Problems solved by technology

[0002] The anti-wear hydraulic oils currently used all use anti-wear extreme pressure additives containing sulfur, phosphorus, phosphorus and nitrogen, and sulfur, phosphorus and nitrogen elements. These additives have a greater impact on the environment and health, and sometimes have poor anti-wear and anti-friction properties. , does not meet the requirements for use
At the same time, these additives are consumed quickly during use (chemical changes occur during friction), making the anti-wear and anti-friction cycle shorter

Abstract

The invention relates to graphene absorption-resistant hydraulic oil. The hydraulic oil is prepared from the following raw materials in parts by weight: 90-98 parts of base oil, 0.1-5 parts of antioxidant, 1-5 parts of modified graphene oxide, 0.1-5 parts of an anti-rust agent and 0.001-0.1 part of an antifoaming agent. The graphene abrasion-resistant hydraulic oil can solve the dispersing performance of graphene in base oil, and has high stability and friction-reducing and abrasion-resisting effects greatly superior to those of traditional abrasion-resistant hydraulic oil.

Description

technical field [0001] The invention relates to a graphene anti-wear hydraulic oil, which belongs to the technical field of lubricating oil. Background technique [0002] The anti-wear hydraulic oils currently used all use anti-wear extreme pressure additives containing sulfur, phosphorus, phosphorus and nitrogen, and sulfur, phosphorus and nitrogen elements, and these additives have a greater impact on the environment and health, and the anti-wear and anti-friction properties are sometimes poor. , can not meet the use requirements. At the same time, these additives are consumed quickly during use (chemical changes occur during the friction process), which makes the anti-wear and anti-friction cycle shorter. Contents of the invention [0003] The object of the present invention is to provide a graphene anti-wear hydraulic oil, which solves the dispersion performance of graphene in the base oil, and obtains graphene hydraulic oil with high stability, anti-friction and anti...
