Description
Technical field
The present invention relates to composite enhanced cement grinding aid of a kind of liquid state and preparation method thereof.
Background technology
According to statistics, in Cement industry, the energy that grinding process consumes about 97% becomes heat energy and wastes, and only has seldom part energy for increasing the specific surface area of material.Therefore, energy-saving and cost-reducing is the urgent task of current cement production enterprise, and compares with the approach of other energy-saving and emission-reduction in the cement production process, and using cement grinding aid to improve mill efficiency is the most direct effective means.In grinding process, add a small amount of cement grinding aid, can consume under the identical condition with mill power in the fineness of cement and increase output, also can consume the specific surface area that increases cement under the identical condition with mill power at cement output, thereby improve intensity and the quality of cement.Therefore, adopting cement grinding aid is the effective measure that improve cement grinding efficient, reduce unit power consumption, and very large technical economic benefit is arranged.
Yet liquid cement grinding additive of the prior art is composited with the pure chemistry compositions such as trolamine or industrial waste.Existing grinding aid Performance Ratio is more single, to improve mill output or to increase strength of cement as main, can not be the more cost of cement production enterprise saving merely.
Summary of the invention
The object of the present invention is to provide composite enhanced cement grinding aid of a kind of liquid state and preparation method thereof, the grinding aid and the concrete admixture that are prepared by the method have good adaptability, and concrete use properties and weather resistance are had no adverse effects.
For reaching above-mentioned purpose, solution of the present invention is:
The composite enhanced cement grinding aid of a kind of liquid state, formulated by weight by following batching: enhancement component 5-15 part, grinding aid component 20-40 part, siliceous compound 0.1-1 part is stablized component 10-50 part, and all the other are water.
The preparation method of the composite enhanced cement grinding aid of a kind of liquid state may further comprise the steps:
Step 1, in reactor, injected water is heated to 50-60 ℃;
Step 2 adds enhancement component and siliceous compound successively, stirs 30 minutes;
Step 3 adds and stablizes component and grinding aid component, stirs 10 minutes;
Step 4, regulator solution pH value stirred 10 minutes to 8-9, namely got liquid composite enhanced cement grinding aid.
Further, enhancement component is one or more in Sulfothiorine, urea, water glass, sodium-acetate, tripoly phosphate sodium STPP, Sodium hexametaphosphate 99, Sunmorl N 60S, the sodium aluminate, is used for the activity of excited cement adulterant, improves strength of cement.
Further, the grinding aid component is one or more in Monoethanolamine MEA BASF, diethanolamine, trolamine, tri-isopropanolamine, ethylene glycol, glycerol, glycol ether, Diethylene Glycol, di-alcohol α-amino isopropyl alcohol, molasses, the tetrahydroxy ethyl hexyl diamines, be used for eliminating the electrostatic effect of cement clinker and adulterant thereof, improve mill efficiency, optimize cement size grading and distribute.
Further, siliceous compound is block silicone oil, improves the intensity of cement, has obvious excitation.
Further, stable component is one or more in sulfonated lignin, sulfamate, the sulfonated acetone formaldehyde condensation products, improves the adaptability of cement grinding aid and concrete admixture, improves the over-all properties of cement.
After adopting such scheme, the liquid composite enhanced cement grinding aid of the present invention's preparation compared with prior art has the following advantages:
One, the cement grinding aid product does not relate to villaumite, has guaranteed that concrete has good weather resistance.
Two, add enhancement component in the cement grinding aid product, it is obvious to ordinary Portland cement and composite Portland cement enhancement, can when to mix industrial solid castoff be main blended material more, guarantee to improve more than the cement 28d ultimate compression strength 3MPa.
Three, add in the cement grinding aid product and stablize component, greatly improved cement physical properties and mechanical property.
Four, the present invention fills a prescription simple and technological operation is simplified, and the grinding aid grinding aid reinforced effects of production is good.
