Abstract

The present invention provides a kind of hoisting machinery hydraulic oil and preparation method thereof, is prepared by following component：Polyurethane, dioctyl phthalate, nano-bentonite, modified calcium carbonate, nano-titanium dioxide, zircon powder, 32NS three classes hydrogenated base oil, poly alpha olefine synthetic oil, algal oil, viscosity modifier, squeezes antiwear additive, antioxidant, polyalcohol, paraffin, defoaming agent, Ca-Zn composite thermal stabilizer, dispersing agent and lubricant at natural gum extract.It is of the invention that preparation method is simple, cost of manufacture is cheap, is suitable for the hydraulic oil making technology of mass production, and the hydraulic oil of preparation has good anti-wear, wettability, Oxidation Stability, the service life for extending hydraulic oil and Hydraulic Elements improves the working efficiency of hydraulic machinery.

Description

A kind of hoisting machinery hydraulic oil and preparation method thereof
Technical field
The invention belongs to hydraulic oil technical fields, and in particular to a kind of hoisting machinery hydraulic oil and preparation method thereof.
Background technique
There are many mechanical type, wherein such as excavator, loading machine, crane, agitator truck, these mechanical equipments General field work severe in natural environment all the year round requires to carry out necessary work by hydraulic pressure transfer system.Hydraulic oil An important component of hydraulic technique, in hydraulic system it can play energy transmission, system lubrication, anti-corrosion, antirust, The effects of cooling.With the continuous development of hydraulic system technology, precision element using more and more extensive, such as accurate filter Deng the quality requirement for the work well for ensuring precision instrument, thus hydraulic system oil is also gradually increased.It is required that hydraulic oil is answered This has adaptability, the filterability of good viscous warm nature, wear resistence, hydrolysis stability and associated materials, especially thermostabilization Property and oxidation stability to get well, have good cleannes to ensure hydraulic oil in use, to meet the liquid that increasingly updates Press system oil requirement.
Antiwear hydraulic oil, which can be divided into, has grey type and without zinc-type.There is grey type antiwear hydraulic oil that there is good wear resistence, energy Meet the requirement of vane pump.But when for column match pump, there is grey type antiwear hydraulic oil that can cause to the copper part of plunger pump Corrosion, so as to cause the abrasion of plunger foot, swash plate rupture.Further, since having the thermal stability of grey type poor, in high pressure liquid system operatio Failure.Non-zinc anti-wear hydraulic oils are better than in terms of hydrolysis stability, demulsification resistance, filterability, thermal stability and oxidation stability Antiwear hydraulic oil containing zinc.
With the development and the exploitation of use and the mankind to ruthless area on a large scale of hydraulic machinery, hydraulic pressure system System will face test more from working environment, therefore requirement of the hydraulic system to hydraulic oil is higher and higher, current hydraulic Oil can not fully meet the demand of hydraulic machinery.
Publication No. CN105820860A discloses a kind of energy conservation project mechanical-hydraulic oil and preparation method thereof, by following The raw material of parts by weight forms：0.2-0.9 parts of tricresyl phosphate, 0.8-1.2 parts of antiwear additive, 4-6 parts of benzotriazole octadecylamine salt, oil Sour glycol ester 2-4 parts, 75-85 parts of hydrogenated styrene isoprene copolymer, 1.5-2.5 parts of mono alkenyl succimide, 2, 1.5-2.5 parts of 5- di-tert-butyl hydroquinone, 2.5-3.5 parts of 4,4'- dioctyl diphenylamine, 4-8 parts of polymethacrylates, two 0.02-0.04 parts of methyl-silicone oil, 850-950 parts of base oil.It is wear-resistant to disclose a kind of high-performance by Publication No. CN104845712A Hydraulic oil and preparation method thereof, the hydraulic oil include following components：It is base oil, viscosity modifier, extreme pressure anti-wear additives, anti-oxidant Agent, metal deactivator, lubricant, anti-foaming agent, wherein base oil includes following components：32N three classes hydrogenated base oil, 32NS three classes Hydrogenated base oil, dioctyl phthalate, poly alpha olefine synthetic oil.The above prior art has viscosity index (VI) lower, viscous warm Performance is poor, oxidation stability difference disadvantage, and raw material are excessive and price is not cheap, increase preparation cost, make it not It can promote the use of.
In summary, it is therefore desirable to better hydraulic oil, to improve the deficiencies in the prior art, to push the hair of the sector Exhibition.
Summary of the invention
The object of the present invention is to provide a kind of hoisting machinery hydraulic oil and preparation method thereof, preparation method letter of the invention Single easy, cost of manufacture is cheap, is suitable for the hydraulic oil making technology of mass production, the hydraulic oil of preparation have it is good resist it is wear-resisting Property, wettability, Oxidation Stability, extend the service life of hydraulic oil and Hydraulic Elements, improve the work of hydraulic machinery Make efficiency.
