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 provides a complexing agent for industrial hydraulic circulating oil. The complexing agent is composed of base oil, an antioxidant, a rust inhibitor, a metal deactivator, an antiwear additive, a demulsifying agent, a foam inhibitor, a viscosity index improver, borate and alkyl naphthalene, wherein the antioxidant is ashless dialkyl dithiocarbamate; the rust inhibitor is an imidazoline derivative; the metal deactivator is 2-mercaptobenzothiazole; the antiwear additive is metal dialkyldithiocarbamate salt; the demulsifying agent is polyalkoxylated polyol; the foam inhibitor is polydimethylsiloxane; and the viscosity index improver is polyalkyl methacrylate. According to the invention, the manufacturing method is simple and has easy operation; and the prepared product has a price lower than the price of the product of a same kind, has prominent effects, maintains the use effect of hydraulic oil for a long time, and has comprehensive effect higher than the comprehensive effect of the product of a same kind.

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 industrial hydraulic circulating oil compounding agent. [0003] (2) Background technology [0004] At present, hydraulic oil is used in industrial machinery, agricultural machinery, aviation equipment, marine equipment, and automobile industry. 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 extreme pressure resistance; 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 equipmen...
