Embodiment 1～3
[0029] Heat the refined mineral oil to 40°C, add the required amount of oily agent, extreme pressure agent, copper corrosion inhibitor and antioxidant in sequence during stirring, stop stirring and heating after stirring for 1 hour, and filter and pour after standing for 2 hours loading. The type and amount of each component in the composition are specifically shown in Table 1. Wherein, the base oil is refined dearomatized solvent oil with a distillation range of 287-395°C and a viscosity of 6.67mm 2 / s (40°C), the flash point (opening) is 164°C.
