Abstract
本发明涉及一种易揭取的聚酰亚胺弹性导热胶带，包括泡棉(1)、导热材料(2)、粘结胶(3)、基材(4)与离型膜(5)；离型膜(5)在粘结胶(3)胶面的中间位置一分为二，且多出一部分用于捏取，捏取部分相互重贴但不粘合。本发明解决了聚酰亚胺胶带因为材料柔软易碎而不易揭取的难题，并增加了导热和弹性功能。
Description
技术领域
本发明属于胶带领域，特别涉及一种易揭取聚酰亚胺弹性导热胶带。
背景技术
目前的聚酰亚胺胶带基本全是离型膜与产品胶面完全贴合在一起的设计，使用时就得非常小心的从胶带边缘处轻轻地将离型膜揭起，然后贴到需要使用的地方。但是由于有些材料特别柔软，模切成品后揭取困难，特别是在手机、电子产品绝缘或者导热用方面，因为使用到的胶面面积要求很小，这就更加增加了揭取的难度，限制了聚酰亚胺胶带的应用推广。
发明内容
本发明所要解决的技术问题是提供一种易揭取聚酰亚胺弹性导热胶带，该胶带解决了聚酰亚胺胶带因为材料柔软易碎而不易揭取的难题，同时又增加了一层导热膜和弹性膜，增加了聚酰亚胺胶的导热和弹性功能，使其能更好的满足各种场合的使用需求。
本发明的一种易揭取聚酰亚胺导热胶带，所述聚酰亚胺弹性导热胶带包括泡棉、导热材料、粘结胶、基材与离型膜；泡棉的上表面通过粘结胶与导热材料复合，导热材料的上表面通过粘结胶与基材复合，基材的上表面通过粘结胶与离型膜复合；离型膜在粘结胶胶面的中间位置一分为二，且多出一部分用于捏取，捏取部分相互重贴但不粘合。
所述泡棉为聚氨酯，厚度为3～6μm。
所述导热材料为天然石墨，厚度为5～10μm。
所述粘结胶为丙烯酸胶。
所述基材为聚酰亚胺，厚度为0.05～0.2mm。
所述离型膜为聚对苯二甲酸乙二醇酯。
所述离型膜的捏取部分与粘结胶胶面不接触。
本发明的设计在使用胶带时既能快速的揭取，又能满足电子产品等当对面积要求很小很精确时，解决其揭取困难的问题，揭取十分方便且不会接触到胶面，保证了快速揭取的同时也保护了胶面不被污染，大大提高使用率和工作效率，同时又具有一定的导热性能，使其应用范围变得更大。
有益效果
本发明很好的解决了聚酰亚胺胶带因为材料柔软易碎，模切成品后揭取困难的问题，从而保证了在揭取时易损伤胶面完整性，减少产品浪费，提高工作效率；制作方法简单易行，可以按照产品需求任意更改底膜直线刀位置，既方便揭取又有定位作用，同时增加了导热和弹性功能，使其能更好的满足各种场合的使用需求。
附图说明
图1为本发明的结构示意图。
具体实施方式
下面结合具体实施例，进一步阐述本发明。应理解，这些实施例仅用于说明本发明而不用于限制本发明的范围。此外应理解，在阅读了本发明讲授的内容之后，本领域技术人员可以对本发明作各种改动或修改，这些等价形式同样落于本申请所附权利要求书所限定的范围。
实施例1
如图1所示，本实施例提供了一种易揭取的聚酰亚胺弹性导热胶带，所述聚酰亚胺弹性导热胶带包括泡棉1、导热材料2、粘结胶3、基材4与离型膜5；泡棉1的上表面通过粘结胶3与导热材料2复合，导热材料2的上表面通过粘结胶3与基材4复合，基材4的上表面通过粘结胶3与离型膜5复合；离型膜5在粘结胶3胶面的中间位置一分为二，且多出一部分用于捏取，捏取部分相互重贴但不粘合。离型膜5完全盖住与空气接触的一层胶面。泡棉1为聚氨酯，厚度为5μm；导热材料2为天然石墨，厚度为8μm；粘结胶3为丙烯酸胶；基材4为聚酰亚胺，厚度为0.1mm，离型膜5为聚对苯二甲酸乙二醇酯。用于捏取的离型膜5可以轻易翻起但又不会触碰到粘结胶3的胶面。
本实施例揭取十分方便且不会接触到胶面，保证了快速揭取的同时也保护了胶面不被污染，同时因为导热材料的加入，使其功能增加，应用范围也更加广泛。
