Embodiment approach
[0163] It should be understood that the embodiments disclosed herein are illustrative in all respects and not restrictive. The scope of the present invention is not limited to the constitution of the above-described embodiments, but is defined by the claims. The scope of the present invention is intended to include equivalents of the claims and all modifications within the scope of the claims. Such as figure 2 and image 3 The examples shown in are representative of embodiments of the invention that can be practiced by making changes as described below.
[0164] figure 2 is a schematic cross-sectional view showing a metal-resin composite according to another embodiment of the present invention. exist figure 2 in, with figure 1 The same components in the metal-resin composite body 1 shown in , are denoted by the same reference numerals and will not be described again.
[0165] figure 2 The metal-resin composite 1A shown in is formed as a laminated body including: a ...
Embodiment 1
[0195] First, cobalt treatment for forming a rust-proof layer on a copper foil (base) having a thickness of 20 μm was performed.
[0196] Next, the copper foil was dipped for 15 seconds in a composition containing a coupling agent prepared by dissolving 1% by mass of 3-aminopropyltriethoxysilane in ethanol for 15 seconds. And prepared. The coupling agent-containing composition was air-dried and then heated in a constant temperature room at 110° C. for five minutes, thereby fixing the coupling agent to the copper foil.
[0197] Next, the damping material, copper foil, fluororesin sheet as a synthetic resin part, copper foil, and damping material are sequentially laminated, followed by hot pressing to form a laminated body as a metal-resin composite.
[0198] Carbon felt with a thickness of 5.0 mm was used as a shock absorbing material.
[0199] As the fluororesin sheet, an FEP film (“NEOFLON FEPNE-2” (manufactured by Daikin Industries, Ltd.)) having a thickness of 30 μm and a...
Embodiment 2 to 6
[0201] (Examples 2 to 6, and Comparative Examples 1 to 15)
[0202] A laminate (metal-resin composite) was prepared in the same manner as in Example 1, except for the following conditions: whether cobalt treatment was performed as shown in Table 1, and the type of silane coupling agent (for Types of silane coupling agents, see Table II).
[0203]
[0204] (Evaluation of joining force)
[0205] The bonding force was evaluated by measuring the peeling force of the copper foil to the fluororesin sheet in the laminate as the peeling strength. According to JISK6854-2:1999 "Adhesives-Determination of peel strength of bonded assemblies, Part 2: 180 degree peel", the peel strength was measured using an "Autograph AG-IS" tensile tester (manufactured by Shimadzu Corporation) as the bonding strength between the copper foil and the fluororesin sheet.
[0206] Table I shows the results of measurement of bonding force of the laminates of Examples 1 to 6 and Comparative Examples 1 to 15....
