Composite release film

Abstract

The invention discloses a composite release film which comprises a base layer and a release layer, the surface of the base layer is connected with the release layer, the surface of the release layer is sequentially connected with a first functional layer, an isolating layer, a second functional layer and a protective layer, the first functional layer comprises a shielding layer, one side of the shielding layer is connected with a first bonding layer, and the other side of the shielding layer is connected with a second bonding layer. One side of the shielding layer is connected with a first functional layer, the other side of the shielding layer is connected with a buffer layer, the second functional layer is an antistatic layer, the surface of the antistatic layer is provided with a plurality of convex hulls, rubber particles are filled among the convex hulls, the isolation layer is a tensile layer, and two ends of the tensile layer are respectively connected with a first glass fiber layer and a second glass fiber layer. According to the invention, a plurality of functional layers are integrated in the release film, so that the release film has most use requirements.

Description

technical field [0001] The invention relates to the technical field of release films, in particular to a composite release film. Background technique [0002] Release film, also known as peeling film, isolation film, separation film, barrier film, release film, film, plastic film, pore masking film, silicone oil film, silicone oil paper, anti-adhesive film, type paper, slip film, Tianna paper , release paper, non-woven fabric film, 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 silicon release agent on the surface of the film material, such as PET , PE, OPP, etc.; it can show extremely light and stable release force for various organic pressure-sensitive adhesives (such as hot-melt adhesives, acrylic adhesives, and rubber-based pressure-sensitive adhesives). The release force of the release film is required. The viscosity of the isolation product glue is different, and...

Problems solved by technology

[0003] The existing release film is in use. With the development of science and technology, the release film is used more and more in the society. However, the existing release film is often developed for specific fields. Targeted products, when When the demand for the product is small, it is often applied from other sources because of the high production cost, resulting in the applied product not being able to meet the needs of use.
