The invention discloses a kind of slag, slag grinding aid activator.It is made up of the raw material of following mass percent: lactose 7-15%, propylene glycol 6-14%, ethylene glycol 5-15%, polymeric amide 4-10%, oleic acid 3-7%, Sodium sulfate anhydrous.min(99) 6-13%, caustic soda 5-12%, composite assistant 2-4%, and all the other are water.The present invention is used for grinding slag, slag, can improve mill hourly output 10-16%, reduces grinding pow consumption 7-13%, can also improve slag, activity of steel slag index more than 8% simultaneously.
Description
Technical field:
The present invention relates generally to slag, slag micro powder production field, particularly relates to a kind of slag, slag grinding aid activator.
Background technology:
Slag is the waste residue that blast furnace ironmaking produces, because it has good potential hydration activity, be widely used in, among cement, concrete, not only can saving cement clinker as adulterant, a series of performances such as concrete weather resistance, mobility, hydration heat can also be improved.Present slag has become a kind of important building materials raw material.
Slag is the waste residue that blast furnace steel-making produces, and its physicochemical property are similar to slag, but its specific activity slag is low.Because slag resource is nervous, and price is higher, and present slag micro powder is more and more applied in cement and concrete as adulterant.
The necessary grinding of slag, slag is to specific surface area 400m
2/ more than kg, its hydration activity just can give full play of.But slag, slag grindability are poor, and Bond work index is up to more than 23.Therefore, the power consumption of production slag, slag micro powder often very high (ball mill power consumption is generally more than 75kWh/ ton).
Grinding aid on domestic market is almost entirely for cement grinding, and they do not have grinding-aid effect substantially for the production of slag.In recent years, domestic also had some grinding aid manufacturing enterprises to develop slag grinding aid, but mostly grinding-aid effect is uncertain, and also not obvious to the excitation of activity, the grinding for slag then has no grinding aid function.
Therefore, provide one significantly can improve slag, slag mill hourly output, reduce slag, steel slag grinding production cost, and can improve slag, activity of steel slag grinding aid activator very necessary.
Summary of the invention:
The object of the invention is exactly the defect in order to make up prior art, provides a kind of slag, slag mill hourly output, energy-saving and cost-reducing and can improve a kind of grinding aid activator of slag, hydration activity of steel slag of significantly improving.
The present invention is achieved by the following technical solutions:
A kind of slag, slag grinding aid activator, it is characterized in that, it is made up of the raw material of following mass percent: lactose 7-15%, propylene glycol 6-14%, ethylene glycol 5-15%, polymeric amide 4-10%, oleic acid 3-7%, Sodium sulfate anhydrous.min(99) 6-13%, caustic soda 5-12%, composite assistant 2-4%, and all the other are water;
The preparation method of described composite assistant is as follows: a, in mass ratio 3-6:2-4:1-2 take attapulgite, agalmatolite and illite, the hydrochloric acid soln that concentration is 15-20% is put into after mixing, heating in water bath is to 70-80 DEG C, and insulation 0.5-1h, takes out and be washed with distilled water to neutrality, wet ball grinding 12-24h, dry, after 820-860 DEG C of calcining 1-2h, be warming up to 1200-1250 DEG C and continue calcining 0.5-1h, take out while hot and shrend, obtain particle; B, above-mentioned obtained particle was pulverized 200-300 mesh sieve, then the slurries that solid content is 55-65% are made in the making beating that adds water, add the carboxymethyl starch of the sodium polyacrylate of 3-5%, the polysorbate60 of 1-2%, the sodium alginate of 2-3% and 2-3%, 2000-3000rpm speed lapping 10-15min, spray-dried powders; Add the calcium lignin sulphonate of 2-3%, the stearic acid sodium of 1-2%, the APTES of 0.5-1% and the jade powder of 1-2% in c, above-mentioned obtained powder, 1000-1500rpm high speed ball milling 20-30min, dry.
The preparation method of described grinding aid activator is as follows: the tap water injecting 20-35 DEG C in a kettle., add Sodium sulfate anhydrous.min(99), caustic soda stirs, then add lactose, propylene glycol, ethylene glycol, polymeric amide, oleic acid, composite assistant stir, obtain slag, slag grinding aid activator product.
The suitable incorporation of described grinding aid activator in grinding is the 0.05-0.1% of slag, slag weight.
Described grinding aid activator can be used for ball mill grinding, vertical mill grinding and roll squeezer grinding.
The present invention develops according to the fine-grinding theory of slag, slag.The fine-grinding theory of modern slag, slag is thought, when material by grinding to certain fineness (specific surface area 260m
2/ more than kg) after, just start between fine powder to gather, conglomeration, very adverse influence is caused to the further grinding of material.Gather, the reason of conglomeration is that material can be produced huge surface free energy by after refinement.Present invention uses kinds of surface promoting agent, they are adsorbed on the surface of powder granule, and its surface free energy is significantly reduced, and make no longer to gather between subparticle, conglomeration.Invention also uses tenderizer simultaneously, make slag, slag surface softening, improve its grindability, reach the object improving mill efficiency.
The present invention develops according to the hydrated theory of slag, slag.The hydrated theory of slag, slag is thought, slag, slag itself can not aquation, but has potential hydration activity, exciting agent interaction energy fast hydration and produce certain intensity.The present invention is theoretical accordingly, employs multiple exciting agent, and their synergies, carry out strong exciting to slag, slag, its hydration activity is significantly improved.
Advantage of the present invention is:
1, the present invention can improve slag, slag mill hourly output 10-16%, and energy conservation and consumption reduction effects is obvious.Therefore the grinding cost of slag, slag micro powder can significantly be reduced.
2, the present invention can improve slag, hydration activity of steel slag more than 8%.
Generally speaking, the present invention is with low cost, excellent property, Increasing Production and Energy Saving Be very effective the grinding aid activator with good society economic benefit.
