Abstract
The present invention relates to chemical field, more particularly to a kind of high-quality lubricating oil.The high-quality lubricating oil, is formulated by following components by weight：320 400 parts of lube base oil, 69 parts of octyl phenol, 35 parts of alkyl calcium salicylate, 23 parts of fluorinated surfactant, 24 parts of cinnamyl alcohol, N, 8 10 parts of N dimethylformamides, 8 12 parts of Gemini quaternary ammonium salts, 69 parts of diisocyanate.The beneficial effects of the invention are as follows：The antifreeze of lubricating oil, viscosity, antirust, wear-resisting property can be improved, the quality of lubricating oil is greatly promoted.
Description
（One）Technical field
The invention belongs to chemical field, more particularly to a kind of high-quality lubricating oil.
（Two）Background technology
Lubricating oil is usually the product for being fractionated oil, also has and is refined from vegetable and animals oils, including " lubricating grease ".Generally it is not easy
The oily lubricant of volatilization.Various types are used in mechanically to reduce friction, protect the fluid lubricant of machinery and workpiece,
The effects that mainly playing lubrication, cooling, antirust, cleaning, sealing and buffering.It, often will be in lubricating oil to improve the quality of lubricating oil
Additive is added in base oil to improve the various performances of lubricating oil, the additive sold in market is typically all above each list
The combination product of one additive, it is different be exactly single additive ingredient is different and compound additive inside several single add
Add the ratio of agent different.But the synergistic effect after additive addition is poor, and while improving a certain performance, meeting
The reduction for causing another performance causes certain performance of lubricating oil to be short of, influences normal use.
（Three）Invention content
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of high performance high-quality lubricating oil.
The present invention is achieved through the following technical solutions：
A kind of high-quality lubricating oil, is formulated by following components by weight：320-400 parts of lube base oil, octyl phenol
6-9 parts, 3-5 parts of alkyl calcium salicylate, 2-3 parts of fluorinated surfactant, 2-4 parts of cinnamyl alcohol, 8-10 parts of n,N-Dimethylformamide,
8-12 parts of Gemini quaternary ammonium salts, 6-9 parts of diisocyanate.
Preferably, a kind of high-quality lubricating oil, is formulated by following components by weight：360 parts of lube base oil,
7.8 parts of octyl phenol, 4 parts of alkyl calcium salicylate, 2.5 parts of fluorinated surfactant, 3 parts of cinnamyl alcohol, 8 parts of n,N-Dimethylformamide,
11 parts of Gemini quaternary ammonium salts, 7 parts of diisocyanate.
The fluorinated surfactant is Sodium perfluorooctanoate or perfluoro octyl sulfonic acid sodium.
The lube base oil is mineral oil base oil.
The beneficial effects of the invention are as follows：Made by the compounding of a variety of auxiliary agents by adding lube oil additive in lubricating oil
With, Additive Properties can be optimized, it is the effect that can reach good enhancing lubricants performance that can use less additive,
The antifreeze of lubricating oil, viscosity, antirust, wear-resisting property can be improved, the quality of lubricating oil, formula provided by the invention are greatly promoted
Manufactured lubricating oil has better antifreeze, antirust, wear-resisting greasy property relative to other combined lubrication oil.
