[0002] With the improvement of people's living standards, modern society has also put forward higher requirements for thermal insulation panels, requiring not only good thermal insulation performance, but also good fire resistance. It is difficult for a single material to meet the requirements of thermal insulation and fire resistance at the same time, or the price of materials that meet both requirements is too expensive to be used in large quantities. Therefore, composite panels have become a better choice. With the country's urbanization strategy, rail transit, as a century-old infrastructure, has developed rapidly. As a population distribution center, rail transit transfer stations have safety as a top priority. As a decorative panel dedicated to rail transit, it must first have excellent fire resistance.

[0003] After searching, the Chinese patent with announcement number: CN214000792U discloses a fireproof metal composite panel, including a plate body, a decorative layer fixedly connected to the surface of the plate body, the plate body including a panel layer, the inner wall of the panel layer is fixedly connected to a fireproof layer, the inner wall of the fireproof layer is fixedly connected to a composite layer, the inner wall of the composite layer is fixedly connected to a bottom plate layer, the composite layer includes an inner core layer, the inner wall of the inner core layer is fixedly connected to a heat insulation layer, and the panel layer is made of a fireproof metal material, and the fireproof metal material is a zinc-magnesium-aluminum alloy. The utility model can effectively solve the problem that the traditional rail transit wall panels cannot effectively resist the humid environment during use, which is easy to affect their service life, through the coordinated use of the plate body, the decorative layer, the panel layer, the fireproof layer, the composite layer, the bottom plate layer, the inner core layer and the heat insulation layer. The wall panels have good thermal insulation and flame retardant properties, reduce the impact of the underground humid environment on the wall panels, and effectively increase the service life.

[0004] The working principle of the above patent mentions that "when in use, the panel layer 101 is made of zinc-magnesium-aluminum alloy and has excellent fireproof and heat-insulating properties, which ensures stability during use. The fireproof layer 102 can further enhance the fireproof performance of the wall panel. The inner core layer 1031 uses one of cement slabs and calcium silicate to improve the convenience of construction. The heat insulation layer 1032 can further enhance the thermal insulation performance. The decorative layer 2 can increase the decorative effect of the panel layer 101 and make it more beautiful." However, if the metal composite panel is used for a long time, it will be affected by temperature and air humidity, which will cause uneven thermal expansion and contraction of the metal and filler or excessive water absorption, thereby causing warping. In view of the above problems, a fireproof metal composite panel is proposed to solve the above problems. Utility Model Content
