Description
技术领域
本发明涉及太阳能电池密封材料用乙烯-醋酸乙烯共聚物(ethylene-vinylacetate copolymer,EVA)薄片的制备装置,更详细地涉及通过均匀排列热粘附性树脂来熔敷的方法制备EVA薄片的太阳能电池密封材料用EVA薄片制备装置。
背景技术
近来,从依赖以往化石燃料的发展,以清洁、生态能源的源泉使太阳光直接转换为电能的太阳能电池备受关注。特别是,在建筑物的屋顶部分等室外使用太阳能电池的情况下,一般以太阳能电池模块的形态使用。
此时,使用的太阳能电池用EVA薄片大部分以挤压或压延方法制备,然而这在调节薄片的厚度方面存在困难,且在EVA薄片内残留热史(Thermal History),从而在以后的太阳能电池的模块化过程中引发纵向(MD,Machine Direction)的热收缩。并且,由于致密的结构,在除去气泡方面存在困难,因而具有加长模块化工序时间的问题。
为了解决上述问题,日本特许公开公报第2002-363507号提供热收缩率小的热粘附性薄片,并记载有如下制备方法,其特征在于,利用撒布机在离型纸上撒布热粘附性树脂粉末来加热,使一部分或者整体粉末熔敷,冷却后剥离离型纸。
发明内容
本发明要解决的技术问题
本发明的目的在于,提供使热粘附性树脂粉末以均匀的厚度撒布且能制备厚度均匀的EVA薄片的太阳能电池密封材料用薄片制备装置。
技术方案
本发明提供太阳能电池密封材料用EVA薄片的制备装置,其包括:粉末供给部,在粉末供给部的内部具有用于收容热粘附性树脂粉末的桶形状,在粉末供给部的下部具有排出口;以及粉末排列辊,表面具有用于收容热粘附性树脂粉末的凹槽图案,以封闭上述排出口的方式配置。
此时,优选地,均匀分布上述粉末排列辊的凹槽图案。
而且,上述粉末供给部具有多个排出口,各个排出口能配置粉末排列辊。
而且,本发明提供太阳能电池密封材料用EVA薄片的制备装置,其包括:粉末供给部,在粉末供给部的内部具有用于收容热粘附性树脂粉末的桶形状,在粉末供给部的下部具有排出口;粉末排列辊,在表面具有用于收容热粘附性树脂粉末的凹槽图案,以封闭上述排出口的方式配置;循环带,通过上述粉末排列辊的下部而循环;加热部,对涂敷在上述循环带上的热粘附性树脂粉末进行加热熔敷;以及剥离辊(peel off roll),设在上述加热部的后端,从上述循环带分离以膜状态熔敷的热粘附性树脂粉末薄片。
此时,还包括卷绕辊,上述卷绕辊对通过上述剥离辊分离的热粘附性树脂膜进行卷绕。
并且,优选地,上述粉末排列辊沿着与上述循环带相反的方向旋转。

具体实施方式
参照以下说明的实施例,就能够明确本发明的优点和特征及其实现这些优点和特征的方法。但是本发明并不限于下面所公开的一些实施例,而能够通过互不相同的各种方式来实现,本实施例仅仅是为了使本发明的公开更完整并向本发明所属技术领域的普通技术人员准确告知发明的范畴而提供的,本发明仅根据发明要求保护范围的范畴而定义。在说明书全文中相同的附图标记表示相同的结构要素。
图1是表示本发明实施例的太阳能电池密封材料用EVA薄片制备装置的结构图,图2是表示本发明实施例的太阳能电池密封材料用EVA薄片制备装置的粉末排列辊部分的立体图。
根据本发明的太阳能电池密封材料用EVA薄片制备装置是为了均匀分配(涂敷)热粘附性树脂粉末后,加热以膜状态熔敷而制备EVA薄片。
热粘附性树脂粉末(EVA微粒粉末)具有借助EVA主链(backbone)的醋酸基来吸湿的性质,所以不容易以规定厚度涂敷。
本发明是为了利用粉末排列辊均匀涂敷热粘附性树脂粉末后,制备EVA薄片。
在此,热粘附性树脂粉末表示通过加热来表现粘附性的树脂粉末。作为上述乙烯类树脂,具体地可列举聚乙烯、乙烯-氯乙烯共聚物、乙烯-醋酸乙烯酯共聚物、乙烯-乙烯醇共聚物等。乙烯类树脂是乙烯及与乙烯能共聚合的树脂的共聚物,例如,如下。
除了乙烯与醋酸乙烯酯或丙酸乙烯酯等乙烯基酯的共聚物;乙烯与乙烯和丙烯酸甲酯、丙烯酸乙酯、丙烯酸异丁酯、丙烯酸n丁酯、甲基丙烯酸甲酯等不饱和碳酸酯的共聚物;乙烯与丙烯酸、甲基丙烯酸等不饱和碳酸酯的共聚物;或乙烯与不饱和碳酸酯的一部分被钠、锌、锂等金属盐中和的单体、丙烯、1-丁烯、1-己烯、1-辛烯、4-甲基、1-戊烯等σ-烯烃的共聚物等以外,这些共聚物的两种以上混合物等符合于此。
优选地可使用乙烯醋酸乙烯酯共聚物,这时的物性根据中和度和共聚物乙烯含量而决定。分子量越大,坚韧性和增塑性、耐应力开裂性、耐冲击性越得到提高,而成形性或表面光泽下降。另一方面,若共聚物乙烯含量增加,则密度和橡胶弹性、柔软性不同的其他聚合物或增塑剂之间的相容性提高而使软化温度下降。
并且,上述乙烯类树脂包含聚乙烯类树脂,但并不是特别限制的,其均可包含乙烯的单独聚合物,或者在聚乙烯接枝聚合乙烯基硅烷化合物的共聚物等。更具体地,上述乙烯类树脂中,共聚物乙烯含量优选为60%重量以上且小于90%重量。更优选地,乙烯含量可能在于65%重量以上且75%重量以下的范围。
此时,根据需要还可包含交联剂、交联助剂、防紫外线剂等,通过添加添加剂,从而能够使挤压中空成形中基材的变色、紫外线及模块化引起的变形最小化。
上述添加剂包含交联剂或防紫外线剂等,但根据需要还可添加其他各种添加剂。具体地,上述添加剂可列举硅烷偶联剂、润滑剂、抗氧化剂、阻燃剂、防变色剂等。
在乙烯类树脂中,若上述共聚物乙烯含量小于60重量%,则共聚物的粘附性变强而致使粉末的取出变难。如果即使得到了粉末,该粉末的流动性变差,结果粉末的均匀分散变难。若均匀的分散变难,则不能得到均匀的密封材料用薄片。在此不均匀的密封材料用薄片是指部分树脂的空隙率不同或薄片的厚度根据位置而不均匀的情况。并且,由于共聚物的粘附性变强,因而制备密封材料用薄片时,存在粘附在作为工序设备的辊或模具等的问题,由此除膜工序上可能发生困难。并且,若上述共聚物的乙烯含量超过90%重量,则透明性及柔软性变差,导致不能优选地用作太阳能电池的密封材料用EVA薄片。
并且,热粘附性树脂粉末的平均粒子大小优选为30目~100目范围。此时,热粘附性树脂粉末通过机械粉碎、冷冻粉碎、化学粉碎等来获得上述热粘附性树脂粉末。在上述热粘附性树脂粉末的粒子大小小于30目的情况下,因粉末非常微小而引起微粒子飞散的现象或难以调节EVA薄片的厚度或体积,在上述热粘附性树脂粉末的粒子大小大于100目的情况下,粉末的流动性变差,难以制备厚度均匀的EVA薄片。
如图所示,本发明的太阳能电池密封材料用EVA薄片制备装置,包括:粉末供给部110,在粉末供给部110的内部具有用于收容热粘附性树脂粉末的桶形状,在粉末供给部110的下部具有排出口;粉末排列辊120,表面具有用于收容热粘附性树脂粉末的凹槽图案,以封闭上述排出口的方式配置;循环带130,通过上述粉末排列辊的下部而循环;加热部140,对涂敷在上述循环带130上的热粘附性树脂粉末进行加热熔敷;剥离辊150,设在上述加热部140的后端,从上述循环带分离以膜状态熔敷的热粘附性树脂粉末薄片;卷绕辊160,对通过上述剥离辊150分离的热粘附性树脂膜进行卷绕。
上述粉末排列辊120在表面具有凹槽图案,通过上述粉末供给部110,在上述凹槽图案装满热粘附性树脂粉末。此后,若粉末排列辊120旋转而使凹槽图案朝向下部,则热粘附性树脂粉末从粉末排列辊脱离而涂敷在循环带130上。
这时,优选地,粉末排列辊120和循环带130互相以相反方向旋转。若它们互相以相反方向旋转,则从粉末排列辊120脱落的热粘附性树脂粉末对上述循环带130具有更高的相对速度,由此热粘附性树脂粉末的分布变的更均匀。
涂敷在循环带130上的热粘附性树脂粉末由加热部140加热而熔敷。
基于加热部140的上述热粘附性树脂粉末的固化,优选在70~110℃的温度下实现。
在固化温度小于70℃的情况下,上述热粘附性树脂粉末的一部分有可能熔敷的不充分,因此超过适合于太阳能电池密封材料用薄片的柔软性,难以制备太阳能电池模块。
相反,在上述固化温度大于110℃的情况下,由于固化温度太高,因而接近整体上述树脂粉末的量被熔敷而导致无法获得适合于密封材料用薄片的柔软性的问题,并且发生薄片附着在循环带130的制备方面的问题。
由热粘附性树脂粉末熔敷形成的热粘附性树脂膜通过剥离辊150,从循环带130分离,缠绕在卷绕辊160。
图示的实施例中,粉末供给部110具有一个排出口,并具有与一个粉末排列辊120相连接的形态,但上述粉末供给部具有多个排出口,在各个排出口还能配置粉末排列辊。
并且,还可具有与一个或多个粉末排列辊120相连接的多个粉末供给部110。
这样的情况下,可通过增加粉末的供给量来提高工序效率。
图3是表示本发明再一实施例的太阳能电池密封材料用EVA薄片制备装置的结构图。
本实施例的特征在于,在粉末排列辊120的流入侧还包括刷子170。在此,所谓粉末排列辊120的流入侧是指粉末排列辊120通过循环带130上侧之后流入到粉末供给部110的部分。
刷子部170执行用于除去从粉末排列辊120未被脱落的热粘附性树脂粉末的作用。刷子部170是为了从粉末排列辊120除去未被离心力和自重脱落的热粘附性树脂粉末的,这是因为当这些热粘附性树脂粉末未被除去的情况下,因持续的吸附而对通过凹槽图案涂敷的热粘附性树脂粉末的体积有影响。
图4是表示本发明又一实施例的太阳能电池密封材料用EVA薄片制备装置的结构图。
本实施例的特征在于,代替图3的实施例的刷子部170来包括压缩气体喷射部180。
压缩气体喷射部180向粉末排列辊120喷射压缩气体,从而除去未被脱落的热粘附性树脂粉末。
为了使收容在粉末排列辊120的凹槽的热粘附性树脂粉末顺利地向循环带130脱落,可利用振动单元,对粉末排列辊120施加振动。振动单元可以在粉末排列辊120的内部或外部。
并且,为了使热粘附性树脂粉末顺利脱落,还可用特氟龙(Teflon)等涂敷粉末排列辊120的表面。
以下,观察利用本发明的太阳能电池密封材料用EVA薄片制备装置来调节EVA薄片的厚度的情况。
例如,在粉末排列辊具有每一个体积为5mm3的1420个凹槽图案的情况下,设在粉末排列辊的凹槽图案的整个体积为7100mm3。
这时,若粉末排列辊的转速为100rpm,则将710000mm3/min的体积涂敷一分钟。
若由粉末供给部供给的热粘附性树脂粉末的表观比重为0.35,则每分钟涂敷速度为249g/min。
通过调节粉末排列辊的转速和循环带的移动速度,可调节涂敷在循环带上的热粘附性树脂粉末的涂敷厚度。
