Problems solved by technology

At present, although some cement grinding aids produced on the market can increase the amount of admixtures, they affect the growth of cement strength in the later stage; there are still some cement grinding aids that can meet the requirements of both admixtures and cement strength. Requirements, but production costs are too high

Embodiment 1

[0016] Example 1 An energy-saving enhanced cement liquid grinding aid is composed of the following raw materials in mass percentage: 5% triethanolamine, 2% sodium tripolyphosphate, 6% aluminum sulfate solution, 3% sodium dodecylbenzenesulfonate %, diethylene glycol 7%, sodium acetate 10%, and the balance is water.

[0017] The preparation method of the grinding aid: After weighing each raw material according to the proportion, first pour water into the reaction kettle, and heat it to 70-80°C; then add sodium tripolyphosphate and aluminum sulfate solution, and stir for 20 minutes Add sodium dodecylbenzenesulfonate and sodium acetate, and stir for another 10 minutes; then add diethylene glycol and stir for 10 minutes, then add triethanolamine, and finally stir for another 20 minutes.

Embodiment 2

[0018] Example 2 An energy-saving enhanced cement liquid grinding aid, consisting of the following raw materials in mass percentage: 10% triethanolamine, 5% sodium tripolyphosphate, 8% aluminum sulfate solution, 9% sodium dodecylbenzenesulfonate %, diethylene glycol 10%, sodium acetate 7%, and the balance is water.

[0019] The preparation method of this grinding aid is with embodiment 1.

Abstract

The invention relates to an energy-saving reinforced type liquid grinding aid for cement, which comprises the following raw materials in percentage by weight: 5-15% of triethanol amine, 1-10% of sodium tripolyphosphate, 5-10% of aluminum sulfate solution, 3-10% of sodium dodecyl benzene sulfonate, 5-10% of diethylene glycol, 5-10% of sodium acetate and the balance of water. The liquid grinding aid is favorable for not only improving cement production efficiency and cement specific surface area, but also improving cement compression strength and increasing the addition of admixtures. Meanwhile, the invention further discloses a preparation method of the grinding aid.

Description

technical field [0001] The invention relates to the field of cement production, in particular to an energy-saving enhanced cement liquid grinding aid and a preparation method thereof. Background technique [0002] Energy saving and consumption reduction is an urgent task for cement production enterprises. Compared with other energy saving and emission reduction methods in the cement production process, the use of cement grinding aids hardly requires any investment in fixed assets, and can also improve the grinding efficiency of the mill. , Reduce cement power consumption, increase the amount of mixed materials, save cement costs, and enhance the market competitiveness of cement manufacturers. At present, although some cement grinding aids produced on the market can increase the amount of admixtures, they affect the growth of cement strength in the later stage; there are still some cement grinding aids that can meet the requirements of both admixtures and cement strength. re...
