Problems solved by technology

[0004] All there are some defects in the formula composition of these liquid grinding aids: due to the increasing shortage of world oil resources, the prices of the main raw material triethanolamine and organosilicon polymer (certain siloxane) of grinding aids are also constantly rising, seeking A relatively low-cost and effective slag grinding aid product is an urgent problem to be solved in the domestic grinding aid industry, and slag micropowder production enterprises require that the output of the mill be increased by more than 14% in order to further reduce electricity consumption. consumption, save energy

Abstract

The invention discloses a blast furnace slag liquid grinding aid, which comprises the following components by mass percentage: 10%-20% of diglycol, 10%-15% of cane sugar slag waste liquid, 10%-20% of sorbitol, 10%-20% of glycerin, 1-5% of sodium tripolyphosophate, 1-10% of sodium carbonate, and the remainder being water. The grinding aid prepared by the invention has the advantages of remarkably improving slag grinding output, enhancing slag micro powder strength, easily purchasing raw materials with low cost and the like. The further optimized scheme for the invention is as follows: 1-5% of glycol and 1-5% of sodium dodecyl benzene sulfonate by mass percentage are added into the grinding aid, which can further enhance the effect of slag grinding efficiency. At the same time, the invention also discloses a preparation method of the liquid cement grinding aid.

Description

technical field [0001] The invention relates to a slag grinding aid in the field of blast furnace slag fine powder manufacturing, in particular to a blast furnace slag liquid grinding aid and a preparation method thereof. Background technique [0002] Slag micropowder is a new type of green environmental protection product. It can not only effectively utilize blast furnace metallurgical slag, turn waste into treasure, but also play a role in reducing the land occupation of slag and reducing environmental pollution. Slag micropowder has become one of the preferred materials for producing high-quality cement, high-performance, large-volume, and long-life concrete. Concrete mixed with slag micropowder has the characteristics of low heat of hydration, corrosion resistance, good fluidity, high late strength, anti-shrinkage, and can improve the bonding performance of the concrete interface. It has been identified as one of the ten new technologies in the construction industry by t...
