Abstract

<P>PROBLEM TO BE SOLVED: To provide a bonding method that achieves a predetermined mechanical strength, beautiful appearance and improvement in workability in an operation of bonding through a combination of a carbon material, a glass fiber material, an unsaturated resin with a curing agent and the like without any machining. <P>SOLUTION: A metal is bonded to a resin material or a different metal by a bonding method comprising a series of steps of subjecting one metal to be bonded to surface treatment, coating a carbon material on the surface of the surface-treated metal, further coating thereon an unsaturated resin mixed with a curing agent, laminating one to the other and then drying, and optionally performing finishing. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

Field of Invention

本発明は、一定の手法で混ぜ合わせ接着効果向上を可能にする材料を介して、樹脂系素材叉は異種金属と金属を接合する方法に関する。The present invention relates to a method of joining a metal or a dissimilar metal to a metal via a material that can improve the mixing and adhesion effect by a certain method.

従来の樹脂系素材叉は異種金属と金属の接合は、下記１）、２）の方法が主流である。
１）、異種金属と金属との結合の場合
▲１▼溶接し、その隙間にシ−ル材を充填する
▲２▼リベット止めし、その隙間にシ−ル材を充填する
▲３▼接着材による接合（但しこの方法は、接着強度が低い）
２）、樹脂系素材と金属との結合の場合
▲１▼リベット止めし、その隙間にシ−ル材を充填する
▲２▼接着材による接合（但しこの方法は、接着強度が低い）The conventional methods 1) and 2) are mainly used for joining a resin material or a dissimilar metal to a metal.
1) In case of bonding between dissimilar metals and metal (1) Welding and filling the gap with seal material (2) Riveting and filling the gap with seal material (3) Adhesive (However, this method has low adhesive strength)
2) In case of bonding resin material and metal (1) Riveting and filling the gap with seal material (2) Bonding with adhesive (however, this method has low adhesive strength)

Problems to be solved by the invention

従来の接合方法は、作業技術が要求され、且つ作業性が悪い。叉接合後の接合部の仕上がりが悪く、継ぎ目も必ずヒビ割れを起こすという問題点があった。The conventional joining method requires work technology and has poor workability. There was a problem that the finished part of the joint after fork joint was poor and the seam was always cracked.

本発明は、機械的な加工や特殊な熟練技術無しで、異種金属と金属叉は樹脂系素材と金属の接合を簡略化し、且つその接合の機械的強度、美観およびその作業性の向上を目的とする。The present invention aims to simplify the joining of dissimilar metals and metals or resin-based materials and metals without mechanical processing or special skill, and to improve the mechanical strength, aesthetics and workability of the joining. And

Means to solve the problem

接合しようとする一方の金属を表面処理し、その表面にカ−ボン系素材を被覆させる。さらに不飽和樹脂と硬化剤を混ぜてその上に塗り、お互いを張り合わせ乾燥させ、適宜仕上げ加工を施す一連の接合方法One metal to be joined is surface-treated, and a carbon-based material is coated on the surface. Furthermore, a series of joining methods in which an unsaturated resin and a curing agent are mixed and applied on top of each other, bonded together, dried, and appropriately finished.

図１は、金属薄板１の表面を紙やすり等で目荒らしし、その金属の表面に処理剤２（錆止め）をハケまたはスプレーガンで塗ったもの。図２は、その後ある一定時間強制乾燥させ、その金属表面にカーボン系素材のパテ３を一定の厚みで塗布し、再び強制乾燥したもの。FIG. 1 shows the surface of a thin metal plate 1 that is roughened with a sandpaper or the like, and the treatment agent 2 (rust prevention) is applied to the surface of the metal with a brush or a spray gun. FIG. 2 shows a case where forced drying is performed for a certain period of time, a carbon-based putty 3 is applied to the metal surface with a certain thickness, and then forced-dried again.

図３は、更にその表面に硬化剤と混ぜた不飽和樹脂４をハケまたはスプレーガンで塗布し、それにガラス繊維系のファイバーマット５またはアルミ板６を貼り付けたもの。
この工程を２〜３回繰り返し（ファイバーマットを２〜３層にする）完成品とする。FIG. 3 shows a state in which an unsaturated resin 4 mixed with a curing agent is applied to the surface with a brush or a spray gun, and a glass fiber-based fiber mat 5 or an aluminum plate 6 is attached thereto.
This process is repeated 2 to 3 times (the fiber mat is made into 2 to 3 layers) to obtain a finished product.

The invention's effect

この技術によって樹脂系素材叉は異種金属と金属の接合方法が確立でき、機械的強度と美観も向上し、自動車業界や建築業界での利用が大幅に向上することが想定できる。（特に軽量化、リサイクル化に効果大）。また他方面の分野に普及が想定できる。With this technology, it is possible to establish a method for joining resin-based materials or dissimilar metals to metals, and to improve mechanical strength and aesthetics, and it can be assumed that usage in the automobile industry and the construction industry will be greatly improved. (Especially effective for weight reduction and recycling). In addition, it can be assumed to be popular in the other field.
