Problems solved by technology

[0004] However, most of the traditional release films are transparent, translucent or colored release films. Due to their high transparency, they are not easy to identify. At night or in dimly lit environments, the processing and use of the release film will be affected.

Abstract

The invention relates to a reflecting release film, which is characterized by comprising a base film layer, wherein a release layer is arranged on the base film layer; the release layer is formed by coating a release agent; the release agent is prepared from the following ingredients in parts by mass: 20 to 35 parts of reflecting powder, 10 to 40 parts of vinyl organic silicon resin, 5 to 18 parts of butyl acrylate, 2 to 6 parts of titanium dioxide, 0.1 to 3 parts of antioxidant, 1 to 5 parts of coupling agents, 0.5 to 1.5 parts of defoaming agents and 15 to 30 parts of solvents. The reflecting release film has the advantages that adhesion cannot be generated when the obtained release film is separated from a contact adhesion belt or bonding belt; reflecting powder glass microbeads are added, so that the recognition degree of the release film is enhanced at night or in dark lamp light environment; the processing and the use of the release film are convenient.

Description

technical field [0001] The invention relates to a release film, in particular to a reflective release film and a preparation method thereof. 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...
