Description
The present invention relates to a kind of preparing process of high strength fibre plain gypsum board, belong to architectural decoration gypsum sheet material production method class.
Since plastering both had light weight, fire prevention, sound insulation, heat insulation, regulate in the building numerous optimum functions such as humidity, have again good can ornamental and processability; So be applied in the building finishing more and more widely.
Thistle board is the most representative gypsum decorative plate over nearly more than 20 years, is widely used in interior decoration in the world decorates with material.But, also manifest its unsurmountable defective in the practical application: because the mask paper that the intensity of Thistle board mainly is close on the face of being affixed on plays the skeleton supporting role to gypsum plank, for to guarantee that gypsum plank has the enough gas permeabilities and the performance of humidity conditioning function, what its mask paper was mainly used is wood fibre paper simultaneously; And the present domestic demand that can't satisfy Thistle board to mask paper, as seen to mask paper require extraordinaryly, this is an one.Its two, the intensity of Thistle board is limited, especially is unwell to wet environment and uses; Separate otherwise can come unstuck with gypsum core, have a strong impact on the intensity of Thistle board because of the facial tissue of Thistle board.Its three, plastering is natural superfine fire proofing material, and the Thistle board fire-protection rating only is the B level.
In recent years, for the applicability that further improves gypsum sheet material, the intensity that strengthens sheet material, reducing the short fiber that its dependence to mask paper proposed to mix with dispersed is the fibrous plaster of reinforcing agent.Because fibrous plaster has more advantage than Thistle board, has especially overcome the defective of Thistle board on intensity; So the new solution around fibrous plaster increased with day at present.
But because the material formula difference that various technical scheme adopts, the manufacture craft difference is so its mechanical property is also each has something to recommend him.Especially at the breaking load of sheet material, the amount of deflection of making moist aspect is also not ideal.According to studies show that: the intensity of gypsum plank mainly also depends on the incorporation of water in the gypsum except depending on the aggregate and enhancing material that mixes wherein.Gypsum, as a kind of air-setting cementing agent, can not lack of water, can not many water.Giving full play to the ventilative humidity conditioning function of plastering generally speaking, the suitable water yield of gypsum is about 75% of a plaster of Paris consumption, and its water supply volume can reduce to 63～53% under the participating in of water-reducing and set-retarding admixture.
Purpose of the present invention: be to provide a kind of material proportion of new high-strength fibrous gypsum plate and the breaking load that production method wishes further to improve gypseous decorating board, the amount of deflection of making moist, reduce the breaking load drop-out value after making moist, not only simplify production technology but also reduce production costs simultaneously.
Dominant ideas of the present invention are: the selection by the combination material improves, and further reduces the consumption of water under the participating in of Admixture, improves the physical property of sheet material.
The present invention is achieved through the following channels:
This high strength fibre plain gypsum board is made up of plaster of Paris, inorganic hydrophilic waterproof powder, expanded perlite, staple glass fibre, multi-functional plasticizing and water, the mix proportion scheme of its composition is to mix 5～50 parts of inorganic hydrophilic waterproof powder in per 100 parts of plaster of Paris, mix 0.5～3 part of expanded perlite, mix 1～4 part of staple glass fibre, mix 2～10 parts of multi-functional fluidizers, 32～84 parts of water mixings.
Described inorganic hydrophilic waterproof powder is formed its slag powders: silicate powder by slag powders and hydroxide or silicate powder: hydroxide=10: 3: 0.3～1.5.
Described multi-functional fluidizer is mixed the suitable quantity of water solution composition by a kind of in the pure and mild alum of Lauxite modified poly ethylene, borax, silicic acid, carbon ammonium or several; And in modified polyvinylalcohol: alum: the ratio combination of water=10: 1～3: 10.
Described high strength fibre flat board is equipped with 1～2 layer of fiberglass gridding cloth in plate body.
The manufacture craft of described high strength fibre plain gypsum board is: siccative stirring → wet feed stirs → falls slurry and goes into mould → vibration and pave → extrusion modling → demoulding maintenance → go into kiln drying.
Further set forth the present invention below in conjunction with embodiment:
Embodiment 1, (in hundred parts of ratios of weight)
5 parts of 100 parts of inorganic hydrophilic waterproof powder of plaster of Paris
1 part of 0.5 part of staple glass fibre of expanded perlite
58 parts in 2 parts of water of multi-functional fluidizer
Embodiment 2, (by weight percentage)
20 parts of 100 parts of inorganic hydrophilic waterproof powder of plaster of Paris
2 parts of 2 parts of staple glass fibres of expanded perlite
50 parts in 5 parts of water of multi-functional fluidizer
Embodiment 3, (by weight percentage)
50 parts of 100 parts of inorganic hydrophilic waterproof powder of plaster of Paris
4 parts of 3 parts of staple glass fibres of expanded perlite
47 parts in 10 parts of water of multi-functional fluidizer
Embodiment 4, (by weight percentage)
50 parts of 100 parts of inorganic hydrophilic waterproof powder of land plaster
4 parts of 3 parts of staple glass fibres of expanded perlite
84 parts in 10 parts of water of multi-functional fluidizer
Described inorganic hydrophilic waterproof powder is made up of slag powders and hydroxide powder or silicate powder, and described multi-functional fluidizer adds water by a kind of in the pure and mild alum of Lauxite modified polyethylene or borax, silicic acid, carbon ammonium or several and combines.
The concrete manufacturing process of this high strength gypsum fiberboard is: at first with siccative plaster of Paris, the inorganic hydrophilic waterproof powder of required component, expanded perlite carries out mixing of siccative; Then add short glass fiber, multi-functional fluidizer and water and carry out the wet feed stirring; To pour in the making sheet mould through the slurry that stirs subsequently, it should be noted that must be at template die bottom layer overlay fiberglass gridding cloth before falling to starch; And then vibrate and pave, slurry is paved in template die, lay the layer of glass grid cloth simultaneously in the above in addition; When laying the upper strata fiberglass gridding cloth, by pressure roller the slurry that paves in template die is pushed simultaneously, make it reach certain compactness: to treat then to enter the demoulding maintenance stage after sheet material solidifies substantially, and finally after going into kiln drying, check warehouse-in.
High strength fibre plain gypsum board according to the technique scheme making, its breaking load 500N above (10mm heavy-gauge sheeting), amount of deflection≤the 1.2mm that makes moist has not only remedied the defective of Thistle board, also is better than common known fiber gypsum plank on some performance indications.
This high strength fibre stone that the present invention introduces is high dull and stereotyped, so only can have stronger physical property, except lay 1～2 layer of fiberglass gridding cloth in plate body, also has benefited from its combination matching; Especially the inorganic hydrophilic waterproof powder and the multi-functional fluidizer that adopt in filling a prescription.The inorganic hydrophilic waterproof powder that the present invention adopts is to be served as by slag powders and hydroxide or silicate powder, and these two groups of combinations of materials all are the materials with latent hydraulicity.When they and plaster of Paris, water are admixed together, generate calcium silicates, be filled in the hole of plastering inside, reduced the degree of porosity in the plate body with hydraulicity.Simultaneously, also just because of having adopted inorganic hydrophilic waterproof powder and multi-functional fluidizer, because inorganic hydrophilic waterproof powder constituent is at its extremely strong hydrophilicity of mixing initial stage, add diminishing, plasticising, the slow setting function of multi-functional fluidizer, make the dull and stereotyped overall watering quantity of the high-intensity fiber gypsum that adopts present technique to be controlled in 32～54%.Mix the later stage and have the water-repellent material such as calcium silicates of the hydraulicity, so have waterproof, moisture resistance function because mixture generates.Certainly, the raising of plate body intensity also has benefited from adopting the employing of extrusion forming process; Because this process using, make that also the plate body compactness is strengthened, hole in the gypsum plate body obtains reducing, can absorb an amount of water and participate in reconfiguring of material, simultaneously because above-mentioned numerous factors, institute is so that the high strength fibre plain gypsum board of application the technical program has good physical and mechanical property.
