  • Coffee lubricant having nanoparticles
    Patent number: 10920168
    Abstract: A coffee lubricant having nanoparticles is provided. It consists of 36 to 40 wt % of glycerin, 1 to 7 wt % of gum arabic, 0.3 to 1.3 wt % of nanoparticles, and remaining part of coffee biofuel. In which, the nanoparticles are CuO. The coffee biofuel is extracted from coffee dregs and has a viscosity of 60 to 70 cSt at a temperature of 40 degrees Celsius. It can reduce the friction coefficient and operating temperature. In addition, it can replace the mineral oil.
