Embodiment Construction

[0012] The present invention also provides a preparation method for the above-mentioned synthetic diesel engine oil, comprising the following steps: in mass percentage,

[0013] Step 1: Pump 69% of Korean Ssangyong 250N Group III base oil into the blending kettle through a screw pump, turn on the heating and pulse, and control the base oil temperature at 60°C±5°C.

[0014] Step 2: Pump the high-viscosity polyalphaolefin PAO200 into the blending kettle through a screw pump, and control the temperature at 60°C±5°C, and turn on the pulse to fully mix the two base oils.

[0015] Step 3: Slowly add 0.3% of Romanx T1-248 pour point depressant into the blending kettle, and start the pulse, the pulse time is controlled at 20min, so that the pour point depressant can be fully dissolved into the base oil.

[0016] Step 4: Pump 16% Afton Chemical H8788LA into the blending kettle through a screw pump, control the temperature at 60°C±5°C, turn on the pulse, and control the pulse time at 30...

Abstract

The invention discloses synthetic diesel engine oil. The synthetic diesel engine oil comprises, in percentage by mass, 68%-71% of group III base oil, 14%-16% of high-viscosity group IV base oil, 14%-16% of a compound additive and 0.3% of a pour point depressant. In the diesel engine oil, the group III base oil has good oxidation stability, the shear resistance of lubricating oil is guaranteed without any viscosity index improver, the pressure cannot be reduced in the long oil change period, the oil film strength of the lubricating oil is enhanced by use of high-viscosity synthetic base oil, and strong enough oil film protection can be provided in the long-kilometer driving process of an engine.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a novel synthetic diesel engine oil. Background technique [0002] With the rapid progress of science and technology, the rapid development of modern industry and the improvement of global environmental protection and energy-saving awareness, people's requirements for the comprehensive performance of diesel engines are also constantly improving. Diesel engine oil with low comprehensive performance can no longer meet the needs of modern industrialization. While the standards of high-performance diesel engine oil are constantly being upgraded, the test techniques and theoretical methods for evaluating the performance of diesel engine oil are also being followed up accordingly, such as long oil change intervals. The oil change interval of diesel engines is getting longer and longer, which not only effectively saves the cost of oil change, but also reduces pollution. More an...
