Problems solved by technology

[0003] The existing anti-wear hydraulic oil is produced in accordance with national standards, and the standard does not include the cleanliness and dispersion of the oil, the wear scar diameter of the anti-wear performance, and the maximum non-jamming load P of the extreme pressure performance. B , comprehensive wear value, etc. put forward specific data requirements, so the quality of hydraulic oil produced in accordance with national standards on the market varies greatly

Embodiment 1

[0034] The components of the hydraulic oil compound formulation are calculated by mass percentage: long-chain primary alcohol dialkyl dithiophosphate zinc 20%, di-tert-butyl-p-cresol 10%, alkylated diphenylamine 10%, tricresyl phosphate Ester 15%, high base number synthetic calcium sulfonate 8%, bispolyisobutylimide 5%, dodecenylsuccinic acid half ester 1%, basic dinonylnaphthalene sulfonate barium 4%, benzene triacetate Azole octadecylamine salt 1.5%, supplemented by low-viscosity second-class base oil. The preparation process is as follows: adding each component into the reaction kettle according to its mass percentage, heating up to 75 DEG C, stirring evenly and cooling.

[0035] The above compound formulation is added to 98% of the second-class base oil by mass percentage of 2%, and the temperature is raised to 55 ℃ in the reactor, stirred evenly and cooled, and the prepared hydraulic oil has high anti-wear performance, and the maximum No jamming load P B At 830N, the we...

Abstract

The invention discloses an anti-wear and anti-oxidation hydraulic oil composite agent formula, comprising the following components in terms of mass percentage: 10-25% of long-chain primary alcohol dialkyl zinc dithiophosphate, 10-25% of di-tert-butyl p-cresol 30%, Alkylated Diphenylamine 0‑15%, Tricresyl Phosphate 10‑25%, Overbase Synthetic Calcium Sulfonate 1‑10%, BisPolyisobutylene Imide 1‑10%, Dodecenyl 0-1% of succinic acid half ester, 1-8% of basic barium dinonyl naphthalene sulfonate, 1-3% of benzotriazole octadecylamine salt, 10-30% of base oil; the invention also discloses a compounding agent The preparation process of the above-mentioned hydraulic oil compound agent is added into the reaction kettle according to the mass percentage of each component in the formula, the temperature is raised to 70-80 ° C, stirred and cooled. The hydraulic oil prepared by combining the compounding agent of the present invention with the base oil has excellent anti-oxidation and anti-corrosion properties and excellent anti-wear properties, and has good cleaning and dispersing properties at the same time.

Description

technical field [0001] The present invention relates to the technical field of lubricating oil. More specifically, the present invention relates to an anti-wear and anti-oxidative hydraulic oil compound formulation and a preparation process thereof. Background technique [0002] Hydraulic oil is an important part of hydraulic technology. It is used in hydraulic system to realize energy conversion, transmission and control. At the same time, it also plays the role of lubrication, anti-rust, anti-corrosion and cooling of the system. People regard the oil pump in the hydraulic system as the heart, and the hydraulic oil is the blood of the system. Hydraulic systems are widely used in various mechanical equipment. Driven by a motor, the hydraulic oil is converted from mechanical energy to pressure energy through a pump. [0003] The existing anti-wear hydraulic oil is produced in accordance with the national standards. In its standard, it does not have the detergency and dispe...
