Abstract

A cement composite grinding aid mainly comprises trolamine and is characterized by also comprising alkyl polyglycoside, sodium humate, lignosulphonate, sulphite liquor, fatty acid salt with low molecular weight, polyphosphate, benzoylate trisodium and water. The invention can reduce the cost of the product, has obvious grinding aid effect, improves working environment, and has simple production technique, and the products can be stored for a long time.

Description

A kind of cement composite grinding additive
Technical field
The present invention relates to a kind of cement grinding aid, particularly relate to a kind of cement composite grinding additive, belong to grinding technology and Chemicals in the manufacture of cement.
Background technology
For solving the electrostatic problem that cement mill produces at process of lapping, the general way that adds cement grinding aid that adopts.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.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 cement composite grinding additive, this kind grinding aid is that trolamine, spent pulping liquor and mineral sulfates are compound and strengthen the disperse water cement grinding aids with lower molecular weight soap, 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 cement composite grinding additive, main ingredient includes trolamine, its characteristics are also to include alkyl polyglycoside, sodium humate, sulfonated lignin, spent pulping liquor, lower molecular weight soap, poly-phosphate, benzene first trisodium and water, and wherein the add-on of each component is:
Trolamine 30～50%, alkyl polyglycoside 5～15%
Sodium humate 5～15%, sulfonated lignin 5～15%,
Spent pulping liquor 10～20%, lower molecular weight soap 0.5～5%
Poly-phosphate 0.1～1%, benzene first trisodium 1～3%, water 5～20%
The preparation technology of this 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 5～15% alkyl polyglycoside again with mass percent, mass percent is 5～15% sodium humate, mass percent is 5～15% lignosulfonic acid salts solution, mass percent is that 0.1～1% poly-phosphate and mass percent are that 1～3% benzene first trisodium adds and fully mixes, progressively add 10～20% 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.
Compared with prior art, the beneficial effect of this cement composite grinding additive that the present invention provides is: can reduce product cost, grinding-aid effect is remarkable, improves Working environment, and production technique is simple, and product can standing storage.
Embodiment
Embodiment:
Earlier be that 35% trolamine at room temperature joins in 15% the water with mass percent, after middling speed stirs, be 8% alkyl polyglycoside again with mass percent, mass percent is 10% sodium humate, mass percent is 6% lignosulfonic acid salts solution, mass percent is that 0.5% poly-phosphate and mass percent are that 2% benzene first trisodium adds and fully mixes, progressively add 20% spent pulping liquor in the above-mentioned mixed solution again and mix, add mass percent at last and be 2% lower molecular weight soap and mix after leave standstill, the filtrate that leaches behind the throw out is finished product.
