Abstract

The invention relates to multifunctional polymer slurry powder and a preparation method thereof. The multifunctional polymer slurry powder is mainly prepared from 30 to 80 parts of slurry making agents, 1 to 20 parts of wall protection stabilizing agents, 1 to 20 parts of slag settling agents, 1 to 15 parts of dissolution promotion agents and 1 to 15 parts of regulating agents in parts by weight through compounding preparation. The multifunctional polymer slurry powder has the main characteristics that the technical flow process is reasonable and simple; the production efficiency is high; thepackaging and the transportation are convenient and fast; no contaminants are discharged; the cost is low. Compared with the prior art, the multifunctional polymer slurry powder produced by using themethod has the advantages of small specific weight, little addition, fast dissolution, high viscosity, low filter loss, little settled slag quantity, few circulation times, no pollution and the like,and has good application prospects in pile foundation construction.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a multifunctional polymer mud powder and a preparation method thereof. Background technique [0002] Mud is a vital and necessary material in drilling construction. Poor drilling mud will have the following effects: (1) The mud film cannot be formed or the mud skin adhesion is not good, which is easy to cause shedding and stabilize the hole wall Not enough, which is prone to shrinkage and hole collapse. (2) The mud with large specific gravity, low consistency and high sand content will form a thick mud skin, which will increase the side friction resistance of the pile. (3) Thick slurry deposits and adheres to the reinforcement cage, which reduces the gripping force between reinforcement and concrete. (4) The mud with too large specific gravity increases the resistance of concrete pouring underwater, reduces the flow radius of concrete, and accumulates most of the concrete ...
