A kind of fireproof board and preparation method thereof

Abstract

The invention discloses a fireproof plate and a preparation method thereof, and belongs to the technical field of fireproof materials. The fireproof plate comprises a plate core, a fireproof plate body and a veneer from inside to outside sequentially, wherein the plate core comprises frameworks and filler filled between the frameworks; the filler is prepared from components in parts by weight as follows: 200-600 parts of perlite, 150-300 parts of a calcium carbide substrate, 35-45 parts of sodium silicate, 8-16 parts of magnesium oxychloride and 600-1000 parts of water; the calcium carbide substrate is prepared from components in parts by weight: 60-160 parts of CaO, 50-150 parts of kaolinite, 20-30 parts of mullite fiber, 3-5 parts of Fe2O3, 10-20 parts of polyvinyl alcohol, 30-50 parts of dolomite fiber and 600-800 parts of water. Meanwhile, the fireproof plate is prepared by the following three steps: preparation of the frameworks, filling of the plate core, and pressing of a finished product. By means of the synergistic effect of various refractory materials, the comprehensive property of the fireproof plate can be better enhanced. The multi-layer structure of the fireproof plate is pressed by pressure, so that the structure is compact, and the seal property is good.

Description

technical field [0001] The invention relates to a fireproof board and a preparation method thereof, belonging to the field of fireproof materials. Background technique [0002] Fireproof materials refer to various materials that play an absolute role in modern fire prevention and are mostly used in buildings, including fireproof boards, fireproof boards, etc. Fireproof materials have the property of preventing or retarding the spread of flames, and there are usually two types of non-combustible materials and difficult-to-combustible materials. Noncombustible materials do not burn. Although flame-retardant materials can be burned, they are flame-retardant, that is, they are difficult to catch fire and carbonize, and they can stop burning after the fire source is removed. [0003] Since humans know and use fire, fire has become an inseparable part of our life and production. Whether it is a natural forest fire or a fire caused by electricity, fires occur frequently in our l...

Problems solved by technology

However, the alloy of the traditional fireproof board itself has low fire resistance, and the filling is difficult to continuously resist the burning of the flame, and the fireproof effect is not good.

[0005] Aiming at the disadvantages of low fire resistance and passive fire protection of traditional fireproof boards, Publication No. 104929499A discloses a material box with additional dry powder installed so that dry powder can be used for active fire extinguishing in case of fire

However, in a real fire scene, the effect of relying on the dry powder attached to the fireproof board is negligible, and it is difficult to provide time for escape
