また、これらの抗ウイルス性塩化ビニル系樹脂製組成物を成形して得られた抗ウイルス性塩化ビニル系樹脂製シートとすることができる。
さらに、ペースト用塩化ビニル系樹脂10~90重量部とサスペンジョン塩化ビニル系樹脂90~10重量部とを混合する工程と、
前記ペースト用塩化ビニル系樹脂と前記サスペンジョン塩化ビニル系樹脂とを含むポリ塩化ビニル系樹脂を溶融賦形する工程を備え、

さらに具体的には、10~90重量部のペースト用ポリ塩化ビニル系樹脂と、90~10重量部のサスペンジョンポリ塩化ビニル系樹脂とを含むポリ塩化ビニル系樹脂100重量部に対し、スルホン酸系界面活性剤0.5~10.0重量部と、可塑剤10~100重量部とを含有する抗ウイルス性ポリ塩化ビニル系樹脂組成物からなる表層を備える内装シートとすることである。
また、前記ポリ塩化ビニル系樹脂は、前記スルホン酸系界面活性剤が添加されている前記ペースト用ポリ塩化ビニル系樹脂と前記サスペンジョンポリ塩化ビニル系樹脂との混合物である内装シートとすることができる。
さらに、前記スルホン酸系界面活性剤が、前記ペースト用ポリ塩化ビニル系樹脂の製造段階で添加されている内装シートとしてもよい。
製造方法としては、ペースト用ポリ塩化ビニル系樹脂10~90重量部とサスペンジョンポリ塩化ビニル系樹脂90~10重量部とを含むポリ塩化ビニル系樹脂100重量部に対し、スルホン酸系界面活性剤0.5~10.0重量部と、可塑剤10~100重量部とを含有する抗ウイルス性ポリ塩化ビニル系樹脂組成物からなる内装シートの製造方法であって、前記スルホン酸系界面活性剤を含有する前記ペースト用ポリ塩化ビニル系樹脂と前記サスペンジョンポリ塩化ビニル系樹脂とを混合して前記ポリ塩化ビニル系樹脂を得る工程と、前記ポリ塩化ビニル系樹脂と前記可塑剤を混合して前記抗ウイルス性ポリ塩化ビニル系樹脂組成物を得る工程と、前記ウイルス性ポリ塩化ビニル系樹脂組成物を溶融賦形する工程を備える抗ウイルス性ポリ塩化ビニル系樹脂組成物からなる内装シートの製造方法。
前述の課題を解決するために本発明の第三の態様が用いた手段は、スルホン酸系界面活性剤を所定量含有するペースト用ポリ塩化ビニル系樹脂と可塑剤とを含むポリ塩化ビニル系ゾル組成物を塗工することを要旨とする。
具体的には、ペースト用ポリ塩化ビニル系樹脂100重量部に対し、スルホン酸系界面活性剤0.1~7.5重量部と可塑剤を含有し、スルホン酸系界面活性剤が、ペースト用ポリ塩化ビニル系樹脂の製造段階で添加された抗ウイルス性ポリ塩化ビニル系ゾル組成物を、基材表面に塗工してポリ塩化ビニル系樹脂製内装シートとすることである。
前述の課題を解決するために本発明の第四の態様が用いた手段は、少なくとも表層を備えた内装シートであって、表層がポリ塩化ビニル系樹脂100重量部に対し、スルホン酸系界面活性剤を0.1~10.0重量部と、可塑剤10~50重量部と、シリコーン系共重合体1~20重量部とを含有するポリ塩化ビニル系樹脂組成物からなることを特徴とする内装シートとすることである。
さらに、前記表層のポリ塩化ビニル系樹脂が前記ペースト用塩化ビニル系樹脂100~1重量部とサスペンジョン塩化ビニル系樹脂0~99重量部とを含むポリ塩化ビニル系内装シートとすることであり、前記ペースト用塩化ビニル系樹脂がスルホン酸系界面活性剤を含有し、また、前記表層を構成する樹脂組成物が充填剤1~50重量部を含有することである。
前記課題に対し、スルホン酸系界面活性剤の添加方法について鋭意検証した結果、スルホン酸系界面活性剤を予め添加したペースト加工用塩化ビニル樹脂を使用して壁紙を製造することで、美観を損ねることなく好適に抗ウイルス性壁紙を得られることを見出した。
具体的には、予めスルホン酸系界面活性剤を1.2重量%以上含有したペースト加工用塩化ビニル樹脂を樹脂成分として含む樹脂層と基材層とを備える抗ウイルス性壁紙とすることである。
本発明の第五の態様の抗ウイルス性壁紙は、ウイルスと接触後に短時間でウイルス力価を低減化してウイルスを不活化させ、外観にも優れる。
本発明の第一の態様の実施形態としては、10~90重量部のペースト用塩化ビニル系樹脂と、90~10重量部のサスペンジョン塩化ビニル系樹脂とを混合してなるポリ塩化ビニル系樹脂100重量部と、スルホン酸系界面活性剤0.5~10.0重量部とを含有することを特徴とする抗ウイルス性塩化ビニル系樹脂組成物である。
すなわち、スルホン酸系界面活性剤が微分散されることで、より効率よく抗ウイルス性を発揮することができる。そして、それによって成形加工時の初期着色を強くさせるスルホン酸系界面活性剤の添加量を低く抑えることができ、その結果さらに、成形加工時の変色を低減できるものと推定している。
したがって、ペースト用ポリ塩化ビニル系樹脂を用いる場合に、サスペンジョン塩化ビニル系樹脂とブレンドし固体状の樹脂組成物とすることで、上記のような溶融賦形法において抗ウイルス性塩化ビニル系樹脂製組成物を容易に成形加工することができる。
本発明で用いるスルホン酸系界面活性剤において、スルホン酸基は例えばインフルエンザウイルスのノイライミダーゼとの親和性が高く、阻害作用を現すことができる。また官能基の構造はノイライミダーゼへの接近に関して影響を示し、嵩高くなく立体障害を受け難い構造が肝要となる。その点において、アルキルベンゼンスルホン酸系界面活性剤は好適であり、特にドデシルベンゼンスルホン酸系界面活性剤が好ましい。
さらに、上記のスルホン酸系界面活性剤としては、スルホン酸塩系界面活性剤が好ましく、具体的にはナトリウム塩、カリウム塩などのアルカリ金属塩、カルシウム、バリウム等のアルカリ土類金属塩を好適に用いることができる。特にドデシルベンゼンスルホン酸ナトリウム(DBS)が好ましい。
また、複数のスルホン酸系界面活性剤を抗ウイルス性が阻害されない限りにおいて添加してもよく、その他の種類の界面活性剤を加えることも制限されない。
0.5~7.0重量部が好ましく、1.5~7.0重量部がより好ましく、1.5~4.2重量部がさらに好ましい。0.5重量部未満では抗ウイルス性塩化ビニル系樹脂製シートにした場合の抗ウイルス性に乏しく、10.0重量部を超える場合、加工が困難となる。
アクリル系高分子加工助剤を添加することで、ロール成形やカレンダー成形時のバンク内の回転流動や脱気が良好となり、プレートアウトが抑制されることから外観の良好なシートが得られる。
また多層構造である場合、積層される層には特に制限はない。例えば、抗ウイルス性塩化ビニル系樹脂組成物から成る層には、ポリ塩化ビニル系樹脂層や他の熱可塑性樹脂層、各種樹脂発泡層、印刷層や着色層などの意匠層、織布や不織布などの基材層などを、使用する用途や要求される物性に応じて積層することができる。
以下、本発明の第二の態様の実施形態について詳述する。
すなわち、スルホン酸系界面活性剤が微分散されることで、より効率よく抗ウイルス性を発揮することができる。そして、それによって成形加工時の着色を強くさせるスルホン酸系界面活性剤の添加量を低く抑えることができ、その結果さらに、成形加工時の変色を低減できるものと推定している。
したがって、ペースト用ポリ塩化ビニル系樹脂を用いる場合に、サスペンジョンポリ塩化ビニル系樹脂とブレンドし固体状の樹脂組成物とすることで、上記のような溶融賦形法において抗ウイルス性ポリ塩化ビニル系樹脂製組成物を容易に成形加工することができる。
0.5~5.0重量部が好ましく、0.8~4.4重量部がより好ましい。0.5重量部未満では抗ウイルス性ポリ塩化ビニル系樹脂製シートにした場合の抗ウイルス性に乏しく、10.0重量部を超える場合、加工が困難となる。
アクリル系高分子加工助剤を添加することで、ロール成形やカレンダー成形時のバンク内の回転流動や脱気が良好となり、プレートアウトが抑制されることから外観の良好なシートが得られる。
ここで、スルホン酸系界面活性剤はペースト用ポリ塩化ビニル系樹脂の製造段階で添加されていることが好ましい。この場合には、スルホン酸系界面活性剤を含有するペースト用ポリ塩化ビニル系樹脂とサスペンジョンポリ塩化ビニル系樹脂とを混合してポリ塩化ビニル系樹脂を得る工程と、ポリ塩化ビニル系樹脂と可塑剤を混合して抗ウイルス性ポリ塩化ビニル系樹脂組成物を得る工程と、ウイルス性ポリ塩化ビニル系樹脂組成物を溶融賦形する工程を有する製造方法によって製造することができる。
作業性やコストの面から、スルホン酸系界面活性剤を含有するペースト用ポリ塩化ビニル系樹脂とサスペンジョンポリ塩化ビニル系樹脂とを混合する工程で可塑剤や安定剤等を添加・混練して抗ウイルス性ポリ塩化ビニル系樹脂組成物を得る製造方法が好ましい。
本発明の第三の態様のポリ塩化ビニル系樹脂製内装シートは、基材層と抗ウイルス性ポリ塩化ビニル系樹脂層を有しており、抗ウイルス性ポリ塩化ビニル系樹脂層はポリ塩化ビニル系樹脂製内装シートにおいて表面側に設けられている。また抗ウイルス性ポリ塩化ビニル系樹脂層には、ペースト用ポリ塩化ビニル系樹脂と可塑剤とを含有している。
その添加方法であるが、一つは前述の重合工程においてスルホン酸系界面活性剤を乳化剤として添加する方法である。ただしこの場合には、添加されたスルホン酸系界面活性剤の影響により所望の性状のペースト用ポリ塩化ビニル系樹脂が得られない場合がある。
抗ウイルス性ポリ塩化ビニル系ゾル組成物はスルホン酸系界面活性剤を予め添加したペースト用ポリ塩化ビニル系樹脂と可塑剤等をミキサー等で攪拌して抗ウイルス性ポリ塩化ビニル系ゾル組成物を得る。
また、塗工後に抗ウイルス性ポリ塩化ビニル系ゾル組成物を乾燥固化する必要がある。乾燥固化する条件として、例えば、オーブン等を用いて180~220℃の温度で3~5分加熱する方法が挙げられる。
エンベロープを有するウイルスとしては、例えば鳥インフルエンザウイルス、人インフルエンザウイルス、豚インフルエンザウイルス等のインフルエンザウイルス、B型肝炎ウイルス、C型肝炎ウイルス、ヒト免疫不全ウイルス、水痘帯状疱疹ウイルス、単純ヘルペスウイルス、ヒトヘルペスウイルス、ムンプスウイルス、RSウイルス等が挙げられる。
以下、本発明の第四の態様について詳述する。
本発明の第四の態様の内装シートは、ポリ塩化ビニル系樹脂100重量部に対し、スルホン酸系界面活性剤を0.1~10.0重量部と、可塑剤10~50重量部と、シリコーン系共重合体1~20重量部とを含有するポリ塩化ビニル系樹脂組成物からなる表層を有する内装シートである。
内装シートに抗ウイルス性を付与する上でポリ塩化ビニル系樹脂100重量部に対してスルホン酸塩系界面活性剤を0.1~10.0重量部含有することが必要である。
そこで、まず、この点に関して以下に詳述する。
上記問題に関しては、スルホン酸系界面活性剤が予め添加されているペースト用塩化ビニル系樹脂を用いることで樹脂の着色を効果的に抑制することができる。
そこで、この点に関して以下に詳述する。
アクリル系高分子加工助剤を添加することで、ロール成形やカレンダー成形時のバンク内の回転流動や脱気が良好となり、プレートアウトが抑制されることから外観の良好なシートが得られる。
本発明の第五の態様の抗ウイルス性壁紙は、予めスルホン酸系界面活性剤を含むペースト用ポリ塩化ビニル樹脂、具体的にはペースト用ポリ塩化ビニル樹脂とスルホン酸系界面活性剤との合計に対し、スルホン酸系界面活性剤を1.2質量%以上含むペースト加工用塩化ビニル樹脂を樹脂成分として含む樹脂層と基材層とを備えることが肝要である。壁紙の製造工程において、ペースト加工用塩化ビニルと、可塑剤や充填剤、安定剤及び発泡剤等を混合してゾルを作製する過程があるが、スルホン酸系界面活性剤は可塑剤に不溶であるため、この過程で混合するとゾル中の分散性が悪く、製品にスジなどの外観不良を引き起こし美観を損ねる。
他方、スルホン酸系界面活性剤は水溶性である。また、乳化重合またはシード乳化重合でペースト加工用塩化ビニル樹脂を製造する際に、重合後の中間体的形態として水を溶媒とするラテックスが得られる。したがって、このラテックスにスルホン酸系界面活性剤を添加することで、スルホン酸系界面活性剤が塩化ビニル樹脂中へ良好に分散される。このように、スルホン酸系界面活性剤を重合後のラテックスに添加することで、重合条件に影響を与えることなく所望の性状を有するペーストポリ塩化ビニル樹脂が得られる。斯かる手法で得られた予めスルホン酸系界面活性剤を含有したペースト加工用塩化ビニル樹脂を用いることで、美観を損ねることなく壁紙を得ることができる。
表面強化壁紙性能規定とは、壁装問屋協議会および壁紙工業会により表面強化壁紙の品質や試験方法等について定めたものであり、具体的には引っ掻き試験後の傷つき性能を目視により判定するものである。性能は5等級で判定され、4級以上であると表面強化壁紙として認定される。

「ウイルス力価(1時間後)」と「ウイルス力価(試験前)」との差が抗ウイルス性の強弱を表しており、この差が大きいほど抗ウイルス性が強いことを示している。
日本壁装協会が定める表面強化壁紙性能規定(2004年制定、2009年改訂 3-2版)に準拠した試験で評価した。試験片は30mm×250mmの大きさのものを試験体より3試験片を採取して用いた。試験装置の本体はJIS L0849で規定する摩擦試験機II形を用い、摩擦子は表面強化壁紙性能規定で定める爪とホルダーを用いた。摩擦子の荷重は1.96N、爪の材質はSUS420‐J2、爪の先端部寸法は幅4.0mm×厚さ2.0mmであり、先端部の角のR寸法はスタート側がR0.10mm、リターン側がR0.15mmのものを使用した。試験片を摩擦子の往復方向と平行になるように試験機の試験片台に固定し、摩擦子を試験片の上に静置して移行距離120mmの間を毎分30回の往復速度で5回往復させたのち、試験片を試験片台より外して目視により試験片表面の傷つき程度を確認した。下記の等級と照合し、4級以上を表面強化性有りと判断する。
5級:一見視で特に変化が見られない
4級:多少表面傷が見られるが、比較的大きな表面層の破れ等は見られない
3級:表面層の破れが明確に見える
2級:表面が破けて紙等の裏打材が明らかに見える(長さ1cm未満)
1級:表面が破けて紙等の裏打材が明らかに見える(長さ1cm以上)

さらに、実施例505、506によるとトップコート層を付与することで表面強化性が4級以上になることも示されている。
また、パンデミック発生時の備えとして、備蓄用の防護衣、防護服、さらに、発熱外来用、感染症用、または飛沫感染用のテント等の内装シートとして使用することができる。
本発明の第二の態様によれば、接触したウイルスのウイルス力価を迅速に低減してウイルスを不活化させる外観の優れた内装シートを提供できる。
本発明の第三の態様によると、抗ウイルス性を有しつつ、汚れが付着しにくく、また付着しても簡単な清掃で汚れを落とすことができ、防汚処理等の定期的なメンテナンスを必要とせずに長期にわたって美観を維持することができる。
本発明の第四の態様によれば、接触したウイルスのウイルス力価を迅速に低減してウイルスを不活化させる外観の優れた内装シートを提供できる。
