Problems solved by technology

[0003] At present, most traditional lubricating oils use mineral base oils, which have strong accumulation of ecological toxicity and poor biodegradability. A large amount of harmful substances will be produced in the process of preparation and use, which is very easy to pollute the environment. A small part of lubricating oils use vegetable base oils , although it is non-toxic and easy to degrade, it has poor oxidation stability, high viscosity, low fluidity and easy solidification at low temperature, which inevitably increases the energy consumption of lubricating oil, produces a certain waste of resources, and reduces the lubricating effect of lubricating oil

Abstract

The invention discloses environment-friendly high-fluidity lubricating oil and a preparation method thereof. The formula comprises environment-friendly base oil, a flow modifier, high-base-number sulfurized calcium alkyl phenolate, allyl mercaptan, dimercaptothiadiazole, thiophosphate secondary alkyl zinc salt and fatty alcohol-polyoxyethylene ether. The lubricating oil comprises the following components in parts by weight: 185-245 parts of environment-friendly base oil, 6-10 parts of a flow modifier, 7-9 parts of high-base-number sulfurized calcium alkyl phenolate, 4-6 parts of allyl mercaptan, 3-5 parts of dimercaptothiadiazole, 1-3 parts of thiophosphate secondary alkyl zinc salt and 1-3 parts of fatty alcohol-polyoxyethylene ether. The environment-friendly base oil prepared from the high oleic acid vegetable oil, the ethylene glycol, the potassium hydroxide and the isoprene is adopted to replace traditional mineral base oil and plant base oil, the oxidation stability of the lubricating oil is improved, no toxicity or harm is generated in the preparation and use process, biodegradation is easy in the natural environment, and pollution to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to an environment-friendly and high-fluidity lubricating oil 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 roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. In a broad sense, as long as it is applied between two relatively moving objects and can reduce the friction and wear of the two objects due to the function of contact, it is a lubricant. 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...
