Fireproof cement product

Abstract

The invention relates to the technical field of building materials and discloses a fireproof cement product. The product comprises an upper-layer plate, a middle-layer plate and a lower-layer plate, the bottom of the upper-layer plate is connected with the top of the middle-layer plate, and the bottom of the middle-layer plate is connected with the top of the lower-layer plate; a circular groove is formed in the top of the upper-layer plate, a first heat dissipation groove is formed in the upper-layer plate where the circular groove is located, and a second heat dissipation groove communicatedwith the first heat dissipation groove is formed in the side face of the upper-layer plate; the middle-layer plate is composed of a calcium oxide layer, an aluminium silicate layer, a fire-resistantclay layer, a full-isoflurane rubber layer, a silicon oxide layer, a corundum layer, a magnesium oxide layer and a bonding layer. According to the fireproof cement plate, by arranging the calcium oxide layer, the aluminium silicate layer, the full-isoflurane rubber layer, the silicon oxide layer and the magnesium oxide layer, the cement plate can have a good and efficient fire-resistant effect; byforming the circular groove, the first heat dissipation groove and the second heat dissipation groove, the effect is achieved that the cement plate can better achieve heat discharge and heat dissipation work when the cement plate is subjected to a fire disaster.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fireproof cement product. 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, refractory cement boards are usually installed during the construction of such buildings. [0003] Existing refractory cement boards are poor in fire resistance, and only a few through holes are simply opened to achieve the effect of fire resistance and fire prevention. It is prone to the danger of fracture and burnout, which affects the normal use of road surfaces and walls, thereby reducing the practicability of cement boards and threatening people's lives. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies in the p...

AI Technical Summary

Problems solved by technology

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