Cement grinding aid with high agglomeration performance and preparation method thereof

Abstract

The invention discloses a cement grinding aid with high agglomeration performance, and belongs to the technical field of building materials. The cement grinding aid is prepared from the following rawmaterials in percentage by weight: 5-10% of diesel oil, 1-3% of methyl alcohol, 1-3% of nekal, 3-5% of polymeric alkylol amine, 3-8% of glycol, 5-12% of triethanolamine, 3-5% of molasses, 1-6% of sodium phosphate, 1-3% of sodium lignin sulfonate, 5-20% of sorbitol, 5-20% of sodium thiocyanate, and the balance of water. Through stirring, dissolving and still standing, the cement grinding aid is obtained. The preparation principle is clear, a method is scientific, compared with the prior art, the production cost is lower, a production process is simple, the admixture amount is low, the enhancement effect is good, the agglomeration performance of cement can be improved, the output of the cement can be increased, and the cement grinding aid is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a cement grinding aid and a preparation method thereof, in particular to a cement grinding aid with high agglomeration performance and a preparation method thereof. Background technique [0002] In the grinding process of cement clinker, adding a small amount of additional substances (liquid or solid substances) can significantly improve the grinding efficiency or reduce energy consumption without damaging the performance of cement. The chemical additives are commonly referred to as: Cement grinding aid. Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. It can significantly increase the output of cement table, the strength of cement of all ages, and improve its fluidity. Cement grinding aids can greatly reduce the phenomenon of electrostatic adsorption and ball formation during the grinding process, and can reduce th...
