Abstract
本发明公开了一种锂电池软包装复合膜，其自外向内依次包括相互贴合的耐热高分子膜、粘合剂层、金属箔以及热塑性密封膜，所述粘合剂层是由下述的粘合剂组合物形成的：聚酯多元醇100份、环氧树脂1‑20份、固化剂1‑10份，所述聚酯多元醇的数均分子量为8000‑25000，酸值AV<1mgKOH/g，玻璃化转变温度Tg<20℃；所述环氧树脂的环氧值EEW＝100‑1000；所述固化剂为多官能团异氰酸酯型固化剂。本发明还公开了该锂电池软包装复合膜的制备方法、锂电池包装袋、锂电池及其应用。本发明的锂电池软包装复合膜，粘结强度好，在冲压加工时不易发生耐热膜和基材之间的分离、膜和基材的破裂漏光以及高温高湿下的分层问题。
Description
技术领域
本发明涉及锂电池外包装材料领域，具体涉及一种锂电池软包装复合膜，该复合膜的制备方法、由该复合膜制备的锂电池包装袋、锂电池及其应用。
背景技术
聚氨酯树脂是由多元醇类与聚异氰酸酯通过聚氨酯化反应得到，其中，多元醇类通常包括聚醚多元醇，聚酯多元醇，聚己内酯多元醇，聚碳酸酯多元醇，聚烯烃多元醇，聚丙烯酸多元醇等。聚氨酯树脂，因其独特的分子结构，而具有较高的内聚能以及可调的柔软度，与金属、木材、纤维、橡胶、塑料等极性表面存在极强的分子间相互作用，在涂装、包装、衣料服饰、电机、汽车及建筑等领域作为粘合剂被广泛应用。
作为包装用途的聚氨酯型粘合剂，一般用在诸如食品，药品等保管保存用袋状包装材料的制造和使用过程中。这类袋状包装材料，通常选用铝箔等金属箔与塑料高分子膜，通过粘合剂形成层状贴合型复合材料，该复合材料具有遮光隔热、耐热、阻隔气体以及耐受被包装物等特性。在新能源等产业领域，锂离子充电电池(以下简称锂电池)外包装材料选用上述的层状贴合型复合材料制成袋状软包装体，与通常的不锈钢壳、铝壳相比，因其具有小型化、轻量化、超薄化、成型加工容易等特点，得到了极大的关注。
软包装锂电池用铝塑复合膜，通常组成为：中间为铝箔基材(芯材)，外侧贴合聚酯/尼龙等耐热高分子膜，内侧贴合聚烯烃树脂构成的热塑性密封膜。铝箔基材作为芯材，起到防止水分/氧气的外部侵入及遮光作用。基于锂电池的安全性及长期使用寿命考量，铝塑复合膜必须满足耐电解液性、水汽阻隔性及耐湿热性等严格的指标。同时由于电池的短小轻薄以及有效利用空间体积的趋势，对铝塑复合膜的冷冲深加工要求愈发苛刻。
铝塑复合膜因其制造工艺的差别，大致可以分为热法路线和干法路线。热法路线是指热塑性密封膜通过熔融挤出流延工艺等与铝箔基材结合，干法路线是指采用粘合剂把铝箔基材与热塑性密封膜贴合起来。两者的共同之处在于，外侧的耐热高分子膜与铝箔基材之间都采用粘合剂贴合工艺。热法路线制得的铝塑复合膜，整体的耐电解液腐蚀性好，但是冷冲深成型加工不良，这主要取决于外层粘合剂的特性。而干法路线则整体的加工性能优异，但是耐电解液性能普遍不佳，需要开发特殊的层间粘合剂，特别是粘结铝箔基材和热塑性密封膜的内层粘合剂。
用于软包装锂电池的铝塑复合膜，因其独特的使用要求，当选用市售软包装用粘合剂时，其综合性能普遍不佳。在热法路线中主要表现为粘结强度不良、冲压加工时极易发生耐热膜和基材之间的分离、膜和基材的破裂漏光以及高温高湿下的分层问题等。
发明内容
本发明要解决的技术问题是提供一种锂电池软包装复合膜，该复合膜粘结强度好，在冲压加工时不易发生耐热膜和基材之间的分离、膜和基材的破裂漏光以及高温高湿下的分层问题，特别适用于热法路线制得的锂电池用软包装材料。
本发明的另一目的在于提供该锂电池软包装复合膜的制备方法。
本发明的又一目的在于提供一种包含该复合膜的锂电池包装袋、锂电池及其应用。
为了解决上述技术问题，本发明提供了一种锂电池软包装复合膜，自外向内依次包括相互贴合的耐热高分子膜、粘合剂层、金属箔以及热塑性密封膜。具体如下：
(1)粘合剂层
本发明中，粘合剂层是由粘合剂组合物配置成涂布液，涂布于金属箔上干燥后得到的，进而通过卷对卷工艺实现贴合。粘合剂层厚度以1～10微米为宜，优选为2～8微米。厚度低于1微米，粘接性不足，粘合剂层倾向于生成孔洞；厚度超过10微米，复合膜的成型性呈现恶化的趋势。
其中，该粘合剂组合物包括按重量份计的如下组分：
聚酯多元醇 100份
环氧树脂 1-20份
固化剂 1-10份；
本发明中，聚酯多元醇指的是由多元酸(Ⅰ)与多元醇(Ⅱ)经脱水缩合及酯交换反应得到的聚酯多元醇类聚合物，以及进一步的通过化学反应得到的改性聚酯多元醇类聚合物。其中，多元酸和多元醇的组成和摩尔百分比为：
(Ⅰ)芳香族二羧酸50-80％、脂肪族二羧酸20-50％；
(Ⅱ)乙二醇0-40％，其余为主链碳原子数3以上的脂肪族二元醇。
本发明中，上述摩尔百分比为发生反应的原料的摩尔百分比，而并不是原料添加量的摩尔百分比。
本发明中，同时加入芳香族二羧酸和脂肪族二羧酸，有利于提高得到的聚酯二元醇的加工性和粘结性能。
本发明中，芳香族二羧酸包括但不限于邻苯二甲酸，间苯二甲酸，对苯二甲酸，2，6-萘二甲酸，邻苯二甲酸酐等，优选为间苯二甲酸和对苯二甲酸。脂肪族二元酸包括但不限于乙二酸、1,3-丙二酸、1,4-丁二酸、1,5-戊二酸、1,6- 己二酸、1,7-庚二酸、1,8-辛二酸、1,9-壬二酸和1,10-癸二酸等，优选为1,6-己二酸、1,8-辛二酸和1,10-癸二酸。
本发明中，主链碳原子数3以上的脂肪族二元醇选自下述二元醇中的至少一种：
1,3-丙二醇、2-甲基-1,3-丙二醇、2,2-二甲基1,3-丙二醇、1,4-丁二醇、1,5- 戊二醇、3-甲基-1,5-戊二醇、1,6-己二醇、1,7-庚二醇、1,8-辛二醇、1,9-壬二醇、 1,10-癸二醇等小分子二醇；以及分子量为500以上的聚烯烃二醇/完全氢化的聚烯烃二醇。
本发明中，将反应的原料多元醇限定为二元醇，其原因是多元醇(三元醇或以上，如丙三醇，三乙醇胺，季戊四醇等)在反应过程中会发生交联反应，使产物的粘度上升，不利于反应的进行。
本发明中，加入乙二醇，有利于反应的进行。因为在反应的过程中，通过酯交换反应乙二醇被蒸出，促进了反应的进行，有利于提高产物的分子量。若不加入乙二醇，反应条件将会相当苛刻。若乙二醇的摩尔百分比大于40％，则会影响聚酯二元醇的水解性。
本发明中，多元酸和多元醇混合后，按通常工艺在高温下脱水缩合，即得到聚酯多元醇。为提高反应速率，可选用适当的催化剂，采用高温、真空等条件，通过酯交换反应提高分子量。所得的聚酯多元醇，其数均分子量8000～ 25000为宜，若数均分子量低于8000，则耐水解性不足，由其构成的粘合剂加工性能不佳；若数均分子量高于25000，则粘度过高，制造工艺复杂，易发生涂布不良问题。优选的数均分子量为10000～20000。酸值(AV)以2以下为宜，若酸值高于2，则聚酯多元醇树脂自身的耐水解性不足，优选的酸值小于1。其玻璃化转变温度(Tg)以20℃以下为宜，若大于20℃，树脂的硬度偏大，作为粘合剂加工性不良。
本发明中，环氧树脂的环氧值(EEW)为100～1000，若环氧值大于1000，则其分子量偏大，与主树脂(即聚酯多元醇)的相容性下降，粘结强度及耐候性不佳。优选的，环氧树脂选自双酚A型，双酚F型，双酚E型，氢化双酚A 型，氢化双酚F型，氢化双酚E型环氧树脂中的至少一种。进一步优选的，上述环氧树脂为双酚A型环氧树脂。
本发明中，固化剂为多官能团异氰酸酯型，其选自下述异氰酸酯类化合物的至少一种：1,6-六亚甲基二异氰酸酯(HDI)、异氟 尔酮二异氰酸酯(IPDI)、 2,4-二异氰酸酯基甲苯(TDI)、2,6-二异氰酸酯基甲苯、4,4-二苯基甲烷二异氰酸酯(MDI)、1,3-二苯甲基二异氰酸(XDI)等；以及以它们为原料得到的加成体、三聚体、缩二脲型聚异氰酸酯、脲基甲酸酯型聚异氰酸酯。除此之外，多官能团异氰酸酯型固化剂还可为多聚MDI，市售末端异氰酸酯型的预聚体，以及本发明的聚酯多元醇通过改性得到的末端异氰酸酯型预聚体等。
本发明中，固化剂还可为多官能团密胺型固化剂。
从反应性及供应难易考量，固化剂优选为HDI、IPDI的三聚体型，或TDI 的加成体型。
本发明的粘合剂组合物，必要时可以加入二氧化钛，二氧化硅，滑石粉，碳酸钙，硅藻土，硫酸钡等无机类添加剂；松香树脂，萜烯树脂，石油树脂等增粘树脂类；以及紫外吸收剂，紫外稳定剂，抗氧化剂，阻燃剂，滑剂，流平剂，消泡剂，分散剂，防沉降剂等。
本发明的粘合剂组合物，在使用时，可直接将聚酯多元醇树脂、环氧树脂与固化剂混合得到无溶剂型，也可以将聚酯多元醇树脂、环氧树脂与固化剂溶于有机溶剂得到溶液型。其中，有机溶剂应当选用对异氰酸酯具有低的反应活性或者不反应的有机溶剂，具体举例如下：丙酮，甲乙酮，甲基异丁基酮，环己酮等酮类；甲苯，二甲苯等芳香烃类；正己烷，正庚烷，环己烷等脂肪烃/ 脂环烃类；二恶烷，四氢呋喃等醚类；乙酸乙酯，乙酸丁酯，乙酸异丁酯等酯类；N，N-二甲基甲酰胺，N，N-二甲基乙酰胺，N-甲基吡咯烷酮等酰胺类等。优选的选用乙酸乙酯，乙酸丁酯等酯类。上述有机溶剂可单独使用，或者两种以上混合使用。配成溶剂型时，需要调整成适宜的固含量及粘度的溶液，作为涂布液用于卷对卷的涂布工艺中。其中，溶液的固含量以15～50％为宜，粘度以50～1000mPas为宜；若固含量过低或粘度过低，会导致使用大量的有机溶剂；若固含量过高或粘度过高，则导致粘结强度波动，涂布外观不良。
(2)耐热高分子膜
作为最外层，在锂电池外包装材中赋予成型性，同时在电池制造(热融合) 过程及使用过程中赋予耐热性及耐刺穿性能。本发明中的耐热高分子膜可选择市售的单层或者多层复合的耐热性高分子膜，比如聚酯膜、尼龙膜及聚酰亚胺膜等。优选的为聚酯膜或尼龙膜。其厚度以10～40微米为宜，优选的为15～ 25微米。
(3)金属箔
作为芯材赋予复合膜阻隔性及成型性，其既可以防止水气、氧气等侵入电池内部，又能够遮光防止电解液劣化，同时要满足加工成型性。金属箔以纯铝箔、铝-铁合金箔、铝-锰合金箔、铜箔、不锈钢箔等为宜，优选的为铝-铁合金箔。必要时，金属箔表面可选择市售铬酸液等做脱脂钝化处理，以提高耐腐蚀性及密着性。金属箔厚度以10～50微米为宜，优选为20～40微米。厚度过薄，轧制加工中形成的缺陷，表面针孔等过多，阻隔性不佳；厚度过厚，得到的电池其重量比能量不适宜。
(4)热塑性密封膜
热塑性密封膜通过熔融挤出流延工艺等与铝箔基材结合。作为最内层材料，其具有耐电解液性质以及热熔密封性。材料方面，以市售聚烯烃类薄膜为宜，如聚乙烯，聚丙烯，乙烯-丙烯-丁二烯共聚物等；厚度以30～100微米为宜，过薄，密封阻隔性不良；过厚则加工性不良。可采用热熔挤出的马来酸酐改性聚丙烯作为热熔粘合剂，贴合金属箔与上述聚烯烃类薄膜。或者采用马来酸酐改性聚丙烯粒子在金属箔表面直接流延热压成膜；或者采用马来酸酐改性聚丙烯膜，在金属箔表面直接热压贴合。
上述锂电池软包装复合膜可通过下述步骤制备而成：
首先制备金属箔/热塑性密封膜半成品，然后在金属箔的另一侧单面涂布本发明的粘合剂组合物溶液，干燥后与外层耐热高分子膜贴合得到最终成品。
或者，也可以先制备耐热高分子膜/粘合剂层/金属箔半成品，接下来，在金属箔的另一侧，采用用流延、熔融挤出贴合的方式复合热塑性密封膜，最终得到成品。
其中，涂布可采用滚涂、刮涂、喷涂等方式，涂布贴合过程，其烘干温度、贴合温度、贴合压力，依照材质等做适当调整。为完成交联固化反应，卷对卷复合后的最终成品需要经过适当的加热熟化处理为宜。熟化处理的温度为30～ 60℃，时间为3天～1周。
本发明还公开了上述锂电池软包装复合膜经模具冲压成型、侧面热封后得到的锂电池包装袋。该包装袋放入电芯后，注入电解液，顶部热封，从而完成了软包装锂电池的制造。该锂电池可用于数码电池、电动汽车及储能等领域。
本发明的有益效果在于：
本发明的粘合剂组合物，对金属箔，尼龙膜及聚酯膜等通用基材显示出良好的粘合性，且其耐溶剂性、耐湿热水解性、耐药品性以及成型加工特性优异。同时，由该粘合剂组合物经涂布、干燥及卷对卷复合工艺得到复合膜，特别适用于热法路线制得的锂电池软包装复合膜，该复合膜的粘结强度好，在冲压加工时不易发生耐热膜和基材之间的分离、膜和基材的破裂漏光以及高温高湿下的分层问题。该复合膜制备便利，可作为锂电池用包装材料。
