Description
また、ラミネートシートを作製するのに際して、複数枚の樹脂シートを積重して積層体を形成させて熱ラミネーションによる接合を実施してシート接合体を形成させることが行われている。
この溶着によるシート接合体の作製方法においては、シート状部材どうしが二層に重なり合わされている積層体を二枚の樹脂シートで形成させ、この内の一方の樹脂シートの背面側から樹脂シートどうしが接する界面部に向けてレーザー光を照射して、この界面部で樹脂シートを溶融させて接合する方法などが知られている(例えば、特許文献1)。
一方で、レーザー光を用いる方法は、一つの溶着箇所と別の溶着箇所とで接合強度の差異を生じやすく、作製されるシート接合体の接合品質を向上させることが困難であるという問題を有している。
図1は、本実施形態に係るシート接合体作製方法を示す側面図である。
この図1にも示されているように、本実施形態においては、2枚のシート状部材1a、1bが水平方向に広がった状態で互いに重なり合う積層構造を有する積層体1を平板状の支持材2の上に形成させて、前記積層体1の上方に設けたレーザー照射装置4からレーザー光4aを照射して2枚のシート状部材1a、1bの界面部を加熱して溶着を実施する。
そして、支持材2は、5MPa加圧時の圧縮歪量が20μm以上400μm以下となる弾性を有していることがより好ましく、5MPa加圧時の圧縮歪量が30μm以上300μm以下となる弾性を有していることがさらに好ましい。
また、本実施形態において、支持材2の圧縮歪量の上限値が500μmとされているのは、5MPa加圧時の圧縮歪量が500μmを超える支持材を用いた場合、溶着時における熱膨張等といった第一シート状部材1aと第二シート状部材1bとの積層方向(厚み方向)に作用する応力に対して支持材が容易に変形してシート接合体に十分な接合強度が付与されないおそれを有するためである。
なかでも、シリコーンゴム組成物やポリエチレン、ポリプロピレンなどを含む樹脂組成物によって作製された支持材が好適である。
また、前記押さえ部材3には、照射されたレーザー光4aを透過させて積層体1に到達させるべく、積層体1の加圧に耐え得る十分な強度を有するとともにレーザー光4aの透過性能に優れたものが好適に用いられ、例えば、透明なガラス板のようなものが好適に用いられ得る。
なお、種々のレーザー光に対する透過性に優れ、高い強度を有している点においては、押さえ部材3として、円筒又は円柱状のガラスや、球状のガラスを用いる場合も同様である。
また、このようなガラス製の押さえ部材3を用いることなく、加圧気体によって第一シート状部材1aの上面(背面)を加圧する場合には、レーザー照射装置4から第一シート状部材1aに到達するレーザー光4aのエネルギー低下をよりいっそう抑制させ得る点において好適であるといえる。
より好ましくは、0.02〜0.25mm厚みの樹脂フィルムを用いることが望ましく、0.04〜0.10mm厚みの樹脂フィルムを用いることがさらに望ましい。
また、第一シート状部材1aを構成する樹脂フィルムが、上記のような厚みであることが好ましいのは、0.50mmよりも厚い樹脂フィルムは、一般的に剛性が高いことから厚みのバラツキなどが生じていた場合に、第二シート状部材1bとの界面に、背面側からの加圧作用を反映させることが難しくなって接合品質を低下させるおそれを有するためである。
この第二シート状部材1bとして用いられる樹脂シートも、第一シート状部材1aと同様に、0.01〜0.50mmのいずれかの厚みを有していることが好ましく、0.02〜0.25mm厚みであることがより好ましく、0.04〜0.10mm厚みであることがさらに好ましい。
また、レーザー光を集光させる手段も、特に限定されず、シリンドリカルレンズや回折光学素子(DOE)レンズを用いる従来公知の手段を採用することができる。
また、第一シート状部材1aとして用いる樹脂シートを透過する光透過率が30%以上となる波長のレーザー光を照射可能なレーザー照射装置を用いることが好ましく、50%以上の光透過率となる波長のレーザー光を照射可能なレーザー照射装置を用いることがより好ましく、70%以上の光透過率となるレーザー照射装置を用いることが特に好ましい。
そして、両シート状部材1a、1bの分解等を避け、溶着を促す目的で、瞬間的に高いエネルギーを投入するパルスレーザーよりも連続波のCWレーザーの方が好適に用いられ得る。
また、レーザー照射装置4の出力などについては、積層体1の界面部における光吸収性やシート状部材1a、1bの材質、厚み等によって適宜選択すればよい。
本実施形態においては、カーボンブラック、ポルフィリン系有機顔料、無機顔料、染料など、従来公知の光吸収剤を用いることができる。
例えば、第二シート状部材1bを構成する樹脂組成物に光吸収剤を配合しておく方法を、光吸収剤の塗布方法に代えて実施することも可能である。
このように予め第二シート状部材1bを構成する樹脂組成物に光吸収剤を配合しておくことで、光吸収剤の塗布作業などを省略することができ、溶着(接合)の工程を簡略化することができる。
前記土台G上に、前記支持材2を配し、第二シート状部材1bと第一シート状部材1aとを順に重ね合わせ、支持材2の上に二枚の樹脂シートによる積層体を形成させる。
このとき、予め、第一シート状部材1aと第二シート状部材1bとのいずれかに光吸収剤を塗布しておいて、この塗布面が内側となるように積層体を形成させる。
そして、この第一シート状部材1aと第二シート状部材1bとが積層された積層体1の上に、さらに、押さえ部材3を載置して、該押さえ部材3で積層体1を加圧する。
このとき、接合品質に優れたシート接合体を作製するためには、第一シート状部材1aに0.1kgf/cm2〜100kgf/cm2のいずれかの圧力が発生するように前記荷重Fの調整を行う必要がある。
第一シート状部材1aに加える圧力が上記のような範囲とされるのは、下限値未満の場合には、第一シート状部材1aと第二シート状部材1bとの密着性が不足して、溶着後の接合強度が不足するおそれがあり、上限値を超える場合には第一シート状部材1aと第二シート状部材1bとのいずれかを変形させてしまうおそれを有するためである。
このとき押さえ部材3にガラス板などを用いることによって、照射したレーザー光4aは、そのエネルギーが押さえ部材3に殆ど吸収されることなく積層体1の上面(第一シート状部材1aの背面)に到達する。
そして、第一シート状部材1aの背面側から、第二シート状部材1bとの界面側へと第一シート状部材1aを通過したレーザー光4aは、この界面部に配された光吸収剤にその光が吸収され、熱エネルギーに変換される。
このときの発熱によって、第一シート状部材1a(又は、第二シート状部材1b)の内面側が溶融して、溶融樹脂が第一シート状部材1aと第二シート状部材1bとの界面に充満され第一シート状部材1aと第二シート状部材1bとが溶着されることとなる。
そして、このレーザー光4aのスポット位置を、走査させるなどしてレーザー光4aが照射される領域を広げ、第一シート状部材1aと第二シート状部材1bとの間に広範囲な溶着箇所を形成させる。
しかも、第二シート状部材1bが、所定の弾性を有する支持材2によって背面側から支持されており、第一シート状部材1aが所定の圧力で加圧されていることから、この溶着コンディションが溶着領域全般において略均質な状態となる。
また、別の箇所において溶着を実施した場合にも、先の溶着箇所と同等の溶着状態で第一シート状部材1aと第二シート状部材1bとを接合させることができる。
すなわち、接合品質に優れたシート接合体が形成されることとなる。
この図2に例示のシート接合体の製造方法では、第一シート状部材1aが長尺帯状でロール状に巻回されたものがシート接合体の作製に供される。
また、同様に第二シート状部材1bも長尺帯状のものがロール巻きされた状態でシート接合体の作製に供される。
また、このシート接合体作製方法においては、前記支持材2として、例えば、無端状のシリコーンゴム平ベルトなどが用いられ、該支持材2は、図1における土台Gに相当するテーブル6の上面に摺接されるようにローラ7に巻きかけられて用いられる。
また、図2に例示のシート接合体の製造方法では、中空円筒状のガラス製押さえ部材3が用いられ、該押さえ部材3は、前記シリコーンゴム平ベルトの移動方向にあわせて外周面を移動させ得るように回転自在な状態で前記テーブル6の上方に配されている。
そして、図2に例示のシート接合体の製造方法では、円筒状の押さえ部材3の中空領域に配されているレーザー照射装置4からシリコーンゴム平ベルト側に向けてレーザー光4aを照射し、この押さえ部材3とシリコーンゴム平ベルトとの間を通過する第一シート状部材1aと第二シート状部材1bとの溶着を実施する。
そして、この押さえ部材3を、第二シート状部材1bと第一シート状部材1aとの積層体の上面に当接させつつ、積層体の送り出される方向にしたがって回転させるとともに、前記支持材2を積層体の下面に当接させつつ積層体の送り出される方向に移動させる。
このとき押さえ部材3に下向き荷重を加えることによって、第一シート状部材1aを第二シート状部材1b側に加圧しつつレーザー光4aを照射して溶着を実施させ、得られたシート接合体5をロール状に巻き取ることによって連続的な生産を実施する。
支持材(1mm厚みのシリコーンゴムシート、5MPa加圧時の圧縮歪量が356.0μm)の上に、二枚のポリエチレンテレフタレート(PET)フィルム(50μm厚みの、大きさ1000mm×50mm)を積層し、上面側からガラス板で5kgf/cm2の圧力で加圧を行い、この加圧に用いているガラス板を通してレーザー光(波長940nm、出力20W、スポット径2mmφ)を照射し、ビームスポットを100mm/sの速度で走査させて長さ1000mmにわたる線状の溶着を実施しシート接合体を作製した。
なお、一方のPETフィルムには、表面に光吸収剤(ジェンテックス社製「Clearweld、LD120C」)を塗布した状態で溶着を実施した。
この1000mmにわたる線状の溶着区間を、溶着開始点から終了点まで200mm長さごとに5つに区分し、それぞれの区分におけるせん断強度を測定したところ、得られたせん断強度の値は、60±5N/cm2の範囲に収まっており接合品質が良好であることが確認できた。
支持材を5MPa加圧時の圧縮歪量が20.1μmのアラミド系不織布(300μm厚み)に代えた以外は、実施例1と同様にシート接合体を作製した。
その結果、得られたシート接合体におけるそれぞれの区間のせん断強度は60±5N/cm2の範囲に収まっており接合品質が良好であることが確認できた。
支持材を5MPa加圧時の圧縮歪量が4μmのステンレス材に代えた以外は、実施例2と同様にシート接合体を作製した。
その結果、得られたシート接合体におけるそれぞれの区間のせん断強度は20〜60N/cm2の範囲となっており、実施例1、2に比べると接合強度のバラツキが大きい結果となった。
