Description
Technical field
The present invention relates to lagging material preparing technical field, particularly relate to preparation method of a kind of light foam lagging material and products thereof.
Background technology
Red mud produces the solid waste produced in alumina process, often produces one ton of aluminum oxide, approximately produces red mud 0.8-1.5 tons.China is alumina producing big country, nearly 3,000 ten thousand tons of the red mud produced for 2009, and China's red mud comprehensive utilization ratio is only 4% at present.Red mud is stored up in a large number, both land occupation, and waste resource, easily causes environmental pollution and potential safety hazard again.Meanwhile, China's house enters the large-scaled construction period, and materials for wall accounts for material of construction 70%, and developing new body of wall energy-saving material is the steps necessary realizing sustainable economic development.Light foam ceramic material has the advantages such as the physical strength that void content is high, thermal conductivity is low, lightweight, high temperature resistant, corrosion-resistant and good, is a kind of desirable Building Fire Protection heat preserving and insulating material.The waste materials such as the red mud utilizing aluminium manufacturer to pile up and scrap glass prepare foam ceramic thermal insulation material, not only save energy, and reduce production cost, and turn waste into wealth, protection of the environment, meets the green circulatory strategy of sustainable development.
There is the record utilizing red mud to produce red mud brick in prior art, if publication number is CN102276219A Chinese invention patent application, utilize Bayer mud 35%-43%, active material 27%-35%, consolidating material 12-20%, ground granulated blast furnace slag 2-10% production steam pressure red mud brick.Chinese patent CN200910186283 adopts 5-15%wt kaolin, 1-5%wt wilkinite, 15-40%wt potassium albite, 30-60%wt lithium porcelain stone, 5-15%wt calcium carbonate, 5-15%wt zirconium silicate, 0-8%wt fluorite and fluorocarbon surfactant to be that light foam lagging material made by raw material.But at present, only use red mud, scrap glass and unslaked lime, plaster stone or calcium carbonate are produced light foam lagging material and have no announcement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method and the product that utilize discarded red mud and glass manufacture light foam lagging material.
For achieving the above object, the invention provides following technical scheme: comprise step:
(1) red mud is dried, ball mill pulverizing, discarded cleaning glass, oven dry ball milling powder are broken into scrap glass powder;
(2) by the red mud after pulverizing, glass powder, whipping agent in mass ratio for the proportioning of 40-50:35-40:10-15 mixes;
(3) put into ball mill wet-milling mixing after making compound, form mixing mud; Mixing mud is adopted press spray granulating and drying, temperature out controls at 90-120 DEG C, is loaded by obtained powder in foaming refractory-material dies;
(4) sent in process furnace by the foaming refractory-material dies that powder is housed and be heated to 1100-1160 DEG C, insulation 8-12 minute, then anneals, cooling, and cutting obtains cellular insulant.
The preparation method of light foam lagging material of the present invention, preferred value is red mud, glass powder, and the mass ratio of whipping agent is 50:40:10.
The preparation method of light foam lagging material of the present invention, wherein said whipping agent is Wingdale or desulfurated plaster or calcium carbonate, and wherein in Wingdale, CaCO3 content is greater than 95wt%, and in desulfurated plaster, the content of CaSO42H2 is greater than 90wt%.
The preparation method of light foam lagging material of the present invention, preferred value is that described CaCO3 accounts for total mixture 10-15wt%.
The preparation method of light foam lagging material of the present invention, preferred value is that described CaCO3 accounts for total mixture 15wt%, and glass powder accounts for total mixture 35wt%.
The preparation method of light foam lagging material of the present invention, described type of heating is laser heating.
The preparation method of light foam lagging material of the present invention, the ball mill grinding time is 5-8 minute fineness≤100 micron making glass powder.
According to the product that any one method above-mentioned prepares.
Preparation method's difference from prior art of light foam lagging material of the present invention is:
(1) the present invention is with industrial waste red mud and glass for raw material, not only economizes on resources, and reduces production cost, and protects environment, turn waste into wealth.
(2) preparation technology of the present invention is simple, can make large-sized light foam lagging material continuously.
(3) the light foam performance of heat protective material prepared by is excellent: proportion is 1.2-1.5g/cm3, and intensity is 5MPa, and thermal conductivity is that 0.061W/ (mK) all meets relevant criterion.
Therefore, it is high that the method applied in the present invention has utilization rate of solid waste, and production cost is low, the advantage of less energy intensive; It is light that prepared product has quality, physical strength is high, excellent heat insulating performance, not easily brittle, the characteristic of good stability, basic parameter is all better than relevant criterion, can be widely used in building energy-saving heat-insulating material and the outer field energy-saving heat preserving field of other high temperature services, in particular for manufacturing building brick, respond well.
