Example Embodiment

[0013] Example 1: The component weight percentages of the cement composite grinding aid are modified triethanolamine 15%, triethanolamine 10%, triisopropanolamine 22%, glycerol 15%, sodium humate 10%, and low molecular weight Fatty salt 1% and clean water 27%.

[0014] The cement composite grinding aid made based on this composition ratio is added to the material, the cement strength is obviously enhanced, the energy consumption is reduced, and the grinding output of the ball mill is increased by more than 15%.

Abstract

The invention provides a cement compound type grinding aid which is high-efficient cement grinding aid integrating grinding and enhancement. The cement compound type grinding aid comprises the following compositions in percentage by weight: 10-20% of modified triethanolamine, 10-15% of triethanolamine, 20-30% of triisopropanolamine, 10-15% of glycerinum, 10-15% of sodium humate, 1% of low-molecular-weight fatty salt and 20-30% of clean water. According to the cement compound type grinding aid, the grinding efficiency of a cement grinding technology and the purification of the working environment in a manufacturing shop can be effectively improved, and the cement compound type grinding aid has the characteristics of lowering the production cost and effectively optimizing the properties of cement.

Description

technical field [0001] The invention relates to building material chemical products, in particular to a cement composite grinding aid, in particular to a high-efficiency cement grinding aid integrating grinding aid and reinforcement. Background technique [0002] Cement is one of the most commonly used building materials and is widely used in civil engineering, hydraulic, national defense and other projects. During the processing of cement, it needs to be ground into powder with a mill. According to the existing cement grinding process, the mill Over-grinding often occurs in the warehouse, resulting in electrostatic adsorption, and the temperature of the clinker entering the mill is extremely high, even reaching 190 degrees. The solution to this situation is usually to add cement grinding aids. Most of the commercially available liquid grinding aids are composed of pure chemical substances such as triethanolamine and industrial waste. The cost of grinding aids is very high a...
