Embodiment 1
[0035] Embodiment 1: used cement liquid grinding aid is made up of triethanolamine, triisopropanolamine, ethylene glycol, adipate, polycarboxylic acid, molasses and water, and the weight percent of each component is as follows: triethanolamine 15%, triisopropanolamine 15%, ethylene glycol 10%, adipate 1%, polycarboxylic acid 20%, molasses 5%, and the rest is water. The water used therein is common tap water, and other components are all commercially available. The preparation steps are as follows: add ordinary tap water into the reaction kettle; add molasses, adipate, triethanolamine, triisopropanolamine, ethylene glycol and polycarboxylic acid to the reaction kettle sequentially while stirring; add all components After that, stir for 15 minutes; obtain cement liquid grinding aid.
Embodiment 2
[0036] Embodiment 2: used cement liquid grinding aid is made up of triethanolamine, triisopropanolamine, ethylene glycol, ethylene oxide propylene oxide copolymer, adipate, polycarboxylic acid, molasses and water, The weight percent of each component is as follows: triethanolamine 30%, triisopropanolamine 10%, ethylene glycol 5%, ethylene oxide propylene oxide copolymer 2%, adipate 1%, polycarboxylic acid 5% %, molasses 5%, and the rest is water. The water used therein is common tap water, and other components are all commercially available. The preparation steps are: add ordinary tap water into the reaction kettle; add molasses, adipate, triethanolamine, triisopropanolamine, ethylene glycol and polycarboxylic acid to the reaction kettle sequentially while stirring; add all the components Finally, stir for 15 minutes; the grinding aid liquid obtained after stirring and the ethylene oxide propylene oxide copolymer are emulsified and dispersed through an emulsifier; a highly un...
Embodiment 3
[0037] Embodiment 3: used cement liquid grinding aid is made up of triethanolamine, triisopropanolamine, ethylene glycol, ethylene oxide propylene oxide copolymer, adipate, polycarboxylic acid, molasses and water etc., The weight percentages of each component are as follows: 15% triethanolamine, 25% triisopropanolamine, 3% ethylene glycol, 3% ethylene oxide propylene oxide copolymer, 2% adipate, 5% polycarboxylic acid , molasses 5%, and the rest is water. The water used therein is common tap water, and other components are all commercially available. The preparation steps are the same as in Example 2.
