Problems solved by technology

[0003] For gear oils used in sealed gear devices operating in a wide temperature range and under severe conditions of heavy loads and impact loads, the current formulations generally use mineral oils and ordinary gear oil compounds for production. In extreme ambient temperatures and harsh working conditions When used under low conditions, it is impossible to form a strong oil film on the tooth surface, and it is impossible to achieve long-life oil use, which will inevitably lead to micropitting and increased wear on the gear surface
In this case, the gear oil prepared according to the current technology has limited use, and the protection of the gearbox is not enough, and it is prone to burns and gluing

Abstract

The invention provides a nano diamond superheavy gear oil which is composed of the following components in parts by weight: 28-35 parts of metallocene PAO150 basic oil, 20-27 parts of cyclohexane dicarboxylic acid ester, 18-25 parts of alkyl naphthalene, 0.01-0.03 part of nano diamond particle modified by a lipophilic surface, 0.5-1.6 parts of an amine antioxidant, 1-1.6 parts of a viscosity indeximprover,.4-2.6 parts of ashless composite anti-wear reagent at extreme pressure, 1.0-1.6 parts of a repair type friction improver, 0.8-1.3 parts of anti-emulsifying agent, 1.2-1.7 parts of a rust-proof preservative. The nano diamond superheavy gear oil has the advantages that the oil can be used at extreme environment temperature and harsh work conditions, improves extreme pressure anti-wear protection of seal gear oil box, and extends the service lives of the gear and gear oil.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a nano-diamond super-heavy-duty gear 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, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is generally It consists of 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. [0003] For gear oils used in sealed gear devices operating in a wide temperature range and under severe conditions of heavy loads and impact loads, the current formulations generally...
