The hydraulic oil of the present invention, has excellent air release property energy, mainly by resisting to viscosity index improver, extreme pressure
What the specific selection of the various auxiliary agents such as grinding agent, preservative and the specific selection of compounding and the dosage of various auxiliary agents were realized.
The hydraulic oil with excellent air release property energy obtained using technical scheme of the present invention, under the conditions of 50 DEG C
Air release value can be as short as 1min even it is shorter, can effectively keep the Incoercibility of hydraulic oil, avoid pressure acute variation
When instrument there is judder.
The second object of the present invention is the preparation method for providing the above-mentioned hydraulic oil with excellent air release property energy, institute
Preparation method is stated to comprise the following steps：
1) base oil is heated to 50 DEG C~70 DEG C in the state of 20-80r/min stirring；
2) viscosity index improver, extreme pressure anti-wear additives, preservative, antioxygen are sequentially added under 20-80r/min stirring condition
Antigum inhibitor, anti-foaming agent, after often adding a kind of additive, need to stir to well mixed can add down a kind of additive, to be added
After constant temperature stirring 3-5 hours.
Further, preparation method of the present invention, preferably described viscosity index improver are polymethacrylates
And/or polyisobutene；The extreme pressure anti-wear additives are boronation thiophosphate amine salt；The preservative is neutral dinonylnaphthalene sulfonic acid
Barium；The antioxidizing and antigum agent is 2,6-di-t-butyl Pyrogentisinic Acid.
The method that hydraulic oil of the present invention with excellent air release property energy makes is simple, viscosity, flash-point, anti-breast
The performance indications such as the property changed can reach the requirement of national standard, is not easy to spume, is a kind of good hydraulic oil of quality, have wide
Application prospect.
