Abstract
The present invention relates to a kind of graphene antiwear hydraulic oils, and based on parts by weight, raw material composition is as follows: base oil: 90-98 parts；Antioxidant: 0.1-5 parts；Modified graphene oxide: 1-5 parts；Antirust agent: 0.1-5 parts；Anti-foaming agent: 0.001-0.1 parts.The present invention solves graphene in the dispersion performance of base oil, and acquisition high stability, antifriction antiwear effect are significantly better than the graphene hydraulic oil of traditional antiwear hydraulic oil.
Description
Technical field
The present invention relates to a kind of graphene antiwear hydraulic oils, belong to technical field of lubricating oil.
Background technique
Antiwear hydraulic oil used at present uses the abrasion resistant extreme-pressure addition of sulfur-bearing, phosphorous, phosphorus-nitrogen containing, sulfur-bearing phosphorus nitrogen
Agent, and these additives are larger to environment and health effect, antiwear and friction reduction property is sometimes bad, and requirement is not achieved.Meanwhile
These additives consume very fast (chemical change occurs in friction process) in use, so that the antiwear and antifriction period is shorter.
Summary of the invention
The object of the present invention is to provide a kind of graphene antiwear hydraulic oils, solve graphene in the dispersibility of base oil
Can, acquisition high stability, antifriction antiwear effect are significantly better than the graphene hydraulic oil of traditional antiwear hydraulic oil.
Graphene antiwear hydraulic oil of the present invention, based on parts by weight, raw material composition are as follows:
Base oil: 90-98 parts
Antioxidant: 0.1-5 parts
Modified graphene oxide: 1-5 parts
Antirust agent: 0.1-5 parts
Anti-foaming agent: 0.001-0.1 parts.
Wherein,
Base oil is 150N.
Antioxidant is T531.
Antirust agent is T705, T746.
Anti-foaming agent is T901.
Since modified graphene oxide additive has chemical inertness, will not chemically react in use, because
This modified graphene oxide component will not be too fast consume, be conducive to keep the long-term antiwear and friction reduction property of hydraulic oil.
Due to the outstanding heating conduction that also there is modified graphene general bucket hydraulic oil not have, graphene liquid of the invention
Pressure oil thermal coefficient with higher, the heat that can be generated in cracking release system, makes hydraulic system in lower use
At a temperature of work, therefore have better equipment protection performance, the service life of hydraulic system equipment can be extended, reduce use and dimension
Protect cost.
Compared with prior art, the present invention just have it is following the utility model has the advantages that
Reduce the type of additives in raw materials: common antiwear hydraulic oil is by base oil, antioxidant, antiwear additive, antifriction
The additives such as agent, extreme pressure agent, demulsifying agent, anti-foaming agent, dispersing agent, antirust agent and matal deactivator composition.Formula of the invention
Due to having used modified graphene oxide, polarity is smaller compared with common additives, with outstanding abrasion resistant extreme-pressure performance and subtracts
It rubs performance, the advantages that had no corrosive effect on metals, reduces additive types, simplify formula.
Specific embodiment
The present invention will be further explained with reference to the examples below.

Anti-foaming agent: 0.1 part.
Embodiment 2
Graphene antiwear hydraulic oil of the present invention, based on parts by weight, raw material composition are as follows:
Base oil: 98 parts
Antioxidant: 0.1 part
Modified graphene oxide: 1 part
Antirust agent: 0.1 part
Anti-foaming agent: 0.1 part.
Embodiment 3
Graphene antiwear hydraulic oil of the present invention, based on parts by weight, raw material composition are as follows:
Base oil: 95 parts
Antioxidant: 3 parts
