Description
Technical field
The present invention relates to a kind of activity booster for being used for slag, slag and preparation method thereof.
Background technology
Slag and slag are all waste residues caused by steel industry.Slag is widely used in cement concrete row so far
Industry, but slag is but seldom utilized, and can directly be handled without particularly effective method, and these slags produced,
Common processing method is all to excavate entrucking using equipment such as load wagon, power shovels, then delivers to Dumping Sites landfill, such slag landfill
A large amount of soils are taken, and the recyclable materials in slag can not be made full use of again, while wasting resource, also easily to ring
Cause irreversible destruction and pollution in border.And their physicochemical properties are similar to clinker, the early activity of slag compared with
Low, later stage activity is very high, and the activity of slag is lower than slag, so using difficult relatively more.
Under Present Global climate warming, the surging background of emission reduction cry, for developing country, energy profit is improved
With efficiency, reduce unnecessary energy waste, be relatively preferably, quick result, more practicable energy-saving and emission-reduction mode.It is existing
There is technology although to have various functions grinding aid, but Vertical Mill is not applied for due to may be only available for ball milling, what is also had does not consider into
This, it is expensive to be not suitable for practical application, and also existing additive is more using the compound containing halide ion, to equipment
Seriously corroded.What is more is also added into poisonous and hazardous material in combustion-supporting agent for fuel coal.Such as：
Chinese patent CN105731855 instantly grinding scoria grinding aids, by inorganic salts calcium chloride and polyalcohol and polymerized polyalcohol group
Into only having a grind -aiding effect, and to contain substantial amounts of halide ion very serious to equipment corrosion for calcium chloride.
Above-mentioned prior art, all it can possess the problem of more or less.Therefore, it is necessary to develop a kind of efficient, inexpensive, really steady
Surely Furnace Slag Steel Slag mixing Vertical Mill grinding aid that can be permanently effective, grind -aiding effect is improved, excites the activity of complex ore slag.
The content of the invention
Purpose：To solve the deficiencies in the prior art, the present invention provides a kind of for slag, the activity booster of slag, energy
Enough slag is set to excite activity of steel slag, its chemical stability is good, and addition content is low, nontoxic pollution-free, can make slag in grinding process
The specific surface area of powder and slag powders increases, and changes slag crystal inside, and lattice produces displacement defect, generates soluble in water
Non-lattice structure, water is entered the internal dissolving aquation for accelerating internal calcium ions, C-S-H gelling systems are generated, so as to carry
High intensity.
Technical scheme：In order to solve the above technical problems, the technical solution adopted by the present invention is：
It is a kind of to be used for slag, the activity booster of slag, react multiple by triethanolamine, glycerine, catalyst, alkali, inorganic salts and water
With mixing, its raw material, which forms, is：Modified triethanolamine is 8%~15%, and alkali is 3%~8%, and triethanolamine is 6%~15%, nothing
Machine salt is 15%~29%, and surplus is water, total amount 100%；The percentage is mass percent；The modified triethanolamine is
Triethanolamine and the glycerine synthetic reaction in the presence of catalyst are made.
It is preferably, described to be used for slag, the activity booster of slag, it is characterised in that：The triethanolamine
Quality purity is 85%~99%.
It is preferably, described to be used for slag, the activity booster of slag, it is characterised in that：The qualities of glycerin
Purity is 95%~99%.
It is preferably, described to be used for slag, the activity booster of slag, it is characterised in that：The catalyst is
The concentrated sulfuric acid.
It is preferably, described to be used for slag, the activity booster of slag, it is characterised in that：The alkali is piece alkali
Sodium hydroxide.
It is preferably, described to be used for slag, the activity booster of slag, it is characterised in that：The inorganic salts are
Sodium thiosulfate and sodium acetate.
The present invention also provides the described preparation method for slag, the activity booster of slag, and its step is：
The first step, prepare modified triethanolamine：It will be stirred in triethanolamine and glycerine in molar ratio 1 to 1 addition reactor
Mix, after adding the concentrated sulfuric acid of total mass fraction 1% into system again after stirring, after 2 hours, synthetic reaction terminates stirring reaction,
Obtain modified triethanolamine；
Second step, by the modified triethanolamine mass percent prepared be 8%~15%, alkali mass percent be 3%~8%, three
Monoethanolamine mass percent is 6%~15%, and inorganic salts mass percent is 15%~29%, and surplus is water, total amount 100%；Described hundred
It is mass percent to divide ratio, is produced.
Beneficial effect：Provided by the present invention for slag, the activity booster of slag, use what is synthesized according to demand to help
Its chemical stability of agent is good, does not contain the halide ion of etching apparatus, on the one hand makes steel-making slag powder and slag powders in grinding process
Specific surface area increases, and changes slag crystal inside, and lattice produces displacement defect, generates non-lattice structure soluble in water,
Water is entered the internal dissolving aquation for accelerating internal calcium ions, C-S-H gelling systems are generated, so as to improve intensity.It is another
Evaporation rate is very slow all between 240~300 DEG C for the drying temperature of aspect Vertical Mill, can play grind -aiding effect, excite grandidierite
The activity of slag.With advantages below：
1）Actual amount is less than common slag grinding aid, and its addition is only the dosage of slag and slag combination grinding amount
0.04%-0.08%；
2）Chemical stability is preferable, improves the grinding aid of Furnace Slag Steel Slag, excites the activity of slag；
3）Price is low, non-corrosiveness, "dead", nontoxic, is not belonging to hazardous chemical.
