Abstract

The invention discloses novel ashless wear-resistant hydraulic oil prepared from the following raw materials in parts by weight: 20-40 parts of base oil, 2-6 parts of dodecenylsuccinic acid, 4-8 parts of polymethacrylate, 2-6 parts of methyl silicone grease, 8-16 parts of triphenyl-thiophosphate, 7-14 parts of alkyl diphenylamine, 3-9 parts of alkyl phenyl propionate, 5-10 parts of a carboxylate derivative, 3-7 parts of a benzotriazole fatty acid amine salt, 7-11 parts of isopropyl palmitate, 5-8 parts of sulfide polyisobutylene and 3-6 parts of tert-butyl phenol. The novel ashless wear-resistant hydraulic oil provided by the invention is good in hydrolysis stability, demulsibility, oil product filterability and thermal oxidation stability and longer in service life.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil, in particular to a novel ashless anti-wear hydraulic oil. Background technique [0002] Hydraulic oil is the hydraulic medium used in the hydraulic system that utilizes liquid pressure energy. It plays the role of energy transmission, system lubrication, anti-corrosion, rust prevention, cooling, etc. in the hydraulic system. For hydraulic oil, it should first meet the requirements of the hydraulic device on the viscosity of the liquid at the working temperature and the starting temperature. Since the viscosity change of the oil is directly related to the hydraulic action, transmission efficiency and transmission accuracy, the viscosity-temperature performance of the oil and the Shear stability should meet the various needs raised by different uses. There are many kinds of hydraulic oils, and the classification methods are different. For a long time, it is customary to classify them by use,...
