<難燃性二軸配向ポリエステルフィルム>
本発明の難燃性二軸配向ポリエステルフィルムは、ポリマー成分として、ポリエチレンテレフタレートもしくはポリエチレンナフタレートをポリエステルフィルム重量を基準として70重量%以上99.5重量%以下の範囲で含有し、また下記式(1)もしくは下記式(2)で表される平均粒子径0.5~3.0μmの難燃剤粒子を0.5重量%以上30重量%以下の範囲で含有し、
かつ該ポリエステルフィルム中に含まれる最大長10μm以上の粗大粒子の個数は10個/m2以下である。
本発明の難燃性二軸配向ポリエステルフィルムは、ポリマー成分としてポリエチレンテレフタレートもしくはポリエチレンナフタレートを用いる。該ポリマー成分の含有量は、ポリエステルフィルム重量を基準として70重量%以上99.5重量%以下の範囲である。これらポリマー成分の含有量の下限値は75重量%であることが好ましく、78重量%であることがより好ましく、80重量%であることがさらに好ましく、85重量%であることが特に好ましい。
これらポリマー成分の含有量が下限値に満たないとフィルムの機械強度が低下する。一方、これらポリマー成分の含有量が上限値を超えると相対的に難燃成分の含有量が少なく、十分な難燃性が発現しない。
これらの共重合成分は、モノマー成分として配合され、共重合化されたものでもよく、また他のポリエステルとのエステル交換反応により共重合化されたものでもよい。
本発明は、難燃成分として下記式(1)で表されるホスフィン酸塩もしくは下記式(2
)で表されるジホスフィン酸塩を難燃剤粒子として用いる。以下、これらを総称してホスフィン酸塩類と称することがある。
かかるホスフィン酸塩はホスフィン酸金属塩とも称される化合物であり、R1、R2として、水素、メチル基、エチル基、n-プロピル基、イソプロピル基、n-ブチル基、t-ブチル基、ペンチル基、ヘキシル基、フェニル基、が例示される。またMとしてアルミニウム、マグネシウム、カルシウムが例示され、価数mは2~4の整数である。
これらのホスフィン酸塩類の中でも、ジエチルホスフィン酸アルミニウムが特に好ましい。
本発明におけるリン原子濃度は、ポリエステルフィルムの重量を基準として0.1重量%以上7重量%以下であることが好ましい。またかかるリン原子濃度の下限値は、より好ましくは1.0重量%、さらに好ましくは2.0重量%、特に好ましくは2.5重量%である。一方かかるリン原子濃度の上限値は、より好ましくは6.0重量%、さらに好ましくは5.0重量%である。
本発明の難燃性二軸配向ポリステルフィルムには、フィルムの取り扱い性を向上させるため、発明の効果を損なわない範囲で不活性粒子などが添加されていても良い。かかる不活性粒子としては、例えば、周期律表第IIA、第IIB、第IVA、第IVBの元素を含有する無機粒子(例えばカオリン、アルミナ、酸化チタン、炭酸カルシウム、二酸化ケイ素など)、架橋シリコーン樹脂、架橋ポリスチレン、架橋アクリル樹脂粒子等の耐熱性の高いポリマーよりなる粒子が挙げられる。
本発明におけるポリエステルフィルムの厚みは、2μm以上200μm以下であることが好ましい。従来は、ポリエステルフィルムにリン系難燃剤を添加する方法で難燃化させようとすると、ポリエステルフィルムの機械的特性や耐加水分解性の低下を引き起こすため、ポリエステルフィルムそのものをリン系難燃剤で難燃化するのではなく、難燃剤を含む他の層をポリエステルフィルムに積層させる手法がとられていたのに対し、本発明はかかる厚みを有するポリエステルフィルムそのものにリン系難燃剤を添加できる特徴を有するものである。
本発明の難燃性二軸配向ポリエステルフィルムの表面粗さRa(中心線平均粗さ)は0.1μm以上2μm未満であることが好ましい。表面粗さRaの上限はより好ましくは1.5μm未満、さらに好ましくは1.0μm未満、特に好ましくは0.5μm未満である。また表面粗さRaの下限は0.2μm以上であってもよく、さらに0.3μm以上であってもよい。より好ましい表面粗さRaの範囲として、0.1μm以上1.5μm未満、さらに好ましくは0.1μm以上1.0μm未満、特に好ましくは0.1μm以上0.5μm未満である。また本発明の難燃成分の含有量が多い領域においては、0.2μm以上1.5μm未満、0.3μm以上1.0μm未満、あるいは0.3μm以上0.5μm未満であってもよい。
本発明の難燃性二軸配向ポリエステルフィルムの機械強度は150MPa以上であることが好ましく、より好ましくは160MPa以上、さらに好ましくは170MPa以上、特に好ましくは180MPa以上である。かかるフィルム機械強度は、ポリエステルフィルムに配合する難燃剤粒子の平均粒子径を上述の範囲内とし、かつ最大長10μm以上の粗大粒子を10個/m2以下に低減することにより得られる。
本発明の難燃性二軸配向ポリエステルフィルムは、121℃、2気圧の飽和水蒸気中で10時間処理した後のポリエステルフィルム引張強度保持率が80%以上であることが好ましい。かかるフィルム引張強度保持率は、さらに好ましくは85%以上である。かかる引張強度保持率はポリエステルフィルムのフィルム連続製膜方向(以下、長手方向、縦方向、MD方向と称することがある)またはその直交方向(以下、幅方向、横方向、TD方向と称することがある)の少なくとも一方向における引張強度保持率を指し、両方向とも満たすことがさらに好ましい。
本発明の難燃性二軸配向ポリエステルフィルムの製造は、公知の製膜方法を用いて製造することができ、例えばホスフィン酸塩を含むポリエステルを十分に乾燥させた後、融点~(融点+70)℃の温度で押出機内で溶融し、Tダイを通じて溶融押出し、フィルム状溶融物を冷却ロール(キャスティングドラム)上で急冷して未延伸フィルムとし、次いで該未延伸フィルムを逐次または同時二軸延伸し、熱固定する方法で製造することができる。逐次二軸延伸により製膜する場合、未延伸フィルムを縦方向に60~170℃で2.3~5.5倍、より好ましくは2.5~5.0倍の範囲で延伸し、次いでステンターにて横方向に80~170℃で2.3~5.0倍、より好ましくは2.5~4.8倍の範囲で延伸する。
本発明の難燃性二軸配向ポリエステルフィルムは、金属層と積層された難燃性ポリエステルフィルム積層体として用いることができる。ここで金属層には、フィルム上に層状に形成された形状のもの、導線などの形状のもの、回路など一定のパターン形状のものなどが含まれる。
本発明の難燃性二軸配向ポリエステルフィルムおよびその積層体はフレキシブルプリント回路基板に用いることができる。
