Abstract

The invention provides environment-friendly anti-wear lubricating oil and a preparation method thereof. The environment-friendly anti-wear lubricating oil is prepared from the following components inparts by weight: 5 to 20 parts of base oil, 55 to 85 parts of esterified castor oil, 3 to 18 parts of polyethylene glycol fatty acid ester, 0.1 to 1.5 part of a stabilizing agent, 0.1 to 5 parts of ananti-wear agent and 0.5 to 4 parts of auxiliary additives. The environment-friendly anti-wear lubricating oil and the preparation method thereof have the beneficial effects that the esterified castoroil is added to react on the surface of a metal to form an adsorbing film to achieve the effects of reducing wear and resisting wear; a novel anti-wear agent encapsulates borate / ester in cyclodextrinto avoid the corrosion of the borate to the metal, the anti-wear performance of the novel anti-wear agent is fully played, and the novel anti-wear agent is environmentally friendly and good in anti-wear performance; the anti-wear agent formed by magnesium silicate / talcum powder reacts with the surface of the metal to form a single-layer film of metallic soap, which achieves the effects of reducing the wear and resisting the wear; polyethylene glycol fatty acid ester blends various components to homogenize the components and enhance the anti-oxidation performance and the lubricating performance of the lubricating oil; the lubricating oil prepared by adding the esterified castor oil, the polyethylene glycol fatty acid ester and the novel anti-wear agent is environmentally friendly and goodin anti-wear performance.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, and in particular relates to an environment-friendly anti-wear lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of mechanical equipment and automobiles to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Between two relatively moving objects, it can reduce the friction and wear of the two objects due to contact, that is, lubricating oil. [0003] Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. Lubri...
