Abstract
The invention relates to the technical field of mineral grinding, particularly to a composite grinding aid for mineral slag liquid. The composite grinding aid is prepared from the following raw materials in parts by weight: 10-20 parts of triethanolamine, 15-20 parts of isopropanolamine, 8-15 parts of bamboo vinegar, 2-7 parts of cellulose ether and 33-43 parts of deionized water. The composite grinding aid for mineral slag liquid, provided by the invention, can improve the grindability of mineral powder, increase the activity index of superfine slag powder, increase the yield of an abrasive grinding machine, reduce the power consumption per unit of time and further prolong the storage period.
Description
Technical field
The present invention relates to mineral grinding technical field, particularly a kind of slag liquid composite grinding aids.
Background technology
The melts being main component with Calucium Silicate powder, calcium aluminate of discharging when slag is ironmaking, the granular active material formed after quenching through shrend.Generally contain the glassy phase of 80 ~ 90%, its essential mineral is Dicalcium Phosphate (Feed Grade) (C
2s), gehlenite (C
2aS), akermanite (C
2mS
2), lime feldspar (CAS
2) etc.The chemical composition of slag is generally CaO
35 ~ 45%, SiO
225 ~ 40%, Al
2o
36 ~ 15%, FeO0.5 ~ 1%.Quality coefficient (the CaO+MgO+Al of slag
2o
3)/(SiO
2+ MnO+TiO
2) larger, the activity of slag is higher, i.e. CaO, Al
2o
3content is high, SiO
2the slag reactivity that content is low is high.Be a kind of " low calcium height silicon " grog, have excellent " latent hydraulicity ".The quality coefficient that standard GB/T/T203 is given for the granulated blast-furnace slag in cement and concrete should be greater than 1.2, MnO content and be not more than 2.0%.
The slag high-activity micro powder prepared after fine-grinding by slag has become that at present preparation is high-strength, one of indispensable important materials in high-performance, high corrosion resistant concrete process.In concrete system, slag micropowder substitutes cement by a certain percentage, significantly can improve concrete performance on the one hand, significantly can reduce concrete folk prescription production cost on the other hand, obtain good economic benefit.Slag micropowder is introduced concrete and significantly can be reduced hydration heat and effectively suppress chemical shrinkage and cracking, improve concrete construction performance (as mobility, workability, pumpability etc.) and weather resistance, prevent alkali-collection reaction (AAR), improve concrete impervious, freeze proof, erosion-resisting characteristics, increase concrete compaction degree and structural strength simultaneously.
Vitreum content in slag is more, and its latent hydraulicity is also better, but its grindability is also poorer, and mill efficiency is low, and the energy consumption that slag separate grinding consumes is higher.In actual industrial production, usually through adding grinding aid to address this problem in grinding process.The typical liquid slag grinding aid of domestic one, is characterized in that it obtains through magnetizing assembly activation treatment primarily of the mixing of trolamine, polycarboxylate water-reducer and calcium hydroxide saturated solution raw material.External one typical liquid slag grinding aid patent, it forms primarily of organosilicon polymer (siloxanes).The formula composition of these liquid grinding aids all also exists some defects: due to the worsening shortages of world petroleum resource, cause the price of the main raw material(s) trolamine of grinding aid and organosilicon polymer (certain siloxanes) also constantly soaring, the effective slag grinding aid product seeking a kind of relatively low cost is domestic grinding aid industry problem in urgent need to solve, mill hourly output puies forward product amplitude more than 14% to also have slag micropowder manufacturing enterprise to require, in the hope of reducing power consumption further, save energy.
Summary of the invention

For achieving the above object, technical scheme to be solved by this invention is:
The invention provides a kind of slag liquid composite grinding aids, be made up of the raw material of following weight part: trolamine 10 ~ 20 parts, α-amino isopropyl alcohol 15 ~ 20 parts, bamboo vinegar liquid 8 ~ 15 parts, ether of cellulose 2 ~ 7 parts, deionized water 33 ~ 43 parts.
Slag liquid composite grinding aids of the present invention, is made up of the raw material of following weight part: trolamine 15 parts, α-amino isopropyl alcohol 18 parts, bamboo vinegar liquid 11 parts, ether of cellulose 5 parts, deionized water 38 parts.
The present invention also provides the preparation method of slag liquid composite grinding aids, comprises following preparation process: take whole raw material by formula ratio, is joined by bamboo vinegar liquid in deionized water, becomes stirring limit and is warming up to 30 ~ 38 DEG C; Add trolamine and α-amino isopropyl alcohol again, insulated and stirred 5 ~ 10min, then be warming up to 40 ~ 44 DEG C, add ether of cellulose, stir 3 ~ 6min, cooling, filters.
Beneficial effect of the present invention is:
1, slag liquid composite grinding aids of the present invention is liquid, and each component can mix, and can effectively improve breeze grindability.
2, slag liquid composite grinding aids of the present invention joins in breeze and carries out grinding, output increased more than 29%.
3, needed for slag liquid composite grinding aids of the present invention, volume is few, only need add 0.1 ~ 0.3%, just can obtain good grinding aid performance, and better can improve slag properties.
4, slag liquid composite grinding aids of the present invention can significantly improve the activity index of slag micropowder, and 28d activity index rises to S85 level from S75 level, improves a rank.
5, slag liquid composite grinding aids of the present invention can significantly improve slag micropowder specific surface area, and its specific surface area increases by 25 ~ 39 ㎡/kg, and 45 μm of screen over-sizes reduce by 1.59 ~ 2.95%.
