Abstract
A kind of additive for wear resistance of lubricating oil is made up of oil soluble chloro-boron compound 20～80% (weight) and alkaline sulfonate 80～20% (weight).This additive is added to the anti-wear and wear-resistant performance and the supporting capacity that can improve oil product in the lubricating oil.
Description
The present invention has narrated a kind of oil soluble chloro-boron compound type additive for wear resistance of lubricating oil.
As everyone knows, when mechanical part is worked, need apply lubricant in the centre of two contact components under normal and high loading to prevent or to reduce their wearing and tearing and reduce friction.And the use of wear preventive additive can improve the over-all properties of lubricating oil greatly.Boron-containing compound is used as the oxidation-resistance that lubricant additive can improve oil product, United States Patent (USP) (USP) 4410438,4492642,2618437,4541942 and 4701274 have reported a series of borate-type lubricating oil additive, except that carbon containing, hydrogen, also have atoms such as nitrogen, phosphorus, sulphur in the molecular chain alkyl of boric acid ester, this type lubricating oil additive generally only has oxidation-resistance and antifriction function, and wear-resistant especially anti-extreme pressure can be relatively poor.
The object of the present invention is to provide a kind of oil soluble chloro-boron compound type additive for wear resistance of lubricating oil and preparation method thereof, it not only has anti-oxidant, antifriction performance, also has good wear-resistant, anti-extreme pressure energy.
The present invention includes oil soluble chloro-boron compound and alkaline sulfonate.The chloro-boron compound is represented with logical formula I:
N=2～4 wherein, m=2～12.
Alkaline sulfonate is represented with logical formula II:
Wherein R is C

Concrete prescription of the present invention is (weight percentage): the chloro-boride 20～80% of logical formula I, the alkaline sulfonate 80～20% of logical formula II.
As one of active element of lubricating oil antifriction, wear preventive additive, it is easily had an effect generation adsorption film or metal chloride film and has good wear-resistant and anti-extreme pressure energy with the metallic surface with chlorine in the present invention.The alkaline sulfoacid metal-salt has good detergent-dispersant performance, also has corrosion resistance preferably simultaneously, thus itself and contain the compound use of chlorine additive and can more effectively improve the wear-resistant of oil product and anti-extreme pressure energy.

The used alkaline sulfonate of the present invention is alkaline alkyl calcium sulphonate or alkaline alkyl barium sulfonate, and their molecular weight is between 300～800.The ratio (weight percent) of chloro-boron compound involved in the present invention and alkaline sulfonate is between 1: 4 to 4: 1, their weight percentages in oil product are between 1%～10%, best 2%～6% the time when content, can obtain comparatively good antifriction antiwear effect and advantages of high bearing capacity this moment.
In order to understand the present invention better, institute's synthetic chloro-boride and alkaline sulfoacid calcium just to be added under 50 ℃ and 100 ℃ by certain ratio, viscosity is respectively 10.28mm
2/ S, and 3.36mm
2In the whiteruss of/S (white oil), under rotating speed 1480r/min and room temperature, investigated the wear-resistant and anti-extreme pressure energy (pressing GB-3142-82) of oil product with four-ball tester (Shell-Seta Four-ball EP Lubricant Tester).Testing used steel ball is the secondary standard steel ball (GCr15 bearing steel, HRc 59～61) that Lanzhou Berings Factory produces.Test-results is listed in table 1 and the table 2.Result from table 1 as can be seen, chloro-boron
