Abstract

The invention discloses environment-friendly fully-synthetic bracket hydraulic fluid, which consists of 5 to 8 mass percent of organic amine, 2 to 5 mass percent of organic monocarboxylic acid, 1 to 3 mass percent of organic dicarboxylic acid, 8 to 13 mass percent of hydroxyacetic acid, 0.5 to 1 mass percent of alkali, 0.1 to 0.3 mass percent of corrosion inhibitor, 0.1 to 0.3 mass percent of defoamer and the balance of water. The invention also provides the preparation method of the environment-friendly fully-synthetic bracket hydraulic fluid. The hydraulic fluid does not contain mineral oiland is prepared from polymer, organic acid and other materials, the biodegradability of the hydraulic fluid is high and the influence of the hydraulic fluid on the environment is small.

Description

Technical field: [0001] The invention relates to the field of organic chemistry, in particular to a hydraulic fluid, in particular to an environment-friendly fully synthetic hydraulic fluid for mine hydraulic supports (columns) and a preparation method thereof. Background technique: [0002] Hydraulic support is an important part of fully mechanized mining equipment. It can reliably and effectively support and control the roof of the working face, isolate the goaf, and prevent gangue from entering the mining face and advancing the conveyor. The hydraulic support is used in conjunction with the mining machine to realize the comprehensive mechanization of mining, solve the contradiction that the roof management of the mechanized mining work lags behind the mining work, further improve and improve the efficiency of mining and transportation equipment, reduce the labor intensity of mining workers, and maximize the protection of mining workers life safety. [0003] In recent yea...
