Description

A kind of environmental protection brick
Technical field
The present invention relates to field of environment protection, be specifically related to a kind of environmental protection brick.
Background technology
Brick body is the material of construction closely bound up with people, and traditional brick body take clay as main raw material.But along with the development of society especially building trade, progressively increase the demand of brick, if use clay simply will certainly cause a large amount of breaking-up of ploughing as raw material, this state basic policy of preserving the ecological environment with China is beyond doubt contrary.Therefore, research and develop and a kind ofly use that other raw materials replace clay, the environmental protection brick with superior performance becomes urgent problem.
Summary of the invention
The present invention is by the raw material composition of adjustment brick body, employ Kaolin Tailings powder, colliery powder, zeolite powder and andaluzite etc. as main raw material on the one hand, with the addition of the compositions such as nano aluminium oxide, nano magnesia, nano titanium oxide simultaneously, both achieved environmental protection, in turn ensure that brick body had good performance.
Be specifically related to a kind of environmental protection brick, it is characterized in that its raw material is composed as follows by weight: Kaolin Tailings powder 20-30 part, colliery powder 20-30 part, zeolite powder 10-20 powder, andaluzite powder 10-15 part, nano aluminium oxide 3-5 part, nano magnesia 2-4 part, nano titanium oxide 5-7 part, silicon powder 6-8 part, zirconia powder 5-8 part, silicon nitride powder 5-10 part, Graphite Powder 99 3-5 part, carborundum powder 5-8 part, yttrium oxide powder 3-5 part, chromium oxide powder 2-5 part, Stainless Steel Fibre 3-5 part.
Environmental protection brick preparation technology of the present invention is easy: raw materials weighing according to the rules, carries out ball-milling processing after mixing; Add suitable quantity of water after ball milling, obtain slip; By slip shaping forming; Carry out drying subsequently and fire process.
The present invention has following advantage and effect:
1, have employed Kaolin Tailings powder, colliery powder, zeolite powder and andaluzite etc. as main raw material, raw material sources are extensive, especially for use Kaolin Tailings powder and colliery powder, achieve the recycling for waste.
2, by adding the raw materials such as nano aluminium oxide, nano magnesia, nano titanium oxide and silicon powder, by its content of reasonable disposition, improve the reactive behavior between raw material, the consumption of the low activity raw materials such as Kaolin Tailings powder, colliery powder in raw material can be improved on the one hand thus, brick body can also be made under lower firing temperature to obtain the characteristics such as higher intensity, and time prepared by brick body of the present invention, sintering temperature only needs less than 1000 DEG C simultaneously.
3, by adding the raw materials such as zirconia powder, silicon nitride powder, Graphite Powder 99, carborundum powder, by its content of reasonable disposition, improve the characteristics such as the wear resistance of brick body, heat-shock resistance.
4, by the suitable selection proportioning of all kinds of raw material type and content, environmental protection brick of the present invention can reach following performance index: normal temperature strength >=240MPa, thermal shock resistance (1100 DEG C of water-cooleds) >=10 times, apparent porosity≤10%, Mohs' hardness >=8.
