Refractory plate

Abstract

The invention relates to the technical field of building materials, and discloses a refractory plate. The refractory plate comprises an upper layer plate, a middle layer plate and a lower layer plate; the bottom of the upper layer plate is connected to the top of the middle layer plate, and the bottom of the middle plate and the top of the lower layer plate are connected; the top of the upper layer plate is opened with circular grooves, the upper layer plate where the circular grooves are located in is opened with first radiating grooves, and the side surfaces of the upper layer plate are opened with second radiating grooves which are communicated with the first radiating grooves; and the middle layer plate comprises a calcium oxide layer, an alumina silicate layer, a refractory clay layer, a perfluoroether rubber layer, a silicon monoxide layer, a corundum layer, a magnesium oxide layer, and a bonding layer. The calcium oxide layer, the alumina silicate layer, the perfluoroether rubber layer, the silicon monoxide layer, and the magnesium oxide layer are arranged for the refractory cement plate, so that the cement plate has good and high efficient fire resisting effects; the circular grooves, the first radiating grooves and the second radiating grooves are arranged, so that the refractory has good thermal discharge and heat radiating effects, when the refractory plate is subjected to fire hazard.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fire-resistant board. Background technique [0002] Cement board is a common building material. It is easy to construct, energy-saving and environmentally friendly. It has been widely promoted and used in the construction industry. In order to meet the fire protection needs of specific buildings, fire-resistant boards are usually installed during the construction of such buildings. [0003] The fire resistance of the existing fire-resistant water is poor, and only a few through holes are simply opened to achieve the effect of fire resistance and fire prevention. However, this cannot solve the non-fire resistance of the fire-resistant board very well, making it easy for the fire-resistant board to be exposed to fire. The danger of fracture and burnout occurs, which affects the normal use of road surfaces and walls, thereby reducing the practicability of fire-resistant...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a fire-resistant board, which has the advantages of good fire resistance, enhanced practicability of the cement board, and protection of people's lives, etc. There will be problems of fracture and burnout and the practicability of cement boards will be reduced
