Problems solved by technology

Patent application document CN104962360A provides a synthetic open gear oil composition, which is blended with three different synthetic ester base oils and compatible with appropriate additives. It has good thermo-oxidative stability, high and low temperature performance and extreme It has good pressure and anti-wear properties, and the viscosity can be adjusted in a wide range, basically meeting the working conditions of various open gear devices. However, because of the complex structure and cumbersome preparation of various synthetic ester oils contained in them, there is currently a lack of corresponding commercial oils in the market. products, so it is impossible to carry out industrial scale-up production

preparation example Construction

[0051] The present invention also provides a method for preparing the open gear oil composition according to the present invention, which includes: mixing the components of the open gear oil composition.

[0052] Specifically, according to the method of the present invention, comprise the following steps:

[0053] Add ester synthetic oil into the reactor, keep the temperature at 75-90°C, then add oil-based antiwear agent, stir until uniform and transparent, stop heating and lower the temperature to 40-60°C, then add extreme pressure antiwear agent , an antioxidant, and a metal passivator are added into a reactor, and stirred until uniform and transparent to obtain an open gear oil composition.

Embodiment 1

[0057] With 94.4 parts by weight of ester synthetic oil (manufacturer: Italmatch Chemicals, brand: Ketjenlube2700, this ester synthetic oil is formed by copolymerization of fourteen alpha olefin, sixteen alpha olefin, and the reaction product of maleic anhydride and ethanol, Its average weight-average molecular weight is 7000Da, CAS number: 173521-40-9) into the reaction kettle, keep the temperature of the kettle at 80°C; add 1 part by weight of dodecyl hydroxystearic acid, stir until uniform and transparent, stop heating and use Cooling water reduces the still temperature to 50°C; then 2 parts by weight of isobutylene sulfide (manufacturer: Boda Chemical Co., Ltd., trade mark: T321, the same below), 1.5 parts by weight of tricresyl phosphate (manufacturer: Bo Da Chemical Co., Ltd., brand: T306, the same below), 1 weight part of octylbutyl diphenylamine, 0.1 weight part of benzotriazole derivatives (manufacturer: Jinzhou Kangtai Lubricating Oil Additive Co., Ltd., brand: T551, ...

Embodiment 2

[0059] The open gear oil composition II was prepared according to the same method as in Example 1, except that 1.5 parts by weight of tricresyl phosphate in Example 1 was replaced by 1.5 parts by weight of isobutylene sulfur.

Abstract

The invention provides an open gear oil composition and a preparation method thereof. The open gear oil composition is prepared from 85.5-99.56%, preferably 90.9-98.37%, more preferably 92-96% of ester synthetic oil, 0.1-8%, preferably 1-6% of anti-wear reagent at extreme pressure, 0.03-3.0%, preferably 0.1-1.5% of oil-based antiabrasive agent, 0.01-0.5%, preferably 0.03-0.1% of metal deactivator and 0.3-3.0%, preferably 0.5-1.5% of antioxygen according to the total weight of the open gear oil composition being 100%. The open gear oil composition has good antiabrasive and abrasion-resistant performance, extremely high bearing capacity and high anti-rust and water-resistant performance, further has excellent low-temperature fluidity and high-temperature adhesion and excellent shear stability, and has the wide application range, and no oil is shed when the open gear oil composition is used for a long time.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to an open gear oil composition and a preparation method thereof. Background technique [0002] Open gear oil is mainly used to lubricate the running gears of open and semi-open gearboxes and low-speed heavy-duty gear devices. It is used in the working machinery of cement, metallurgy, mining and other industries, especially in some extra-large rotating equipment. There are a wide range of applications. Since the open (or semi-open) transmission is exposed, it is easy to be affected by dust or other external factors during work and cause wear and oil deterioration. Therefore, open gear oil requires good adhesion, adhesion Temperature characteristics, extreme pressure and anti-wear properties, etc., to ensure that the gear surface has sufficient oil film protection during the low-speed operation of the open gear. [0003] Open gear oil products are generally divided into a...
