Description

【発明の詳細な説明】 本発明は、金属管もしくは鋼管と発泡付絶縁物とプラス
チック外被とから成る断熱・遮音パイプの製法に関する
。
このようなパイプの製法として、金属管の周りに軟質の
発泡付絶縁物を金属管の軸方向にのばしてくるむか、ま
たは螺旋状に巻付けて溶接し、続いて熱可塑性プラスチ
ック外被を付着させることが既に提案されている。
可塑剤の移行を防止するために、発泡材層を外被の間に
箔を入れ、この箔により内側の発泡付絶縁物を軸方向に
または螺旋状に完全に包囲している。
このようなパイプの製造においては、まず、箔に設ける
必要があるため製造の手間がかかり、又軟質の発泡材は
絶縁性が悪いという欠点があった。
この点に鑑み、本出願人は第１図に示すように、金属管
１に螺旋状保障体殊に紙製の螺旋状保障体２を装着し、
該螺旋状保障体に帯材３を縦添えしてスリット管に変形
し、スリットがまだ開いている間にこれに自己発泡性プ
ラスチックを注入装置４により封入し、続いて前記帯材
の縁部を溶接装置５により相互に結合させ、案内管６で
プラスチックを発泡させる形式の、金属管殊に鋼管と、
発泡付絶縁物と、外被とから成る断熱・遮音パイプの製
法を開発した。
しかしながら、本出願人は、発泡材層の硬化後、前記帯
材上に共重合体から成る被覆を押出塗布すると、押出塗
布された共重合体層が帯材に緊密に接着し、その結果、
完成パイプが曲げ易くなり、可撓性発泡材を使用した場
合、従来外被となっていた帯材が割れて、場合によって
はこの外被の破損を来たすような事態が起らなくなるこ
とを見出し、本発明を完成するに至った。
従って長大なパイプをドラムに巻くことができるように
なる。
本発明の実施例を第２図について説明する。
なお、第１図と同一部分は同一の参照番号を付す。
銅管１は、断熱・遮音の目的で、可撓性のポリウレタン
発泡材層７により包囲されている。
発泡過程の間、発泡材の型として働くのは帯材（もしく
は箔材）３′である。
これにはポリ塩化ビニル箔などが好適であるが、薄い金
属箔材を使用してもよい。
この帯材３１に、発泡材層７の硬化後、接着に好適なエ
チレンの共重合体または塩化ビニルをベースとする共重
合体から成る被覆８を押出塗布する。
なお、この押圧塗布の具体的方法については米国特許第
２２３５６８８号明細書に詳細に示されているため、省
略する。
この被覆８はその化学構造の故に帯材３′ときわめて緊
密に接着するので、パイプは容易に曲げることができ、
帯材３′が割れたりすることはない。
２は例えばポリウレタンから成る保障体で、帯材３′を
銅管１から等距離に保持している。
可撓性発泡材は耐光性がないので、帯材３′または共重
合体層８は、周知の方法例えば共重合体への顔料添加或
