Embodiment 1

[0020] To prepare 100 kg of high-efficiency activated cement grinding aid, weigh 18 kg of triethanolamine, 10 kg of triisopropanolamine, 7 kg of sodium carbonate, 5 kg of ethylene glycol, 30 kg of water, 5 kg of toluene, 2 kg of silica fume, and 15 kg of black liquor and 8 kg of waste liquor from sugar factories.

[0021] Its preparation method comprises the following steps:

[0022] (1) First add silica fume to toluene, stir to dissolve it and set aside;

[0023] (2) Add triisopropanolamine to water and heat to 50°C to dissolve it quickly;

[0024] (3) Add sodium carbonate, toluene dissolved in silica fume, papermaking black liquor, sugar factory waste liquor, ethylene glycol, and triethanolamine in sequence while stirring in step (2), and finally stir evenly to obtain the finished product.

[0025] The dosage of grinding aid in this embodiment is 0.1% / ton of cement. Two samples of 5kg of cement raw material and 5g of grinding aid were weighed respectively, and tested. The...

Embodiment 2

[0033] To prepare 100 kg of high-efficiency activated cement grinding aid, weigh 20 kg of triethanolamine, 8 kg of triisopropanolamine, 10 kg of sodium carbonate, 3 kg of ethylene glycol, 30 kg of water, 8 kg of toluene, 3 kg of silica fume, and 13 kg of black liquor and 5 kg of waste liquor from sugar factories. The preparation method is the same as in Example 1.

Embodiment 3

[0035] To prepare 100 kg of high-efficiency activated cement grinding aid, weigh 15 kg of triethanolamine, 5 kg of triisopropanolamine, 10 kg of sodium carbonate, 5 kg of propylene glycol, 25 kg of water, 7 kg of toluene, 3 kg of silica fume, papermaking black liquor 20 kg, 10 kg of sugar factory waste liquid.

Abstract

The invention discloses an efficient activating cement grinding aid, which comprises triethanolamine, triisopropanolamine, ethylene glycol or propylene glycol, sodium carbonate and water. The efficient activating cement grinding aid is characterized in that the efficient activating cement grinding aid further comprises toluene, silica fume, paper-making black liquor and waste liquor from a sugar plant, wherein the weight percentages of the components are as follows: 15 percent to 20 percent of triethanolamine, 5 percent to 10 percent of triisopropanolamine, 3 percent to 8 percent of ethylene glycol or propylene glycol, 5 percent to 10 percent of sodium carbonate, 25 percent to 40 percent of water, 3 percent to 8 percent of toluene, 1 percent to 3 percent of silica fume, 10 percent to 20 percent of paper-making black liquor and 5 percent to 10 percent of waste liquor from the sugar plant. The grinding aid has the advantages that raw materials are easy to obtain, the cost is low, the adding content is small, and the compressive strength of cement can be increased while the yield of a grinding mill can be increased.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a high-efficiency activated cement grinding aid and a preparation method thereof. Background technique [0002] Grinding is a necessary process and key link in cement production. Its energy consumption and electricity consumption account for 30% of the total energy consumption and more than 70% of the total electricity consumption of cement production. At present, the country's low-carbon environmental protection requirements are getting higher and higher, the price of cement is sluggish, the price of raw materials and energy is rising, and the industry competition is fierce, which makes the benefits of cement enterprises stretched. In order to survive, cement enterprises must carry out technological updates, continuously reduce cement production costs, and save energy to create benefits. Adding cement grinding aids can solve the problems of high grinding power consump...
