Abstract
The invention relates to a method for making a building material by low-temperature ceramic modified industrial side product gypsum, belonging to the building material technical field. The compositions adopted by the method are mixed according to the following mass ratio that: gelating material: side product gypsum: filler: activator: auxiliary agent: water reducing agent: polymer emulsion: solvent is equal to 100:300-900:50-500:80-150:12-30:1.0-10:0-50:50-500. The raw materials respectively undergoes raw material treatments such as gelating material powder preparation, waste gypsum treatment, filler crushing screening and polymer emulsion-solvent mixing and so on, and then are made into a building material which takes low-temperature ceramic mineral generated by the hydration of an inorganic waste residue gelating material as matrix phase and waste residue particle, waste gypsum and a hydration product thereof as disperse phase through the mixing, forming and maintenance working operation of a semi-finished product raw material. The building material has excellent mechanical property, high comprehensive utilization rate of wastes, more derivative products and stable performance.
Description
One, technical field:
The present invention relates to a kind of method for producing building material with low-temperature ceramic modified industry by-product gypsum, belong to the material of construction preparing technical field.
Two, background technology:
So-called industry by-product gypsum be industry production processes dischargings such as chemical industry, metallurgy, the energy, food be the byproduct of main component with the terra alba, as desulfurized gesso of flue gas, phosphogypsum, titanium gypsum, fluorgypsum, citric acid gypsum, wet method manganese slag and the plumbous cadmia etc. of coal-burning power plant's by-product.Output is big on the one hand for these industry by-product gypsums, land occupation, more main is wherein also to contain human body and the deleterious material of environment such as free acid and heavy metal ion, and its safe handling and recycling have become the great environmental problem that relevant industries need to be resolved hurrily.Form and character different based on industry by-product gypsum and the plaster of paris, people have adopted a lot of technological methods that waste gypsum is handled, hope at building material industry and can replace plaster of paris utilization, product relates to cement setting retarder, building gypsum plaster, wall body brick, hollow lath and Thistle board, in these technology, related waste gypsum is handled gordian technique two aspects:
The one, waste gypsum at first obtains semi-hydrated gypsum through washing, dry, calcined dehydration, is the basic material subsequent product of deriving then with the semi-hydrated gypsum, and more representative patent documentation has CN200610042205.1, CN200610100929.7, CN200610070220.7, CN200710092850.9, CN03108111.8, CN200610043618.1, CN02138799.0, CN02138088.0, CN200710066191.1, CN02110236.8, CN200710024752.1, CN200610050960.4.Some has realized suitability for industrialized production these technology, as: Ningxia GSFC of western Shandong chemical industry group adopts " dodge burning method phosphogypsum and produce building gypsum plaster " technology to build up domestic article one and produced 200000 tons of phosphogypsum building material made production lines per year; The rapid-result building of Australia RBS company limited has succeeded in developing gypsum roasting technology and equipment and has produced hollow big plate complete set technology, equipment with calcined gypsum; The big powder company in east, Liaoning has succeeded in developing " producing semi-hydrated gypsum for building with phosphogypsum " technology.
The 2nd, generally all to adopt washing, drying, calcined dehydration method to exist energy consumption height, water consumption to cause new environmental pollution problems greatly, in addition at the waste gypsum in the above-mentioned technology, add chemical assistant and other industrial residue waste gypsum is carried out modification, the manufacturing material of construction of deriving then, adopt the representative patents document of this technical scheme to have: CN200510126627.2, CN97107330.9, CN200510032313.6, CN200510020444.2, CN200510040512.1, CN00109901.9, CN200710075766.6, CN200710053782.5.Representative paper has: low-temp ceramics phosphogypsum base composite gelled material research (Kunming University of Science and Technology's journal, the super qin of sun, Xia Jupei, Zhang Zhao states .2007.8, vol.32 (4): P66-68), the preparation of phosphogypsum base composite gelled material (Yunnan chemical. Xia Jupei, the super qin of sun, Su Yi .2005.2, vol.32 (1): P21-23).From above-mentioned document as can be seen, technologies such as waste gypsum does not wash with water, drying, calcining, and by adding lime, cement, the plaster of Paris and the industrial residue such as the non-burning brick known technology that become of productions such as slag, flyash not activated but that have lateral reactivity of specified proportion; In order to improve product performance, vitriol, silicate, phosphoric acid salt, borate, villaumite and the organic waterproof agent of adding alkali and alkaline-earth metal in batching have become known technology; For the formability of improving goods with give the product property, in batching, add sandstone, pearlstone, some waste particle and be similarly known technology.
Industrial residue prepares that the low-temp ceramics matrix material is existing to be reported: as Chinese patent literature disclosed 200610010688.7,200510010946.7,200710137584.7,03135919.1,200810058211.5 etc.The something in common of above-mentioned low-temp ceramics matrix material is: the matrix of matrix material be mutually with industrial residue be main raw material through behind the grinding under cooperating based on the activator of alkali or properties-correcting agent, pass through steam heating, the original silicate sturcture of waste residue powder is dissociated, and reorganization aggregates into new silicate minerals, difference be in: the wild phase of matrix material or disperse phase are respectively plant residuum, plastic waste, undisturbed industry waste residue, macromolecular material and pore.The involved industrial residue as low-temp ceramics gelling material main raw material is yellow phosphorus slag, Metal smelting slag, chemical waste gypsum relieving haperacidity slag, flyash, calcining mine tailing, calcining coal gangue, calcining red mud in these patent documentations, and does not relate to undressed industrial waste gypsum; The involved disperse phase industrial residue as the low-temp ceramics matrix material of these patent documentations is municipal refuse incineration slag, sludge incineration slag, coal-fired slag, yellow phosphorus slag, Metal smelting slag, metallurgy and cast waste sand, waste concrete, barren rock, does not also relate to undressed industrial waste gypsum.
Comprehensive existing document is not difficult to find out, is that the low-temp ceramics gelling material that main raw material prepares comes the building materials utilization of solidification treatment waste gypsum and then realization waste gypsum not see bibliographical information as yet with industrial residue.
Three, summary of the invention:
