Problems solved by technology

[0005] Since the surface of the release film needs to be covered with an adhesive, the main material of the adhesive is a high molecular polymer, which is very sensitive to the space environment. The adhesive is in the external environment such as ultraviolet rays, temperature, oxygen, water and pollutants Under the influence, it will accelerate aging, thus affecting the service life of the product

Abstract

The invention relates to a thermochromic release film. The thermochromic release film is characterized by comprising a base film layer; a release layer is arranged on the base film layer and is formed by coating a release agent; the release agent is prepared from the following components in parts by mass: 10-25 parts of a thermochromic compound, 18-30 parts of vinyl organic silicon resin, 1-7 parts of methacrylate, 3-9 parts of titanium dioxide, 0.1-2.5 parts of an antioxidant, 2-7.5 parts of a coupling agent, 0.2-1.8 parts of a defoaming agent, 0.1-1.5 parts of an adhesion promoter and 20-40 parts of a solvent; the thermochromic release film does not produce adhesion when being separated from an adhesion belt or adhesive tape which is in contact with the release film; furthermore, the thermochromic release film contains the thermochromic compound, so that the color of the release film can visually display when the release film is positioned in an environment with overhigh temperature; therefore, the thermochromic release film has a warning function, the accelerated aging of an adhesive is avoided in the external environment such as high temperature, and the service life of a product is prolonged.

Description

technical field [0001] The invention relates to a release film, in particular to a thermochromic 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 devel...
