Abstract

The utility model relates to a composite functional additive of emulsified oil for a hydraulic support and a preparation method of the composite functional additive, and belongs to the technical fieldof hydraulic transmission media for coal mining equipment. Water, castor oil, potassium hydroxide, oleic acid, triethanolamine, ethylene glycol, triethylene glycol monobutyl ether, ether carboxylic acid, sorbitan oleate, benzotriazole and the like are used as raw materials and reacted at certain temperature under normal pressure to obtain the composite functional additive. In addition, the composite functional additive has corrosion inhibition property, lubricating property, sealing material compatibility, high and low temperature resistance, hard water resistance, low temperature reduction resistance and good solubility in the base oil 70SN.

Description

technical field [0001] The invention relates to a composite functional additive for emulsified oil used in hydraulic supports and a preparation method thereof, belonging to the technical field of hydraulic transmission media for coal mining equipment. Background technique [0002] In recent years, with the continuous improvement of coal mining technology and the modernization of coal mining equipment, the hydraulic support is also developing in the direction of large working resistance, large mining height, and electro-hydraulic control, which puts forward higher requirements for the hydraulic transmission medium of the hydraulic support. Require. The hydraulic transmission medium with high stability, high lubricity and high adaptability to coal mine water quality is crucial to the stability and reliability of hydraulic support operation; it is essential to ensure safe production and normal operation of coal mine underground, high yield and high efficiency, and reduce produc...
