Description
本発明における柔軟性を有するシートとしては、通常養生シートとして好適に用いられるものであれば特に限定されず、例えば、軟質の合成樹脂シートや合成樹脂製発泡シート、紙製のシート、天然繊維や合成繊維からなる織布や不織布などが挙げられる。
尚、本発明は下記実施例のみに限定されるものではない。
(実施例1)
重量平均分子量(Mw)3.3×105、融点135℃の高密度ポリエチレン(日本ポリケム社製ノバテック「HY540」)を同方向二軸混練押出機(プラスチック工学研究所社製)に供給して樹脂温度200℃で溶融混練した後、Tダイを用いてシート状に吐出し、吐出されたシート状の溶融混練物をロール温度110℃に制御したカレンダー成形機にて幅340mm、厚さ7.0mmのシートに成形してポリエチレン樹脂シートを得た。
延伸PE複合シート2を延伸方向と略同方向に幅16mmで細長く切断し、図2に示すように、延伸PE複合シート2,2の幅方向端部同士の隙間を約50mmとなるように配設したこと以外は実施例1と同様にして養生シート1を得た。
延伸PE複合シート2を貼り付けることなく、実施例1と同様のポリエチレン発泡シート3を養生シートとして用いた。
上記実施例及び比較例の養生シートについて、以下の評価を行った。評価結果は表1に示した。
(形状保持性)
上記養生シートを建築資材のコーナー部[角度90度、曲率(R)100mm]に沿わせて90度に折り曲げ5秒間保持した後、力を解放し以下の式で示す戻り角度を測定した。
(戻り角度)=(力解放後の折り曲げ角度)−90 ・・・式1
(施工テスト)
上記実施例及び比較例の養生シートを建築資材(鋼製150mm角材)の端部及び周囲を覆うように巻き付け形状保持性及び作業性を評価した。
2 熱可塑性樹脂シート
3 樹脂発泡シート
Claims (2)
- 柔軟性を有するシートの少なくとも片面に、圧延後延伸することにより全体の延伸倍率が10〜40倍に延伸され、厚さ0.05〜1.5mmであり、シートを折り曲げてシート形状を変化させた場合にその形状が実質的に保持される塑性変形性を有する熱可塑性樹脂シートが貼り付けられていることを特徴とする養生シート。
- 熱可塑性樹脂シートが、延伸オレフィン系樹脂シートからなることを特徴とする請求項1記載の養生シート。
