Views:24     Author:Sam     Publish Time: 2018-06-27      Origin:Site Inquire

The use of maleic anhydride (MA) and triethanolamine (TEA) polymerization to obtain intermediate M, and then with isoprenol polyoxyethylene ether (TPEG), acrylic acid (AA) polymerized under aqueous conditions to obtain polycarboxylic acid - Alkanolamine cement grinding aids, and explored the effects of alcohol amine molecular species, grafting density and content on cement grinding and reinforcement. The results showed that when n(M):n(AA):n(TPEG =) 1:1:0.3. When the grinding aid additive content is 0.05%, the grinding aid and the cement reinforcement effect are the best.
