Description
技术领域
本发明涉及一种卷材，具体涉及一种人工石墨高导膜连续成卷的卷材。
背景技术
石墨膜主要以片状形式生产，这给后期的模切加工带来了不便，特征是材料的实际利用率无法提高，片状的石墨膜在模切前需要将石墨膜一片接一片的贴于保护膜或静电膜上从而形成卷装结构，再加以切割。但目前主要存在的问题是，将片状石墨膜一片接一片的贴于保护膜或静电膜上时，片与片之间的距离无法控制，造成石墨膜片与片之间的距离不等，无法控制切割精度，容易出现废品，无形中提高了生产成本。
发明内容
本发明针对上述问题提出了一种人工石墨高导膜连续成卷的卷材，通过长尺寸的人工石墨高导膜，极大的提高了生产效率，与此同时，人工石墨高导膜无间隙的贴合在静电膜上，直接切割即可使用，提高了精度，避免出现废品，减少了人工，降低了成本。
具体的技术方案如下：
一种人工石墨高导膜连续成卷的卷材，包括石墨膜卷材和静电层卷材，石墨膜卷材贴合吸附在静电膜上卷曲形成卷状结构；
所述石墨膜卷材由石墨材质的第一骨架层、第二骨架和连接条结合形成人工石墨高导膜的骨架结构；
所述第一骨架层至少设置两层，每层第一骨架层的第一骨架之间通过两个连接条相连接，相邻两层第一骨架层中相对应的第一骨架之间通过两个连接条相连接，所述第一骨架的截面形状为正八边形结构，第二骨架的截面形状为圆形结构，且第一骨架的边长为L1，第一连接条的长度为L2，L1＞L2，使相邻两层第一骨架层中呈2*2分布的四个第一骨架之间形成八边形结构的缓冲腔，所述第二骨架设置在缓冲腔中，第二骨架的外壁与第一骨架外壁相接触。
上述一种人工石墨高导膜连续成卷的卷材，其中，所述第一骨架内设有截面为圆环形结构的第一支撑环，第一支撑环的外壁与第一骨架的内壁之间均匀设有八个第一支撑架。
上述一种人工石墨高导膜连续成卷的卷材，其中，所述第二骨架内设有截面为正八边形结构的第二支撑环，第二支撑环的外壁与第二骨架的内壁之间均匀设有八个第二支撑架。
上述一种人工石墨高导膜连续成卷的卷材，其中，所述人工石墨高导膜的骨架结构中填充高分子聚合物，所述高分子聚合物按重量份数计由环氧树脂50-70份、尼龙树脂5-7份、乙醇15-25份、纳米纤维0.8-3.4份、氧化铝1-7份和氧化锌1-5份混合而成。
本发明的有益效果为：
本发明利用电镀工艺把石墨镀在基体上，再用单面胶带把石墨层剥离下来，最后通过将石墨烯微片层粘附在弱粘保护膜上从而制成石墨烯卷料，石墨烯卷料；
本发明将成卷的石墨烯膜和静电膜通过压延机压合成卷，适合大量的及自动化生产，并能制作至少100米的长度，因此极大地提高了生产效率，通过膜切机即可精切切割，避免出现废品，减少了人工，降低了成本。
本发明的人工石墨高导膜的骨架结构第一骨架层、第二骨架和连接条结合形成，既提高了导热率，又增加了韧性和力学强度，提升了石墨膜卷材的整体性能。
