Abstract

The invention discloses energy-saving and environment-friendly lubricating oil capable of self-repairing wear for an internal combustion engine and a preparation method of the energy-saving and environment-friendly lubricating oil, and belongs to the field of lubricating materials. The energy-saving and environment-friendly lubricating oil is prepared from the following components in percentage by weight: 87 to 90 percent of base oil and 10 to 13 percent of additive, wherein the additive is prepared from the following components in percentage by weight: 1.2 to 2.5 percent of a calcium-containing clearing agent, 1.3 to 2 percent of a dispersing agent, 0.5 to 1.4 percent of an anti-wear agent, 1.5 to 2.5 percent of an antioxidant, 0.5 to 0.8 percent of a corrosion inhibitor, 1.5 to 2 percent of a viscosity index improver and 1.1 to 3.5 percent of a friction improver; the friction improver is polytetrafluoroethylen high-molecular compound ultramicro nano-powder and the particle size of the powder is 2 to 12 nm. According to the energy-saving and environment-friendly lubricating oil disclosed by the invention, the problem that existing lubricating oil for the internal combustion engine cannot repair friction and wear of internal parts in the engine is solved; in addition, the design tolerance gap can be automatically compensated and non-disassembly in-situ repair can be carried out, thereby improving the sealing property of a cylinder, a piston and other parts; in addition, a compression ratio and an air-fuel ratio of the engine are improved, fuel oil is combusted more sufficiently, the discharge of exhaust pollutants is reduced and the frictional resistance is reduced.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to an energy-saving and environment-friendly lubricating oil for an internal combustion engine capable of self-repairing wear and a preparation method thereof. Background technique [0002] The waste of resources caused by friction and wear in the world has exceeded hundreds of billions of dollars every year. Nearly half of the world's energy is consumed by friction and wear, and wear is one of the three main reasons for the scrapping of materials and equipment. [0003] At the same time, the primary issue of today's automobile industry is energy conservation and environmental protection. Motor vehicle exhaust emissions account for more than 50% of urban air pollution, and automobile oil consumption accounts for more than 1 / 3 of the country's oil consumption. Therefore, it is growing at a double-digit rate. The developing Chinese auto industry is facing double bottlenecks of energy and environme...
