raw materials for cement grinding aids TIPA

It is an important raw material for cement grinding aids. Which can improve the grinding efficiency, enhance the both early and late strength.       

The invention belongs to the chemical field and particularly relates to a cement grinding aid. The cement grinding aid comprises polyether polyol which is polypropylene oxide ethylene oxide ether with molecular weight of 200-400, and the ethylene oxide accounts for 10-90%. The cement grinding aid is prepared from the following raw materials in parts by weight: 1 part of polyether polyol, 1-1.2 parts of auxiliaries and 7-9 parts of water, wherein the auxiliaries are obtained by mixing sorbitol, xylitol, dipropylene glycol and 1,4-butanediol in a weight ratio of 1: (1-1.1):(1-1.1):(1-1.1). According to the cement grinding aid disclosed by the invention, the polyether polyol suitable for the cement grinding aid is prepared, and the polyether polyol has a regulating effect in particle size of the cement particles, and can be used for strengthening the cement strength and making up the blank of the national polymer synthesis grinding aid.
