Abstract

The invention discloses a lubricating oil composition with an anti-rust function. The lubricating oil composition comprises the following raw materials: base oil, an ethylene-propylene copolymer, trimethylolpropane oleate, triethanolamine oleate, modified graphene oxide, alkyl naphthalene, polymethacrylate, dimethoxyethane, tetralin and zinc dialkyl dithiophosphate. The invention also discloses apreparation method for the lubricating oil composition with the anti-rust function. The lubricating oil composition prepared by using the preparation method provided by the invention has the followingadvantages: excellent anti-rust performance is achieved; through ultrasonic wave and microwave combined effects, the mixing effect of materials is effectively improved, so the anti-rust performance of lubricating oil is further improved; meanwhile, through mutual cooperation of the modified graphene oxide and the zinc dialkyl dithiophosphate, a synergistic effect is exerted, so the anti-rust effect of the lubricating oil can be effectively improved; and the lubricating oil composition has broad market prospects.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a lubricating oil composition with antirust function and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Lubricating oil can lubricate processing equipment and components, assist cooling, rust prevention, cleaning, sealing and buffering. With the application and development of various metal processing technologies such as copper and iron, new requirements are put forward for the lubricating performance of processing equipment and components, especially the antirust performance. However, the traditional lubricating oil often has outstanding lubricating effect, but does not have a good antirust effect, which causes a large number of equipment to be scrapped due to rust and corrosion durin...
