Abstract

The invention provides a cement grinding aid for enhancing yield increase. The cement grinding aid is prepared from an alcohol amine organic small molecule modified graphene mixed solution, an inorganic early enhancer, an inorganic coagulant, sodium dodecyl sulfate, molasses, mixed diol and deionized water. The alkylol amine organic small molecule modified graphene mixed solution is prepared froman alkylol amine mixture, graphene and deionized water, alkylol amine organic small molecules are a mixture of triethanolamine, diethanolisopropanolamine and triisopropanolamine, and the inorganic early-stage reinforcing agent is a mixture of talcum powder and glass fibers,the inorganic coagulant is borax, wherein the mixed diol is a mixture of ethylene glycol, diethylene glycol and propylene glycol.The synergistic effect of the components can greatly reduce the energy consumption in the powder process, and especially can obviously enhance the machine-hour yield, stimulate the cement strengthand improve the mechanical properties of the cement.

Description

technical field [0001] The invention belongs to the technical field of cement processing, in particular to a cement grinding aid for increasing production. Background technique [0002] Chinese patent application number: 201210265048.6 (publication number CN 102838311 A) discloses a composite cement grinding aid and its preparation method. The cement grinding aid can improve the fluidity of the material in the mill and effectively reduce the over-grinding of the mill. Phenomenon, improve the adhesion of the material to the grinding body, lining board, compartment plate and self-agglomeration phenomenon. However, this technology uses chlorine-containing salts such as sodium chloride and potassium chloride to increase the grinding aid effect. The presence of chloride ions is likely to cause corrosion of steel bars in concrete and affect the service life and durability of concrete. In order to overcome the above-mentioned defects, Chinese patent application number: 20151080287...
