Embodiment 1

[0034] Energy-saving diesel engine oil raw materials (parts by weight): 0.9 parts of monoalkenyl succinimide, 0.5 parts of calcium alkylbenzenesulfonate, 0.6 parts of antiwear agent, 0.5 parts of 4,4'-dioctyl diphenylamine, 2- 0.5 parts of tert-butyl-4,6-dimethylphenol, 4 parts of ethylene-propylene copolymer, 0.003 parts of simethicone, and 94 parts of base oil.

[0035] The base oil is obtained by uniformly stirring and mixing pentaerythritol tetramyristate, di-n-octyl adipate and pentaerythritol tetralaurate in a mass ratio of 1:1:1.

[0036] The anti-wear agent is composed of 50wt% N, N-di(2-ethylhexyl) molybdenum dithiocarbamate and 50wt% N, N-bis(tridecyl) molybdenum dithiocarbamate, and stir and mix uniformly get.

[0037] The preparation method of energy-saving diesel engine oil: add one-half of the base oil weight (that is, one-half of the total base oil weight) into the blending kettle, raise the temperature to 85°C, add ethylene-propylene copolymer, 4,4' -Dioctyld...

Embodiment 2

[0039] It is basically the same as Example 1, except that the base oil is uniformly obtained by stirring and mixing di-n-octyl adipate and pentaerythritol tetralaurate at a mass ratio of 1:1. The energy-saving diesel engine oil prepared in Example 2 was obtained.

Embodiment 3

[0041] It is basically the same as Example 1, except that the base oil is uniformly obtained by stirring and mixing pentaerythritol tetramyristate and pentaerythritol tetralaurate at a mass ratio of 1:1. The energy-saving diesel engine oil prepared in Example 3 was obtained.

Abstract

The invention discloses energy-saving diesel engine oil and a preparation method thereof.The energy-saving diesel engine oil is prepared from, by weight, 0.8-1.0 part of monoene succinimide, 0.4-0.6 part of alkyl benzene sulfonic acid, 0.3-0.8 part of antiwear agent, 0.4-0.6 part of 4,4'-dioctyl diphenylamine, 0.4-0.6 part of 2-tert-butyl-4,6-dimethylphenol, 3-8 parts of ethylene-propylene copolymer, 0.002-0.005 part of dimethicone and 90-100 parts of base oil.The energy-saving diesel engine oil is easy to prepare, the wear-resistant and antiwear effect of the diesel engine oil can be effectively improved, fuel consumption is reduced, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, and relates to an energy-saving diesel engine oil and a preparation method thereof. Background technique [0002] Diesel engine oil is an important branch of automotive lubricants, and diesel engines are compression-ignition internal combustion engines. The diesel engine uses compressed air to increase the air temperature beyond the self-ignition point of diesel, and then injects diesel, and the diesel oil mist mixes with air and ignites by itself. Compared with gasoline engines, diesel engines have high thermal efficiency and good fuel economy, and can use cheap heavy oil. The fuel consumption rate is low, followed by a large power and speed range, good environmental protection, and the carbon dioxide emission is about 30-35% lower than that of a gasoline engine. Therefore, it has a wide range of applications, so the demand for diesel engine oil is increasing day by day. [0003] Engi...
