すなわち、本発明の課題は、酸成分の主成分がテレフタル酸であり、ジオール成分の主成分がエチレングリコールである結晶性ポリエステル(a)と、酸成分の主成分がテレフタル酸であり、ジオール成分中にエチレングリコール以外の共重合成分を含有する非晶性ポリエステル(b)とを主成分とする樹脂組成物(A)で構成され、JIS-K7121に準じて示差熱走査型熱量計(DSC)で測定される再昇温過程における融解エンタルピーΔHmの値が15J/g以上35J/g以下であるポリエステル系熱収縮性チューブ(以下「本発明のチューブ」ともいう。)により達成される。
本発明のチューブで用いられる樹脂組成物(A)は、酸成分の主成分がテレフタル酸であり、ジオール成分の主成分がエチレングリコールである結晶性ポリエステル(a)と、酸成分の主成分がテレフタル酸であり、ジオール成分がエチレングリコール以外の共重合成分を含有する非晶性ポリエステル(b)とを主成分として含む。
本発明において、結晶性ポリエステルとは、JIS-K7121に準じて、DSCを用いて-50℃から300℃まで加熱速度10℃/分で昇温し、300℃で1分間保持した後、-50℃まで冷却速度10℃/分で降温を行い、-50℃で1分間保持した後、再度300℃まで加熱速度10℃/分で昇温した際、2度目の昇温時に明確な融解ピークが現れるポリエステル系樹脂を指す。結晶性ポリエステル(a)の共重合成分のうち、酸成分はテレフタル酸を主成分とし、ジオール成分はエチレングリコールを主成分とする。主成分であるテレフタル酸とエチレングリコールは、酸成分またはジオール成分中にそれぞれ51mol%以上、好ましくは70mol%以上、さらに好ましくは80mol%以上の割合で含まれる。また、結晶性ポリエステル(a)は、酸成分またはジオール成分中に49mol%以下、好ましくは30mol%以下、さらに好ましくは20mol%以下の範囲であればその他の共重合成分を含んでいても構わない。
、テトラブロモビスフェノールA、テトラブロモビスフェノールA-ビス(2-ヒドロキシエチルエーテル)等から誘導されるジオール成分が挙げられる。なかでもジエチレングリコール、1,3-プロパンジオールなどが好ましい。
本発明において、非晶性ポリエステルとは、JIS-K7121に準じて、DSCを用いて-50℃から300℃まで加熱速度10℃/分で昇温し、300℃で1分間保持した後、-50℃まで冷却速度10℃/分で降温を行い、-50℃で1分間保持した後、再度300℃まで加熱速度10℃/分で昇温した際、2度目の昇温時に明確な融解ピークが現れないポリエステル系樹脂を指す。非晶性ポリエステル(b)の酸成分はテレフタル酸を主成分とし、ジオール成分はエチレングリコールを主成分とし、エチレングリコール以外の共重合成分を1mol%以上、好ましくは15mol%以上、さらに好ましくは25mol%以上であり、49mol%以下、好ましくは45mol%以下の範囲で含有する。
本発明のチューブは、樹脂組成物(A)中に、酸成分の主成分がテレフタル酸であり、ジオール成分の主成分が1,4-ブタンジオールである結晶性ポリエステル(c)をさらに含むことができる。樹脂組成物(A)中に結晶性ポリエステル(c)を含有させることにより、樹脂組成物(A)のガラス転移温度Tgや結晶化速度を調整することができる。このような効果を得るためには、結晶性ポリエステル(c)の含有率を樹脂組成物(A)100質量%に対して20質量%以下、好ましくは15質量%以下、さらに好ましくは10質量%以下とすることが望ましい。
本発明のチューブは、JIS-K7121に準じて、DSCで測定される再昇温過程における融解エンタルピーΔHmの値が15J/g以上、好ましくは18J/g以上、さらに好ましくは20J/g以上であり、35J/g以下である。本発明のチューブは、融解エンタルピーΔHmの値が上記範囲にあることにより耐熱性を発現でき、これによりコンデンサや電池の被覆材として好適に利用できる。融解エンタルピーΔHmの値が35J/gを超えると、コンデンサ等の実装工程等の高温下に曝された場合、一度コンデンサ等の被覆物に密着したチューブが結晶の成長により弛緩してしまうなどの問題点が生じやすくなる。また15J/g未満であると、耐熱性や耐薬品性など結晶性樹脂の特徴が損なわれる場合がある。
なお、共重合成分である酸成分およびジオール成分の種類と含有量は、周知の方法、例えば、核磁気共鳴(NMR)測定装置、その他の機器分析装置で定性定量分析することができる。
本発明のチューブの製造方法は、通常のチューブラ法により製膜することができ、上記記載のポリエステル原料を溶融後チューブ状に環状ダイで円筒状に押出して成形加工することにより達成される。本発明のチューブは、未延伸チューブをその径方向に1.2倍以上、好ましくは1.3倍以上、より好ましくは1.4倍以上から3.0倍以下、好ましくは2.5倍以下、より好ましくは2.0倍以下の範囲、かつ、その長さ方向に1.0倍以上、好ましくは1.02倍以上から2.0倍以下、好ましくは1.5倍以下、より好ましくは1.3倍以下の範囲の倍率で延伸させて得られたものが好ましい。ここで、チューブの径方向の延伸倍率が1.2倍以上であれば被覆するのに足りる収縮量が得られ、また3.0倍以下であれば、厚み振れが大きくなる傾向を抑えることができるとともに、配向結晶化による収縮率の低下を抑えることができる。一方、チューブの長さ方向の延伸倍率が2.0倍以下であれば、長さ方向の収縮量が大きくなりすぎて、電子部品等を被覆加工したときに被覆位置がずれる現象や、カット長さを長くする必要もないためコストアップを抑えることができる。
本発明のチューブは、上記樹脂組成物からなり、特定の熱収縮を有するものが特にコンデンサや電池の被覆材としての性能が優れているものであり、
(1)100℃の温水中に10秒間浸漬したときの長さ方向の収縮率が2%以上、好ましくは3%以上、さらに好ましくは5%以上であり、20%以下、好ましくは15%以下、さらに好ましくは12%以下の範囲である。また、径方向の収縮率は、15%以上、好ましくは20%以上、さらに好ましくは25%以上であり、60%以下、好ましくは50%以下、さらに好ましくは45%以下である。
さらに好ましくは(1)と同様に次の特性を満足するものが好ましい。
(2)80℃の温水中に10秒間浸漬したときの長さ方向の収縮率が2%以上、好ましくは3%以上、さらに好ましくは5%以上であり、15%以下、好ましくは12%以下、さらに好ましくは10%以下の範囲である。また、径方向の収縮率は、10%以上、好ましくは15%以上、さらに好ましくは20%以上であり、60%以下、好ましくは50%以下、さらに好ましくは45%以下である。
(1)ここで、洗浄膨れ試験は、コンデンサ製造工程における熱収縮性チューブの膨張を評価する試験方法である。具体的には、300℃のニクロム線ヒーターにて3.6秒間で被覆した後、常温水に15分間、60℃温水に30分間、さらに常温水に15分間連続して浸漬し、熱風循環式オーブン中95℃雰囲気下で60分間曝した後に、被覆した熱収縮性チューブ(以下、「被覆チューブ」ともいう。)の外観を目視により評価する。洗浄膨れ試験後の熱収縮性チューブの膨張の発生原因は、2回の常温水と60℃温水中に浸漬した際に被覆チューブとコンデンサとの隙間に水が浸入し、その後、熱風循環式オーブン中95℃雰囲気下に曝された際に、その隙間に侵入した水が蒸発して体積が増加するため、被覆チューブとコンデンサの隙間の圧力が上昇し、被覆チューブの膨張が生じると推測される。
(2)フラックス膨れ試験は、基板実装時のチューブの膨張を評価する試験方法である。具体的には300℃のニクロム線ヒーターにて3.6秒間で被覆し、熱風循環式オーブンにて85℃雰囲気下60分熱処理を行った後に、コンデンサの封口部にフラックス(例えば、株式会社 弘輝 JS-E-11)を塗布し、基板とコンデンサ封口部分が密着するように基板に装着したものを、再び熱風循環式オーブン中、160℃雰囲気下に2分間さらした後の被覆チューブ外観を目視により評価する。フラックス膨れ試験後のチューブの膨張の発生原因は、コンデンサの封口部に塗布したフラックスが、被覆チューブとコンデンサの隙間に浸入し、その後の熱風循環式オーブン中160℃雰囲気下に曝された際に、被覆チューブとコンデンサの間に浸入したフラックスが蒸発し体積が増加するため、被覆チューブとコンデンサの隙間の圧力が上昇し、被覆チューブの膨張が生じると推測される。
(3)高温放置試験は、耐熱性を評価する試験方法であり、300℃のニクロム線ヒーターにて3.6秒間で被覆し、熱風循環式オーブンにて85℃雰囲気下60分のエージングをかけた後、再び熱風循環式オーブン中、150℃雰囲気下に60分さらした後の被覆チューブ外観を目視により評価する。高温放置試験後のチューブの膨張の発生原因は、従来のポリエチレンテレフタレート樹脂製の熱収縮性チューブでは、熱風循環式オーブン中150℃雰囲気下に曝された際に、結晶化が進行し結晶自体の膨張と結晶間の干渉が多く発生するためチューブの体積が増加し、被覆チューブの膨張が発生すると推測される。
本発明のチューブは、アルミ電解コンデンサなどのコンデンサの被覆用として好適に用いることができるが、他の用途、例えば、電線(丸線、角線)、乾電池、リチウムイオン電池等の2次電池、鋼管又はモーターコイルエンド、トランスなどの電気機器や小型モーター、あるいは電球、蛍光灯、ファクシミリやイメージスキャナーの蛍光灯被覆用チューブとしても利用可能である。
なお、本明細書中に表示される熱収縮性チューブについての種々の測定値及び評価は次のようにして行った。
融解エンタルピーΔHmは、JIS-K7121に準じて、パーキンエルマー社製DSC-7を用いて、製膜された熱収縮性チューブから切り出した試料10mgをJIS-K7121に準じて、加熱速度を10℃/分で-50℃から300℃まで昇温し、300℃で1分間保持した後、冷却速度10℃/分で-50℃まで降温し、-50℃で1分間保持した後、再度加熱速度10℃/分で300℃まで昇温した時のサーモグラムから求めた。
ガラス転移温度Tgについても、JIS-K7121に準じて、ΔHm同様に求めた。
100℃又は80℃の温水中に10秒間浸漬した前後の熱収縮性チューブの長さ及び折径を測定して、算出した。
長さ方向収縮率[%]=[(浸漬前のチューブの長さ-浸漬後のチューブの長さ)/浸漬前のチューブの長さ]×100
径方向収縮率[%]=[(浸漬前のチューブの折径-浸漬後のチューブの折径)/浸漬前のチューブの折径]×100
