Embodiment 1

[0029] Use two 6m long (200×70×20×3) C-shaped steel and two 1.5m long (100×50×20×2.5) C-shaped steel to weld the steel frame of the steel skeleton, and weld two layers in it Steel mesh, and then welded 5 U-shaped steel as a steel truss, and put the formed steel skeleton in the mold. Blend and stir 210kg of rapid-hardening sulfoaluminate cement and 90kg of fly ash, then add 150kg of water, 6120ml of hydrogen peroxide, 760ml of triethanolamine and 0.76kg of calcium stearate and continue to stir evenly. The core plate is formed by injection molding in the mold of the skeleton, and after the core plate is solidified, a layer of fiber mesh cloth is laid on the surface of the core plate, and then a cement surface layer is formed on the outside of the fiber mesh cloth with self-leveling cement, that is, the light weight of the present invention is obtained. Quality insulation and fireproof composite board.

Embodiment 2

[0031] Two 2.5m long (100×50×20×2.5) C-shaped steels and two 2.5m long (100×50×20×2.5) C-shaped steels are used to weld the steel frame of the steel skeleton, and two A layer of steel mesh, and then welded 4 U-shaped steel as a steel truss, and put the formed steel skeleton in the mold. Blend and stir 120kg of fast-hardening sulfoaluminate cement and 80kg of fly ash, then add 110kg of water, 4250ml of hydrogen peroxide, 530ml of triethanolamine and 0.53kg of calcium stearate and continue to stir evenly. The core board is formed by injection molding in the mold of the skeleton. After solidification, a layer of fiber mesh cloth is laid on the surface of the core board, and then a cement surface layer is formed on the outside of the fiber mesh cloth with self-leveling cement, that is, the light-weight thermal insulation of the present invention is obtained. Fireproof composite panels.

Embodiment 3

[0033] Two 5m long (180×60×20×3) C-shaped steels and two 1.2m long (80×40×20×2.5) C-shaped steels are used to weld the steel frame of the steel skeleton, and two layers are welded in it Steel mesh, and then welded 3 U-shaped steel as a steel truss, and put the formed steel skeleton in the mold. Blend and stir 120kg of fast-hardening sulfoaluminate cement and 30kg of fly ash, then add 60kg of water, 3264ml of hydrogen peroxide, 410ml of triethanolamine and 0.41kg of calcium stearate and continue stirring evenly, and pour the obtained mixture into a steel container. The core board is formed by injection molding in the mold of the skeleton. After solidification, a layer of fiber mesh cloth is laid on the surface of the core board, and then a cement surface layer is formed on the outside of the fiber mesh cloth with self-leveling cement, that is, the light-weight thermal insulation of the present invention is obtained. Fireproof composite panels.

Abstract

The invention relates to a heat-preserving and fire-proof composite plate with light weight and a producing method thereof; specifically, the method comprises the following steps: integrally welding a steel side frame, a steel truss and two layers of steel wire nets into a steel framework, and placing the formed steel framework in a mould; blending and mixing quick-hardened sulfate aluminum cement and coal ash, adding water and a foaming agent, and adding admixture and continuously mixing uniformly if necessary; pouring the obtained mixture into the mould with the steel framework to form a core plate in an injection molding manner; after the core plate is solidified, paving a layer of fiber net cloth on the surface of the core plate, and forming a cement surface layer on the fiber net cloth to obtain the composite plate of the invention. The composite plate has the excellent performances of light weight, heat preservation, fire resistance, shock resistance, weight bearing and the like, and can be widely used as a roof plate, a net frame plate, a floor plate, and the like.

Description

technical field [0001] The invention relates to a building board, in particular to a lightweight thermal insulation and fireproof composite board. Background technique [0002] At present, the roof and floor slabs used in the construction industry are mainly divided into two types. One is polystyrene board and rock wool board, which have good thermal insulation effect and are light in weight, but they cannot meet the requirements of load bearing, fire prevention and earthquake resistance. The other is cement boards and cast-in-place boards, which have good load-bearing, fireproof, and earthquake-resistant properties, but are heavy in weight and do not have heat preservation. Flammable substances are easy to catch fire, bringing great harm to the lives and property of the people of the country, and the cost is relatively high. Therefore, it is desired to have a new type of board with excellent properties such as light body, heat preservation, fire prevention, earthquake resi...
