The present invention relates to a novel alkyl thiadiazole thiester compound and an antiwear agent comprising the same.

최근 산업의 발전에 따라 정밀 기기나 각종 산업용 부품 등은 보다 가혹한 환경조건하에서 작동되도록 요구되고 있으며 이를 만족시키기 위해 내마모능이 우수한 첨가제를 사용하고 있다.Recently, according to the development of the industry, precision instruments and various industrial parts are required to operate under harsher environmental conditions, and to satisfy these requirements, additives having excellent wear resistance are used.

이러한 내마모 첨가제는 윤활유에 포함되어 금속 표면에 필름을 형성하여 금속과 금속의 접촉에 의하여 생기는 마모를 방지함으로 내하중 능력을 발휘하는 첨가제이다. 금속과 금속의 접촉에 의해 생기는 마모를 줄임으로써 기계의 효율을 향상시키고 연료의 소비를 절감시키고 에너지를 줄일 수 있는 장점이 있으나, 사용 중에 누유될 시 토양오염, 수질오염 등을 유발하는 단점이 있어 사용량을 줄여야 하는 단점이 있다.Such anti-wear additives are additives that are included in the lubricating oil to form a film on the metal surface to prevent abrasion caused by the contact between the metal and the metal to exert a load carrying capacity. It has the advantage of improving the efficiency of the machine, reducing fuel consumption and reducing energy by reducing wear caused by metal-to-metal contact, but it has the disadvantage of causing soil pollution, water pollution, etc. when it is leaked during use. There is a downside to reducing usage.

이와 같이 내마모성 향상을 위해 사용되는 첨가제는 금속 표면에서 필름을 형성하여 물리적 또는 화학적인 기능을 하기 때문에, 첨가제에 함유되어 있는 화학적 구조와 원소에 따라 내마모제로의 기능을 발휘하여 금속과의 마찰로 인하여 발생하는 에너지를 현저하게 절감하여 효과적이고 상용성이 우수한 내마모성을 나타낸다.As the additive used to improve the wear resistance has a physical or chemical function by forming a film on the metal surface, the additive acts as an anti-wear agent according to the chemical structure and the elements contained in the additive, thereby causing friction with the metal. Significantly reduces the energy generated, showing effective wear resistance with good compatibility.
