Abstract
The invention relates to a liquid cement grinding aid for improving the adaptability of cement and concrete. The grinding aid comprises the following components: 20 to 30% of mixed alcohol, 4 to 10% of sodium tripolyphosphate, 17 to 25% of ZK-RJD-1 mother liquid, 19 to 27% of dual ethanol monoisopropanolamine, 5 to 10% of methyl alkenyl polyoxyethylene ether, 5 to 10% of sodium gluconate, and 1 to 5% of GDU-1 air entraining agents. Meanwhile, the invention also provides a preparing method of the liquid cement grinding aid for improving the adaptability of cement and concrete. For the grinding aid, the mixed alcohol, the ZK-RJD-1 mother liquid and the dual ethanol monoisopropanolamine are used for fully replacing triethanolamine, so that the production cost of the cement grinding aid is reduced, the strength of cement after 3 days and 28 days is better than that of the triethanolamine, and the usability of the cement grinding aid is effectively improved; the GDU-1 air entraining agents are used to effectively improve the grinding capacity of a cement grinding mill, and the power consumption cost is saved for a cement production unit; the methyl alkenyl polyoxyethylene ether is used to be matched with the sodium gluconate to reduce the water requirement of the normal consistency of the cement, and the flowing ability of the cement is improved.
Description
technical field:
The present invention relates to cement grinding aid technical field, particularly a kind of adaptive liquid cement grinding additive of cement and concrete and preparation method thereof that improves.
background technology:
In the grinding process of cement clinker, add a small amount of additional substance (material of liquid or solid), can significantly improve mill efficiency or reduce energy consumption, and don't this chemical additive additional substance of infringement cement performance is commonly referred to as: cement grinding aid.
Cement grinding aid is a kind of chemical additive that improves cement grinding effect and performance, can significantly improve cement unit-hour output, each length of time strength of cement, improves its mobility.Cement grinding aid can significantly reduce the electrostatic adhesion bag ball phenomenon forming in grinding process, and can reduce the coalescent trend again of the ultra-fine grain forming in grinding process.Cement grinding aid also can significantly improve cement fluidity, improves the grinding effect of grinding machine and the grinding efficiency of powder separating machine, thereby reduces grinding energy.The cement that uses grinding aid to produce has the coalescent trend of lower compacting, thereby is conducive to the handling of cement, and can reduce the wall cling phenomenon of cement silo.As a kind of chemical additive, grinding aid can improve cement granules and distributes and excite aquation power, thereby improves cement early strength and later strength.
At present, the cement grinding aid of domestic research and application, has liquid grinding aid and solid grinding aid, and its basal component mostly belongs to organic surface-active substance.Be specially: trolamine, Diethylene Glycol, ethylene glycol, sulfonated lignin, formic acid, stearic acid, oleic acid, Sodium dodecylbenzene sulfonate etc.Wherein, it is the most frequent that trolamine uses, because trolamine price is high, therefore each producer is all attempting finding a kind of substitute, existing trial is all undesirable, although cost, but often cause the decline of cement grinding aid effect, cement and concrete adaptability are reduced.
summary of the invention:
Given this, be necessary to allocate one not containing trolamine and improve the adaptive liquid cement grinding additive of cement and concrete, its preparation method is provided simultaneously.
A kind of adaptive liquid cement grinding additive of cement and concrete that improves, comprises following composition:
Mixed alcohol 20 ~ 30%
Tripoly phosphate sodium STPP 4 ~ 10%
ZK-RJD-1 type mother liquor 17 ~ 25%
Di-alcohol monoisopropanolamine 19 ~ 27%
Methyl thiazolinyl Soxylat A 25-7 5 ~ 10%
Sunmorl N 60S 5 ~ 10%
GDU-1 type air entrapment agent 1 ~ 5%.
Preferably, each component content is:
Mixed alcohol 27 ~ 29%
Tripoly phosphate sodium STPP 9 ~ 10%
ZK-RJD-1 type mother liquor 23 ~ 25%
Di-alcohol monoisopropanolamine 19 ~ 20%
Methyl thiazolinyl Soxylat A 25-7 9 ~ 10%
Sunmorl N 60S 5 ~ 6%
GDU-1 type air entrapment agent 3 ~ 5%.
Improve the preparation method of cement and concrete adaptive liquid cement grinding additive: water filling in reactor, be heated to 50 ~ 70 DEG C for subsequent use, Sunmorl N 60S is added, stir 15 minutes, add methyl thiazolinyl Soxylat A 25-7, stir 30 minutes, with 100 eye mesh screens filtrations; Add tripoly phosphate sodium STPP, stir 15 minutes; Add GDU-1 type air entrapment agent, stir 10 minutes, with 100 eye mesh screens filtrations; Add again mixed alcohol, ZK-RJD-1 type mother liquor, di-alcohol monoisopropanolamine, stir 20 minutes, with 100 eye mesh screens filtrations, obtain cement grinding aid finished product.
For the present invention, mixed alcohol, ZK-RJD-1 type mother liquor, di-alcohol monoisopropanolamine carry out complete instead of triethanolamine, not only reduce the production cost of cement grinding aid, and three days, 28 days intensity is better than trolamine to make cement, has effectively improved the use properties of cement grinding aid; Use GDU-1 type air entrapment agent effectively to improve the milling capacity of cement mill, save manufacture of cement unit power consumption cost; Use methyl thiazolinyl Soxylat A 25-7 to coordinate Sunmorl N 60S can reduce cement normal consistency water consumption, improve the mobility of cement.
