Abstract
The invention relates to a preparation method of a cement grinding aid, and the preparation method comprises the following steps: mixing tri-isopropanolamine with water in the mass ratio of 1:3 to 1:5, heating to 40 to 50 DEG C, until the tri-isopropanolamine is completely dissolved, to obtain an A solution; adding silica fume to dodecylbenzene, stirring to fully dissolve to obtain a B solution for standby use, wherein the silica fume and the adodecylbenzene mixed according to the mass ratio of 1:1 to 1:4.5; under the stirring condition, according to the mass ratio of 1:0.25:0.5:0.25:0.25:0.25-1:0.5:1:0.5:0.5:0.5, successively adding sodium acetate, the B solution, sugar ether, ethylene glycol, triethanolamine to the A solution to obtain the cement grinding aid. The preparation method has the advantages of simple process and low cost, and the prepared cement grinding aid is stable in quality, and has a good improving effect on cement performances.
Description
Technical field
The present invention relates to field of cement production, particularly relate to a kind of cement grinding aid preparation method.。
Background technology
In manufacture of cement, grinding process is the link that energy consumption is the highest, and capacity usage ratio is extremely low again, only has a little part to be used to increase the specific surface area of material.In grinding process, add a small amount of chemical additive-grinding aid, can mill efficiency be significantly improved, reduce energy consumption.Cement grinding aid is made up of one or more surfactants, and the effect of most of cement grinding aid shows that cement grinding aid has reduction cement granularity, increasing specific surface area, improves some physical and chemical performance of cement, reduces the effects such as grinding pow consumption.Lot of domestic and international factory and research institution are all carrying out the research work about cement grinding aid, Novel aid grinding agent product constantly occurs, increasing tensio-active agent is used to produce cement grinding aid, thus the grinding aid product be suitable for for exploitation is efficient provides new approaches.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cement grinding aid preparation method.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of cement grinding aid preparation method, comprises the steps:
Be that 1:3 ~ 1:5 mix with water according to mass ratio by tri-isopropanolamine, be heated to 40 ~ 50 DEG C and obtain solution A until tri-isopropanolamine all dissolves;
Join in dodecylbenzene by silicon ash, stir and make it fully dissolve to obtain B solution stand-by, wherein silicon ash is that 1:1 ~ 1:4.5 mixes with dodecylbenzene according to mass ratio;
Under agitation, be that 1:0.25:0.5:0.25:0.25:0.25 ~ 1:0.5:1:0.5:0.5:0.5 adds sodium-acetate successively in solution A, B solution, sugar ether, ethylene glycol, trolamine obtain described cement grinding aid according to mass ratio.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described three Virahols, silicon ash, dodecylbenzene, sodium-acetate, sugar ether, ethylene glycol, trolamine are commercially available technical grade.
Described sugar ether is mainly used in toning or improves cement setting time.
The invention has the beneficial effects as follows: preparation method's technique of the present invention is simple, and with low cost, gained cement grinding aid steady quality, has better improvement result to the performance of cement.
