Abstract

The invention provides a biodegraded plant oil based hydraulic oil composition, and comprises the following components in percentages by weight: 2-6% of a hydraulic oil complexing agent, 0.1-0.3% of an anti-oxidant, 0.005-0.015% of an anti-foaming agent, and the balance being natural plant oil. The biodegraded plant oil based hydraulic oil composition uses the natural plant oil as base oil, a plurality of functional additives such as the anti-oxidant, the anti-foaming agent and the hydraulic oil complexing agent are used for optimization and compatibility, and the composition is suitable for lubrication and sealing of hydraulic systems of various equipments with environmental protection requirements or biodegradable requirements.

Description

technical field [0001] The invention relates to a hydraulic oil composition, in particular to a vegetable oil-based hydraulic oil composition, which is suitable for lubricating and sealing the hydraulic systems of various equipment with environmental requirements or biodegradable requirements. Background technique [0002] Mineral oil-based hydraulic oil has poor biodegradability and high biotoxicity, and once leaked, it will cause harm to human body and environment. With the gradual strengthening of people's awareness of green environmental protection and the increasingly stringent environmental protection laws and regulations, the pollution and damage of hydraulic oil to the environment has attracted the attention of various countries. -2011, this specification is one of the quality standards for biodegradable hydraulic oil recognized by countries all over the world. Therefore, the development of biodegradable hydraulic oil has received great attention. Biodegradable hyd...
