Embodiment 1

[0022] A kind of slag, steel slag grinding aid activator, its manufacture method is: firstly add 38kg tap water (temperature 20-35 ℃) in reaction kettle, then add 12kg yuanming powder and 8kg caustic soda into water, stir 15-20 minutes, Until the sodium sulfate and caustic soda are completely dissolved in water, then add 10kg of lactose, 8kg of propylene glycol, 10kg of ethylene glycol, 6kg of polyamide, 5kg of oleic acid, and 3kg of compound additives, and stir for 20-30 minutes to obtain slag and steel slag grinding aids. Activator products.

[0023] The preparation method of the composite auxiliary agent is as follows: a. Take attapulgite, pyrophyllite and illite in a mass ratio of 5:3:2, mix them uniformly and put them into a hydrochloric acid solution with a concentration of 20%, and heat them in a water bath to 80 ℃, keep warm for 0.5h, take it out and wash it with distilled water until neutral, wet ball mill for 24h, dry it, and after calcination at 840℃ for 2h, heat up...

Embodiment 2

[0025] A kind of slag, steel slag grinding aid activator, its manufacture method is: firstly add 41kg tap water (temperature 20-35 ℃) in reaction kettle, then add 10kg yuanming powder and 6kg caustic soda into water, stir 15-20 minutes, until Yuanming powder and caustic soda are completely dissolved in water, then, add 14kg of lactose, 9kg of propylene glycol, 7kg of ethylene glycol, 7kg of polyamide, 4kg of oleic acid, and 2kg of compound additives, and stir for 20-30 minutes to obtain slag and steel slag grinding aids.

Abstract

The invention discloses a slag and steel slag grinding-assisted activating agent. The slag and steel slag grinding-assisted activating agent is prepared from the following raw materials in percentage by mass: 7 to 15 percent of lactose, 6 to 14 percent of propylene glycol, 5 to 15 percent of glycol, 4 to 10 percent of polyamide, 3 to 7 percent of oleic acid, 6 to 13 percent of anhydrous sodium sulfate, 5 to 12 percent of caustic soda, 2 to 4 percent of composite aid and the balance of water. The slag and steel slag grinding-assisted activating agent is used for grinding slag and steel slag, can increase the hourly output of a grinding machine by 10 to 16 percent and reduce the grinding power consumption by 7 to 13 percent, and also can increase the activity index of the slag and the steel slag by above 8 percent.

Description

Technical field: [0001] The invention mainly relates to the production field of slag and steel slag micropowder, in particular to a grinding aid activator for slag and steel slag. Background technique: [0002] Slag is the waste residue produced by blast furnace ironmaking. Because of its good potential hydration activity, it is widely used as an admixture in cement and concrete. It can not only save cement clinker, but also improve the durability and fluidity of concrete. , heat of hydration and a series of properties. Now slag has become an important building material raw material. [0003] Steel slag is the waste slag produced by blast furnace steelmaking. Its physical and chemical properties are similar to slag, but its activity is lower than that of slag. Due to the shortage of slag resources and the high price, steel slag powder is now more and more used as an admixture in cement and concrete. [0004] Slag and steel slag must be ground to a specific surface area of...
