Embodiment 1

[0080] (1) Making metal substrate

[0081](1-1) Use the CorelDRAW drawing software to design the arrangement map file of the hole, and input it into the control unit of the laser, so that the laser can be placed on the aluminum alloy substrate (purchased from Titanium Technology Co., Ltd.) as the metal substrate according to the arrangement map file. Co., Ltd., the brand name is A6061) on the surface forms holes that exist in pairs and intersect at the bottom, and at the same time make the holes in pairs as a unit and arrange them into a two-dimensional lattice.

[0082] Among them, according to Figure 4 to Figure 13 The method is to form a pair of holes with intersecting bottoms on the surface of the aluminum alloy substrate, and the specific process flow is as follows.

[0083] The first step: if Figure 4 and 5 As shown, the laser beam 4 is obliquely incident with respect to the surface of the metal substrate 3 (in a clockwise direction, the incident angle of the laser ...

Embodiment 2

[0096] (1) Making metal substrate

[0097] The metal matrix was fabricated by the same method as in Example 1, except that, in the two-dimensional lattice, there was no misalignment between two adjacent rows (that is, there was no staggered arrangement between two adjacent rows).

[0098] (2) Making metal-resin composites

[0099] The metal-resin composite was fabricated by the same method as in step (2) of Example 1, except that the metal matrix was the metal matrix produced in step (1) of Example 2.

[0100] The mechanical property data of the prepared metal-resin composites are listed in Table 1.

Embodiment 3

[0102] (1) Making metal substrate

[0103] The metal substrate was fabricated by the same method as in step (1) of Example 1, except that step (1-2) was not performed.

[0104] (2) Making metal-resin composites

[0105] The metal base was fabricated by the same method as in step (1) of Example 1, except that the metal base was the metal base prepared in step (1) of Example 3.

[0106] The mechanical property data of the prepared metal-resin composites are listed in Table 1.

Abstract

The invention discloses a metal-resin composite body and a preparation method thereof. The composite body includes a metal base body and a resin layer attached to at least part of the surface of the metal base body. The surface of the metal base body attached to the resin layer is distributed with Holes, the holes appear in pairs, and the wall of at least one of the two holes that are a pair of holes is inclined, the angle of the inclination makes the two holes that are a pair of holes intersect, and the resin layer Part of the resin extends down and fills the hole. In the composite body, the resin filled in the holes in the resin layer forms a closed structure in the metal matrix, which can well resist the rotational moment, and can further improve the ability to resist tensile stress. The preparation method of the composite body is simple, for example, by irradiating the surface of the metal base material with laser light, and making the laser beam obliquely incident, holes with inclined hole walls can be formed in the metal base material.

Description

technical field [0001] The invention relates to a metal-resin composite body and a preparation method thereof. Background technique [0002] In the field of mobile electronic device manufacturing, metal and resin integrated molding technology is required. [0003] The commonly used method of combining metal and resin is gluing technology. This method combines metal and shaped resin with a chemical adhesive to create a composite body. In addition, micropores are formed on the metal surface by etching, anodic oxidation, etc., and then the resin is injected on the metal surface, so that the metal and the resin are combined to form a composite. [0004] The metal-resin composite obtained by the existing method is subjected to tensile stress (such as figure 1 Force F in 1 ), it shows better structural stability; however, when subjected to rotational moments (such as figure 1 Force F in 2 ), the interface between the metal and the resin is easily broken and the composite str...
