Abstract

The invention provides an efficient cement grinding aid as well as a preparation method and application thereof. The efficient cement grinding aid comprises diethanolisopropanolamine, calcium lignosulphonate and polyacrylamide. The invention also provides a preparation method of the efficient cement grinding aid. According to the efficient cement grinding aid provided by the invention, the friction coefficient of powder can be reduced in the cement material grinding process, and the fluidity of cement powder is accelerated, so that the powder is fully ground, the grading of grinding particles is improved, the content of micro-powder particles is increased, the grinding efficiency is improved, and the power consumption of a grinding machine is reduced; and the water retention effect of the cement in the using process can be improved, and the adaptability of the cement can be improved.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a high-efficiency cement grinding aid and its preparation method and application. Background technique [0002] Cement grinding is a necessary process and key link in cement production. Its energy consumption and electricity consumption account for 30% of the total energy consumption of cement production and more than 70% of the total electricity consumption. In order to reduce the production cost of cement and improve the quality of cement and production efficiency, the most direct and effective way is to add a small amount of cement grinding aids in the cement grinding process, which can increase output, reduce labor force, and increase production capacity without increasing grinding water and changing grinding time. Reduce the power consumption per unit capacity of cement and reduce production costs. [0003] At present, there are more and more studies on improving the formu...
