[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fireproof partition with a certain fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. There are many types of fire doors at present. In addition to the fireproof and flame-retardant functions, they also have the functions of heat insulation and sound insulation. However, the sound insulation effect of existing heat insulation and sound insulation fire doors is average. In order to improve their sound insulation effect, many manufacturers use the method of stacking multiple layers of sound insulation boards to improve the sound insulation performance. However, the multi-layer board structure has the problems of poor integrity, insufficient structural strength and poor stability, which can easily cause deformation of the door body. Therefore, for such problems of heat insulation and sound insulation fire doors, how to enhance the integrity and stability of the multi-layer structure, improve the structural strength and also have good heat insulation and sound insulation effects is an urgent problem to be solved.
