Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of high intensity fired shale-gangue perforated brick.
Background technology
The use of brick and tile material is up to 85% or so in China's residential housing, and what tradition used is mostly clay solid brick, often
Year not only damages a large amount of soils, but also destroys ecological environment, more heavy, and the poor-performings such as antidetonation, heat preservation, sound insulation, difficult
To meet existing building demand.Therefore, it is badly in need of developing novel wall material to replace traditional solid brick, at present, lightweight,
The porous brick high-strength, shock resistance is good early has shown that its superiority as new materials for wall.Porous brick refer to clay,
Shale, flyash are primary raw material, and through being molded, roasting, hole ratio is equal to or more than 15%, and pass is circular hole or not rounded
Hole, due to the size in hole is small and quantity more be referred to as porous brick, be primarily adapted for use in bearing wall.Porous brick and traditional solid brick phase
Than that can make building weight reduction 1/3 or so, save clay 20-30%, save fuel 10-20%, and burn till rate height, cost
20% is reduced, construction efficiency improves 40%, and can improve the heat-insulated and sound insulation property of brick, in identical thermal property requirement
Under, bat can be thinned with the thickness of wall body of hollow brick masonry and act on, so promoting the use of porous brick with great economic implications.
On the other hand, in order to make full use of solid waste, national energy-saving emission reduction, the call turned waste into wealth are responded, by original
Other raw materials are admixed in material and have become the emphasis studied for people, key technology is in the brick in ensureing that porous brick meets building trade
Performance requirements.
The content of the invention
In view of the above problems, the present invention proposes a kind of high intensity fired shale-gangue perforated brick, by rational
Raw material proportioning, the flowing effectively increased between component are coupled, and comprehensive performance significantly improves, and product compression strength obtained is more than
28.4MPa, hole ratio is more than 35%, and takes full advantage of trade waste, environmental protection and saving, high financial profit, and suitable industry pushes away
Extensively.
In order to realize above-mentioned purpose, the present invention uses following technical solution：
A kind of high intensity fired shale-gangue perforated brick, including following percentage composition component：Shale 15-35%, waste plastic
Particle 6-15%, vermiculite power 4-7%, alkaline slag 5-10%, magnesium borate crystal whisker 0.5-1.8%, gangue surplus.
Preferably, modification infusorial earth 0-10%, dispersant 0-3% are further included.
Preferably, high intensity fired shale-gangue perforated brick, including following percentage composition component：Shale 30%, waste plastic
Particle 10%, vermiculite power 5%, alkaline slag 8%, magnesium borate crystal whisker 1.0%, modification infusorial earth 5%, dispersant 2%, gangue
Surplus.
Preferably, modification infusorial earth preparation process is as follows：Diatomite is taken to be placed in ball mill and is ground to grain size less than 5 μm,
Then the polyvinyl alcohol water solution of diatomite quality 20-30% is added in thereto, after stirring evenly, 80 DEG C of isothermal holding 3-4h,
Then the surface modifier of diatomite quality 0.5-1% is added in thereto, first 50 DEG C of sonic oscillation 20min, then isothermal holding
Then 2-3h is dried under reduced pressure to water content as 5 ± 0.5% to get modification infusorial earth for 50 DEG C.
Preferably, polyvinyl alcohol mass percentage is 1.5-3.5% in the polyvinyl alcohol water solution, and the surface changes
Property agent be mass ratio 1：N- acyl aminos hydrochlorate, the composition of magnesium titanate coupling agent of 0.2-0.4.
Preferably, the waste plastic particle is one or more in discarded PP, PE, PVC, PS, ABS, PMMA plastics
Composition, waste plastic grain diameter are 1-2mm.
Preferably, the dispersant is mass ratio 1：0.5-1：The stearic acid of 1-3, alkylphenol polyoxyethylene ether, benzene second
The composition of alkene copolymer-maleic anhydride.
High intensity fired shale-gangue perforated brick preparation method of the present invention is as follows：Raw material is first weighed by weight, by shale, alkali
Property slag, gangue crushed 10-15 mesh sieves, be then fed into mixer plus water blending, 20rpm stirrings 30min obtain mixture,
It is spare；Waste plastic is heated to melting, then adds in vermiculite power and magnesium borate crystal whisker thereto, insulated and stirred 5-10min, so
8-10h is placed in heat preservation under the conditions of postcooling curing is placed on 60-70 DEG C, is re-fed into kneading machine, and mixing 3-4min is extruded to make
Grain obtains particulate material, spare；Mixture, particulate material and other surplus materials are blended, water filling in mixer is placed in and is sufficiently stirred, obtain
Slurry is then fed into ageing storehouse and is aged 2 days, is sent into after taking-up in vacuum brick making machine, squeezes to obtain porous adobe, naturally dry；
The porous adobe dried is sent into calcining kiln and is sintered to get high intensity fired shale-gangue perforated brick.
