200846439 九、發明說明: 【發明所屬之技術領域】 本發明係關於一種再剝離用黏著片,其係於黏貼在黏 附物之後,可再剝離。 【先前技術】 以進行商品或服務之廣告宣傳爲目的,在化妝品、化 妝用品、飮料及食品等之包裝容器、設置在自動販賣機及 自動剪票機等公共場所之設備、或是電車及汽車等公共場 所所利用之車輛等,黏貼已印刷文字或影像之黏著片。針 對此等之黏著片,尋求於一定期間黏貼之後,黏著劑不會 殘留於黏附物上,且基材片不會被切斷,完美地予以剝離 之再剝離性。但是,爲了顯現再剝離性,一般而言,必須 設計減弱黏著力,黏附於具有凹凸之黏附物或彎曲面等之 情形下,會有隨時間經過而發生剝離之問題。 另一方面,以商品之品名表示,或是爲了使用者或修 理員等之操作說明書或零件替換程序爲目的,在複印機、 印表機、傳真機、個人電腦、電視、空氣調節器、冰箱及 洗衣機等之各種電器製品;大多採行碳粉匣或墨水匣等再 使用之各種關聯性製品;或構成汽車、機車及建築材料等 各種內外裝飾零件等之上,黏貼黏著片。由於此等黏著片 係長期被黏貼後而使用,因此特別要求黏貼於黏附物之期 間,黏著片與黏附物之間,並無浮動之發生或剝離之發生 (以下,將有稱爲浮動剝離之情形。),強化黏著力等之 不容易剝離黏著片的對策爲一般所施行的。 200846439 然而近年來,基於對自然環境之關懷,強烈期望循環 使用過之製品、或構成此等製品之零件的一部分或全部。 例如,藉由熱可塑性樹脂來構成各種電器製品之零件或構 件、此等各種關聯性製品之零件或構件等,以進行循環等。 具體而言,利用碎解機以將使用過之零件或構件或是超過 耐用年數之零件或構件碎解成九粒狀,將其予以加熱熔 融,再作成某些零件或構件後而予以成形,再度使用如此 之再循環成形品。於粉碎此等零件等之時,黏著片貼附於 零件等,於黏貼此黏著片之零件等與黏著片無相熔性之情 形,爲了使利用加熱熔融而不相熔之不純物所再循環的零 件強度得以不降低,將有去除黏著片之必要。因此,習知 利用吹風機加熱黏著片後而予以剝離,或利用硏磨機予以 刮除,之後,將此零件等碎裂成九粒狀,再將其熔融後而 得到再循環成形品。然而,從零件等剝離黏著片之作業係 一種既費事又費時之極爲麻煩的作業,藉此,不可避免零 Φ 件之再循環成本將上升的缺點,因此,於剝離黏著片之際, 要求黏著劑不殘留於黏附物,且基材片不會被切斷,能夠 容易地再剝離。 但是,若僅重視再剝離性的話,在各種電器製品等’ 黏貼於已實施所觀察到的壓紋加工之具有凹凸的表面之情 形,或黏貼於彎曲的黏附物之情形下,將有黏著片發生浮 動剝離的問題。另外,由於從構成各種電器製品等之熱可 塑性樹脂發生的氣體釋出,將發生於暫時所黏貼t ^著1片 200846439 與熱可塑性樹脂之間積存氣泡的問題。 爲了解決如此問題之技術,於專利文獻1中揭示一種 丙烯酸系黏著劑組成物,其特徵在於:相對於(甲基)丙 烯酸烷酯單體成分74.999〜99.9質量%、與(甲基)丙讎 酸烷酯單體成分可進行共聚合之含有羧基的單體〇〜〇〇〇1 質量%、與(甲基)丙烯酸烷酯單體成分可進行共聚合之 含有羥基的單體0.1〜5質量%、及與其他可進行共聚合之 _ 單體〇〜20質量%的單體成分進行自由基共聚合後所得的 丙烯酸系共聚物1 00重量份,含有異氰酸酯系交聯劑〇 . i 〜5重量份而成的丙烯酸系黏著劑組成物,該黏著劑組成 物乾燥皮膜的動態黏彈性光譜測定中之於1 20 °C的儲存彈 性率爲2xl05〜7xl05dyn/cm2及損失正切(tanS)爲〇.〇5 〜0.4,並且於0°C的儲存彈性率爲lxlO5〜4xl06dyn/cm2。 但是,於上述專利文獻1所揭示之黏著加工製品之情 形,雖然再剝離性爲優異的,但是於複印機、印表機、傳 • 真機或此等複合機等之影像形成裝置,或是各種電器製品 等之電子機器具有實施壓紋加工之凹凸表面,黏著力不 足,一旦黏貼後經過長期時,將有被剝離之問題點。 另外,已知一種再剝離用黏著膜(參照專利文獻2 ), 其特徵在於:相對於聚甲基丙烯酸甲酯板之1 80度撕剝黏 著力爲〇.2N/25mm〜5.0N/25mm,固定載重剝離測定法中之 3〇分鐘後的剝離長度爲50mm以下,並且將黏著膜貼於聚 甲基丙烯酸甲酯板,於常溫下放置1小時後,將撕剝速度 200846439 1 m/分鐘、撕剝角度1 8 0度撕剝時之黏著力設爲p 1,於6 0 °C放置24小時後,將撕剝速度lm/分鐘、撕剝角度180度 撕剝時之黏著力設爲P2時的P1與P2之比(P1/P2)爲1.4 〜〇·7。該技術係關於一種再剝離用黏著膜,其係具有優越 之黏接性,不會發生浮動剝離等,另外,於剝離時,黏著 劑將不會污染黏附物而具優越之再剝離性。 再者,已知一種再剝離性黏著膜(參照專利文獻3 ), _ 其係於使聚苯乙烯系膜基材、黏著劑層與剝離片予以積層 之黏著膜中,相對於聚苯乙烯系黏附物之隨時間經過的黏 接力’剝離速度 5mm/分鐘下爲2·0〜4.0N/25mm,並且剝 離速度300mm /分鐘下爲8.0〜12.0 N/25mm;及一種再剝離 型水性黏著劑組成物(參照專利文獻4 ),其特徵在於: 其係由含有聚合物粒子〔X〕與肼衍生物〔Y〕而成的水性 黏著劑組成物,其中,聚合物粒子〔X〕係由含有羰基與羧 基的酸價爲3〜30之聚合物所構成的平均粒徑爲3 00nm以 馨下者,肼衍生物〔Y〕係於分子中具有至少二個肼基,由該 再剝離型水性黏著劑組成物所形成的皮膜,其玻璃轉移溫 度爲-25 °C以下,凝膠分率爲80質量%以上,並且水萃取 物量爲2質量%以下。此等技術係關於一種具優越之黏著 性’並且貼附於黏附物後,即使於長時間放置後,也能夠 容易地從黏附物表面剝離之技術,尤其後者係有關使用乳 液型黏著劑之技術。 然而,於上述專利文獻2〜4中,針對在壓紋加工等之 200846439 表面上黏貼已實施凹凸的粗糖面情形的問題,則無任何之 記載,事實上,若黏貼於壓紋加工面等之粗糙面,經過長 期的話,黏著膜容易剝離。 另外,於專利文獻5中,已知一種容易從複印機、印 表機等之影像形成裝置或各種電子機器之零件去除黏著片 之方法,係於黏貼黏著片之區域形成溝與溝交叉的凹處, 當再循環時,利用用於分解之工具等’沿著溝而切開黏著 片,將凹處作爲記號而剝離黏著片之方法。 但是,已揭示於上述專利文獻5之方法中,於黏貼之 零件中必須實施形成凹處之加工,另外,爲了切開剝離黏 著片,若使用黏著力強的黏著片時,擔憂於剝離途中,基 材將斷裂,或黏著劑殘留於黏附物,將有剝離作業效率變 差之情形。 專利文獻1 :日本專利特開平1 1 - 1 5 8 4 5 3號公報 專利文獻2:日本專利特開20〇4-315775號公報 專利文獻3 :日本專利特開2 0 0 3 - 1 8 3 6 0 4號公報 專利文獻4 :日本專利特開2 0 0 4 - 2 7 7 7 1 1號公報 *

尤其’本發明之其他目的係在於提供一種再剝離用黏 著片’對於藉由以聚乙烯、聚丙烯、聚對苯二甲酸乙二酯、 聚苯乙嫌、聚苯醚、AB S、聚碳酸酯及此等之複合材料爲 主要成分之熱可塑性樹脂所構成的平滑表面及粗糙面,顯 | 示優越之黏著性及再剝離性,長期將不會發生浮動剝離。 再者’本發明之其他目的係在於提供一種再剝離用黏著 片’對於具有以丙烯酸系樹脂爲主要成分之表面層的平滑 表面及粗糙面,顯示優越之黏著性及再剝離性,長期將不 會發生浮動剝離。再者,本發明之其他目的係在於提供一 種再剝離用黏著片,解決上述課題,並且對於上述各被黏 著物質之彎曲面’也顯示優越之黏著性及再剝離性,長期 浮動剝離將不會發生。 • 再者,本發明之其他目的係在於提供一種黏著片,即 使從被黏接物質之熱可塑性樹脂發生氣體釋出,也不會發 生氣泡積存於黏著片與熱可塑性樹脂之間。 解」决問穎之技術丰跺 爲了解決上述課題,進行鑽硏之結果,得知使用一種 保持適度彈性與黏性均衡之黏著劑的黏著片能夠達成本發 明之目的。而且,發現長期黏貼後之浮動剝離及再剝離性 係藉由測定動態黏彈性光譜中之高溫區域的損失正切而能 -10- .200846439 夠預見,使本發明得以完成。 亦即’本發明係提供一種再剝離用黏著片,其係於基 材之至少一面具備黏著劑層的再剝離用黏著片,其特徵係 於該黏著劑層之頻率1 Η z、- 5 0〜1 5 0 °C中之動態黏彈性光 譜的損失正切爲: (a )於-2 0 C以下之低溫區域,上方具有凸的波峰; (b)於10〜40 °C之中溫區域,下方具有凸的波峰; I (c)於70C之損失正切爲〇_38〜0.57。 發明之效果 本發明之黏著片,不僅是對於黏附物之平滑面,對於 具有凹凸之粗糙面或對彎曲面也具有優越之黏著性的同 時,一旦完成黏著片之貼附時,黏著片之浮動剝離等將不 會長期發生,另外,於剝離黏著片之際,不會因黏著劑而 污染黏附物或基材片破裂。因而,適合於以下列爲前提之 用途:爲了以進行商品或服務之廣告宣傳爲目的,在化妝 • 品、化妝用品、飮料及食品等之包裝容器、自動販賣機及 自動剪票機等公共場所所設置之設備、或是電車及汽車等 公共場所所利用之車輛等,或是表示爲了使用者或修理員 等之操作說明書或零件替換程序之文字及圖案等各種影像 資訊,黏貼在複印機、印表機、傳真機、個人電腦、電視、 空氣調節器、冰箱及洗衣機等之各種電器製品;大多採行 再使用之碳粉匣、或墨水匣等各種關聯性製品·,或構成汽 車、機車及建築材料等之各種內外裝飾零件等’於一定期 -11- 200846439 間黏貼後而予以剝離。 尤其,因爲本發明之黏著片即使對於藉由以聚乙烯、 聚丙烯、聚對苯二甲酸乙二酯、聚苯乙烯、改性聚苯醚' ABS、聚碳酸酯及此等之複合材料爲主要成分之熱可塑性 樹脂所構成的平滑表面及粗糙面或彎曲面,具有優越之黏 接性的同時,也具有優越之剝離性,於再循環貼附本發明 黏著片的電器製品之情形下,於剝離黏著片之際,不會發 0 生因黏著劑而污染黏附物,或基材片被切斷,另外,因爲 剝離作業也爲容易的,作爲優越之黏著片而黏貼於以再循 環爲目的之電器製品等構件。 再者,本發明之黏著片,即使從熱可塑性樹脂發生氣 體釋出,也能夠防止於黏著片與熱可塑性樹脂之間發生氣 泡積存。尤其,於複印機、印表機、電視等之各種家電製 品中,於製品完成後,以手貼予以貼附的標籤之情形下, 較宜爲厚的標籤,若根據本發明之黏著片,由於厚的基材, φ 排斥力爲強的,因此即使爲氣泡不容易排出之厚度,也能 夠作成具有良好之再剝離性與剝離承受性,不容易發生氣 泡積存之標籤。 再者,對於具有以丙烯酸系樹脂爲主要成分之表面層 的平滑表面及粗糙面或彎曲面,因爲本發明之黏著片係顯 示優越之黏接性及再剝離性,作爲化妝品、化妝用品等之 包裝容器所使用之管子,或作爲黏貼於自動販賣機彎曲面 之再剝離用黏著片也爲優異的。 -12- 200846439 【實施方式】 實施發明之最佳形態 以下’基於其構造要件,更詳細說明本發明之再剝離 用黏著片。還有,於本專利說明書中,所謂(甲基)丙烯 酸,係指丙烯酸或甲基丙烯酸,針對丙烯酸或甲基丙烯酸 之衍生物也爲相同的。另外,所謂循環係指將使用過之製 品作爲同種或別種之製品原材料而加以再利用之情形,將 I 使用過之製品,於原狀態下或修整一部分後而再使用(rouse) 之二種情形。 (再剝離用黏著片之構造) 本發明之再剝離用黏著片係將黏著劑積層於基材片之 至少一面而成物作爲基本構造,以單面黏著片或雙面黏著 片之形式予以形成,必要時將剝離片設置於黏著劑層上。 於任一種之情形下,積層於基材片之黏著劑,可以積層在 基材片之至少一面的整面,也可以爲一部分。 • 另外’單面黏著片之情形,也可以在黏著劑層與相反 側之基材片表面進行印刷。再者,以保護其印刷面,或提 高創意性或美觀性爲目的,也可以透過黏著劑層或黏接劑 層,將透明膜或消光色調之半透明膜積層於印刷面。 (黏著劑層之動態黏彈性特性的規定方法) 構成本發明之再剝離用黏著片之黏著劑層的動態黏彈 性特性,其係根據特定頻率及特定溫度之動態黏彈性光譜 的損失正切,或根據損失正切及儲存彈性率而加以規定, -13- 200846439 再者,顯示特定頻率之動態黏彈性光譜的損失正切波峰之 溫度,或損失正切之波峰値而加以規定。於動態黏彈性之 測定中,使用黏彈性試驗機(Rheometrics公司製之商品 名:Ares 2KSTD ),於相同試驗機之測定部位的平行圓盤 之間夾入試驗片,測定於頻率1 Hz、從-5 0 °C至1 5 0 °C爲止 之儲存彈性率(G’)與損失彈性率(G”)。試驗片也可以 單獨將厚度〇·5〜2.5mm之黏著劑夾入於平行圓盤之間。還 0 有,後者之情形係僅使黏著劑之厚度成爲該範圍之方式來 加以調整。本發明人等已確認若將作爲黏著劑之厚度調整 成爲上述範圍時,即使基材被夾持於中間,對於黏著劑之 動態黏彈性光譜也不會造成影響。 構成本發明之再剝離用黏著片之黏著劑層,於頻率 1Hz下之- 5 0°C〜150°C範圍的損失正切,於- 20°C以下之低 溫區域,上方具有凸狀的波峰,從低溫區域至中溫區域減 少,於1 0〜4 0 °C之中溫區域,下方具有凸的波峰,從中溫 # 區域上升至高溫區域,採取於7 0 特定範圍內之値。 藉由將損失正切設爲上述各範圍,將適度之流動性賦 與黏著劑。具體而言,即使於黏附物表面之微小凹凸內也 發現能夠滲透之流動性的同時,由於並非過度流動,也能 夠抑制黏接力之過度上升。再者,藉由黏著劑適度流動之 性質,能夠緩和施加於黏著劑之應力。其結果,隨時間經 過或高溫環境下予以曝露後,再剝離黏貼於黏附物的黏著 片之作業中,不會發生使欲剝離之基材變得容易破裂、黏 -14- 200846439 著劑變成容易殘留於黏附物。另外’即使隨時間經過或高 溫環境下,曝露已貼附於黏附物的黏著片時’也不容易發 生黏著片之浮動剝離。再者,將黏著片黏貼於熱可塑性樹 脂之情形下,即使從熱可塑性樹脂發生氣體釋出,於黏著 片與熱可塑性樹脂之間,氣泡積存也將變得不容易發生。 (高溫區域中之黏著劑層的損失正切) 於5 0〜1 2 0 °C之高溫領域中,構成本發明之再剝離用 I 黏著片之黏著劑層在頻率1Hz、70°C的損失正切爲0.38〜 0.57。於70 °C的損失正切適宜爲0·43〜0.55,更佳爲0.46 〜〇 · 5 4。另外,於5 0 °C的損失正切適宜爲0 · 3 8〜0 · 5 3,更 佳爲0.40〜0.51。另外,於100 °C的損失正切適宜爲0.40 〜0.65,更佳爲0.44〜0.65,尤以0.50〜0.60特別理想。 再者,於120°C之損失正切適宜爲0.40〜0.66,更佳爲0.45 〜0·66。其中,尤以0.51〜0.62特別理想。 (中溫區域中之黏著劑層的損失正切) # 於頻率1Hz、10°C〜60°C之間,構成本發明再剝離用 黏著片之黏著劑層的損失正切係於下方具有凸的波峰。再 者’其波峰値適宜爲〇·35〜0.51,更佳爲0.4〜0.51。 (顯示低溫區域中之損失正切曲線的凸波峰之溫度) 於頻率1 Hz,構成本發明之再剝離用黏著片之黏著劑 層,顯示其損失正切曲線的凸波峰之溫度適宜爲_ 2 〇 t以 下,更佳爲-25 °C以下,尤以-30 °C以下特別理想。若爲此 車巷圍內’於黏貼時,黏著劑層將容易於壓紋面等之凹凸面 -15- 200846439 充分流動,其結果,與黏附物之黏接力變得足夠,隨時間 經過,浮動剝離不容易發生。另外,於進行再剝離時,不 容易顯現間斷性抗拒感,或嘎啦嘎啦之剝離聲音,能夠進 行順利的剝離作業。 (低溫區域中之損失正切的凸波峰値) 構成本發明之再剝離用黏著片之黏著劑層,其損失正 切之波峰値較宜爲1 . 3〜1 . 0以下。 (黏著劑層之貯藏彈性率) 於頻率1Hz,構成本發明之再剝離用黏著片的黏著劑 層,其於70 °C之儲存彈性率較宜爲6.0x1 04〜2.1 xl 05( Pa)。 另外,於50°C之儲存彈性率較宜爲7.0χ104〜2.4x1 05( Pa)。 另外,於 1 0 0 °C之儲存彈性率較宜爲 3.0 X 1 0 4〜1.6 X 1 0 5 (Pa)。另外,於120 °C之儲存彈性率較宜爲2.ΟχΙΟ4〜1.4 xlO5 ( Pa)。再者,於-4 0 °C之儲存彈性率較宜爲5.0x1 〇6 〜5.〇xl〇7(Pa) 〇 φ (初期黏著力) 本發明之再剝離用黏著片的初期黏著力F a較宜爲3.0 〜9.0(N/25mm)。另外,初期黏著力Fa較宜爲3.0〜8.0 (N/25mm ),其中,更佳爲 3.0 〜7.0(N/25mm)。還有, 初期黏著力Fa係以相對於依照JIS B 〇6012()()1所定義之輪 廓曲線的算術平均高度R a ( 3 )爲〇〜〇 · 1 μ m之聚苯乙燒板 成9 〇度撕剝黏接力所定義之値,該9 0度撕剝黏接力係根 據JIS Z 023 7,於壓黏速度5mm/s、壓黏次數1次來回, -16- 200846439 將貼上試驗片之試驗板,於溫度23±2°C、相對濕度50土5 %之氣體環境中放置24小時後,拉伸速度50m m/m in之條 件下所測定的値。 若初期黏著力Fa爲上述範圍時,於黏貼黏著片之期 間,剝離不容易發生。另外,於進行剝離之際,黏著劑將 殘留於黏附物,或是基材片從破壞之黏附物的剝離變得困 難也不容易發生。 0 另外,於本發明之再剝離用黏著片中,將相對於該Ra (3)爲 6.8〜7·2μιη之聚苯乙烯板的初期黏著力設爲Fb (N/25mm)時,該Fa與該Fb之關係較宜符合式(1): 0.30<Fb/Fa<l .00 ( 1 ) 初期黏著力Fb係相對於該Ra ( 3 )爲6.8〜7.2卞111之聚 苯乙烯板成90度撕剝黏接力所定義之値,90度撕剝黏接 力係根據JIS Z 02 3 7,於壓黏速度5mm/s、壓黏次數1次 來回,將貼上試驗片之試驗板,於溫度23 ±2 °C、相對濕度 • 5 0±5%之氣體環境中放置24小時後,拉伸速度50mm/min 之條件下所測定的値。還有,Fb/Fa之値更佳爲符合下式 (2),最好爲符合下式(3 )。該Fb與Fa之關係於此範 圍內,其係意指黏著片不僅對黏附物之平滑面,即使對具 有凹凸的粗糙面也具有優越之黏接性。若Fb/Fa之値爲此 範圍時,可以得到相對於具有凹凸面的粗糙面之良好黏著 力,浮動剝離不容易發生。 0.40<Fb/Fa<l .00 ( 2 ) -17- 200846439 0.50<Fb/Fa<l .00 ( 3 ) (基材片) 使用於本發明之再剝離用黏著片的基材片,不應該爲 予以特別限定之物,例如,可列舉:塑膠系薄膜、纖維素 系薄膜、不織布、紙、布或金屬箔等。 塑膠系薄膜可列舉:聚烯烴(例如,聚丙烯、聚乙烯)、 聚酯(例如,聚對苯二甲酸乙二酯、聚萘二甲酸乙二酯)、 聚苯乙烯、ABS、聚碳酸酯、聚醯亞胺薄膜、聚氯乙烯、 耐綸、聚乙烯醇等;纖維素系薄膜可列舉:賽珞凡 (cellophane)、二醋酸纖維素、三醋酸纖維素等。另外,不 織布可列舉:紙漿、螺縈、馬尼拉麻、丙烯腈、耐綸、聚 酯等;紙可列舉··高級紙、樹脂塗布紙等。尤其,單面黏 著片之情形,爲了於防止再剝離時基材片之切斷,較宜將 塑膠系薄膜作爲基材片使用。另外,關於上述材料,能夠 m II獨成分爲主要成分,也能夠使用此等之複合材料。再 # 者’以改質基材片之目的下,也可以少量添加其他成分。 例如’將聚苯乙烯使用於基材片之情形,較宜使用將聚丁 =烯少量摻合於主要成分之聚苯乙烯中,使柔軟性得以提 高之高衝擊聚苯乙烯(HIPS ),再者,以耐光性爲必要之 1青M T ’較宜使用甲基丙烯酸甲酯-苯乙烯共聚合樹脂(MS 樹脂)或丙烯腈-苯乙烯-丙烯酸共聚合樹脂(ASA樹脂) 胃t胃丙烯酸系單體的共聚合樹脂或摻合丙烯酸系樹脂之 基材片。 -18- 200846439 另外,將再剝離用黏著片使用於再循環構件的標籤等 之情形下,也較宜將使用於再剝離用黏著片之基材主要成 分作成與黏附對象之再循環構件主要成分可進行相同的再 循環處理之基材,尤以作成與黏附對象之再循環構件相同 的基材特別理想。例如,適用於黏貼在具備由以聚丙烯、 聚乙烯、聚苯乙烯、聚苯醚、AB S、聚碳酸酯及此等之複 合材料爲主要成分之熱可塑性樹脂所形成的構件之電器製 0 品等該構件的用途之情形,藉由將與該構件的主要成分相 同性質之聚丙烯、聚乙烯、聚苯乙烯、聚苯醚、AB S、聚 碳酸酯作爲基材片之主要成分,由於與該構件之相溶性將 提高,必要時不予以再剝離,黏貼黏著片之狀態下,直接 連同該構件進行材料再循環也變得可能,能夠進一步提高 再循環適合性。 例如,該構件之主要成分爲聚丙烯之情形,期望使用 聚丙烯作爲基材片之主要成分;該構件之主要成分爲聚乙 # 烯之情形,期望使用聚乙烯作爲基材片之主要成分;該構 件之主要成分爲聚苯乙烯之情形,期望使用聚苯乙烯作爲 基材片之主要成分;該構件之主要成分爲聚苯醚之情形, 期望使用聚苯醚作爲基材片之主要成分;該構件之主要成 分爲ABS之情形,期望使用ABS作爲基材片之主要成分; 該構件之主要成分爲聚碳酸酯之情形,期望使用聚碳酸酯 作爲基材片之主要成分;該構件之主要成分爲聚碳酸酯與 AB S的複合材料之情形,期望使用以聚碳酸酯、A b S、或 -19- 200846439 聚碳酸酯與abs之複合材料爲主要成分之熱可塑性樹脂所 構成的基材片。 另外,爲了抑制因來自熱可塑性樹脂之氣體釋出所造 成之黏著片與熱可塑性樹脂之間的氣泡積存,期望使用氣 體透過性優越之基材。例如,可列舉:聚丙烯、聚乙烯、 聚苯乙烯等。_ HIPS基材片之情形,拉伸斷裂強度MD較宜爲20MPa 0 以上、TD較宜爲15MPa以上。若爲上述範圍的話,進行 再剝離之際,基材並未被切斷而進行剝離將成爲可能。再 者,拉伸斷裂伸度係MD與TD較宜均爲30〜60%。若爲 上述範圍,爲了賦與適度之剛性與柔軟性,薄膜變得不容 易斷裂的同時,也變得不容易拉伸,再剝離性將進一步提 高。 基材片之拉伸斷裂強度及拉伸斷裂伸度係於溫度23 土2 °C、相對濕度50±5%之氣體環境中,在拉伸速度200mm/min #

Field of the Invention The present invention relates to an adhesive sheet for re-peeling which can be peeled off after being adhered to an adhesive. [Prior Art] For the purpose of advertising products or services, packaging containers for cosmetics, cosmetics, beverages, foods, etc., equipment installed in public places such as vending machines and automatic ticket machines, or trams and automobiles. Adhesive sheets for printed characters or images are attached to vehicles used in public places. For these adhesive sheets, it is sought that after the adhesive is applied for a certain period of time, the adhesive does not remain on the adhesive, and the substrate sheet is not cut, and the peeling property is perfectly peeled off. However, in order to exhibit re-peelability, in general, it is necessary to design a weak adhesive force, and if it adheres to an adhesive or a curved surface having irregularities, there is a problem that peeling occurs over time. On the other hand, in the name of the product, or for the purpose of the user or the repairer's operating instructions or parts replacement procedures, in copiers, printers, fax machines, personal computers, televisions, air conditioners, refrigerators and Various electrical appliances such as washing machines; most of them are used in various related products such as toner cartridges or ink cartridges; or on various interior and exterior decorative parts such as automobiles, locomotives and building materials, and adhered to adhesive sheets. Since these adhesive sheets are used after being adhered for a long time, it is particularly required that during the adhesion to the adhesive, there is no floating occurrence or peeling between the adhesive sheet and the adhesive (hereinafter, there will be called floating peeling). In the case of the adhesion, it is generally practiced to remove the adhesive sheet. 200846439 However, in recent years, based on the care for the natural environment, it is strongly desired to recycle the products or parts or parts of the parts constituting the products. For example, parts or members of various electrical products, parts or members of these various related products, and the like are formed by a thermoplastic resin to perform circulation or the like. Specifically, a disintegrator is used to disassemble used parts or components or parts or components that exceed the number of years of durability into nine-grain shapes, heat-melt them, and then form them into certain parts or components. Reuse such recycled molded articles again. When the parts or the like are pulverized, the adhesive sheet is attached to the parts and the like, and the parts to which the adhesive sheet is pasted and the adhesive sheet are not melted, and the parts to be recycled by the impurities which are melted without being melted by heating are melted. The strength is not reduced and there is a need to remove the adhesive sheet. Therefore, it is conventionally known that the adhesive sheet is heated by a hair dryer, peeled off, or scraped off by a honing machine, and then the part or the like is broken into nine particles, which are then melted to obtain a recycled molded article. However, the operation of peeling the adhesive sheet from a part or the like is a troublesome and time-consuming operation which is extremely troublesome, whereby the recycling cost of the zero Φ piece is inevitably increased, and therefore, when the adhesive sheet is peeled off, it is required The adhesive does not remain on the adhesive, and the base material sheet is not cut, and can be easily peeled off again. However, if only the re-peelability is emphasized, there will be an adhesive sheet in the case where various electrical products or the like are adhered to the surface having the uneven surface on which the observed embossing has been performed, or in the case of sticking to the curved adhesive. A problem with floating stripping occurred. Further, since the gas generated from the thermoplastic resin constituting various electric products and the like is released, there is a problem that air bubbles are temporarily accumulated and a bubble is accumulated between the one piece of 200846439 and the thermoplastic resin. In order to solve the problem of the above-mentioned problem, Patent Document 1 discloses an acrylic adhesive composition characterized in that it is 74.999 to 99.9% by mass based on the (meth)acrylic acid alkyl ester monomer component, and (meth)propene. The acid alkyl ester monomer component can be copolymerized with a carboxyl group-containing monomer 〇~〇〇〇1% by mass, and the (meth)acrylic acid alkyl ester monomer component can be copolymerized with a hydroxyl group-containing monomer 0.1 to 5 mass. %, and 100 parts by weight of the acrylic copolymer obtained by radical copolymerization with other monomer components of copolymerization - 20% by mass of the copolymerizable monomer, containing an isocyanate crosslinking agent 〇. i ~ 5 The acrylic adhesive composition in the form of a weight, the storage elastic modulus at 1 20 ° C in the dynamic viscoelastic spectrum measurement of the dried film of the adhesive composition is 2 x 105 - 7 x 105 dyn / cm 2 and the loss tangent (tan S) is 〇 〇5 〜 0.4, and the storage modulus at 0 ° C is lxlO5 ~ 4xl06dyn / cm2. However, in the case of the adhesive-processed product disclosed in the above-mentioned Patent Document 1, the re-peelability is excellent, but it is an image forming apparatus such as a copying machine, a printer, a transmission machine, or a multi-functional machine or the like. An electronic device such as an electric appliance has an uneven surface on which embossing is performed, and the adhesive force is insufficient, and once it has been pasted for a long period of time, there is a problem of being peeled off. Further, an adhesive film for re-peeling (refer to Patent Document 2) is known, which is characterized in that the peeling adhesion force of 1 to 80 degrees with respect to the polymethyl methacrylate sheet is 〇.2N/25 mm to 5.0 N/25 mm, The peeling length after 3 minutes in the fixed load peeling measurement method was 50 mm or less, and the adhesive film was attached to a polymethyl methacrylate plate, and after being allowed to stand at room temperature for 1 hour, the peeling speed was 200846439 1 m/min, When the peeling angle is 180 degrees, the adhesive force when peeling is set to p1, and after standing at 60 °C for 24 hours, the peeling speed is lm/min, the peeling angle is 180 degrees, and the adhesive force is set to P2. The ratio of P1 to P2 (P1/P2) is 1.4 to 〇·7. This technique relates to an adhesive film for re-peeling which has excellent adhesiveness, does not cause floating peeling, and the like, and the adhesive does not contaminate the adhesive at the time of peeling, and has excellent removability. Further, a re-peelable adhesive film (refer to Patent Document 3) is known, which is based on an adhesive film in which a polystyrene film substrate, an adhesive layer, and a release sheet are laminated, and is different from polystyrene. Adhesion of the adhesive over time 'peeling speed is 2·0~4.0N/25mm at 5mm/min, and peeling speed is 8.0~12.0 N/25mm at 300mm/min; and a re-peelable type of water-based adhesive The object (refer to Patent Document 4) is an aqueous adhesive composition comprising a polymer particle [X] and an anthracene derivative [Y], wherein the polymer particle [X] is composed of a carbonyl group. The polymer having an acid value of 3 to 30 with a carboxyl group has an average particle diameter of 300 nm. The anthracene derivative [Y] has at least two mercapto groups in the molecule, and the re-peelable type is adhered to the water. The film formed by the agent composition has a glass transition temperature of -25 ° C or lower, a gel fraction of 80% by mass or more, and an amount of water extract of 2% by mass or less. These techniques are related to a technique that is excellent in adhesion and adheres to the adherent and can be easily peeled off from the surface of the adhesive even after standing for a long period of time, especially the latter technique for using an emulsion type adhesive. . However, in the above-mentioned Patent Documents 2 to 4, there is no description about the problem that the rough sugar surface on which the unevenness has been applied is adhered to the surface of 200846439 such as embossing, and in fact, it is adhered to the embossed surface or the like. Rough surface, the adhesive film is easily peeled off after a long period of time. Further, Patent Document 5 discloses a method of easily removing an adhesive sheet from a component of an image forming apparatus such as a copying machine or a printer or various electronic devices, and forming a recess in which a groove and a groove intersect in a region where the adhesive sheet is adhered. When recycling, the adhesive sheet is cut along the groove by means of a tool for decomposition, and the concave portion is used as a mark to peel off the adhesive sheet. However, in the method of the above-mentioned Patent Document 5, it is necessary to perform the processing for forming the concave portion in the pasted part, and in order to cut the adhesive sheet, if the adhesive sheet having a strong adhesive force is used, it is feared that the base is peeled off. The material will break, or the adhesive will remain on the adhesive, which will result in poor peeling efficiency. Patent Document 1: Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei.

Further, another object of the present invention is to provide an adhesive sheet which does not cause bubbles to accumulate between the adhesive sheet and the thermoplastic resin even if the gas generated from the thermoplastic resin to be adhered is released. In order to solve the above problems, it has been found that the use of an adhesive sheet which maintains a moderately elastic and viscous adhesive can achieve the object of the present invention. Moreover, it has been found that the floating peeling and re-peelability after long-term adhesion can be achieved by measuring the loss tangent of the high temperature region in the dynamic viscoelastic spectrum. -200846439 It is foreseen that the present invention can be completed. That is, the present invention provides an adhesive sheet for re-peeling, which is a re-peelable adhesive sheet having an adhesive layer on at least one side of a substrate, and is characterized by a frequency of the adhesive layer of 1 Η z, - 5 0 The loss tangent of the dynamic viscoelastic spectrum at ~150 °C is: (a) in the low temperature region below -2 0 C, with a convex peak above; (b) in the medium temperature region of 10 to 40 °C, There is a convex peak below; I (c) at 70C, the loss tangent is 〇_38~0.57. EFFECTS OF THE INVENTION The adhesive sheet of the present invention is not only a smooth surface for an adhesive, but also has a superior adhesion to a rough surface having a concave or convex surface or a curved surface, and the floating of the adhesive sheet once the attachment of the adhesive sheet is completed. Peeling or the like will not occur for a long period of time, and when the adhesive sheet is peeled off, the adhesive or the substrate sheet is not broken by the adhesive. Therefore, it is suitable for the following premise: for the purpose of advertising for goods or services, in public places such as packaging containers, vending machines, and automatic ticket machines for cosmetics, cosmetics, cosmetics, foods, and the like.
