Background technology
Attapulgite clay, except containing attapulgite, often contains the mineral such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate.
With the volcanoclastic rock that also has of attapulgite clay ore deposit symbiosis, volcanoclastic rock is mostly on the upper strata in attapulgite clay ore deposit, the volcanoclastic rock ore bed on upper strata, some attapulgite clays mining area
'sthickness is up to tens of rice, at attapulgite clay in recovery process, the volcanoclastic rock on upper strata, attapulgite clay mining area is abandoned as waste, investigates factually, 1 ton of attapulgite clay of every exploitation, the volcanoclastic rock produced has more than 30 tons, by the output of producing 150000 tons per year, calculate, the volcanoclastic rock of generation, up to 4,500,000 tons, all can be utilized for many years, whole mining area is the volcanoclastic rock mixture of again piling up everywhere, causes the serious wasting of resources and financial loss.
Building waste refers to the waste that construction, unit in charge of construction or individual are built, lay or remove, produce in the repairerment process all kinds of buildingss, structures, pipe network etc.The composition of building waste has: the tr of the yellow ground be scattered in the mortar be scattered and concrete, brickbat and broken concrete, handling process, stone, piece stone, dregs, steel scrap muscle, waste iron wire, various steel scrap accessory, metal pipe line waste material, useless bamboo wood, wood chip, wood shavings, various finishing material and packing bag etc.
Summary of the invention
The objective of the invention is to overcome weak point in prior art, a kind of unburned Attapulgite building waste insulating brick is provided.
Unburned Attapulgite building waste insulating brick is by attapulgite clay mine tailing, building waste, volcanoclastic rock mixture, montmorillonite mine tailing, diatomite mine tailing and cement composition.
The production method of unburned Attapulgite building waste insulating brick: the batching of unburned Attapulgite building waste insulating brick process is stirred, be pressed into difform unburned Attapulgite building waste insulating brick work in-process, maintenance is carried out in conventional maintenance process according to cement products, is packaged as the finished product of unburned Attapulgite building waste insulating brick after 28 days.
Attapulgite clay can mix in recovery process a certain amount of rubble and earth, as a kind of mine tailing, abandon, cause a large amount of wastings of resources, after the attapulgite clay mine tailing is pulverized, be the attapulgite clay mine tailing, the present invention selects the particle fineness of attapulgite clay mine tailing≤0.20 millimeter.
Select the yellow ground, stone and the dregs the like waste that are scattered in the mortar that is scattered in construction work, concrete, brickbat, broken concrete, handling process, the present invention selects the particle fineness of building waste≤5.0 millimeters.
Volcanoclastic rock is the rock of the transitional type between magma lava and sedimentogeneous rock, wherein the composition more than 50% is comprised of the material of pyroclastic flow ejection, and these tephras are mainly the lava of premature coagulation on volcano, the rock formation that passage is burst on every side when volcanic eruption.The volcanoclastic rock mixture comprises landwaste, brilliant bits, glassiness bits, slurry bits, volcanic block (diameter is greater than 100 millimeters), volcanic gravel (diameter is greater than 2 millimeters) and volcanic ash (diameter is less than 2 millimeters), the volcanoclastic rock main chemical compositions is silicon-dioxide and aluminum oxide, the particle fineness of volcanoclastic rock mixture after the present invention selects and pulverizes≤10.0 millimeters.
The montmorillonite mine tailing is distributed in the lower floor in attapulgite clay ore deposit mostly, and the montmorillonite water-absorbent is strong, has plasticity-and agglutinating value(of coal), and the present invention selects the particle fineness of montmorillonite mine tailing≤0.2 millimeter.
Diatomite is fine and smooth, loose, light weight, porous, specific surface area is large, space is regular distribution, and stable chemical nature is a kind of natural nano aperture amorphous silicon material, but diatomite is made a low multiple use, the product of most enterprises comes from one-level soil, and two, three grades of soil are discarded in a large number, have caused serious waste of resources, also polluted environment, the present invention selects the particle fineness of diatomite mine tailing≤1.5 millimeters.
The cement selection silicate cement.
The present invention is achieved by following technical proposals:
1, the batching of unburned Attapulgite building waste insulating brick is comprised of following component by weight percentage: attapulgite clay mine tailing 5~20%, building waste 15~35%, volcanoclastic rock mixture 5~20%, montmorillonite mine tailing 5~15%, diatomite mine tailing 1~15%, cement 5~20% and water 10~40%;
The production method of described unburned Attapulgite building waste insulating brick: the batching of unburned Attapulgite building waste insulating brick is added in the two shaft pugmill mixer moved and stirs, after stirring, be transported in fully-automatic building block forming machine, be pressed into difform unburned Attapulgite building waste insulating brick work in-process, maintenance is carried out in conventional maintenance process according to cement products, is packaged as the finished product of unburned Attapulgite building waste insulating brick after 28 days;
Describedly be pressed into difform unburned Attapulgite building waste insulating brick work in-process, refer to the unburned Attapulgite building waste insulating brick work in-process that need to be pressed into square, rectangle, cylindrical, trilateral, ellipse, trapezoidal, quincunx, rhombus according to design.
Unburned Attapulgite building waste insulating brick has that intensity is high, the characteristics of good rigidly, light weight antidetonation, heat preservation energy-saving, sound-insulating and heat-insulating, fire protection flame retarding, weather resistance and anti-cracking waterproof.
In the batching of unburned Attapulgite building waste insulating brick, the various wastes of a large amount of employing, not only be conducive to improve resource utilization, turns waste into wealth, and can also reduce land occupation, and protection and environment purification are saved the energy, reduce production costs, and increase economic efficiency.
Unburned Attapulgite building waste insulating brick is applicable to the wall construction of various buildings
.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
1, the batching of unburned Attapulgite building waste insulating brick is comprised of following component by weight percentage: attapulgite clay mine tailing 15%, building waste 24%, volcanoclastic rock mixture 12%, montmorillonite mine tailing 8%, diatomite mine tailing 7%, cement 8% and water 26%;
The production method of described unburned Attapulgite building waste insulating brick: the batching of unburned Attapulgite building waste insulating brick is added in the two shaft pugmill mixer moved and stirs, after stirring, be transported in fully-automatic building block forming machine, be pressed into difform unburned Attapulgite building waste insulating brick work in-process, maintenance is carried out in conventional maintenance process according to cement products, is packaged as the finished product of unburned Attapulgite building waste insulating brick after 28 days;
Describedly be pressed into difform unburned Attapulgite building waste insulating brick work in-process, refer to according to design and need to be pressed into rectangular unburned Attapulgite building waste insulating brick work in-process.
