Description

雙面重覆黏貼膜片
本創作係有關於一種雙面膜片結構，特別是一種在可重覆黏貼之使用的雙面膜片結構。
按，習知產品雙面重覆黏貼之膜片結構，主要用於在各種不同表面(如牆面、磁磚、玻璃等)，重覆黏貼之膜片結構係提供黏貼裝飾圖案或是連接各種吊掛物件等功能。不論用於一般家庭或是各種商業用途，以往多以各種型態的黏膠作為黏貼之方式，目前在市面上具黏性膠存在著多種不同的產品態樣，例如以美商3M生產的一般膠帶、雙面膠帶、易撕型膠帶、惰性膠等，然而，就多數膠帶所採用的膠劑而言，在使用上無法有反覆黏貼使用的問題，並亦即容易在黏貼之表面留下殘餘之黏膠，或者一旦被黏貼過後，其黏性即大幅喪失而無法還原再使用，除了造成清理與美觀上的問題之外，適合使用的地方亦受到相當大侷限。
習知美國專利US 20070020474號所述之一種雙面黏著薄膜，該薄膜包括一支持薄膜、一第一黏著劑層係積層於該支持薄膜的一面，以及一第二黏著劑層係積層於該支持薄膜的另一面，其中該第一黏著劑層及該第二黏著劑層的硬化後之玻璃轉移溫度小於等於100℃。因此該第一黏著劑層與該第二黏著劑層係呈現為膠狀，黏貼後不易進行剝離，且不具有重覆黏貼之特性，另一缺點 為黏著劑層為膠狀且該黏著劑層之玻璃轉移溫度一定要小於等於100℃，亦即該黏著劑層在高溫狀態超過100℃時該黏著劑層膠狀立即凝固為硬化不具黏著性。
再如一習知台灣專利TW 201105765號所述之一種具有再剝離性的黏著材，該黏著材包括一基材層與至少二個黏著劑層，其中該基材層之一面與該黏著劑層之間具有一內部剝離界面，且該內部剝離界面之剝離強度與該黏著劑層和被黏體之間的剝離強度不同。因此該黏著材雖具有雙面黏貼以及重覆黏貼之特性，但是因為黏著界面之剝離強度不同，若被黏著物品須承受負載力時(如掛鉤)，容易因為黏著度不佳而脫落。因此針對雙面重覆黏貼結構，仍有更進一步發展與改進之空間。
有鑑於上述缺憾，創作人有感其未臻於完善，遂竭其心智悉心研究克服，憑其從事該項產業多年之累積經驗，進而研發出一種雙面重覆黏貼膜片，利用簡單的設計，可使本創作達到穩定黏貼以及可重覆使用之功效。
本創作之主要目的，即在設計一種雙面重覆黏貼膜片，其中該雙面重覆黏貼膜片包含第一膜層及第二膜層，其中該第一膜層與該第二膜層的表面係產生具有複數個微氣泡結構係使該第一膜層及該第二膜層具有重覆黏貼使用之功效。
本創作之另一主要目的，為一種雙面重覆黏貼膜片，其中該 雙面重覆黏貼膜片第一膜層與該第二膜層係經高溫固化過程之玻璃轉換溫度為120~240℃，用以形成該第一膜層與該第二膜層具有重覆黏貼使用之功效。
為達上述目的，本創作之實現技術如下：一種雙面重覆黏貼膜片，包含：一基材；第一膜層，係附著於該基材之一表面，以及；第二膜層，係附著於該基材之相對一表面；其特徵為該第一膜層與該第二膜層經高溫固化過程之玻璃轉換溫度為120~240℃，以形成該第一膜層與該第二膜層。
上述之雙面重覆黏貼膜片，其中，該第一膜層與該第二膜層之表面分別具有複數個微氣泡結構，以增加黏著力。
上述之雙面重覆黏貼膜片，其中，該第一膜層之厚度為0.05~0.2公分。
上述之雙面重覆黏貼膜片，其中，該第二膜層之厚度為0.05~0.2公分。
上述之雙面重覆黏貼膜片，其中，該第一膜層與該第二膜層分別進一步包含一離型紙層。
上述之雙面重覆黏貼膜片，其中，該基材之材料為聚對苯二甲酸乙二酯(polyethylene terephthalate，簡稱PET)、聚乙烯(polyethylene，簡稱PE)、聚酯層(特多龍)、金屬材質或木材材質。
上述之雙面重覆黏貼膜片，其中，該第一膜層和該第二膜層之材料為苯乙烯彈性膜層(SEBS)。
為使本創作之上述和其他目的、特徵及功效能更明顯易懂， 茲藉由下述具體之實施例，並配合所附之圖式，對本創作做一詳細說明如下。
為使本領域熟知技藝者能理解並據以實施本發明，以下係配合圖式及元件符號詳細說明之，但不以此為限。
請參閱第一圖，第一圖為本創作雙面重覆黏貼膜片實施例之結構分解圖，如圖一所示，本創作之雙面重覆黏貼膜片1主要由一基材10、第一膜層20以及第二膜層30所組成，其中該基材10之材料為聚對苯二甲酸乙二酯(polyethylene terephthalate，簡稱PET)，其一表面與該第一膜層20黏合，其相對一表面與該第二膜層30黏合；其中該第一膜層20與該第二膜層30的材料為苯乙烯彈性膜層(SEBS)，並在製備該第一膜層20及該第二膜層30的混膠過程中係經一高溫固化之玻璃轉換溫度為120~240℃之間，在此高溫下，其混膠體經高溫固化而形成膜層，且該第一膜層20及該第二膜層30各層厚度係為0.2公分之間，而上述高溫製備過程以形成的該第一膜層20及該第二膜層30，可具多次重複黏貼的功能而不造成餘膠殘留，以提高膜片使用上之便利性，上述該第一膜層20及該第二膜層30各層厚度係進一步替換為0.05~0.2公分之間，但不在此限。其中上述本實施例中該基材10之材料可進一步替換為聚乙烯(polyethylene，簡稱PE)、聚酯層(特多龍)、金屬材質或木材材質，不在此設限。
請參閱第二圖，第二圖為第一圖之雙面重覆黏貼膜片另一實 施例之改良結構分解圖，如圖二中所示，本創作之雙面重覆黏貼膜片1主要由一基材10、第一膜層20以及第二膜層30所組成，其中該第一膜層20與該第二膜層30在混膠製備過程中經高溫固化之玻璃轉換溫度為120℃，並於該高溫固化製程中產生該第一膜層20及該第二膜層30的表面分別形成具複數個微氣泡結構21、31，其中該複數個微氣泡結構21、31如同具一真空吸盤功能，當該微氣泡結構21、31與其他表面進行黏貼時以提升該雙面重覆黏貼膜片1之表面張力，以獲得更佳吸附力、更穩固效果的膜層結構，而上述實施例中該第一膜層20與該第二膜層30的材料為苯乙烯彈性膜層(SEBS)，上述該高溫固化之玻璃轉換溫度係為120~240℃之間，不在此設限，上述該第一膜層20及該第二膜層30各層厚度係0.05~0.2公分之間，不在此設限，上述實施例中該基材10之材料可進一步替換為聚乙烯(polyethylene，簡稱PE)、聚酯層(特多龍)、金屬材質或木材材質，不在此設限。
請參閱第三圖，第三圖為第一圖之雙面重覆黏貼膜片另一實施例之結構分解圖，如圖所示，本創作之雙面重覆黏貼膜片1之該第一膜層20與該第二膜層30分別進一步包含一離型紙層40，在上述該雙面重覆黏貼膜片1未使用時，該離型紙層40可以保護該第一膜層20與該第二膜層30不受外物附著汙染，以保持該第一膜層20與該第二膜層30的吸附力，待需要使用時才將該離型紙層40撕下，以進行黏貼使用，接續上述之雙面重覆黏貼膜片實施例，其中該基材10之材料可進一步替換為聚乙烯(polyethylene， 簡稱PE)、聚酯層(特多龍)、金屬材質或木材材質，故上述實施例該基材10變化材料不在此設限。
