Problems solved by technology

[0003] Graphite lubricating oil is a kind of lubricating oil with high efficiency, energy saving and friction reduction. The graphite particles in the graphite lubricating oil in the prior art are easy to precipitate and delaminate in the lubricating oil. The temperature of the production workshop is -5°C, and the relative temperature difference is about 75°C. Due to the large temperature difference, the produced graphite lubricating oil and the high molecular polymer molecular chain in the lubricating oil after cooling shrink rapidly, causing the graphite to precipitate in the lubricating oil and Layered, poor usage and poor quality

Abstract

The invention relates to an energy-saving and anti-friction graphite lubricating oil and methods for making the same. The energy-saving and anti-friction graphite lubricating oil includes 1-3 parts by weight of graphite lubricating oil additive, and 97-99 parts by weight of national standard lubricating oil; the graphite lubricating oil additive includes 10-20 parts by weight of graphite powder, 30-35 parts by weight of dispersant, and 45-60 parts by weight of base oil. Graphite lubricating oil of the present invention is added in automobile engine and transmission case, and in automobile, fuel oil is saved 7-12% in the car that takes gasoline as fuel, and fuel gas is saved 15-20% in the car that takes gas as fuel, and diesel fuel is used as fuel. Save 3-5% of fuel in large and medium-sized vehicles, save 5-8% of gas in large and medium-sized vehicles fueled by gas, reduce the wear and tear of parts by more than double, extend the oil change period of lubricating oil by more than 30%, and reduce carbon monoxide in engine exhaust , carbon dioxide and carbohydrates and other harmful gases more than 30% of the emissions.

Description

technical field [0001] The present invention relates to the application field of lubricating oil for automobiles, ships and industrial transmission systems, in particular to a graphite lubricating oil used in lubricating oils for automobiles and ships engines, variable speed transmission systems of automobiles, ships and other industrial variable speed transmission systems and a preparation method thereof . Background technique [0002] In today's world, friction and wear are the main reasons for material damage and mechanical equipment scrapping. Lubrication technology is an effective means to reduce friction, reduce wear, and prolong the service life of machinery. Reducing friction and wear, improving lubrication effect, and increasing the useful work of equipment Output, reduce energy consumption, an important means of environmental protection. The important method of lubrication technology is to use lubricants. Lubricants are divided into liquid lubricants, solid lubric...
