Description

Rapidly biodegradable emulsified oil for hydraulic support and preparation method thereof
Technical Field
The application relates to an emulsified oil for a hydraulic support capable of being rapidly biodegraded and a preparation method thereof, and relates to C10M, in particular to the field of mixtures of base materials and additives.
Background
China is a large country of coal, the coal reserves are rich, and large hydraulic support equipment is widely applied under mines during coal exploitation. The transmission medium of the hydraulic support is mainly concentrated solution or emulsified oil, and is mixed with water according to a specified proportion when in use, and the transmission medium can leak to a certain extent due to the problems of machine corrosion, sealing material abrasion and the like in the use process, and can pollute the environment. The common base oil in the emulsion is mineral oil, and is prepared by adding petroleum sodium sulfonate and ethylenediamine tetraacetate, mixing and blending, is not easy to decompose in the environment after leakage, has a certain accumulation tendency, and pollutes underground water in the mine environment. The concentrated solution does not contain base oil and lipophilic surfactant, but the concentrated solution without the base oil has poor lubricating property and rust resistance to hydraulic equipment, can cause rapid abrasion to the equipment, causes abnormal leakage of transmission media, and can also cause safety accidents due to pressure loss caused by the abnormal leakage, reduce the reliability of the equipment and shorten the service life of the equipment.
The application of China patent No. CN2015114086. X discloses an emulsified oil for a synthetic hydraulic support and a preparation method thereof, wherein the emulsified oil is prepared by respectively synthesizing a complex of sodium heavy alkylbenzenesulfonate, oleic acid and triethanolamine, and a complex of alkylphenol and ethylene oxide, and then reacting at normal temperature and normal pressure, so that the problem of environmental pollution caused by a rosin potassium soap heating production process is solved, but the base oil is mineral oil, and the environment is also damaged after leakage. Chinese patent No. CN201611153158.8 discloses a fully synthetic concentrated solution for hydraulic support and its preparation method, which gives up the use of mineral oil, and is easy to degrade after leakage, but the prepared concentrated solution has poor lubrication and rust-proof properties, which affects the long-term stable use of the equipment.
