Embodiment Construction

[0017] An energy-saving and environment-friendly gasoline engine lubricating oil, including base oil and additives, the base oil is a fully synthetic polyalphaolefin base oil, and the additives consist of a viscosity index improver, a composite detergent, a composite dispersant, a composite antioxidant and anticorrosion agent, Metal deactivator, antirust agent and antifoaming agent, the mass percentages of each component are: base oil 75%~87%; viscosity index improver 3%~6%; composite detergent 5%~9% ; Composite dispersant 3%~6%; Composite antioxidant and anticorrosion agent 1.5%~3%; Metal deactivator 0.06%~0.1%; Antirust agent 0.05%~0.3%; Antifoam agent 0.02%~0.05%, The sum of the mass percentages of each component is 100%. The viscosity index improver is a low molecular weight polyisobutylene with a molecular weight of less than 1000. The composite detergent is composed of low-alkaline petroleum calcium sulfonate with a mass fraction of 25%~40% and high-alkali synthetic cal...

Abstract

The invention relates to an energy-saving environment-friendly gasoline engine lubricating oil which comprises base oil and additives. The base oil is completely-synthetic poly-alpha-olefin base oil. The additives are composed of the following components in percentage by mass: 75-87% of base oil, 3-6% of viscosity index improver, 5-9% of composite detergent, 3-6% of composite dispersing agent, 1.5-3% of composite antioxidation and anticorrosion additive, 0.06-0.1% of metal passivator, 0.05-0.3% of rust inhibitor and 0.02-0.05% of antifoaming agent. The lubricating oil is composed of the completely-synthetic poly-alpha-olefin base oil, composite antioxidation and anticorrosion additive, composite metal detergent, composite ashless dispersant, metal passivator, rust inhibitor, antifoaming agent and viscosity index improver. The lubricating oil implements energy saving and long oil change period, reduces the discharge of waste oil, waste gas and particles, has higher biodegradability than the traditional lubricating oil, prolongs the fuel economy and service life of the engine, and inhibits the oil sludge and carbon deposit in the engine from generation.

Description

technical field [0001] The invention relates to the technical field of lubricating oil production, in particular to an energy-saving and environment-friendly gasoline engine lubricating oil. Background technique [0002] Lubricating oil is a liquid or liquid used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. [0003] semi-solid. Lubricating oil mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil. It is an important part of lubricating oil to give some new properties. [0004] Additives are the essence of modern advanced lubricants. Proper selection and reasonable addition can improve its physical and chemical p...
