Description
Technical field
The present invention relates to cement additive technical field, specifically a kind of cement grinding aid and preparation method thereof of the Wingdale that can adulterate in a large number.
Background technology
Along with the enforcement of the strategy of sustainable development, resource, the energy, environmental problem greatly restrict the development of Cement industry.The cement grinding aid of few volume just can improve cement granules grating, improve mill efficiency and Cement Quality index.Therefore, grinding aid has irreplaceable vital role to Sustainable Development of Cement Industry.
Wingdale is that cement mill is easy to acquisition, the most cheap mixing material most, can also improve a series of performances of cement simultaneously, comprise the water-retentivity etc. reducing cement normal consistency water consumption, raising cement and water reducer compatibility, improve cement.Utilize the levigate rear blended material as manufacture of cement of natural low-cost resource Wingdale, compared with slag, flyash, volcanic ash, because its resource is guaranteed, cheap, convenient transportation, need not dry, and more demonstrates huge economic worth to Cement industry, so a lot of cement mill, in order to reduce the cost, is wanted to add large quantities of lime stone at present.
China just starts in the phase early 1980s research that Wingdale is used as mixing material, and has carried out practical engineering application.The Wingdale mixing about 5% ~ 8% in cement replaces grog, can improve cement early strength, simultaneously not obvious reduction cement later strength.But when limestone addition is larger, compare with slag, flyash etc., Wingdale can reduce cement later strength significantly.Improving the measure that high limestone addition cement later strength is on the low side, is that some chemistry of admixture adds when manufacture of cement.Therefore, how that just can accomplish to add Wingdale as much as possible, and does not affect the study hotspot that Cement Quality has become this field.
Summary of the invention
The object of the invention is to for above-mentioned defect of the prior art, a kind of cement grinding aid of the Wingdale that can adulterate in a large number is provided, this grinding aid not only can increase substantially the blending amount of mixture material such as Wingdale in cement, reduce clinker dosage, and fineness and the bending and compressive strength of cement can be improved, and cement performance can be improved and improve output, reduction manufacture of cement cost.
For achieving the above object, present invention employs following technical scheme:
Can be adulterated the cement grinding aid of Wingdale in a large number, and each component is by mass percentage:
Wherein, the cement grinding aid of a kind of Wingdale that can adulterate in a large number described above, its preferred each component is by mass percentage:
The cement grinding aid of a kind of Wingdale that can adulterate in a large number described above, its most preferred each component is by mass percentage:
Preferably, described auxiliary agent is one or more in carboxylic acid, Sulfite lignin, alkylsulfonate.
Preferably, described sulfonated lignin are wood pulp, bamboo pulp or straw pulp spentsulfiteliquor enriched product.
Another object of the present invention is to provide the preparation method of this grinding aid.
Can be adulterated the preparation method of cement grinding aid of Wingdale in a large number, comprises the steps:
1) by trolamine, two polyglycerols and water in mass ratio for the ratio of 1:1 ~ 1:6 carries out being mixed to form solution, then heat, heating temperatures to 50 ~ 55 DEG C,
2) respectively sodium sulfate, sodium-chlor, sugar ether, calcium formiate, Tai-Ace S 150, auxiliary agent are joined in above-mentioned solution;
3) cool the temperature to less than 30 DEG C, Sodium hexametaphosphate 99, sodium lauryl sulphate are joined in above-mentioned solution, insulation;
4) this solution is carried out stirring and dissolving, to be mixed evenly, cooling, filter after finished product.
In formula of the present invention: tri-isopropanolamine belongs to alkanol amine substance, it is a kind of alcohol amine compound with amido and alcohol hydroxyl group, both contained amino in molecule due to it, again containing hydroxyl, therefore there is the over-all properties of amine and alcohol, tri-isopropanolamine is as tensio-active agent, the healing of powder granule section and particle agglomeration can be reduced, improve powder granule dispersiveness and mobility, reduce the generation of bag ball phenomenon, improve mill efficiency, in use can also reduce water consumption, improve the mobility of cement and improve concrete intensity; Calcium formiate is a kind of neutrality, has the hardening accelerator of short solidifying function; Trolamine can form inner complex soluble in water with hydrated cementitious system cationic, and cement particle surface formed many can fusing point, cause and accelerate with the speed of response of gypsum, hydrated calcium aluminate sulfate amount increases, be conducive to condensation and closely knit, thus improve getting up early intensity, simultaneously owing to forming the complex compound of instability in cement hydration process, be that calcium hydroxide degree of super saturation improves, thus improve compactness and the intensity of Behavior of Hardened Cement Paste; Appropriate Sodium hexametaphosphate 99 add the performance that not only can not affect cement, and dispersiveness and the mobility of cement can be improved, improve mill efficiency and the powder separating machine grinding efficiency of grinding machine.Appropriate dodecylbenzene add mobility, the water-retentivity that can improve cement, and with the compatibility of admixture.Sugar ether can significantly improve Wingdale at complex cement loading level, and grinding aid, through the compound action of each composition, reaches grinding aid, improves the effect of Wingdale loading level in cement.
Compared to prior art, advantage of the present invention is:
1, each raw material synergy in grinding aid of the present invention, can not only increase substantially Wingdale incorporation in cement, the volume of Wingdale improves 20 ~ 30%, can greatly reduce the consumption of grog, reduce costs.
2, the volume of grinding aid of the present invention in cement only have ten thousand/several, do not affect cement properties and prescribed value, can mill efficiency be improved, strength of cement, also can improve the perviousness of cement, good fluidity, significantly can reduce product cost, grinding-aid effect is more obvious, improve Working environment, and obviously can improve the performance of cement, production technique is simple, and product can standing storage.
2, cement grinding aid of the present invention, prove through test, unit-hour output can improve about 25 ~ 30%.
