Abstract

The invention discloses environment-friendly and energy-saving diesel engine oil and preparation method thereof. The environment-friendly and energy-saving diesel engine oil consists of the following components in parts by weight: 72-85 parts of synthetic base oil, 0.7-2.0 parts of a complex antioxidant, 4.5-6.2 parts of a metal detergent, 5.1-7.3 parts of an ash-free dispersant, 0.5-1.5 parts of a nano-grade friction modifier, 4.0-10.0 parts of a viscosity index improver and 0.2-1.0 part of pour point depressant. The preparation method comprises the following steps: adding the synthetic base oil to a blending kettle; stirring at 58-65 DEG C, sequentially adding the pour point depressant, the viscosity index improver, the complex antioxidant, the metal detergent and the ash-free dispersant, and uniformly stirring; then, adding the nano-grade friction modifier, adding a defoaming agent, keeping temperature at 58-65 DEG C and continuing to stir for 1.5h; and then standing by for 0.5h so as to obtain the environment-friendly and energy-saving diesel engine oil which meets API CJ-4 requirement.

Description

technical field [0001] The invention relates to an environment-friendly and energy-saving diesel engine oil and a preparation method thereof, belonging to the research field of vehicle engine lubricating oil. Background technique [0002] As the international community pays more and more attention to the ecological environment, biodegradable and environmentally friendly lubricants with low ecotoxicity are being studied to replace traditional mineral-based lubricants. [0003] Internal combustion engine oil is an essential consumable for automobiles. With the strengthening of environmental protection awareness and environmental protection legislation, people pay more and more attention to the environmental pollution of internal combustion engine oil and other lubricants. According to statistics, 600,000 tons of lubricants are lost to the environment in the European Community every year; in the United States, since most drivers change their own oil, more than 700 million liter...
