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 provides a photochromic release film. The release film is characterized in that the release film comprises a base film layer, a release layer is arranged on the base film layer, and the release layer is coated by a release agent; the release agent comprises the following components in parts by weight: 15-30 parts of a photochromic compound, 10-20 parts of vinyl silicone oil, 16-30 parts of epoxy resin, 3-8 parts of titanium dioxide, 0.1-3 parts of an anti-oxidant, 2-5 parts of a coupling agent, 0.2-1.8 parts of an antifoaming agent, and 0.1-1 part of an adhesive force promoter, and 20-45 parts of a solvent. Adhesion is not generated during separation between the photochromic release film and a contacted adhesion belt or adhesive tape; at the same time, the release film contains the photochromic compound, when the film is irradiated by ultraviolet ray containing light, such as sunlight, color change of the release film can be visually displayed with caution effects, so that accelerated aging of an adhesive in an external environment such as ultraviolet ray irradiation can be avoided, and usage life of the product is prolonged.

Description

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