【発明の詳細な説明】 （産業上の利用分野） 本発明は金属光沢を有する成形品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 producing a molded article with metallic luster.
（従来の技術）
金属光沢を有する成形品は、自動車のホイールカバー等
の如く、美麗な光沢を有し、しかも、軽いので、最近注
目されている商品である。(Prior Art) Molded products with metallic luster, such as automobile wheel covers, have a beautiful luster and are lightweight, so they have been attracting attention recently.
又、軒樋等は、従来、トタンとかブリキ等で作成されて
いたが、錆易いし、施工性に欠けるため、最近、熱可塑
性樹脂製の軒樋が使用されている。Furthermore, eaves gutters and the like have conventionally been made of corrugated iron or tin, but these are prone to rust and lack workability, so eave gutters made of thermoplastic resin have recently been used.
この軒樋は、従来、銅製品が高級品として、重宝されて
いるため、熱可塑性樹脂製の軒樋を、銅製品と同じよう
な光沢を持たせることが要望されている。Conventionally, copper products have been valued as high-class products for eaves gutters, and therefore, there is a demand for eaves gutters made of thermoplastic resin to have the same luster as copper products.
従来、この金属光沢を有する軒樋としては、ＡＢＳ樹脂
（アクリル−ブタジェン−スチレン共重合樹脂）で製造
した軒樋の表面にメツキを施したものが市販されている
。このメツキの製造工程を簡単に記すと、
脱脂−一水洗一一エッチングーーキャタリストー−アク
セレーターーー化学銅メツキー−活性化−一電気メッキ
ーー黒染め一一研磨一一塗装となる。このように、鍍金
を施した軒樋等は、複雑な１１工程を経て、製造されて
いた。Conventionally, as eaves gutters having this metallic luster, those manufactured by plating the surface of eaves gutters made of ABS resin (acrylic-butadiene-styrene copolymer resin) have been commercially available. The manufacturing process for this plating is briefly described as: Degreasing - 1 water washing 11 etching - catalytic converter - accelerator - chemical copper plating - activation - 1 electric plating - black dyeing 11 polishing 11 painting. In this way, plated eaves gutters and the like were manufactured through 11 complicated processes.
又、実公昭５７−７６９８号公報には、軒樋等の表面に
合成樹脂と金属粉末との混合物の層を設ける考案が記載
されている。Furthermore, Japanese Utility Model Publication No. 57-7698 describes a method of providing a layer of a mixture of synthetic resin and metal powder on the surface of eaves gutters and the like.

しかし、上記金属メツキを施した金属光沢を有する成形
品は、金属メツキが剥がれ易いため、上記のように、１
１工程もの複雑な工程を経て、製造される。そのため、
極めて煩瑣であり、高価になるという問題がある。(Problems to be Solved by the Invention) However, since the metal plating of the metal-plated molded product with metallic luster easily peels off, as described above,
It is manufactured through one complicated process. Therefore,
The problem is that it is extremely cumbersome and expensive.
又、実公昭５７−７６９８号公報に記載されている考案
では、合成樹脂と金属粉末との接着性が悪いため、金属
粉末と合成樹脂との境界でミクロクラックが入り、金属
粉末が錆びるという問題があり、又、塗布した合成樹脂
と金属粉末とからなる皮膜が剥離し易いという問題もあ
るから、実用化が困難であった。In addition, in the device described in Japanese Utility Model Publication No. 57-7698, the adhesion between the synthetic resin and the metal powder is poor, which causes microcracks to form at the boundary between the metal powder and the synthetic resin, causing the metal powder to rust. Moreover, there is also the problem that the coat made of the applied synthetic resin and metal powder easily peels off, making it difficult to put it into practical use.
