Description
Technical field
The present invention relates to a kind of building and ornament materials, be specifically related to a kind of iron tailings powder environment-friendly type artificial stone and production method thereof.
Background technology
Iron tailings, be exactly former iron ore crush, sieve, grind, classification, again through selecting process such as gravity treatment, flotation or cyanidings, select the remainder after the metals such as useful ferrum, namely Ore remaining solid waste after sorting out concentrate, be the key component of industrial solid wastes.
The discharge capacity of China's iron tailings is big and makes a low multiple use, and stores up land occupation, even can pollute surrounding enviroment.Adding up according to " Chinese environmental statistical yearbook 2009 ", it is 2.24 hundred million tons that whole nation ferrous metal ore selecting and purchasing industry produces industrial solid castoff amount for 2008, and its comprehensive utilization ratio is only 25.1%, and the comprehensive utilization ratio of mine tailing only has 7%.From 1949～2009, whole nation iron tailings discharge capacity substantially 6,200,000,000 tons, and it also with the speed increment of annual 1.1 hundred million tons.The landfill of storing up in a large number of iron tailings not only needs to take a large amount of soil, consumption manpower, material resources and financial resources are managed, and groundwater resources, surrounding enviroment can be played serious impact by the airborne dust etc. caused containing the harmful substances such as heavy metal and thin tailings particles in part iron tailings.
The mine tailing of domestic main iron ore mine is similar with external iron tailings chemical composition, mainly: SiO2、Al2O3、Fe2O3, CaO and MgO, the content of chemical composition is along with there being larger difference from different places.Its mineralogical composition mainly quartz, bloodstone, calcite, dolomite, Anhydrite etc., similar to the mineralogical composition of natural sand, can be considered the mineral materials such as a kind of silicate of " being combined ", carbonate, be a kind of potential secondary resource.
But the utilization to iron tailings is still in the elementary step in terms of artificial stone, and it is big generally to there is formula for a product difference, the drawbacks such as constant product quality difference, so the necessary formula reasonability to iron tailings artificial stone, constant product quality aspect are more studied, to meet the market demand, also the secondary for iron tailings utilizes and provides a kind of new method and approach.
(the Hou Yanyan such as Hou Yanyan, Lee is thick. and utilize iron tailings to prepare cloudier diamond stone experimental study [J]. mineral products comprehensively utilize, 2011,05:37-40.) with unsaturated-resin, iron tailings as primary raw material, casting at normal temperatures and pressures is prepared for cloudier diamond stone plate, and have studied the impact on properties of product of the varigrained iron tailings.Cloud diamond stone plate tensile strength and comprcssive strength that the method prepares are low, and service life is shorter.CN201410776011.9 discloses a kind of exceptional hardness artificial quartz stone plate and manufacture method thereof, this artificial quartz stone plate is calcined quartzs 30～80 parts by 6～100 mesh, 325 mesh silica flours 30～60 parts, cullet 5～10 parts, fiber 5～10 parts, unsaturated unsaturated-resin 5～10 parts, auxiliary agent 0.3～0.5 part, pigment 0.3～0.8 part, above-mentioned each component is uniformly mixed, by evenly laid out for the material that mixes on making sheet mould, then making sheet mould is sent into moulding press in vacuum, vibration, add pressure to be shaped, it is re-fed into curing oven solidification, i.e. prepare artificial quartz stone plate.This material primary raw material is the quartz after high-temperature calcination, needs through pretreatment, and cost of material is high.CN201310271381.2 discloses a kind of high-strength composite Inorganic artificial stone and preparation method thereof, this artificial stone consists of aggregate 30～65%, cement 25～60%, composite modifier 1～10%, water reducer 1～5%, retarder 0～1.5%, water 8～20%, the size of described aggregate presses the weight grating of aggregate.By in the aggregate of predetermined weight size grating, cement, composite modifier, water reducer time addition blender and uniform stirring, the water adding approrpiate wts carries out uniform stirring again, cloth and compacting under vacuum conditions, wet foster solidification, cuts, polishes and get product.The composite inorganic artificial stone color that the method prepares is single, it is difficult to meet the demand of market diversification.CN201420809827.2 discloses a kind of waste stone dust composite artificial stone, its structure is followed successively by inorganic artificial rock layers, the artificial rock layers of high-load waste stone dust unsaturated-resin, the artificial rock layers of low content waste stone dust unsaturated-resin and unsaturated-resin antimicrobial surface from top to bottom, the surface distributed of described inorganic artificial rock layers irregular zigzag groove, in the described high-load artificial rock layers of waste stone dust unsaturated-resin, the mass percent of waste stone dust is more than the described low content artificial rock layers of waste stone dust unsaturated-resin, and described each layer uses graded composite preparation technology to be processed into an entirety.The composite artificial stone of the method gained has a risk of cracking, and complex process, it is not easy to operation.A kind of composite stone material and preparation method thereof disclosed in CN200610124077.5, consisting of Binder Materials 35～45%, inserts 55～65%, additive 1～5% and appropriate pigment；The production method of this composite stone material include dispensing, mixing, cloth, heat, the demoulding, maintenance, cutting, airing, repairing, strike-through, the step such as fine grinding process.This composite stone material utilizes organic pigment to colour, the most ageing-resistant, easily fades.
