Problems solved by technology

However, the existing composite additives for hydraulic oils are not effective, and it is difficult to meet the higher requirements of various mechanical equipment, and the comprehensive effect is not obvious.
Moreover, there are fewer suppliers of compound additives for hydraulic oil than suppliers of compound additives for engine lubricating oil, and the price is expensive. Many lubricating oil manufacturers basically use several single-agent blends to produce hydraulic oil. The reduction in production costs will inevitably make The produced hydraulic oil has poor efficacy, short service life and unsatisfactory overall efficacy

According to the present invention, the production method is simple, the operation is easy, the price of the prepared product is lower than the price of the similar products, various effects of the prepared product are outstanding, the use effects of the hydraulic oil are maintained for a long time, and the comprehensive effect of the prepared product is higher than the comprehensive effect of other similar products.

Description

[0001] (1) Technical field [0002] The invention relates to a lubricating oil additive, in particular to a preparation scheme and a manufacturing method of an anti-wear hydraulic fluid additive. [0003] (2) Background technology [0004] The production of hydraulic oil needs to ensure its long-term effective comprehensive effect, and must achieve heat transfer; protect and lubricate the various components of the overall system; stably remove heat through circulation; protect various components from oxidation and corrosion; provide good wear protection ; Provide good anti-extreme pressure effect; and good thermal stability and long service life. However, the existing composite additives for hydraulic oil have not outstanding effects, and it is difficult to meet the higher requirements of various mechanical equipment, and the comprehensive effect is not obvious. Moreover, there are fewer suppliers of compound additives for hydraulic oil than suppliers of compound additives for...
