The carbide slag brick prepared by the invention has the characteristics of large carbide slag mixing amount, high strength, excellent heat resistance and water resistance, smooth surface, stable physical properties and the like. The raw materials are widely available, the production process is simple, no energy consumption is caused, and no pollution is caused, so that the waste is a typical environment-friendly and energy-saving product which changes waste into valuable.
Description
Technical field
The present invention relates to a kind of high-strength non-evaporating non-sintering carbide residue brick of exempting to press, relate in particular to a kind of catalytic gluing carbide slag brick, belong to building and ornament materials.
Background technology
Carbide slag is that the waste residue that produces after the calcium carbide hydrolysis is only produced the 1tPVC resin and will be produced butt carbide slag 1.4~1.8t in industrial production acetylene (raw materials of Chemicals such as polyvinyl chloride, the polyvinyl alcohol) process.The carbide slag that China's industrial production produces surpasses 5,000,000 tons/year, and utilization ratio is less than 10%.Because carbide slag quantity is big, transportation cost is higher, the carbide slag that present domestic chemical industry manufacturer produces is most of to be adopted and stacks on the spot or the mode of landfill is handled.So not only taken valuable land resources, and air, surface water and underground water have also been produced bigger influence.
At present, the relevant patent of carbide slag brickmaking is less, disclosed patent as: publication number is the non-fired and non-steamed bricks that the CN1093688A patent is introduced, be to be major ingredient with a certain proportion of flyash, slag, carbide slag, it is evenly mixed to add curing hardening accelerator, by brick pressing machine compression moulding under 43.5MPa pressure, becoming flyash through maintenance again is main brick.The carbide slag utilization is less, is no more than 20%, requires to have flyash, slag, three kinds of industrial wastes of carbide slag simultaneously, and it is higher to collect the transportation raw materials cost.Publication number is that the high pressure no-baking carbide residue brick of CN1673151A patent introduction is that warp 〉=40MPa is high, and pressing die forms after mixing with sandstone, carbide slag, solid phase binder, liquid phase binding agent and water.Its carbide slag utilization increases, but needs its liquid phase binding agent of high temperature power consumption preparation, also needs to add certain organism and high-pressure molding, and curing time is long maybe need to add the dry ice maintenance, and cost is higher.The Miniature hollow building block with calcium carbide dregs concrete that publication number is introduced for the CN1087695 patent, be characterized in based on concrete, with the compound instead of part cement of carbide slag and flyash, carbide slag utilization ratio<10%, curing cycle while is long, is generally 28 days.The carbide residue brick carbide slag volume of the present invention's preparation is big, utilization ratio 25-75%, intensity height, 7 days ultimate compression strength>10MPa.
Summary of the invention
The objective of the invention is to have proposed a kind of no energy consumption, pollution-free, the glued non-evaporating non-sintering carbide residue brick of exempting to press of environment protection catalytic, the instead of clay brick in order to improve the more high deficiency of prior art cost.
Technical solution of the present invention is: with the carbide slag is main raw material, and a certain proportion of inorganic fine aggregate that mixes adds an amount of water, is prepared from a kind of high-strength non-evaporating non-sintering carbide residue brick of exempting to press by inorganic catalytic activator gluing.
Concrete technical scheme of the present invention is: a kind of catalytic gluing carbide slag brick is characterized in that the weight percent that its raw material each component and each component account for the raw material total amount is: the inorganic catalytic activator 15-25% of the inorganic fine aggregate 0-50% of carbide slag 25-75%.
Wherein, inorganic catalytic activator is the mixture of active metal oxide and metal-salt, and its weight percent that each is formed and respectively composition accounts for the stimulator total amount is respectively SiO

2SiF
6(0.05-0.1%) and CeO
2(0.01-0.03%).Inorganic catalytic activator of the present invention can be prepared at normal temperatures.
Described inorganic fine aggregate is at least any one in quartz sand, stone chippings, glass cullet, concrete particle in small, broken bits or the fiber aggregate in small, broken bits, and granularity requirements is crossed 16 mesh standard sieves.
The present invention also provides the preparation method of above-mentioned carbide residue brick, its concrete steps are: after earlier the ball mill pulverizing of calcium carbide clinker being sieved, take by weighing calcium carbide ground-slag, inorganic fine aggregate and inorganic catalytic activator by the above-mentioned raw materials prescription, after stirrer mixes, add entry, behind the restir batch mixing, mold forming natural curing is gone in charging, obtains required carbide residue brick.
Wherein the calcium carbide clinker needs ball mill pulverizing to cross 40 mesh standard sieves.The part by weight of the add-on of water and raw material siccative is controlled at (0.3-0.6) among the above-mentioned preparation method: 4, and amount of water can be adjusted in right amount according to the humidity of material.
Beneficial effect:
Carbide residue brick of the present invention is compared with existing carbide residue brick, and because of using the catalyzing activation jelling agent, the carbide slag utilization ratio improves greatly, the ultimate compression strength height and the stable physical property of brick, smooth surface, water-fast fine heat-resisting performance, raw material is concentrated and is easy to get, can gather materials on the spot and found the factory, need not expend the transportation raw material.Simultaneously, production process does not have energy consumption, and production technique is simple, need not high-pressure molding, and cost is low.
