[0004] Sandwich panels are mainly used in the fields of building maintenance structures such as wall panels, roof panels, and ceilings. The core materials commonly used are rock wool boards, XPS boards, slag wool boards, and glass fiber boards. Among them, rock wool boards are mainly The artificial inorganic fiber is made of basalt through high-temperature melting process. It is light in weight, but it is not safe, low in strength and not environmentally friendly. XPS board is made of polystyrene resin as raw material plus other raw and auxiliary materials and Polymer, through heating and mixing while injecting a catalyst, then extruding and extruding a rigid foam plastic board. The XPS board with this structure has extremely low water absorption, but its strength is not high enough and its fire resistance is poor; slag wool The board is made of cotton silk-like inorganic fiber made by high-speed centrifugal method or blowing method, which has poor fire resistance, low strength and low safety performance; It is widely used to form beautiful wall and ceiling decorations, but there are still some shortcomings, such as no safety, low strength and no environmental protection; these commonly used core materials have low safety performance, poor fire resistance, and high strength. Low, not enough environmental protection, it is difficult to meet the needs of the production process
