When laminating single-layer plates, if the resin surface of a single-layer plate is in contact with the metal surface or resin surface of another single-layer plate, adhesive lamination is performed using the thermal bonding method described above or an adhesive agent between the metal plate and the resin. To do. When the metal surface of a single-layer board contacts the metal surface of another single-layer board, it laminates | bonds together via an adhesive agent between metal plates.
２枚の金属板の間に樹脂を介在させてなる樹脂金属複合板を出発材として用いる場合も、公知の熱接着法を用いて樹脂を介して２枚の金属板に直接熱接着してもよいし、金属板と樹脂の間にさらに接着剤を介して接着してもよい。このようにして得られる樹脂金属複合板は、単層板として圧延してもよいし、後記するように複数の単層の樹脂金属複合板同士を樹脂を介して、または樹脂と接着剤を介して積層して樹脂金属複合積層板として圧延してもよい。 Even when a resin metal composite plate having a resin interposed between two metal plates is used as a starting material, it may be directly heat bonded to the two metal plates via a resin using a known thermal bonding method. Further, the metal plate and the resin may be further bonded via an adhesive. The resin-metal composite plate thus obtained may be rolled as a single-layer plate, or a plurality of single-layer resin-metal composite plates may be bonded to each other via a resin or a resin and an adhesive as will be described later. And laminated and rolled as a resin-metal composite laminate.
上記のように、本発明においては金属板と樹脂との接着に際して、公知の熱接着法や、接着剤を介して接着を行うことによって、下記に示す圧延において圧延率が高くとも比較的高強度の接着を得ることを目標とするが、比較的薄い金属板を用いてこの薄金属板に樹脂を被覆する場合は圧延率を低くすることができるので、金属板と樹脂との接着はそれほど高強度の接着は必要ではなく、圧延後の樹脂を容易に剥離可能な程度の接着力を有しておればよい。そのため、このような場合にはパラフィンのような物質を接着剤として用いて、薄い金属板に樹脂を被覆してもよい。 As described above, in the present invention, when the metal plate and the resin are bonded, by using a known thermal bonding method or bonding via an adhesive, relatively high strength is achieved even when the rolling rate is high in the rolling shown below. However, when a relatively thin metal plate is used to cover the resin with this thin metal plate, the rolling rate can be lowered, so the adhesion between the metal plate and the resin is very high. It is not necessary to have strong adhesion, and it is only necessary to have an adhesive force that can easily peel off the resin after rolling. Therefore, in such a case, a thin metal plate may be coated with a resin using a substance such as paraffin as an adhesive.
次に圧延方法について説明する。上記の出発材である樹脂被覆金属板、樹脂被覆金属積層板、樹脂金属複合板、樹脂金属複合積層板のいずれかを、通常の単スタンドミル、タンデムミル、リバースミルなどの圧延装置を用いて冷間圧延して極薄化する。以下、図面を参照しながら圧延方法を説明する。
樹脂被覆金属板の圧延方法としては、図１に示すように金属板２０の片面に樹脂１０を被覆してなる単層の樹脂被覆金属板１ａを１枚、圧延ロールを有する圧延装置に通して圧延する。このようにして樹脂被覆極薄金属板が得られる。
Next, the rolling method will be described. Using any of the above starting materials, such as a resin-coated metal plate, a resin-coated metal laminate plate, a resin-metal composite plate, and a resin-metal composite laminate plate, using a normal single stand mill, tandem mill, reverse mill, or other rolling device Cold rolling to make it extremely thin. Hereinafter, the rolling method will be described with reference to the drawings.
As a rolling method of the resin-coated metal plate, as shown in FIG. 1, a single-layer resin-coated
樹脂被覆金属積層板の圧延方法としては、図２に示すように金属板２０の両面に樹脂１０を被覆してなる樹脂被覆金属板（図中２ａで表示）を複数枚、および重ね合わせの最下部の樹脂被覆金属板として図１に示した金属板２０の両面に樹脂１０を被覆してなる単層の樹脂被覆金属板１ａを、図２に示すように金属面同士が当接することがないように重ね合わせて積層してなる樹脂被覆金属積層板３０を、圧延ロールを有する圧延装置に通して圧延する。または、図３に示すように、図１に示した金属板２０の両面に樹脂１０を被覆してなる単層の樹脂被覆金属板１ａを複数枚重ね合わせて積層してなる樹脂被覆金属積層板３０を、圧延ロールを有する圧延装置に通して圧延する。このようにして樹脂被覆極薄金属積層板が得られる。
As a rolling method of the resin-coated metal laminated plate, as shown in FIG. 2, a plurality of resin-coated metal plates (indicated by 2a in the figure) formed by coating the
樹脂金属複合板の圧延方法としては、図４に示すように２枚の金属板２０の間に樹脂１０を介在させてなる樹脂金属複合板４０を１枚、圧延ロールを有する圧延装置に通して圧延する。このようにして樹脂金属複合極薄板が得られる。
As a method for rolling a resin-metal composite plate, as shown in FIG. 4, one resin-metal composite plate 40 having a
樹脂金属複合積層板の圧延方法としては、図５に示すように図４に示した樹脂金属複合板４０を、樹脂１０ａを介して複数枚重ね合わせて積層してなる樹脂金属複合積層板５０を、圧延ロールを有する圧延装置に通して圧延する。このようにして樹脂金属複合極薄積層板が得られる。 As a rolling method of the resin-metal composite laminate, as shown in FIG. 5, a resin-metal composite laminate 50 formed by laminating a plurality of resin-metal composite plates 40 shown in FIG. And rolling through a rolling device having a rolling roll. In this way, a resin-metal composite ultrathin laminate is obtained.
図１〜図５に示した方法による樹脂被覆極薄金属板、樹脂被覆極薄金属積層板、樹脂金属複合極薄板、樹脂金属複合極薄積層板においては、圧延後の各金属板の厚さが０．１ｍｍ以下となるように圧延することが好ましい。厚さが０．１ｍｍを超える樹脂被覆極薄金属板や樹脂金属複合極薄板を得ることは可能であるが、これらの方法を用いずとも製造できる。圧下率を高めて圧延後の各金属板の厚さが０．０１ｍｍ未満の厚さの樹脂被覆極薄金属板、樹脂被覆極薄金属積層板、樹脂金属複合極薄板、樹脂金属複合極薄積層板を得ることは、樹脂が剥離したり樹脂に亀裂が生じたりするので困難である。このようにして製造された樹脂被覆極薄金属板、樹脂被覆極薄金属積層板、樹脂金属複合極薄板、樹脂金属複合極薄積層板においては、圧下率の増大に伴って金属板に対する樹脂の接着強度が低下するが、圧延後に樹脂のガラス転移温度以上の温度、好ましくは樹脂の結晶化温度以上の温度に加熱することにより、接着強度を上昇させることができる。 In the resin-coated ultrathin metal plate, resin-coated ultrathin metal laminate, resin-metal composite ultrathin plate, and resin-metal composite ultrathin laminate by the method shown in FIGS. 1 to 5, the thickness of each metal plate after rolling Is preferably rolled so as to be 0.1 mm or less. Although it is possible to obtain a resin-coated ultrathin metal plate or a resin-metal composite ultrathin plate having a thickness exceeding 0.1 mm, it can be produced without using these methods. Resin-coated ultra-thin metal plate, resin-coated ultra-thin metal laminate, resin-metal composite ultra-thin plate, resin-metal composite ultra-thin laminate with a thickness of less than 0.01 mm after rolling by increasing the rolling reduction Obtaining a plate is difficult because the resin peels off or cracks occur in the resin. In the resin-coated ultra-thin metal plate, resin-coated ultra-thin metal laminate, resin-metal composite ultra-thin plate, and resin-metal composite ultra-thin laminate produced in this way, the resin is applied to the metal plate as the rolling reduction increases. Although the adhesive strength decreases, the adhesive strength can be increased by heating to a temperature equal to or higher than the glass transition temperature of the resin after rolling, preferably to a temperature equal to or higher than the crystallization temperature of the resin.
次いで、これらの樹脂被覆極薄金属板、樹脂被覆極薄金属積層板、樹脂金属複合極薄板、樹脂金属複合極薄積層板に貫通孔を穿つ。穿孔は、パンチプレスや特許文献１に記載のロータリープレスを用いて行うことができる。貫通孔の大きさはは用途にもよるが、円孔の場合は径が１〜７ｍｍであることが好ましく、長方形などの多角形状の孔の場合は辺の最大長さが１〜７ｍｍであることが好ましい。樹脂被覆極薄金属積層板および樹脂金属複合極薄積層板においては、１回の穿孔操作で複数の金属板に穿孔することができる。 Next, through holes are formed in these resin-coated ultrathin metal plates, resin-coated ultrathin metal laminates, resin-metal composite ultrathin plates, and resin-metal composite ultrathin laminates. The perforation can be performed using a punch press or a rotary press described in Patent Document 1. The size of the through hole depends on the application, but in the case of a circular hole, the diameter is preferably 1 to 7 mm, and in the case of a polygonal hole such as a rectangle, the maximum side length is 1 to 7 mm. It is preferable. In the resin-coated ultrathin metal laminate and the resin metal composite ultrathin laminate, a plurality of metal plates can be perforated by a single perforation operation.
このようにして、樹脂被覆極薄金属板、樹脂被覆極薄金属積層板、樹脂金属複合極薄板、樹脂金属複合極薄積層板に貫通孔を穿孔した後、樹脂を除去することにより、本発明の貫通孔を有する極薄金属板が得られる。樹脂の除去は機械的に剥離してもよいし、機械的剥離が困難な場合は、鉱物油、植物油、動物油中で加熱することにより、剥離除去することができる。 In this way, the resin-coated ultra-thin metal plate, the resin-coated ultra-thin metal laminate plate, the resin-metal composite ultra-thin plate, the resin metal composite ultra-thin laminate plate, after the through-holes are drilled, the resin is removed, thereby An ultrathin metal plate having through-holes is obtained. The resin may be removed mechanically, or when mechanical peeling is difficult, the resin can be removed by heating in mineral oil, vegetable oil, or animal oil.
樹脂被覆極薄金属板や樹脂被覆極薄金属積層板は、金属板の表面に樹脂が被覆された状態で圧延加工および穿孔が行われ、これらの工程後まで金属板が樹脂で保護されるので、樹脂を除去した後に、金属板表面にスクラッチなどの微少疵のない貫通孔を有する極薄金属板が得られる。樹脂金属複合極薄板、樹脂金属複合極薄積層板では、最上層と最下層の金属板が圧延ロールや穿孔用の金型と接触するので、樹脂を除去した後の金属表面にスクラッチなどの微少疵のない極薄金属板が求められる場合は、これらの最上層と最下層の２枚以外の極薄金属板を用いればよい。 Resin-coated ultra-thin metal plates and resin-coated ultra-thin metal laminates are rolled and drilled with the resin coated on the surface of the metal plate, and the metal plate is protected with resin until after these steps. After the resin is removed, an ultrathin metal plate having through holes without scratches or the like on the surface of the metal plate is obtained. In resin-metal composite ultrathin plates and resin-metal composite ultrathin laminates, the uppermost and lowermost metal plates come into contact with the rolling rolls and the die for punching. When an ultrathin metal plate having no wrinkles is required, an ultrathin metal plate other than the uppermost layer and the lowermost layer may be used.
