DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the application clearer, the technical scheme of the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application.

[0023] As shown in the drawings, one embodiment of the application proposes a high-temperature-resistant release paper, which comprises: Figures 1-3

[0024] The double base layer 1 is designed to increase the thickness of the release paper, thereby increasing the structural strength and improving the shrinkage resistance. One side of the double base layer 1 is provided with a film layer 2, and the outer side of the film layer 2 is provided with a silicone oil layer 3. The film layer 2 and the silicone oil layer 3 are both prior art, and the silicone oil layer 3 is connected with the double base layer 1 through the film layer 2.

[0025] ​​The heat insulation film 4 is arranged on the other side of the double base layer 1, and is far away from the coating layer 2. The heat insulation film 4 is a polyester film, which can reduce the conduction of external heat and achieve the effect of heat insulation. The outer side of the heat insulation film 4 is provided with a wear-resistant layer 5, which is a dictionary paper layer. The paper is thin and tough, and the outer side of the wear-resistant layer 5 is provided with reinforcing lines 6, which are convex lines and can improve the structural strength of the wear-resistant layer 5.

[0026] The reinforcing layer 7 is arranged between the coating layer 2 and the heat insulation film 4, and is arranged on the double base layer 1. Through the reinforcing layer 7, the structural strength of the double base layer 1 can be further improved, so that it is not easy to deform in a high-temperature environment.

[0027] The application can effectively improve the structural strength of the release paper by the cooperation of the double base layer 1, the reinforcing lines 6 and the reinforcing layer 7, so as to improve its anti-shrinkage performance, so that it is not easy to shrink and deform in a high-temperature environment, so as to facilitate the normal use of the release paper.

[0028] As shown in Figures 1-3 some embodiments, the double base layer 1 is composed of a longitudinal base layer 8 and a transverse base layer 9 which are adhered to each other. According to the search, since the main component of paper is plant fiber, most of the fibers will arrange along the running direction of the paper machine during papermaking, which is the silk direction of the paper. Generally, for single paper, the longitudinal base layer 8 is a paper with fiber direction parallel to the long side, which is a longitudinal paper, and the transverse base layer 9 is a paper with fiber direction parallel to the short side, which is a transverse paper. The stresses of the longitudinal paper and the transverse paper are different, and the anti-shrinkage performance of the double base layer 1 can be improved by interleaving and stacking the two.

[0029] As shown in Figures 1-3 some embodiments, the reinforcing layer 7 is arranged on the opposite side of the longitudinal base layer 8 and the transverse base layer 9. Such design maximizes the connection area of the reinforcing layer 7, the longitudinal base layer 8 and the transverse base layer 9, so as to improve the strength of the two.

[0030] As shown in Figures 1-3 some embodiments, the reinforcing layer 7 is adhered and fixed to the longitudinal base layer 8 and the transverse base layer 9 by a glue layer. The glue layer is an oily acrylic pressure-sensitive adhesive, which can improve the connection firmness of the longitudinal base layer 8, the reinforcing layer 7 and the transverse base layer 9.

[0031] As shown in Figures 1-3As shown, in some embodiments, the reinforcing layer 7 includes longitudinal connecting strips 10, which are arranged linearly along the length of the reinforcing layer 7. The longitudinal connecting strips 10 are connected by transverse connecting strips 11. The longitudinal connecting strips 10 are arranged linearly along the length of the transverse connecting strips 11. Both the longitudinal connecting strips 10 and the transverse connecting strips 11 are made of ceramic fiber, and the gap between the longitudinal connecting strips 10 and the transverse connecting strips 11 is filled with an adhesive layer. The mesh structure makes the reinforcing layer 7 have high mechanical strength and strong anti-shrinkage performance.

[0032] like Figures 1-3 As shown, in some embodiments, the longitudinal connecting strip 10 and the transverse connecting strip 11 are arranged in a staggered manner. The longitudinal connecting strip 10 is connected to the transverse base layer 9, and the transverse connecting strip 11 is connected to the longitudinal base layer 8. The stress directions of the longitudinal connecting strip 10 and the transverse base layer 9 during deformation are different, and the stress directions of the transverse connecting strip 11 and the longitudinal base layer 8 during deformation are different. By adopting the staggered design, the mechanical strength of the double base layer 1 can be further improved.

[0033] like Figure 1 and Figure 3 As shown, in some embodiments, the reinforcing texture 6 is in the form of a grid, which can improve the mechanical strength of the wear-resistant layer 5 and make it less prone to deformation.

[0034] like Figure 1 and Figure 3 As shown, in some embodiments, the heat insulation film 4 is made using a biaxial stretching process. This design can improve the physical stability and mechanical strength of the heat insulation film 4, making it less prone to shrinkage and deformation.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
