Problems solved by technology

[0002] In cement production, when clinker, gypsum and other mixed materials are in the grinding process, static electricity will be generated between the materials and the mill and the materials due to the impact of each other, resulting in serious balling phenomenon in the cement mill, affecting Production efficiency and quality assurance of cement
At present, although the cement grinding aids produced at home and abroad can eliminate this problem, the cost is relatively high

Embodiment 1

[0015] Embodiment 1 A high-efficiency cement grinding aid, which is composed of the following raw materials in mass percentage: 5% triethanolamine, 5% sodium tripolyphosphate, 2% lignosulfonate, dodecylbenzenesulfonate sodium thiosulfate 2%, sodium thiosulfate 5%, sodium benzoate 1%, alkyl polyglycoside 5%, and the balance is water.

[0016] The preparation method of the grinding aid: After weighing each raw material according to the proportion, first add triethanolamine into water at room temperature, then add sodium tripolyphosphate and lignosulfonate and stir for 20 minutes, then add lauryl Sodium benzenesulfonate and sodium thiosulfate were stirred for 20 minutes, then sodium benzoate was added and stirred for 10 minutes, and finally alkylpolyglycoside was added and stirred for 10 minutes.

Embodiment 2

[0017] Embodiment 2 A high-efficiency cement grinding aid, which is composed of the following raw materials in mass percentage: 7% triethanolamine, 5% sodium tripolyphosphate, 5% lignosulfonate, dodecylbenzenesulfonate sodium thiosulfate 4%, sodium thiosulfate 7%, sodium benzoate 2%, alkyl polyglycoside 6%, and the balance is water.

[0018] The preparation method of this grinding aid is with embodiment 1.

Abstract

The invention relates to an efficient cement grinding aid which comprises the following raw materials in percent by mass: 5-15 percent of triethanolamine, 5-10 percent of sodium tripolyphosphate, 2-10 percent of lignosulfonate, 2-5 percent of sodium dodecyl benzene sulfonate, 5-10 percent of sodium thiosulfate, 1-5 percent of trisodium benzoyl, 5-10 percent of alkyl polyglycosides and the balanceof water. After the efficient cement grinding aid is adopted, during the production of each ton of cement and under the condition of smaller doping ratio, the production efficiency of the cement and the specific area of the cement can be improved, the compression strength of the cement can be increased, and the addition quantity of mixture materials is increased; while the addition quantity of the grinding aid is reduced, and the requirements for saving energy and improving the yield of the cement are ensured. Meanwhile, the invention also discloses a preparation method of the grinding aid.

Description

technical field [0001] The invention relates to the field of cement production, in particular to a high-efficiency cement grinding aid and a preparation method thereof. Background technique [0002] In cement production, when clinker, gypsum and other mixed materials are in the grinding process, static electricity will be generated between the materials and the mill and the materials due to the impact of each other, resulting in serious balling phenomenon in the cement mill, affecting Cement production efficiency and quality assurance. At present, although the cement grinding aids produced at home and abroad can eliminate this problem, the cost is relatively high. [0003] At the same time, energy saving and consumption reduction is an urgent task for cement production enterprises. Compared with other energy saving and emission reduction methods in the cement production process, a cement grinding aid with excellent performance can improve the grinding efficiency of the mill...
