Forming method of fireproof safety door

Abstract

The invention discloses a forming method of a fireproof safety door, which is carried out according to the following steps: (1) firstly putting a door leaf of the fireproof safety door on a fixed plate and fixing a hinge side of the door leaf on the fixed plate; (2) uniformly stirring fillers of the fireproof safety door in a stirrer, pouring the fillers into a door plate of the fireproof safety door according to the size of the door body and carrying out prepressing on a cold pressing machine in a compression ratio of (9 to 10):5, wherein after prepressing, the thickness of a pearlite fireproof door core is consistent with that of an inner door leaf; (3) coating a polyurethane adhesive in an outer door plate of the fireproof door and then covering the outer door plate on the filled innerdoor plate; and (4) in the hot pressing process, maintaining the temperature of the pearlite fireproof door between 100 and 110 DEG C, maintaining the hot pressing time for 30 minutes, putting the pearlite fireproof door in an oven to bake and naturally cooling the fireproof door after the fireproof door is discharged from the oven. The forming method makes the fillers of the fireproof safety door directly formed in the door plate by improving the fillers of the fireproof door so as to improve the overall efficiency of production of the fireproof door and improve the overall intensity of the fireproof door.

Description

technical field [0001] The invention relates to a fire safety door, in particular to a forming method of a fire safety door. Background technique [0002] In the current production process of fire safety doors, perlite finished boards are directly placed in the fire door panels. Due to the limitation of perlite board molds, the specifications are not easy to change, and the door body size is made according to customer requirements. Two The latter cannot be unified in matching, so that it takes a lot of time to cut the perlite board. To use perlite boards to fill door panels, it is necessary to make perlite boards first and then dry them at high temperature, which is an independent production process for the overall production of the door body. On the other hand, after the perlite board is placed for a period of time, the surface will produce debris and dust due to weathering, which will pollute the environment and affect the health of workers; secondly, it will increase the...

Problems solved by technology

On the other hand, after the perlite board is placed for a period of time, the surface will produce debris and dust due to weathering, which will pollute the environment and affect the health of workers; secondly, it will increase the difficulty of connecting the perlite board to the door when the door is filled. It makes it difficult to bond the perlite board and the door body, resulting in problems such as slag dropping, degumming, and even board fracture.
