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 very 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 relates to a compounded agent added to hydraulic fluid. The compounded agent is characterized by being prepared from base oil, an antioxidant, a detergent, a rust inhibitor, a metal deactivator, a demulsifier, a pour point depressant, a foam inhibitor, an anti-wear agent and tungsten oxide. A preparation method is simple and practical, the cost of the prepared product is relatively low, and the effect is higher than that of like products; and due to the formula system, the corrosion resistance, wear resistance, oxidation resistance, thermal stability and demulsibility of the hydraulic fluid can be completely improved, and the service life of the hydraulic fluid can be greatly prolonged.

Description

(1) Technical field [0001] The invention relates to a compound additive for lubricating oil, in particular to a preparation scheme and a manufacturing method of the compound additive added in hydraulic fluid. (2) Background technology [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 5 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 hyd...
