キを施す方法及び表面処理製品に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method and surface for applying chromium plating to the outer peripheral surface of a long molded body made of resin, such as a roll made of resin or fiber-reinforced resin. It concerns processed products.
以下２本発明を炭素繊維強化樹脂製のロールを例にとっ
て説明する。The following two aspects of the present invention will be explained using a roll made of carbon fiber reinforced resin as an example.
フィルム、箔９紙などの軽薄材料をライン中で搬送する

チックメッキとして知られている方法を適用すればよい
と考えられる。In order to convey light and thin materials such as films and paper foils in a line, rolls with a small moment of inertia and little deflection are required, so rolls with aluminum shells have traditionally been used. In recent years, carbon fiber reinforced resins have begun to be used. These rolls are often subjected to various surface treatments such as rubber lining and resin lining depending on the purpose, and in some cases, it is also desired to perform hard chrome plating. In order to apply hard chromium plating to the outer peripheral surface of a carbon fiber reinforced resin roll, it is considered that a method generally known as plastic plating may be applied.
しかしながら、一般のプラスチックメッキは、樹脂面を

には法線、剪断両方向の外力が大なり小なり加わり、上
記した従来のプラスチックメッキによって施したメッキ
層では付着力が不足し、短期間に損傷を生じてしまい１
実用に適さないという問題があった。However, general plastic plating requires a degreasing process to degrease the resin surface, a chemical ethoching process to make the resin surface hydrophilic, a sensitization process to adsorb metal salts with reducing power such as stannous chloride, and palladium Complex processes such as an activation process by liquid treatment, an electroless copper plating or nickel metal plating process, an electrolytic copper plating or nickel metal plating process, and an electrochrome plating process are required, resulting in extremely poor productivity. Moreover, the adhesion of the formed plating layer is extremely low (1) and inferior to the adhesion of ordinary adhesives. Generally, external forces in both normal and shear directions are applied to the surface of rolls used to transport light and thin materials, and the plating layer applied using the conventional plastic plating described above lacks adhesion and is damaged in a short period of time. 1
There was a problem that it was not suitable for practical use.
また、従来より、樹脂に対するメッキ層の付着力を改善
するための各種方案が工夫されており９例えば。Furthermore, various methods have been devised to improve the adhesion of the plating layer to the resin.9 For example.
特開昭６０−７７９７７号は金属粉体を含有する組成物
の層を、又、特開昭６１−２１７５６６号は金属溶射層
を、メッキの足掛りのための前処理として施すものであ
る。しかし、これらもやはり連続した金属面へのメッキ
ではないため、メッキに当たっては高度の技術を要する
ものであり、相変わらず難題であることを免れない。JP-A-60-77977 discloses a layer of a composition containing metal powder, and JP-A-61-217,566 applies a sprayed metal layer as a pretreatment for plating. However, since these methods do not involve plating a continuous metal surface, plating requires a high level of skill and remains a difficult task.
炭素繊維強化樹脂製ロールのロールフェイスを、薄肉金
属円筒でぴったりと囲繞し９表面が完全に金属化できれ
ば、常法による付着性のよいメッキが得られる筈であり
、又、炭素繊維強化樹脂ロールの軽量性も損なわれない
と考えられる。しかし、薄肉金属円筒を。If the roll face of a carbon fiber reinforced resin roll is tightly surrounded by a thin metal cylinder and the surface is completely metallized, it should be possible to obtain plating with good adhesion using a conventional method. It is thought that the lightness of the structure will not be impaired. However, a thin-walled metal cylinder.
その内径が炭素繊維強化樹脂製ロールの外面にぴったり
嵌合できる寸法に調製することは極めて困難であり。It is extremely difficult to adjust the inner diameter to a size that allows it to fit perfectly onto the outer surface of the carbon fiber reinforced resin roll.
実用的ではない。例えば、金属管の内面を研削して樹脂
製ロールに嵌合し、その後、その外面を研削して薄肉化
することが考えられるが、精度のよい内面研削が特に長
尺品に於いて至難且つ高価であることを考えれば、およ
そ現実的ではない。Not practical. For example, it is conceivable to grind the inner surface of a metal tube, fit it into a resin roll, and then grind the outer surface to make the tube thinner, but accurate internal grinding is extremely difficult, especially for long products. Considering how expensive it is, it is hardly practical.
本発明はかかる従来の問題点を解決すべくなされたもの

The purpose is to provide a processing method and products manufactured thereby.

そのシートの両終端同志を接合することにより。As a result of intensive studies to solve the above problems, the inventors of the present invention surrounded the outer peripheral surface of the resin molded body with a thin metal sheet,
By joining both ends of the sheet together.

すなわち５本発明は、樹脂製成型体の外周面を薄肉金属

である。また、その成型体の形状は。In the present invention, the resin molded body is a molded body made of only one or more types of resin, or one containing various additives and R materials, or a fiber-reinforced resin reinforced with carbon fibers, etc. Even if the above-mentioned resin is composited with a core material such as metal, any material in which chromium plating is applied on the resin is considered to be subject to the present invention. Also, what is the shape of the molded product?

A value of 0.1 to 0.2** is suitable. The material of the thin metal sheet I is also not limited, but from the viewpoint of marketability or suitability for the subsequent plating process, iron-based materials such as mild steel 2 stainless steel, nickel, and copper may be used.

くことがなく。After surrounding the outer peripheral surface of the resin molded body with a thin metal sheet,
Both ends are joined together. As a result, the thin metal sheet is formed into a cylindrical shape, and the resin molded body is fitted inside the cylindrical shape. At the time of this joining, by joining the two ends of the thin metal sheet with the resin molded body tightened, the tube material formed of the thin metal sheet can be molded into the resin molded body using the frictional force due to its own tightening force. Fixed and integrated with the body. If necessary, an adhesive may be interposed between the thin metal sheet and the outer peripheral surface of the resin molded body to bond them together. Adhesion may be done when surrounding the thin metal sheet,
Alternatively, after applying true melt adhesive in advance and joining both ends of the thin metal sheet to form a cylinder,
A melting method may also be used. In addition, when using an adhesive, the thin metal sheet is joined to the resin molded body by the adhesive, so the thin metal sheet can be molded into the resin molded body even without the tightening force of the cylinder material due to the thin metal sheet. without moving relative to the body.
従って薄肉金属シートの樹脂製成型体に対する締付力は
小さくてよい。Therefore, the tightening force of the thin metal sheet to the resin molded body may be small.

Electrolytic casting is a metal electrolytic deposition technology that can be used not only for plating, but also for plating and overlaying.Although it can be done with a special prescription, it is also possible to use the plating bath as is. . For example, as shown in FIG.
Preferably, the same type of metal is electrolytically deposited on the V-grooves provided at the abutting portions of the metal sheets 2.
