Problems solved by technology

Although this method can produce metal and resin composites with higher strength, it needs to prepare different chemical etching solutions for different metals. Since the chemicals used are strong acids and alkalis, the waste etching solutions are difficult to handle, which is not conducive to environmental protection.

Embodiment Construction

[0022] see figure 1 , The metal-resin composite body 10 of the preferred embodiment of the present invention includes a metal part 20 and a resin part 30 combined with the metal part.

[0023] The surface 201 of the metal piece 20 is formed with several micropores 22, and the opening diameter d of the micropores 22 is 1 smaller than the hole bottom diameter d 2 , where the opening diameter d 1 It is about 5-50 microns, and the depth is about 25-300 microns. The material of the metal parts can be aluminum alloy, magnesium alloy, stainless steel, copper and copper alloy.

[0024] The resin part 30 is partly intruded into the micropore 22 to combine with the metal part 20 by means of injection or thermal fusion. The resin member 30 is composed of a crystalline thermoplastic resin, which may be a mixture of polyphenylene sulfide (PPS) and glass fiber, polyamide (PA), polyethylene terephthalate (PET), or polyethylene terephthalate (PET). Butylene Terephthalate (PBT). If it is...

Abstract

The invention provides a manufacturing method for a compound of metal and resin. The method comprises the following steps of: providing a metal component; degreasing, deoiling and cleaning the metal component; etching the metal component by using a focused ion beam to form a nano hole dot matrix on the surface of the metal component; embedding the metal component into a forming mould and heating the metal component to 100-350 DEG C; and injecting molten crystalline thermoplastic resin into the mould and cooling, wherein the resin invades nano holes on the surface of the metal component to be combined with the metal component.

Description

technical field [0001] The invention relates to a method for manufacturing a composite body of metal and resin. Background technique [0002] In practical applications, it is often necessary to connect metal and resin to form a composite. One of the existing metal and resin connection methods is to use adhesives for bonding, but high-strength metal and resin composites cannot be produced by bonding with adhesives. [0003] Another connection method is to form holes on the surface of the metal parts by chemical etching, then put the metal parts into the mold, and inject resin to combine with the metal parts. Although this method can produce metal and resin composites with higher strength, it needs to prepare different chemical etching solutions for different metals. Since the chemicals used are strong acids and alkalis, the waste etching solutions are difficult to handle, which is not conducive to environmental protection. Contents of the invention [0004] In view of thi...
