용해성 윤활유 첨가제로서 molybdenum di-n-butoxydithiophosphate(MoDTP)의 마모 및 마찰감소에 대하여 시험하였다. Molybdenum di-n- butoxydithiophosphate(MoDTP), zinc di-n-buthyldithiophosphate(ZnDTP), 그리고 MoS2의 현탁용액의 경계윤활 특성 효과를 Timken과 Four-Ball 시험을 통하여 비교한 결과, molybdenum di-n-butoxydithiophosphate 용액의 극압 및 내마모 성질이 다른 것 들보다 우수하였다. 또한 MoDTP가 첨가된 윤활유의 동판부식에 대한 산화안정성과 부식방지성 효과가 특히 양호하였다.


Molybdenum di-n-butoxydithiophosphate was investigated as a soluble lubricating oil additive for reducing wear and friction. The boundary lubricating effects of oil solutions of molybdenum di-n-butoxydithiophosphate(MoDTP), zinc di-n-buthyldithiophosphate(ZnDTP), and MoS2 supension were compared through Timken and Four-Ball testes. The results showed that the extreme pressure and antiwear properties of the solution of molybdenum di-n-butoxydithiophosphate were superior to those of other additives. Also, the antioxidation and anticorrosion properties for copper strip in oil with added molybdenum di-n-butoxydithiophosphate were found to be especially excellent.
