Description

A kind of ashless antiwear hydraulic lubricant oil composition and preparation method thereof
Technical field
The invention belongs to chemical technology field, and in particular to for the lubricant oil composite used in Hydraulic Power Transmission System, especially It is related to a kind of ashless antiwear hydraulic lubricant oil composition.
Background technology
Hydraulic oil is exactly the hydraulic medium used using the hydraulic system of liquid pressure energy, and energy is played in hydraulic system Transmission, system lubrication, anti-corrosion, antirust, cooling etc. act on.Hydraulic oil can be generally divided into normal hydraulic oil, antiwear hydraulic oil, low Warm hydraulic oil, fire resistant hydraulic oil, peace and quiet hydraulic oil, green hydraulic oil（The Research Work On Bio-degradable Hydraulic Oil）Etc. kind, wherein usage amount It is maximum for antiwear hydraulic oil.
Antiwear hydraulic oil, which can be divided into, grey type（ZDDP types）With two kinds of Ashless type.There is grey type antiwear hydraulic oil to have fine Wear resistence, the requirement of vane pump can be met.But when with plunger pump, ZDDP can cause corruption to the copper part of plunger pump Erosion, so as to cause the abrasion of Plunger Pump Shaft, swash plate rupture.Further, since ZDDP heat endurance is poor, transported in high-pressure hydraulic Greasy filth is easily produced in row, filter screen is blocked, causes hydraulic system operation failure.At the end of the seventies in last century, American-European joint development A kind of EP agent containing S/P but the Zinc-free high pressure anti-wear hydraulic without ZDDP and tenor are ashless less than 0.01% Antiwear hydraulic oil.Ashless anti-wear hydraulic oil is in hydrolysis stability, demulsification resistance, the filtrability of oil product and heat, oxidation stability side Face is better than antiwear hydraulic oil containing zinc, and its performance standard is equivalent to Denison HF-0.
Recent year is also studied ashless anti-wear hydraulic oil, as CN102399612, CN102719299 are disclosed Zinc-free high pressure anti-wear hydraulic, but add the detergent-dispersant additive containing calcium salt in the hydraulic oil.
The content of the invention
Based on the deficiency of above-mentioned present situation, it is an object of the invention to provide a kind of a kind of higher ashless wear-resistant liquid of combination property Pressure lubricating fluid composition, good greasy property and Oxidation Stability are made it have, extend hydraulic oil and Hydraulic Elements use Life-span；Number of changing oil is reduced simultaneously, improves the operating efficiency of hydraulic machinery, reaches the purpose of energy-conserving and environment-protective.
To achieve the above object, each additive component in compositions of additives is selected meticulously.It is each except considering The component function additive performance of itself and it is prominent the advantages of outside, while using oxidation stability, heat endurance and wear resistence as One of top-priority condition.Therefore, only by additive each component performance also far from realizing above-mentioned purpose, it is necessary to group The performance between each additive component in compound is balanced investigation, and two or more is selected particular against oxygen agent, antiwear additive Different compounds, just allowing for and be easy to implement above-mentioned " balance ".
