Preparation method of cement water reducer

Abstract

The invention relates to the technical field of preparation of cement additives, in particular to a preparation method of a cement water reducing agent, the preparation method of the cement water reducing agent is completed through cooperation of water reducing agent stirring equipment, the water reducing agent stirring equipment comprises a stirring kettle, and a stirring part is arranged at the central axis position in the stirring kettle; the upper end of the stirring part penetrates through the stirring kettle and is connected to the upper side face of the stirring kettle, a stacking plate is arranged in the lower end of the stirring kettle, the lower end of the stirring part penetrates through the stacking plate and is in sealing fit with the stacking plate, and bottom stirring rods are symmetrically installed on the outer side face of the lower end of the stirring part and located above the stacking plate. An additive solution in the stirring kettle is stirred in a manner of angle adjustment and up-and-down movement of the stirring rod, so that the additive solution cannot be layered, and the problems that the layering phenomenon cannot be generated when the solution is stirred only through modeling arrangement of stirring blades, and burden is caused to a motor due to the fact that the stirring blades are too large are solved.

Description

technical field [0001] The invention relates to the technical field of preparation of cement additives, in particular to a preparation method of a cement water reducer. Background technique [0002] Cement water reducer plays a dispersing role on cement particles, which can improve the workability of cement and reduce unit water consumption, thereby improving the fluidity of concrete mixtures. The appearance of cement water reducing agent is divided into water agent and powder; according to the water reducing and enhancing ability of water reducing agent, it is divided into ordinary water reducing agent, high-efficiency water reducing agent and high-performance water reducing agent. [0003] In the preparation process of the cement water reducing agent, the additives need to be stirred and prepared first, and then the raw materials are subjected to sulfonation, condensation and other operation steps and additives are added in the steps, and then the water reducing agent can ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the following problems in the existing mixing of cement superplasticizer additives, the mixing blade can not be able to solve the stratification phenomenon caused by solution stirring only through the setting of the shape, and the stirring blade is too large to cause a burden on the motor. During the mixing process of the water reducing agent Particles will be generated, and a large number of impurities will affect the subsequent stirring of the solution. Now the common practice is to remove the impurities after the solution is allowed to stand. This method will reduce the preparation efficiency of the water reducer.
