Abstract

The invention discloses a red ceramic tile and a manufacturing method thereof. The ceramic tile is prepared from the following raw materials in parts by mass: 50-60 parts of red mud, 15-25 parts of kaolin, 15-25 parts of perlite, 10-15 parts of quartz sand, 5-10 parts of fly ash, 2-5 parts of andradite, 2-5 parts of gehlenite and 2-5 parts of diopside. The manufacturing technique comprises the following steps: material selection, powder preparation, compaction, drying, glazing and firing to obtain the finished product. The use proportion of the red mud is greater than one half of the total raw materials; and the consumption of the red mud is maximally increased, thereby relieving the abundant discharge of the red mud which has no place to arrange, changing wastes into valuable substances, utilizing the waste, lowering the production cost and reducing the environmental pollution. The red ceramic tile is corresponding to new product research, development and application in the whole ceramic brick industry around the environment-friendly problems of energy saving, emission reduction, waste slag utilization and the like.

Description

A kind of red tile and preparation method thereof
Technical field
The present invention relates to silicates arts, be specifically related to a kind of red tile and preparation method thereof.
Background technology
Red mud is sorrel, powder pureed strong basicity solid waste remaining after bauxite produces aluminum oxide, is requisite by product in aluminum oxide production process.General often production 1t aluminum oxide, can output red mud 1.0 ~ 1.8t.Along with the development of aluminum i ndustry, China's red mud quantity discharged is approximately 5,000,000 t, and in the trend increased year by year.Storing up of red mud not only takies a large amount of soil and farmland, and the stockyard of at substantial is built and maintenance cost, and the alkali in red mud to subsurface wastewater infiltration system, can cause groundwater pollution.In addition, the dust that the red mud dried is formed flies upward everywhere, and broken ring ecotope, causes severe contamination.The comprehensive regulation of red mud has become one of focus that people pay close attention to, and utilizing red mud to prepare material of construction is one of effective way consuming red mud on a large scale.
Along with socioeconomic development, the energy consumption problem of building receives much concern, and China's building energy consumption is 3 times of developed country, and building energy consumption accounted for 10% of energy total flow and rises to more than 30% from 1978.Chinese patent CN2012102953915, provide a kind of method utilizing red mud to produce architectural pottery, it is characterized in that, the Antique Imitation Tiles utilizing red mud to produce is made up of the raw material of following mass percent: diopside 10%; Laiyang soil 27%; Mengyin feldspar 15%; Laiwu feldspar 15%; Green coke 10%; Highly dense porcelain stone 8%; Red mud 15%; Add the useless base of above-mentioned quality of material summation 5% in addition again.After adding red mud aborning, the shortcoming of red mud can be made up by adjusting process formula, the raw material containing red mud is met produce ceramic tile and watt processing requirement, but the red mud that above-mentioned patent uses is only 15%, can't resolve the quantity discharged of existing red mud far away.
Therefore, market is needed a kind of material of construction that red mud is utilized in a large number badly.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of red tile and preparation method thereof, utilization that can be a large amount of to red mud.
For achieving the above object, technical scheme of the present invention is: a kind of red tile, the raw material of ceramic tile comprises red mud, kaolin, perlite, quartz sand, flyash, andradite, gehlenite, diopside, shared by each raw material, mass fraction is: red mud 50 ~ 60 parts, kaolin 15 ~ 25 parts, perlite 15 ~ 25 parts, quartz sand 10 ~ 15 parts, 5 ~ 10 parts, flyash, andradite 2 ~ 5 parts, gehlenite 2 ~ 5 parts, diopside 2 ~ 5 parts.
A making method for red tile, comprises the steps:
A, to select materials: starting material warehouse entry will mainly comprise sampling through inspection, buy cake tries the steps such as burning, physicals detection, chemical analysis;
The preparation of b, powder: comprise batching, the preparation of slip, spraying dry powder process, feed bin are old;
C, compression moulding;
D, drying;
E, glazing;
F, to fire;
G, finished product.
Beneficial effect of the present invention: (1) uses the red mud of discharge to be one of structured material, the features such as the ceramic tile produced has that slip resistance is large, and unit weight is little, hypotonic and low erosion; (2) perlite is as one of raw material, can change gelatinized into about there being the SiO2 of 2% during quartzy fine grinding, effectively can improve the mobility of grout material, and improving the dry tenacity of blank.At high temperature perlite accelerates base substrate porcelain with its high chemically reactive again, strengthen and quartz particles is melted, be conducive to the densification of base substrate, not only effectively reduce the deformation defect of large part goods in burning till, the more important thing is the melt temperature 100 ~ 200 DEG C that can reduce base substrate, and widen the firing range of base substrate; (3) perlite is widely distributed in China, and verify existing 18 provinces at present and have perlite ore deposit, geological survey reserves reach more than ten hundred million t, its comparatively stable chemical composition and unique physicochemical property, alternative part kaolin and feldspar, and perlite is cheap, exploitation is convenient.The usage ratio of red mud is greater than 1/2nd of raw material sum, increases the usage quantity of red mud to greatest extent, discharges in a large number at alleviation red mud, while settling, can turn waste into wealth without ground, and utilization of waste material, reduces production cost, reduce the pollution to environment; Study around the product innovation of the environmental issue such as energy-saving and emission-reduction and waste residue utilization with whole ceramic tile industry, develop, apply and echo mutually.
Further, described red mud is Bayer process red mud, shows through a large amount of experimental datas, and Bayer process red mud is compared with red mud from sintering process, and firing range is large, and the improvement of firing property is best, and folding strength is higher.
Further, perlite is pearlstone, uses as mineral substance pore forming agent, reduces the oeverall quality more remarkable effect of finished product.
Further, flyash is obtain after ink-jet drying and stage of firing using coal dust firing, is the Appropriate application to resource, also reduces production cost simultaneously.
Further, raw material obtains the chemical constitution of raw material through chemical analysis test, first the chemical constitution of raw material is converted into the mineral composition of raw material, is carrying out charge calculation, through the calculating of science, is drawing optimal proportion.
Further, compression moulding is extrusion moulding, and extrusion moulding is polluted little.Be easy to automatization, feature that efficiency is high.
Further, firing temperature is 980 ~ 1080 DEG C, and at this temperature, finished product has indeformable, the feature such as flawless, not dry linting, and structure properties is more excellent.
