Problems solved by technology

[0003] At present, in cement production, when using liquid cement grinding aids to manufacture cement, the grinding efficiency of the mill is low, and the strength of the cement is low. Most of the existing grinding aids contain chloride ions, sulfate ions, and ammonium ions. And phosphate ions, due to the existence of these ions, affect the characteristics of cement, will cause corrosion to the metal in the building, affect the durability of the building, and the cost and cost of some grinding aids on the market are high, the production process Also relatively complex and not suitable for a wide range of industrial applications

Abstract

The invention discloses a liquid cement grinding aid enhancer and a preparation method thereof and belongs to the technical field of cement manufacturing; the liquid cement grinding aid enhancer is made from, by weight, 20-32 parts of triethanolamine, 8-14 parts of ethylene glycol, 4-10 parts of potassium fulvate, 6-10 parts of sodium citrate, 2-6 parts of Alpha-terpilenol, 10-20 parts of acetophenone, 3-7 parts of polydimethylsiloxane, 4-8 parts of polytetrahydrofuran glycol, 1-5 parts of isofucosterol, 2-6 parts of sulfobetaine, and 24-36 parts of water; the cement grinding aid enhancer provided herein can provide increased cement mark level and improved cement strength at the premise of equal cement material ratio; usage of cement clinker can be reduced, cement output per machine can also be increased, energy consumption is reduced, comprehensive cost of cement is reduced, and the enhancer is safe and nontoxic and is widely applicable.

Description

technical field [0001] The invention belongs to the technical field of cement manufacture, and in particular relates to a liquid cement grinding aid enhancer and a preparation method thereof. Background technique [0002] In the grinding process of cement clinker, adding a small amount of additional substances can significantly improve the grinding efficiency or reduce energy consumption without damaging the performance of cement. The chemical additives are collectively referred to as: cement grinding aids; cement Grinding aid enhancer is a chemical additive to improve 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. The cement grinding aid can greatly reduce the grinding process. The formed electrostatic adsorption encapsulation phenomenon can reduce the re-agglomeration tendency of ultrafine particles formed during the grinding process; the cement grinding ...
