Zusammenfassung:	The invention belongs to the technical field of copper alloys and manufacturing thereof, and particularly relates to a copper alloy hot extrusion die material based on a high-entropy alloy and a multi-component water-based lubricating coating and a preparation method of the copper alloy hot extrusion die material. A CoCrNiCuFe high-entropy alloy is adopted as a base material of a hot extrusion copper and copper alloy die, then Ti3SiC2 which has a high melting point, high thermal stability and good oxidation resistance and is self-lubricating at a high temperature is adopted as a reinforcing phase, the strength of the CoCrNiCuFe high-entropy alloy is further improved, the CoCrNiCuFe high-entropy alloy is made to have better lubrication and wear resistance in a high-temperature environment, and on the basis, the strength of the CoCrNiCuFe high-entropy alloy is improved. And a multi-component water-based lubricating coating is introduced to the surface of the copper alloy, so that the lubricating performance of
