树脂基复合薄膜材料及其制备方法、太阳电池组件 技术领域
本发明涉及新能源发电和光伏应用领域，特别涉及一种树脂基复合薄膜材料及其制备方法、太阳电池组件。
背景技术
在当前社会，能源矛盾与环境问题越来越凸显，发展各类清洁能源是必然趋势。近年来，光伏行业快速发展，技术更新逐步加快，目前光伏行业正向产品多元化发展，高可靠性、高功率、低安装成本的各种功能组件研究开发已成为光伏组件发展的一种方向。
太阳能光伏发电依靠太阳电池把光能直接转变为电能。在过去的十年中，光伏电池全球总产量以平均超过40％的年增长率增加，至2012年底全球光伏发电系统装机容量已达100GW。预计光伏发电在2030年占到世界能源供给的10％，对世界的能源供给和能源结构做出实质性的贡献。
现有大规模制造的太阳电池组件如附图1所示，采用超白压花钢化玻璃作为支撑，使用乙烯和醋酸乙烯酯共聚物(EVA)，含氟的绝缘材料做背板在真空状态下热压密封为层压件4，封装完成后采用铝合金边框1镶边提供机械支撑，然后采用专用的金属支架完成安装，再利用连接器2实现太阳电池组件内的电气连接，并将连接器2与引线用的接线盒3相连。
作为光伏领域运用的封装材料，要求其具备抗紫外、抗老化等性能，现有光伏组件(太阳电池组件)的封装材料主要为光伏钢化玻璃、EVA、光伏背板，其中玻璃密度达2.5克/立方厘米(g/cm3)，常用3.2毫米(mm)玻璃每平方米重量达8公斤(Kg)，由其封装完成的光伏组件(太阳电池组件采用钢化玻璃封装)通常质量较大，其重量每平方米达到10公斤以上，加上安装支撑结构，每平方米至少达到12公斤以上，当其应用在建筑物顶部或墙面等场合中，对光伏组件的支撑结构提出了较高的要求，增加了工程建设、安装的成本。在建筑及家庭屋顶安装过程中，存在重量重，安装劳动强度大，实施 困难；有些场合由于建筑承重载荷的限制不能安装；产品外观单一，不太容易变化以适应不同建筑美观的要求等缺点。
目前也有一些技术方案提出通过改变封装材料解决光伏组件轻量化的问题，以高透过薄膜、透明背板替代钢化玻璃，但是在实际应用过程中，封装大多仅采用EVA、POE等胶膜，如此封装后的光伏组件，在抗冲击、防火等性能无法满足光伏行业技术标准。
发明内容

为解决上述问题，本发明技术方案还提供一种上述树脂基复合薄膜材料的制备方法，包括：将所述树脂与固化剂预混后，先通过涂覆装置均匀地涂覆在所述纤维布上，再通过加压加热使所述树脂与固化剂的混合物与所述纤维布进行预粘合过程，最后分段裁切制得合适尺寸的所述树脂基复合薄膜材料。
可选的，所述预粘合过程的加压范围在0.05～0.25千帕(Kpa)。
可选的，所述预粘合过程的加热温度范围在90～130摄氏度(℃)，加热时间在5～20秒。
为解决上述问题，本发明技术方案还提供一种太阳电池组件，包括：层压件、连接器和引线用的接线盒；所述层压件包括依次叠合的氟塑料薄膜、第一树脂基复合薄膜、第一EVA、太阳电池、第二树脂基复合薄膜和背板；所述连接器与所述接线盒相连，用于所述太阳电池组件内的电气连接；所述第一树脂基复合薄膜和第二树脂基复合薄膜采用上述的树脂基复合薄膜材料。

具体实施方式
如背景技术所述，现有的光伏组件(太阳电池组件)由于采用了钢化玻璃封装，导致在建筑及家庭屋顶安装过程中，存在重量重、安装劳动强度大、可能因建筑承重载荷的限制而不能安装、难以适应不同建筑的安装要求等缺点。如图2所示，现有技术中太阳电池组件的层压件是通过依次将超白钢化压花玻璃21、EVA膜22、太阳电池串23、EVA膜24以及背板25叠合而成 的。
针对光伏组件常用封装材料(钢化玻璃)重量较重的问题，虽然现有技术中也存在一些技术方案通过改变封装材料解决光伏组件轻量化的问题，然而这些方案中所使用的封装材料却又无法满足抗紫外、抗老化、抗冲击、防火等光伏行业技术标准。
为解决上述问题，本发明技术方案提供一种新型的主要应用于光伏封装的复合材料，具体涉及一种轻质树脂基复合薄膜材料及其制备方法。
如图3所示，所述树脂基复合薄膜材料的制备方法包括：
步骤S301，将树脂与固化剂预混；
步骤S302，以涂覆装置把预混后形成的混合物均匀地涂覆在由纤维类材料制成的纤维布上；
步骤S303，通过加压加热使所述树脂与固化剂的混合物与所述纤维布进行预粘合；
步骤S304，分段裁切制得合适尺寸的树脂基复合薄膜材料，所述树脂基复合薄膜材料组份的重量百分比为：纤维类材料30％～50％，树脂35％～50％，固化剂15～20％。
此外，本发明技术方案还涉及太阳电池组件的设计及制造技术，具体提供一种新型轻质量的太阳电池组件的设计及制造方法。
所述太阳电池组件及其制造方法的目的如下：①减轻产品的重量，使产品能够在更多的场合安装；②实现产品尺寸及颜色的任意改变以适应建筑美观的要求；③降低产品安装时的劳动强度以及提高安装的便利度，从总体上降低安装成本。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例作详细的说明。
本实施例提供的树脂基复合薄膜材料由纤维类材料、树脂和固化剂组成，所述树脂与固化剂的混合物均匀涂覆于由所述纤维类材料制成的纤维布上；所述树脂基复合薄膜材料组份的重量百分比为：纤维类材料30％～50％；树脂 35％～50％；固化剂15～20％。
在实际实施时，所述树脂基复合薄膜材料组份的重量百分比具体可以按照以下几种方式之一进行组配：
(1)纤维类材料30％、树脂50％、固化剂20％；
(2)纤维类材料40％、树脂40％、固化剂20％；
(3)纤维类材料40％、树脂45％、固化剂15％；
(4)纤维类材料40％、树脂45％、固化剂15％；
(5)纤维类材料50％、树脂35％、固化剂15％。
需要说明的是，以上仅举例说明所述树脂基复合薄膜材料组份的重量百分比，本领域技术人员可以根据实际情况按范围配置合理的组份构成。
作为一优选的实施例，所述纤维类材料可以为玻璃纤维、碳纤维或芳纶纤维，且选用的纤维类材料应当具有良好的绝缘及耐候性，单丝直径在3～23μm之间，例如选取单丝直径为3μm、13μm或23μm的纤维类材料。
实际实施时，所述纤维布可以采用平纹、斜纹、缎纹、罗纹或席纹中的一种或一种以上织造方式制成，其单位面积重量可以在30克/平方米～400克/平方米之间，可以根据需要选用合适重量的纤维布，例如选取单位面积重量是30克/平方米、100克/平方米、200克/平方米、300克/平方米或400克/平方米。
本实施例中，所述树脂可以由羟基聚酯树脂、环氧树脂、丙烯酸树脂、聚氨酯树脂、氟碳树脂中的一种或者一种以上按照任意配比混合而成。
本实施例中，所述固化剂可以由异氰脲酸三缩水甘油酯(TGIC)、异氰脲酸三－β－甲基缩水甘油酯、甲基丙烯酸缩水甘油酯、羟烷基酰胺、异氰酸酯、邻苯二甲酸酐、偏苯三酸酐、十二碳二酸、双氰胺、二酰肼中的一种或一种以上任意配比混合组成。
作为一优选的实施例，通过涂覆装置将所述树脂与固化剂预混后形成的混合物均匀涂覆在所述纤维布上后，所述树脂与固化剂的混合物在所述纤维布上的重量范围可以在30克/平方米～400克/平方米之间，例如为30克/平方 米、100克/平方米、200克/平方米、300克/平方米或400克/平方米。
本实施例提供的上述树脂基薄膜复合材料可以作为新型太阳电池组件所使用到的关键材料，该材料由纤维类材料作为基体材料，在纤维类材料上复合树脂材料，在一定温度、压力情况下进行熔融复合，以满足后续制备太阳电池组件过程中涉及的相关层压工艺的要求。
所述树脂基薄膜复合材料的制备工艺如图4所示，主要包括进料、涂覆、热熔复合、分切和包装这几个步骤。为了实现所述树脂基薄膜复合材料的制备工艺，所使用到的主要设备如图5所示。图5示出了纤维进料机51、涂覆机器52和热熔复合机53，分别对应进料、涂覆、热熔复合的工艺过程。在实际实施时，将由纤维类材料织造制成的纤维布放入纤维进料机51，将经过预混所形成的树脂与固化剂的混合物，通过涂覆装置52均匀地涂覆在纤维进料机51所输出的纤维布上，然后通过热熔复合机53加压加热使树脂与固化剂的混合物与纤维布进行预粘合过程，最后分段裁切制得合适尺寸的树脂基薄膜复合材料(可以作为光伏组件的封装材料)，并对制得的树脂基薄膜复合材料进行包装处理。由于所述分切和包装的工艺为本领域技术人员所知晓，此处不再详细描述。
需要说明的是，在本实施例中，所述预粘合过程需采用特定的加压、加热控制，因为只有在合适的压力和温度情况下，才能使树脂与固化剂的混合物与纤维布之间较好地完成热熔复合过程，确保满足制备太阳电池组件过程中的层压工艺的要求，从而形成真正能适用于太阳电池组件的封装材料。
本实施例中，所述预粘合过程的加压范围在0.05～0.25Kpa，例如为0.05Kpa、0.1Kpa、0.2Kpa或0.25Kpa；所述预粘合过程的加热温度范围为90～130摄氏度(℃)，例如为90℃、100℃、110℃、120℃或130℃；所述预粘合过程的加热时间范围为5～20秒，例如5秒、10秒、15秒或20秒。
此外，在其他实施例中，所述涂覆装置也可以为一撒粉头，此时所述涂覆装置是以撒粉的形式实现涂覆过程，将树脂与固化剂的粉状混合物涂覆于所述纤维布。
本实施例提供的树脂基薄膜复合材料的制备方法的具体实施还可以参考 上述树脂基薄膜复合材料的实施过程，此处不再赘述。
需要指出的是，虽然本实施例中的树脂基薄膜复合材料应用于太阳电池组件的封装材料能够取得较佳的实施效果，但光伏应用领域并非该树脂基薄膜复合材料的唯一应用领域，基于所述树脂基薄膜复合材料所具备的特性，本领域技术人员也能够将其应用在其他合适的领域中。
基于上述树脂基薄膜复合材料，本发明实施例还提供一种太阳电池组件。如图6所示，所述太阳电池组件包括：层压件34、连接器31、引线用的接线盒32、加强筋33和自攻螺钉35；所述连接器31与所述接线盒32相连，用于所述太阳电池组件内的电气连接；所述加强筋33为所述层压件34提供机械支撑；所述自攻螺钉35将所述层压件34与所述加强筋33之间进行固定；结合图7，所述层压件34包括依次叠合的氟塑料薄膜41、第一树脂基复合薄膜42、第一EVA43、太阳电池44、第二EVA45、第二树脂基复合薄膜46和背板47；本实施例中，所述第一树脂基复合薄膜42和第二树脂基复合薄膜46均采用上述树脂基复合薄膜材料。
需要说明的是，在其他实施例中，所述第二EVA45也可以不使用，而直接将太阳电池44与第二树脂基复合薄膜46进行叠合。
本实施例中，将上述树脂基复合薄膜材料应用为太阳电池组件(光伏组件)的封装材料，既能够解决光伏组件轻量化的问题，又能够满足抗紫外、抗老化、抗冲击、防火等光伏行业技术标准，而且经过实验表明，其也能满足光伏行业相关室外性能测试标准。
现有技术中常规的太阳电池组件的层压件与本发明实施例提供的太阳电池组件的层压件之间最大的不同在于：本发明实施例中使用了氟塑料薄膜以及树脂基复合薄膜材料替代了钢化玻璃给太阳电池组件提供一定的刚性从而保护太阳电池，如此不但能够大大减轻太阳电池组件的重量，由此适应更多场合的太阳能光伏发电产品的安装，而且还能降低产品安装时的劳动强度以及提高安装的便利度，从总体上降低安装成本。
此外，在本实施例中，所述第一树脂基复合薄膜42和第二树脂基复合薄膜46可以根据需要裁切或采用不同颜色的树脂进行复合而成，如此能实现太 阳电池组件产品尺寸及颜色的任意改变以适应不同建筑的安装要求。
从太阳电池组件结构上看，传统的太阳电池组件与本发明实施例提供的太阳电池组件之间的区别之一在于铝合金边框的不同。现有技术中太阳电池组件使用传统的铝合金边框为边缘卡接结构，如图8所示，需要将层压件嵌入铝合金边框中并使用硅胶粘接；而本发明实施例的太阳电池组件则使用简单铝合金边框，即：并非是常用的边缘卡接结构，而是采用加强筋的方式予以实现，如图9所示。实际实施时，图6所示的加强筋33具体可以是给板状的层压件34提供机械支撑的铝合金加强筋。本实施例中，所述加强筋33与所述层压件34之间先通过双面胶带粘接，然后再采用自攻螺丝35对两者进行机械固定。
当然，在其他实施例中，当应用上述树脂基复合薄膜材料作为太阳电池组件的封装材料时，也可以通过现有技术中常用的简单铝合金边框为所述层压件提供机械支撑。
需要指出的是，本实施例中将为所述层压件提供机械支撑的支撑部件(例如加强筋、铝合金边框等)以及将该支撑部件与所述层压件进行固定的固定部件(例如自攻螺丝)作为太阳电池组件的组成部分，在其他实施例中，所述支撑部件和固定部件也可以不作为太阳电池组件的组成部分，太阳电池组件仅包含层压件、连接器和引线用的接线盒，即太阳电池组件可以不含边框。
由于本发明实施例中太阳电池组件的层压件采用氟塑料薄膜以及树脂基复合材料替代钢化玻璃，由此减轻了太阳电池组件的重量，如此使得采用简单铝合金边框(加强筋)便能固定层压件成为可能，简单铝合金边框的采用进一步使本发明实施例中太阳电池组件的重量减轻。
传统的太阳电池组件与本发明实施例提供的太阳电池组件之间的区别还在于所采用的电缆连接器的不同。现有技术中常规的太阳电池组件采用标准快速电气连接接头，成本高，而本发明实施例中使用的连接器如图10所示，采用压接端子72以及热缩套管73，位于两端的电缆线71和电缆线74卡接入所述压接端子72，所述热缩套管73包围压接端子72，如此能够使电气连接可靠，成本低廉。
本发明实施例提供的轻质太阳电池组件与使用传统钢化玻璃的太阳电池组件相比，重量能减轻50％左右。
基于上述太阳电池组件，本发明实施例还提供一种上述太阳电池组件的制造方法，包括：将所述氟塑料薄膜、第一树脂基复合薄膜、第一EVA、太阳电池、第二EVA(可选用)、第二树脂基复合薄膜和背板依次叠合，并经层压工序形成所述层压件；对形成的所述层压件执行边缘裁切工序；粘接所述层压件与所述加强筋；以所述自攻螺钉将完成粘接的所述层压件与所述加强筋之间进行固定。
本发明实施例中的轻质太阳电池组件的制造工艺流程如图11所示，所述轻质太阳电池组件的制造工艺与现有技术的常规工艺之间的主要不同在于以下几个方面：
A)层叠工序
传统的层叠工序采用钢化玻璃做基板，然后依次叠放EVA、太阳电池、EVA、背板；而本发明实施例中的层叠工序则依次叠放氟塑料薄膜、树脂基复合薄膜材料、EVA、太阳电池、树脂基复合薄膜材料及背板。
B)层压工序
由于需要将树脂材料充分熔化粘接，层压的温度与传统太阳电池组件固化EVA相比要高，层压的时间也相对比较长。具体地，本发明实施例中的层压工序的层压温度较传统太阳电池组件层压温度高5～25℃，层压的时间较传统太阳电池组件层压时间长5～15分钟。由于传统太阳电池组件的层压温度以及层压时间为本领域技术人员所知晓，此处不再详细描述。
C)边缘裁切
本发明实施例中的边缘裁切工序采用机械或者激光的方式对形成的所述层压件的边缘进行切割，由于产品层压完成后机械强度比较高，且形成一个整体，因此需要采用机械或者激光进行切割，而传统的去边则沿着钢化玻璃边缘使用美工刀即可切除。
D)粘加强筋
本发明实施例中，使用双面胶带将方形铝合金型材(加强筋)粘接到层压件背面，而现有技术中常规的太阳电池组件则使用硅胶打入铝合金型材中，再与由钢化玻璃组成的层压件进行粘接。
E)安装自攻螺钉
本发明实施例中，在将层压件与铝合金型材(加强筋)粘接好后，使用自攻螺钉从正面固定，而现有技术中常规的太阳电池组件则不需要此工序，但是常规太阳电池组件需要使用装框机压合装框。
除了上述工艺步骤之外，本发明实施例中轻质太阳电池组件的制造工艺流程中涉及的其他工艺步骤可以参阅图11，由于所述其他工艺步骤为本领域技术人员所知晓，完全能够采用惯用的技术手段予以实现，此处不再详细描述。
本发明虽然已以较佳实施例公开如上，但其并不是用来限定本发明，任何本领域技术人员在不脱离本发明的精神和范围内，都可以利用上述揭示的方法和技术内容对本发明技术方案做出可能的变动和修改，因此，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化及修饰，均属于本发明技术方案的保护范围。
