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

Abstract

The invention relates to an anti-wear hydraulic oil composite agent, which comprises base oil, an antioxidant, a rust corrosion inhibitor, a metal deactivator, an anti-wear additive, a demulsifier, a foam inhibitor, a viscosity index improver, tungsten hydroxide, ammonium phosphate, poly alkyl methacrylate, and polyisobutylene, wherein the antioxidant is a dialkyl phosphorodithioic acid metal salt, the rust corrosion inhibitor is an imidazoline derivative, the metal deactivator is benzotriazole, the anti-wear additive is alkyl containing phosphate and salt, the demulsifier is polyalkoxy polyol, the foam inhibitor is polydimethylsiloxane, and the viscosity index improver is an olefin copolymer. 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 oil compound. [0003] (2) Background technology [0004] The production of hydraulic oil needs to ensure its long-term and effective comprehensive effect, which must achieve heat transfer; protect and lubricate the various components of the overall system; stably take away heat through circulation; protect each component from oxidation and corrosion; provide good wear protection ; Provides good anti-extreme pressure effect; and good thermal stability and long-term service life. However, the existing hydraulic oil compound additives are not outstanding in efficacy, which is difficult to meet the higher use requirements of various mechanical equipment, and the comprehensive efficacy is not obvious. Moreover, there are fewer and more expensive hydraulic oil compound additive suppliers than engine lubricating...
