Description
Technical field
The present invention relates to building material technical field, particularly relate to a kind of grinding aid for cement and preparation method.
Background technology
Cement grinding is one important procedure in manufacture of cement, and it is by clinker and retarder by mechanical means
With the material grinding such as performance adjustment material to suitable granularity, to meet cement slurry and condense, hardening requirement.In powder-grinding process
In, material particles is progressively refined by equipment fine grinding, and specific surface area increases, and its surface is charged because of chemical bond rupture, grain
Son mutually absorption can form caking or sticky on abrasive body and liner plate, makes mill efficiency decline, adds the consumption of the energy.
Research shows, adds chemical agent and can improve process of lapping, improve grinding efficiency or capacity usage ratio in process of lapping, this
Class chemical agent is called grinding aid.
China was once utilizing spent pulping liquor, coal etc. to make grinding aid at the beginning of the 50's of 20th century, 20 century 70s, Bu Shaoqi
Industry and R&D institution have extensively carried out the research work about grinding aid.20th century the mid-80, building materials institute and Tianjin of country
First lightization be proposed N series and S series cement grinding aid.During material is by grinding, when grain diameter is reduced to
After micron order, quality is in uniformly, defect reduces, intensity and hardness increase, and grindability deteriorates；Meanwhile, because of specific surface area and table
Face can significantly increase, and subparticle mutual conglomeration aggregation tendency is remarkably reinforced.If not taking certain technological measure, Jiu Huiyin
Play mill efficiency decline, per unit area yield power consumption by significantly raised.After especially China implements cement new-standard, intensity index and fineness are wanted
Asking and all increase, this just makes grinding aid more cause the concern of vast cement production enterprise.
According to final form, grinding aid can be divided into；Solid, liquids and gases grinding aid.Solid grinding aid has: stearic acid
Salt, silica sol, aquadag, white carbon black, flyash, Gypsum Fibrosum etc.；Liquid helps mushroom agent to have: organosilicon, triethanolamine, second
Glycol, propylene glycol, polyacrylate, polycarboxylate etc.；Gas grinding aid has: the polar substances of vaporous and nonpolar property thing
Matter etc..Can be divided three classes by chemical constitution grinding aid: polymer-inorganic salt, polymerization organic salt and complex chemical compound.Domestic mostly
Using technical pure polymerization organic salt and inorganic salt is the main component of grinding aid, relatively costly, and technical-economic index is inadaptable real
The border condition of production, product adaptation face is narrower.

The performance study of a kind of grinding aid for cement of test example gained of the present invention (embodiment 5):
1, test raw material and method
Raw material: grog and Gypsum Fibrosum (purchasing in Xing Baixing commerce and trade at sunshine company limited)；A kind of helping for cement of gained of the present invention
Grinding agent A；Cement grinding aid B(purchases in Laiwu film new material company limited).
This test is divided into three groups, experimental group, matched group and blank group.Its proportioning is grog: Gypsum Fibrosum=95:5.By ripe
Material and Gypsum Fibrosum are broken for the material of 0.5-3mm, mixing respectively, are added by grinding aid in material, and wherein experimental group adds the present invention
Gained grinding aid A(addition content is 0.02%), it is 0.04% that matched group adds grinding aid B(addition content), blank group is not spiked with grinding aid
Agent；By the grinding 30min in test grinding machine of the material after admixture grinding aid, after grinding, after 0.08mm sieve crossed by material, respectively
Carry out mensuration and the cement performance test of powder characteristics.Wherein test the distribution of its particle diameter with LS-C (I) type laser particle analyzer.
Result is as shown in table 1.Specific area measuring test basis GBT8074-2008 is measured, and uses angle of repose contour injection method to survey
Fixed, strength of cement mortar is measured according to GBT17671-1999.Result is as shown in table 2.
2, result of the test and analysis
Table 1 cement powder particle size distribution
Substantially diminish, wherein from the data in table 1, it can be seen that filled the most blank group of cement powder mean particle size after grinding aid
Experimental group mean particle size is significantly less than matched group, makes the mean diameter of cement be reduced to 18.1 μm by 26.9 μm, it is seen that to help
Mill effect is fairly obvious；The 3-30 μm particle diameter in experimental group played a major role cement character, content is notable compared with matched group
Increase, improve 18.1%, be indicated above the grinding that a kind of grinding aid for cement of gained of the present invention significantly improves cement thin
Degree, improves the distribution of particles of cement.
The impact of the different Grinding Aids On Cement Properties of table 2
From the data in table 2, it can be seen that the cement specific surface area adding grinding aid all increases relative to the cement not filling grinding aid；
Experimental group and matched group cement screen over-size are below blank group, and experimental group screen over-size reduces by 38.7% than matched group；Show this
Bright gained grinding aid significantly reduces coarse grained content compared with matched group, hence it is evident that improve cement fineness effect；Angle of repose is used for
Weigh and evaluate the mobility of powder body.Knowable to table 2 data, compared with blank group that is not added with grinding aid, after adding grinding aid
Experimental group and matched group reduce 7.1 ° and 3.2 ° angle of repose respectively, and experimental group is significantly greater than matched group more by a small margin.Thus
Visible, gained cement grinding aid of the present invention makes the mobility of cement be significantly improved, and changed dramatically between powder granule
Contact angle and decrease frictional resistance.Cement is improve the most to some extent from intensity data, experimental group and matched group
Early, later stage anti-folding/comprcssive strength, and experimental group is substantially better than matched group improving in strength of cement, and its reinforced effects ten is clearly demarcated
Aobvious.
It should be pointed out that, the detailed description of the invention more representational example that is the present invention, it is clear that the skill of the present invention
Art scheme is not limited to above-described embodiment, it is also possible to have many variations.Those of ordinary skill in the art, the most public with present invention institute
What what that open or according to file written description was undoubted obtained, all it is considered as this patent scope of the claimed.
