Abstract
The invention provides a cement grinding aid, and relates to the field of cement production technology. The cement grinding aid comprises components by mass percent: 55-65% of water, 10-12% of sodium nitrite, 8-10% of industrial salt, 3-5% of calcium lignosulphonate, 3-5% of sodium acetate, 5-8% of triethanolamine and 3-5% of glycol. After the cement grinding aid is adopted, the quality and the performances of cement are improved while the power consumption is saved; the performances of the cement reach the level of the performances of foreign similar products, and the cost and the price of the cement are lower than those of the foreign similar products; and the dosage of cement clinker is reduced, and the cement strength can be improved.
Description
Technical field:
The present invention relates to the technology of producing cement field, relate in particular to a kind of cement grinding aid.
Background technology:
From twentieth century thirties, British Goddard with resin as grinding aid and obtain patent.People have successively tested grinding aids such as acetic acid, phosphoric acid salt, sulfonated lignin, terepthaloyl moietie, phenol, trolamine, tung oil and pitch again subsequently.To the sixties; Industrially developed country is like Japan, the U.S., Germany, the FSU, to the research of grinding aid with use more and more widely, all uses grinding aid in the cement mill that some developed countries are nearly all; The China that compares starts late to the research and the utilization of grinding aid; The later stage fifties, have only the minority cement mill to test with coal, spent pulping liquor, soap waste liquid, effect is very unobvious; At present, the cement grinding aid of domestic research and application has liquid grinding aid and solid grinding aid, and its basal component mostly belongs to organic surface-active substance.Be mainly: amine, alcohols, alcamines, lignosulfonic acid salt, lipid acid and its esters, alkyl sulfonates etc.Concrete material is: trolamine, Diethylene Glycol, terepthaloyl moietie, sulfonated lignin, formic acid, Triple Pressed Stearic Acid, oleic acid, X 2073 etc.
Domestic most employing technical pure polymerization organic salt and inorganic salt are the staple of grinding aid, and cost is higher, technico-economical comparison incompatibility practical condition, and the product adaptation face is narrower, does not also have suitable product for the higher material of temperature especially.Even in different manufacturers, also have the bigger situation of difference on effect for the product application of the same race of different manufacturers.Currently available products can't be given full play to this product and improve the grinding material adhesiving effect, and fails with multiple effective grinding aid components matching together, thereby brings into play best grinding effect, and chlorine or alkali in the existing simultaneously grinding aid can bring harm to cement or concrete.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defective of prior art, provides a kind of and can reduce the powder surface free energy, can generally be suitable for again, can improve the cement grinding aid of powder granule distribution and pattern.
Technical problem to be solved by this invention adopts following technical scheme to realize.
A kind of cement grinding aid is characterized in that, this grinding aid comprises the mass fraction of following component and each component:
This grinding aid comprises the preferred mass umber of following component and each component:
Cement grinding aid provided by the invention is when accomplishing to save power consumption; Improve the quality and the performance of cement, on performance, reach the level of external like product, on cost, price, be lower than the level of external like product; Reduce the consumption of cement clinker, improve strength of cement.
Embodiment:
For technique means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment one
A kind of cement agent prescription:
Embodiment two
A kind of cement agent prescription:
More than show and described ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification sheets just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
1. a cement grinding aid is characterized in that, this grinding aid comprises the mass fraction of following component and each component:
2. cement grinding aid according to claim 1 is characterized in that, this grinding aid comprises the preferred mass umber of following component and each component:
