Abstract
【解決手段】本発明の空気入りタイヤのインナーライナー熱可塑性樹脂60〜90重量%とエラストマー10〜40重量%を含むポリマー組成物の未延伸フィルムであって、酸素透過度が15×10−3ccm/m2・24hr・atm以下で、常温における破断伸度が200%以上である。タイヤの成形工程において、激しく変形させても破砕しないことからタイヤの製造が促進され、優れた空気浸透防止層としての空気浸透防止性を有する。
【選択図】なし
Description
ナイロン6とポリアミドエラストマーを重量比80:20で混合した樹脂組成物を260℃で溶融し、環状金型で押出し、クエンチ(急冷)することにより、厚さ50μmの未延伸ポリアミドシートを得た。
ナイロン6とポリアミドエラストマーの重量比を70:30にした以外は実施例1と同一の方法により行い、厚さ50μmの未延伸ポリアミドシートを得た。
比較例1は、エラストマーを含まずにナイロン6だけを利用して延伸させたフィルムの例を挙げたもので、ナイロン6を260℃で溶融して環状金型で押出し、クエンチすることで厚さ50μmの未延伸ポリアミドシートを得た。次に、未延伸ポリアミドシートは、ガラス転移温度と熱結晶化温度間の温度で2.7×2.7倍に延伸し、融点以下の温度でアニールして厚さ15μmの延伸ポリアミドフィルムを得た。
エラストマーを含まずにナイロン6だけを使用して製造した以外は実施例1と同一の方法により行い、厚さ50μmの未延伸ポリアミドシートを得た。
ナイロン6とポリアミドエラストマーの重量比を50:50にした以外は実施例1と同一の方法により行い、厚さ50μmの未延伸ポリアミドシートを得た。
ナイロン6を含まずにポリアミドエラストマーだけを使用して製造した以外は実施例1と同一の方法により行い、厚さ50μmの未延伸ポリアミドシートを得た。
ナイロン6を単独で使用する代わりにナイロン6とポリアミドエラストマーを重量比80:20で混合させて製造した以外は比較例1と同一の方法により行い、厚さ15μmの延伸ポリアミドシートを得た。
ナイロン6を単独で使用する代わりにナイロン6とポリアミドエラストマーを重量比70:30で混合させて製造した以外は、比較例1と同一な方法により行い、厚さ15μmの延伸ポリアミドフィルムを得た。
ナイロン6を単独で使用する代わりにナイロン6とポリアミドエラストマーを重量比50:50で混合させて製造した以外は、比較例1と同一な方法により行い、厚さ15μmの延伸ポリアミドフィルムを得た。
ナイロン6を単独で使用する代わりにポリアミドエラストマー単独で製造した以外は、比較例1と同一な方法により行い、厚さ15μmの延伸ポリアミドフィルムを得た。
