Problems solved by technology

However, the production process and technical requirements of lubricating fluids are different from those of other lubricating oils. In the production process of manufacturing fluids, various manufacturers produce different lubricants due to different conditions, different formulas, and different material selections. The quality of the hydraulic fluid produced varies greatly, and some manufacturers only use part of the single agent in order to maximize profits, so the quality of the hydraulic fluid produced is not ideal. In order to protect their various equipment, people meet various The performance requirements of the equipment, while using imported products, but the price is expensive
There are few domestic manufacturers of compound additives that can fully meet the performance requirements of hydraulic fluids, and they cannot achieve the ideal use effect

Abstract

The invention provides anti-rust and stain-free hydraulic fluid. The anti-rust and stain-free hydraulic fluid is characterized by being prepared from synthesized sodium sulfonate, base oil, boric acidester, chlorinated paraffin, polyester, nonylphenol polyoxyethylene ether, ricinoleic acid triethanolamine phosphate, polyether, a surfactant, water, a thickening agent, an anti-rust additive, an anti-wear additive and a scale inhibition corrosion inhibitor. The lubricant ash-free extra pressure anti-wear additive is adopted, and the extra anti-rust additive is added, so that the anti-rust protection capacity of the hydraulic fluid in a closed system is effectively enhanced, and the anti-rust, stain-free and anti-wear requirements in a tiny gap are greatly met; in addition, the thickening agent with the high mechanical shearing resistant capacity is adopted, thus, the stability of mechanical shearing is effectively improved, the strength and thickness of an oil film are effectively increased, and the lubricating performance and extreme pressure performance of the hydraulic fluid are greatly improved; besides, the anti-rust and stain-free hydraulic fluid has high lubricating, cooling,cleaning and rust prevention performance, and has anti-corrosion and anti-wear properties, therefore a hydraulic system can transmit working signals reliably, and the service life of the hydraulic fluid can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of hydraulic fluid, in particular to a rust-proof and stain-free hydraulic fluid. Background technique [0002] At present, with the continuous progress of human society, the continuous updating of various mechanical equipment and the manufacture and production of new equipment, the consumption of hydraulic fluid is nearly 6 times higher than that of 5 years ago. However, the production process and technical requirements of lubricating fluids are different from those of other lubricating oils. In the production process of manufacturing fluids, various manufacturers produce different lubricants due to different conditions, different formulas, and different material selections. The quality of the hydraulic fluid produced varies greatly, and some manufacturers only use part of the single agent in order to maximize profits, so the quality of the hydraulic fluid produced is not ideal. In order to protect their va...
