Problems solved by technology

[0003] The key component unit in fire doors that can achieve fire resistance, heat insulation, and smoke resistance is the fire door core. Nowadays, there are many products about fire door cores on the market. At present, the door core filling materials include vermiculite and aluminum silicate. Cotton and perlite fireproof board, the rock wool and aluminum silicate in it will cause dust pollution and seriously endanger people's health, while perlite has good fireproof effect, but its price is high, its density is high and dust will be generated during production
[0004] CN201367830Y discloses a novel fireproof door core, which includes a frame body, a filling plate and a panel. A number of filling plates are arranged in the frame, and the gaps between adjacent filling plates are coated with fireproof glue. The front and back of the door are sealed with panels by fireproof glue; the filling plate is irregularly shaped leftover glass magnesium fireproof lath or glass magnesium fireproof board, but the structure of the fireproof door core is complex
[0005] CN202325119U discloses a high-strength fireproof door core board with compact structure, high strength, and stable fireproof and heat insulation properties. A layer of fireproof fiber mesh is laid vertically and horizontally between the pearlite door core boards. Two layers of perlite fireproof boards sandwich the fireproof fiber mesh in the middle to form a whole door core board. The corner frame of the quality door core board is fixedly connected, but the structure of the fire door core is complex
[0006] CN206636445U discloses a door core board structure of a fireproof door, comprising a fireproof door bezel, intersecting reinforcing ribs, and a fireproof substrate; the interior of the fireproof door bezel is provided with intersecting reinforcing ribs, and the interior of the intersecting reinforcing ribs is provided with a fireproof substrate; The middle of the base plate is provided with a perlite fireproof board, the upper end of the perlite fireproof board is connected with a reinforcement board through rivets, and the upper end of the reinforcement board is provided with a metal decorative board; the lower end of the perlite fireproof board is provided with a grid prestressed board, and the grid prestressed board The lower end of the stress plate is provided with a metal panel, but the structure of the fire door core is complex
