Problems solved by technology

Traditional lubricating oil is difficult to lubricate under harsh conditions such as long time, high temperature, and high load, especially the in-situ dynamic self-repair of the surface of the friction pair. Therefore, it is urgent to develop new high-efficiency anti-friction self-repair and life-extending materials and technologies

preparation example Construction

[0040] The invention provides a preparation method of internal combustion engine oil for crawler tanks, comprising the following steps:

[0041] 1) Preheat the base oil first, then add pour point depressant, viscosity index improver, alkyl zinc dithiophosphate, alkyl diphenylamine, metal detergent, ashless dispersant and mix to obtain a mixed oil;

[0042] 2) The finished oil is obtained after mixing the nano-scale multi-effect friction agent with the mixed oil.

[0043]In the present invention, the base oil preheating temperature is 55-65°C, preferably 57-62°C, more preferably 60°C.

[0044] In the present invention, in step 1), the mixing speed of the mixed oil is 400-600r / min, and the mixing time is 30-45min; preferably, the mixing speed is 450-550r / min, and the mixing time is 35-42min; More preferably, the mixing speed is 500r / min, and the mixing time is 40min.

[0045] In the present invention, in step 2), after mixing the nano-scale multi-effect friction agent and the ...

Embodiment 1

[0049] According to the proportion by weight, put 43 parts of polyalphaolefin Durasyn 166, 29 parts of Durasyn 180I and 13 parts of diester A1021 synthetic base oil into the reactor, start stirring, and heat to 65°C; put in 0.4 parts of T801, 5.5 parts of SVM5, 2.3 parts of alkyl zinc dithiophosphate, 0.3 part of alkyl diphenylamine, 1.2 parts of high alkali value calcium salicylate T115B, 3.0 parts of T154, stirred and mixed evenly at a rotating speed of 500r / min; Add 2.3 parts of nano-boron ceramic friction modifier, keep the original temperature at 600r / min and continue stirring for 40 minutes; pump it into a storage tank and let it stand for 1 hour to obtain the finished product 1. The physical and chemical properties of finished product 1 are shown in Table 2 below.

Embodiment 2

[0051] According to the proportion by weight, put 46 parts of polyalphaolefin Durasyn 166, 30 parts of Durasyn 180I and 12 parts of diester A1022 synthetic base oil into the reactor, start stirring, and heat to 65°C; put in 0.3 parts of T801, 5.5 parts of SVM5, 1.8 parts of zinc alkyl dithiophosphate, 0.2 part of alkyl diphenylamine, 0.9 part of high alkali value sulfurized calcium alkylphenate T115B, 1.7 parts of T154, stirred and mixed evenly at a rotating speed of 500r / min; Add 1.6 parts of nano-calcium hexadecyl borate, keep the original temperature at 600r / min and continue to stir for 40 minutes; pump it into a storage tank and let it stand for 1 hour to obtain the finished product 2. The physical and chemical properties of the finished product 2 are shown in Table 2 below.

Abstract

The invention provides internal combustion engine oil for a crawler-type tank and a preparation method of the internal combustion engine oil, and belongs to the technical field of vehicle engine lubricating oil. The internal combustion engine oil disclosed by the invention is prepared from the following raw materials in parts by weight: 80.0 to 92.0 parts of base oil, 0.8 to 1.2 parts of a metal detergent, 2.3 to 5.5 parts of an ashless dispersant, 0.7 to 2.1 parts of zinc alkyl dithiophosphate, 0.1 to 0.54 part of a nanoscale multi-effect abrasive, 0.05 to 0.3 part of alkyl diphenylamine, 2.3 to 5.8 parts of a viscosity index improver and 0.3 to 0.8 part of a pour point depressant. The internal combustion engine oil obtained by the invention is a novel lubricating material prepared on the basis of a nano material, and is an internal combustion engine oil which is outstanding in friction resistance, good in fuel economy, long in oil change period, ultralow in tail gas emission and capable of effectively reducing friction loss of an engine.

Description

technical field [0001] The invention relates to the technical field of engine lubricating oil for vehicles, in particular to an internal combustion engine oil for crawler tanks and a preparation method thereof. Background technique [0002] At this stage, tank engines are mainly developing in the direction of high power, and it is necessary to lay the foundation for the development of high-power engines with the help of high-temperature lubrication technology. For tank engines, during the actual operation of the system, components such as pistons, cylinder liners, and valves will be affected by high temperature and friction, which will inevitably cause damage to the performance of components. In order to promote the efficient operation of the engine, the gap between the cylinder liner and the piston ring should be reduced as much as possible to reduce the impact of frictional resistance on the operating efficiency of the engine. In this case, it is required to have better l...
