Problems solved by technology

However, in this way, the surface of the aluminum alloy is a single layer of fine holes, which is easy to peel off under the different expansion coefficients of the aluminum alloy and thermoplastic resin, so it needs to be sandblasted first, and then a coating film is formed.

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings, but the implementation scope of the present invention is not limited.

[0037] Please refer to Figure 1a , is a schematic diagram of pretreatment according to a preferred embodiment of the present invention. First of all, 1xxx to 7xxx series aluminum alloys are sliced ​​10 times before containing NaOH, KOH, NaOH 2 CO 3 The concentration of the solution is about 1-10% molar equivalent, soaking at 20° C. to 60° C. for 10 seconds to 3 minutes to remove grease, dust and dense oxides on the surface of the aluminum alloy.

[0038] When the dense oxide on the surface of the aluminum alloy 10 is removed, it is different from soaking in a solution containing amine or amine derivatives in the prior art to form a chemical substance attached to the surface of the aluminum alloy. The method of the present invention is to make the surface of the aluminum alloy 10 larger Staggered...

Abstract

The invention provides a method for manufacturing a combination of an aluminum alloy and a thermoplastic resin, which at least comprises the following steps: providing an aluminum alloy sheet; performing pretreatment of removing a surface compact oxide layer on the aluminum alloy sheet; performing corrosion treatment at least comprising a plurality of two-layer micron-level holes on the surface of the aluminum alloy sheet; putting the aluminum alloy sheet in a die; and pouring the molten thermoplastic resin into the die to form the combination of the aluminum alloy and the thermoplastic resin. Because the thermoplastic resin and the aluminum alloy are not easy to strip, the combination has the advantages of both a metal shell and a thermoplastic resin structure in electronic machines and household electric appliances and has high production efficiency and the property of mass production, and the shape and the structure of the combination can be designed freely.

Description

technical field [0001] The invention provides a method for manufacturing an aluminum alloy and thermoplastic resin combination. More specifically, the invention relates to a composition of aluminum alloy shapes and thermoplastic resin produced by various mechanical processing methods to form a structure with high bonding strength , It can be used in the production method of aluminum alloy and resin combination used in various electronic products for portable use, home appliances, other structural parts or exterior decoration parts. Background technique [0002] Technology for firmly integrating metals and resins is required in a wide range of fields such as consumer electronics and home electrical products, and many adhesives (adhesives) have been developed, and many very good adhesives have been proposed. . Adhesives that volatilize at room temperature or by heating are used to integrally bond metal and synthetic resin, and this method is now a commonly used technique. ...
