[0002] Building materials are various materials used in construction projects, which can be roughly divided into three types: inorganic materials, organic materials and composite materials. Among them, polystyrene foam insulation board is a relatively common composite building material. The insulation board can reduce the thickness of the building's external protective structure and enhance the building's thermal insulation performance;

[0003] The existing document with publication number CN212772907U discloses a thermosetting flame-retardant polystyrene foam composite insulation board, including a fixing frame, a first plywood, a second plywood, a composite insulation component, an outer package component and an inner package component;
