Glazed hollow bead fire retardant board and fire retardant heat insulation structure

Abstract

The invention relates to a glazed hollow bead fire retardant board and a fire retardant heat insulation structure. The glazed hollow bead fire retardant board takes glazed hollow beads as main raw materials and is formed in the mode that the glazed hollow beads are bonded together by using binder, and the volume percentage of the glazed hollow beads reaches 85 vol% or above. The glazed hollow bead fire retardant board and the fire retardant heat insulation structure do not need additives such as mortar and cement, also have the advantages that the glazed hollow bead fire retardant board and the fire retardant heat insulation structure are low in density, convenient to transport and short in production processing period, the fire retardant layer reaches 5 centimeters and accords with the fire protection rule, the production processing period is short, the water-proof layer, the heat insulation layer and the fire retardant layer are bonded firmly and cannot fall off, the bending strength is high, the compressive strength is high, and the glazed hollow bead fire retardant board and the fire retardant heat insulation structure are resistant to high temperature, belongs to fireproof grade A, and is higher in incombustibility and good in heat insulation performance.

Description

technical field [0001] The invention relates to a building material and a building structure, in particular to a vitrified microbead fire retardant board and a fire retardant and heat preservation structure. Background technique [0002] At present, in the technology of using vitrified microbeads to make the fireproof layer of external walls, vitrified microbeads are mixed in mortar to make a vitrified bead mortar layer to make the fireproof layer or fireproof insulation layer of the external wall. The bead mortar layer needs additives such as mortar and cement, and needs to be dried, dried, and requires special maintenance; specifically, this kind of vitrified microbead mortar layer has a high density and is inconvenient to carry during construction; and it is used as an external wall fireproof layer The thickness does not meet the fire protection requirements; 7 to 15 days of maintenance are required after production and processing, and the production and processing cycle ...

[0002] At present, in the technology of using vitrified microbeads to make the fireproof layer of external walls, vitrified microbeads are mixed in mortar to make a vitrified bead mortar layer to make the fireproof layer or fireproof insulation layer of the external wall. The bead mortar layer needs additives such as mortar and cement, and needs to be dried, dried, and requires special maintenance; specifically, this kind of vitrified microbead mortar layer has a high density and is inconvenient to carry during construction; and it is used as an external wall fireproof layer The thickness does not meet the fire protection requirements; 7-15 days of maintenance are required after production and processing, and the production and processing cycle is long; the insulation layer and the fire protection layer are not firmly bonded and easy to fall off

In addition to the above technologies, there are also expanded vitrified beads as lightweight aggregates, phenolic resin or emulsified asphalt or polyacrylonitrile as a binder to form a fireproof insulation layer through mold molding and sintering. This fireproof insulation layer needs to be compared with 100 parts of expanded vitrified glass is 50-200 parts of binder, resulting in limited content of expanded vitrified glass in the thermal insulation layer, and also requires a sintering process
