Embodiment 1

[0042] The magnesium phosphate gel suspension is composed of dead-burned magnesium oxide powder, potassium dihydrogen phosphate, calcined vermiculite powder, fly ash and borax retarder; the mass ratio of magnesium oxide powder and potassium dihydrogen phosphate is 3:1, and the calcined Vermiculite powder and fly ash accounted for 10% of the total gel, respectively, and borax retarder accounted for 6% of the magnesium oxide powder. The magnesium phosphate gel is mixed with water according to the stated proportion to form a magnesium phosphate cementitious slurry, which is cured to form a magnesium phosphate cementitious material; the thickness of the magnesium phosphate adhesive layer between the silica aerogel sheet and the heat-resistant foam concrete 0.5cm; the fireproof sealing material of the composite laminate and the cable are sealed with a fireproof caulking material; the fireproof caulking material in the fireproof sealing of the composite laminate is a mixture of magne...

Abstract

The invention discloses a cable channel composite material laminated plate fireproof partition and a construction method thereof. The fireproof partition comprises a composite material laminated plate fireproof wall, a composite material laminated plate fireproof plug, a cable hole and a structure boundary, the composite material laminated plate fireproof plug is arranged in the center of the composite material laminated plate fireproof wall, and the cable hole is formed in the composite material laminated plate fireproof plug. A structure boundary is arranged on the periphery of the composite material laminated plate firewall, and the composite material laminated plate firewall is composed of a magnesium phosphate cementing material surface layer and a heat-resistant foam concrete layer. The composite material laminated plate fireproof plug is formed by sequentially laminating a magnesium phosphate cementing material surface layer, a silicon dioxide aerogel thin plate and a heat-resistant foam concrete layer. The fireproof partition is excellent in heat resistance and fire resistance, convenient to construct and non-toxic.

Description

technical field [0001] The present invention relates to the fire protection technology of cable channel, in particular to a fire partition of composite material laminated board of cable channel and its construction method. [0002] technical background [0003] Because the cable channel structure is buried underground, the spread of fire will cause the equipment in the structure to burn and cause huge economic losses. Therefore, the requirements for its fire resistance and fire resistance are extremely high. At present, the fireproof board of this kind of channel structure is mainly made of magnesium oxychloride cement and glass fiber composite bonding. This kind of fireproof board has certain fire resistance, but it has low strength, poor fireproof and heat insulation effect, and the strength decreases greatly after high temperature. And the disadvantage of high thermal conductivity. However, the existing fire-stopping bags and organic mud used in the plugging and partition...
