Description
本発明者らは、前記課題を解決するために鋭意検討した結果、ポリエチレンテレフタレート、ポリエチレンナフタレートまたはポリ乳酸からなるフィルム（A）、ナイロン６フィルム（B）、アルミニウム箔（C）、ポリプロピレンフィルム（D）がこの順に積層された積層材であって、Aが二軸延伸フィルムであり、BおよびDが無延伸フィルムであり、Ｃの厚さが８０〜２５０μｍであることを特徴とする積層材によって、従来よりも耐振動性、耐衝撃性に優れた二次電池用積層材が作成できることを見出し、本発明を完成するに至った。
The present inventors have made intensive studies in order to solve the above problems, a polyethylene terephthalate, of poly ethylene naphthalate or polylactic acid film (A), a nylon 6 film (B), aluminum foil (C), a polypropylene film (D) is a laminated material laminated in this order, A is a biaxially stretched film, B and D are unstretched films, and the thickness of C is 80 to 250 μm It has been found that a laminated material for a secondary battery having better vibration resistance and impact resistance than conventional materials can be produced by using the material, and the present invention has been completed.
本発明において、ポリエチレンテレフタレート、ポリエチレンナフタレートまたはポリ乳酸からなるフィルム（Ａ）（以下、単にＡと略すことがある。）とは、テレフタール酸とエチレングリコールを主成分としエステル結合によって重合されたポリエチレンテレフタレート、2,6-ナフタレンジカルボン酸とエチレングリコールを主成分としエステル結合によって重合されたポリエチレンナフタレートまたは、乳酸がエステル結合によって重合されたポリ乳酸が、二軸延伸により分子配向された高強度のポリエステルフィルムであり、公知のものが使用できる。
In the present invention, polyethylene terephthalate, of poly ethylene naphthalate or polylactic acid film (A) and (hereinafter, sometimes simply referred to as A.), Was polymerized by ester bonds as main components terephthalic acid and ethylene glycol polyethylene terephthalate, high 2,6-naphthalene dicarboxylic acid and ethylene glycol poly ethylene naphthalate, or polymerized by an ester bond as a main component, lactic polylactic acid which is polymerized by an ester bond, which is molecularly oriented by biaxial stretching It is a strong polyester film, and a known one can be used.
本発明において、ポリエチレンテレフタレート、ポリエチレンナフタレートまたはポリ乳酸からなる二軸延伸フィルム（Ａ）を用いないと、アルミニウム箔（Ｃ）を保護するナイロン６フィルム（Ｂ）が外部からの振動時の力によりすぐに磨り減って破れてしまい好ましくない。
In the present invention, polyethylene terephthalate, unless using poly ethylene naphthalate, or consisting of biaxially stretched polylactic acid film (A), a nylon 6 film for protecting aluminum foil (C) (B) is at vibration from the outside force It is unfavorable because it wears away quickly and tears.
ポリエチレンテレフタレート、ポリエチレンナフタレートまたはポリ乳酸からなるフィルム（Ａ）とナイロン６フィルム（Ｂ）とアルミニウム箔（Ｃ）とポリプロピレンフィルム（Ｄ）とはドライラミネート法によって接着することができる。具体的には、ＡとＢを接着しＡ／Ｂ積層材とし、このＢ側にＣを接着しＡ／Ｂ／Ｃ積層材とし、このＣ側とＤを積層させＡ／Ｂ／Ｃ／Ｄ積層材を得ることができる。あるいは、ＡとＢを接着しＡ／Ｂ積層材とし、別にＣとＤを積層しＣ／Ｄ積層材とし、Ａ／Ｂ積層材とＣ／Ｄ積層材とをＢとＣを重ね合わせ接着させ、Ａ／Ｂ／Ｃ／Ｄ積層材を製造できる。
Polyethylene terephthalate, can be bonded by dry lamination consists of poly ethylene naphthalate or polylactic acid film (A) and nylon 6 film (B) and aluminum foil (C) and a polypropylene film (D). Specifically, A and B are bonded to form an A / B laminated material, C is bonded to the B side to form an A / B / C laminated material, and the C side and D are laminated to form A / B / C / D. A laminated material can be obtained. Alternatively, A and B are bonded to form an A / B laminated material, and C and D are laminated separately to form a C / D laminated material, and A and B laminated material and C / D laminated material are laminated and bonded to B and C. A / B / C / D laminates can be manufactured.
また、二次電池容器は、本発明の積層材から積層材片を２枚切り出し、１枚の積層材を
ポリエチレンテレフタレート、ポリエチレンナフタレートまたはポリ乳酸からなるフィルム（Ａ）が外側になるように金型により絞り成形し、発電要素を封入するための絞り成型部を設けた成形材と、他の１枚の積層材とをポリプロピレン（Ｄ）側に重ね合わせ、ヒートシールにより融着して容器を作成することができる。
The secondary battery container, cut out two sheets of laminate material pieces from laminated material of the present invention, as one polyethylene terephthalate laminate, comprising poly ethylene naphthalate or polylactic acid film (A) is on the outside The container is formed by drawing with a mold and overlaying a molding material provided with a drawing part for enclosing a power generation element and another laminated material on the polypropylene (D) side and fusing by heat sealing. Can be created.
