Abstract
A grinding aid for cement contains triethyanolamine (70-80 wt.%) and the mother liquid (20-30 wt.%) which is prepared from 13 raw material including alkylpolyglycoside, sodium humate, lignosulfonate, sodium dodecylphenylsulfonate, polyoxyethylenated alcohol, polyphosphate, etc. It can be used to increase cement output and strength, improve cement performance and decrease productive cost.
Description
Technical field
The invention belongs to the cement manufacturing technology, is composition and the content that discloses a kind of cement grinding aid specifically.
Background technology
In the process of making cement, behind grog, additional materials and the gypsum mixtures feeding grinding machine of cement, in the process of grinding, because violent, frequent, complicated friction and bump between material and the material, between material and the grinding element, make material produce static, these materials that have electric charge can be adsorbed on the surface of steel ball and grinding element, cause cement mill serious bag ball, bag forging phenomenon to occur; When the humidity of the additional materials that feeds is higher than 5%, can in grinding machine, produce a large amount of water vapour again, the humidity of abrasive is increased, can produce above-mentioned bag ball, bag forging phenomenon equally, cement output and quality are descended significantly.For solving the electrostatic problem that cement mill produces at process of lapping, abroad some enterprises have taked external electricity to eliminate static, but effect is not so good.Have yet and adopt cement grinding aid, as the Xi Pu company of selling the U.S. in the market, the cement grinding aid that Luoyang, Henan Wan Shun company produces, though can improve the output of cement, its quality is not improved.
Technology contents
The purpose of this invention is to provide a kind of output that can improve cement, can improve the cement grinding aid of cement quality again.
The present invention is made up of the trolamine of by weight 70%-80% and the mother liquor of 20-30%, and described mother liquor per kilogram component and content are: alkyl polyglycoside 7-20 gram, sodium humate 17-53 gram, sulfonated lignin 4-10 gram, Sodium dodecylbenzene sulfonate 2-22 gram, fatty alcohol-polyoxyethylene ether 10-30, poly-phosphate 1-9 gram, beta-hydroxy amine 7-2 gram, sodium laurylsulfonate 1-14 gram, senior alkyl ether sodium sulfate salt 2-13 gram, dimethylbenzene naphthalenesulfonate 4-10 gram, sodium laurylsulfate 3-30 gram, white sugar 3-8 gram, all the other are water.
Being used for mother liquor per kilogram component of the present invention and content preferred value is: alkyl polyglycoside 5 grams, sodium humate 24 grams, sulfonated lignin 7 grams, Sodium dodecylbenzene sulfonate 13, fatty alcohol-polyoxyethylene ether 21 grams, poly-phosphate 1.8 grams, beta-hydroxy amine 12 grams, sodium laurylsulfonate 4.6 grams, senior alkyl ether sodium sulfate salt 10 grams, dimethylbenzene naphthalenesulfonate 9.4 grams, sodium laurylsulfate 8.4 grams, white sugar 5 grams, all the other are water.
Mother liquor of the present invention should prepare before use in advance, comprises the steps:
(1) with 20 °～30 ℃ water injection reactor, adds alkyl polyglycoside, fatty alcohol-polyoxyethylene ether then, stirring reaction;
(2) senior alkyl ether sodium sulfate salt, sodium laurylsulfate, Sodium dodecylbenzene sulfonate, poly-phosphate, beta-hydroxy amine, sodium laurylsulfonate are added in the aforesaid reaction vessel stirring reaction;
(3) sulfonated lignin, dimethylbenzene naphthalenesulfonate are added in the aforesaid reaction vessel stirring reaction;
(4) sodium humate, white sugar are added stirring reaction in the aforesaid reaction vessel.
Final mother liquor, but long-term storage.
Superior part of the present invention is:
(1) in grinding the process of cement, add this grinding aid after, can improve the unit-hour output of cement, thereby reduce power consumption;
(2) compare with similar cement grinding aid, addition per ton is little, and effect of increasing production is obvious;
(3) add this grinding aid after, the water consumption of system grout does not increase on the contrary sometimes and reduces, and can prolong cement setting time, but denseness is constant, its result is specially adapted to transmit cement with travelling belt, promptly large-scale cement is irrigated;
(4) use the quality of the cement of this grinding aid to be greatly improved, its compressive strength rate of 28 days does not add increase by the 2～5MPa of grinding aid;
(5) owing to use this grinding aid, the label of cement improves, thereby can add in cement into some additional materials, thereby the cost of producing cement is reduced.
