[0002] With the development of society, people's living standards are constantly improving, people's requirements for indoor environment are getting higher and higher, and more and more types of panels are needed, including thermal insulation panels. Most of the existing thermal insulation panels in the construction field are made by spraying insulation slurry on the surface of the panel.

[0003] The existing publication number CN210316038U discloses a flame retardant heat-insulating board material, comprising a substrate, a heat-insulating layer pasted on one side of the substrate, a gas-barrier layer pasted on the side of the heat-insulating layer away from the substrate, the heat-insulating layer comprising a heat-insulating filler and a porous heat-insulating board, the heat-insulating filler is filled in the holes of the porous heat-insulating board; the heat-insulating filler is expandable graphite; the heat-insulating layer can also be arranged on both sides of the substrate; the gas-barrier layer is a gas-barrier film; the heat-insulating layer is composed of a porous heat-insulating board and expandable graphite, the expandable graphite has good high temperature resistance and fire resistance, and the gas-barrier film is pasted on the heat-insulating layer, the gas-barrier film can ensure the vacuum environment created, and can minimize the heat conduction and convection heat exchange caused by the gas, thereby achieving a better flame-retardant and heat-insulating effect.

In order to further improve the heat insulating effect of the plates, we propose a flame retardant and heat insulating plate. Utility Model Content
