Problems solved by technology

[0002] At present, in cement production, when the liquid cement grinding aid is used to make cement, the grinding efficiency of the mill is low, and the strength of the cement is low.
Some currently used grinding aids contain chloride ions, sulfate ions, ammonium ions, and phosphate ions. Due to the existence of these ions, they affect the characteristics of cement, corrode the metal in the building, and affect the building. durability

Abstract

The invention relates to a liquid cement grinding aid capable of increasing the grinding efficiency of a cement mill and enhancing cement strength. The liquid cement grinding aid is prepared from the following components in percentage by weight: 10-20 percent of triethanolamine, 5-10 percent of tri-isopropanolamine, 2-5 percent of diethylene glycol, 2-5 percent of sodium formate, 2-5 percent of sodium acetate, 1-3 percent of sodium lignosulphonate and the balance of water.

Description

technical field [0001] The invention relates to a grinding aid, in particular to a liquid cement grinding aid. Background technique [0002] At present, in cement production, when the liquid cement grinding aid is used to manufacture cement, the grinding efficiency of the mill is low, and the strength of the cement is low. Some currently used grinding aids contain chloride ions, sulfate ions, ammonium ions, and phosphate ions. Due to the existence of these ions, they affect the characteristics of cement, corrode the metal in the building, and affect the building. durability. Contents of the invention [0003] The object of the present invention is to provide a liquid cement grinding aid capable of improving the mill grinding efficiency of cement and enhancing the strength of cement. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a liquid cement grinding aid, characterized in that: by triethanolamine, triisopropa...
