Problems solved by technology

[0002] Under harsh working conditions, engine oil and transmission oil will gradually age due to oxidation and other reasons, manifested as thickening, blackening, carbon deposits, sludge, etc. Unsmooth, accelerated wear of parts, early failure time or increased failure rate
The engine oil and gearbox oil need to be replaced regularly, and the engine and gearbox are not easy to disassemble. Therefore, every time the engine oil and gearbox oil are replaced, some residual oil, oxides, and metal chips will remain in the body. Oil work brings a lot of inconvenience

Embodiment 1

[0019] Embodiment 1: (in terms of 100 kilograms, the same below)

[0020]

[0021]

[0022] The composite additive package contains 0.68% sulfur, 0.21% nitrogen and 3.74% calcium.

[0023] The preparation method of synthetic cleaning oil for this engine and gearbox adopts the following steps:

[0024] (1) Pump the oil-soluble polyalkylene glycol and synthetic ester base oil of the above weight into the blender with a gear pump, heat and stir, and mix evenly at a constant temperature of 50°C to obtain a mixed oil A;

[0025] (2) Add the compound additive package of the above weight to the mixed oil A prepared in step (1), and continue mechanical stirring for 1 hour at a constant temperature of 50°C to prepare mixed oil B;

[0026] (3) Filter the mixed oil B prepared in step (2), and filter it through a filter with a filter bag device under a pressure of 0.1 MPa to obtain a clear and transparent synthetic cleaning oil for engines and gearboxes.

Embodiment 2

[0028]

[0029] The composite additive package contains 0.05% sulfur, 0.16% nitrogen and 2.85% calcium.

[0030] The preparation method of synthetic cleaning oil for this engine and gearbox adopts the following steps:

[0031] (1) Pump the oil-soluble polyalkylene glycol and polyol ester base oil of the above weight into the blender with a gear pump, heat and stir, and mix evenly at a constant temperature of 55°C to obtain a mixed oil A;

[0032] (2) Add the compound additive package of the above weight to the mixed oil A prepared in step (1), and continue to mechanically stir for 1.5 hours at a constant temperature of 55°C to prepare mixed oil B;

[0033] (3) Filter the mixed oil B prepared in step (2), and filter it through a filter with a filter bag device under a pressure of 0.15 MPa to obtain a clear and transparent synthetic cleaning oil for engines and gearboxes.

Embodiment 3

[0035]

[0036] The composite additive package contains 2.4% sulfur, 0.73% nitrogen and 7.26% calcium.

[0037] The preparation method of synthetic cleaning oil for this engine and gearbox adopts the following steps:

[0038] (1) Pump the oil-soluble polyalkylene glycol and synthetic ester base oil of the above weight into the blender with a gear pump, heat and stir, and mix evenly at a constant temperature of 60°C to obtain a mixed oil A;

[0039] (2) Add the compound additive package of the above weight to the mixed oil A prepared in step (1), and continue to mechanically stir for 2 hours at a constant temperature of 60°C to prepare mixed oil B;

[0040] (3) Filter the mixed oil B prepared in step (2), and filter it through a filter with a filter bag device under a pressure of 0.2 MPa to obtain a clear and transparent synthetic cleaning oil for engines and gearboxes.

Abstract

The invention relates to the field of lubricating oil, and particularly discloses a synthetic cleaning oil for an engine and a gearbox, and a preparation method of the synthetic cleaning oil. The synthetic cleaning oil for the engine and the gearbox comprises the following components by weight: 3.01-13% of composite additive package, 70-90% of oil-soluble polyalkylene glycol, and the balance of synthetic ester base oil. The synthetic cleaning oil for the engine and the gearbox has the beneficial effects that the synthetic cleaning oil for the engine and the gearbox is safe and convenient to use, is good in mobility, extremely low in volatility, and excellent in viscosity-temperature characteristic and cleaning performance, has excellent compatibility with an engine oil and a gearbox oil, and can be directly added into the old oil and cleaned after the engine and the gearbox are opened, a low quantity of synthetic oil left in the engine and the gearbox after cleaning can also well protect the engine and the gearbox, the settlings like oil sludge and carbon deposition in the engine and the gearbox are effectively cleaned, metal pieces in the engine and the gearbox are protected against corrosion and wear, the working efficiency of the engine is improved, and gear shift is smoothly and stably conducted.

Description

(1) Technical field [0001] The invention relates to the field of lubricating oil, in particular to a synthetic cleaning oil for engines and gearboxes and a preparation method thereof. (2) Background technology [0002] Under harsh working conditions, engine oil and transmission oil will gradually age due to oxidation and other reasons, manifested as thickening, blackening, carbon deposits, sludge, etc. Unsmooth, accelerated wear of parts, early failure time or increased failure rate. The engine oil and gearbox oil need to be replaced regularly, and the engine and gearbox are not easy to disassemble. Therefore, every time the engine oil and gearbox oil are replaced, some residual oil, oxides, and metal chips will remain in the body. Oil work has brought a lot of inconvenience. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides an engine and gearbox with reasonable components, safe and convenient...
