Description
技术领域
本发明属于电池技术领域，具体涉及一种可常温储存的气凝胶封装胶膜及其制备和应用。
背景技术
随着全球节能减排要求的不断升级，新能源汽车所占市场份额逐渐提高。目前，新能源汽车动力系统主要来源的锂离子电池，经过多年的发展，已经得到显著的提高，但在条件下，仍然存在爆燃风险，电池“热失控”引发电动汽车起火和爆炸的事故屡见不鲜。
气凝胶隔热片是一种分散介质为气体的多孔性固体材料，具有导热系数低、保温效果好、A级防火、质量轻等特点。近年来，动力电池用隔热材料气凝胶材料开始应用在动力电池防火保温领域。被认为是目前可应用于新能源汽车动力电池用隔热材料及动力电池薄的保温隔热材料。在电芯出现热失控的情况下可有效抑止热扩散，另一方面，有效降低低温环境电池性能衰减，同时为有限的电池包节省更多空间。气凝胶隔热垫作为电芯之间的动力电池用隔热材料，以降低新能源汽车燃烧风险，提高驾驶性。
气凝胶隔热垫是由气凝胶隔热片与两片封装胶膜复合后的产品，为了防止气凝胶隔热片在汽车运行过程中脱落或掉粉，保证气凝胶隔热片在电池包中的使用寿命且保证气凝胶装配过程安全性。要求封装胶膜不仅具备优异的阻燃性能，同时具有较高的粘结力和机械性能，以及具有一定的耐温性。
现有技术中，常采用环氧类胶粘剂作为封装胶膜的胶层。环氧树脂是指分子中含有两个或两个以上环氧基团的一类高分子化合物，可与胺、咪唑、酸酐、酚醛树脂等各类固化剂配合使用形成三维网状固化物。环氧类胶粘剂主要由环氧树脂和固化剂两大部分组成。为改善某些性能，满足不同用途还可以加入增韧剂等助剂。由于环氧胶粘剂的粘接强度高、通用性强，在汽车、机械、化工以及日常生活等领域得到广泛的应用。
环氧胶粘剂储存的关键要求主要有两点，一是密封储存，二是低温储存。为什么需要低温密封储存呢？这与环氧胶粘剂成分中的固化剂有直接的关系。固化剂在胶粘剂产品应用过程起到非常重要的作用，如果固化剂受到污染或其它影响，均会导致产品使用异常。环氧胶粘剂固化剂为胺类固化剂，密封存储目的是防止与空气中的湿气或水气接触发生反应；低温存储目的是维持固化剂的稳定性，因为高温下，固化剂容易挥发出胺类气体，降低固化剂的活性，所以环氧粘接胶存储条件要特别注意。相对于热固性丙烯酸树脂，环氧胶黏剂的储存问题对厂商的生产能耗、操作方便性以及生产成本造成一定程度的冲击与影响。
因此，需要提供一种能够常温储存的的封装胶膜，以降低能耗和成本。

结果分析
对实施例1～6和对比例1～2中的气凝胶封装胶膜进行热压后剥离力、初始剥离力(未热压)、动态剪切强度和阻燃等级检测，其结果如表1所示。
其中，各检测标准和设备如下：
热压后剥离力：参照GB/T2792-1998标准，测试设备为科健KJ-1065A拉力机，其中，热压温度为100～130℃，热压压力为1～5Mpa，热压时间为15～20s；
初始剥离力(未热压)：参照GB/T2792-1998标准，测试设备为科健KJ-1065A拉力机；
动态剪切强度：参照GB/T7124-2008标准，测试设备为科健KJ-1065A拉力机；
阻燃等级；参照UL94塑料制品阻燃标准。
表1
结果显示，本发明实施例热压后剥离力均属于较高水平，同时剪切强度高，达到了VTM-0阻燃等级。
综上，本发明胶层采用热固性丙烯酸酯类压敏胶，通过设计高玻璃化转变温度的单体聚合、高交联度胶水的配方设计，及添加一定量的增粘树脂以及特定助剂，如阻燃剂、抗氧剂、塑化剂中的一种或多种，确保具有较强的粘结性，阻燃性以及耐老化性能。
显然，上述实施例仅仅是为清楚地说明所作的举例，并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引申出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
