Polybasic and multifunctional liquid cement grinding aid and production technology thereof

Abstract

The invention discloses a polybasic and multifunctional liquid cement grinding aid and production technology of the polybasic and multifunctional liquid cement grinding aid. The polybasic and multifunctional liquid cement grinding aid and the production technology of the polybasic and multifunctional liquid cement grinding aid are characterized by comprising the following raw materials of tri ethanol amine, polymerization polybasic alcohol and water. The raw materials comprise, by weight percentage, 60 percent of the tri ethanol amine, 20 percent of the polymerization polybasic alcohol and 20 percent of the water. The production technology comprises the following steps. Firstly, weighing is performed based on proportion, and the raw materials are prepared. Secondly, the water is heated to 80 DEG C by a boiler and put in a reaction kettle, the polymerization polybasic alcohol is added, and meanwhile, the reaction kettle is started for stirring for 20 minutes. The tri ethanol amine is then added and stirred for 3 hours and cooling is performed. Thirdly, after the solution is cooled, the solution is transferred into an end product jar, and production is finished. The liquid cement grinding aid is high in comprehensive use performance, plasticity protection performance of cement mixed plastic soil is improved, and the liquid cement grinding aid has good compatibility with a concrete high-efficiency slushing agent. Comprehensive performance of cement is improved, in addition, the production technology is simple, short in production time, and high in production yield.

Description

technical field [0001] The invention relates to a cement grinding aid and a production process thereof, in particular to a multi-component multifunctional liquid cement grinding aid and a production process thereof. Background technique [0002] With the in-depth development of the "Western Development" and the improvement of the level of urbanization, there are more and more basic projects such as urban construction, roads, and bridges. Therefore, the demand for cement continues to grow rapidly. [0003] In cement production, cement grinding aid is an essential raw material to improve cement quality and output. Cement grinding aid is a chemical additive to improve the grinding effect and performance of cement. It can significantly increase the output of cement, the strength of cement of all ages, and improve its fluidity. Specifically, cement grinding aid has the following functions: 1. It can greatly reduce the phenomenon of electrostatic adsorption and encapsulation form...

AI Technical Summary

Problems solved by technology

[0006] Due to the unscientific formula and rough production process of the existing liquid cement grinding aids, the cement mortar prepared by using the liquid cement grinding aids has poor plasticity and poor workability, and is not compatible with the high-efficiency of preparing high-performance concrete. Poor compatibility of water reducing agent, etc., the loss of sag over time increases the cost of materials for high-performance concrete to meet the main functions
