Lubricating oil and application thereof

Abstract

The invention provides lubricating oil and application thereof. The lubricating oil is prepared from the following components by weight percent: 70-90% of base oil, 6-15% of a diesel engine oil compound agent, 3-15% of a viscosity index improver, 0.1-0.5% of a pour point depressant and 0.1-1% of friction improver, wherein the base oil is prepared by mixing hydrogenated base oil II and brighteningbase oil. The lubricating oil is prepared from the base oil and the additives; a good synergistic effect is achieved due to the combination of the compound type base oil and the improvers, so that theanti-friction, anti-wear and energy-saving effects are enabled to be more obvious. Under the actual working conditions, molybdenum dialkyl dithiophosphate or molybdenum dialkyl dithiocarbamate release active element sulfur or phosphorus in a friction process under high temperature and high pressure and chemically react with the metals on the friction surface, so that complex compounds such as phosphides and sulfides are generated and deposited on the friction surface; therefore, the lubricating oil has the effects of wear resistance, noise reduction and energy conservation on engines, and theengines, cylinders and other equipment are better protected by means of the lubricating oil.

Description

technical field [0001] The invention relates to the field of engine oil, in particular to a lubricating oil and its application. Background technique [0002] Friction produces force, which has different meanings in different environments. For the engine system, the friction from the mechanical parts will cause the wear of the mechanical parts and the effort of the movement. When we fill the equipment with lubricating oil (commonly known as "oil"), the lubricating oil is forced to circulate or splash through the oil pump. Among the friction parts of the engine, an oil film is formed on the surface of the friction parts, so that the dry friction between metals on the friction surface becomes a liquid friction between lubricating oils. Now consumers have higher and higher requirements for car comfort. Wear reduction, low noise, energy saving, and long oil change intervals have become hot spots, which have also aroused the exploration of lubricating oil manufacturers. Meets i...
