Description
1. 床材用化粧シートの基材シート側を被着材に貼着してなる床用化粧材であって、
前記床材用化粧シートが、ポリオレフィン系樹脂からなる基材シート上に、絵柄模様層、透明性接着剤層、透明性ポリプロピレン系樹脂層及び電離放射線硬化型樹脂からなる透明性表面保護層が順に形成されており、
前記透明性ポリプロピレン系樹脂層の厚みが150〜500μmであり、
前記透明性ポリプロピレン系樹脂層が、ホモポリプロピレンを、当該樹脂層を構成する樹脂の75重量%以上含み、
前記透明性ポリプロピレン系樹脂層の引張り弾性率が1000MPa以上であり、
前記床用化粧材は、バッカー層が形成されていないものである
ことを特徴とする床用化粧材。
2. 透明性ポリプロピレン系樹脂層が、ホモポリプロピレンのみから形成されている、上記項1に記載の床用化粧材。
3. 基材シートと絵柄模様層との間に、さらに着色隠蔽層が形成されている上記項1又は2に記載の床用化粧材。
4. 透明性表面保護層のおもて面に凹凸が形成されている上記項1〜3のいずれかに記載の床用化粧材。
以下、本発明の床用化粧材について説明する。
基材シートとしては、ポリオレフィン系樹脂からなるシートを用いる。通常は、ポリオレフィン系樹脂からなるフィルムを使用すればよい。
基材シートの上(被着材貼着面とは逆面、以下各層において同じ側を指す)には、絵柄模様層が形成されている。
基材シートと絵柄模様層との間には、必要に応じて、さらに着色隠蔽層を形成してもよい。着色隠蔽層は、化粧シートのおもて面から被着材の地色を隠蔽したい場合に設けられる。基材シートが透明性である場合は勿論、基材シートが隠蔽着色されている場合でも、隠蔽性を安定化するために形成してもよい。
絵柄模様層の上には、透明性接着剤層が形成されている。透明性接着剤層は、透明性のものであれば特に限定されず、無色透明、着色透明、半透明等のいずれも含む。この接着剤層は、絵柄模様層と透明性ポリエステル系樹脂層とを接着するために形成されている。
透明性接着剤層の上には、厚み150〜500μm、好ましくは300〜500μmの透明性ポリプロピレン系樹脂層が形成されている。
透明性ポリプロピレン系樹脂層の上には、電離放射線硬化型樹脂からなる透明性表面保護層が形成されている。電離放射線硬化型樹脂からなる表面保護層を形成することにより、化粧シートの耐摩性、耐衝撃性、耐汚染性、耐擦傷性、耐候性等を高めることができる。
本発明の床材用化粧シートを構成する層の少なくとも1種には、必要に応じて、耐候剤を配合してもよい。耐候剤としては、紫外線吸収剤、ヒンダードアミン系光安定剤等が好ましい。これらの耐候剤は、単独又は2種以上を混合して使用できる。
(紫外線吸収剤)
紫外線吸収剤としては、特に塩基性成分(特にヒドロキシル基)を有するものが好ましい。例えば、2−(2’−ヒドロキシ−3’,5’−ジ−tert−ブチルフェニル)−5−クロロベンゾトリアゾール、2−(2’−ヒドロキシ−3’−tert−ブチル−5’−メチルフェニル)−5−クロロベンゾトリアゾール、2−(2’−ヒドロキシ−3’−tert−アミル−5’−イソブチルフェニル)−5−クロロベンゾトリアゾール、2−(2’−ヒドロキシ−3’−イソブチル−5’−メチルフェニル)−5−クロロベンゾトリアゾール、2−(2’−ヒドロキシ−3’−イソブチル−5’−プロピルフェニル)−5−クロロベンゾトリアゾール等の、2’−ヒドロキシフェニル−5−クロロベンゾトリアゾール系紫外線吸収剤類、2−(2’−ヒドロキシ−3’,5’−ジ−tert−ブチルフェニル)ベンゾトリアゾール、2−(2’−ヒドロキシ−5’−メチルフェニル)ベンゾトリアゾール等の、2’−ヒドロキシフェニルベンゾトリアゾール系紫外線吸収剤類等の、ベンゾトリアゾール系紫外線吸収剤、2,2’−ジヒドロキシ−4−メトキシベンゾフェノン、2,2’−ジヒドロキシ−4,4’−ジメトキシベンゾフェノン、2,2’,4,4’−テトラヒドロキシベンゾフェノン等の、2,2’−ジヒドロキシベンゾフェノン系紫外線吸収剤類、2−ヒドロキシ−4−メトキシベンゾフェノン、2,4−ジヒドロキシベンゾフェノン等の、2ヒドロキシベンゾフェノン系紫外線吸収剤類、等のベンゾフェノン系紫外線吸収剤、サリチル酸フェニル、4−tert−ブチル−フェニル−サリシレート等のサリチル酸エステル系紫外線吸収剤が用いられる。その他に、ベンゾトリアゾール骨格にアクリロイル基又はメタクリロイル基を導入した反応性紫外線吸収剤等も用いられる。上記の中でも、特にベンゾトリアゾール系紫外線吸収剤が好ましい。なお、これら紫外線吸収剤の添加量は、樹脂分に対して、通常0.1〜5質量%程度である。
(ヒンダードアミン系光安定剤)
紫外線による各層の劣化をさらに防止し、耐候性を向上させるためには、他の耐候剤としてヒンダードアミン系光安定剤を添加することが好ましい。例えば、ビス−(2,2,6,6−テトラメチル−4−ピペリジニル)セバケート、ビス−(N−メチル−2,2,6,6−テトラメチル−4−ピペリジニル)セバケート、その他、例えば特公平4−82625号公報に開示されている化合物等が挙げられる。これらの光安定剤の添加量は特に限定されないが、通常、樹脂分に対して0.1〜5重量%程度である。
本発明の床材用化粧シートは、各種被着材と接合することにより、床用化粧材とできる。被着材の材質は特に限定されず、例えば、無機非金属系、金属系、木質系、プラスチック系等の材質が挙げられる。
(床材用化粧シートの作製)
両面にコロナ放電処理を施した60μm厚の着色ポリプロピレンフィルムを基材シート6として用意した。基材シート6の片面に、ウレタン−セルロース系樹脂(ウレタン及び硝化綿の混合物100重量部にヘキサメチレンジイソシアネート5重量部を添加してなる樹脂)溶液をグラビア印刷法により固形分量が2g/m2となるように塗工して裏面プライマー層7を形成した。
(床用化粧材の作製)
上記で得られた床材用化粧シート9の裏面プライマー層側を、約4μm厚の水溶性ウレタン変性エチレン・酢ビ系エマルジョン接着剤層10を介して12mm厚のラワン合板11に貼着し、ラミネート合板を作製した。
透明性ポリプロピレン系樹脂層の厚みを下記表1に示すように変えた以外は、実施例1と同様にして床用化粧材を作製した。
実施例1〜4及び比較例1で作製した床用化粧材に対して、耐衝撃試験を行った。具体的には、デュポン式及び落球式(JIS K5600−5−3準拠)の2種類の耐衝撃試験を行った。耐衝撃試験は、床用化粧材に形成されたV字形状の条溝を避けて、条溝部以外の部分で行った。結果を下記表2に示す。
バッカー層を有する従来品の床材用化粧材について、試験例1と同様にして、デュポン式及び落球式の2種類の耐衝撃試験を行った。
