Enhanced cement grinding aid and preparation method thereof

Abstract

The invention relates to an enhanced cement grinding aid and a preparation method thereof. The enhanced cement grinding aid comprises the following raw materials by mass percent: 5 to 20% of triethanolamine, 5 to 20% of diethanolamine single isopropyl alcohol amine, 20 to 50% of diisopropyl monoethanolamine, 5 to 8% of propylene glycol, 2 to 8% of lignosulfonate, 3 to 10% of sodium lauryl sulfate, 3 to 10% of sodium humate and 10 to 30% of water. The invention further comprises the preparation method of the enhanced cement grinding aid. The prepared enhanced cement grinding aid has the advantages that the strength of cement is improved, the production efficiency is improved, and the cost is lowered.

Description

technical field

[0001] The invention relates to a cement grinding aid and a preparation method thereof, in particular to an enhanced cement grinding aid and a preparation method thereof. Background technique

[0002] Grinding is an important link in the cement production process. With the development of grinding technology, new grinding equipment such as vertical mill and asteroid mill have appeared; however, due to the high manufacturing cost of these equipment and the unknown effect on the performance of finished cement particles, they still cannot be used in cement in the short term. Widely used in production. In the process of converting cement clinker into finished cement, most cement producers still use traditional ball mills for cement grinding. The ball mill was first used in the crushing of ore to reduce the particle size and increase the specific surface area. Although ball mills have been used for quite a long time, the shortcoming of low grinding efficiency of...
