Uniformly mixing the chinlon 6 dry slices, the nano-particle germanium powder and the nano-particle meinoside; wherein, the weight percentage of the chinlon 6 dry slice is 92%, the weight percentage of the nano-particle germanium powder is 4%, and the weight percentage of the nano-particle meicarnosine is 4%. After the materials are mixed, the mixture is put into a screw extruder for melting.

Specifically, the screw extruder is divided into 3 sections, which are respectively: add material feeding section, melting section, measurement section, these three sections are corresponding to constitute 3 functional areas to the material, be respectively: a solid conveying area, a material plasticizing area and a melt conveying area.

When the materials are melted, controlling the temperature of a charging barrel of a solid conveying area of the screw extruder to rise from 100 ℃ to 1400 ℃ in 30 minutes; controlling the temperature of a charging barrel in a material plasticizing area to rise from 170 ℃ to 1900 ℃ within 30 minutes, and simultaneously controlling the vacuum degree of the charging barrel to be 0.08 MPa; the barrel temperature in the melt conveying zone was controlled to rise from 160 ℃ to 1800 ℃ in 30 minutes while the screw speed was controlled to 20 r/min.
