Dual-opening heat insulation fireproof door and preparation method thereof

Abstract

The invention discloses a dual-opening heat insulation fireproof door which comprises a door skeleton and door leaves. The door leaves are connected with the door skeleton through a fireproof hinge. Asealing piece is arranged at the contact position of the door leaves. A door closer and a sequencer are connected between the door leaves and the door skeleton, an inner skeleton is arranged inside the door leaves, the door leaves are divided into a plurality of regions through the inner skeleton, the inner skeleton is filled with expanded perlite, an extra-fine glass wool board is adhesively connected to the surface of the expanded perlite, phenolic foam plastics are adhesively connected to the surface of the extra-fine glass wool board, and a gluing fireproof board is adhesively connected to the surface of the phenolic foam plastics. Fireproof doors are closed in sequence, the phenomenon that the fireproof doors collide with each other is avoided, the expanded perlite is arranged insidethe fireproof doors, the fireproof effect is improved, the sealing piece is arranged between the door leaves, the phenomenon that flames run out can be effectively avoided, and the fireproof performance of the fireproof door is greatly improved.

Description

technical field [0001] The invention belongs to the field of door panel installation, and in particular relates to a double-opening heat-insulating fire door and a preparation method thereof. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc.; in addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. Prevent the spread of the fire, ensure the evacuation of personnel, and ensure personal safety. [0003] Fire doors are widely used in practice and are welcomed by people. However, during the use of fire doors, due to the large gap between the door leaves, when a fire breaks out, the flames will come out, which is easy to hurt people, and the existing ...
