Problems solved by technology

For example, a compound internal combustion engine oil additive is disclosed in CN1523092A, which is used to improve the performance of internal combustion engine oil, but this additive is only suitable for internal combustion engine oil, and cannot be widely used in the field of gear oil
[0004] The existing gear oil additive preparation process is relatively complicated, the cost is high, and the amount added during use is large, and there are still further problems in improving extreme pressure and wear resistance and viscosity-temperature performance, reducing noise, energy saving and environmental protection, and friction reduction and efficiency enhancement. Room for improvement and improvement

Embodiment 1

[0017] Add 12 parts of graphite, 12 parts of sodium metaborate, 8 parts of polyisobutylene succinimide, 50 parts of base oil 150SN, and 8 parts of 500SN into the emulsification kettle and raise the temperature to about 60°C, and disperse and emulsify for 2 hours;

[0018] The obtained product is pumped to the dehydration tank for heating, vacuumed and dehydrated under negative pressure, the heating temperature is controlled at about 66°C, the negative pressure is controlled at 0.08Mpa, and the time is 2 hours;

[0019] The obtained product was transported back to the emulsification tank, and 10 parts of polymethacrylate was added for emulsification and dispersion for 0.5 hours, and then pumped to a grinder for grinding for 2 hours;

[0020] The obtained product was sent to an ultrasonic vibration tank for ultrasonic vibration for 1 hour;

[0021] The obtained product is filtered through a filter to obtain the composite gear oil additive 1, and the filter diameter is controlled...

Embodiment 2

[0024] The following raw material proportions are adopted: 16 parts of graphite (same as Example 1), 9 parts of bis-succinimide, 15 parts of potassium metaborate, 46 parts of base oil 150SN, 6 parts of BS150, polymethacrylate and ethylene-propylene 8 parts of glue copolymer. Except for this, a composite gear oil additive 2 was obtained in the same manner as in Example 1.

Embodiment 3

[0026] The following raw material proportions are used: 20 parts of graphite, 7 parts of bis-succinimide, 2 parts of monosuccinimide, 13 parts of potassium triborate, 50 parts of base oil 500SN, and 8 parts of polymethacrylate. Here, the graphite is amorphous graphite with a purity of 99%, 85% by weight of particles with a particle size of 0.5 microns or less, and the maximum particle size is not more than 5 microns. Except for this, a composite gear oil additive 3 was obtained in the same manner as in Example 1.

Abstract

The invention relates to a compound gear oil additive containing graphite, borate, a dispersant, a stabilizer and base oil, the composition of materials includes, in weight percent, graphite 10 to 20 percent, dispersant 5 to 9 percent, stabilizer 5 to 10 percent, borate 10 to 20 percent, balance base oil, and the sum of all percents of materials is equal to a hundred percent. The compound gear oil additive has the advantage of low cost, and has properties of obviously improved anti-wear performance under extreme pressure, noise reduction, energy saving, environmental protection, anti-attrition and synergism, etc. by only adding a small amount of additive when in use.

Description

technical field [0001] The invention relates to the field of lubricating oil additives, in particular to a composite gear oil additive. Background technique [0002] Lubricating oil is a lubricant applied to mechanical equipment such as automobile engines with two friction surfaces in relative motion. By forming a lubricating film between the two friction surfaces, the surfaces in direct contact are separated and dried. Friction is the internal friction between lubricant molecules to achieve the purpose of reducing friction, reducing wear, and prolonging the service life of mechanical equipment. [0003] In order to further improve or improve the lubricating performance of the lubricating oil, additives are usually added to the lubricating oil. For example, CN1523092A discloses a composite internal combustion engine oil additive for improving the performance of internal combustion engine oil, but this additive is only suitable for internal combustion engine oil and cannot b...
