Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional method for giving a feeling of metallic gloss by painting enables an appearance of the total reflection of a metallic gloss not to be obtained although a metallic appearance can surely be obtained by paining alone and prevents a paint film from being peeled off in boiling water testing or sweat adhesion testing. <P>SOLUTION: In a decorative object in which a clear paint film is formed on a member with plating applied on a metal substrate, the surface of the plating membrane is coated with a mercapto type silane coupling agent, and a polyester adhesive layer and the clear paint film are formed on the surface of the silane coupling agent. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、筆記具や化粧具等の筒状の軸形状を有する装飾体に関するものであり、特に金属光沢を有し、かつ指紋が目立ちにくい装飾性に優れた装飾体に関するものである。   The present invention relates to a decorative body having a cylindrical shaft shape, such as a writing instrument or a cosmetic, and particularly relates to a decorative body having a metallic luster and excellent in decorativeness in which fingerprints are not noticeable.

従来筆記具等に使用される金属製の軸体は、銅合金等の素材にめっき処理または塗装処理などの単独の処理をして使用されていた。さらに銅合金等の素材にフラッシュ金めっき皮膜を形成し、その後、クリアー塗装を行い使用している例もある。   Conventionally, a metal shaft used for a writing instrument or the like has been used by subjecting a material such as a copper alloy to a single treatment such as plating or painting. In addition, there is an example in which a flash gold plating film is formed on a material such as a copper alloy, and then a clear coating is applied.

めっき処理は、めっき皮膜の構成および厚さによっては耐食性が悪く、樹脂膜によるコーティングを行っている。コーティングの色調は、めっき皮膜の金属光沢および色調を生かすため無色透明である。めっき皮膜の表面と塗装の密着を確保するためクロメート処理やシランカップリング剤の処理(特許文献1)が行われている。
また、めっき処理の金属を用いずメタリックの外観を塗装で表現する方法も存在する。これはアルミフレークなどの光輝性の顔料を塗膜中に分散し塗装するものである。フレークが均一に薄く並ぶことにより、金属調の様々な色調の装飾体が得られる(特許文献2)。

The plating treatment has poor corrosion resistance depending on the structure and thickness of the plating film, and is coated with a resin film. The color tone of the coating is colorless and transparent in order to take advantage of the metallic luster and color tone of the plating film. Chromate treatment and silane coupling agent treatment (Patent Document 1) are performed to ensure adhesion between the surface of the plating film and the coating.
There is also a method of expressing a metallic appearance by painting without using a metal for plating treatment. In this method, a bright pigment such as aluminum flake is dispersed in a coating film and applied. By arranging the flakes uniformly and thinly, decorative bodies with various metallic tones can be obtained (Patent Document 2).
JP 2004-203014 A Japanese Patent Laid-Open No. 2003-21594

しかしながら、特許文献1のめっき皮膜の表面に単にシランカップリング処理をしてクリアー塗装を形成した従来構成においては、製品を沸騰水に入れて煮沸したり、汗を付着させ70℃,95%,4時間条件で促進試験を行なったりすると、塗膜がはく離してしまうという問題点があった。また、アクリルシリコーン樹脂とアルコキシシラン、シランカップリング剤の混合系で比率の管理が難しく反応が設計通り進まないと品質の低下が免れないものである。   However, in the conventional configuration in which the surface of the plating film of Patent Document 1 is simply subjected to a silane coupling treatment to form a clear coating, the product is boiled in boiling water, or sweat is attached to 70 ° C., 95%, When the acceleration test was performed under the 4-hour condition, there was a problem that the coating film peeled off. In addition, it is difficult to manage the ratio in a mixed system of acrylic silicone resin, alkoxysilane, and silane coupling agent, and the deterioration of quality cannot be avoided unless the reaction proceeds as designed.

また、特許文献2の塗装による金属光沢感を付与する従来方法は、確かに塗装のみでメタリックの外観が得られ、沸騰水試験や汗の付着試験で塗膜がはく離することはないが、金属光沢の全反射の外観は得られないという問題があった。   In addition, the conventional method of imparting a metallic luster by painting in Patent Document 2 can certainly give a metallic appearance only by painting, and the coating film does not peel off in a boiling water test or a sweat adhesion test. There was a problem that a glossy total reflection appearance could not be obtained.

本発明は、金属光沢を有し、かつ、指紋が付着しても目立ちにくい装飾体を提供することを目的とし、かつ、シランカップリング剤によりめっき皮膜の表面の表面改質を行い、ポリエステル系の透明性の高い接着剤層をめっき皮膜の表面とクリアー塗膜層の間に介在させることにより、沸騰水試験や汗の付着試験においても塗膜がはく離することがなく、かつ、めっき皮膜の金属光沢と色調を損なうことのない装飾体が得られることを見いだし、本発明を完成させたものである。すなわち、本発明は、金属基材上にめっき皮膜を形成した部材にクリアー塗装膜を形成した装飾体において、前記めっき皮膜の表面にメルカプト系のシランカップリング剤を塗布し、そのメルカプト系のシランカップリング剤の表面にポリエステル系接着剤層と、クリアー塗装膜を形成したことを要旨とするものである。   An object of the present invention is to provide a decorative body having a metallic luster and not noticeable even if fingerprints are attached, and surface modification of the surface of the plating film with a silane coupling agent, By interposing a highly transparent adhesive layer between the surface of the plating film and the clear coating layer, the coating film does not peel off even in a boiling water test or a sweat adhesion test. The inventors have found that a decorative body that does not impair the metallic luster and color tone can be obtained, and the present invention has been completed. That is, the present invention relates to a decorative body in which a clear coating film is formed on a member on which a plating film is formed on a metal substrate, a mercapto silane coupling agent is applied to the surface of the plating film, and the mercapto silane The gist is that a polyester adhesive layer and a clear coating film are formed on the surface of the coupling agent.

本発明によれば、特に煩雑な工程を経ることなく低コストで金属光沢の外観で、かつ、指紋が付着しても目立ちにくく、かつ耐久性の高い装飾体を得ることが出来る。   According to the present invention, it is possible to obtain a decorative body that is low in cost and has a metallic luster appearance, is not noticeable even when fingerprints are attached, and has high durability without going through a particularly complicated process.

本発明の装飾体の例を図1に示す。金属基材1は、銅合金であり黄銅や洋白、リン青銅等が用いられる。切削やプレス加工が容易でめっき皮膜が形成でき、安価な材料であれば良く、特に限定されるものではない。
めっき皮膜2は、公知の方法で形成すれば良く特に限定されるものではない。一例を挙げれば溶剤脱脂の後、アルカリ脱脂、酸活性、光沢ニッケル、そして最後に装飾めっき(金や金合金、パラジウムやパラジウム合金、銀や銀合金、ニッケルやニッケル合金等)を形成する。めっき皮膜の厚さおよびめっき層の構成は、特に限定されるものではない。
めっき処理後、変色防止や耐食性向上のためクロメート処理を施すことは、より好ましい。
メルカプト系のシランカップリング剤層3は、スプレー塗装法、ディッピング法等の方法で形成される。このメルカプト系のシランカップリング剤層は、めっき皮膜の表面の表面改質を行い、この後に形成されるポリエステル系の接着剤層の濡れ性を改善するために形成される。メルカプト系シランカップリング剤は、3−メルカプトプロピルメチルジメトキシシラン、3−メルカプトプロピルトリメトキシシラン、3−メルカプトトリエトキシシラン等が用いられ、それぞれ単独あるいは2種類以上を混合して用いることが出来る。
ポリエステル系接着剤層4は、スプレー塗装法で形成される。薄く均一に形成できるからである。このポリエステル接着剤層4は、基材とクリアー塗膜の間に介在しクリアー塗膜が基材に強固に密着するように形成するものである。ポリエステル接着剤層4は、めっき皮膜の表面に拡散浸透する効果があることから熱により溶解するタイプがより好ましいが、これに限定されるものではない。ポリエステル系接着剤層に用いられる材料は、ポリエステルポリオールからなる接着剤であり、特に限定されるものではない。ウレタン変性されたものやメラミン樹脂を少量混合したものも用いることが出来る。硬化後の皮膜が特に耐水性や耐汗性の必要な場合は、イソシアネート系の硬化剤(触媒)を用いて塗膜を完全に架橋させるとなお好ましい。
クリアー塗膜層5は、アクリル系、アクリル−ウレタン系の無色透明のクリアーを用いる。アクリル系は、熱による黄変が少なくかつ透明性が高く、熱硬化型を用いれば生産性も良くすることが出来る。クリアー塗膜層5は、スプレー塗装法で形成される。薄く均一に形成できるからである。
An example of the decorative body of the present invention is shown in FIG. The metal base material 1 is a copper alloy, and brass, white, phosphor bronze, or the like is used. Any material can be used as long as it is easy to cut and press, can form a plating film, and is inexpensive, and is not particularly limited.
The plating film 2 may be formed by a known method and is not particularly limited. For example, after solvent degreasing, alkali degreasing, acid activity, bright nickel, and finally decorative plating (gold or gold alloy, palladium or palladium alloy, silver or silver alloy, nickel or nickel alloy, etc.) are formed. The thickness of the plating film and the configuration of the plating layer are not particularly limited.
It is more preferable to perform a chromate treatment after the plating treatment to prevent discoloration and improve corrosion resistance.
The mercapto-based silane coupling agent layer 3 is formed by a method such as spray coating or dipping. This mercapto-based silane coupling agent layer is formed to modify the surface of the plating film and to improve the wettability of the polyester-based adhesive layer formed thereafter. As the mercapto-based silane coupling agent, 3-mercaptopropylmethyldimethoxysilane, 3-mercaptopropyltrimethoxysilane, 3-mercaptotriethoxysilane, or the like is used, and each can be used alone or in combination of two or more.
The polyester adhesive layer 4 is formed by a spray coating method. This is because it can be thinly and uniformly formed. The polyester adhesive layer 4 is formed so as to be interposed between the base material and the clear coating film so that the clear coating film is firmly adhered to the base material. The polyester adhesive layer 4 is more preferably of a type that dissolves by heat because it has the effect of diffusing and penetrating the surface of the plating film, but is not limited thereto. The material used for the polyester-based adhesive layer is an adhesive made of polyester polyol, and is not particularly limited. Those modified with urethane and those mixed with a small amount of melamine resin can also be used. When the film after curing requires water resistance or sweat resistance in particular, it is more preferable to completely crosslink the film using an isocyanate curing agent (catalyst).
The clear coating layer 5 uses an acrylic or acrylic-urethane colorless and transparent clear. Acrylic resin has little yellowing due to heat and is highly transparent. If a thermosetting type is used, productivity can be improved. The clear coating film layer 5 is formed by a spray coating method. This is because it can be thinly and uniformly formed.
