Problems solved by technology

[0006] Figure 6a The frame body 11 shown is a frame body made of a high-strength resin such as glass fiber reinforced polyamide resin (especially nylon MXD6), which has the advantage that the main body portion 11a and the convex portion 11b can be molded integrally by injection molding. , but it has the following disadvantages: In order to satisfy the strength necessary as a frame with resin, even high-strength resin requires a thickness of at least about 1mm, and there is a limit to thinning
In addition, the electromagnetic shielding performance can be realized by the metal, and the insulation can be realized by the resin part. However, the process of drilling the main body part 12a is required, and there are great restrictions in terms of design.
In addition, since the resin protrusion 12b is formed by physically engaging with the hole formed in the metal main body 12a, there is a disadvantage that the engaging portion is poor in airtightness and waterproof.

Embodiment 1~4

[0194] [Examples 1-4, Comparative Examples 1-3]

[0195] A base layer with a thickness of 1 μm was formed after coating a bisphenol A type epoxy resin on one side of a stainless steel plate (SUS3041 / 2H thickness 0.3 mm).

[0196] Next, follow image 3 In the method shown, a nylon 6 film (manufactured by Mitsubishi Plastics Co., Ltd., melting point: 220° C.) was laminated on the base layer forming surface of the stainless steel plate to obtain a resin / metal composite laminate.

[0197]During lamination, the heating temperature in the heating furnace 24 is set to 350°C, and the reheating temperature, cooling method, and reheating time of the reheating furnace 28 are set as shown in Table 1, thereby forming The crystallinity of the resin layer changes. In addition, the thickness of the formed resin layer (resin layer a) was all 25 micrometers.

[0198] It should be noted that for Examples 3 and 4, samples were produced under the same conditions as in Example 1, and only the me...

reference example 1

[0212] A nylon 66 resin ("CM3001-N" manufactured by Toray, melting point: 265° C.) was melted between two heating rolls to obtain a nylon 66 film having a thickness of 25 μm.

[0213] Using the nylon 66 film instead of the nylon 6 film, a resin layer was formed on the surface of the stainless steel plate in the same procedure as in Example 1 to obtain a resin / metal composite laminate.

[0214] Using this resin / metal composite laminate, a sample for a tensile test was produced in the same manner as in Example 1, and the tensile test was performed in the same manner. Table 2 shows the results.

reference example 2

[0216] The stainless steel plate used in Example 1 was heated to 100°C, and a commercially available nitrile rubber thermocompression adhesive tape (manufactured by Tesa tape, softening point 100°C) was welded to form a resin layer with a thickness of 38 μm, thereby obtaining a resin / Metal composite laminates.

[0217] Using this resin / metal composite laminate, a sample for a tensile test was produced in the same manner as in Example 1, and the tensile test was performed in the same manner. Table 2 shows the results.

[0218] It should be noted that whether or not the resin (resin of the resin layer of the resin / metal composite laminated material) in each example adheres to the injection mold during injection molding (with (○) or without (×)) is also included. Recorded in Table 2.

[0219]

[0220] From the above results, it can be seen that the resin / metal composite laminated material of the present invention having a polyamide-based resin layer having a crystallization ...

Abstract

Disclosed is a resin / metal composite laminate material in which a resin layer is laminated on the surface of a metal sheet, and in which convex sections composed of a synthetic resin can be integrally formed on the resin layer with high bonding strength by injection moulding. The resin / metal composite laminate material has a metal plate, and a resin layer (a) laminated on at least one side of the metal plate, said resin layer (a) having a polyamide resin as the main component. The crystallisation index (I) of the resin layer (a) is 0.40-0.80. (Hm1, Hc1, and Hm2 are the first crystal melting heat, the first crystallisation heat, and the second crystal melting heat as measured by DSC.)

Description

technical field [0001] The present invention relates to a resin / metal composite laminated material and a manufacturing method thereof, particularly to a resin / metal composite laminated material and a manufacturing method thereof, wherein the resin / metal composite laminated material is laminated on at least one side of a metal plate A resin / metal composite laminate having a resin layer a mainly composed of a polyamide resin, or a mixed resin composed of a polycarbonate resin and a polyester resin further laminated on the resin layer a The resin / metal composite laminated material of the resin layer b, the resin / metal composite laminated material is used as a base material for manufacturing a resin / metal composite injection molded body, and the resin / metal composite injection molded body is produced by in-mold Injection molding such as molding or insert molding integrates the protrusions made of synthetic resin on the resin layer a or resin layer b of the resin / metal composite la...
