Description
本発明に使用する発泡体基材としては、密度が0.45g/cm3以下、好ましくは0.1g/cm3〜0.45g/cm3、より好ましくは0.15g/cm3〜0.42g/cm3であるものを使用することができる。前記範囲の密度を有する発泡体基材を使用することで、一定の力が加わった際の好適な解体性を備えた両面粘着テープを得ることができる。
本発明の両面粘着テープは、それを構成する前記発泡体基材の両面に前記樹脂フィルムからなる層を有する。前記樹脂フィルムは、それぞれ同一のものであってもよく、異なる材質や厚さからなるものであってもよい。
本発明に使用する粘着剤層は、厚さ25μmの表面平滑なポリエチレンテレフタレート基材に厚さ25μmの粘着剤層を設けて形成した粘着テープを、温度23℃、相対湿度65%RHの環境下で表面平滑なアルミニウム板に対し、2kgローラー(JIS−Z0237に記載のもの)を使用して圧着回数一往復で圧着し、温度23℃、相対湿度50%RHの環境下に1時間静置した後の剥離速度300mm/minにおける180°引き剥がし接着力が10N/20mm以上、好ましくは12N/20mm以上の粘着剤層である。当該粘着剤層を使用することで、好適な耐衝撃性と共に、解体時に良好に発泡体基材の層間割れを実現でき、一定の力での好適な解体性を実現できる。接着力の上限は特に制限されないが、25N/20mm以下であることが好ましく、20N/20mm以下であることがさらに好ましい。
サンプル注入量:100μl
溶離液:THF
流速:1.0ml/分
測定温度:40℃

本発明の両面粘着テープは、特定の発泡体基材と特定の粘着剤層とともに樹脂フィルムを積層することによって得られるものであり、薄型の構成であっても好適な耐衝撃性を有すると共に、一定の力が加わった際には発泡体基材が層間割れを生じて好適に解体でき、かつ、解体後に被着体の表面に残存した糊などの残存物を容易に剥離し取り除くことのできる両面粘着テープである。このため、小型電子機器の部品固定用途、特に、小型電子機器の情報表示部の保護パネルや画像表示モジュール、薄型電池などの解体時に大きな力が加わりやすい板状剛体部品の固定用途に好適に適用できる。

発泡体基材の両面に、厚さ50μmの強粘着性(下記高速剥離試験時に被着体および発泡体基材から剥離しないもの)の粘着剤層を1枚ずつ貼り合わせたのち、40℃で48時間熟成し、層間強度測定用の両面粘着テープを作製した。次に、片側の粘着面を厚さ25μmのポリエステルフィルムで裏打ちした幅1cm、長さ15cm(発泡体基材の流れ方向と幅方向)の両面粘着テープ試料を、23℃及び50%RH下で厚さ50μm、幅3cm、長さ20cmのポリエステルフィルムに2kgローラー1往復で加圧貼付し60℃で48時間静置した。23℃で24時間静置後、23℃及び50%RH下で厚さ50μmのポリエステルフィルムと貼り合わせた側を高速剥離試験機の取り付け治具に固定し、厚さ25μmのポリエステルフィルムを引張速度15m/分で90度方向に引っ張り発泡体を引き裂いた際の最大強度を測定した。
発泡体基材の流れ方向と幅方向の引張強さは、JISK6767に準じて測定した。標線長さ2cm、幅1cmの発泡体基材を、テンシロン引張試験機を用い、23℃及び50%RHの環境下において、引張速度300mm/minの測定条件で測定した。得られた測定値の最大強度が発泡体基材の引張強度である。
発泡体基材の25%圧縮強度は、JISK6767に準じて測定した。25角に切断した試料を厚さ約10mmになるまで重ね合わせた。発泡体基材より大きな面積のステンレス板で発泡体基材をはさみ、23℃下で10mm/分の速度で発泡体基材を約2.5mm(もとの厚さの25%分)圧縮した時の強度を測定した。
まず、発泡体基材を幅方法、流れ方向とも1cmに切断した。次に、切断した発泡体基材の切断面中央部分をデジタルマイクロスコープ(商品名「KH−7700」、HiROX社製)により、発泡体気泡部分を200倍に拡大したのち、発泡体基材の幅方向または流れ方向の断面を発泡体基材の切断面がその基材厚さ方向の全長を観察した。得られた拡大画像において、流れ方向または幅方向の拡大前の実際の長さが2mm分の切断面に存在する気泡の気泡径を全て測定し、その平均値から平均気泡径を算出した。任意の10カ所で測定した結果から平均気泡径を求めた。
1)実施例及び比較例で得た両面粘着テープを、長さ2cm(発泡体基材の流れ方向)、幅1cmに裁断した。それを、縦2.5cm、横4.0cm、2mm厚のポリカーボネート板の中心に幅方向に2cmの間隔をあけて2枚貼付した。
○:両面粘着テープの9割以上10割未満が発泡体基材の層間で破壊して剥離された。
×:両面粘着テープの発泡体基材の層間で破壊した部分が9割未満であった。
上記易解体性の試験後、各被着体の表面に残った両面粘着テープの一部(残存物)の端部をつまみあげ、135°方向に600mm/minでゆっくりと手剥がしにて剥離した。具体的には、前記ポリカーボネート板(被着体B)の表面に残った両面粘着テープの一部と、前記アルミニウム板(被着体A)の表面に残った両面粘着テープの一部の剥離のしやすさを、上記手剥がしにて評価した。
○:両面粘着テープの残存物の9割以上10割未満が、被着体の表面から剥離除去された。
△:両面粘着テープの残存物の5割以上〜9割未満が、被着体の表面から剥離除去された。
であった。
×:両面粘着テープの残存物の5割未満が、被着体の表面から剥離除去された。
1)厚さ2mm、外形50mm×50mmのアクリル板(三菱レイヨン(株)アクリライトL「商標名」、色相:透明)に、長さ40mm、幅5mmの2枚の両面粘着テープの弱粘着面を40mmの間隔をあけて平行に貼付(図1)したのち、厚さ2mm、外形150mm×100mmのABS板(住友ベークライト株式会社製、タフエースR「商標名」色相:ナチュラル、シボなし、以下同じ)の中央部に貼付した(図2)。2kgローラーで1往復加圧したのち、23℃で1時間静置して試験片とした。
×:高さ60cm以下でテープの剥がれ又は破壊が生じた
