Description
Technical field
The present invention relates to a kind of cement grinding aid, particularly relate to a kind of high efficiency cement composite grinding additive, belong to grinding technology and Chemicals in the manufacture of cement, be suitable for manufacturer and when Working environment when improving cement grinding and cement performance, adopt.
Background technology
In cement pulverizing course, after grog and other material sent into ball mill, can be because the friction that reaches between the material between material and the grinding element produces static with collision, for solving the electrostatic problem of cement mill, the general way that adds cement grinding aid that adopts in the process of lapping generation.And to Research on cement additive and use, domestic as far back as last century the fifties just begin to carry out.At present, the liquid cement grinding additive of selling on the market is composited by pure chemistry materials such as trolamine or industrial waste mostly." with the method for talcum or molasses as cement grinding aid " that for example provides for Chinese invention patent application 92101970.X number, wherein the talcum volume is 0.1～1.0% of a cement clinker, the molasses volume is 0.01～0.1% of a cement clinker weight; Grind silicate cement and adopt the talcum grinding aid, grind slag cement and adopt the molasses grinding aid; The Chinese invention patent application has also provided " a kind of cement grinding aid " for No. 01128350.5, it is made up of the trolamine of by weight 70%-80% and the mother liquor of 20%-30%, and mother liquor is mainly formulated by a certain percentage by alkyl polyglycoside, sodium humate, sulfonated lignin, Sodium dodecylbenzene sulfonate, fatty alcohol-polyoxyethylene ether, poly-phosphate, beta-hydroxy amine, sodium laurylsulfonate, senior alkyl ether sodium sulfate salt, dimethylbenzene naphthalenesulfonate, sodium laurylsulfate, white sugar and water.Existing aforesaid liquid cement grinding aid makes the grinding aid cost up because raw material is difficult for obtaining, and cement dust is flown upward seriously, and grinding-aid effect is not obvious or influential to the performance of cement.
Summary of the invention
The objective of the invention is to overcome the prior art above shortcomings, improve by research, provide a kind of novel high efficiency cement composite grinding additive, this kind grinding aid is small molecular weight polyvalent alcohol, a small amount of trolamine, spent pulping liquor and mineral sulfates is compound and with lower molecular weight soap reinforcement disperse water cement grinding aids, can improve cement grinding shopwork environment after the use, have and significantly to reduce cost, reduce the characteristics that dust from flying also effectively improves cement performance.
The technical solution that the present invention provides is: this high efficiency cement composite grinding additive, main ingredient includes trolamine and acetate, its characteristics are also to include alum liquor, spent pulping liquor, lower molecular weight soap and water, and wherein the add-on of each component is: (mass percent)
Trolamine 5～20%
Acetate 10～30%
Alum liquor 10～30%
Spent pulping liquor 10～30%
Lower molecular weight fat
Fat hydrochlorate 0.5～5%
Water 5～20%.
The preparation technology of this high efficiency cement composite grinding additive that the present invention provides is:
Earlier be that 5～20% trolamine at room temperature joins in 5～20% the water with mass percent, after middling speed stirs, be that 10～30 acetate and mass percent are that 10～30% alum liquor adds and fully mixes again with mass percent, progressively add 10～30% spent pulping liquor in the above-mentioned mixed solution again and mix, add mass percent at last and be 0.5～5% lower molecular weight soap and mix after leave standstill, the filtrate that leaches behind the throw out is finished product.The present invention is a brown liquid, and proportion is 1.10～1.20 grams per milliliters.
Compared with prior art, the beneficial effect of this high efficiency cement composite grinding additive that the present invention provides is: can reduce product cost significantly, grinding-aid effect is more remarkable, improve Working environment, and can obviously improve the performance of cement, and production technique is simple, and product can standing storage.
