Embodiment 1

[0024] First, add 5 kg of sodium hexametaphosphate to 90 kg of water, heat and stir slightly, the temperature is 20 ° C, after it is completely dissolved, add 5 kg of sodium lauryl sulfate into the solution, continue heating, the temperature does not exceed 38°C, stirring and dissolving. Finally, 18 kg of trimixed alcohol, 7 kg of ethyl acetate and 8 kg of molasses were added to the solution, stirred evenly, and then cooled and filtered. The mixed alcohol is a mixture of two or three of industrial grade ethylene glycol, diethylene glycol and triethylene glycol.

Embodiment 2

[0026] First, add 2 kg of sodium hexametaphosphate to 95 kg of water, heat and stir slightly, the temperature is 20 ° C, after it is completely dissolved, add 2 kg of sodium lauryl sulfate into the solution, continue heating, the temperature does not exceed 38°C, stirring and dissolving. Finally, 17 kg of trimixed alcohol, 8 kg of ethyl acetate and 8 kg of molasses were added to the solution, stirred evenly, and then cooled and filtered. The mixed alcohol is a mixture of two or three of industrial grade ethylene glycol, diethylene glycol and triethylene glycol.

Embodiment 3

[0028] First, add 1 kg of sodium hexametaphosphate to 85 kg of water, heat and stir slightly, the temperature is 20°C, after it is completely dissolved, add 1 kg of sodium lauryl sulfate into the solution, continue heating, the temperature does not exceed 38°C, stirring and dissolving. Finally, 16 kilograms of trimixed alcohol, 6 kilograms of ethyl acetate and 6 kilograms of molasses were added into the solution and stirred evenly, and the mixture was cooled and filtered. The mixed alcohol is a mixture of two or three of industrial grade ethylene glycol, diethylene glycol and triethylene glycol.

Abstract

The invention relates to a mineral waste residue liquid composite grinding aid and a preparation method thereof. The mineral waste residue liquid composite grinding aid is prepared from the following raw materials: 15-20 parts by weight of mixed alcohol, 5-10 parts by weight of ethyl acetate, 5-10 parts by weight of molasses, 1-10 parts by weight of lauryl sodium sulfate, 1-10 parts by weight of sodium hexametaphosphate and 800-100 parts by weight of water. The mineral waste residue liquid composite grinding aid has low toxicity, does not volatile and is stable in sources, sufficient in supplies, simple to process and prepare and low in cost; after granulated blast-furnace slag is doped in the mineral waste residue liquid composite grinding aid, the distribution and the morphology of separate particles can be improved, and the quality of mineral waste residue micro powder is not affected; the mineral waste residue liquid composite grinding aid has the advantages of increasing the yield and improving the quality of the mineral waste residue micro powder and meanwhile greatly reduces the energy consumption. The mineral waste residue liquid composite grinding aid has stable property, high cost performance and wide adaptability, is low in cost and mixing amount and can be used for improving the grinding effect and increasing the yield of a grinder by above 15%, the specific surface area of the mineral waste residue micro powder by 4.7%-6.2% under the condition of the same grinding time and the activity index of the mineral waste residue micro powder.

Description

technical field [0001] The invention relates to an additive in the field of slag fine powder production. Specifically, the present invention relates to a slag liquid composite grinding aid, and in addition, the present invention also relates to a preparation method of the slag liquid composite grinding aid. Background technique [0002] Granulated blast furnace slag is the main waste slag produced when smelting pig iron. According to the calculation of about 0.5 tons of slag produced in the production of 1 ton of pig iron, the granulated blast furnace slag produced nationwide in 2012 alone was about 360 million tons. How to utilize slag solid waste is a subject that Chinese metallurgists have been studying for many years, and it is also a practical problem that should be solved emphatically in developing circular economy and building a conservation-minded and environment-friendly society. Because granulated blast furnace slag is used as cement active admixture in cement...
