Abstract
The invention discloses a rare earth and cement activated grinding aid, which solves the problems that the traditional cement grinding aid has poor grinding aid effect and cannot simulate and activate the strength of cement. The rare earth and cement activated grinding aid is characterized by comprising 7-10 percent of rare earth compound, 33-48 percent of inorganic compound, 40-50 percent of organic compound and 5-7 percent of high molecular polymer. The rare earth and cement activated grinding aid is formed by mixing various raw materials which are fine particles with the particle size of 100-200 meshes with water and then compounding. The rear earth and cement activated grinding aid has the advantages that the strength of the cement at each age is improved, the consumption of cement clinker is reduced and the doping amount of a cement mixed material and the quality of the cement are improved. In addition, the rare earth and cement activated grinding aid is suitable for cement production.
Description
Technical field
The invention belongs to the cement grinding technical field, be specifically related to a kind of rare earth activating grinding-aid for cement, the manufacture of cement use that is adapted to improve each age strength of cement, reduces cement clinker consumption, improves the cement admixture incorporation and improve cement quality.
Technical background
For save energy and resource consumption, improve the reasonable utilization ratio of industrial residue, increase the purpose of cement output.The development work development of cement grinding aid is very fast, and cement grinding aid can improve the cement mill unit output, reduces cement clinker consumption, improves the incorporation of cement mixture, improves cement performance and quality etc., is widely used in countries in the world.The effect of grinding aid be in and cement particle surface on electric charge, reduced the static in the grinding machine thus, can make powder be difficult for sticking on the surface of grinding element and liner plate, weaken or eliminate and stick with paste the ball phenomenon, thereby destroy the cushioning effect of material, reduce obstruction or the obturation of the grinding machine that the fine particle in the process of lapping causes, improved the total efficiency of grinding machine.At present, the function singleness of grinding aid, the addition of the cement excitation activator of being developed generally between 5-10%, as Chinese invention patent CN1059411C, Chinese disclosure of the Invention patent CN1220977A; Because add-on is bigger, Financial cost is higher, is difficult to big area and promotes.
Summary of the invention
Purpose of the present invention is exactly for overcoming above deficiency, and the deficiency at existing cement grinding aid exists provides a kind of good grinding-aid effect that not only possesses, contain simultaneously intensify, the activator technology of activated cement intensity, compound rare earth activating grinding-aid for cement.
Main technical schemes of the present invention is as follows:
A kind of rare earth activating grinding-aid for cement, it is characterized in that forming liquid activating grinding-aid for cement by the industrial chemicals of following mass percent is miscible: getting each raw material is the fine particle shape, and granularity is 100 orders-200 orders
Mix the composite composition in back Deng adding entry.
Each raw material total amount of getting is 100 parts, gets 150 parts of water and heats when 80 spend, and starts agitator, adds various raw materials while stirring.At first add mineral compound, rare earth compound, after treating all to dissolve, add organic compound, high molecular polymer successively, after treating all to mix, arrest reaction 30min is finished product after filtration.
Adopt the automatic liquid metering device, the add-on of pressing cement quality per-cent 0.1-0.15% sprays solvent on the cement material or in the bistrique.
Wherein: rare earth compound is made up of a kind of in lanthanum nitrate, the cerous nitrate or two kinds.
Mineral compound is made up of in tripoly phosphate sodium STPP, copper sulfate, the Tai-Ace S 150 one or more.
Organic compound is made up of in diethanolamine, trolamine, the naphthenic acid one or more.
High molecular polymer is a sodium polyacrylate.
A kind of rare earth activating grinding-aid for cement of the present invention has and possesses good grinding-aid effect, contain simultaneously intensify, activated cement intensity is high advantage.
Embodiment
Below in conjunction with embodiment, the present invention is further described:
Embodiment one:
Embodiment two:
Above-mentioned each group is pressed proportion compatibility, and the method for making liquid rare earth activating grinding-aid for cement solvent of the present invention is:
(1) getting each raw material is the fine particle shape, and granularity is 100 orders-200 orders.
(2) getting each raw material total amount is 100 parts, gets 150 parts of water and heats when 80 spend, and starts agitator, adds various raw materials while stirring.At first add mineral compound, rare earth compound, after treating all to dissolve, add organic compound, high molecular polymer successively, after treating all to mix, arrest reaction 30min is finished product after filtration.
(3) (3) adopt the automatic liquid metering device, and the add-on of pressing cement quality per-cent 0.1-0.15% sprays solvent on the cement material or in the bistrique.
(4) the present invention can obviously reduce cement clinker consumption 15-25%, reduces the manufacture of cement cost, improves the utilization ratio of industrial residue, has remarkable economic efficiency and social benefit.
