Problems solved by technology

[0004] However, most of the current explosion-proof panels are made of steel plates, relying on high-strength materials to resist the impact force. This kind of steel explosion-proof panels is heavy and prone to deformation after encountering fire. It is easy to cause difficulty in opening the fire door in case of fire.

Abstract

The invention relates to a manufacturing process of a fireproof and explosion-proof door, and belongs to the technical field of fireproof doors. The manufacturing process of the fireproof and explosion-proof door comprises the following steps that (1) a wooden door framework is impregnated in flame-retardant impregnation liquid, taken out and dried, and an impregnated door framework is manufactured; (2) a fireproof plate layer is bonded to one side of the impregnated door framework, a filling space is defined by the corresponding surfaces of the impregnated door framework and the fireproof plate layer, then a flame-retardant material is arranged in the filling space, a first flame-retardant layer is formed, a core material is arranged on the first flame-retardant layer, a core layer is formed, then the flame-retardant material is arranged on the core layer, and a second flame-retardant layer is formed; then a fireproof plate layer is bonded to the other side of the impregnated door framework; wherein the core material comprises perlite, and the flame-retardant material comprises silicon dioxide aerogel; and (3) flame-retardant density plates are bonded on the outer surfaces of thefireproof plate layers on the two sides of the impregnated door framework, and pressing is conducted to obtain the fireproof and explosion-proof door. The fireproof and explosion-proof door prepared by the manufacturing process is less in weight and has good fireproof and explosion-proof performance.

Description

technical field [0001] The present application relates to the technical field of fire doors, in particular to a manufacturing process of fire and explosion-proof doors. Background technique [0002] In recent years, with the improvement of fire protection standards for high-rise buildings, fire doors have become more and more widely used in buildings. Fire doors are doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. They are mainly used for firewall openings in building fire compartments, stairwell entrances and exits, evacuation walkways, pipe wellheads, etc., and are usually used for personnel passage. , in the event of a fire, it can prevent the flame from spreading. Since different application fields have different performance requirements for fire doors, various functional fire doors have appeared on the market, such as fire doors with explosion-proof performance, which can reduce the damage...
