of the release agent comprises the following components in parts by weight: 45-54 parts of silicone oil A, 46-52 parts of silicone oil B, 2-3 parts of a bridging agent, 2-3.5 parts of an adhesion promoter, 1.5-2.8 parts of a catalyst, 130-150 parts of n-heptane, 90-110 parts of D30, 45-52 parts of isopropanol and58-65 parts of cyclohexanone. The base material of the release film is subjected to a sputtering treatment; the release film is suitable for releasing and die cutting punching of various adhesive materials, is generally suitable for adhesion processing of protective films, double faced adhesive tapes and other adhesive materials, and has the advantages of high cleanliness, stable release force, high residual adhesion rate, favorable surface flatness, favorable machining property and extremely low surface resistance.

Description

technical field

[0001] The invention relates to a very high conductivity release film and a preparation method thereof. Background technique

[0002] The release film is also called the release film, which refers to a film with a separable surface. The release film is not sticky or slightly sticky after contacting with a specific material under limited conditions. Usually, in order to increase the release force of the plastic film, the plastic film will be treated with plasma, or coated with fluorine, or coated with a silicone release agent on the surface of the film material, such as PET, PE, OPP, etc., to make it For various organic pressure-sensitive adhesives, such as hot-melt adhesives, acrylic adhesives and rubber-based pressure-sensitive adhesives, it can exhibit extremely light release force. However, the existing release films often have the problems of high surface resistance and poor release stability. Contents of the invention
