Abstract
A fibre-reinforced cement slab is made of cement, powdered coal ash, hemp fibre and methylcellulose (MC) through proportioning, stirring, adding water, stirring again, delivering material, screw feeding, screw delivering, vacuum extruding for shaping, computer controlled synchronous delivering and cutting, drawing, shaping, curing and cutting. Its advantages are light weight, high strength, incombustible, sound insulation, protecting environment, saving energy and low cost.
Description
The present invention is a kind of material of construction, particularly relates to a kind of fibre-reinforced cement slab and preparation method thereof.
Be accompanied by the develop rapidly of national economy, Increase of population and standard of living improve constantly, economic construction and capital construction scale are in rapid expansion, the land resources occupancy volume is big, force building to develop to high level, under these circumstances, requirement to the demand of material of construction and quality is also more and more higher, and the sheet material of the long usefulness of construction industry is by cement at present, ground silica, asbestos, methylcellulose gum (MC) is formed, because ground silica costs an arm and a leg, the asbestos influence is healthy, the processing of also need plastering of its metope causes original sheet material manufacturing cost height, waste land resources, shortcomings such as contaminate environment, particularly the manufacturing cost height can't be accepted people.
The purpose of this invention is to provide a kind of with the original ground silica of coal ash instead, substitute original asbestos with flaxen fiber, have lightweight, high-strength difficult combustion, anticorrosion, insulate against sound, preserve moisture, heat insulation, the plate face of being convenient to again construct is smooth, do not need to do again the powder ash, thereby can shorten the construction period greatly, save the fibre-reinforced cement slab of the energy, material, man-hour and fund.
Another object of the present invention provides a kind of preparation method of fibre-reinforced cement slab.
Fibre-reinforced cement slab of the present invention contains cement, flyash, flaxen fiber and methylcellulose gum (MC), and the parts by weight proportioning of wherein said composition is as follows:
Cement 50-70 part
Flyash 30-47 part
Flaxen fiber 2-5 part
Methylcellulose gum (MC) 0.3-0.5 part
Wherein, described flyash can substitute with zeolite powder, and the proportioning of its zeolite powder is identical with the proportioning of flyash.In addition, methylcellulose gum (MC) also available polyethylene alcohol substitutes, and the proportioning of its polyvinyl alcohol is 1-2 part.
The content of the described composition of fibre-reinforced cement slab of the present invention changes in its specialized range, and making as required can be greatly, fibre-reinforced cement slab that can be little, also can be made into hollow plate or solid sheet material.
Fibre-reinforced cement slab of the present invention has the advantages that unit weight is light, performance of keeping humidity is good; particularly it also have anticorrosion, insulate against sound, preserve moisture, heat insulation effect; be convenient to construction again; the plate face is smooth; need not do the high-quality performance of wet trade; owing to adopted flyash widely, reach the protection environment again, save the energy, the purpose that reduces cost.
The preparation method of fibre-reinforced cement slab of the present invention is: after selecting materials, in proportion with cement, flyash, flaxen fiber, methylcellulose gum (MC) mix, Hou Jiashui stirs, restir is even, and slip conveying → screw feeder → helical feed → extrusion under vacuum → computer control synchronous transport cutting → computer control sync pulling → lateral transfer shaping then → give hard maintenance → processing is cut.
Wherein, do to mix and adopt sealing to stir, water pollution-free, atmospheric pollution, residue contamination meet the requirement of country to the environmental protection aspect.
Natural curing or vapor cure are taked in described maintenance, and product does not have particular requirement to meteorological conditions.
The preparation method of this fibre-reinforced cement slab is scientific and reasonable, simple, cost is low, high efficiency.
Below in conjunction with embodiment the present invention is described further.Embodiment:
A kind of fibre-reinforced cement slab, it contains cement, flyash, flaxen fiber, methylcellulose gum (MC), and the parts by weight proportioning of described various compositions is as follows:
50 parts of cement
30 parts in flyash
2 parts in flaxen fiber
0.3 part of methylcellulose gum (MC)
During preparation, the Hou Jiashui that in proportion cement, flyash, flaxen fiber, methylcellulose gum (MC) stirred earlier, restir evenly after through slip carry-→ screw feeder-→ helical feed-→ extrusion under vacuum-→ cutting of computer control synchronous transport-→ traction of computer control synchronous transport-→ the lateral transfer shaping-→ natural curing-→ the processing cutting gets final product.
