Problems solved by technology

The existing emulsified oil production mainly includes two formulations of naphthenic acid and rosin. The naphthenic acid formulation uses sodium naphthenate as the main surfactant, and sodium naphthenate is refined from petroleum (mainly naphthenic crude oil) The naphthenic acid obtained in the process is refined and then neutralized with sodium hydroxide. With the improvement and improvement of the oil refining process, the output of naphthenic acid is getting lower and lower, and the resources are seriously depleted, which has become a problem affecting the production of emulsified oil. The main obstacle; the rosin formula selects anionic rosin potassium soap as the main surfactant. Although the raw material is easy to get, the production process of rosin potassium soap is carried out by heating. In the production process, volatile organic compounds are easy to stimulate the human respiratory tract and pollute Environment, and the produced emulsified oil has poor anti-oxidation stability, darker color, and the lubricity of the emulsion is worse than that of the emulsified oil produced by sodium naphthenate

Abstract

The invention discloses synthetic emulsified oil used for hydraulic supports and a preparation method thereof. The emulsified oil comprises the following components by weight percent: 30-35% of 7# base oil, 20-22% of sodium heavy alkylbenzene sulfonate, 10-13% of compound of oleic acid and triethanolamine, 5-7% of complex of alkylphenol and ethylene oxide, 3-4% of triethanolamine, 0.1-0.2% of benzotriazole, 1-1.5% of coconut fatty acid diethanol amide, 0.4-0.8% of zinc naphthenate and the balance of distilled water. The method is characterized by firstly synthesizing sodium heavy alkylbenzene sulfonate, the compound of oleic acid and triethanolamine and the complex of alkylphenol and ethylene oxide respectively, then adding the raw materials to a reaction kettle in sequence at normal temperature and pressure, stirring the materials uniformly and putting the mixture in a bucket after the mixture passes inspection. The emulsified oil and the preparation method have the beneficial effects that the selected raw materials have wide sources; the process is simple; the emulsified oil has good freeze-thaw resistance, lubricating property and emulsifying stability; the problems of oil perspiring and soap graining are effectively reduced; filter screens are not blocked.
