Description

technical field [0001] The invention belongs to the technical field of hydraulic equipment, and relates to a hydraulic oil, in particular to a high-viscosity low-temperature hydraulic oil and a preparation process thereof. Background technique [0002] The environment is the foundation upon which human beings and other life depend. Leakage of the hydraulic system, a large amount of hydraulic oil into the environment, causing serious pollution. Therefore, the development of biodegradable hydraulic oil has received great attention. Biodegradable hydraulic oil is also known as environmentally friendly hydraulic oil, which means that the oil must meet the performance requirements of the hydraulic system, and its own and the consumption products have ecological effects, including: biodegradability, ecotoxicity, regeneration, etc. . [0003] The environmental characteristics of marine hydraulic machinery determine that marine hydraulic oil should have good viscosity-temperature...
