Abstract
The invention relates to a liquid cement grinding aid which can obviously reduce the dosage of trolamine and does not contain urea. The grinding aid comprises the following compositions in weight percentage: 1 to 10 percent of trolamine, 5 to 10 percent of diglycol, 1 to 10 percent of trimeric sodium phosphate, 10 to 30 percent of molasses, 0 to 20 percent of sodium thiosulfate, 0 to 10 percent of air entraining component and the balance being water, wherein the air entraining compositions are triterpenoid saponin air entraining agent, sodium lignin sulfonate or a mixture of the triterpenoid saponin air entraining agent and the sodium lignin sulfonate at any proportion. The invention obviously reduces the dosage of the trolamine, does not contain the urea, lowers product cost and simultaneously facilitates the environmental protection. The sodium thiosulfate has the function of exciting mixed materials of cement and can improve the initial strength and the later strength of the cement, thereby effectively improving the service performance of the cement grinding aid. The triterpenoid saponin air entraining agent and the sodium lignin sulfonate have the action of the auxiliary aided grinding and simultaneously properly entrain air to reduce the water consumption of the cement standard consistence.
Description
Technical field
The present invention relates to a kind of cement grinding aid, is a kind of liquid cement grinding additive specifically.
Background technology
Domestic water cement grinding aids product has powder and two kinds of forms of liquid at present.Because liquid product is easy to use, cement factory only need increase a storage tank and a microprocessor pump drive, just can add smoothly, does not need complicated heavy equipment, is therefore used widely gradually.Liquid cement grinding additive; Its prescription can basic fixed; Need be in order not adapt to the often needs change of cement and changes of seasons prescription as the concrete admixture product, it mainly is single or combination products such as amine, terepthaloyl moietie, acetate that the prescription of existing liquid cement grinding additive is formed.Because these products, it is few to have a volume, and liquid meter adds convenient, improves mill grinding efficiency 10～20%, saves the unit time power consumption, improves the flowability of cement powder, helps bulk shipment and storage, so the cement factory use is very general abroad.
Domestic a kind of typical liquid cement grinding additive, it is made up of trolamine, terepthaloyl moietie, Ammoniom-Acetate, urea, alkyl polyglycoside, sodium humate, AEO and spent pulping liquor.External a kind of typical liquid grinding aid patent, it is by trolamine, terepthaloyl moietie, sodium-acetate, urea, hydroxyalkyl amine, N, compositions such as two (2-hydroxyethyl)-N-(2 hydroxypropyl) amine, three (the 2-hydroxyl butyl) amine of N-, xylogen.This type prescription all has some weakness, as: main raw material(s) trolamine price is high always, causes the liquid grinding aid product cost higher; Alkali behind urea and the hydrated cementitious reacts, and can emit ammonia, and is unfavorable to the covil construction living environment; The exciting agent that does not add the excited cement mixture activity to improve the early stage and later strength of cement, increases blending amount of mixture material, helps the energy-saving and emission-reduction of Cement industry.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of liquid cement grinding additive, and this liquid cement grinding additive can reduce the consumption of trolamine significantly, does not contain urea.
Liquid cement grinding additive according to the invention; Contain trolamine, glycol ether, tripoly phosphate sodium STPP, molasses, Sulfothiorine, bleed component and water; The mass percent of each component is trolamine 1-10%, glycol ether 5-10%, tripoly phosphate sodium STPP 1-10%, molasses 10-30%, Sulfothiorine 0-20%, bleed component 0～10%; Surplus is a water, and wherein bleed component is the mixture of triterpenoid saponin air entrapment agent, sodium lignosulfonate or their arbitrary proportion.Wherein molasses are liquid, have commercially available.The present invention makes full use of the trade waste molasses and tripoly phosphate sodium STPP is done grinding aid, has significantly reduced the consumption of trolamine, and does not contain urea, has reduced product cost, helps environmental protection simultaneously.
As preferred version of the present invention, said liquid cement grinding additive contains the Sulfothiorine of 10-20%.Sulfothiorine has the effect of excited cement blended material, and favourable for the early stage and later strength that improves cement, it is good to the flexibility of concrete admixture simultaneously, is the ideal strongthener, thereby can effectively improves the use properties of cement grinding aid.
As another kind of preferred version of the present invention, the bleed component in the said liquid cement grinding additive is 1～5% triterpenoid saponin air entrapment agent and 1～5% sodium lignosulfonate.Simultaneously suitable bleed reduces cement normal consistency water consumption thereby triterpenoid saponin air entrapment agent and sodium lignosulfonate play auxiliary grinding aid effect.Triterpenoid saponin air entrapment agent and sodium lignosulfonate are commercially available product.
Aforesaid liquid cement grinding aid of the present invention adopts common process to mix and can obtain, and repeats no more at this.
This product is the liquid of homogeneous, and product is easy to use, and cement factory only need increase a storage tank and a microprocessor pump drive, just can add smoothly, does not need complicated heavy equipment.This product appearance is a brown liquid, PH (10% concentration)=8.5～12.0, proportion (20 ℃): 1.10～1.28g/cm
3, viscosity is 30～100cps (centipoise).Be applicable to ordinary Portland cement, pulverized fuel ash cement and composite Portland cement, volume is 0.02%～0.06%.Volume is few, does not change Cement Production technology, and metering is convenient.
