More Information
Summary:The present invention relates to a lubricating oil composition. More particularly, the present invention relates to a lubricating oil composition suitable for hydraulic oil having excellent oxidation stability and frictional characteristics even under a high-temperature, high-pressure, and poor environment. To this end, the lubricating oil composition comprises: a base oil, a liquid olefin copolymer, a phosphorothioate compound and phosphonium phosphate. 본 발명은 윤활유 조성물에 관한 것으로서, 좀 더 자세하게는 고온, 고압의 열악한 환경하에도 우수한 산화안정성 및 마찰특성을 가져 유압작동유에 적합한 윤활유 조성물에 관한 것이다. 본 발명은 베이스 오일, 액상 올레핀 공중합체, 포스포로티오에이트(phosphorothioate) 화합물 및 포스포늄 포스페이트를 포함하는 윤활유 조성물을 제공한다.
