Friction improver with nano mesoporous carbon and preparation method of friction improver

Abstract

The invention relates to the technical field of nano materials and in particular relates to a friction improver with nano mesoporous carbon and a preparation method of the friction improver. The preparation method comprises the following steps: firstly, preparing nano artificial graphite particles from basic oil, a part of an ashless dispersant and nano artificial graphite, mixing with other components, carrying out ultrasonic dispersion on the mixture, and further stirring by using a stirring machine. As dispersion coating treatment on nano mesoporous carbon and the nano artificial graphite is implemented, good dispersibility can be achieved in the basic oil and lubricating oil, long-term suspension can be achieved, no settlement is resulted, oil paths are not blocked, good thermal stability and abrasion reduction effects are achieved, the friction improver can be fused with various types of lubricating oil and has high temperatures, high speeds and high loads, carbon accumulation canbe avoided, the lubrication performance of metallic components of an engine can be greatly improved, an effective physical adsorption protection membrane and a chemical reaction protection membrane can be formed, high abrasion of components of the engine can be alleviated, and the service life of the engine can be prolonged.

Description

technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a friction modifier containing nanometer mesoporous carbon and a preparation method thereof. Background technique [0002] Since the beginning of the 21st century, the number of automobiles in my country has grown rapidly, and regulations and standards related to automobile safety, environmental protection, and energy conservation have been increasingly strengthened, which has promoted the continuous improvement of vehicle engine power, economy, and emission characteristics. Among them, the automobile engine lubricating oil, which plays a key role in automobile power, is the most used and most consumed oil product in automobile lubricants. In recent years, as the working conditions of engine lubricating oil have become more and more harsh, the specifications and varieties of engine lubricating oil have increased, and the quality grade, performance and price have also ...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at the problems of poor thermal stability, easy sedimentation and clogging of oil passages in existing friction modifiers, and general friction reduction effect, and provides a kind of friction modifier with good thermal stability, not easy to sedimentation and clogging of oil passages, good friction reduction effect, and can be used with various friction modifiers. A friction modifier containing nano-mesoporous carbon, which is compatible with lubricating oil, has the characteristics of high temperature resistance, high speed and high load, and avoids carbon deposition.
