Description

A kind of foamed ceramic using industrial inorganic hazardous waste and fire clay mine tailing as raw material Warming plate and preparation method
Technical field
The invention belongs to building material field, particularly relates to one kind with industrial inorganic hazardous waste and fire clay tail Ore deposit is the exterior insulation and preparation method of raw material.
Background technology
Industrial dangerous waste refers to the caused hazardous waste in industrial enterprise's production process, is the danger according to national regulation Waste judging standard and discrimination method identification, there is the solid waste to environment or damaging property of human body.Industrial dangerous waste Bulk deposition do not occupy substantial amounts of land resource, while larger harm is brought to environment.Though industrial dangerous waste is Waste caused by industry but still have value, and if make full use of, can not only reduce the harm to environment, save work The disposal costs of industry hazardous waste environmental protection, while also create certain economic value.At present, part industrial dangerous waste Applied in ceramic industry and sintered building material, achieve the effect that industrial dangerous waste recycles.But industry danger Dangerous salvage value is very low, and most hazardous wastes use the conventional process such as chemical reaction, landfill, seal isolation at present, Treatment cost is high, efficiency is low, potential safety hazard is larger.
High temperature foamed ceramic warming plate be it is a kind of have heat-insulated and fire-proof function high-performance materials for wall concurrently, may replace building The air entrained concrete brick of interior wall and the foamed plastics of exterior wall, are with a wide range of applications.High temperature foamed ceramic is molten Under conditions of melting, foaming agent produces oxidation or reduction reaction, the gas discharged are wrapped in the inside of material by high-temperature fusant, drawn Play the overall expansion of material.Therefore, need to introduce a certain amount of fluxed raw material during high temperature foamed ceramic is prepared, rise To fluxing action.Such as " a kind of exterior insulation and preparation method thereof "(CN 102887721 A)Disclose with feldspar, cunning Stone, laterite, fluorite, lithium feldspar etc. are the method that fluxed raw material prepares exterior insulation.Patent of invention " hole foaming of holding one's breath The preparation method of ceramic thermal insulation plate "(CN 1026033557 A)Disclose a kind of foaming using waste glass powder as fluxed raw material Ceramic thermal insulation plate.It is matrix material that the above method, which employs ceramic polished brick slag, and natural material or general industry solid waste are to help Flux, the utilization to general industry solid waste have certain facilitation, but do not consider application of the dangerous solid waste in the field.
Calcium fluoride sludge caused by photovoltaic enterprise, red mud caused by nonferrous smelting, white clay and paper pulp caused by pulp manufacture Green mud is formulated into industrial dangerous waste caused by manufacture.These hazardous wastes are the materials using inorganic matter as Main Ingredients and Appearance Potassium oxide, sodium oxide molybdena, iron oxide, calcium oxide, magnesia in material etc. can play a part of fluxing agent.Meanwhile calcirm-fluoride The elements such as the calcium carbonate in the iron oxide in calcirm-fluoride, red mud, white clay and green mud in sludge are preferable high-temperature foaming agents, Enhanced foaming can be played a part of.Therefore, these industrial inorganic hazardous wastes can be with the process for preparing high temperature foamed ceramic Efficiently utilized.
The content of the invention
The object of the invention is exactly to be provided a kind of dangerous with industrial inorganic for the weak point in the presence of prior art Waste and exterior insulation and preparation method that fire clay mine tailing is raw material.
The purpose of the present invention can be realized by following technique measures:
The exterior insulation of the present invention includes the raw material of following weight percentage:Wherein fire clay mine tailing 55~ 75wt%, industrial inorganic hazardous waste 10~30 wt %, 5~15wt% of natural quartz, the wt % of high-temperature foaming agent 0.5~5.
Heretofore described fire clay mine tailing is derived from alumine, flint clay, kaolinite, andalusite, kyanite, silicon The combination of any one or two kinds and the above in line stone or mild-clay mine tailing;Described industrial inorganic hazardous waste is derived from light Calcium fluoride sludge caused by volt or glass processing enterprise, red mud caused by nonferrous smelting, white clay or paper pulp caused by pulp manufacture The combination of any one or two kinds and the above in green mud caused by manufacture;Described high-temperature foaming agent is derived from SiC, Fe2O3, carbon Powder, CaSO4, any one or two kinds in dolomite or lime stone and the above combination.
The preparation method step of the present invention is as follows:
A, fire clay mine tailing, industrial inorganic hazardous waste, natural quartz, high-temperature foaming agent are taken by weight percentage, according to weight Amount ratio mix, add water and mill ball, roller mill in fine grinding obtain within 1~8 hour mix pug, mud material granularity≤0.044mm;
B, by mixing pug prepared by step a through being dehydrated, be granulated, be molded, dry after, be sent into tunnel cave or roller kilns, Calcined 1~3 hour under the conditions of 1100~1300 DEG C, obtain high temperature foamed ceramic;
C, exterior insulation is obtained after the cleaved working process of high temperature foamed ceramic prepared step b.
Present invention employs wet method fine grinding technology, and the uneven low-grade alumina-silica ore deposit of Impurity Distribution and industrial hazard are given up Thing handles to obtain the equally distributed high temperature foamed ceramic of component by processes such as fine grinding, shaping, calcinings, avoids mine tailing and danger The phenomenon of accumulation of impurities in waste, resulting high temperature foamed ceramic product quality is stable, excellent performance;Prepared foaming pottery The compressive resistance of porcelain warming plate is between 2.0~8.0MPa, and bulk density is in 0.3~0.8g/cm3Between, it is a kind of high-performance Insulation walling.
Beneficial effects of the present invention are as follows:
The present invention using industrial inorganic hazardous waste difficult to deal with and the low-down fire clay mine tailing of utilization rate as primary raw material, The environmental protection utilization of industrial dangerous waste can be played, the utilization rate of resource of tailings is improved, reduces the multiple beneficials such as production cost effect Fruit.Industrial inorganic hazardous waste can reduce the eutectic point of fire clay mine tailing, play a part of fluxing agent, while calcirm-fluoride is dirty The calcium carbonate in the iron oxide in calcirm-fluoride, red mud, white clay and green mud in mud plays the effect of enhanced foaming at high temperature.
