Abstract

The invention relates to the technical field of concentrated liquid for hydraulic supports, and specifically discloses a graphene oxide graft-modified oleic acid soap, concentrated liquid for hydraulic supports, a preparation method and application thereof. The raw materials of the graphene oxide grafted modified oleic acid soap include graphene oxide, triethanolamine and oleic acid. Applying graphene oxide grafted modified oleic acid soap to the preparation of concentrated liquid for hydraulic support can not only improve the lubricity, anti-corrosion and anti-rust performance of concentrated liquid of hydraulic support, but also significantly improve the freeze-thaw performance and Stable storage performance solves the problems of oil and soap separation, clogged valves, etc., increases the service life of the hydraulic support, greatly reduces maintenance costs, and has high use value and application value.

Description

technical field [0001] The invention relates to the technical field of concentrated liquid for hydraulic supports, in particular to a graphene oxide grafted modified oleic acid soap, concentrated liquid for hydraulic supports, preparation method and application. Background technique [0002] The hydraulic support is an important mechanical equipment used to support the roof in the coal mining face of the coal industry. Its supporting use with the coal shearer not only realizes the comprehensive mechanization of coal mining, improves the efficiency of coal mining and transportation equipment, but also guarantees the safety of the coal mine to the greatest extent. worker's life safety. As the working medium of the hydraulic support, the hydraulic support fluid not only plays the role of power transmission, but also plays the role of lubrication, cooling, anti-corrosion and rust prevention, and is called the "blood" of the hydraulic support system. At present, domestic coal mi...
