Problems solved by technology

Synthetic oil is produced to cope with the environment that mineral oil cannot bear. It has better oxidation resistance than mineral oil, resistance to cold and heat, radiation resistance, and is not easy to corrode rubber oil seals. VI viscosity index is higher, so Long lifespan, the disadvantage is that the price is very expensive

Abstract

The present invention discloses lubricating oil for drive chains of locomotives and a method for preparing the same, and belongs to the technical field of lubricating oil. The lubricating oil consists of the following components in parts by weight: 30-50 parts of compound base oil, 10-20 parts of sulfide whale oil, 2-10 parts of graphene modified by sulfhydryl, 5-20 parts of polytetrafluoroethylene particles, 2-5 parts of 2,6-di-tertbutyl-4-methylphenol, 5-15 parts of zinc naphtenate, 1-3 parts of polyisobutylene, and 1-12 parts of monoethanolamine. The lubricating oil for drive chains of locomotives are simple in components, low in cost, better in viscosity index and high in wear resistance. The lubricating oil has a long service life. The steps of the method for preparing the lubricating oil are simple, environmentally friendly, and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to a lubricating oil for a locomotive transmission chain and a preparation method thereof. Background technique [0002] The composition of the existing chain oil is mainly base oil + additives. According to the difference of each chain oil, the base oil accounts for about 85-100%, and the additive accounts for about 0-15%. Base oils can be divided into two categories: 1 mineral oils and 2 synthetic oils. Mineral oil is the product of refining crude oil. The more complicated the refining process is, the more complete the removal of unsaturated hydrocarbons and nitrogen and sulfur will be, and the stability of mineral oil will be higher, but the price will be higher. Synthetic oil is produced to cope with the environment that mineral oil cannot bear. It has better oxidation resistance than mineral oil, resistance to cold and heat, radiation resistance, and is not easy to cor...
