High-viscosity repair type engine anti-wear agent capable of reducing exhaust and preparing method of engine anti-wear agent

Abstract

The invention discloses a high-viscosity repair type engine anti-wear agent capable of reducing exhaust and a preparing method of the engine anti-wear agent. The high-viscosity repair type engine anti-wear agent capable of reducing exhaust is prepared from, by mass, 5-10% of organic molybdenum, 5-10% of organic tungsten, 5-10% of nitrogenous boric acid ester, 0-5% of an extreme pressure anti-wear agent, 10-30% of a dispersing agent, 10-20% of high-viscosity polyester, 10-20% of composite ester and the balance base oil. The high-viscosity repair type engine anti-wear agent capable of reducing exhaust has good wear-resisting and friction-reducing performance, good resistance to oxidation, good cleanliness and good sealing performance and can be widely applied to engines of overload heavy vehicles and aged and used vehicles, a very good wear-resisting repair effect can be achieved on the metal surfaces of slightly-worn parts inside engines, and the service life of the engines is prolonged; especially, a good sealing effect can be achieved between one engine piston and a piston ring and between the engine piston and a cylinder sleeve, the problem of engine oil combustion caused by upward engine oil leakage and engine oil oxidation caused by downward gas leakage is solved, and the cylinder pressure is increased so that fuel oil can be sufficiently combusted, exhaust emission is reduced, fuel oil consumption can be reduced, engine noise can be effectively lowered, and the engine power can be improved; the content of sulfur and phosphate is low, and the requirement for environment friendliness is met.

Description

technical field [0001] The invention relates to the technical field of engine lubricating oil, in particular to a high-viscosity repair type engine anti-wear agent for reducing exhaust gas and a preparation method thereof. Background technique [0002] In the past ten years, my country's automobile industry has developed rapidly, and the number of automobiles has increased significantly year by year. The automobile transportation industry has become an important industry in economic development. The engines of these vehicles often experience abnormal wear and tear; many car owners lack awareness of vehicle maintenance, lack of maintenance of the engine, and some even use inferior oil, causing abnormal wear of engine components; most areas of our country have poor road conditions, especially in mountainous areas, In mining areas, vehicles often work under the harsh working conditions of low speed, high speed and high torque, which is very easy to cause abnormal wear and tear; d...

AI Technical Summary

Problems solved by technology

Due to the increasingly stringent emission regulations of modern engines, the higher and higher energy-saving requirements and the application of new materials, the wear resistance of the engine friction pair surface is improved, the gap in the structural design becomes smaller, and the lubricating oil film strength and film-forming ability increase and become lower. Viscosity. At present, most of the engine lubrication system maintenance products on the market are extreme pressure and anti-wear products, and their main function is to seal and boost pressure. They are added to the crankcase to change the viscosity of the engine oil and increase it. At the same time, due to the traditional oil usage habits, domestic The viscosity of lubricating oil used by car owners is generally high, which is not conducive to fuel saving
