Problems solved by technology

[0004] However, the PE release film is rolled into a film tube after the preparation process is completed. If the PE release film tube is exposed to sunlight for a long time during storage, the ultraviolet rays in the sunlight will destroy the chemical bonds of the polymer, making the PE The base film of the material is decomposed, the physical properties decrease, and its tensile strength, elongation at break and elastic modulus all decrease, which affects the normal use of the release film

Embodiment Construction

[0022] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, the anti-ultraviolet aging release film includes a PE base layer 1, one side of the PE base layer 1 is provided with a peeling layer 2, and the other side of the PE base layer 1 is provided with an ultraviolet isolation layer 4, and the ultraviolet isolation layer 4 is connected to the PE base layer 1. The side facing away from each other is provided with a reflective layer 3; the release layer 2 and the PE base layer 1 are bonded by a release agent coating 6; in this embodiment, the outer side of the PE base layer 1 is provided with an ultraviolet isolation layer 4 and a reflective layer 3. The reflective layer 3 is used to reflect sunlight and reduce the absorption of light by the release film. The ultraviolet isolation layer 4 isolates ultraviolet rays, blocks ultraviolet rays ou...

Abstract

The invention provides an anti-ultraviolet aging release film, which comprises a PE base layer. A stripping layer is arranged on one side of the PE base layer, an ultraviolet isolation layer is arranged on the other side of the PE base layer, and a reflective layer is arranged on the side, deviating from the PE base layer, of the ultraviolet isolation layer. The stripping layer and the PE base layer are bonded through a release agent coating; in the embodiment, the ultraviolet isolation layer and the reflective layer are arranged on the outer side of the PE base layer, and the reflective layeris used for reflecting sunlight and reducing light absorption of the release film, so that the aging speed of the release film is reduced; the ultraviolet isolation layer isolates ultraviolet rays and blocks the ultraviolet rays outside, so that the ultraviolet rays are prevented from reaching the PE base layer to protect the PE base layer, the influence of the ultraviolet rays on the PE base layer is effectively avoided, and the aging speed of the PE base film can be remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of release films, in particular to an anti-ultraviolet aging release film. Background technique [0002] The release film is a thin film material that has a good release force when peeling off the surface of the material by setting a release layer on the substrate carrier. Since the release film is easy to peel off, it can effectively improve the efficiency of replacement. Application Wide range of fields. [0003] In the prior art, for example, the Chinese utility model patent with application number CN201920251986.8 discloses a PE milky white release film, which includes a first composition layer, a second composition layer, a third composition layer and an adhesive layer, the first composition The layer is composed of polyethylene, the bottom surface of the first composition layer is attached with the second composition layer, the second composition layer is composed of high-density polyethylene, the bot...
