前記管状体(a)と前記管状体(b)とを互いに挿入して接合する工程と、
該接合部にレーザー光を照射して接着させる工程とを含み、
前記管状体(a)の貯蔵弾性率が1.0×107〜6.7×108Paであり、前記管状体(b)の貯蔵弾性率が2×107〜9×108Paであり、かつ管状体(a)よりも管状体(b)の貯蔵弾性率が高い事を特徴とする管状物の製造方法である。
前記熱可塑性樹脂組成物(A)に使用されるスチレン系エラストマーとしては、芳香族ビニル重合体ブロック(I)と共役ジエン系重合体ブロックまたその水添ブロック(II)とからなるブロック共重合体であることが好ましい。
(式中、u1:内周における半径方向の変位(m)、p1:内周に働く圧力(Pa)、r1:内周の半径(m)、r2:外周の半径(m)、m:ポアソン数(ポアソン比の逆数)、E:縦弾性係数(Pa)である。)
式(1)に示すように、半径方向変位u1は縦弾性係数Eと反比例するため、E値が大きくなると、u1が小さくなる。半径方向変位u1が小さければ、2本の管状体を挿入する場合に大きな挿入力が必要となることを意味する。そこで本発明では、管状体の細管の外径と太管の内径との比(細管外径/太管内径=X)を、所定範囲に限定すると共に、前記管状体(a)と前記管状体(b)の貯蔵弾性率も所定範囲に限定した。なお、Xが所定範囲を超えると大きな挿入力が必要となることも、上式(1)から理解できる。
ポリオレフィンを含む熱可塑性樹脂組成物(B)に使用されるポリオレフィン系樹脂は、上記した管状体(a)に使用するものと同じものを使用することができる。この際、管状体(a)と管状体(b)とに配合するポリオレフィン系樹脂は、同じであっても異なっていてもよい。
管状体(a)と管状体(b)との接合方法に限定はない。したがって、例えば、垂直な端部を有する細管に、端部を斜めにカットした太管を挿入したり、管状体の接合時に物理的に細管を短時間拡張し、太管を挿入した後にもとの内径に戻す方法などが採用できる。
本発明では、管状体(a)と管状体(b)との接合部において、前記管状体(a)および/または前記管状体(b)に、吸収波長700〜2,500nmの吸収剤が介在することが必要である。この際、「接合部」とは、管状体(a)と管状体(b)との接触面に限られず、細管の内側、太管の外側に吸収剤を介在させ、または管状体(a)が積層構造体である場合には、積層体のいずれかの層に吸収剤を含ませていてもよい。同様に、単層の場合であっても、接合部に吸収剤を含ませてもよい。このような吸収剤の介在場所を図6に例示する。従って、本発明における「介在させる工程」とは、積層体の接着部となる層に吸収剤などの染料を含ませることや、接着部の表面に吸収剤を何らかの方法で塗布することなどをいう。
本発明のレーザー接着に用いるレーザーは、一般的な半導体レーザー(波長:800〜960nm)及びYAGレーザー(波長:1096nm)などの透明樹脂を透過しやすい近赤外線レーザーを用いることが望ましい。それ以上の高い波長域になると熱可塑性樹脂組成物(A)やポリオレフィン系樹脂がレーザーを吸収し、接着が困難となる場合がある。特に半導体レーザーは比較的安価であり、熱変換効率も他の波長のレーザーに比べて高いといった利点があり、消費電力の低下が図れるため好ましい。なお、レーザー接着によれば、接着部からの接着剤の溶出を回避でき、得られる管状体の安全性を向上させることができる。
本発明の管状物は、上記管状体(a)と管状体(b)とをレーザー溶着したものであり、用途に応じて至適な管状体を使用することで、各種の中空成形品とすることができる。これらの用途は、例えば、玩具、日用品、食品容器、雑貨、弱電部品、医療用品、自動車部品、工業部品などを挙げることができる。その中でも、透明性が要求される管状物であって、かつ高い接合部の気密性が要求される食品や医療用品、その他、流体の輸送に関し、内容物の観察が必要な用途に好適に用いられる。さらに食品や医療用品の製造において本発明の方法を用いると、管状体からの接着剤などの溶出物を回避できるので安全性の面で好ましい。
