Description
Technical field
The present invention relates to steam-pressing brisk technical field, more particularly to a kind of preparation method of environmentally friendly steam-pressing brisk.
Background technology
Building brick in the past is mostly fired brick, and materials are not easy, complex manufacturing and high energy consumption, can be produced in production process
Raw pernicious gas, big to the potential pollution of air, country of China wall, which is corrected, have been required to forbid in all cities in the whole nation in 2010
Using clay brick, while strict limitation fired brick project.Steam-pressing brisk obtains more and more extensive use at present, now with fine coal
Steam-pressing brisk prepared by ash, its shortcoming is easy to crack, and compression strength is poor.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of preparation method of environmentally friendly steam-pressing brisk, utilizes
Fine coal waste slag produces steam-pressing brisk, optimization of ecological environment；And cost is cheap, gained finished bricks intensity is big, not easy to crack, pressure-bearing
Ability is strong.
A kind of preparation method of environmentally friendly steam-pressing brisk proposed by the present invention, comprises the following steps：
S1, cement, coconut shell flour, water mixing, ageing are added into pre-treating fly ash, rolling, extrusion forming obtains adobe；
S2, it will be sent into after adobe initial curing in still kettle, temperature elevation and keep pressure, decompression, cooling obtains environmentally friendly steam-pressing brisk.
Preferably, in S1, pre-treating fly ash, cement, coconut shell flour, the weight ratio of water are 70-90：20-40：10-20：
60-100。
Preferably, in S1, pre-treating fly ash is prepared by following technique：Flyash is dried, adds carragheen, water mixing
Uniformly, crosslinked starch, castor oil acid stirring are added, filtering, is dried to obtain pre-treating fly ash.
Preferably, in S1, pre-treating fly ash is prepared by following technique：50-70 parts flyash is dried by weight, added
Enter 10-16 parts carragheen, 120-180 part water is well mixed, addition 6-12 parts crosslinked starch, the stirring of 10-15 parts castor oil acid, mistake
Filter, is dried to obtain pre-treating fly ash.
Preferably, in S1, pre-treating fly ash is prepared by following technique：50-70 parts flyash is dried by weight, added
Enter 10-16 parts carragheen, 120-180 part water is well mixed, addition 6-12 parts crosslinked starch, 10-15 parts castor oil acid stirring 10-
20min, mixing speed 11000-14000r/min, filtering, 140-160 DEG C is dried to obtain pre-treating fly ash.
Preferably, in S2, it will be sent into after adobe initial curing in still kettle, be warming up to 220-240 DEG C of pressurize 2-3h, drop
Pressure, cooling obtain environmentally friendly steam-pressing brisk.
The invention belongs to bring environmental pollution under comprehensive control, steam-pressing brisk is produced using fine coal waste slag, can thus be mitigated
The pollution to air, soil and water caused by flyash, optimization of ecological environment；And cost is cheap, gained finished bricks intensity
Greatly, not easy to crack, bearing capacity is strong, and environmental protection concept is incorporated into production, environmental protection.
The present invention by flyash after drying, carragheen effectively can be penetrated into inside flyash, further with octenyl
Succinic acid starch ester compounds, and is not only not easy by enzyme effect, and emulsifying activity is high, and can prevent old caused by illumination, oxygen etc.
Change acts on, and caking property is good；The Combination of pre-treating fly ash and cement, coconut shell flour is good, and interface compatibility is good, by mutually viscous
Close, together, viscosity is big for internal bond, and stability is good, is not in that graininess comes off, product internal structure stability.Effectively
The mould brick for preventing from making ftractures, and avoids the addition of flyash from influenceing the performance of finished bricks, rate of reducing the number of rejects and seconds, improves finished bricks
Quality, the intensity and bearing strength of steam-pressing brisk are good.
The present invention has the small characteristic of heat transfer coefficient, and its heat transfer coefficient is 0.42, compression strength 36.1MPa, and anti-folding is strong
Spend for 8.6MPa, anti-freezing property is good, carbonation coefficient 1.4, drying shrinkage value 0.22, meets standard；Powder institute of the present invention
The strength grade of coal ash steam-pressing brisk is obtained up to MU30 ranks；Show by atmospheric exposure test, self-heat conserving steam-pressing brisk of the invention warp
Cross 150 Re-rain loop cycle, 5 hot-cold loop cycles, surface without foaming, without peel off, free from flaw phenomenon, it is superior in quality.
