Abstract
The invention discloses a chloride-free cement grinding aid, and belongs to the technical field of chemical additives. The chloride-free cement grinding aid contains the following ingredients in percentage by mass: 5-8% of reinforcing agent, 39-65% of grinding aid and 30-56% of water. A method for preparing the chloride-free cement grinding aid comprises the following steps: proportionally putting the reinforcing agent and the grinding aid into a reactor, mixing uniformly, then, adding the water, and continuously stirring until the mixture is uniform. The chloride-free cement grinding aid has the beneficial effects that the compressive strength of cement at the time of 3 days and 28 days is improved, the yield of the cement is increased, and the chloride-free cement grinding aid does not contain chloride ions and is harmless to buildings and human bodies.
Description
Technical field
The present invention relates to a kind ofly without chlorine water cement grinding aids, belong to chemical additive technical field.
Background technology
Cement production enterprise is the Liang Gao enterprise of typical high pollution high energy consumption, pursuing under the megatrend of Green GDP, society and enterprise are all in the urgent need to energy-saving and emission-reduction, cement grinding aid is as a kind of innovative application technology, can improve manufacture of cement efficiency, reduce energy consumption, improve cement quality, reduce the ratio of mixing of conveying, this has found a breach for cement production enterprise energy-saving and emission-reduction.The cement grinding aid of current domestic use is divided into two kinds of liquid and powders, and single to the action effect of cement.That is, pretend with not obvious after early strength function, the early strength function of pretending use after having is not obvious, and currently available products contains the chlorion that building iron is had to corrosive nature, so greatly affect economic benefit and the social benefit of cement production enterprise.
Summary of the invention
The object of the invention is in order to make up the deficiencies in the prior art, provide a kind of have concurrently early strength function and after pretend use, and the cement grinding aid of chloride ion-containing does not solve the problems referred to above.
A chlorine water cement grinding aids, comprises following component by mass percentage:
Toughener: 5-8%;
Grinding aid: 39-65%;
Water: 30-56%.
In the present invention, described toughener is one or more in acetic acid, sodium acetate, amine acetate.
In the present invention, described grinding aid is one or more in diethanolamine, trolamine, glycol ether, tri-isopropanolamine.
In the present invention, the concentration of described trolamine is 75-99%, and the concentration of described glycol ether is 80-99%, and the concentration of described tri-isopropanolamine is 85-90%.
In the present invention, described grinding aid is the mixture that trolamine, glycol ether and tri-isopropanolamine form for 6-10:3-5:30-50 in mass ratio.
The preparation method of cement grinding aid of the present invention comprises the steps: in reactor, adds in proportion grinding aid and toughener, after mixing, adds water, stirs.
The invention has the beneficial effects as follows: improved 3 days and the ultimate compression strength of 28 days of cement, also improved the output of cement, chloride ion-containing not, to building and body harmless.
