Abstract

The invention discloses a production process of environment-friendly type hydraulic oil, and relates to the technical field of hydraulic system accessories. The production process of the environment-friendly type hydraulic oil comprises the following steps: first, preparing materials; second, mixing and preheating; third, heating; fourth, cooling, filtering and distilling, namely, placing the mixture in the third step into a refrigerating room, decreasing the temperature of the mixture to 15 to 20 DEG C, performing multistage filtering, and placing a clear liquid obtained by filtering into a distilling tank, distilling for 10 to 20 minutes under the pressure of -0.2 to -1 MPa and the temperature of 80 to 100 DEG C, and cooling the distilled liquid to room temperature to obtain finished hydraulic oil. The hydraulic oil prepared by the production process has excellent biodegradability to make up low biodegradability of a dispersing agent or other additives in a formula, and has high lowtemperature performance and high lubricating performance.

Description

technical field [0001] The invention relates to the technical field of hydraulic system accessories, and more specifically relates to a production process of environment-friendly hydraulic oil. Background technique [0002] The environment is the basis for the survival of human beings and other lives. The leakage of the hydraulic system will cause a large amount of hydraulic oil to enter the environment, causing serious pollution. Therefore, the development of biodegradable hydraulic oil has received great attention. Biodegradable hydraulic oil has also It is called environmentally friendly hydraulic oil, which means that the oil must meet the performance requirements of the hydraulic system, and its own and consumption products have ecological effects, including: biodegradability, ecotoxicity, and regeneration. [0003] In Europe and North America, the research and application of biodegradable hydraulic oils began to be vigorously promoted more than 20 years ago, especially...
