Efficient wear-resistant lubricating oil and preparation method thereof

Abstract

The invention discloses efficient wear-resistant lubricating oil. The efficient wear-resistant lubricating oil is prepared from components in parts by weight as follows: 40-60 parts of base oil, 30-40 parts of chlorinated paraffin, 20-30 parts of triphenyl phosphate, 10-30 parts of nano-graphite, 10-20 parts of nano-metal oxide, 5-15 parts of nano-aluminum, 3-8 parts of sepiolite, 5-10 parts of mica powder, 2-8 parts of sodium bentonite, 4-10 parts of calcium carbonate, 1-5 parts of an antioxidant, 0.5-3 parts of an antirust agent, 0.4-0.8 parts of an antifoaming agent and 0.2-0.8 parts of a pour point depressant. According to the efficient wear-resistant lubricating oil, defects of poor stability, weak oxidation resistance and poor wear-resistant effect in the prior art can be overcome, the lubricating oil with good stability, high anti-oxidative capacity and remarkable wear-resistant effect is provided, so that mechanical wear is reduced, and service life of machinery is prolonged.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a high-efficiency anti-wear lubricating oil and a preparation method thereof. Background technique [0002] Construction machinery is an important part of China's equipment industry. In a nutshell, all the mechanical equipment necessary for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and loading and unloading operations, and various construction projects are called construction machinery. The working environment of construction machinery is relatively harsh, and the construction period is relatively long. They often work under high temperature and high load conditions, and lubricating oil is essential. [0003] Although the existing lubricating oil for construction machinery can reduce the amount of sludge generated during engine use, it cannot prevent engine wear, ...

AI Technical Summary

Problems solved by technology

[0003] Although the existing lubricating oil for construction machinery can reduce the amount of sludge generated during engine use, it cannot prevent engine wear, stability, and oxidation resistance. It cannot meet the long-term operation of construction machinery in the field and complex working conditions , heavy heat load, frequent oil change and other requirements

[0004] In the process of realizing the present invention, the inventors found that there are at least defects such as poor stability, weak anti-oxidation ability and poor anti-wear effect in the prior art
