Problems solved by technology

[0002] The current lubricating oil mainly includes hydrocarbon lubricating oil and perfluoroether oil. Ordinary hydrocarbon lubricating oil has a high temperature resistance of only 250°C, poor solubilization effect, and unsatisfactory wear resistance; the use time is only about 5000 hours, and after long-term use It is easy to oxidize, resulting in a decrease in lubricating performance, so it cannot meet the needs of the development of industries such as automobiles, ocean transportation, and machinery in recent years
Perfluoropolyether oil has the advantages of high temperature resistance up to 280 ° C, good anti-wear performance, not easy to oxidize, and long service life, but the cost is high, especially it is not compatible with the base oil, and the high temperature stability and compatibility are poor after mixing. Therefore use is limited

Embodiment 1

[0011] Add 400g of 200SN base oil to a 1000ml four-necked flask equipped with a stirrer, condenser, thermometer, dropping funnel, and nitrogen conduit, start stirring, control the temperature at 40-50℃, and slowly add F(CF 2 ) 6 (CH 2 ) 4 4 g of perfluoroalkyl alkane telomer with H structure was stirred for 1 hour and filtered to obtain fluorine-containing lubricating oil. The wear resistance test conditions were carried out on a four-ball machine at 392N, 1200 rpm, temperature 75°C, and 3 hours after evaluation. The comparison data of wear scar diameter was 1.25 for 200SN, 0.52 for ordinary lubricating oil, and 0.10 for fluorine-containing lubricating oil. The lubricating oil contrast is reduced by 80%.

Embodiment 2

[0013] Add 500g of 200SN base oil to a 1000ml four-necked flask equipped with a stirrer, condenser, thermometer, dropping funnel, and nitrogen conduit, start stirring, control the temperature at 70-80℃, and slowly add F(CF 2 ) 6 (CH 2 ) 4 0.50 g of the H structure perfluoroalkyl alkane telomer was stirred for 0.5 hours and then filtered to obtain a fluorine-containing lubricating oil. The wear resistance test conditions were carried out on a four-ball machine at 392N, 1200 rpm, temperature 75°C, and 4 hours after evaluation. The comparison data of wear scar diameter was 1.25 for 200SN, 0.57 for ordinary lubricating oil, and 0.22 for fluorine-containing lubricating oil. Lubricating oil is reduced by 60%.

Embodiment 3

[0015] Add 500g of 200SN base oil into a 1000ml four-necked flask equipped with a stirrer, condenser, thermometer, dropping funnel, and nitrogen conduit, start stirring, control the temperature at 50-60℃, and slowly add F(CF 2 ) 8 CH 2 CH 2 -(C 6 H 5 )-(SO 3 -Ca-SO 3 )(CaCO 3 ) b -(C 6 H 5 )-(C 2 H 4 )-(CF 2 ) 8 20 g of calcium salt of perfluoroalkyl sulfonate with F structure was stirred for 0.5 hours and filtered to obtain fluorine-containing lubricating oil. The wear resistance test conditions were carried out on a four-ball machine at 392N, 1200 rpm, temperature 75°C, and 5 hours after evaluation. The comparison data of wear scar diameter was 1.25 for 200SN, 0.58 for ordinary lubricating oil, 0.148 for fluorine-containing lubricating oil, and reduced mechanical wear by 74 %.

Abstract

The invention discloses a fluorine-containing lubricating oil which composed of 100 parts by weight of base oil and 0.1-5 parts by weight of fluorine group containing additive, wherein the fluorine group containing additive is at least one of perfluoro alkyl alkane telomere, perfluorononanesulfonic acid calcium salt and perfluorononanesulfonic acid zinc salt, and the base oil is 100SN (serial number), 150SN or 200SN. In the invention, the fluorine group containing additive and the base oil are adopted as raw materials and no independent processing on the base oil is required, compared with perfluoropolyether (PFPE), the invention has advantages of simple process, low cost, good compatibility and difficult oxidation and high cost performance, no pollution and good properties of the obtained fluorine-containing lubricating oil, compared with ordinary lubricating oil, the invention has the advantages of energy conservation and long service time which can reach more than 8000 hours, fuel oil can be saved by more than 10% (not mentioned in the embodiment), and mechanical wear can be reduced by more than 60%.

Description

Technical field [0001] The invention relates to a fluorine-containing lubricating oil. Background technique [0002] The current lubricating oils mainly include hydrocarbon lubricating oil and perfluoroether oil. The high temperature resistance of ordinary hydrocarbon lubricating oil is only 250℃, which has poor solubilization effect and unsatisfactory abrasion resistance; the use time is only about 5000 hours, after long time use Easy to oxidize, resulting in lower lubrication performance, so it cannot meet the needs of the development of automobiles, ocean transportation, machinery and other industries in recent years. Perfluoropolyether oil has the advantages of high temperature resistance up to 280°C, good abrasion resistance, not easy to oxidize, and long use time, but it has high cost, especially because it has no compatibility with base oil, poor high temperature stability after mixing, and poor compatibility. Therefore use is restricted. Summary of the invention [0003]...
