Claim 4:
5. A preparation method for a lubricant for a copper alloy die-casting die, used for preparing the lubricant for the copper alloy die-casting die according to claim 1, specifically comprising the following steps:
S1, quantitatively weighing the components of the inorganic nano-powder, and adding into a high-speed mixer for stirring evenly at a rotational speed of 2100-3000 r/min for a stirring time of 15-60 min;
S2, quantitatively weighing and mixing the components of the organic substrate material; and quantitatively weighing and mixing the components of the organic resin material;
S3, taking the inorganic nano-powder, the organic substrate material, and the organic resin material according to a ratio, first adding the organic substrate material into a grinder, then putting the inorganic nano-powder and the organic resin material in sequence at a uniform speed for mixing to make a mixture, and adding yttrium-stabilized zirconia balls into the grinder during the mixing to grind the mixture into a finished lubricant by ball milling;
wherein the mass ratio of the mixture to the yttrium-stabilized zirconia balls is 1:6.
