Description

本発明は、メッキ強度が高いメッキ樹脂成形体と、エッチング工程が不要となるメッキ樹脂成形体の製造法に関する。   The present invention relates to a plated resin molded body having high plating strength and a method for producing a plated resin molded body that does not require an etching process.

自動車を軽量化する目的から、自動車部品としてABS樹脂やポリアミド樹脂等の樹脂成形体が使用されており、この樹脂成形体に高級感や美感を付与するため、銅、ニッケル等のメッキが施されている。   For the purpose of reducing the weight of automobiles, resin molded bodies such as ABS resin and polyamide resin are used as automobile parts. To give this resin molded body a high-class feeling and aesthetics, copper, nickel, etc. are plated. ing.

従来、ABS樹脂等の成形体にメッキを施す場合、樹脂成形体とメッキ層との密着強度を高めるため、脱脂工程の後に樹脂成形体を粗面化するエッチング工程が必須である。例えば、ABS樹脂成形体やポリプロピレン成形体をメッキする場合、脱脂処理の後に、クロム酸浴(三酸化クロム及び硫酸の混液)を用い、65〜70℃、10〜15分でエッチング処理する必要があり、廃水には有毒な6価のクロム酸イオンが含まれる。このため、6価のクロム酸イオンを3価のイオンに還元した後に中和沈殿させる処理が必須となり、廃水処理時の問題がある。   Conventionally, when plating a molded body such as an ABS resin, an etching process for roughening the resin molded body after the degreasing process is essential in order to increase the adhesion strength between the resin molded body and the plating layer. For example, when plating an ABS resin molded body or a polypropylene molded body, it is necessary to perform an etching treatment at 65 to 70 ° C. for 10 to 15 minutes using a chromic acid bath (mixed solution of chromium trioxide and sulfuric acid) after the degreasing treatment. Yes, wastewater contains toxic hexavalent chromate ions. For this reason, the process of neutralizing and precipitating the hexavalent chromate ions after reducing them to trivalent ions is essential, and there is a problem during wastewater treatment.

このように現場での作業時の安全性や廃水による環境への影響を考慮すると、クロム浴を使用したエッチング処理をしないことが望ましいが、その場合には、ABS樹脂等から得られる成形体へのメッキ層の密着強度を高めることができないという問題がある。
特開2003−82138号公報
In this way, in consideration of safety during work at the site and the environmental impact of wastewater, it is desirable not to perform etching using a chromium bath, but in that case, to a molded body obtained from ABS resin, etc. There is a problem that the adhesion strength of the plating layer cannot be increased.
JP 2003-82138 A

本発明は、樹脂成形体とメッキ層の密着強度が高く、外観も美しいメッキ樹脂成形体と、クロム酸等によるエッチング処理を不要とすることができる、前記メッキ樹脂成形体の製造法を提供することを課題とする。   The present invention provides a plated resin molded body having a high adhesion strength between the resin molded body and the plating layer and having a beautiful appearance, and a method for producing the plated resin molded body that can eliminate the etching treatment with chromic acid or the like. This is the issue.

本発明者は、熱可塑性樹脂に対して、キレート化剤等を配合して樹脂成形体にすることで、クロム酸のような重金属を含む酸によるエッチング処理なしでも樹脂成形体とメッキ層との密着強度を飛躍的に高められることを見出し、本発明を完成した。   The inventor blends a chelating agent and the like into a thermoplastic resin to form a resin molded body, so that the resin molded body and the plating layer can be formed without etching using an acid containing a heavy metal such as chromic acid. The present inventors have found that the adhesion strength can be dramatically increased and completed the present invention.

本発明は、上記課題の解決手段として、熱可塑性樹脂及びキレート化剤を含有する樹脂成形体の表面に金属メッキ層を有するメッキ樹脂成形体であり、樹脂成形体が重金属を含む酸によるエッチング処理がされていないものであるメッキ樹脂成形体を提供する。   The present invention provides a plating resin molded body having a metal plating layer on the surface of a resin molded body containing a thermoplastic resin and a chelating agent as a means for solving the above problems, and the resin molded body is etched with an acid containing a heavy metal. Provided is a plated resin molded article that has not been damaged.

本発明は、上記課題の他の解決手段として、請求項1〜7のいずれかに記載のメッキ樹脂成形体の製造法であり、熱可塑性樹脂と少なくともキレート化剤を含む樹脂成形体を脱脂処理する工程と、無電解メッキ工程とを具備しており、重金属を含む酸によるエッチング工程を含まないメッキ樹脂成形体の製造法を提供する。   The present invention provides a method for producing a plated resin molded article according to any one of claims 1 to 7 as another means for solving the above-mentioned problems, and degreasing a resin molded article containing a thermoplastic resin and at least a chelating agent. And a method for producing a plated resin molded body that includes an electroless plating step and does not include an etching step using an acid containing a heavy metal.

本発明のメッキ樹脂成形体は、クロム酸、過マンガン酸カリウム等の重金属を含む酸によるエッチング処理を経ていないが、高い密着強度のメッキ層を有している。また、クロム酸等の重金属を含む酸によるエッチング処理をしないので、廃水処理が容易であり、重金属による環境汚染がない。   The plated resin molded article of the present invention is not subjected to an etching treatment with an acid containing a heavy metal such as chromic acid or potassium permanganate, but has a plating layer with high adhesion strength. In addition, since the etching treatment with an acid containing heavy metal such as chromic acid is not performed, waste water treatment is easy and there is no environmental pollution due to heavy metal.

In particular, bumpers, emblems, wheel caps, interior parts Suitable for automotive parts such as exterior parts.

次に、本発明のメッキ樹脂成形体の製造法を工程毎に説明する。本発明の製造法は、脱脂処理する工程と無電解メッキ工程とを有するもので、前記2つの工程間に少なくとも触媒付与液で処理する工程を具備することが望ましく、更に必要に応じて、当業者によりなされる通常の処理工程を適宜付加することができる。   Next, the manufacturing method of the plating resin molding of this invention is demonstrated for every process. The production method of the present invention includes a degreasing process and an electroless plating process, and preferably includes a process of treating with at least a catalyst-providing liquid between the two processes. Ordinary processing steps performed by a trader can be added as appropriate.

まず、熱可塑性樹脂とキレート化剤、水溶性物質、界面活性剤等を含む樹脂成形体を脱脂処理する。なお、樹脂成形体は射出成形等の公知の方法により、用途に適した所望形状に成形して得る。   First, a resin molded body containing a thermoplastic resin, a chelating agent, a water-soluble substance, a surfactant and the like is degreased. The resin molded body is obtained by molding into a desired shape suitable for the application by a known method such as injection molding.

脱脂処理は、水酸化ナトリウム、炭酸ナトリウム等のアルカリ又は硫酸、炭酸等の酸を含有する界面活性剤水溶液により行う。本発明では、この脱脂処理後、無電解メッキ工程又は他の工程に移行することができ、メッキ層の密着強度を高めるための粗面化処理となるクロム酸、過マンガン酸カリウム等の重金属(本発明ではクロム、マンガン等)を含む酸によるエッチングエッチング工程は不要である。   The degreasing treatment is performed with an aqueous surfactant solution containing an alkali such as sodium hydroxide or sodium carbonate or an acid such as sulfuric acid or carbonic acid. In this invention, after this degreasing process, it can transfer to an electroless-plating process or another process, and becomes heavy metal (such as chromic acid and potassium permanganate) which becomes a roughening process for increasing the adhesion strength of the plating layer. In the present invention, an etching / etching step using an acid containing chromium, manganese, etc.) is unnecessary.

脱脂処理後、例えば、水洗工程、触媒付与液で処理する工程、水洗工程、活性化液で処理する工程(活性化工程)及び水洗工程を行うことができる。なお、触媒付与液で処理する工程と活性化液で処理する工程は、同時に行うことができる。   After the degreasing treatment, for example, a water washing step, a step of treating with a catalyst application liquid, a water washing step, a step of treating with an activation liquid (activation step) and a water washing step can be performed. In addition, the process with a catalyst provision liquid and the process with an activation liquid can be performed simultaneously.

触媒付与液による処理は、例えば、塩化錫(20〜40gl−1)の35%塩酸溶液(10〜20mgl−1)中、室温で1〜5分程度浸漬する。活性化液による処理は、塩化パラジウム(0.1〜0.3gl−1)の35%塩酸溶液(3〜5mgl−1)中、室温で1〜2分浸漬する。 The treatment with the catalyst-imparting solution is, for example, immersed in a 35% hydrochloric acid solution (10 to 20 mgl −1 ) of tin chloride (20 to 40 gl −1 ) at room temperature for about 1 to 5 minutes. In the treatment with the activation liquid, immersion is performed in a 35% hydrochloric acid solution (3 to 5 mgl −1 ) of palladium chloride (0.1 to 0.3 gl −1 ) at room temperature for 1 to 2 minutes.

その後、1回又は2回以上の無電解メッキ工程を行う。メッキ浴は、ニッケル、銅、コバルト、ニッケル−コバルト合金、金等と、ホルマリン、次亜リン酸塩等の還元剤を含むものを用いることができる。メッキ浴のpHや温度は、使用するメッキ浴の種類に応じて選択する。   Thereafter, one or more electroless plating steps are performed. As the plating bath, one containing nickel, copper, cobalt, nickel-cobalt alloy, gold and the like and a reducing agent such as formalin and hypophosphite can be used. The pH and temperature of the plating bath are selected according to the type of plating bath used.

無電解メッキ後に更にメッキ処理をする場合、酸又はアルカリによる活性化処理の後、銅等による電気メッキ工程を付加することもできる。   In the case of further plating after electroless plating, an electroplating step using copper or the like can be added after the activation treatment with acid or alkali.

本発明のメッキ樹脂成形体において、熱可塑性樹脂成形体と金属メッキ層との密着強度が高くなることのメカニズムの一つは、本願出願時では以下のとおりであると推定される。   In the plated resin molded body of the present invention, one of the mechanisms by which the adhesion strength between the thermoplastic resin molded body and the metal plating layer is increased is estimated as follows at the time of filing this application.

本発明の熱可塑性樹脂成形体に対して、酸等による接触処理をした際、吸水率の良い熱可塑性樹脂成形体の表面層が膨潤して膨潤層が形成される。そして、この膨潤層に触媒成分が浸透して行き、この触媒成分を核として、メッキ金属が核に付着・成長して、ネットワーク状の立体構造を形成する。このようにして膨潤層内部からメッキが成長して行く結果、成形体表面に高い密着強度を有する金属メッキ層が形成されるものと考えられる。また、この過程において、樹脂成形体に含まれるキレート化剤がメッキ金属の捕捉を促進するように作用するものと考えられる。   When the thermoplastic resin molded article of the present invention is subjected to contact treatment with an acid or the like, the surface layer of the thermoplastic resin molded article having a good water absorption rate swells to form a swollen layer. Then, the catalyst component penetrates into the swelling layer, and with this catalyst component as a nucleus, the plating metal adheres and grows on the nucleus to form a network-like three-dimensional structure. As a result of the plating growing from the inside of the swelling layer in this way, it is considered that a metal plating layer having high adhesion strength is formed on the surface of the molded body. In this process, it is considered that the chelating agent contained in the resin molded body acts to promote the capture of the plated metal.

従来、メッキ層の密着強度を高めるためには、高濃度の酸又は塩基を用いたエッチング処理により、樹脂成形体の表面を粗くすることが望ましいとされていたものであるが、本発明では、低濃度の酸又は塩基による接触処理工程を付加することにより、粗面化処理をすることなく、金属メッキ層の密着強度を高めることができるものであり、作業時の安全性も高められ、廃液処理も容易になるという効果も合わせて得ることができる。   Conventionally, in order to increase the adhesion strength of the plating layer, it was desirable to roughen the surface of the resin molded body by etching using a high concentration acid or base, but in the present invention, By adding a contact treatment step with a low-concentration acid or base, the adhesion strength of the metal plating layer can be increased without roughening treatment, and the safety during work is also improved, and the waste liquid The effect that the processing becomes easy can also be obtained.

以下に、実施例に基づいて本発明をより詳細に説明するが、本発明はこれらの実施例によって限定されるものではない。なお、実施例及び比較例で行ったメッキ層の密着性試験と、使用した成分の詳細は下記のとおりである。   Hereinafter, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples.
