Problems solved by technology

Due to the particularity of the working environment of steam turbine oil, it is very easy to produce emulsification. After emulsification, the oil quality will deteriorate and many basic functions will be lost, such as the deterioration of anti-oxidation performance, the increase of acid value, and the loss of lubrication, speed regulation and cooling.
At the same time, oil sludge will be generated, which will cause equipment failure, bring great harm to the equipment, and even cause tile burning.

Abstract

The invention discloses an efficient lubricating oil demulsifier. The efficient lubricating oil demulsifier comprises the following raw materials in parts by weight: 3 to 5 parts of a cationic demulsifier, 0.4 to 0.6 part of vegetable oil-based fatty acid methyl ester, 0.1 to 0.2 part of methyl silicone oil, 0.2 to 0.5 part of phosphate and 1 to 2 parts of ethylene glycol phenyl ether. The efficient lubricating oil demulsifier is obtained by fully mixing the cationic demulsifier, the plant oil-based fatty acid methyl ester, the methyl silicone oil, the phosphate and the ethylene glycol monophenyl ether. The demulsifier disclosed by the invention is obvious in demulsification effect and easy to produce and prepare.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a high-efficiency lubricating oil demulsifier and a production method thereof. Background technique [0002] Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils. Mineral base oils are widely used and used in large quantities. Mineral base oils are refined from crude oil. The main production processes of lubricating oil base oil are: atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or hydrogenation supplementary refinin...
