Description
1.結合材、難燃剤、発泡剤、炭化剤及び充填剤を含有する被覆材であって、
上記結合材として、190℃におけるメルトマスフローレイトが0.1~300g/10minであり、且つ酢酸ビニル含有率が15~50質量%である酢酸ビニル-エチレン共重合樹脂を含むことを特徴とする被覆材。
2.更に、液状ハロゲン化合物を含有する、上記項1に記載の被覆材。
上記結合材として、190℃におけるメルトマスフローレイトが0.1~300g/10minであり、且つ酢酸ビニル含有率が15~50質量%である酢酸ビニル-エチレン共重合樹脂を含むことを特徴とする。以下、構成成分について説明する。
本発明で用いる結合材(バインダー成分)は、火災時に炭化し、炭化断熱層を形成する作用を有する。本発明で用いる結合材は、190℃におけるメルトマスフローレイト(以下、「MFR」という)が特定範囲であり、且つ特定の酢酸ビニル含有率を有する酢酸ビニル-エチレン共重合樹脂(以下、「本発明の酢酸ビニル-エチレン共重合樹脂」という)を必須成分として含む。
本発明で用いる難燃剤は、一般に火災時に脱水冷却効果、不燃性ガス発生効果、結合材炭化促進効果等の少なくとも1つの効果を発揮し、結合材の燃焼を抑制する作用を有するものである。
本発明で用いる発泡剤は、一般に火災時に不燃性ガスを発生させ、炭化していく結合材及び炭化剤を発泡させ、気孔を有する炭化断熱層を形成させる作用を有するものである。
本発明で用いる炭化剤は、一般に火災時に結合材の炭化とともにそれ自体も脱水炭化していくことにより、断熱性に優れた厚みのある炭化断熱層を形成する作用を有する。
本発明で用いる充填剤は、一般に炭化断熱層の強度を維持する作用を有する。
・無機粉体の脱水反応(結晶水・水和水の脱離)
・無機粉体の結晶構造の変化(多形転移)
・無機粉体の融解または分解反応
本発明の無機粉体を用いることにより、高温に晒された場合であっても、被覆材のずれ等の不具合を防止できる。その結果、安定して炭化断熱層を形成することができる。なお、上記「被覆材のずれ」は、炭化断熱層の形成前、形成中、形成後のいずれの場合に生じるものも含む。本発明では特に、被覆材が炭化断熱層を形成する前の被覆材のずれを効果的に防止することができる。
本発明の被覆材は、上記成分に加えて更に液状ハロゲン化合物を含むものが好適である。液状ハロゲン化合物は、被覆材の屈曲性、耐熱保護性等の向上に有効に作用する成分である。なお、上記の「液状」とは、常温(25℃)にて液体の性状を示すことを意味する。また、液状ハロゲン化合物には、リンを有するものは包含されない。
本発明の被覆材は、上記成分に加えて更に繊維物質を含むものが好適である。繊維物質が含まれることにより、多孔質炭化層の形状を保持する効果等が高まる。繊維物質の繊維長は、好ましくは1~30mm、より好ましくは2~20mmである。
本発明の被覆材は、通常、シート状成形体として使用することができる。シート状成形体の厚みは、適用部位等に応じて適宜設定すればよいが、好ましくは0.2~10mm、より好ましくは0.5~6mm程度である。
表1-1~1-3に示す配合に従い、各原料を120℃に加温したニーダーで混練、圧延後、室温まで放冷し、膜厚1.5mmのシート状の被覆材1~31を得た。なお、原料としては以下のものを使用した。
