Abstract

The invention provides an efficient accelerator for cement production and a processing method. The preparation method comprises the following steps: soaking olive peel residues with an ethanol solution, filtering to obtain a filtrate and a filter residue, and freeze-concentrating the filtrate to obtain a concentrated filtrate; adding a mixed waste acid into oxidized lotus seed starch, heating, andadding other raw materials to prepare a starch graft polymer; respectively drying soybean dregs and the filter residue, mixing and grinding; mixing an obtained ground product with the starch graft polymer, adding distilled water, and heating to obtain a reaction mixed solution; cooling, carrying out enzymolysis and fermentation on the reaction mixed solution to obtain a fermentation solution, mixing the fermentation solution with vinyltriethylsilane, and heating to obtain a prefabricated solution; mixing the prefabricated liquid, a polyhydric alcohol and sodium lignin sulfonate, adjusting thepH value, sequentially adding an organic alcohol amine compound, ethylene glycol, water and the concentrated filtrate while stirring, and finally continuously stirring for 20-40 minutes. According tothe preparation method, the cement production efficient accelerant with better grinding aid enhancement performance is prepared at lower cost.

Description

technical field [0001] The invention relates to the field of production of cement auxiliary material preparations, in particular to a high-efficiency accelerator for cement production and a processing method. Background technique [0002] In cement production, the grinding process is the link with the highest energy consumption, and the energy utilization rate is extremely low, and only a small part is used to increase the specific surface area of ​​the material. Adding a small amount of chemical additives—grinding aids during the grinding process can significantly improve the grinding efficiency and reduce energy consumption. Cement grinding aids are composed of one or several surface active substances. The application effect of most cement grinding aids shows that cement grinding aids can reduce cement particle size, increase specific surface area, improve some physical and chemical properties of cement, and reduce grinding. power consumption etc. [0003] Cement grindin...
