Abstract

The invention relates to a double-side-coated release film. The double-side-coated release film is characterized by comprising a base film layer; two release layers are respectively arranged at the two sides of the base film layer; the release layers are respectively formed by coating a release agent; the release agent is prepared from the following components in parts by mass: 10-20 parts of vinyl organic silicon resin, 15-30 parts of polyethylene glycol terephthalate, 5-10 parts of polyethylene glycol, 1-6 parts of nano silicon dioxide, 3-10 parts of a conductive polymer, 0.1-0.6 part of a low-surface tension auxiliary agent, 1-3.5 parts of a toughening agent, 0.5-1.5 parts of a defoaming agent and 18-30 parts of a solvent. The double-side-coated release film does not produce adhesion when being separated from an adhesion belt or adhesive tape which is in contact with the release film, thus being good in separation effect; furthermore, the double-side-coated release film contains the conductive polymer, thus having very strong antistatic ability; therefore, the double-side-coated release film is wide in application scope.

Description

technical field [0001] The invention relates to a release film, in particular to a double-sided coated release film. Background technique [0002] Release film, also known as anti-adhesive film, is based on polyethylene terephthalate plastic (PET for short), biaxially oriented polypropylene film plastic (BOPP for short), polyethylene plastic (PE for short), and carbonate plastic (PET for short). PC), polystyrene plastic (referred to as PS), polypropylene plastic (abbreviated as CPP) is a material with low surface energy on the surface. When the adjacent adhesive is peeled from the release surface, the release material can be easily peeled off or removed without damaging the physical properties of the adhesive. The release film is characterized by smooth surface, high cleanliness, stable size in subsequent processing, adjustable transparency and color, and a wide range of options for film thickness and substrate types. Utilizing these characteristics of the release film can...
