【選択図】なし
Description
本実施の形態における樹脂組成物は、少なくとも(A)ポリ乳酸と(B)ホスファゼン化合物と、(C)結晶核剤と、を含む。
ポリ乳酸は、植物由来であり、環境負荷の低減、具体的にはCO2の排出量削減、石油使用量の削減効果がある。ポリ乳酸としては、乳酸の縮合体であれば、特に限定されるものではなく、ポリ−L−乳酸(以下「PLLA」ともいう)であっても、ポリ−D−乳酸(以下「PDLA」ともいう)であっても、それらが共重合やブレンドにより交じり合ったものでもよく、さらに、ポリ−L−乳酸とポリ−D−乳酸とを混合したものであり、これらのらせん構造がうまく噛み合った耐熱性の高い、ステレオコンプレックス型ポリ乳酸(以下「SC−PLA」ともいう)であってもよい。また、ポリ乳酸は、合成したものを用いてもよいし、市販品を用いてもよい。前記市販品としては、例えば、ユニチカ(株)製の「テラマックTE4000」、「テラマックTE2000」、「テラマックTE7000」、三井化学(株)製の「レイシアH100」等が挙げられる。また、ポリ乳酸は、1種単独で用いてもよいし2種以上を併用してもよい。なお、本実施形態において、ポリ乳酸は樹脂組成物の主成分として含まれる。ここで「主成分」とは、樹脂組成物全量に対して50質量%を超えることを意味する。
本実施の形態に用いられるホスファゼン化合物は、分子中に「−P=N−結合」を有する有機化合物で、好ましくは、環状フェノキシホスファゼン、鎖状フェノキシホスファゼン、フェノキシホスファゼンが用いられる。中でも耐湿熱性の観点から、環状フェノキシホスファゼンが好ましい。環状フェノキシホスファゼンとしては、商業的に入手可能なものとして、例えば、「FP−100」、「FP−110」、「FP−200」(伏見製薬工業所製、商品名)、「SP−100」、「SP−100H」(大塚化学社製、商品名)等が挙げられる。
本実施の形態に用いられる結晶核剤としては、一般に樹脂の結晶核剤として用いられるものを特に制限なく用いることができ、無機系の結晶核剤および有機系の結晶核剤のいずれをも使用することができる。無機系の結晶核剤の具体例としては、タルク、カオリナイト、モンモリロナイト、合成マイカ、クレー、ゼオライト、シリカ、グラファイト、カーボンブラック、酸化亜鉛、酸化マグネシウム、酸化チタン、硫化カルシウム、窒化ホウ素、炭酸カルシウム、硫酸バリウム、酸化アルミニウム、酸化ネオジウムおよびフェニルホスホネートの金属塩などが挙げられる。これらの無機系の結晶核剤は、組成物中での分散性を高めるために、有機物で修飾されていることが好ましい。
本実施の形態に用いられる多官能化合物は、ポリ乳酸の末端基(例えば、カルボキシル基、水酸基等)と反応する官能基を2つ以上持つ化合物である。
本実施の形態における樹脂組成物は、その他、酸化防止剤、安定剤、紫外線吸収剤や充填剤を含有してもよい。
本実施の形態における樹脂組成物は、(A)ポリ乳酸と(B)ホスファゼン化合物と、(C)結晶核剤と、必要に応じて(D)多官能性化合物と、更に必要に応じてその他成分とを、混練して作製される。
本実施の形態における成形体は、上述した本実施の形態における樹脂組成物を成形することにより得ることができる。例えば、射出成形、押し出し成形、ブロー成形、熱プレス成形などの成形方法により成形して、本実施形態に係る成形体が得られる。本実施形態においては、成形体における成分の分散性の理由から、本実施形態の樹脂組成物を射出成形して得られたものであることが好ましい。
前述の本実施の形態における成形体は、成形性、耐湿熱性に優れたものになり得るため、電子・電気機器、家電製品、容器、自動車内装材などの用途に好適に用いることができる。より具体的には、家電製品や電子・電気機器などの筐体、各種部品など、ラッピングフィルム、CD−ROMやDVDなどの収納ケース、食器類、食品トレイ、飲料ボトル、薬品ラップ材などであり、中でも、電子・電気機器の部品に好適である。電子・電気機器の部品は、複雑な形状を有しているものが多く、また重量物であるので、重量物ではない場合に比べて高い耐衝撃強度及び面衝撃強度が要求されるが、本実施形態の樹脂成形体によれば、このような要求特性を十分満足させることができる。
表1に示す実施例1から実施例16に示す組成を、2軸混練装置(東芝機械製、TEM58SS)にて、シリンダ温度190℃で混練し、樹脂組成物ペレットを得た。得られたペレットを射出成形機(日精樹脂工業製、NEX150)にて、シリンダ温度200℃、金型温度100℃で、ISO多目的ダンベル試験片(ISO527引張試験、ISO178曲げ試験に対応)(試験部厚さ4mm、幅10mm)を成形した。
還流冷却器、温度計及び撹拌機を備えた3リットルのフラスコにp−メトキシフェノール441g(3.55モル)を量り取り、THF(1.5リットル)を加えて均一になるまで撹拌した。そこへ金属ナトリウム74g(3.2グラム原子)を50℃以下で投入し、投入終了後1時間かけて60℃まで昇温し、その後60℃〜68℃で4時間撹拌して、p−メトキシフェノールナトリウム塩のTHF溶液を得た。
得られた試験片を用いて、下記各評価を行った。表1に結果を示す。
ISO多目的ダンベル試験片をノッチ加工したものを用い、JIS K7111に準拠して、デジタル衝撃試験機(東洋精機製、DG−5)により、持ち上げ角度150度、使用ハンマー2.0J、測定数n=10の条件で、MD方向にシャルピー衝撃強度を測定した。シャルピー衝撃強度は、数値が大きい程、耐衝撃性に優れていることを示す。
((湿熱試験後のシャルピー衝撃強度)/(湿熱試験前のシャルピー衝撃強度))×100をシャルピー衝撃強度の維持率(%)とし、耐湿熱性の指標としてこれを評価した。(表中では「シャルピー維持率(%)」で表す。)△以上を合格とする。
◎:湿熱試験後のシャルピー衝撃強度が湿熱試験前のシャルピー耐衝撃強度の90%以上
○:湿熱試験後のシャルピー衝撃強度が湿熱試験前のシャルピー耐衝撃強度の70%以上90%未満
△:湿熱試験後のシャルピー衝撃強度が湿熱試験前のシャルピー耐衝撃強度の50%以上70%未満
×:湿熱試験後のシャルピー衝撃強度が湿熱試験前のシャルピー耐衝撃強度の50%未満、またはシャルピー衝撃強度が1kJ/m2未満
ISO多目的ダンベル試験片の成形体成形条件(日精樹脂工業製、NEX150、成形温度200℃、保持時間50秒)における、金型温度が80℃、90℃、100℃の場合の金型と樹脂成形体との離型性について評価した。△以上を合格とする。
○:非常に離れ易い(試験片の変形がなく、金型からの取り出しが容易)
△:若干離れ難い(試験片の変形が若干あり、金型からの取り出しが困難)
×:離れない(試験片の変形が大きい)
表1に示す比較例1から比較例3に示す組成を、実施例と同様に樹脂組成物ペレットを得て、試験片の成形、各評価を実施した。結果を表1に示す。
