Problems solved by technology

[0004] In the prior art, the alcohol amine compound in the traditional cement grinding aid added in the mill is easy to volatilize and deteriorate, which seriously affects the performance of the grinding aid, reduces the grinding efficiency of the mill, and makes the cement material easy to grind. This is because the common liquid grinding aid mainly contains triethanolamine, polymer polyol, polymer alcohol amine, triethylene propanolamine, ethylene glycol, propylene glycol,

Abstract

The invention relates to the field of cement grinding aids and in particular relates to a high-mill-temperature cement grinding aid and a preparation method thereof. The high-mill-temperature cement grinding aid is characterized by being prepared from the following components in parts by mass: 30 to 60 parts of a mixed solution of aliphatic sodium sulfonate and aluminum sulfate, 1 to 10 parts of triethanolamine, 5 to 10 parts of alcamines, 1 to 10 parts of sodium tripolyphosphate, 1 to 10 parts of sodium gluconate, 0.1 to 5 parts of a dispersant and 10 to 30 parts of water. By adopting the high-mill-temperature cement grinding aid provided by the invention, the surface energy of a material can be reduced and an aggregation effect generated by molecular attraction is weakened; accelerated expansion of particle cracks are facilitated when an external force acts, so that the grinding efficiency is improved and the aims of high quality, energy saving and high yield of a ball mill are realized; the fineness of cement can be reduced and the output per machine hour of the ball mill can be improved.

Description

technical field [0001] The invention belongs to the technical field of cement grinding, and in particular relates to a high grinding temperature cement grinding aid and a preparation method thereof. . Background technique [0002] The admixture added during cement grinding to aid in grinding without harming human health and the performance of cement concrete is called grinding aid, which is divided into two types: powder and liquid. It is a chemical additive to improve the grinding effect and performance of cement. It can be added to the material to be ground in an appropriate amount. Through its physical and chemical effects on the surface of the particles, it can significantly increase the output of the cement table and the strength of cement at all ages. , to improve its fluidity. [0003] The application of grinding aids in cement production can reduce the amount of clinker, consume more industrial waste residues, reduce the power consumption of cement grinding, and ha...
