Abstract

本發明提供一種UV解粘壓敏膠組合物和包含其的膠帶。UV解粘壓敏膠組合物包含聚丙烯酸酯壓敏膠、可紫外光聚合的聚氨酯型寡聚物、陽離子型光引發劑和自由基型光引發劑，其中聚丙烯酸酯壓敏膠的聚合單體包含具有環氧官能團的丙烯酸類單體。該UV解粘壓敏膠組合物在紫外光照射後粘接力大幅下降，並且沒有殘膠。

Description

一種UV解粘壓敏膠組合物和壓敏膠帶
本發明涉及壓敏膠領域，具體涉及UV解粘壓敏膠組合物和包含其的壓敏膠帶。
可紫外光解粘的壓敏膠也稱為UV解粘膠，是指一類可以通過UV光激發導致粘接力降低的壓敏膠。UV解粘膠具有施工方便，初始粘結力高，UV解粘後易於移除的特點。UV解粘膠可以用於半導體加工，作為晶圓切割的臨時固定與保護膠帶。其也可以用於外觀件在製造加工過程中的臨時保護。其還可以應用在柔性電路板的製成輸運膠帶。其良好的粘接力，可以保證柔性電路板在化鎳化金過程中不會脫落，同時經過解粘後易於移除，防止了柔性電路板在移除保護膠帶時因為粘接力過大而導致的形變。其還可以應用在醫療領域，普通的醫用膠帶長期貼在皮膚上，粘接力會逐漸變大。對於部分皮膚比較脆弱的區域，移除普通醫用膠帶會導致皮膚撕裂。醫用的UV解粘膠可以通過低劑量的UV光照射降低粘接力，降低病人在膠帶移除時的痛苦。相比於傳統保護膜，UV解粘膠在保護工程中粘接力更高，並且在解粘後更容易移除。
現有的UV解粘膠典型地由壓敏膠，可紫外光聚合的寡聚物（也稱為UV寡聚物，或解粘樹脂）和自由基型光引發劑組成。壓敏膠提供初始的粘接力。當受到紫外光照射時，UV寡聚物在自由基型光引發劑作用下發生交聯反應，使得解粘膠整體的模量提高。這樣，膠層變硬並且失去粘接力。
然而，現有的解粘膠組合物在進行解粘時，壓敏膠與UV寡聚物的相互作用通常僅有分子鏈相互作用。壓敏膠與UV寡聚物的相互作用不足常常導致壓敏膠未受UV寡聚物的影響，進而導致在局部形成殘膠，或者粘接力下降不足乃至異常變大。
在一個方面，本發明提供一種UV解粘壓敏膠組合物，所述UV解粘壓敏膠組合物包含： 20至80重量份的聚丙烯酸酯壓敏膠，所述聚丙烯酸酯壓敏膠的聚合單體包含具有環氧官能團的丙烯酸類單體； 20至80重量份的可紫外光聚合的聚氨酯型寡聚物，所述可紫外光聚合的聚氨酯型寡聚物在紫外聚合後的玻璃化轉變溫度為60℃以上； 0.1至5重量份的陽離子型光引發劑；和 0.1至5重量份的自由基型光引發劑。
在一個實施方案中，所述可紫外光聚合的聚氨酯型寡聚物在紫外聚合後的玻璃化轉變溫度為90℃以上。
在一個實施方案中，所述具有環氧官能團的丙烯酸類單體占所述聚丙烯酸酯壓敏膠的聚合單體的0.1重量%-10重量%。
在一個實施方案中，所述具有環氧官能團的丙烯酸類單體包含丙烯酸縮水甘油醚或甲基丙烯酸縮水甘油醚。
在一個實施方案中，所述聚丙烯酸酯壓敏膠的聚合單體還包含不具有環氧官能團的選自丙烯酸酯和丙烯酸的單體。
在一個實施方案中，所述可紫外光聚合的聚氨酯型寡聚物在25℃下的粘度為1000 mPa•s至100,000 mPa•s。
在一個實施方案中，所述UV解粘壓敏膠組合物還包含溶劑。
在另一個方面，本發明提供一種壓敏膠帶，所述膠帶包含： 基底膜；和 在所述基底膜上的前述UV解粘壓敏膠組合物的層。
在一個實施方案中，所述基底膜選自：聚烯烴膜、聚對苯二甲酸乙二醇酯膜、聚醚醚酮膜、聚醯胺膜、和聚氨酯膜。
本發明提供一種UV解粘壓敏膠組合物，所述UV解粘壓敏膠組合物包含： 20至80重量份的聚丙烯酸酯壓敏膠，所述聚丙烯酸酯壓敏膠的聚合單體包含具有環氧官能團的丙烯酸類單體； 20至80重量份的可紫外光聚合的聚氨酯型寡聚物，所述可紫外光聚合的聚氨酯型寡聚物在紫外聚合後的玻璃化轉變溫度為60℃以上； 0.1至5重量份的陽離子型光引發劑；和 0.1至5重量份的自由基型光引發劑。
與常規的UV解粘膠相比，本發明的解粘膠組合物中的聚丙烯酸酯壓敏膠的聚合單體包含具有環氧官能團的丙烯酸類單體，並且選用聚氨酯型寡聚物和陽離子型光引發劑，其中所述聚氨酯型寡聚物在紫外光聚合後的玻璃化轉變溫度為60℃以上，較佳地在90℃以上。在聚丙烯酸酯壓敏膠合成時引入具有環氧官能團的單體，可以使得所得的聚丙烯酸酯壓敏膠在陽離子型光引發劑的作用下也發生快速UV交聯固化。聚丙烯酸酯壓敏膠固化和上述聚氨酯型寡聚物引起的固化同時發生，形成獨特的紫外光雙固化機制。此外，選擇上述聚氨酯型寡聚物作為UV寡聚物，可以在發生交聯反應的同時，與聚丙烯酸酯壓敏膠上的環氧基團發生化學作用。這樣，當使用UV進行解粘時，本發明的解粘膠組合物同時經歷聚丙烯酸酯壓敏膠交聯反應、寡聚物交聯反應、以及聚丙烯酸酯壓敏膠與寡聚物相互作用。這三個過程協同發生，帶來多種優點。首先，傳統UV解粘膠在發生解粘反應時，壓敏膠難以與解粘樹脂形成有效的相互作用，導致殘膠、局部粘接力變大等問題。本發明通過在聚丙烯酸酯壓敏膠中設置環氧基團並選擇特定的聚氨酯型寡聚物，可以有效避免這些問題。同時，相對於傳統UV解粘膠，具有環氧基團的聚丙烯酸酯壓敏膠樹脂本身也可以通過陽離子型光引發劑的交聯機制固化，從而提升壓敏膠的模量，以進一步降低粘接力。
本發明的壓敏膠組合物中的聚丙烯酸酯壓敏膠是由丙烯酸類聚合單體聚合而成的。可以使用任何本領域習知的可以聚合製備聚丙烯酸酯壓敏膠的丙烯酸類聚合單體，只要其與本發明的原則沒有衝突即可。本發明的特徵在於聚丙烯酸酯壓敏膠的聚合單體必須包含具有環氧官能團的丙烯酸類單體。如上所述，具有環氧官能團的丙烯酸類單體提供雙固化機制以及與聚氨酯型寡聚物的有益相互作用。
具有環氧官能團的丙烯酸類單體可以占所述聚丙烯酸酯壓敏膠的聚合單體的0.1重量%-10重量%。當具有環氧官能團的丙烯酸類單體在此範圍內時，提供良好的解粘效果，同時不影響解粘前壓敏膠組合物的粘結性，並且從成本上是有利的。
具有環氧官能團的丙烯酸類單體的較佳實施例包括丙烯酸縮水甘油醚或甲基丙烯酸縮水甘油醚。
聚合單體還可以包含不具有環氧官能團的選自丙烯酸酯和丙烯酸的單體。在本文中，如無特別說明，丙烯酸酯和丙烯酸也包括甲基丙烯酸酯和甲基丙烯酸。丙烯酸酯可以是例如丙烯酸烷基酯，如丙烯酸甲酯、甲基丙烯酸甲酯、丙烯酸-2-乙基乙酯、丙烯酸丁酯等，和取代的丙烯酸烷基酯，如丙烯酸羥乙酯等。
本發明的壓敏膠組合物中的可紫外光聚合的聚氨酯型寡聚物是一種具有碳碳雙鍵的寡聚物。其在紫外聚合後的玻璃化轉變溫度應為60℃以上。具有此性能的聚氨酯型寡聚物具有優秀的通過紫外光交聯降低粘接力的能力。如果使用紫外聚合後的玻璃化轉變溫度過低的聚氨酯型寡聚物，得到的產品粘結力下降不夠，不易解粘。
聚氨酯型寡聚物在25℃下的粘度為1000m Pa•s至100,000m Pa•s。具有此粘度的聚氨酯型寡聚物與聚丙烯酸酯壓敏膠的主鏈上的環氧基團發生更好的相互作用，可以更好地避免殘膠出現。
聚氨酯型寡聚物可以是可商購的產品，如沙多瑪公司的CN8000NS、CN9006NS、CN983NS，長興化學的6145-100等等。
本發明的壓敏膠組合物中包含的陽離子型光引發劑和自由基型光引發劑可以是任何合適的光引發劑，只要其與本發明的原則沒有衝突即可。
本發明的壓敏膠組合物中的聚丙烯酸酯壓敏膠、可紫外光聚合的聚氨酯型寡聚物、陽離子型光引發劑和自由基型光引發劑的重量比例為20-80:20-80:0.1-5:0.1-5。在此範圍內時，本發明的壓敏膠組合物可以同時具有良好的粘結性和良好的解粘性能。
本發明的壓敏膠組合物還可以包含適當的溶劑。溶劑用於為壓敏膠組合物提供良好的混合。在將壓敏膠組合物製成製品如膠帶後，可以將溶劑蒸發掉。
本發明的壓敏膠組合物初始粘接力高，並且解粘後無殘膠。UV解粘後，粘結力可以下降90%以上。
本發明還提供一種壓敏膠帶，所述膠帶包含： 基底膜；和 在所述基底膜上的前述UV解粘壓敏膠組合物的層。
基底膜可以選擇任何合適的基底膜，特別是用於保護的基底膜。合適的基底膜的實例可以包括聚烯烴膜、聚對苯二甲酸乙二醇酯膜、聚醚醚酮膜、聚醯胺膜、聚氨酯膜等。聚烯烴膜可以是例如聚丙烯膜或聚乙烯膜。
本發明的壓敏膠帶可以通過在基底膜上塗布本發明的UV解粘壓敏膠組合物製備得到。該壓敏膠帶具有UV解粘功能。其初始粘接力高，並且解粘後無殘膠。UV解粘後，粘結力可以下降90%以上。本發明的壓敏膠帶可以用於半導體加工、外觀件在製造加工、柔性電路板加工、以及醫療等領域中。
