Abstract

The invention discloses a biodegradable hydraulic oil composition which comprises, in weight percent, 5-15% of phenol antioxidants, 1-5% of amine antioxidants, 1-10% of P-type nonmetal extreme pressure anti-wear additives, 5-15% of S-P-type nonmetal extreme pressure anti-wear additives, 3-9% of ashless detergent dispersants, 2-3% of ester antirust agents, 1-5% of calcium sulfonate antirust agents,11-19% of organic metal passivators, 5-7% of ester base oil, 3-5% of lauroyl diethanolamide, 3-5% of butyl methacrylate, 1-5% of petroleum calcium sulfonate, 5-10% of sodium sulfosuccinate, 1-1.5% ofdi-iso-octyldiphenylamine, 4-5% of demulsifiers and 2-4% of ethylenediamine tetraacetic acid. Biodegradable hydraulic oil has prominent biodegradability, excellent oxidation stability and good viscosity-temperature performance, low-temperature performance, anti-foaming performance, anticorrosion antirust performance and anti-wear performance.

Description

technical field [0001] The invention is a formula of biodegradable hydraulic oil. Background technique [0002] Biodegradable hydraulic oil requires the oil to meet the performance requirements of the hydraulic system, and at the same time, its own and loss products have ecological effects, including biodegradability, non-toxicity, ecotoxicity and renewable characteristics; based on the above properties Requirements, biodegradable base oils such as vegetable oil, ester oil, and polyethylene glycol are mainly used in the development process of biodegradable hydraulic oil at present; although the above base oils have good biodegradability, they also have some shortcomings. Such as oxidation stability, insufficient hydrolysis safety, etc. Therefore, how to solve the contradiction between oil biodegradation characteristics and oxidation stability, so that oil products have both the above characteristics has become the focus of researchers.
