Description

Technical Field

[0001] The invention relates to the technical field of hydraulic lubricants, and in particular to a high-pressure anti-wear and anti-flammability hydraulic oil composition for a baler. Background Art

[0002] The fully automatic hydraulic bar baler is a key equipment for the finishing and packaging of steel enterprises' products. It can bundle steel into shape for easy transportation and storage. It is a high-tech product that integrates mechanics, hydraulics, electronics, and computer control. The baler needs to use high-pressure anti-wear hydraulic oil during operation.

[0003] As countries around the world pay more attention to environmental protection, various environmental protection laws and regulations are becoming more and more stringent. Some developed countries such as Europe and the United States have withdrawn relevant laws and regulations in certain oil use areas, and explicitly require the use of biodegradable lubricants.

[0004] Fatty acid esters are the latest developed fire-resistant hydraulic oils. Due to their excellent lubricity, high and low temperature stability, outstanding biodegradability, good air release, rubber adaptability and full compatibility with mineral oils, they will gradually replace phosphate fire-resistant fluids. They will be widely used in new areas that attach importance to environmental protection and fire prevention, such as underground excavators, continuous casting production lines, modern agricultural machinery, and marine facilities.

[0005] However, the existing hydraulic oil has a relatively simple composition, and its high pressure resistance and anti-wear ability are relatively poor, thus limiting the use effect of the hydraulic oil. Summary of the invention
