Abstract

The invention discloses a novel liquid cement grinding aid and a preparation method thereof. The novel liquid cement grinding aid is prepared from the following components in parts by weight: 30 to 55parts of paper pulp waste liquid, 10 to 30 parts of triethanolamine, 5 to 25 parts of ethylene glycol, 5 to 20 parts of ammoniom acetate, 15 to 35 parts of urea, 2 to 5 parts of a high-performance water reducer, 2 to 7 parts of unsaturated polyester resin, and 1 to 5 parts of a fluorine surfactant. The novel liquid cement grinding aid prepared in by the method provided bythe invention has good grinding assisting effect, can improve the cement yield in unit time, can reduce the power consumption of the unit yield, and can meet the energy-saving and environmental protection requirements of enterprises.

Description

technical field [0001] The invention relates to the technical field of cement grinding, in particular to a novel liquid cement grinding aid and a preparation method thereof. Background technique [0002] Cement grinding aids can reduce cement production cost, increase cement production efficiency, increase cement output, improve cement performance, quality and improve the operability of cement production process, etc. It has been widely used abroad. China is a big country in cement production, accounting for 60% or more of the world's cement production, and the research and development of cement grinding aids is relatively fast. In the ball milling process of cement production, the friction between materials and between materials and steel balls will make the materials charged with static electricity, making the materials adsorb on the surface of the steel balls, causing ball wrapping, reducing the grinding efficiency, and improving the cement output and quality. Decrease,...
