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

Abstract

The invention discloses a high-performance fireproof plate and a preparation method thereof, and belongs to the technical field of fireproof materials. The high-performance fireproof plate sequentially comprises a plate core, fireproof plate bodies and veneers from inside to outside, and the plate core is composed of a skeleton and a filler, wherein the skeleton is filled with the filler. The filler comprises the components of, by weight, 100-500 parts of perlite, 100-200 parts of oil sludge ash, 50-150 parts of tobermorite, 30-50 parts of sodium silicate, 10-20 parts of magnesium oxychlorideand 500-1000 parts of water, wherein the oil sludge ash comprises the components of, by weight, 50-150 parts of shale brick ash, 20-40 parts of kaolin, 30-50 parts of straw ash, 10-20 parts of slakedlime, 10-30 parts of tung oil, 30-50 parts of starch glue and 100-200 parts of water. Meanwhile, preparation of the fireproof plate comprises the three steps of skeleton preparation, plate core filling and finished product pressing and forming. The synthesized attribute of the fireproof plate can be better improved through the synergetic promotion effect of the multiple kinds of fire-resistant materials, the multilayered structure of the fireproof plate is pressed and formed through pressure, the structure is compact, and the airtightness is good.

Description

technical field [0001] The invention relates to a high-performance fireproof plate 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 fr...
