a fireproof board

Abstract

The invention discloses a fireproof board comprising a fireproof board body. The fireproof board body comprises a base plate, a mounting cavity is formed in the middle of the base plate, the inner side end of the mounting cavity is open, and a heat insulation board is installed at the open end of the mounting cavity in a sealing mode. An inflation layer is disposed at the inner side end of the heat insulation board, an inflation chamber is formed in the inflation layer, the inflation chamber is filled with inert gas, more than one gas guiding tube is inserted into the inflation chamber in a sealing mode, and the gas guiding tubes penetrate through the inflation layer. Corresponding inserting holes are formed in the heat insulation board facing the gas guiding tubes, the left ends of the inserting holes run through the right ends of the inserting holes, the extending ends of the gas guiding tubes are inserted into the inserting holes, the outer side ends of the gas guiding tubes form agap layer, the gap layer is internally filled with a flammable sealing layer in a sealing mode, and the gas outlet ends of the gas guiding tubes are sealed by the flammable sealing layer. The fireproof board not only has a quite good heat insulation capacity, but also can effectively prevent fire in a fire, effectively block the spread of the entire fire, can extinguish the fire to a certain extent, and improve the indoor safety.

Description

technical field [0001] The invention relates to a fireproof board. Background technique [0002] In order to reduce the indoor heat of the building from dissipating to the outside and ensure the indoor temperature, we usually cover the building with a layer of insulation board. The insulation board plays an important role in creating a suitable indoor thermal environment and saving energy in building insulation. [0003] The current thermal insulation boards generally can only be used for thermal insulation, and are generally poor in terms of fireproof performance, and if a fireproof board is used, the thermal insulation performance is poor. Although some current fireproof boards can achieve fire prevention and heat preservation, if fire protection is incorporated into heat preservation, it will inevitably lead to poor heat preservation effect, and the current fireproof heat preservation boards cannot realize fire extinguishing in the event of a fire, and cannot extinguish t...

[0003] The current thermal insulation boards generally can only be used for thermal insulation, and the fire performance is generally poor, and if the fireproof board is used, the thermal insulation performance is poor

Although some current fireproof boards can achieve fireproofing and heat preservation, if fireproofing is incorporated into heat preservation, it will inevitably lead to poor heat preservation effect, and the current fireproof heat preservation boards cannot realize fire extinguishing in the event of a fire, and cannot extinguish the flame in the budding state. It can only be used for fire prevention, and there are many deficiencies in use. How to ensure the heat preservation performance and realize fire prevention and fire extinguishing is the problem to be solved by the present invention.
