Description
よって、本発明は、アクリル系ポリマー、イオン液体及び高吸水性高分子を含む、電気剥離性粘着剤組成物が提供される。
本発明によれば、芯材と、芯材の両面にそれぞれ接するように形成された2つの電気剥離性粘着剤層とを有し、電気剥離性粘着剤層が、上記の電気剥離性粘着剤組成物を含む、電気剥離性粘着製品が提供される。

ガラス転移温度は、例えば、示差熱分析(DTA)により測定することができる。
アクリル系モノマーには、炭素数1~14のアルキル基を有するアルキル(メタ)アクリレートが主成分(50重量%以上)として含まれていることが好ましい。なお、(メタ)アクリレートは、メタクリレート又はアクリレートを意味する。
任意に使用される重合開始剤としては、例えば、2,2’-アゾビスイソブチロニトリル、2,2’-アゾビス(2-メチルプロピオンアミジン)二硫化物、2,2’-アゾビス(4-メトキシ-2,4-ジメチルバレロニトリル)、2,2’-アゾビス(2,4-ジメチルバレロニトリル)、2,2’-アゾビス(2-メチルブチロニトリル)、1,1’-アゾビス(シクロヘキサン-1-カルボニトリル)、2,2’-アゾビス(2,4,4-トリメチルペンタン)、ジメチル-2,2’-アゾビス(2-メチルプロピオネート)、2,2’-アゾビス[2-メチル-N-(フェニルメチル)-プロピオンアミジン]ジハイドロクロライド、2,2’-アゾビス[2-(3,4,5,6-テトラハイドロピリミジン-2-イル)プロパン]ジハイドロクロライド及び2,2’-アゾビス[2-(2-イミダゾリン-2-イル)プロパン]等のアゾ系重合開始剤;過硫酸カリウム及び過硫酸アンモニウム等の過硫酸塩系重合開始剤;ベンゾイルパーオキサイド、過酸化水素、t-ブチルハイドロパーオキサイド、ジ-t-ブチルパーオキサイド、t-ブチルパーオキシベンゾエート、ジクミルパーオキサイド、1,1-ビス(t-ブチルパーオキシ)-3,3,5-トリメチルシクロヘキサン、1,1-ビス(t-ブチルパーオキシ)シクロドデカン、3,3,5-トリメチルシクロヘキサノイルパーオキサイド及びt-ブチルペルオキシピバレイト等の過酸化物系重合開始剤;過硫酸塩と亜硫酸水素ナトリウムとにより構成されたレドックス系重合開始剤等が挙げられる。これらの重合開始剤は、1種のみ使用してもよく、2種以上組み合わせて使用してもよい。また、紫外線照射、放射線照射を行ってもよい。重合開始剤は、アクリル系モノマー100重量部に対して0.005~1重量部の範囲で使用することが好ましい。この範囲で重合開始剤を使用することで、粘着特性に優れたアクリル系ポリマーを形成できる。
イオン液体は、室温で液体であるカチオンとアニオンとの組み合わせであり、常温溶融塩とも呼ばれる。イオン液体は、不燃性、不揮発性及び化学的安定性等の特性を有する。イオン液体は、電圧を印加することで、陽極側にアニオンが移動し、陰極側にカチオンが移動する。電極付近へのアニオン及びカチオンの移動、又は電極と電気剥離性粘着剤組成物との界面でアニオン又はカチオンの酸化還元反応が起こることで、電気剥離性粘着剤組成物の粘着力が弱まり、その結果、剥離性が向上すると考えられている。

本実施形態の電気剥離性粘着剤組成物には、導電材、充填材、可塑剤、酸化防止剤、難燃剤、着色剤、界面活性剤又は上記アクリル系ポリマー以外の粘着剤等の添加剤が含まれていてもよい。
本実施形態の電気剥離性粘着剤組成物は、アクリル系ポリマー、イオン液体、高吸水性高分子及び任意で移動促進剤、架橋剤等を攪拌することにより製造できる。攪拌方法としては、特に限定されず、公知の攪拌方法を用いることができる。具体的には、例えばアクリル系ポリマー、イオン液体、高吸水性高分子及び任意で移動促進剤、架橋剤等をV型混合機やミキサー(ディゾルバー、ホモミキサー、プラネタリーミキサー等)によって攪拌することが挙げられる。攪拌時に、上記の添加剤が加えられていてもよい。
本実施形態の電気剥離性粘着剤組成物は、高温条件下に晒されても優れた電気剥離性を有している。そのため、電気剥離性が低下するため従来の電気剥離性粘着剤組成物が使用できなかった電気剥離性粘着剤組成物が高温になり得る条件下での使用に適している。そのような条件下としては、例えば車のエンジンまわりや、家電の駆動部周辺、電子部品や金属部品の製造時等が挙げられる。
本実施形態の電気剥離性粘着製品(以下、単に粘着製品ともいう)は、基材と、基材に接するように形成された電気剥離性粘着剤層によって構成される。また、粘着製品の別の形態としては、芯材と、芯材の両面にそれぞれ接するように形成された2つの電気剥離性粘着剤層によって構成される。
ここで、固定とは、直接的な固定と間接的な固定とがあり、直接的な固定とは、被着体及び固定対象物が粘着製品と直接接している状態を指し、間接的な固定とは、被着体及び/又は固定対象物が粘着製品と直接触れず、導電性補助材を介して接している状態を指す。固定対象物が被着体に固定できるのであれば、固定方法は直接的な固定であっても間接的な固定であっても構わない。
粘着製品に用いられる基材としては、例えば、アルミニウム、銅、銀、金等の金属、又はこれらの金属の合金からなる箔又は板、ポリエチレンテレフタレート(PET)やポリイミドのフィルム、炭素繊維、紙、織布又は不織布等が挙げられ、厚みも特に限定されない。ただし、粘着製品に用いられる非導電性の基材は、剥がして使用する。これらは、用いる電気剥離性粘着製品の形状によって適切になるように選択することができる。基材又は芯材は、塗布した電気剥離性粘着剤組成物がそのまま基材又は芯材の表面に付着するものでもよいし、基材又は芯材の繊維間の隙間などにしみ込むようなものであってもよい。そのような基材としては、例えば紙や不織布などが挙げられる。
基材又は芯材を用いることによって、粘着製品に強度を持たせることができ、使用時の作業性を向上できる。
本発明の一実施形態は、電気剥離性粘着製品の製造方法である。電気剥離性粘着製品は、例えば電気剥離性粘着剤組成物を基材又は芯材に塗布して電気剥離性粘着剤層を形成することで製造できる。電気剥離性粘着剤組成物、電気剥離性粘着剤層、基材、電気剥離性粘着製品及び塗布方法については、上述の通りである。
本実施形態の電気剥離性粘着剤層及び粘着製品は、導電性の物体上に電気剥離性粘着剤層又は粘着製品を貼り付けた後、電圧を印加することにより、電気剥離性粘着剤層又は粘着製品を直接貼り付けた導電性の物体から剥離できる。
アクリル系ポリマー、イオン液体、移動促進剤及び高吸水性高分子を用いて、以下のようにして粘着製品を作製した。
1. アクリル系ポリマーの調製
n-ブチルアクリレート(三菱ケミカル社)91重量部、アクリル酸(三菱ケミカル社)8重量部及び2-ヒドロキシエチルメタクリレート(日本触媒社)1重量部からなるモノマー混合物と、重合溶媒(酢酸エチル:トルエン(重量比)=9:1)186重量部を、ガラス製フラスコに投入し、窒素ガスで置換した後、重合開始剤としてアゾビスイソブチロニトリル(AIBN、純正化学社)0.2重量部を加え、85℃に昇温して5時間重合反応させて、アクリル系粘着剤を得た。得られたアクリル系粘着剤は、アクリル系ポリマー(重量平均分子量約80万、Tg-46℃)を35重量%含み、7,000mPa・sの粘度を有していた。
上記アクリル系粘着剤100重量部(アクリル系ポリマー35重量部)にイソシアネート系架橋剤としてのコロネートL-55E(東ソー社)5.0重量部と、移動促進剤としてジメチルテトラグリコール(日本乳化剤社:分子量約220)7.0重量部とを室温で10分間ディゾルバーにより撹拌した。攪拌後、イオン液体としてエレクセル(登録商標)AS-110(EMI-FSI:第一工業製薬社)7.0重量部を更に加えて室温で10分間ディゾルバーにより撹拌した。2回目の攪拌後、高吸水性高分子としてアクアリックCS 6S(登録商標:日本触媒社)を1.75重量部添加し、同様に室温で10分間ディゾルバーにより撹拌し静置脱泡することで電気剥離性粘着剤組成物を得た。
2.で得られた電気剥離性粘着剤組成物を、表面をシリコーン処理したポリエチレンテレフタレートのフィルムに塗布し、100℃で5分間乾燥させた。乾燥後のフィルムの電気剥離性粘着剤組成物の塗布面を不織布[ミライフ(登録商標)TY0503FE(ENEOSテクノマテリアル社)]に貼り付けた。同様に、表面をシリコーン処理したポリエチレンテレフタレートのフィルムに電気剥離性粘着剤組成物を塗布・乾燥させたフィルムを作製し、不織布のフィルムを貼り付けていない面に貼り付けた。その後、40℃で3日間静置することで実施例1の粘着製品(両面テープ、厚さ80μm)を得た。
高吸水性高分子を用いないこと以外は実施例1と同様にして比較例1の粘着製品を得た。
高吸水性高分子の量をアクリル系粘着剤100重量部に対して3.5重量部としたこと以外は実施例1と同様にして実施例2の粘着製品を得た。
高吸水性高分子の量をアクリル系粘着剤100重量部に対して7.0重量部としたこと以外は実施例1と同様にして実施例3の粘着製品を得た。
高吸水性高分子をサンフレッシュ(登録商標)ST-500MPSA(三洋化成工業社)としたこと以外は実施例1と同様にして実施例4の粘着製品を得た。
厚さ3mm、長さ50mm、幅30mmのABS樹脂板(固定対象物)の片面に、市販の電気剥離性を有さない両面テープ(ビッグテクノス社製RD-7020)を貼り付けた。両面テープのABS樹脂を貼り付けていない側に、厚さ50μmのアルミ箔(導電性補助材)を貼り付けた。アルミ箔を貼り付けた後、アルミ箔のABS樹脂と市販の両面テープの両方が貼り付いている領域のアルミ箔を挟んだ逆側に、50mm×30mmの長さになるように切り出された実施例1~4、比較例1の各粘着製品の片面の剥離フィルムを剥がして貼り付けた。粘着製品のもう片面の剥離フィルムを剥がし、研磨したステンレス板(導電性の被着体:125mm×50mm)に貼り付けた。これに対して2kgのゴムローラを用いて300mm/分の速度で粘着製品の長辺方向に1往復させることで被着体、粘着製品及び固定対象物を圧着して評価サンプルとした。評価サンプルの概略図を図8Aに示す。図8Aのように、両面テープとアルミ箔は、ABS樹脂や粘着製品よりも長い50mm以上の長さを有しており、後述する引上げ強度測定試験を行うことができるように、オートグラフ(登録商標)のつかみ具が評価サンプルの両面テープとアルミ箔のみが重なった部分をつかめるだけの長さを有している。なお、図8A(及び図8B、図8C)の10はステンレス板、11は粘着製品、12はアルミ箔、13は両面テープ、14はABS樹脂をそれぞれ意味する。
実施例1~3、比較例1の各評価サンプルを、評価サンプル毎に30個用意し、作製した各評価サンプルを恒温恒湿機に入れ、40℃、湿度50%の条件下で100時間静置し、各評価サンプルの状態が均一になるように調製した。
引上げ強度測定試験には、島津製作所製オートグラフ(登録商標)AGS-Hを用いた。評価サンプルの両面テープとアルミ箔の部分のみが重なった部分の一部をつかみ具でつかみ、300mm/分の一定の速度で引き上げ、被着体から粘着製品(及び固定対象物)を剥がすのに必要な力を測定した(図8B及びCを参照)。
印加試験は、評価サンプルの導電性の被着体側が正極、固定対象物側が負極になるように電極を取り付けて行った。直流電源を用い、変圧器を用いて電圧を調整して、評価サンプルに30Vの電圧を60秒間印加した。
実施例1、2及び比較例1の各評価サンプルを、評価サンプル毎に24個用意し、加熱促進試験の温度を80℃とすること以外は加熱促進試験1と同様にして加熱促進試験を行い、0時間、24時間、48時間及び100時間の各評価サンプルを回収して引上げ強度の測定を行った。
