Abstract
The invention discloses a cordierite ceramic which comprises 60-80 parts of kaolin, 1.8-3.2 parts of clay, 18-25 parts of talcum, 4-7 parts of magnesium carbonate, 9-14 parts of paraffin and 0.1-0.5 part of oleic acid. By adopting the special raw material formula instead of the raw materials dependent on import, the cordierite ceramic disclosed by the invention has the advantages of low price, excellent comprehensive properties, heat resistance, wear resistance, corrosion resistance, electric insulation and the like. The manufacturing process disclosed by the invention is simple and easy to implement.
Description
Technical field
The present invention relates to the stupalith field, relate in particular to a kind of cordierite ceramic and preparation method thereof.
Background technology
at present, the heat resisting porcelain of domestic production main raw material used is to rely on the Australian triphane that produces of import, add the triphane matter heat resisting porcelain blank that high grade kaolinite becomes with the material combination such as quartzy, the consumption of triphane in the heat resisting porcelain blank formulation is up to 45%～50%, this raw material is most of to be produced for domestic lithium ingot, according to lithium content height in triphane, its price volalility is at 2700 yuan～3200 yuan/tons, annual with 30%～50% rise price import in recent years, and starting material are rare, supply falls short of demand, often cause heat resisting porcelain producer to hold up work for lack of material, therefore the heat resisting porcelain localization of raw material is the problem of domestic each enterprise and the research of ceramic R﹠D institution always, but existing research cost is unsatisfactory.
In addition, the cordierite ceramic of excellent combination property is people's demand always, so become necessary to the research of cordierite ceramica material.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, and technical problem to be solved is to provide the cordierite ceramic of a kind of heat-resisting, wear-resisting, protection against corrosion, insulation.
The technical problem that the present invention also will solve is to provide the preparation method of above-mentioned cordierite ceramic.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of cordierite ceramic, it comprises the component of following parts by weight:
Wherein, preferably, a kind of cordierite ceramic, it comprises the component of following parts by weight:
The preparation method of above-mentioned cordierite ceramic, it comprises the steps:
1, press formula ratio, get carry out ball milling, batch mixing after kaolin, clay, talcum, magnesiumcarbonate batching, to be crushed to 300～400 orders standby;
2, paraffin, the oleic acid with formula ratio is heated to 110～130 ℃ to fusing, crosses 150 mesh sieves;
3, raw material standby in step 1 is anhydrated, paraffin and the oleic acid that sieves in step 2 is added in standby raw material, mix rear employing injection moulding at 0.5MP, 60～70 ℃ of condition compacted unders;
4, burn till 1000～1100 ℃ of de-waxings, 1200～1300 ℃ and get product.
Beneficial effect: cordierite ceramic of the present invention, adopt special composition of raw materials, replace the starting material of dependence on import, not only cheap, and excellent combination property, have the performances such as heat-resisting, wear-resisting, protection against corrosion and insulation.Manufacturing process of the present invention is simple, is easy to realize.
