Description
Technical field
The present invention relates to mineral resources comprehensive utilization technical field, it is especially a kind of using clay production Ceramic Tiles and its
Preparation method.
Background technology
Clay is a kind of mineral resources, and global content is compared with horn of plenty, and ore is predominantly purplish red, reddish brown thick massive is calcareous
Siltstone, contains siltpelite, clay rock at siltstone containing mud.According to correlation detection data, the clay in southwests such as Guizhou provides
Source amount is larger, and it is more than 80,000,000 tons just to have clay resource amount at this in Guizhou Yuqing, and thickness reaches 280m, can carry out
A large amount of strip mining transformation.But for the comprehensive utilization of clay resource, in the prior art there is also a large amount of insufficient,
Main cause is：A large amount of clay resource grade is low, tonerde component, its impurity content are more, so that it is in tradition
It is used only for the raw material of production clay tile and crude pottery product in technology, and then causes clay production value-added content of product relatively low,
Market prospects are poor, and then hinder the comprehensive utilization of clay resource so that a large amount of clay resource cannot get good utilization；
Also, when raw material for producing clay tile and crude pottery product, second-rate, the especially mechanical property of the product that obtains
It can be poor, it is difficult to meet architecture mechanical property requirements, so that the market prospects for a large amount of clay product made
By limitation.
There is researcher to show in clay, fundamental component be quartz, clay mineral, dolomite, calcite, plagioclase,
Microcline, Siliceous Fragments, mica sheet, bloodstone, limonite, glauconite, zircon, tourmaline and irony etc., and further
Obtain, in high calcium clay, the content of calcium oxide is 10-20%, and the content of di-iron trioxide is 2-10%.As it can be seen that in height
Calcium content and iron content in calcium clay is relatively high.
In the prior art, researcher prepares High-calcium ceramic using calcium class mineral calcite or stalactite, but due to side
It solves stone or stalactite volume is less and higher to the quality requirements of remaining dispensing；And then lead to the cost of the ceramic product made
Larger, clay dosage is relatively low, as patent publication No. is《CN103086697A》It is a kind of using calcium class mineral calcite or clock breast
The method of standby High-calcium ceramic made of stones；Also researcher prepares ceramics production with clay mixture using Boccaro shale as raw clay
Product, but since clay volume is less, and CaO and Fe2O3 contents are less than 1% in its clay；And then lead to the ceramics production made
The cost of product is larger, obtains the second-rate of product, is not easy to polish, and manufacture craft difficulty is larger, as patent publication No. is
《CN103833326A》A kind of method preparing ceramic product as raw clay using Boccaro shale and clay mixture.
As it can be seen that in the prior art, it is difficult to the product for widely applying acquisition best in quality in clay, it especially cannot be big
Amount applies low-grade clay raw material, and then causes clay resource production value-added content of product relatively low, and cost is higher, and then hinders
The comprehensive utilization of clay resource.
Invention content
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of ceramics produced using clay
Brick can produce the ornament materials with high-quality using low-grade clay as raw material, and the anti-folding and anti-pressing for obtaining product is strong
