Abstract

The invention provides a fireproof blocking plate. The fireproof blocking plate consists of a main material, a frame layer reinforcing material, a light material, a modifier and water, wherein the main material consists of magnesium chloride and magnesium oxide; the frame layer reinforcing material consists of glass fibers; the light material consists of vermiculite and perlite; the modifier consists of hydrochloric acid. The fireproof blocking plate has the advantages of being manufactured by scientifically mixing and pressing a plurality of incombustible materials; the fireproof blocking plate has the fire resistance and the characteristics of long incombustible time in fire, high mechanical strength, strong explosion resistance, water resistance, oil resistance, chemical corrosion resistance, non-toxicity and the like; meanwhile, the fireproof blocking plate does not deform when the highest temperature of the flame reaches 1000 DEG C in a combustion test of inorganic fire barriers; all the indexes of the fireproof blocking plate meet the specified requirements of GB23864-2009; the combustion property can reach the standard of grade A (incombustible) in the regulations of GB8624.

Description

technical field [0001] The invention belongs to the field of fireproof materials, in particular to a fireproof blocking board. Background technique [0002] In the field of construction, no matter it is the fire-proof and flame-retardant project of interior decoration, or the fire-proof and flame-retardant of cable engineering in cable-intensive places, it is inseparable from the fireproof board. The glass magnesium board is made of magnesium forming agent, glass fiber mesh cloth, filler, etc. As raw material, it is made by mechanical rolling, and is mainly used for indoor non-load-bearing walls and ceilings, as well as substrates for various decorative panels. The glass magnesium board in the prior art usually uses magnesium oxide and magnesium chloride as forming agents. In order to make the magnesium fully and quickly condense, the content of magnesium chloride should not be too low, otherwise the purpose of making the magnesium fully and quickly condense cannot be achiev...
