Abstract
本发明的课题是提供对于主要用于包含高分子的涂料、墨液、粘接剂、锂离子电池的正极、负极、隔板等的涂覆液,能够形成表面平滑性优异的耐热变形性高的涂覆膜的组合物。解决手段是一种涂覆液组合物,其特征在于,包含填料、溶剂、分散剂、增稠剂,在涂覆于基材而形成了0.5~20μm的厚度的涂覆膜时,涂覆膜在170℃、15分钟加热前后的收缩率为15.0%以下。
Description
技术领域
本发明涉及包含填料、溶剂、分散剂和增稠剂的涂覆液组合物和包含本发明的涂覆液组合物的涂覆膜、带有涂覆膜的基材,涉及对于主要用于包含高分子的涂料、墨液、粘接剂、锂离子二次电池的正极、负极、隔板等的涂覆液,在施加了热时也不易变形的涂覆膜。
背景技术
从环境方面、安全方面的观点、效率性考虑,在全部工业领域广泛使用了:使用了组合物的涂覆、印刷技术。
然而,并未掌握有助于良好地保持了外观的涂覆膜形成的因素。
在专利文献1中,通过使将纤维状纤维素用离子交换水进行稀释而得的悬浮液为特定的TI值,从而提高电池用隔板涂液的分散性和涂覆容易性。然而,包含除纤维状纤维素和离子交换水以外的组合物的状态的TI值没有公开,此外关于有助于耐热性的因素,没有记载和暗示。
在专利文献2中公开了涂覆性优异,可以形成均匀的涂膜的涂液,但为涂液中的水溶性成分的含量为5质量%以下,固体成分多的状态的涂液。
在这些专利文献中,都必定对于耐热性、变形性这样的观点完全没有任何暗示。已知特别是在锂离子二次电池等被搭载于电动汽车等的情况下,如果在万一异常发热时超过涂覆膜所包含的多孔质聚烯烃膜的结晶熔点,则细孔径缩小而不通过锂离子,抑制进一步发热的情况是一般的,但在温度进一步上升了的情况下,在超过了隔板膜熔断而发生破裂的温度即熔化温度的情况下聚烯烃膜缩小,正极与负极短路而成为起火的原因。

[用途]
本实施方式的涂覆液组合物根据混配的填料的种类,可以用于涂料、墨液、粘接剂、锂离子电池的正极、负极、隔板等的各种涂覆液。
涂覆液组合物可以直接作为涂覆液而使用,但根据需要,可以适当用溶剂等调整浓度、粘度而作为涂覆液使用。

需要说明的是,所谓干式法,是在制造时不使用溶剂的干式工艺,可举出例如将熔融了的树脂进行采用T型模的熔融成型、注射成型等。此外,外层和内层可以为干式法,也可以为湿式法,湿式法是在使用添加/混合了添加物的树脂而制成了膜后,将添加物进行溶剂提取的方法。
关于基材的厚度,整体的厚度从与目的对应的机械强度、性能、小型化等方面考虑适当选择,优选为7.0μm以上,上限优选为50μm以下。如果为该范围的厚度,则强度高,也可以使离子传导性高。
此外在多孔质基材的情况下,其透气度优选为80s/100cc以上,上限优选为700s/100cc以下。如果具有该范围的透气度,则不易短路,离子的迁移率也高。
多孔质基材的孔隙率优选为30%以上,上限优选为70%以下。如果为该范围的孔隙率,则机械强度高,也不发生短路,也可以使离子的迁移率高。
多孔质基材的极大孔径优选为0.05μm以上,上限优选为2μm以下,如果在该范围,则在制成隔板时,离子的迁移性高,电阻也大幅地变低。
干燥方法没有特别限制,可举出旋转干燥、真空干燥、暖风干燥、红外线干燥等。干燥时间也没有特别限制。
在构成隔板的情况下,可以通过将上述涂覆液组合物涂布于上述基材表面的方法等来构成。

构成锂离子二次电池的构件可以大致分为正极电极、负极电极、隔板、电解液。正极电极和负极电极各自含有进行将电子送出接收的氧化/还原反应的活性物质。正极电极与负极电极可以以经由电池用隔板而叠层而得的叠层结构的电极组、进一步将其卷绕而得的卷绕结构的电极组的形态使用。

[实施例1~10、比较例1~7]
在200ml树脂容器中按照离子交换水、分散剂、粘合剂、增稠剂、填料的顺序计量表1记载的规定量,投入到自转公转型混炼机(シンキー社制ARE-250)。盖严,在混合(MIXING)60秒和脱泡(Deforming)60秒的条件下混合而获得了均匀的涂覆液组合物。
需要说明的是,分散剂、粘合剂、增稠剂为固体成分的质量份。
[表1]
关于所得的组合物,进行了以下评价。
<涂覆试验方法>
将所得的涂覆液组合物3.5g利用养护带固定于厚度16μm的聚丙烯片,进一步在涂覆机的涂覆台将聚丙烯片利用双面胶带进行固定(15cm×30cm:厚度0.1μm)而载置,使用棒式涂布机(ヨシミツ精機株式会社制宽度:50mm×厚度:5μm)利用自动涂覆机(テスター産業株式会社制Pi-1210)以200mm/秒的速度进行了涂覆。
然后,将涂覆了的聚丙烯片利用暖风干燥器在40℃的温度下干燥1小时,制作出涂覆膜。
<溶液粘度>
将涂覆液组合物的23℃下的粘度利用ブルックフィールド社制DV2T型粘度计转子SC4-28带有水套的少量样品适配器,以50rpm进行了评价。
<TI值>
TI值(触变指数)由以下式子算出。
TI值=0.1/s的低剪切速度下的粘度(Pa·s)÷10000/s的高剪切速度下的粘度(Pa·s)
使用AntonParr制旋转式粘度计(流变仪)测定。具体而言,对于23℃下的粘度,从剪切速度0.1秒-1到10000秒-1,经315秒一边提升速度一边测定,连续地从10000秒-1到0.1秒-1经315秒一边降低速度一边测定。将一边降低剪切速度一边测定时的测定值设为各剪切速度下的粘度,求出表2所示的剪切速度下的粘度的比率。
<涂覆膜厚度>
使用テクロック社制定压厚度测定仪PF-11J,按照JISK6400-1-2004,测定涂覆膜的中心和与中心上下相距10cm的2点共计3点,进行了加权平均。
<涂覆表面外观>
通过以下基准判定实施了涂覆膜的表面外观。
〇:在涂覆表面未确认到空隙。
△:在涂覆表面确认到10个以内空隙
×:在涂覆表面确认到超过10个空隙
<表面粗糙度>
使用滑动式的サートロニックデュオ表面粗糙度计(TAYLOR HOBSON社制),按照JISB0601-2013,对涂覆膜测定中心和与中心上下相距10cm的2点、共计3点的Ra并进行了平均。
<收缩率>
将涂覆膜的涂覆方向设为M方向,将与其垂直的方向设为T方向,以各边与M方向、T方向一致的方式切出了1cm见方的正方形样品后,加入到内温170℃的热空气箱,在大气下加热15分钟,关于M方向(涂覆了的方向)与T方向(相对于涂覆了的方向垂直的方向)各自,将相对于进行热处理前的长度(L),收缩到热处置后的长度(l)的比例以百分率表示。
各方向的收缩率(%)=(L-l)/L×100
将M方向、T方向的收缩率的算术平均设为收缩率。
[表2]
超出(over)为测定限度以上
根据表2判断,将规定的温度时间下的收缩率调整为15.0%以下的实施例的涂覆液组合物在涂覆膜的表面未确认到空隙,外观良好。此外实施例的涂覆膜的表面粗糙度Ra为2.41以下,获得了与大部分的比较例相比小的值。
