Description

耐热型UV减粘胶水及其在制备燃料电池中的应用
本公开要求于2022年08月08日提交中国专利局，申请号为202210941779.1，申请名称为“耐热型UV减粘胶水及其在制备燃料电池中的应用”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及一种耐热型UV减粘胶水及其在制备燃料电池中的应用。
背景技术
燃料电池的核心部件为MEA(Membrane Electrode Assembly)膜电极，也称之为七合一组件。七合一组件包括CCM(catalyst coated membrane，催化层/质子交换膜组件)、附着于CCM两侧的边框及气体扩散层。一般先在CCM的两侧贴合边框得到五合一组件，再在五合一组件的两侧贴合气体扩散层，即可得到七合一组件。CCM层包括PEM膜(即质子交换膜)以及PEM膜相对两侧的催化层。
发明内容
随着“双碳”目标牵引、国家政策支持、技术日趋成熟，对燃料电池产能要求越来越高，现有采用不同的设备分别对CCM进行分条 以及对边框进行冲切，再进行贴合的工艺渐渐无法满足工艺及产能迭代需求。
例如，CN112582654A公开了一种膜电极的制造方法，其制备工艺中采用的胶接剂将边框粘贴于托底膜层(转移膜料带)上以输送边框，后再分离托底膜层。
但本公开的发明人发现，使用上述工艺或类似工艺制备相关中间品时，在分离转移膜料带时，会不同程度地导致CCM的破损。
鉴于此，特提出本公开，提供一种耐热型UV减粘胶水及其在制备燃料电池中的应用，以克服上述问题。
本公开是这样实现的：

使用本公开提供的耐热型UV减粘胶水应用于燃料电池的制备工艺中，可以减少CCM的破损，提高产品合格率。

需要说明的是，在其他实施例的应用中，基材10并不限于电晕PET，本领域技术人员可以根据需要选择任意感兴趣的材质作为基材。
实施例2
本实施例的耐热型UV减粘膜与实施例1基本相同，不同的是原料配比，本实施例所用原料配比如下：
表2耐热型UV减粘胶水原料配比
实施例3
本实施例的耐热型UV减粘膜与实施例1基本相同，不同的是原料配比，本实施例所用原料配比如下：
表3耐热型UV减粘胶水原料配比
对比例1
配制耐热型UV减粘胶水：在500mL遮光杯中投入28g 1,6己二醇二丙烯酸酯、8g三羟甲基丙烷三丙烯酸酯、120g热塑性丙烯酸树脂和118g乙酸乙酯，用分散机搅拌均匀，然后再按次序边搅拌边添加1.9g光引发剂184和8.5g N75(20％浓度的乙酸乙酯稀释液)及0.32g GA-240(5％浓度的乙酸乙酯稀释液)，添加完后以500rpm的转速搅拌30min后，静置30min以上自然消泡，即可得到耐热型UV减粘胶组合物；
涂布减粘胶工艺：在电晕基材上涂布耐热型UV减粘胶，50号线棒刮涂，烘烤温度为95℃，烘烤时间为3min，形成均匀的UV减粘胶层，然后再在减粘胶层表面贴覆25μm的离型PET，即可得到耐热型UV减粘保护膜。
对比例2
涂PET底涂层：选用电晕PET，基材厚度50μm，底涂剂为聚碳酸酯改性的脂肪族水性聚氨酯树脂乳液50份，碳乙胺交联剂3份，去离子水10份，1000r/min转速搅拌，搅拌均匀后真空脱泡。刮涂至PET基材的电晕面，加热温度为90℃，烘干时间5min，烘干形成厚度为2μm的均匀涂层；
配制耐热型UV减粘胶水：在500mL遮光杯中投入30g脂肪族丙烯酸酯齐聚物、120g热塑性丙烯酸树脂和118g乙酸乙酯，用分散机搅拌均匀，然后再按次序边搅拌边添加1.9g光引发剂184和8.5g N75(20％浓度的乙酸乙酯稀释液)，添加完后以500rpm的转速搅拌30min后，静置30min以上自然消泡，即可得到耐热型UV减粘胶水；

实验例
测试实施例1-3，以及对比例1-2的耐热型UV减粘保护膜的性能，耐热型UV减粘保护膜与CCM粘贴测试方法：365nm波段LED灯照射30s减粘后，与CCM在120℃，2Mpa条件下，热压2min；结果见下表：
表4测试结果

可以看出对比例1和2的耐热型UV减粘保护膜UV后剥离后会导致CCM和PEM导致损坏；而使用实施例1-3的耐热型UV减粘保护膜UV后剥离后对CCM和PEM无损伤。
以上实施例和对比例的测试数据表明，在基材表面涂布底涂层，使之作为基材与UV减粘胶层的中间连接层，对基层的界面进行改性，底涂层与减粘胶层的结合力均较强，不受高温影响，可解决UV减粘胶在高温烘烤过程中与基材脱胶的问题。此外，从UV减粘胶水的原料组成来看，由于燃料电池的应用场景要求，汞灯引发条件易产生臭氧、高环境温度进而影响催化层以及膜电极的性能和寿命，引发剂应选择固定波段、能量低的引发条件的引发剂；上述实施例中的UV减粘胶水的原料组成中不含影响催化层电化学性能的官能团、离子，避免催化剂中毒或活性降低；采用多官能度低聚物或单体和复合交联体系，交联剂中大分子在烘干过程中发生交联固化，避免原料组分在交联过程中向表面跃迁；特定原料组成比例降低UV后的表面粘性，与极易脱落的催化层表面热压接触也不发生粘连；UV减粘胶水固化后的玻璃化温度大于130℃，保证与PEM的热压不粘连的效果，解决了热压工艺过程中的粘连问题；减粘胶UV的胶系主体结构中羟基低、羟值低，避免因结构中的羟基与PEM中磺酸基团发生反应而产生的粘连。

本实施例的七合一料带可以通过实施例6的五合一料带制备，通过对五合一料带进行UV减粘，剥离其中一侧的转移膜料带本体，然后贴合扩散层片料(GDL)，得到六合一料带，其中，扩散层片料通过转移膜料带本体传送，扩散层片料与转移膜料带本体通过如上实施例的耐热型UV减粘胶水粘合传送；接着再剥离另一侧的转移膜料带本体，再贴合扩散层片料，即可得到七合一料带。需要说明的是，相关的工艺制备步骤属于本领域的公知技术，本文不详细描述。
本公开实施例相对于现有技术的创造性在于使用上述实施例的耐热型UV减粘胶水进行粘合制备相应的电池原料组件，相对于现有技术，使用本公开实施例五合一料带或七合一料带通过UV减粘剥离转移膜料带本体时不会导致CCM和PEM损伤，大大地提高了下游产品如五合一组件、七合一组件等的合格率，由此原料制备的电池性能更好，良品率更高。
