Abstract

The invention discloses environment-friendly and energy-saving gasoline engine oil and a preparation method thereof. The environment-friendly and energy-saving gasoline engine oil is prepared from the following raw materials in parts by weight: 70-85 parts of environment-friendly base oil, 0.8-3.0 parts of a complex antioxidant, 3.7-6.7 parts of a metal detergent, 5.8-7.8 parts of an ashless dispersant, 0.7-1.5 parts of a nanoscale friction modifier, 4.0-10.0 parts of a viscosity index improver and 0.2-1.0 part of a pour-point depressant. The preparation method comprises the following steps: feeding the environment-friendly base oil to an adjustable dehydrator; sequentially feeding the pour-point depressant, the viscosity index improver, the complex antioxidant, the metal detergent and the ashless dispersant when stirring at 58-65 DEG C, and stirring evenly; and feeding the nanoscale friction modifier, keeping at 58-65 DEG C, further stirring for 1.5 hours, and standing for 0.5 hour, so as to obtain the environment-friendly and energy-saving gasoline engine oil which meets the API SN/GF-5 requirements and is long in service life.

Description

technical field [0001] The invention relates to an environment-friendly and energy-saving gasoline engine oil and a preparation method thereof, belonging to the research field of automobile engine lubricating oil. technical background [0002] Most modern lubricants are composed of more than 80% base oil, plus various additives. Base oil is undoubtedly the decisive factor for lubricants to affect the environment or ecology. Base oils that can be used as environmentally friendly lubricants mainly include polyethers and synthetic esters. Their physical and chemical properties have their own characteristics. At present, the environmentally friendly base oils widely used are mainly synthetic vinegar and vegetable oil. With the improvement of human awareness of environmental protection, people pay close attention to the environmental pollution caused by lubricating oil. Some countries have legislated to prohibit the use of lubricating oil that does not meet the requirements of b...
