Abstract

The invention relates to a preparation method for energy-saving and environment-friendly diesel engine oil. The diesel engine oil is prepared from the raw materials: 87-92 parts of synthetic base oil, 4.4-5.2 parts of dispersant, 2.4-3.1 parts of anti-wear agent, 1.5-2.3 parts of composite antioxidant, 1.8-2.2 parts of ashless friction modifier, 1.3-1.6 parts of viscosity index improver, 0.6-0.8 part of metal cleaning agent, 0.5-0.7 part of pour point depressant, 0.3-0.5 part of ZDDP and 0.2-0.3 part of antifoamer. The preparation method comprises the following steps of adding the synthetic base oil into a blending kettle, sequentially adding the dispersant, the anti-wear agent, the composite antioxidant, the viscosity index improver, the metal cleaning agent, the pour point depressant and the ZDDP into the blending kettle with stirring at the temperature of 60 DEG C to 65 DEG C, carrying out uniform stirring, then, sequentially adding the ashless friction modifier and the antifoamer into the blending kettle, continuing to carry out stirring for 1.5 to 2 hours while maintaining the temperature to 60 DEG C to 65 DEG C, and then, carry out standing for 0.5 to 1 hour, thereby obtaining the energy-saving and environment-friendly diesel engine oil.

Description

technical field [0001] The invention relates to the technical field of energy-saving and environment-friendly lubricating oil used in the automobile industry, in particular to a method for preparing energy-saving and environment-friendly diesel engine oil. Background technique [0002] Today, with the rising oil price, the energy-saving requirements of automobiles are also increasing. Although there are many new energy sources: hydrogen power, fuel cells or hybrid power, etc., new energy vehicles are also gradually becoming practical, but from the perspective of real economy and practicality At this stage, using new diesel engines as vehicle power is undoubtedly one of the most feasible solutions. The market share of diesel locomotives in the EU passenger car market reached a new high in 2005. As the world's second largest automobile consumer market, the economy and strong power of diesel engines are in line with the development trend of the European market. [0003] In th...
