Energy-saving and synergistic nano graphite lubricant additive and preparation method thereof

Abstract

The invention provides an energy-saving and synergistic nano graphite lubricant additive and a preparation method thereof. The preparation method is characterized by comprising the following steps of: ball-milling graphite powder, deironing, separating and drying, and processing to obtain nano graphite powder; and mixing the nano graphite powder, gear oil, a dispersion stabilizer, basic oil and a solid lubricant to obtain the finished energy-saving and synergistic nano graphite lubricant additive. By the preparation method, the engine can save fuel oil by over 7 percent, reduce the lubricant oil consumption by 50 percent, prolong the oil change period by one time, reduce abrasion of machine parts and prolong the engine overhaul mileage by 50 percent; moreover, the abrasion is reduced, the abrasion rate of an engine cylinder is reduced by 25 to 36 percent, the engine air tightness is increased, the discharge of harmful gases in the tail gas is reduced, and dual benefit of saving the energy and protecting the environment can be gained.

Description

technical field [0001] The invention relates to the technical field of engine lubricating oil additives, in particular to a nano-graphite lubricating, energy-saving and synergistic additive and a preparation method thereof. Background technique [0002] Energy is one of the pillars of modern society, energy is a main indicator of industrial production level, and fuel oil is the main component of energy. As we all know, since the oil crisis, all countries in the world have attached great importance to the development of energy-saving technology. Our country's scientific and technological personnel have also carried out a lot of active research and development of lubricating oil additives, and have made gratifying progress. They have been piloted and promoted in some areas and achieved preliminary results. , but there are disadvantages such as high price, low fuel-saving rate, fuel-saving but not money-saving, single performance, inconsistent lubricating performance, short ser...

As we all know, since the oil crisis, all countries in the world have attached great importance to the development of energy-saving technology. Our country's scientific and technological personnel have also carried out a lot of active research and development of lubricating oil additives, and have made gratifying progress. They have been piloted and promoted in some areas and achieved preliminary results. , but there are disadvantages such as high price, low fuel-saving rate, fuel-saving but not money-saving, single performance, inconsistent lubricating performance, and short service life after adding to lubricating oil, which restricts large-scale promotion and application.
