Abstract

The invention provides an energy-saving complete-synthesis gasoline engine oil and a synthesis method thereof, and is used for solving the problems of high freezing point and great influence by ambient temperature in the existing gasoline engine oil. The gasoline engine oil comprises 80-90 wt% of base oil, 9-19.998 wt% of compound additive and 0.001-0.002 wt% of defoaming agent; and the base oil is prepared by polymerizing 96-98 wt% of alkyl benzene and 1-2 wt% of high-polymer binary ethyl and propyl olefin by using 1-2 wt% of catalyst. The invention also provides a synthesis method of the energy-saving complete-synthesis gasoline engine oil, which comprises the following steps: preparing the base oil, preparing the compound additive and preparing the complete-synthesis gasoline engine oil. The energy-saving complete-synthesis gasoline engine oil provided by the invention has the advantages of low production cost, excellent lubricating property and favorable economic benefit, conforms to the requirements for energy saving and emission reduction, and can implement large-scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to an energy-saving fully synthetic gasoline engine oil and a synthesis method thereof. Background technique [0002] With the development of society and economy, automobiles have become the most common means of transportation. The existing gasoline engine oil is mainly prepared with mineral oil as the base oil. The lubricating oil obtained has high cost and high freezing point. Lubricating oil often freezes during winter use in cold northern regions, which affects the use effect. [0003] In addition, in order to ensure the normal operation of the engine, low friction and wear and a long service life, the engine oil should have good lubrication and anti-friction effects, cooling engine parts, sealing the combustion chamber, and keeping lubricating parts clean, especially It can reduce the generation of sludge and the deposition of paint film, prevent rust and corrosion under the ...
