AI Technical Summary

Problems solved by technology

Although PE has many advantages, the weather resistance of PVC film is poor, and it is more likely to age under the action of external environments such as light, heat, and oxygen, which affects its scope of use.
At the same time, the current release film has relatively single performance and is usually only used for isolation and filling

Abstract

A disclosed PVC color-variable release film comprises PVC, PA, EVA, CPE resin, PBT, PET, methoxy polyethylene glycol, PTFE, polymethyl methacrylate, polyphenylene sulfide, glass fiber, organic montmorillonite, poly(ether ether ketone) fiber, heat-sensitive red, PVA, dodecanol, chitosan, anti-oxidant 1010, light-stabilizing agent 622, nanometer TiO2, PE-g-MAH, a thickening agent and a coupling agent. The release film possesses extremely excellent waterproofness, corrosion resistance, temperature tolerance, weatherability and binding property, also can change color after being heated, and possesses heat-dissipation energy-storage effects.

Description

technical field [0001] The invention relates to a release film, in particular to a PVC discoloration release film. Background technique [0002] Release film, also known as peeling film, isolation film, separation film, barrier film, release film, film, plastic film, hole masking film, silicone oil film, silicone oil paper, anti-adhesive film, slip film, Tianna paper, release film Paper, silliconfilm, release film, release. 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 (silicone) 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). [0003] Because the release film has the advantages of isolation, filling, protection, and easy peeling, it ...
