In one case, the first and second coatings 701, 703 may include: the slurry and the whole fiber cloth are sequentially laid in layers;
in another case, the first coating layer 701 and the second coating layer 703 may include: short fiber cloth and slurry, wherein the short fiber cloth and the slurry are mixed to form the first coating layer 701 and the second coating layer 703.
It should be noted that when the surface of the wall panel has different color requirements, the first coating layer 701 may further include: a gear line; the stop line is disposed on the first sub-layer of the first coating layer 701 to divide the bottom surface of the wallboard mold into a plurality of regions according to the color requirement.
If the first cover layer 701 is laid in the manner described above in the first aspect, the first sub-layer may be of the same or different colour in different regions and the third and subsequent sub-layers may be of a conventional colour slurry.
If the first cover layer 701 is laid in the second way, the color of the first sub-layer in different areas is the same or different, the thickness of the first sub-layer is the same as the height of the stop line, and the sprayed sand on the first sub-layer is the sprayed sand with the conventional color.
The height of the stop line is small, generally about 1-2mm, and the stop line is equivalent to a reinforcing rib in the wallboard, so that the strength of the wallboard can not be reduced, and the strength of the wallboard can also be enhanced.
The spraying sand is a mixture of short fiber cloth, slurry and color paint, and the short fiber cloth is broken fiber cloth.
The fiber cloth can be carbon fiber, glass fiber or nylon fiber and the like; the fiber cloth can be coarse fiber cloth or fine fiber cloth, the specification of the fine fiber cloth is 5 x 5, namely 5 warps are arranged in 1cm, and the coarse fiber cloth is 5-mesh interwoven fabric.
The slurry may be FLC, gypsum, concrete or cement, and the like.
According to the technical scheme, the building wallboard produced by the process is simple and convenient in production process and short in production time, and various required patterns can be produced at one time when the wallboard is produced.
According to the detection of an authority department, when the slurry of the wallboard is FLC, the fiber cloth is glass fiber, and the coating layer is paved by adopting the first mode, the detection result of the wallboard with the specification of 1220, 2440 and 15mm is that the compressive strength of the wallboard is 90MPa and is far larger than or equal to 50MPa specified by the state, the bending strength of the wallboard is 25.5MPa under the dry condition, and the bending strength of the wallboard is 38.1MPa under the water saturation condition and is far larger than or equal to 7MPa specified by the state.
Furthermore, the formaldehyde emission of the wallboard is 0.1mg/L and is far less than or equal to 1.5mg/L specified by the state through the detection of an authoritative department. The external irradiation index and the internal irradiation index of the wallboard are far better than the standard values specified by the state.
Therefore, the process method for producing the building wallboard, provided by the embodiment of the invention, is simple and convenient in process and short in production time, can be used for producing various required patterns at one time while producing the wallboard, and the produced wallboard is far higher in overall strength than national standard strength, non-toxic and environment-friendly, so that the production cost is relatively low.
Moreover, because the filler is wrapped in the middle of the first covering layer and the second covering layer, the wallboard further has the advantages of being good in heat insulation, sound insulation, fireproof, waterproof, tasteless, free of freezing, corrosion, cracking, changing, non-combustible, long in service life and the like.
In addition, the area of one wall plate is almost equal to the area of one wall of a house to be built or the area of a roof of the house, so that the using area of the building is increased in practical application, and the building has good earthquake resistance. And, because only the dismouting of monoblock wallboard when building the house, therefore it can used repeatedly, promptly when having demolishd the house that the wallboard built that uses the embodiment of this application provided, can use to demolish the wallboard and build required house again in other places, therefore further reduced the material cost and the time cost of building the house. Because the weight of the building wallboard produced by the method provided by the embodiment of the application is only one tenth of that of the traditional wallboard, the wallboard produced by the production process provided by the embodiment of the application also has the characteristics of high strength and light weight.
Through relevant experiments, the wallboard provided by the embodiment of the application can be used for easily building buildings with less than four floors without other steel frames and the like, and is firm and reliable.
