Abstract
Description
特許文献1には、この欠点を改良する為に紫外線硬化樹脂などで表面をコーティングする方法や、ポリカーボネート樹脂とアクリル系樹脂を共押出した基板にハードコートを施す方法が提案されている。
しかし、ポリカーボネート樹脂の表面にハードコートを施しただけでは要求される鉛筆硬度を満たす事ができず表面硬度を要求する用途には使用できない。
また、アクリル系樹脂を表層に施す方法では、表面硬度がある程度向上するので、情報表示機器前面板などに用途が広がるが、この方法によれば、異なる材料の2層構成のアクリル系樹脂とポリカーボネート樹脂との吸水特性や、ガラス転移温度に代表される耐熱性の違いにより大きな反りを生じることがあるので環境変化が生じる用途では不具合が発生する。
特許文献2には、反りを抑える方法として吸水率の低い樹脂をポリカーボネート樹脂上に積層する積層体が開示されているが、環境試験の40℃/90%は高温高湿の条件としては不十分であり、低反り性の要求性能を十分評価しているとは言えない。また本文献で扱われているMS樹脂は一般的に耐熱性が低いとされており、後加工時に問題になることがある。
また、反りを抑える方法としてポリカーボネート樹脂層の両面にアクリル系樹脂層を積層する積層体があるが、その積層体の片面に面衝撃を与えた際にその反対面のアクリル系樹脂層においてクラックを生じ易く、使用方法によっては問題となることがある。
すなわち、本発明は、以下の合成樹脂積層体および該合成樹脂積層体を用いた透明性材料を提供するものである。
(メタ)アクリレート共重合体(C)を5~55質量%及びポリカーボネート(D)を95~45質量%含む樹脂層(A)が積層された合成樹脂積層体であって、
前記(メタ)アクリレート共重合体(C)が、下記式(1)で示される芳香族(メタ)アクリレート単位(c1)とメチルメタクリレート単位(c2)とを5~80/20~95の質量比(c1/c2)で含み、かつ、前記(メタ)アクリレート共重合体(C)の質量平均分子量が5,000~30,000であり、
式(1)中、Xは、単結合、-C(R2)(R3)-、-C(=O)-、-O-、-OC(=O)- 、-OC(=O)O-、-S-、-SO-、-SO2-及びこれらの任意の組み合わせからなる群から選択される二価の基であり(ここで、R2及びR3は、各々独立に、水素原子、炭素数1~10の直鎖状アルキル基、炭素数3~10の分岐状アルキル基、炭素数3~10の環状アルキル基、炭素数1~10の直鎖状アルコキシ基、炭素数3 ~10の分岐状アルコキシ基、炭素数3~10の環状アルコキシ基、フェニル基又はフェニルフェニル基であり;R2及びR3は、相互に連結して、これらが結合する炭素原子と一緒になって炭素数3~10の環状アルキル基を形成していてもよい);
R1は、水素原子又はメチル基であり;
R4及びR5は、各々独立に、炭素数1~10の直鎖状アルキル基、炭素数3~10の分岐状アルキル基、炭素数3~10の環状アルキル基、炭素数1~10の直鎖状アルコキシ基、炭素数3~10の分岐状アルコキシ基、炭素数3~10の環状アルコキシ基、ハロゲン原子、フェニル基又はフェニルフェニル基であり
mは、1~10の整数であり;pは、0~4の整数であり;qは、0~5の整数である。)
前記ポリカーボネート(D)の粘度平均分子量が21,000~40,000であることを特徴とする合成樹脂積層体である。
<2> 前記樹脂層(A)のガラス転移点が110~135℃である上記<1>に記載の合成樹脂積層体である。
<3> 前記樹脂層(A)の吸水率が0.05~0.5%である上記<1>または<2>に記載の合成樹脂積層体である。
<4> 前記樹脂層(A)の厚さが10~250μmであり、前記合成樹脂積層体のトータル厚さ(X)が0.1~2.0mmであり、(A)/(X)の厚み比が0.01~0.5である上記<1>から<3>のいずれかに記載の合成樹脂積層体である。
<5> 前記基材層(B)の粘度平均分子量が21,000~40,000である上記<1>から<4>のいずれかに記載の合成樹脂積層体である。
<6> 前記樹脂層(A)および/または前記基材層(B)が紫外線吸収剤を含有する上記<1>から<5>のいずれかに記載の合成樹脂積層体である。
<7> 前記樹脂層(A)の表面上にハードコート処理を施した上記<1>から<6>のいずれかに記載の合成樹脂積層体である。
<8> 前記樹脂層(A)の表面上および前記基材層(B)の表面上にハードコート処理を施した上記<1>から<6>のいずれかに記載の合成樹脂積層体である。
<9> 前記合成樹脂積層体の片面または両面に、反射防止処理、防汚処理、耐指紋処理、帯電防止処理、耐候性処理および防眩処理、蒸着処理のいずれか一つ以上を施した上記<1>から<8>のいずれかに記載の合成樹脂積層体である。
<10> 上記<1>から<9>のいずれかに記載の合成樹脂積層体を含む透明性基板材料である。
<11> 上記<1>から<9>のいずれかに記載の合成樹脂積層体を含む透明性保護材料である。
<12> タッチパネルの電極基板に使用される上記<1>から<9>のいずれかに記載の合成樹脂積層体である。
前記(メタ)アクリレート共重合体(C)が、下記構造式(1)で示される芳香族(メタ)アクリレート単位(c1)とメチルメタクリレート単位(c2)とを5~80/20~95の質量比(c1/c2)で含み、かつ、前記(メタ)アクリレート共重合体(C)の質量平均分子量が5,000~30,000であり、前記ポリカーボネート(D)の粘度平均分子量が21,000~40,000であることを特徴とする。
よって、樹脂層Aおよび樹脂層Bの間の飽和吸水率の差は、好ましくは0.20~0.25%、より好ましくは0.15~0.10%程度である。
更に、基材層(B)の両面に樹脂層(A)を積層させた積層体は、樹脂層(A)がポリカーボネートを含むので耐衝撃性にも優れているため、その積層体の片面に面衝撃を与えてもその反対面が衝撃による破壊を起こしにくい。その上、両面側に同じ樹脂を積層させるので構造的に対称となり、反りの発生がさらに抑制されるので好ましい。
メチルメタクリレート単位(c2)は、ポリカーボネート系樹脂と良分散する効果を有し、成形体表面へ移行するため成形体の表面硬度を向上させることができる。
樹脂層(A)の厚さと合成樹脂積層体のトータル厚さ(X)の比((A)/(X))は、合成樹脂積層体の表面硬度、耐衝撃性に影響する。つまり、厚み比が小さすぎると表面硬度が低くなり好ましくない。厚み比が高すぎると耐衝撃性が悪くなり好ましくない。厚み比は好ましくは0.01~0.5である。より好ましくは0.015~0.4である。
さらに好ましくは0.02~0.3である。
ハードコートの密着性を向上させる目的でハードコート前に塗布面の前処理を行うことがある。処理例として、サンドブラスト法、溶剤処理法、コロナ放電処理法、クロム酸処理法、火炎処理法、熱風処理法、オゾン処理法、紫外線処理法、樹脂組成物によるプライマー処理法などの公知の方法が挙げられる。
製造例で得られた積層樹脂の物性測定、および実施例ならびに比較例で得られた合成樹脂積層体の評価は以下のように行った。
あらかじめ標準ポリスチレンをクロロホルムに溶かしてゲルパーミエーションクロマトグラフィ(GPC)で測定した検量線を基準にして、(メタ)アクリレート共重合体とポリカーボネート樹脂を同様にGPCで測定した。両者の比較により、それぞれの粘度平均分子量を算出した。GPCの装置構成は以下の通り。

展開溶媒:クロロホルム
流速:1ml/min

ポリカーボネート樹脂を塩化メチレンに溶解し(濃度6.0g/L(リットル))、ウベローデ粘度管を用いて、20℃における比粘度ηsp)を測定し、下記の式(2)および(3)により粘度平均分子量(Mv)を算出した。下記式中、Cは濃度を表し、[η]は極限粘度を表す。
JIS-K7209 A法に準処し吸水率測定を行った。まず射出成型で作成した100mm×100mm×3.0mmの試験片を作成し、それを50℃のオーブンに入れて乾燥させた。24時間後、試験片をオーブンから取り出し、23℃に温調したデシケーター中で冷却した。1時間後、試験片の重量を測定し、その後23℃の水中に投入した。24時間後、水中から試験片を取り出し、表面の水分を拭き取った後重量を測定した。水中投入後の重量と乾燥直後の重量の差を乾燥直後の重量で除し、その値に100を乗じることで、吸水率(飽和吸水率)を算出した。
