[0002] Aluminum silicate, expanded perlite, vermiculite, polyurethane foam, sulphoaluminate cement foam and other fireproof materials are currently used to make fireproof door core panels. After long-term use, it has been proved that the main reason is that the fireproof door has a heavy load and a short service life. , poor fireproof and waterproof performance, and high production cost; the above-mentioned raw materials are inorganic fibrous harmful substances, and scientific identification proves that long-term contact with such substances will cause people to suffer from silicosis, cancer and other diseases; the above-mentioned raw materials are used by foam molding Foaming agents such as polyurethane, polystyrene, and sulfoaluminate rock cement, and adhesives such as urea-formaldehyde resin, benzaldehyde resin, vermiculite glue, perlite glue, acrylic glue, polypropylene glue, and polyurethane glue used in pressure molding They also contain harmful substances and pose hazards to humans and the environment.

Comprehensively, the existing fire door core boards have the disadvantages of great harm to the human body and the environment, high cost, poor sound insulation effect, low strength, and low service life.
