Lubricant for pipeline earth moving machine and preparation method thereof

Abstract

The invention discloses a lubricating agent for a pipelineearth moving machine and a preparation method thereof, which relate to the technical field of lubricating agents. The lubricating agent is prepared from the following components: carboxymethylcellulose, pottery clay powder, metallic soap, stearic acid, polyethylene wax, glyceryl monostearate, octadecanamide, an emulgator, ethylalcohol, an adhesive and water. The preparation method of the lubricating agent comprises the following steps: S1, adding the carboxymethylcellulose, the pottery clay powder, the glyceryl monostearate, the polyethylene wax and the metallic soap into the water, heating and stirring to obtaining mixed liquid I; S2, adding the octadecanamide, the stearic acid and the ethyl alcohol into the mixed liquid I, rising temperature, stirring, and mixing to obtain mixed liquid II; S3, adding the emulgator and the adhesive into the mixed liquid II, and stirring uniformly to obtain the lubricating agent. According to the lubricating agent provided by the invention, an inner wall of a pipeline can be effectively lubricated, the friction between a soil body and the inner wall of the pipeline is reduced, and the conveying length of the soil body is increased, so that a pipeline earth moving technology can be quickly applied in imperative urban construction.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a lubricant for pipeline soil moving machines and a preparation method thereof. Background technique [0002] In the construction process of existing underground projects, the method of pumping soil moving equipment through pipelines is mainly used to transport and transfer a large amount of excavated soil in the space of the construction site, for example, horizontal transportation, inclined transportation, first horizontal and then inclined transportation , first horizontally and then vertically upward conveying and other conveying ways. During the transportation of soil, there is often a large friction between the soil and the inner wall of the pipeline, which is not conducive to the smooth transportation of the soil in the pipeline, thereby reducing the transportation length of the soil. [0003] At present, the pipeline earth movement technology cannot be practically app...

AI Technical Summary

Problems solved by technology

During the transportation of soil, there is often a lot of friction between the soil and the inner wall of the pipeline, which is not conducive to the smooth transportation of the soil in the pipeline, thus reducing the transportation length of the soil

[0003] At present, the pipeline soil transportation technology cannot be practically applied in the industry because the huge friction force generated by the soil running in the pipeline cannot be effectively solved.

More and more construction projects located in the center of the city have limited foundation soil excavation and transportation conditions. The conventional excavation and transportation methods can no longer meet the actual needs, which affects the specific implementation of many projects.
