［産業上の利用分野］
本発明は、合成樹脂を基材としてその表面に金
属或はセラミツクス等の薄い層を一体に結合して
なる複合材の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a composite material made of a synthetic resin base material and a thin layer of metal or ceramics etc. bonded to the surface thereof.
［従来の技術］
従来、合成樹脂と金属等からなる複合材は多種
存在する。例えば、合成樹脂の表面に接着剤によ

法等がある。[Prior Art] Conventionally, there are many types of composite materials made of synthetic resins, metals, and the like. For example, there is a method in which a metal plate is attached to the surface of a synthetic resin with an adhesive, or a method in which a composite material is manufactured by mixing metal powder during injection molding of a synthetic resin.
［発明が解決しようとする問題点］
従来技術において、接着剤を使用する場合には
永年の使用により金属板が剥離する虞れがある。
また、金属粉末を混入させながら射出成型する方
法では成形物の表面に集中させて、かつ全体に均
一に金属の層を形成することが難しく、特に成形
物の形状が複雑である場合には困難である。[Problems to be Solved by the Invention] In the prior art, when an adhesive is used, there is a risk that the metal plate will peel off after long-term use.
In addition, when injection molding is performed while mixing metal powder, it is difficult to concentrate the metal on the surface of the molded product and form a uniform layer over the entire surface, which is especially difficult when the shape of the molded product is complex. It is.
［問題点を解決するための手段］
そこで本発明は、合成樹脂の発泡体１表面に金
属、セラミツクス等の粉状体２を塗着し、これを
金型３内で加熱しながら押圧成形するようにして

したものである。[Means for Solving the Problems] Therefore, in the present invention, a powder 2 of metal, ceramics, etc. is applied to the surface of a synthetic resin foam 1, and this is press-molded while being heated in a mold 3. In this manner, a composite material 4 made of synthetic resin as a base material is manufactured.

れる。[Operation] When the powder 2 is applied to the surface of the foam 1, the powder 2 enters the recesses 1' on the surface of the foam 1. When the foam 1 is pressed while being heated in this state, the recess 1' is crushed while holding the powder 2 in its mouth, and the powder 2 is wrapped in the recess 1'. Furthermore, the powdered material 2 that is not enclosed within the recess 1' is integrally bonded by the synthetic resin being melted by heating.
［実施例］

ある。 FIG. 1A shows a state in which powder 2 is applied to the surface of a synthetic resin foam 1. As is well known, the foam 1 has recesses 1' and bubbles 1'' formed on its surface and inside, so the powder 2 applied to the surface enters the recesses 1' (see enlarged section a in the figure). ).The powder 2 is selected from metals such as zinc, tin, aluminum, or ceramics depending on the purpose.For example, when the composite material 4 obtained by the present invention is used as an electromagnetic shielding material, Metal powders such as zinc, tin, and aluminum are used, and ceramic powders are also used when used as building materials that similarly require durability.
なお、粉状体２を塗着する手段としては第一に
溶射技術の応用が考えられるが、エアブラシ等で
吹き付けて塗着するようにしてもよい。 The first possible method for applying the powder 2 is to apply a thermal spraying technique, but it may also be applied by spraying with an airbrush or the like.
次に、第１図ロに示したように発泡体１を金型

れる。 Next, as shown in FIG. 1B, the foam 1 is placed on a mold 3, and while the foam 1 is heated, it is press-molded as shown in FIG. Then, first of all, the recess 1' and the bubble 1'' are crushed.At this time, the recess 1'
The powder 2 that had entered the recess 1' is crushed and enveloped therein (see enlarged section b in the figure). Further, the powdered material 2 located outside the recess 1' is combined and integrated with the foamed material 1 in a heated and melted state.
なお本実施例では粉状体２を発泡体１の片面に
のみ塗着したがもちろんこれに限定されるもので
はなく、粉状体２の塗着を発泡体１の両面に行な
い、かつ異なる材質の粉状体２を使用して各材質
の特性を併せ持つた複合材を製造することも可能
である。 In this example, the powder 2 was applied only to one side of the foam 1, but the invention is not limited to this, and the powder 2 was applied to both sides of the foam 1, and different materials were used. It is also possible to use the powder 2 to produce a composite material that has the characteristics of each material.
［発明の効果］
以上のように本発明によれば、合成樹脂の表面
に確実に粉状体を結合することができる。[Effects of the Invention] As described above, according to the present invention, powder can be reliably bonded to the surface of a synthetic resin.
また、予じめ発泡体の表面に粉状体を塗着した
後に任意の形状に成型するため、いかに複雑な形
状であつてもその表面全体に均一な状態で金属等
の層を形成することができるものである。 In addition, since powder is applied to the surface of the foam in advance and then molded into any desired shape, a layer of metal etc. can be formed uniformly over the entire surface, no matter how complex the shape. It is something that can be done.
