Embodiment 1

[0023] A liquid composite reinforced cement grinding aid, which is formulated by weight ratio from the following ingredients: 8 parts of sodium acetate, 15 parts of triethanolamine, 8 parts of ethylene glycol, 0.5 parts of block silicone oil, 30 parts of sulfamate, The rest is water. In the reaction kettle, the above-mentioned raw materials are mixed according to the weight ratio, and compounded according to the preparation process of the present invention to obtain the composite enhanced cement grinding aid. The dosage of the invention product in cement is 0.05% of the weight of cement (including mineral admixture). Weigh 5 kg of cement raw material and 2.5 g of grinding aid, and compare and analyze the physical and mechanical properties of the cement before and after the use of the grinding aid. After grinding in a ball mill for 25 minutes, the cement test results are shown in Table 1.

Embodiment 2

[0025] A liquid composite enhanced cement grinding aid, which is prepared by weight ratio from the following ingredients: 8 parts of sodium acetate, 5 parts of sodium thiosulfate, 10 parts of triethanolamine, 18 parts of diethanol isopropanolamine, block silicone oil 0.3 parts, 35 parts of sulfamate, and the rest is water. In the reaction kettle, the above-mentioned raw materials are mixed according to the weight ratio, and compounded according to the preparation process of the present invention to obtain the composite enhanced cement grinding aid. The dosage of the invention product in cement is 0.03% of the weight of cement (including mineral admixture). Weigh 5 kg of cement raw material and 1.5 g of grinding aid, and compare and analyze the physical and mechanical properties of the cement before and after the use of the grinding aid. After grinding in a ball mill for 25 minutes, the cement test results are shown in Table 1.

Embodiment 3

[0027] A liquid composite reinforced cement grinding aid, which is prepared by weight ratio from the following ingredients: 3 parts of sodium tripolyphosphate, 10 parts of sodium acetate, 15 parts of diethanolamine, 6 parts of tetrahydroxyethylhexamethylenediamine, block 0.2 parts of silicone oil, 10 parts of lignin iodate, 20 parts of sulfamate, and the rest is water. In the reaction kettle, the above-mentioned raw materials are mixed according to the weight ratio, and compounded according to the preparation process of the present invention to obtain the composite enhanced cement grinding aid. The dosage of the invention product in cement is 0.03% of the weight of cement (including mineral admixture). Weigh 5 kg of cement raw material and 2.5 g of grinding aid, and compare and analyze the physical and mechanical properties of the cement before and after the use of the grinding aid. After grinding in a ball mill for 25 minutes, the cement test results are shown in Table 1.

Abstract

The invention discloses a liquid compound reinforced type cement grinding aid. The liquid compound reinforced type cement grinding aid is prepared by the following ingredients in part by weight: 5 to 15 parts of reinforced compounds, 20 to 40 parts of grinding aiding compound, 0.1 to 1 part of silicon-contained compound, 10 to 50 parts of stable compounds, and the balance of water. The invention also discloses a preparation method of the liquid compound reinforced type cement grinding aid. The preparation method comprises the following steps: 1, adding water to a reacting kettle, and heating to reach 50 to 60 DEG C; 2, sequentially adding the reinforced component and the silicon-contained compound, and stirring for 30 minutes; 3, adding the stabile component and the grinding aiding component, and stirring for 10 minutes; and 4, adjusting the pH (Potential Of Hydrogen) of the solution to 8 to 9, and stirring for 10 minutes. The cement grinding aid disclosed by the invention can improve the physical and mechanical performances, and is low in dosage and free from harmful ingredients such as chlorine salt; and the preparation method of the cement grinding aid is simple in technological preparation and low in cost.

Description

technical field [0001] The invention relates to a liquid composite reinforced cement grinding aid and a preparation method thereof. Background technique [0002] According to statistics, in the cement industry, about 97% of the energy consumed in the grinding process is wasted as heat energy, and only a small part of the energy is used to increase the specific surface area of ​​the material. Therefore, saving energy and reducing consumption is an urgent task for cement production enterprises. Compared with other energy-saving and emission-reducing methods in the cement production process, using cement grinding aids to improve grinding efficiency is the most direct and effective method. Adding a small amount of cement grinding aid in the grinding process can increase the output under the same condition of cement fineness and mill power consumption, and can also increase the specific surface area of ​​cement under the same condition of cement output and mill power consumption....
