Abstract

The invention discloses a high grinding temperature compound liquid grinding aid consisting of the following components by mass percent: 30-50% of 12% polyvinyl alcohol aqueous solution, 1-5% of sodium tripolyphosphate, 0.01-5% of sodium gluconate, 5-15% of ethylene glycol, 0.01-0.05%, 40% of sodium dodecyl benzene sulfonate, 10%-15% of 40% cane sugar residue fluid and the balance of water. The high grinding temperature compound liquid grinding aid solves the problem that normal liquid grinding aids lose original utility of the grinding aid in a cement mill with the temperature higher than 120 degrees centigrade so as to significantly improve the liquidity of cements, increase the grinding efficiency of the mill, significantly increase the machine-hour yield of the mill, improve the adaptability of cement grinding aid and concrete water reducer and significantly improve the early strength of the cements and suitably increase the long-term strength of the cements.

Description

technical field

[0001] The invention relates to a high grinding temperature composite liquid grinding aid 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 and reduce energy consumption without affecting the original performance of cement. For: 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 electrostatic adsorption formed during the grinding process, greatly reduce the phenomenon of ball encapsulation, and can reduce the re-agglomeration tendency of ultrafine particles formed during the grinding process. Cement grinding aids can also significantly improve ...
