Description
そこで、注目されるのがポリマー系材料中に無機系ナノ粒子を添加、分散させたナノ粒子添加ポリマー系材料である。これは、数%の添加で引張強さが30%以上向上するなど特性の大きな改善、改良が可能であり、難燃性の向上も報告されている(下記特許文献1、2および非特許文献1参照)。
本発明は、上記状況に鑑みて、脱ハロゲンで難燃性・耐摩耗性を有し、かつ機械的強度が高く、耐劣化特性が良好な鉄道車両用床材を提供することを目的とする。
〔1〕鉄道車両用床材において、ポリアミド、ポリイミド、ポリ乳酸、エポキシ樹脂、ポリエチレン又はポリプロピレンからなるポリマー系材料中に有機化処理したクレー系粒子を1.15重量%又は2.3重量%の分量で添加、分散させることにより、良好な難燃性・耐摩耗性、引張強さ・破断伸び、ならびに耐加熱老化性を全て備えるようにしたことを特徴とする。
本発明の鉄道車両用床材は、ポリマー系材料中に有機化処理したクレー(粘土)系粒子を少量添加・分散させたポリマー/有機化処理クレー系材料である。ポリマー系材料としてはポリアミド、ポリイミド、ポリ乳酸やエポキシ樹脂等の極性の強いポリマー系材料の他、ポリエチレン、ポリプロピレン等のオレフィン類のポリマー系材料でも変性、共重合、ポリマーブレンド等の前処理を行うことで使用が可能である。
なお、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づき種々の変形が可能であり、これらを本発明の範囲から排除するものではない。
