Abstract
The compounded high-effective wear-resisting antifriction agent is made up by using organic molybdenum wear-resisting antifriction agent, zinc dialkyl dithiophosphate and alkyl-sulphide benzo thiazole as raw material through the process of mixing under the proper condition. Said invention can be added to lubricating oil of internal combustion engine, the mechanical wear rate of said internal combustion engine can be reduced by 60-90%, and 0.5%-2.0% of said invention is added to lubricator, its lubricating property can be obviously improved. Said invention utilizes the synergistic effect of said raw materials in wear-resisting, antioxidation, anti-corrosionand anti-rust to obtain the compounded high-effective wear-resisting antifriction agent.
Description
The present invention relates to organic-molybdenum anti-friction agent, zinc dialkyl dithiophosphate and alkylthio benzothiazole is raw material, mixes a kind of compound high-effect wear-resistant friction reducer that obtains under proper condition.
Organomolybdenum wear-resistant friction reducer (or claiming extreme pressure anti-wear additives, friction improver) is the high-effect wear-resistant antifriction additive of lubricant.Add the extreme pressure and antiwear behavior that a small amount of organic-molybdenum anti-friction agent can increase substantially lubricant in lubricant, reduce frictional coefficient, secondary wearing and tearing reduce friction.But there is the active sulphur composition mostly in the agent of synthetic organic-molybdenum anti-friction under the existing processing condition, and in use can further discharge the active sulphur objectionable impurities, and metal is played corrosive nature, and is especially obvious to the corrosive nature of copper and copper alloy.
Zinc dialkyl dithiophosphate is important lubricant additive, has good antioxygen antiseptic property, have certain extreme pressure and antiwear behavior and organic-molybdenum anti-friction agent simultaneously and use at antiwear and antifriction when shared and have synergistic effect, can further improve the extreme pressure and antiwear behavior of lubricant.But zinc dialkyl dithiophosphate uses mainly as antioxidant preservative traditionally.
The alkylthio benzothiazole is a kind of oil soluble metal passivator.Be used for lubricant, can effectively stop the corrosion of metal, particularly copper and copper alloy.Alkylthio benzothiazole and zinc dialkyl dithiophosphate and organic-molybdenum anti-friction agent have good consistency.Alkylthio benzothiazole and zinc dialkyl dithiophosphate are common to lubricant, and be anticorrosion at antioxygen, stop and to have the obvious synergistic effect aspect the corrosion of metal.
The objective of the invention is, utilize organic-molybdenum anti-friction agent and the zinc dialkyl dithiophosphate synergistic effect aspect antiwear and antifriction, zinc dialkyl dithiophosphate and alkylthio benzothiazole be anticorrosion at antioxygen, stop the synergistic effect aspect the corrosion of metal, obtains a kind of compound high-effect wear-resistant friction reducer with high value of practical.
Compound high-effect wear-resistant friction reducer of the present invention be a kind of by organic-molybdenum anti-friction agent, zinc dialkyl dithiophosphate and alkylthio benzothiazole more than 60-80 degree centigrade, mix the mixture that obtains under the condition of the better flowing property of the equal tool of each component, wherein the ratio of organic-molybdenum anti-friction agent in system is comparatively suitable with 50-60%.
Compound high-effect wear-resistant friction reducer of the present invention, its major ingredient organic-molybdenum anti-friction agent are by molybdate compound and sulphur phosphoric acid [(RO)

2O).The technological process of using the synthetic organic-molybdenum anti-friction agent of Sodium orthomolybdate is shown in figure one:
In lubricant, add 0.5-2.0% compound high-effect wear-resistant friction reducer of the present invention and can significantly improve lubricity, compound high-effect wear-resistant friction reducer of the present invention is made an addition in the internal combustion (IC) engine lubricating oil, can make mechanical wear rate decline 60-90%.
The ratio of compound high-effect wear-resistant friction reducer of the present invention with 0.5-2.0% made an addition in the lubricant base, carry out copper strip test, the result is one-level.
Distinguishing feature of the present invention is: utilize organic-molybdenum anti-friction agent and the zinc dialkyl dithiophosphate synergistic effect aspect extreme pressure and antiwear behavior, zinc dialkyl dithiophosphate and alkylthio benzothiazole be anticorrosion at antioxygen, stop the synergistic effect aspect the corrosion of metal, give full play to the advantage of each component, obtain a kind of compound high-effect wear-resistant friction reducer with high value of practical.
