Embodiment 1

[0023] Add 214.5 kg of 500SN base oil to a blending kettle with a stirrer, stir and heat up to 115°C, add 70 kg of phenyl-1-naphthylamine, and wait until the phenyl-1-naphthylamine is completely dissolved, then stir at a constant temperature Add 450 kg of oleic acid-modified potassium monoborate with a particle size of 55 nm, 250 kg of BT154, 0.5 kg of T901, and 15 kg of DL-32. After the addition is complete, stir at a constant temperature of 100°C for 1 hour, cool to below 60°C, filter and package the finished product.

[0024] The performance of the ISO VG320 industrial gear oil made of the anti-micropitting gear oil compound additive 2.5% and ISO VG320 base oil prepared in this example is shown in the serial number 1 in the attached table 1.

Embodiment 2

[0026] In a mixing kettle with a stirrer, add 214.5 kg of 500SN base oil, stir and heat up to 115°C, add 35 kg of phenyl-1-naphthylamine, 35 kg of 2,6-di-tert-butyl p-cresol, wait After phenyl-1-naphthylamine and 2,6-di-tert-butyl-p-cresol are completely dissolved, add 450 kg of oleic acid-modified potassium monoborate with a particle size of 92nm, 250 kg of BT154, and 0.5 kg of MS-5A, 15 kg DL-32. After the addition is complete, stir at a constant temperature of 100°C for 1 hour, cool to below 60°C, filter and package the finished product.

[0027] The performance of the ISO VG320 industrial gear oil prepared with the anti-micropitting gear oil compound additive 2.5% and ISO VG320 base oil in this embodiment is shown in the serial number 2 in the attached table 1.

Embodiment 3

[0029] Add 222.7 kg of 500SN base oil to a blending kettle with a stirrer, stir and heat up to 115°C, add 60 kg of phenyl-1-naphthylamine, and wait until the phenyl-1-naphthylamine is completely dissolved, then stir at a constant temperature Add 470 kg of oleic acid-modified potassium metaborate with a particle size of 92 nm, 230 kg of BT154, 0.3 kg of T901, and 17 kg of DL-32. After the addition is complete, stir at a constant temperature of 100°C for 1 hour, cool to below 60°C, filter and package the finished product.

[0030] The performance of the ISO VG320 industrial gear oil prepared with 2.5% of the anti-micropitting gear oil composite additive prepared in this example and ISO VG320 base oil is shown in the serial number 3 in the attached table 1.

Abstract

The invention relates to an anti-micro pitting gear oil composite additive, which comprises the following components in percentage by weight: 5 to 10 percent of antioxygen, 30 to 50 percent of oleic acid modified nano borate, 20 to 30 percent of dispersant, 1 to 20 percent of emulsion breaker and the balance of base oil. The gear oil composite additive also comprises 0.03 to 0.1 weight percent ofanti-foaming agent. When 1.5 to 5 mass percent of the gear oil composite additive is added into the base oil at a proper viscosity, gear oil for wind power generator can be prepared. The gear oil forwind power generator does not contain thial extreme-pressure wear-resistance additive, has outstanding anti-micro pitting effect, and overcomes the drawbacks such as low anti-micro pitting performance of common gear oil. The gear oil composite additive is applicable to other kinds of industrial gear oil.

Description

technical field [0001] The invention relates to the field of lubricating oil additives, in particular to an anti-micropitting compound additive for gear oil. Background technique [0002] With the continuous development of clean energy, wind power is developing rapidly in the world. However, due to the environmental conditions of the wind power generator, the gears of the wind power generator are often prone to pitting corrosion, which greatly shortens the service life of the gear. Studies have shown that the main cause of pitting corrosion in gear oil is related to the sulfur (especially active sulfur) additives in the gear oil formula used. [0003] In order to solve the micropitting problem of wind power gear oil, a lot of research has been done abroad, and some additive manufacturers have also developed corresponding composite additive products, such as: Hitec307 of Afton Company, etc. [0004] Although there are reports on gear oil composite additives at home, such as...
