Description
【０００１】0001
本考案は、金属板からなる芯材と、これを被包する合成樹脂層とからなる複合 材で形成された雨樋の改良技術に関する。 This invention is a composite material consisting of a core material made of a metal plate and a synthetic resin layer encasing it. Concerning technology for improving rain gutters made of wood.
【０００２】0002
硬質塩化ビニル樹脂等の合成樹脂からなる雨樋は、使用中の環境温度の変化に より大きく伸縮し変形するので、機能上、外観上好ましくない結果を招くという 欠点があった。 Rain gutters made of synthetic resin such as hard PVC resin are resistant to changes in environmental temperature during use. Because it expands, contracts, and deforms to a greater extent, it causes unfavorable results in terms of function and appearance. There were drawbacks.
【０００３】 従来、この欠点を解決するために、金属板や金網を合成樹脂の中に入れた複合 材を素材として雨樋を成形し、物理的な力で熱変形を少なくすると共に、合成樹 脂だけでは不十分であった機械的強度を向上させる試みがなされている。例えば 、実公昭６３−２６５０６号公報には、多数の貫通孔を穿設した金属板からなる 芯材の表面に、接着剤層をこれが貫通孔内に入るように塗布し、この接着剤層を 介して合成樹脂層を被覆してなる雨樋について記載されている。0003 Conventionally, in order to solve this drawback, composite materials were used in which metal plates or wire mesh were placed inside synthetic resin. Rain gutters are molded using wood to reduce thermal deformation using physical force, and synthetic wood is used to form rain gutters. Attempts have been made to improve mechanical strength, which was insufficient with fat alone. for example , Utility Model Publication No. 63-26506 discloses a metal plate made of a metal plate with a large number of through holes. Apply an adhesive layer to the surface of the core material so that it enters the through hole, and then This document describes a rain gutter that is coated with a synthetic resin layer through a synthetic resin layer.
【０００４】 この雨樋は、このような構成とすることにより、貫通孔に接着剤層が食い込ん で、接着剤層が芯材に強固に接着すると共に、この接着剤層はその上に形成され た合成樹脂層とも強固に接着するので、結果的に芯材層と合成樹脂層とが一体化 されるのであり、この技術では、接着剤層は一種のプライマーとしての機能だけ でなく、貫通孔を利用しての一種のアンカーとしての機能を果たしている。0004 By configuring this rain gutter in this way, the adhesive layer digs into the through holes. The adhesive layer firmly adheres to the core material, and this adhesive layer is formed on top of it. Since it firmly adheres to the synthetic resin layer, the core material layer and synthetic resin layer become integrated. In this technology, the adhesive layer only functions as a kind of primer. Rather, it functions as a kind of anchor using the through hole.
【０００５】[0005]
このように、貫通孔を通して内外の接着剤層を結合させれば、芯材層と接着剤 層とは強固に接着するが、このような孔明き金属板を用いると、金属製芯材とし て要求される補強の効果を充分に発揮し得ないという問題があり、補強の充分な 効果を得ようとして孔数を減らしたり、孔の大きさを小さくしたりすると、芯材 層と合成樹脂層との界面の接着性に劣るということになって、その所期の効果を 得ることができないという関係にあり、思うような特性を具備したものが得られ ないという問題があった。 In this way, if the inner and outer adhesive layers are combined through the through hole, the core material layer and adhesive However, if such a perforated metal plate is used, it will not work as a metal core material. There is a problem that the required reinforcement effect cannot be fully demonstrated. If you reduce the number of holes or reduce the size of the holes in an attempt to obtain an effect, the core material The adhesiveness of the interface between the layer and the synthetic resin layer was poor, and the desired effect was not achieved. There is a relationship in which it is impossible to obtain something with the desired characteristics. The problem was that there was no.
【０００６】 又、一口に接着剤といっても金属と合成樹脂層との両方に対しての接着性が要 求され、両者の組合せ如何により、最適の接着剤を見出すことは容易ではなく、 この点に関して上記実公昭６３−２６５０６号公報には、何らの記載もなされて いない。[0006] Also, even though it is just an adhesive, it must have adhesion to both metal and synthetic resin layers. It is not easy to find the optimal adhesive depending on the combination of the two. Regarding this point, the above-mentioned Utility Model Publication No. 63-26506 does not contain any description. not present.
【０００７】 本考案者等は種々工夫した結果、接着剤として或る特定のものを用い、且つ合 成樹脂層を形成する樹脂として、同じく特定のものを用いれば、孔明き金属板を 用いなくとも、芯剤層と合成樹脂層とを強固に接着したものが得られることを知 見して本考案を完成するに到ったのである。[0007] As a result of various efforts, the inventors of the present invention used a certain adhesive as an adhesive, and If a specific resin is used to form the resin layer, a perforated metal plate can be formed. It is known that even without using a core material layer and a synthetic resin layer, a product with strong adhesion can be obtained. After looking at this, I was able to complete this idea.
【０００８】 即ち、本考案は、屋外において長期間暴露状態になっても、金属製芯材や内層 の合成樹脂層に対し、外層の塩化ビニル樹脂層が剥離することのない雨樋を提供 することを目的としてなされたものである。[0008] In other words, the present invention can protect the metal core material and inner layer even if exposed outdoors for a long time. Provides rain gutters with no peeling of the outer vinyl chloride resin layer compared to the synthetic resin layer. It was done for the purpose of

本考案は、金属板からなる芯材の表面に、カルボニル基を有する合成樹脂層が 被覆され、さらにこの合成樹脂層の表面に塩化ビニル系樹脂層が被覆された構成 となされている。カルボニル基を有する合成樹脂層は金属板との接着性が良く、 又、通常塩化ビニル系樹脂との相溶性に優れているので、塩化ビニル系樹脂との 接着性にも優れている。従って、芯材層と塩化ビニル系樹脂層とがこのカルボニ ル基を有する合成樹脂層を介して強固に接着し、屋外において長期間暴露状態に なっても、金属製芯材と塩化ビニル系樹脂層とが剥離することがなく、防錆性が 付与される。又、孔明き金属板を使用しないので、芯材の補強効果を犠牲にする ことなく、耐熱変形性を具備した雨樋を得ることができる。 This invention consists of a synthetic resin layer containing carbonyl groups on the surface of a core material made of a metal plate. A structure in which the surface of this synthetic resin layer is further coated with a vinyl chloride resin layer. It is said that The synthetic resin layer with carbonyl groups has good adhesion to metal plates, In addition, it has excellent compatibility with vinyl chloride resins, so it can be used easily with vinyl chloride resins. It also has excellent adhesive properties. Therefore, the core material layer and the vinyl chloride resin layer are Strongly adheres through a synthetic resin layer containing ru groups, and can withstand long-term exposure outdoors. The metal core material and vinyl chloride resin layer will not peel off even if Granted. Also, since a perforated metal plate is not used, the reinforcing effect of the core material is sacrificed. It is possible to obtain a rain gutter having heat deformation resistance without any heat deformation.
