[0039] 1. The scratch-resistant layer 11 is an adhesive layer with glass fibers. In addition, a silicon carbide coating can be coated on the outer side of the scratch-resistant layer 11 to effectively enhance the hardness of the release paper 1 and play a certain wear-resistant role. A plurality of raised strips 17 are arranged on the outer side surface of the scratch-resistant layer 11, and the raised strips 17 are linear strips or wavy strips.

[0040] 2. The first heat-insulating layer 12 is a heat-insulating film, and the heat-insulating film is composed of multiple layers of aluminized polyester films.
