Description
Technical field
This utility model relates to a kind of building material field, is specifically related to a kind of fire resistance steel door.
Background technology
Fire resistance steel door is make doorframe and door-plate of steel material, and is equipped with the door with certain fire resistance that fire prevention Hardware fitting forms.Door leaf includes the counter-fire panel of fireproof core board and fireproof core board both sides, back of the body fire panel, and counter-fire panel, back of the body fire panel are steel plate, and anti-fire door core board is generally perlite fireproof plate.Owing to the heat-insulating, fire-preventing performance of perlite fireproof plate is general, therefore, when a fire, heat is quickly delivered to back of the body fire panel from counter-fire panel through fireproof core board, causing that whole fire resistance steel door temperature quickly raises, therefore, the heat-insulating, fire-preventing performance of existing fire resistance steel door has much room for improvement.
Summary of the invention
This utility model is for the deficiencies in the prior art, it is proposed to a kind of high fire-retardance fire resistance steel door that can improve heat-insulating, fire-preventing performance.
This utility model is achieved through the following technical solutions technical goal.
High fire-retardance fire resistance steel door, including doorframe, door leaf, hinge for fireproof, fire-proof expansion seal strip, the side of door leaf is hinged by hinge for fireproof and doorframe；Described doorframe is steel；Described door leaf includes the counter-fire panel of fireproof core board and fireproof core board both sides, back of the body fire panel；Described counter-fire panel, back of the body fire panel are steel design；The contact surface of described doorframe and door leaf side is embedded with fire-proof expansion seal strip；It thes improvement is that: be provided with complex reflex heat-insulating shield between the counter-fire panel of described door leaf, fireproof core board.
In said structure, described complex reflex heat-insulating shield is inorganic SiO2As interval insulant, aluminium foil as the multi-layer compound structure of sandwich material.
In said structure, described doorframe and door leaf side, counter-fire panel contact surface be embedded with the fire-proof expansion seal strip that cross section is L-shaped, described fire-proof expansion seal strip can simultaneously with door leaf side, counter-fire plate contact.
In said structure, described counter-fire panel, back of the body fire panel are galvanized steel plain sheet, are provided with chemical conversion layer, primary coat, essence coating respectively from inside to outside；Described primary coat is for filtering ethylene priming paint, and essence coating is fire retarding paint.
In said structure, described chemical conversion layer is plating solvent.
This utility model compared with prior art, has the positive effect that:
1. the counter-fire panel of door leaf, be provided with complex reflex heat-insulating shield between fireproof core board, on the one hand owing to complex reflex heat-insulating shield has stronger reflection, on the other hand owing to complex reflex heat-insulating shield heat conductivity is extremely low, therefore, heat-blocking action can be played, improve heat-insulating, fire-preventing effect of the present utility model.
2. doorframe is embedded with, with the contact surface of door leaf side, counter-fire panel, the fire-proof expansion seal strip that cross section is L-shaped, fire-proof expansion seal strip can simultaneously with door leaf side, counter-fire plate contact, significantly improve the sealing of door leaf, doorframe junction on the one hand, on the other hand, the strike note produced of closing the door is substantially reduced.
3. counter-fire panel, the back of the body fire panel on be provided with from inside to outside respectively chemical conversion layer, primary coat, essence coating, significantly improve flame retardant effect.
