preparation example Construction

[0028] The preparation method of the metal-plastic composite of the present invention at least includes providing a metal component having the nano-scale concave-convex structure through chemical treatment on the bonding surface, and using the PEBA material to insert the metal component into the mold Implement the combined process.

[0029] According to an embodiment of the present invention, the selected metal material is preprocessed into a metal member (also called a metal member base material) of a designed shape and structure, and the bonding surface of the metal member is chemically treated to form the nanoscale concave-convex structure , can be realized according to conventional methods and existing reported implementations. For example, chemically etching (corroding) a pre-processed (not limited to machining, casting, forging, etc.) metal component base material in a set area to form a nanoscale concave-convex structure through acid and / or alkali treatment, or Combini...

Embodiment 1

[0042] 1. Pretreatment of metal components

[0043] 1) Preprocessing and treatment of metal substrates

[0044] Commercially available aluminum alloy plate A1100, 1.5mm thick, is processed into several rectangular sheets of 50mmx10mm, ground and polished, placed in a cleaning tank, washed with absolute ethanol, and then immersed in 40g / L sodium hydroxide aqueous solution, approx. Take it out for 2-3 minutes, rinse it with deionized water and dry it in the air to obtain a decontaminated and degreased aluminum alloy flake substrate.

[0045] 2) Surface etching of metal substrates

[0046] The aluminum alloy flake base material that has been decontaminated and degreased above is used as an anode and placed in an anodic oxidation tank containing 20 wt% sulfuric acid, electrolyzed at 20V and 18-20°C for 10min, and the aluminum alloy sheet is taken out and dried;

[0047] Soak the obtained aluminum alloy sheet in about 10wt% sodium carbonate solution (pH=12), soak at 20°C for 5-6m...

Embodiment 2

[0072] The selection and pretreatment of the metal substrate (aluminum alloy) are the same as in Example 1. The elastomer is commercially available Arkema4533. Using multiple injection molding processes, first obtain a composite body combining the metal substrate and the PEBA elastomer according to the method of Example 1. , and then use another polymer material: commercially available PPSTOSOSGX-120 (polyphenylene sulfide glass fiber reinforcement) injection molding again, so that the other side of the metal substrate is compounded with different plastic layers.

[0073] Choose different molds according to the needs, and obtain a composite body in which different bonding surfaces of the metal substrate are combined with plastic layers of different materials, such as figure 2 shown.

[0074] Similar operations such as image 3 As shown, different regions of a certain joint surface of the metal substrate are combined with composites of plastic layers of different materials th...

Abstract

The invention relates to a complex of metal and plastic and a manufacturing method of the complex. The complex is formed by combining a metal member, of which a combining surface has at least a part of area in a nanoscale concave-convex structure after chemical treatment, with a plastic material; the metal member and the plastic material are tightly combined in an inserting structure in the area; the metal member comprises a metal material member or an alloy material member; the plastic material mainly contains polyether block amide, and is a single-layer or layered structure. Corresponding combining and treatment technologies are matched specifically for the characteristics of the selected plastic material, so that a binding force between metal and plastic is excellent, the sealing characteristic to a certain extent is provided, the impact resistance is excellent, and the appearance decorative effect is diversified.

Description

technical field [0001] The invention relates to the integrated manufacturing technology of metal and plastic materials, in particular to a metal and plastic composite body capable of providing waterproof, dustproof and shockproof functions and a manufacturing method thereof. Background technique [0002] With the development and extension of the manufacturing industry, the technology of integrating and compounding metal and plastic materials (polymer materials such as resins and elastomers) is widely used in the manufacturing of automobiles, household electrification products, industrial equipment and other components, and even personal daily products. There is a very large demand in a wide range of industries. The development of manufacturing technology effectively combines the strength and rigidity of metals with the plasticity of plastic materials, providing a wider range of applications. The integrated combination of metal and plastic materials can be realized through f...
