Abstract
Description
本出願は、2011年5月17日出願の仮特許出願第61/487,092号、2011年7月15日出願の同61/508,232号および2011年12月12日出願の同61/569,422号の優先権を主張し、その開示全体が参照により本明細書に組み込まれる。
1)二層積層体をプラスチック基材上に真空形成させる場合、二層積層体を180〜210℃に加熱することがある。接着が不十分であると、TPOがブリスタリングを起こして高温において発泡体と分離する可能性がある。
2)TPO−発泡体二層積層体をインストルメントパネルに使用する場合、二層積層体は、展開の際に二層積層体を突き破るエアバッグを収納している縫い目線に沿ってきれいに裂ける必要がある。TPOとの接着が不十分であると、展開の際に二層積層体中の発泡体とTPOが望ましくない形で分離する可能性がある。
ポリマーの「メルトフローインデックス(MFI)」値は、ASTM D1238に従って定義され、ポリエチレンおよびポリエチレン系材料に関しては190℃にて、ポリプロピレンおよびポリプロピレン系材料に関しては230℃にて、2.16kgのプランジャーを10分間使用して測定する。メルトフローが比較的高い樹脂に関しては試験時間を少なくしてもよい。MFIは「樹脂メルトフローレート」と呼ぶこともある。
1)発泡体と接触させる前にTPOの積層面を加熱する温度
2)TPOと接触させる前にポリプロピレン発泡体の積層面を加熱する温度
3)積層の際にTPOおよび発泡体に加える圧力
4)TPOの成分
5)ポリプロピレン発泡体の成分
6)TPO内において物理的または化学的架橋を行う場合はその量および種類
7)ポリプロピレン発泡体内における物理的架橋の量および種類
8)TPOとポリプロピレン発泡体の相溶性および/またはポリマー鎖の絡み合いおよび/または混和度
9)TPOの積層面の粗さまたは滑らかさ(TPOシートを個別に製造する場合)
10)ポリプロピレン発泡体の積層面の粗さまたは滑らかさ
1)積層装置が、TPOの積層面および/またはポリプロピレン発泡体の積層面を積層に最も望ましい温度に加熱するように設計されていない場合がある。
2)積層装置が、積層の際にTPOおよび発泡体に最も望ましい圧力を加えるように設計されていない場合がある。
3)ラミネーターが、ポリプロピレンとの質の高い接着にはあまり好ましくない特定のTPO配合物に限定されている場合がある。
4)TPOおよび発泡体製造装置が、TPOおよび/またはポリプロピレン発泡体内における架橋の量および種類を特定した内装トリム製造装置であり、その量および種類が良好な積層にはあまり好ましくない場合のある内装トリム製造装置に限定されている場合がある。
積層工程Aにおいては、積層の前に発泡体面を加熱しておく。加熱した発泡体の上にTPOを直接押し出した後、両者を引っ張ってニップを通し、積層体を作成する。
積層工程Bにおいては、積層の前に発泡体面を加熱しない。積層の約1週間前にTPOスキンを個別に製造しておく。積層工程Bにおいては、TPOスキンを加熱した後、加熱したTPOと未加熱の発泡体を一緒に引っ張ってニップを通し、積層体を作成する。
積層工程Cにおいては、積層の前に発泡体面を加熱しない。積層の約1週間前にTPOスキンを個別に製造しておく。積層工程Cにおいては、TPOスキンを加熱した後、加熱したTPOと未加熱の発泡体を一緒に引っ張ってニップを通し、積層体を作成する。
積層工程Dにおいては、積層の前に発泡体面を加熱しない。積層の約1週間前にTPOスキンを個別に製造しておく。積層工程Dにおいては、TPOスキンを加熱した後、加熱したTPOと未加熱の発泡体を一緒に引っ張ってニップを通し、積層体を作成する。
