Abstract
The invention relates to a method for producing light-weight inorganic plates by using industrial waste slag, mainly solving the problem of harm of waste materials to the environments discharged by porcelain production enterprises mainly producing polishing bricks and simultaneously overcoming the defects that the traditional external wall material has poor performance in heat insulation, corrosion resistance, fire prevention, weathering resistance and the like. According to the method, the light-weight inorganic plates are produced by using industrial waste slag as the main material and the components of silicate, borate, industrial calcium carbonate, industrial sodium carbonate or borax as the auxiliary materials; and the method comprises the steps of drying the industrial waste slag, mixing the waste slag with a fluxing agent and a foaming stabilizer, then ball milling and screening, putting the mixture into a mold, putting the mold into a kiln for burning; and the industrial waste slag in the steps is one or a plurality of waste porcelain, waste polishing slag, converter slag and iron tailings. The plates can replace the existing outer wall heat insulation materials, is low in cost and constructed conveniently, and has good durability; the influence of natural disasters such as fire and earthquake on buildings and the personal safety as well as the property safety is effectively reduced; and by utilizing the method, the waste material resources such as polishing waste slag are fully utilized, the resource utilization of solid wastes is improved, and the method can be widely applied to the field of building materials.
Description
Technical field
The present invention relates to a kind of method of utilizing industrial residue to prepare light body inorganic plate, belong to material of construction manufacturing and applied technical field.
Background technology
In recent ten years, the architectural pottery industry of China obtains fast development, and the existing building Ceramics Enterprises surpasses 3500, and the annual production of architectural pottery product accounts for the No. 1 in the world more than 3,000,000,000 square metres.Account for half of architectural pottery product as the polished tile output of China's characteristic ceramic product, in the abrasive polishing process process that polished tile is produced, can produce a large amount of solid slags (in siccative, every production 1m
2Polished tile namely produces about useless powder 2kg), be called ceramic polished waste residue (ceramic polishing waste, CPW).According to investigations, annual polished tile manufacturing enterprise, has increased the weight of to a great extent the burden of enterprise and has affected the production schedule of enterprise up to millions of even up to ten million units for the expense of processing polishing slag.Although at present the comprehensive utilization for polishing slag compares many research, but still lack it is carried out the correlation technique of extensive recycling, therefore its processing is main mainly with landfill, environment has been caused have a strong impact on.The polishing slag air storage also can to environment, be unfavorable for Sustainable development.Known polishing slag utilizes technology less, mainly utilizes polishing slag to prepare light heat insulation material.But, in existing correlation technique prepared lagging material exist unit weight general large, ultimate compression strength is lower, the heat-insulating properties of goods still need the series of problems such as further raising.At present, China's building exterior wall heat preserving material therefor is mainly with organic materialss such as benzene plate, polyurethane foam materials, and the inorganic materials such as rock cotton board, glass wool.Wherein, the benzene plate is the most cheap, but its heat insulation effect is general, can absorb water in use procedure, the problem such as distortion, finish measures such as also need doing corresponding waterproof after thermal insulation layer; The heat-insulating property of polyurethane foam material will be higher than the benzene plate, and especially the thermal conductivity of polyurethane foam material is far below the benzene plate, but the price of polyurethane foam material will be apparently higher than the benzene plate.In addition, the organic materialss such as benzene plate, urethane in use have thermotolerance and loss of properties on aging and easy firing.Can discharge the shortcomings such as amount of heat, generation poison gas, acceleration fire spreading during burning.The inorganic heat insulation material such as rock cotton board, glass wool not only polluted air but also easy breed bacteria easily work the mischief to health of human body.
Summary of the invention
The objective of the invention is for above-mentioned the deficiencies in the prior art, and a kind of method of utilizing industrial residue to prepare light body inorganic plate is provided.The method is mainly take polishing slag as raw material, solved well polished tile and be main Production of Ceramics enterprise wastage to the harm problem of environment.The shortcomings such as traditional outer wall material insulation, corrosion-resistant, fire prevention and weather resistance be poor have also been overcome simultaneously.
For achieving the above object, the present invention adopts following technical proposals: a kind of method of utilizing industrial residue to prepare light body inorganic plate, the method utilizes industrial residue as main raw material, be aided with silicate, borate, technical calcium carbonate, industrial sodium carbonate or borax component, prepare light body inorganic plate.Its preparation method is realized by following processing step:
(1) industrial residue is carried out drying treatment at 90～110 ℃.
(2) polishing slag and suds-stabilizing agent, the fusing assistant that obtain in step (1) are pressed quality %, wherein polishing slag, fusing assistant, suds-stabilizing agent are with 85～90: 5～10: 1～5 ratio is mixed, afterwards mixture is packed into and carry out in ball grinder crossing 200 mesh sieves after dry ball milling is processed, get the lower part of screen and divide.Above-mentioned fusing assistant adopts one or more in glass powder, sodium phosphate or borax, and suds-stabilizing agent adopts one or more in technical calcium carbonate, industrial sodium carbonate and silicon carbide, and the volume ratio of ball-milling medium ball and material is 1: 2～3.
(3) material that makes in step (2) is put into the mould that combines, the mould box shape that is square, material is the cordierite-mullite material.
(4) mould and the material to be burnt that arrange in step (3) are put into kiln, burn till by following technological process:
First be warming up to 1180～1250 ℃ from room temperature with the rate of heating of 5～10 ℃/min, insulation 30～60min; Then with the speed of cooling fast cooling to 1000 of 15～20 ℃/min ℃, insulation 20～40min; At last, namely get light body inorganic materials after being cooled to room temperature with the speed of 3～5 ℃/min.
(5) use making external-wall heat-insulation material after the light body inorganic materials cutting that makes in step (4), finishing.
Industrial residue in above-mentioned steps (1) is one or more in useless porcelain, polishing slag, converter slag, iron tailings.
The present invention has solved preferably take polished tile as main Production of Ceramics enterprise wastage the harm problem of environment and the existing unit weight that utilizes industrial residue to prepare to exist in light body inorganic materials technology is large, ultimate compression strength is lower, the series of technical such as heat-insulating property of goods.The light body inorganic materials unit weight that adopts present method to make is little, corrosion-resistant, high temperature resistant, ultimate compression strength is high, excellent thermal insulation performance, fire resistance are good.Can farthest reduce because of the fire Probability in skin heat preservation construction and transformation process, effective guarantee people life property safety.Can substitute existing external-wall heat-insulation material and use, have very high security, take full advantage of the waste material resources such as polishing slag, improve the recycling of solid waste, have good economic worth and the value of environmental protection.
