High-temperature-resistant release film

Abstract

The invention provides a high-temperature-resistant release film which comprises a base layer, a release agent coating is arranged on one side of the base layer, a heat insulation layer is arranged onthe other side of the base layer, a heat reflection layer is arranged on the side, deviating from the base layer, of the heat insulation layer, a flame-retardant layer is arranged on the side, deviating from the heat insulation layer, of the heat reflection layer, a vacuum interlayer is arranged in the heat insulation layer, the surface layer of the release film is not prone to combustion and hascertain flame retardance, the release film has high heat resistance by means of heat reflection and heat isolation, heat transfer from one side to the other side can be effectively controlled and reduced, and a film-coated product is effectively protected.

Description

technical field [0001] The invention belongs to the technical field of release films, and in particular relates to a high-temperature-resistant release film. Background technique [0002] The release film refers to a film whose surface can be distinguished. The release film is not sticky or slightly sticky after contacting with a specific material under limited conditions. [0003] The existing release film is mainly coated with a release layer on the substrate layer, but there are the following problems: PET / PE release film is generally used as a raw material for other products, and for some products, its strength is low and stable. Poor performance and poor antistatic performance; After the existing release film is used, when the release film needs to be separated, it is generally separated directly from the corner of the release film, but the size of the release film is very thin , the gap between other films and the release film is small, and the adhesion between the tw...

AI Technical Summary

Problems solved by technology

[0003] The existing release film is mainly coated with a release layer on the substrate layer, but there are the following problems: PET / PE release film is generally used as a raw material for other products, and for some products, its strength is low and stable. The problems of poor performance and poor antistatic performance; after the existing release film is used, when the release film needs to be separated, it is generally separated directly from the corner of the release film, but the size of the release film is very thin , the gap between other films and the release film is small, and the adhesion between the two is relatively large. When the release film is torn off from other films, it is prone to damage or incomplete tearing, which is difficult to operate. Start, making the operation less convenient

[0005] However, although the above-mentioned release film has a certain flame-retardant performance, it cannot control the heat transfer in the external combustion environment, and the heat is easily transferred through the release film, which will damage the film-coated product and bring economic losses to the enterprise.
