Efficient liquid grinding aid for cement

Abstract

The invention relates to an efficient liquid grinding aid for cement. The liquid grinding aid is prepared from the following components in percentage by weight: 48% of water, 5% of sodium sulfate, 2% of anhydrous sodium acetate, 10% of triethanolamine, 5% of ethylene glycol, 20% of sulfonated melamine resin and 10% of molasses. In the process of grinding the cement by using the liquid grinding aid, the liquid grinding aid accounting for 0.1-0.15wt% of the cement is added. The liquid grinding aid provided by the invention has the advantages that when the liquid grinding aid is added into the cement grinding process, the grinding efficiency is improved, the production energy consumption and the production cost are lowered, and meanwhile, the strength performance of cement is improved; under the condition of maintaining unchanged strength of cement, doping of mixed materials is improved while the use level of clinkers can be reduced, so that the production cost is further saved.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a high-efficiency cement liquid grinding aid. Background technique [0002] The existing cement liquid grinding aids have low grinding efficiency. When grinding cement, more liquid grinding aids need to be added, which increases the grinding cost and affects the quality of the produced cement. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency cement liquid grinding aid which can improve cement grinding efficiency, reduce grinding cost and improve cement performance. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: it is characterized in that: select tap water 48%, sodium sulfate 5%, anhydrous sodium acetate 2%, triethanolamine 10%, ethylene glycol 5%, 20% of sulfonated melamine resin and 10% of molasses are used as ingredients to manufacture liquid grinding ai...
