Description
Technical field
The invention belongs to cement grinding technical field, more particularly to a kind of high mill warm water cement grinding aids and preparation method thereof..
Background technology
What is added in cement grinding plays grind -aiding effect and does not damage the additional of health and cement concrete performance
Agent, referred to as grinding aid, it is divided into two kinds of powder and liquid.It is a kind of chemical addition agent for improving cement grinding effect and performance,
It is added in appropriate amount in the material by grinding, cement can be significantly improved by its physics chemical action to particle surface
Unit-hour output, each age strength of cement, improve its mobility.
Grinding aid is applied to manufacture of cement, can reduce clinker dosage, consumes industrial residue more, reduces cement grinding power consumption,
Significant effect in terms of energy-saving and emission-reduction；China is cement big country, if any 60% cement production enterprise application grinding aid, then can be economized on electricity
8100000000 more than Kwh, economize on coal more than 8,500,000 tons, reduce CO2、SO2 Discharge capacity of pernicious gas etc..
In the prior art, the alcamine compound in grinding machine in increased conventional cement grinding aid is volatile and rotten,
The performance of grinding aid is had a strong impact on, reduces the mill efficiency of grinding machine, declines the grindability of cement material, the grinding of grinding machine
Efficiency declines, and this is due to that common liq grinding aid mainly contains triethanolamine, polymerized polyalcohol, polyalcohol amine, three b propanols
Amine, ethylene glycol, propane diols, glycerine, sodium soap, calcium chloride, sodium chloride, sodium acetate, aluminum sulfate, calcium formate, calcium lignosulfonate, wooden sodium
Deng.Caused by the grindability of material declines with the rise of temperature, simultaneously as the rise of temperature, fine dust is easily because quiet
Electric attraction and assemble, cause slimeball phenomenon, also reduce the mill efficiency of grinding machine, cause cement mill unit-hour output decline.
The content of the invention
The present invention is directed to deficiency of the prior art, there is provided a kind of high mill warm water cement grinding aids and preparation method thereof.This is helped
Grinding agent can still improve cement mill unit-hour output in high grinding machine temperature, reduce cement grinding power consumption, improve cement early stage
And later strength.
