PLASTIC-METAL COMPOSITE MATERIAL AND MANUFACTURING METHOD THEREOF

摘要

Disclosed are a plastic-metal composite material and a manufacturing method thereof. The method including: S1. injection molding: subjecting a mixture of a metal powder and a binder to injection molding to form a metal structural member of a preset shape; S2. degreasing and sintering: subjecting the metal structural member to degreasing and sintering to remove the binder, to form 0.5-2 μm micron-sized micropores on a surface of the metal structural member; S3. nanocrystallization: on the basis of the micron-sized micropores, forming 20-40 nm nano-sized micropores by etching with a chemical etching reagent; and S4. injection molding: placing the metal structural member filled with a chemical reagent in an injection mold for injection molding to be integrated with a plastic. The composite material is a product manufactured according to the method. The application solves the problem that the metal structural member is difficult to be molded.

1. A manufacturing method of a plastic-metal composite material, wherein the composite material comprises a plastic and a metal, the method comprising:
S1. metal powder injection molding: subjecting a mixture of a metal powder and a binder to injection molding on an injection molding machine to form a metal structural member of a preset shape; S2. metal structural member degreasing and sintering: subjecting the metal structural member to degreasing and sintering to remove the binder, so as to form 0.5-2 μm micron-sized micropores on a surface of the metal structural member; S3. nanocrystallization of the micron-sized micropores: on the basis of the micron-sized micropores, forming 20-40 nm nano-sized micropores by etching with a chemical etching reagent; and S4. injection molding with a mold: placing the metal structural member filled with a chemical reagent in an injection mold for injection molding to be integrated with the plastic.
