Abstract

The invention discloses a manufacture method of a fireproof door. The manufacture method of the fireproof door includes the following steps: (1) coating the interior of a die of a door with cementing material (A) used as a surface layer of the door; (2) coating a bottom surface layer formed in the step (1) with ping-pong-table-shaped cementing material (B) used as a skeleton of the door; (3) pouring cementing material (C) in a female die after the step (2); (4) covering the female die with the flat die in the step (1), closing the dies by using 2-4 tons of pressure, and splitting the dies after solidification so as to obtain the fireproof door. The manufacture method of the fireproof door has the advantages that improvement of fire prevention and heat shielding properties is improved in the step of raw material ingredient selection, and due to affinity and seamless connections of the three types of the cementing material, the problem that a heat bridge phenomenon occurs when an existing door is manufactured is solved.

Description

technical field [0001] The invention belongs to the technical field of the building field, in particular to a method for making a fireproof door. Background technique [0002] At present, the known fire door categories include wooden fire doors, steel fire doors, steel-wood fire doors and the like. From the analysis of the existing production process of fire doors, the main raw materials of fire doors are steel and wood. Steel has a high melting point and high thermal conductivity, and wood is combustible. If it has the ability of fire prevention and heat insulation, in order to make it have the function of fire prevention and heat insulation, it must be treated with the key process of heat insulation and flame retardancy. The practice of steel fire doors is: use steel materials to make the door frame, door frame and door panel. The key process is to fill the door core with non-toxic and harmless fire-proof and heat-insulating materials. The practice of wooden fire doors i...
