Abstract
The present invention relates to a high-blended gangue bulked light high-strength material and its production method. The composition of said high-strength material includes 20-50% of gangue, 78-45% of rock and 2-5% of foaming agent. The described rock is slate or shale, and the foaming agent is pearlite, vermiculite and calcium carbonate. The production method includes the following steps: breaking the prepared material, stirring them, grinding, sieving, placing the above-mentioned material into box bowl and roasting in the kiln so as to obtain the invented material.
Description
Technical field
The present invention relates to a kind of material and preparation method thereof, more particularly the present invention relates to a kind of material of construction and preparation method thereof, refer in particular to a kind of high volume coal gangue bulked light high-strength material and preparation method thereof, in International Patent Classification (IPC), should be divided into the E04C group.
Background technology
At present, various material of construction can buy on market, should these material of construction be that expanding economy has played enormous function, but existing material of construction also has weak point, what wherein performance was comparatively outstanding has: 1) the natural resources waste is serious, and especially outstanding is the land resources and the forest reserves of having wasted many preciousnesses.Also destroy the eubiosis when 2) being accompanied by the wasting of resources, caused the deterioration of global biosphere overall situation.In addition, meanwhile, along with expanding economy, especially along with a lot of solid waste have also been left in the development of mining economy, residuum of the mine tailing of coal gangue, various mineral and residuum thereof, building stone etc. for example.Above-mentioned solid waste has not only caused the waste of resource, has also destroyed environment simultaneously.Recently also occurred utilizing coal gangue or flyash to produce the technology of solid brick, hollow brick, building block, this is a progress, but scientific and technological content is low, function singleness, defective is obvious, range of application is narrow, and be mostly to rest on low-level the copying of existing low grade products, market outlook cause anxiety, and manufacturing enterprise is difficult to for continuous.
Summary of the invention and embodiment the objective of the invention is to: at the deficiency of prior art, provide a kind of high volume coal gangue bulked light high-strength materials solid waste, that saving is natural resource, that meet environment protection, quality is good and preparation method thereof that utilize in a large number.
The objective of the invention is to be achieved through the following technical solutions:
Principal feature is: described Materials with High Strength comprises coal gangue, rock and whipping agent, and the weight percent of described material is respectively:
Coal gangue 20-50%,
Rock 78-45%,
Whipping agent 2-5%.
The weight percent of described material can be respectively:
Coal gangue 30%,
Rock 67%,
Whipping agent 3%.
Described rock is slate, shale.
Described whipping agent is perlite, vermiculite, lime carbonate.
The making method of described high volume coal gangue bulked light high-strength material is as follows:
1) get material ready by following weight percent:
Coal gangue 20-50%,
Rock 78-45%,
Whipping agent 2-5%;
2) the above-mentioned material fragmentation of getting ready, stirring, grinding;
3) material broken, that stir, grind is crossed 100 purposes sieve;
4) material after above-mentioned the sieving is packed in the saggar;
5) material of the saggar of packing into is put into roasting in kilns according to following technology:
Temperature ℃ 60 100 250 400 600 800 1,000 1,200 1,200 1,200 800 600 450 380 200 50
Time minutes 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150;
6) material after the roasting is taken out from saggar, pile up neat, standby.
Because the present invention has adopted technique scheme, described high volume coal gangue bulked light high-strength material is functional, and its main performance index is as follows:
Unit weight P (kg/m
3) 200＜P＜1800
Ultimate compression strength MPa＞2
Folding strength MPa＞1.5
Water-intake rate % 0.8＜water-intake rate＜1.5
Thermal conductivity W/MK 0.05＜thermal conductivity＜0.3
Incendivity reaches GB8624 A level
Described high volume coal gangue bulked light high-strength material expanded performance is good, this material has good porous performance under well behaved prerequisite, described hole can be the composite holes that combines with little closed pores of totally-enclosed hole, semiclosed hole, the half-open combined hole of semi-closure, big closed pores etc.
The making method of described high volume coal gangue bulked light high-strength material is fairly simple, and roasting time is quite short, and very is fit to automation size production, and efficient is quite high, thereby production cost is low.What is more important: this product can be saved natural resource in a large number, is the product of an environmental protection.
Need to prove, in calcining process, can put into the saggar direct roasting to the starting material of getting ready and become blank, cut into desired material of construction then as required, this also is an important advantage of the present invention, because this material of construction is particularly suitable for cutting.
Also can put into the mould direct roasting to the starting material of getting ready and become needed material of construction.That is to say that bakes to burn the article becomes needed product.
Employed equipment can be selected tunnel furnace or roller kiln in calcining process, and employed fuel can be Sweet natural gas, also can be liquefied petroleum gas (LPG), can also adopt the lower light hydrocarbon fuel of price, and this helps reducing production costs.
Experiment showed, that this material of construction both can be used as the material of construction of load-bearing, also can be used as nonweight-bearing material of construction.Advantage in light weight, that intensity is big, hardness is high, wear resistance is good that this material of construction has.Difference as required in addition, described material of construction can make that intensity is different, that pore size is different, the material of construction of multi-layer compound structures that have or not facing, that physicochemical property is different.
In addition, this material of construction excellent heat insulating performance is particularly suitable for the insulation of buildings and heat insulation, also is suitable for fire prevention.In addition, the sound insulation and noise reduction performance of this material of construction is also quite good, therefore also is specially adapted to the insulating course in house.Also have, the water resistance of this material of construction and shielding property are also more outstanding, particularly suitable under the environment harsh conditions.
