Description
前記両面粘着シートは、一方の面に凹または凸を有し、他方の面に該一方の面の凹に対応する凸または該一方の面の凸に対応する凹を有する湾曲形状となるように賦形されていることを特徴としている。
前記両面粘着シートは、一方の面に凹または凸を有し、他方の面に該一方の面の凹に対応する凸または該一方の面の凸に対応する凹を有する湾曲形状となるように賦形されていることを特徴としている。
両面粘着シートの一例としての両面粘着テープ1は、図1Aに示すように、非平面形状を有するように賦形されている。
粘着体を幅20mm、長さ100mmのサイズにカットし、一方の粘着剤層に、裏打ち用PETフィルム(厚みが25μm)を貼り合わせることにより、測定サンプルを作製する。次いで、接着力を測定する粘着剤層の粘着面を、2kgローラー、1往復で被着体(ステンレス板(SUS304BA板))に圧着し、23℃×50%RHの環境下に30分間放置する。放置後、万能引張圧縮試験機(装置名「引張圧縮試験機TG-1kN」、ミネベア社製)を用いて、引張速度300mm/min、剥離角度180°で、測定サンプルを引き剥がして、接着力を測定する。なお、この測定は23℃×50%RHの環境下で実施される。
次に、両面粘着テープ1の製造方法について説明する。
次に、図3A〜図3Cを参照して、両面粘着テープ1による、第1被着体の一例としての設置対象物20と、第2被着体の一例としての部品21との接合について説明する。
次に、図4を参照して、本発明の両面粘着テープの第2実施形態について説明する。なお、第2実施形態では、上記した第1実施形態と同様の部材には同様の符号を付し、その説明を省略する。
次に、図5Aおよび図5Bを参照して、本発明の両面粘着テープの第3実施形態および第4実施形態について説明する。なお、第3実施形態および第4実施形態では、上記した第1実施形態と同様の部材には同様の符号を付し、その説明を省略する。
次に、図6を参照して、本発明の両面粘着テープの第5実施形態について説明する。
上記の第1実施形態〜第4実施形態では、図2A〜図2Dに示すように、粘着体2および1対の剥離フィルム3を備える加工シート9を準備した後、加工シート9の一部を、賦形装置10により、非平面形状に賦形して、両面粘着テープ1を製造するが、両面粘着テープ1の製造方法は、これに限定されない。
