Description

散热双面胶带
技术领域
本发明涉及一种散热双面胶带。
背景技术
目前手机、平板电脑等数码产品所呈现出的轻薄化和性能强化的趋势。轻薄化意味着数码产品内部电子器件排布得越来越紧凑，富余的空间越来越狭小，而性能强化则意味着处理器芯片的运算能力越来越高，锂电池的容量越来越高，导致发热量越来越大。这两个方面的变化，均对当前的散热材料提出了更高的要求。
目前市场上用于数码类产品的散热胶带，通常是以导热性能优异的石墨片或铜箔作为基材，复合一层导热胶粘层，利用胶层和基材的热传导能力，将被贴物所产生的热量传导至基材表面，然后通过基材表面上方的空气的热对流，散去热量。这种散热方式依赖空气对流的效率，在数码产品狭小的内部空间中，由于空气对流受限，散热能力低下，效果并不理想。
发明内容
本发明的目的在于提供一种散热双面胶带，具有散热效果更佳、透气性好的优点。
本发明的技术方案是：一种散热双面胶带，所述散热双面胶带包括最外层的热辐射涂料层、中间层的粘胶层和内层的基材层，所述热辐射涂料层是由纳米二氧化硅和硅树脂组成，所述的热辐射涂料层的厚度为1-1.5mm，所述粘胶层为有机硅树脂，所述热辐射涂料层的克重为29-39g/m2，所述基材层的克重为30-40g/m2，所述粘胶层的克重为23-27g/m2。
在本发明一个较佳实施例中，所述粘胶层厚度为 1-2mm。
在本发明一个较佳实施例中，所述基材层厚度为1-3mm。
本发明的一种散热双面胶带，具有散热效果更佳、透气性好的优点。
附图说明
附图1为本发明散热双面胶带一较佳实施例的立体结构示意图。
附图中各部件的标记如下：1、最外层，2、中间层，3、内层。
具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
请参阅图1，图1是本发明一种散热双面胶带，所述散热双面胶带包括最外层1的热辐射涂料层、中间层2的粘胶层和内层3的基材层，所述热辐射涂料层是由纳米二氧化硅和硅树脂组成，所述的热辐射涂料层的厚度为1-1.5mm，所述粘胶层为有机硅树脂，所述热辐射涂料层的克重为29-39g/m2，所述基材层的克重为30-40g/m2，所述粘胶层的克重为23-27g/m2，所述粘胶层厚度为 1-2mm，所述基材层厚度为1-3mm。
有机硅树脂固化通常是通过硅醇缩合形成硅氧链节来实现的。当缩合反应在进行时，由于硅醇浓度逐渐减少，增加了空间位阻，流动性差，致使反应速率下降。因此,要使树脂完全固化,须经过加热和加入催化剂来加速反应进行。许多物质可起硅醇缩合反应的催化作用，它们包括酸和碱，铅、钴、锡、铁和其它金属的可溶性有机盐类，有机化合物如二丁基二月桂酸锡或N，N，N'，N'一四甲基胍盐等。硅树脂最终加工制品的性能取决于所含有机基团的数量（即R与Si的比值）。一般有实用价值的硅树脂,其分子组成中R与Si的比值在1．2～1．6之间。一般规律是，R：Si的值愈小,所得到的硅树脂就愈能在较低温度下固化；R：Si的值愈大，所得到的硅树脂要使它固化就需要在200~250℃的高温下长时间烘烤，所得的漆膜硬度差，但热弹性要比前者好得多。此外，有机基团中甲基与苯基基团的比例对硅树脂性能也有很大的影响。有机基团中苯基含量越低，生成的漆膜越软，缩合越快，苯基含量越高，生成的漆膜越硬，越具有热塑性。苯基含量在20～60%之间，漆膜的抗弯曲性和耐热性最好。此外，引入苯基可以改进硅树脂与颜料的配伍性，也可改进硅树脂与其它有机硅树脂的配伍性以及硅树脂对各种基材的粘附力。
在进一步说明，纳米二氧化硅的用途分非常广泛，一般添加重量在0.5—2%，个别产品体系可到10%以上。对产品性能体现的关键是：充分分散到体系当中。使用时根据不同的体系，预先将纳米二氧化硅分散在水、丙酮、醇类或其他溶剂中，对于油性体系，可辅之以助剂做预处理。主要用在以下领域，
（1）树脂复合材料：将纳米二氧化硅颗粒充分、均匀地分散到树脂材料中，可全面改善树脂基材料性能。包括：A提高强度和延伸率；B提高耐磨性和改善材料表面的光洁度；C抗老化性能。（2）塑料：利用纳米二氧化硅透光、粒度小，可以使塑料变得更加致密，在聚苯乙烯塑料薄膜中添加二氧化硅后，能提高其透明度、强度、韧性、防水性能和抗老化性能。利用纳米二氧化硅对普通塑料聚丙烯进行改性，使其主要技术指标（吸水率、绝缘电阻、压缩残余变形、挠曲强度等）均达到或超过工程塑料尼龙6的性能指标。本发明提供一种散热双面胶带，具有散热效果更佳、透气性好的优点。
本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本领域的技术人员在本发明所揭露的技术范围内，可不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。
