Abstract
Description
本発明の特に有利な一実施態様によれば、層Aのための加工助剤として、エチレンベースの無水マレイン酸−修飾されたポリマー、特に無水マレイン酸修飾されたポリエチレン−アルキルアクリラート−コポリマーが使用される。
(a)少なくとも1つの熱可塑性ポリエステルを含有する材料をシートに押出、これにより、少なくとも1つの層Aが形成される、
(b)熱可塑性に加工可能なデンプンを含有する材料をシートに押出、これにより、少なくとも1つの層Bが形成される、及び
(c)少なくとも部分的な、この個々の層の平面的な結合、これにより、多層シートが形成される。
中間層(層B)のための熱可塑性デンプンの製造
天然のジャガイモデンプン(63質量%)、グリセリン(23質量%)及びソルビトール(14質量%)からなる混合物を二軸押出機中に充填した。この混合物を押出機中で温度範囲130〜160℃で強力に混合し、その際この溶融物を同時に脱ガスしてこの混合物から水を取り出した。この結果、均質な溶融物が生じ、これは注ぎ出しかつ造粒化されることができる。この記載される様式で均質化された、熱可塑性に加工可能な材料の水含有量は、3〜4質量%である。
三層シート(平面シート)の製造
ポリ乳酸(PLA)/熱可塑性デンプン(TPS)/PLAからなる三層シート(A−B−A)が製造された。デンプンとして実施例1で製造された、水含有量3〜4質量%を有する熱可塑性グリセリン/ソルビトール−デンプンを使用した。この使用したポリ乳酸(PLA顆粒、 Nature Works)は、D割合1.4%を有した。
酸素(O2):15.5cm3/m2 d
二酸化炭素(CO2):2.1cm3/m2 d。
予備混合した中間層(層B)を有する実施例2に応じた三層シートの製造
実施例2に記載した様式と同様に、外側層(A)としてPLAを有する三層シートA−B−Aを製造した。中間層(B)のために、実施例1に応じて製造したTPS顆粒(90質量%)及びPLA顆粒(10質量%)からなる予備混合物を調製し、これを一軸押出機に供給し、150〜190℃で溶融した。中間層のための押出機は100rpmで、流量25kg/h及び質量圧力120barで運転した。これに並行して、第2の一軸押出機(温度185〜200℃、回転数20rpm、質量圧力130bar、流量10kg/h)中で、PLAを溶融させた(溶融温度175℃)。この両方の溶融物をCoexアダプタ中で一緒にし、その際実施例2に記載したとおり、PLA−溶融物流を分配し、そして、半分ずつ、このデンプン層の上又は下に導通した(→外側層A)。このようにして産生された三層系を、幅広スリットノズル(T=190℃)を介して、温度処理可能なローラー(T=35℃、V=2.7m/min)を用いて取り出し、特定の幅に切断し、ロールへと巻いた。
中間層(層B)のための修飾した熱可塑性デンプンの製造
天然のジャガイモデンプン(56.5質量%)、グリセリン(20.5%)及びソルビトール(13%)及びPLA(10%)からなる混合物を二軸押出機中に充填した。この混合物を押出機中で温度範囲130〜160℃で強力に混合し、その際この溶融物を同時に脱ガスしてこの混合物から水を取り出した。実施例1と同様に、均質な溶融物が生じ、これは注ぎ出しかつ造粒化されることができる。この記載される様式で均質化された、熱可塑性に加工可能な材料の水含有量は、3〜4質量%である。
中間層(層B)において変更された熱可塑性デンプンを有する適用例2に応じた三層シートの製造
適用例2及び3に記載した様式と同様に、外側層(A)としてPLAを有する三層シートA−B−Aを製造した。中間層(B)のために、実施例4中に記載した、熱可塑性に加工可能なデンプン/PLAコンパウンドを押出機に供給し、140〜195℃で溶融させた。中間層のための押出機は90rpmで、流量25kg/h及び材料圧力115barで運転した。
実施例2と同様に、しかしながら、外側層のための乳酸(PLA)に、約3質量%の無水マレイン酸で官能化されたエチレン/メチルアクリラートポリマーを、PLA層の全体の組成に対して約1質量%の量で添加した。このようにして得られた三層シートは、実施例2に記載された生成物と比較して高められた連結を、個々の層の間で示した。
三層シート(ブローシート)の製造
ポリ乳酸(PLA)/熱可塑性デンプン(TPS)/PLAからなる三層シート(A−B−A)が製造された。デンプンとして実施例1で製造された、水含有量3〜4質量%を有する熱可塑性グリセリン/ソルビトール−デンプンを使用した。この使用したポリ乳酸(PLA顆粒、 Nature Works)は、D割合1.4%を有した。
実施例7と同様に、しかしながら、外側層のための乳酸(PLA)に、約3質量%の無水マレイン酸で官能化されたエチレン/メチルアクリラートポリマーを、PLA層の全体の組成に対して約1質量%の量で添加した。このようにして得られた三層シートは、実施例7に記載された生成物と比較して高められた連結を、個々の層の間で示した。
実施例8と同様に、しかしながら、外側層のためのポリ乳酸(PLA)に更に、PLA層の全体の組成に対して5質量%の脂肪族/芳香族コポリエステル(ECOFLEX(R) ,BASF AG)を添加した。このように得られる系は、実施例13に応じた処方物と比較してより良好な加工性を有した。
実施例7に応じた様式で、但し、約2.5質量%の水含有量を有する、実施例1に応じて製造された熱可塑性グリセリン/ソルビトール−デンプンを使用した。このように得られる系は、実施例7に対して改善された加工性を押出機中で、及び、中間層中でより少ない泡形成を有した。
