Problems solved by technology

[0003] Since the surface of the above-mentioned aluminum alloy has no holes or the holes are too shallow, it is impossible to tightly bond the thermoplastic resin to the metal
Therefore, the thermoplastic resin and metal materials combined by this process often start to peel off after being combined, and cannot be used for a long time

Embodiment Construction

[0016] see figure 1 , figure 1 It is a flow chart of steps of an embodiment of the method for embedding thermoplastic substances into metal materials according to the present invention. exist figure 1 Among them, the method for embedding a thermoplastic substance into a metal material comprises the following steps:

[0017] First, in step S11, a single acidic or mixed acidic solution, an aqueous hydroxide solution, and high-temperature water at 50°C to 120°C are provided, wherein the metal material can be one of aluminum stampings or aluminum materials. The thermoplastic material can be a thermoplastic resin compound, and the thermoplastic resin compound is one of a combination of polyphenylene sulfide components and a combination of polybutylene terephthalate components.

[0018] Next, in step S12 , the metal material is corroded by cleaning the metal material with a single acidic or mixed acidic solution in the form of a high-pressure water curtain, so that a plurality of...

Abstract

The invention discloses a method for embedding a thermoplastic material into a metal material, which comprises the following steps: providing single-acid or mixed-acid solution, water solution of hydroxide and high temperature water with a temperature between 50 and 120 DEG C; utilizing the single-acid or mixed-acid solution to corrode the metal material to produce a plurality of holes on the surface of the metal material; washing the metal material repeatedly with the water solution of hydroxide and continuing to corrode the interiors of the plurality of holes by providing current to the metal material; and then washing the metal material with the high temperature water to produce an oxide film on the metal material, molding the thermoplastic material on the metal material by injection, and combining the thermoplastic material and the metal material into a whole by injecting the thermoplastic material deeply into the plurality of holes.

Description

technical field [0001] The invention relates to a method for embedding thermoplastic substances in metal materials, in particular to a method for repeatedly using aqueous hydroxide solution to clean metal materials and using electric current to corrode metal materials so that thermoplastic substances are embedded in metal materials. Background technique [0002] It is a well-known fact in the industry that the material of ordinary aluminum alloy is relatively soft and not wear-resistant. Therefore, based on the aforementioned characteristics, in order to make the aluminum alloy practically usable, special processing is required during manufacture, and then an oxide film is formed after baking, and finally resin is injected on the surface of the aluminum alloy. [0003] Since the above-mentioned aluminum alloy has no holes or the holes are too shallow, it is impossible to tightly bond the thermoplastic resin to the metal material. Therefore, the thermoplastic resin and metal...
