Embodiment 1

[0011] First, add 0.5 kg of polyacrylamide to 50 kg of water, heat and stir slightly (the temperature does not exceed 60 ° C), and after it is completely dissolved, add 10 kg of calcium chloride into it, stir and dissolve, and then add 3 kg of calcium chloride Calcium formate was added therein and stirred to dissolve. Then add 6.5 kg of sodium gluconate to fully dissolve it, and finally add 10 kg of ethylene glycol and 20 kg of triethanolamine and stir evenly. The added weight percentage of the grinding aid in the cement is 0.04%. Weigh 5 kg of cement raw materials and 2 grams of grinding aid, respectively adopt natural gypsum and desulfurized gypsum as blank samples, grind for 31 minutes through a test ball mill, and then take samples according to GB / T17671-1999 "Cement mortar strength test method (ISO) method "Tested, the results of the cement test are shown in Table 1 and Table 2.

[0012] Table 1 adopts natural gypsum as the cement test effect data of blank sample

Embodiment 2

[0020] First, add 0.5 kg of polyacrylamide to 50 kg of water, heat and stir slightly (the temperature does not exceed 60°C), and after it is completely dissolved, add 6.5 kg of sodium carbonate into it, stir and dissolve, and then add 3 kg of formic acid Calcium was added therein and stirred to dissolve. Then add 8 kilograms of sodium gluconate to make it fully dissolved. Finally, 12 kg of propylene glycol and 20 kg of triethanolamine are added and stirred evenly.

Embodiment 3

[0022] First, add 0.5 kg of polyacrylamide to 45 kg of water, heat and stir slightly (the temperature does not exceed 60°C), and after it is completely dissolved, add 9.5 kg of calcium chloride into it, stir and dissolve, and then add 3 kg of calcium chloride Calcium formate was added therein and stirred to dissolve. Then add 7 kg of sodium gluconate to fully dissolve it. Finally, 15 kg of ethylene glycol and 20 kg of triethanolamine are added and stirred evenly.

Abstract

The invention discloses a high-efficiency energy-saving cement grinding aid and a preparation method thereof. The high-efficiency energy-saving cement grinding aid comprises the following components in parts by weight: 10 to 25 parts of triethanolamine, 0.5 to 1 part of polyacrylamide, 3 to 5 parts of calcium formate, 5 to 8 parts of sodium gluconate, 5 to 10 parts of basic salt, 10 to 15 parts of stabilizing agent, and 25 to 50 parts of water. When the general content of added cement grinding aids is 0.04 percent, the output of a grinding mill can be increased by over 10 percent, and the three-day and twenty-eight-day compressive strengths of the cement can be increased by about 15 percent.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving cement grinding aid and a preparation method thereof, belonging to the technical field of cement. Background technique [0002] In recent years, the scale of my country's industrialization has increased rapidly, and it has gradually changed from a large energy country with abundant resources to a large energy import country. Energy has become a bottleneck restricting my country's economic development, especially the cement plant, which is a large energy consumer, is even more difficult to get the support of national policies. If cement enterprises want to survive, they must rely on technological innovation to continuously reduce costs and save energy consumption. [0003] In order to solve the problems of high grinding power consumption, low grinding efficiency, improve cement strength and other properties, increase the amount of mixed materials, and reduce costs in the process of cement pro...
