Description

A kind of environmental protection brick
Technical field
The present invention relates to field of environment protection, and in particular to a kind of environmental protection brick.
Background technology
Brick body is the construction material closely bound up with people, and traditional brick body is using clay as primary raw material.But with society Can especially building trade development, the demand of brick is incrementally increased, if simply use clay will certainly as raw material Cause the breaking-up largely ploughed, this is undoubtedly what is disagreed with the state basic policy that China preserves the ecological environment.Therefore, research and development are a kind of uses Other raw materials replace clay, the environmental protection brick with superior performance to become urgent problem.
The content of the invention
The present invention forms by adjusting the raw material of brick body, has on the one hand used Kaolin Tailings powder, bastard coal mountain flour, zeolite powder Primary raw material is used as with andalusite etc., while with the addition of the components such as nano aluminium oxide, nano magnesia, nano-titanium dioxide, both Environmental protection is realized, in turn ensure that brick body has preferable performance characteristics.
More particularly to a kind of environmental protection brick, it is characterised in that its raw material composition by weight is as follows:Kaolin Tailings powder 20-30 Part, 20-30 parts of bastard coal mountain flour, zeolite powder 10-20 powder, 10-15 parts of andalusite powder, 3-5 parts of nano aluminium oxide, nano magnesia 2- 4 parts, 5-7 parts of nano-titanium dioxide, 6-8 parts of silicon powder, 5-8 parts of zirconia powder, 5-10 parts of silicon nitride powder, 3-5 parts of graphite powder, carbon 5-8 parts of SiClx powder, 3-5 parts of yttrium powder of oxidation, 2-5 parts of chromium oxide powder, 3-5 parts of stainless steel fibre.
Environmental protection process for producing bricks of the invention is easy:Raw material is weighed according to the rules, and ball-milling treatment is carried out after mixing;Add after ball milling Enter suitable quantity of water, obtain slurry;By slurry shaping forming;Then it is dried and firing is handled.
The present invention has the advantage that and effect:
1st, Kaolin Tailings powder, bastard coal mountain flour, zeolite powder and andalusite etc. are employed and is used as primary raw material, raw material sources are wide It is general, particularly with Kaolin Tailings powder and bastard coal mountain flour is used, realize the recycling for discarded object.
2nd, by adding the raw materials such as nano aluminium oxide, nano magnesia, nano-titanium dioxide and silicon powder, by rationally matching somebody with somebody Its standby content, improves the reactivity between raw material, thus on the one hand can improve Kaolin Tailings powder in raw material, bastard coal mountain flour Deng the dosage of low activity raw material, while brick body can also be made to obtain the characteristics such as higher intensity under relatively low firing temperature, this Sintering temperature only needs less than 1000 DEG C when prepared by invention brick body.
3rd, by adding the raw materials such as zirconia powder, silicon nitride powder, graphite powder, carborundum powder, by its content of reasonable disposition, Improve the characteristics such as wearability, the thermal shock resistance of brick body.
4th, following performance can be reached by all kinds of raw material types and the appropriately selected proportioning of content, environmental protection brick of the invention Index:Normal temperature strength >=240MPa, thermal shock resistance (1100 DEG C of water coolings) >=10 times, apparent porosity≤10%, Mohs' hardness >= 8。
