Composition for lubricating oil production and preparation method thereof

Abstract

The invention relates to the technical field of lubricating oil compositions and preparation methods thereof, and discloses a composition for lubricating oil production. The composition comprises the following raw materials in parts by weight: 100-150 parts of base oil, 10-15 parts of a detergent dispersant, 5-10 parts of a viscosity index improver, 10-15 parts of a pour point depressant, 10-15 parts of an antioxidant, 7-9 parts of a friction moderator, 5-8 parts of an oiliness agent, 12-15 parts of an extreme pressure agent, 10-15 parts of an anti-foaming agent, 5-15 parts of a metal deactivator, 5-8 parts of an emulsifier, 7-9 parts of an anticorrosive agent, 10-15 parts of an antirust agent and 12-15 parts of a demulsifier. According to the composition for lubricating oil production and the preparation method thereof, the overall stability is good, the storage stability is good, the storage stability is improved by at least 10%, the problem that the performance of an oil product is changed and the performance exertion of the oil product in the using process is affected due to precipitation of an additive is avoided, and the composition is convenient to use. The lubricating oil composition is prepared through four steps, the stability of the prepared lubricating oil composition is further improved, and meanwhile the preparation method is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of lubricating oil compositions and preparation methods thereof, in particular to a composition used for lubricating oil production 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. It mainly plays the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil It is a technology-intensive product, a mixture of complex hydrocarbons, and its real performance is the combined effect of complex physical or chemical changes. The basic properties of lubricating oil include general physical and chemical properties, special physical and chemical properties and simulation Bench test. [0003] Lubricating oil is generally composed of base oil and additives. Base oil is the main compone...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a composition for lubricating oil production and its preparation method, which has the advantages of convenient storage and solves the problem that after lubricating oil leaves the factory, the oil often needs to be packed in bulk or in barrels. It is put into use after being stored for a period of time, and when many additives are added to heavy base oil, storage stability problems will inevitably occur. If the storage stability is not good, it is easy to precipitate additives, resulting in changes in oil performance, thereby affecting oil quality. The performance of the product during use, the formula composition of the lubricating oil, the storage environment and the storage method all have an impact on the storage stability of the oil
