[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5, the utility model provides a technical solution: a high-temperature and pressure-resistant protective film, which includes a PE base film 1, an adhesive layer 2, a lower adhesive layer 3, a fireproof partition layer 4, a positioning buckle edge 5, an adhesive positioning layer 6, a protective net layer 7, vertical support columns 8 and a surface coating layer 9. The bottom surface of the PE base film 1 is provided with the adhesive layer 2, the top surface of the PE base film 1 is provided with the lower adhesive layer 3, a fireproof partition layer 4 is installed in the middle of the top surface of the lower adhesive layer 3, the edge of the lower adhesive layer 3 is connected to the bottom end of the positioning buckle edge 5, the positioning buckle edge 5 is arranged outside the fireproof partition layer 4, the top of the positioning buckle edge 5 is provided with the adhesive positioning layer 6, and the protective net layer 7 is fixed on the surface of the adhesive positioning layer 6. The top surface of the protective net layer 7 is provided with the surface coating layer 9.

[0022] In this example, the fireproof partition layer 4 is made of metal flakes, and the thickness of the fireproof partition layer 4 is not greater than half of the thickness of the PE base film 1. The above structural design enables the fireproof partition layer 4 to have strong fireproof ability, is not easy to burn, can avoid the combustion damage of the inner structure of the fireproof partition layer 4, and improves the overall high-temperature resistance performance of the protective film.

[0023] The length and width of the top window of the positioning buckle edge 5 are both smaller than the length and width of the fireproof partition layer 4, and the front view cross-sectional shape of the edge of the positioning buckle edge 5 is an "L" shape. The above structural design enables the positioning buckle edge 5 to be buckled on the edge of the fireproof partition layer 4 to stably position the fireproof partition layer 4.

[0024] The bottom end of the positioning buckle edge 5 is inserted into the top edge of the lower adhesive layer 3, and the vertical part of the inner wall of the positioning buckle edge 5 is closely attached to the side surface of the fireproof partition layer 4. The above structural design ensures the structural strength of the connection between the lower adhesive layer 3, the fireproof partition layer 4 and the positioning buckle edge 5, and ensures the stability of the overall structure.

[0025] The front view cross-section of the adhesive positioning layer 6 is a "T" shape. The bottom of the adhesive positioning layer 6 is arranged in the top window of the positioning buckle edge 5, and the bottom surface of the adhesive positioning layer 6 is attached to the top surface of the fireproof partition layer 4. The above structural design enables the adhesive positioning layer 6 to integrally connect the positioning buckle edge 5 and the fireproof partition layer 4, and further enhances the connection tightness between the fireproof partition layer 4 and the positioning buckle edge 5.

[0026] The thickness of the protective net layer 7 is not less than half of the thickness of the fireproof partition layer 4. Vertical support columns 8 are vertically installed through the protective net layer 7. The above structural design improves the scratch resistance and pressure resistance performance of the protective film.

[0027] The vertical support columns 8 are solid copper columns, and the vertical support columns 8 are arranged at equal intervals in a dense manner. The above structural design enables the vertical support columns 8 to cooperate with the protective net layer 7 to stably protect the protective film and avoid damage to the lower structure caused by excessive extrusion.

[0028] The thickness of the surface coating 9 is not less than 1 / 3 of the thickness of the protective mesh layer 7. The protective mesh layer 7 is made of fine metal wires crossing each other. The above structural design enables the surface coating 9 to ensure the tightness of the overall protective mesh layer 7 and the vertical support columns 8, and cooperate to protect the top of the protective film as a whole with the protective mesh layer 7 and the vertical support columns 8.

[0029] Working principle: The fireproof partition layer 4 and the positioning buckle edge 5 made of metal are not easily combustible, which can isolate the influence of external high temperature on the PE base film 1, ensure the overall stability of the PE base film 1, and cooperate with the full-coverage protection mechanism composed of the top protective mesh layer 7, the vertical support columns 8 and the surface coating 9, which can effectively prevent the protective film from being scratched, enhance the overall structural strength of the protective film, improve the compressive performance of the protective film, avoid damage to the protective film during the extrusion process, and greatly extend the service life of the protective film. This is the working principle of the high-temperature and pressure-resistant protective film.
