Example Embodiment

[0009] Example 1

[0010] The present invention is a high temperature resistant lubricating oil composition, which is made of the following parts by weight of raw materials:

[0011] 3 parts of vinyl chloride, 2.1 parts of nitrobenzoic acid, 18 parts of Turkish oil, 3.5 parts of pentaerythritol tetraacrylate, 1.8 parts of nano-zirconia, and 4 parts of silica.

Example Embodiment

[0012] Example 2

[0013] The present invention is a high temperature resistant lubricating oil composition, which is made of the following parts by weight of raw materials:

[0014] 2.5 parts of vinyl chloride, 1.5 parts of nitrobenzoic acid, 15 parts of Turkish oil, 2.5 parts of pentaerythritol tetraacrylate, 1.5 parts of nano-zirconia and 3 parts of silica.

Example Embodiment

[0015] Example 3

[0016] The present invention is a high temperature resistant lubricating oil composition, which is made of the following parts by weight of raw materials:

[0017] 4.3 parts of vinyl chloride, 2.2 parts of nitrobenzoic acid, 25 parts of Turkish oil, 4.1 parts of pentaerythritol tetraacrylate, 2.2 parts of nano-zirconia, and 6 parts of silica.

[0018] The lubricating oil composition for gears provided by the present invention has excellent viscosity-temperature performance, high viscosity index, and ensures that the oil has suitable viscosity and film thickness when used in a wide temperature range, and has a low freezing point. It still has better fluidity at lower temperature, which is good for pumping or carrying to the lubrication point, ensuring the safety index of oil use, and is beneficial to the transportation, storage and use of oil. Common gear oil will enter a small amount of water. Emulsification occurs, which causes the lubricating oil film to break...

Abstract

The invention discloses a high temperature-resistant lubricating oil composition which is prepared by the following raw materials by weight: 2.5-4.3 parts of vinyl chloride, 1.5-2.2 parts of nitrobenzoic acid, 15-25 parts of Turkey oil, 2.5-4.1 parts of pentaerythritol tetracrylate, 1.5-2.2 parts of nanometer zirconia, and 3-6 parts of silica. The lubricating oil composition for gears provided in the invention has excellent viscosity-temperature property and a high viscosity index; when used in a wide temperature range, the oil product still has proper viscosity and oil film thickness, and a low condensation point; the oil product has good fluidity at low temperature, which facilitates pumping or carrying to lubrication points, guarantees the safety indexes for the application of the oil product, and facilitates the transport, storage and application of the oil product. Common gear oil emulsifies when mixed with a little water, which may cause lubricating oil film breakup and failure, while the synthetic gear oil provided in the invention still has good lubricity when mixed with 20% water.

Description

technical field [0001] The invention relates to a high temperature resistant lubricating oil composition, which belongs to the field of industrial chemical industry. Background technique [0002] Gear oil is an important lubricating oil prepared mainly from mineral base oil or synthetic base oil, adding extreme pressure anti-wear agent and oily agent. It is used in various gear transmission devices to prevent tooth surface wear and abrasion , sintering, etc., to prolong its service life, improve the efficiency of power transmission, and reduce power loss. Gear oil should have good anti-wear, load resistance and suitable viscosity. In addition, it should also have good thermo-oxidative stability, anti-foaming properties, water separation performance and anti-rust performance. Even under high operating temperature and load, the synthetic gear oil can still ensure that the various parts of the transmission system are not worn. In industrial production, cooling water often lea...
