Description
Technical field
The invention belongs to building material field, relate in particular to a kind of calcareous vegetable fiberboard of magnesium and preparation forming method thereof that adopts organic materials and inorganic materials blended to have fire resistance.
Background technology
Along with the develop rapidly of Chinese society doctrine construction and improving constantly of living standards of the people, demand to timber increases substantially, therefore the felling quantity of log is increasing, makes original wood supply with regard to the few China of forest-covered area also become more nervous.In order to keep ecological balance and to satisfy building of the four modernizations and the growing needs of people, country is when strengthening imported timber quantity, more will greatly develop novel environmental-friendly construction material, save resource, the sharp useless substitute wood product of production are carried out energetically with long-term policy as an important behave and are advocated.Therefore, various fiberboards that utilize farm crop and other vegetable fibre productions and imitation wood thereof occur in succession and emerge in an endless stream, and its preparation method is also varied, though have his own strong points, weak point is arranged respectively also.Ubiquitous problem is: contain chemical additive such as UF or PF glue in the raw material mostly as binding agent, objectionable impurities wherein is contaminate environment but also the health that endangers the people not only; Most components are organism in the raw material, waterproof, fire prevention, anticorrosion, mothproof poor performance.Be head it off, Chinese patent application numbers 200710010019.4 discloses " a kind of ecological inorganic composite architectural materials ", adopting magnesium oxide, gypsum, high-alumina cement is the inorganic material that coagulates, add agricultural crop straw vegetable fibre and three wastes inorganic wastes, naphthalene series water reducer NNO, MF4, wooden calcium sulfonate, emulsifying agent, permeate agent and stirred solution magnesium chloride, sal epsom through aqueous fusion and, heated and boiled, enduring, condensation form.Its waterproof, fire prevention, anticorrosion, mothproof better performances, but yield rate and intensity are lower, and production rate is slower; Especially it is many to add organic materials properties-correcting agent and solution, and the problem of the anti-halogen of its finished fiber plate does not solve as yet at all.
Chinese patent application numbers 98106819.7 provides " a kind of making method of rice straw fibreboard ", adopts straw, alkaline hydrogen sodium hydroxide solution, acid H
2SO
4Solution, Resin adhesive and magnesium oxide are raw material, and it is stifling that straw is soaked, dewaters, adds alkali, high temperature; Dry, add acid, flushing; Batch mixing, stirring, oven dry; Series of process processes such as extravagance, high temperature oil pressure, cooling and cutting are made fire prevention, humidity resistance is good, the rice straw fibreboard that acid-fast alkali-proof intensity is high.Its technology slightly complicated, and need twice pyroprocessing, cost improves, and the fiberboard of particularly making still exists the defective of anti-halogen.
Summary of the invention
Purpose of the present invention is exactly in order to solve the problem of above-mentioned existence, aim to provide and a kind ofly substitute timber with organic the combination with inorganic substance, produce a kind of have better fire prevention, waterproof, anticorrosion, mothproof performance, and do not contain formaldehyde, radiationless, the intensity height, indeformable, vegetable fiberboard of anti-halogen and preparation method thereof not.
Technical solution of the present invention is:

0.025～0.03 part of sodium methyl silicate;
1.4～1.8 parts of stirred solutions, wherein: 0.75～1 part of magnesium chloride solution, 0.65～0.8 part in water.
Described magnesium cement is high-silicon low-calcium, activated magnesia should be between 62% ± 2, and its every composition weight forms and parameter is: MgO 80～86%, active CaO 1.0～1.5%, SiO
23.5～4.5%, Al
2O
32.2～2.9%, Fe
3O
41.0～2.0%; Loss on ignition is 3～11%.
The preparation method of magnesium calcium pyrophyte fiberboard of the present invention is to adopt half-dried material hot-forming, and its technological process comprises raw material preparation, batch mixing stirring, paving prefabricating, thermocompression forming and five contents of scale cutting.
The concrete operations step is:
1, raw material is prepared: one or more plant materials are put into pulverizer pulverize, make its powdering or staple length be not more than the powder of 10mm; In the described components by weight percent scope of claim 2, be ready to various raw materials by required proportioning weighing.
2, batch mixing stirs: earlier ready magnesium cement is mixed back adding magnesium chloride solution with aluminosulfate cement and stir; Simultaneously anhydrous plaster powder being added water stirs; After two kinds of pasty state material mixing and stirring that will stir again, add vegetable fibre and sodium methyl silicate successively, fully stir and form half-dried material.
3, paving prefabricating: the half-dried material that will stir is mated formation and carry out pre-molding to preformer, and precompression is 0.6～0.8MPa, and how much that mats formation and expect determines according to the thickness of goods.
4, thermocompression forming: the slab of pre-molding is put into multi-daylight press carry out the heating and pressurizing typing, plus-pressure is 2～4MPa, and Heating temperature is 65～85 ℃, and the heating and pressurizing time is 8～12min.
