Description

太阳能板耐高温抗紫外线自粘膜
技术领域
本发明属于太阳能领域，具体涉及一种太阳能板耐高温抗紫外线自粘膜及其制备方法。
背景技术
因太阳能板表面拉丝与镀层的加工方法，及在长期强紫外线下使用的要求。一直以来，其表面保护膜均用PE基材涂履一层亚克力压敏胶作为保护膜，此类保护膜在紫外线下极易加速老化，而出现难撕膜，且易有残留，导致此类板材的良品率一直较低。
CN102241175A公开了一种高光质太阳能增产大棚膜，包括内层消雾层，中层防老化、防流滴层和外层防老化层三层结构，其特征在于，内层消雾层，中层防老化、防流滴层和外层防老化层分别由以下组分按重量份制备而成：内层消雾层：100份EVA，25份POE，14份内层母料；中层防老化、防流滴层：75份EVA，25份POE，25份LDPE，14份中层母料；外层防老化层：50份MLLDOE，25份POE，50份LDPE，14份外层母料；该技术中的内中外层母料中还添加了较多的功能助剂来达到防老化的效果，并且使用了稀土试剂，该技术配方过于复杂，并不能仅使用简单的POE、LDPE、PP材料来达到防老化的效果，且使用该技术配方和工艺制备的自粘膜非常难撕，产品效果不好。
CN103640288A公开了一种EVA自粘保护膜，由基膜层、中间层和自粘层三层共挤粘结的薄膜构成，其特征在于：所述基膜层由以下重量份的原料组成：LLDPE10-15份，LDPE2-4份；所述中间层由以下重量份的原料组成：LLDPE8-13份，LDPE2-5份，氯化EVA1-3份，色母0-6份，所述自粘层由以下重量份的原料组成：EVA30-40份，氯化EVA 3-5份，LLDPE4-6份，LDPE1-3份，乙二醇双硬脂酸1-3份。该技术中添加了EVA，耐高温性能不好，如果不添加EVA，自粘膜的粘着力差，不易粘贴也不易撕开，该技术无法实现即耐高温又耐撕的效果。
发明内容
为解决上述问题，本发明提供一种太阳能板耐高温抗紫外线自粘膜，由外层、中层、内层三层共挤吹膜形成，其特征在于，所述外层、中层、内层的质量比为10～20：30～50：30～60，
所述外层为粘性层，由POE制成；
所述中层由LDPE、MLLDPE及PP三种共混制成，所述中层中三种成分的重量比：LDPE：MLLDPE：PP＝4～1：1～4：1～5；
所述内层由LDPE和PP两种共混制成，所述内层中两种成分的重量比：LDPE：PP＝4～1：1～3。
优选的，所述外层、中层、内层的质量比为12～18：35～45：40～50。
优选的，所述外层、中层、内层的质量比为15：40：45。
优选的，所述中层中三种成分的重量比：LDPE：MLLDPE：PP＝2～1：1～2：1～3；
优选的，所述内层中两种成分的重量比：LDPE：PP＝2～1：1～1.5。
优选的，所述中层中三种成分的重量比：LDPE：MLLDPE：PP＝1.5：1.5：2；所述内层中两种成分的重量比：LDPE：PP＝3：2.5。
在吹制太阳能板耐高温抗紫外线自粘膜时，我们根据太阳能板板材特点，选用聚烯烃弹性体(POE)作为粘性层，其用量根据用户对粘性要求的不同来选择；中层则因为贴太阳能板用自粘膜要求有一定的拉伸性能及耐高温性能，故而我们则选用低密度聚乙烯(LDPE)、茂金属线性低密度聚乙烯(MLLDPE)及聚丙烯(PP)共混加工，其共混比例则随薄膜的厚度不同而不同，当薄膜厚度大时茂金属线性低密度聚乙烯(MLLDPE)及聚丙烯(PP)的用量则应少些，当厚度薄时则可相应增加LLDPE及PP的用量；内层则选用LDPE及PP的共混物，其共混比例则需配合中层混合比例的改变而改变，当中层PP的共混比例少，则内层也应相应减少PP的用量。
本发明还提供一种上述太阳能板耐高温抗紫外线自粘膜的制备方法，所述自粘膜采用三层共挤吹膜机加工，根据配比，在外层料斗中加入外层原料，在中层料斗中加入中层原料，在内层料斗中加入热封层原料；各料斗分别混合均匀后，经三层共挤吹膜机挤出，加工过程中外层螺杆温度为170～200℃，中层螺杆温度为170～190℃，内层螺杆温度为160～180℃，模头温度为180～210℃。
优选的，加工过程中外层螺杆温度为180～190℃，中层螺杆温度为175～185℃，内层螺杆温度为165～175℃，模头温度为190～200℃。
优选的，所述外层螺杆的转速为200～300rpm，所述中层螺杆的转速为300～400rpm，所述内层螺杆的转速为300～400rpm。
优选的，所述外层螺杆的转速为250rpm，所述中层螺杆的转速为345rpm，所述内层螺杆的转速为360rpm。
优选的，所述吹膜机吹膜时的吹胀比为2～3，牵引比为4～6。
优选的，所述吹膜机吹膜时的吹胀比为2.6～2.8，牵引比为4.6～5.3。
各层螺杆转速则根据各层物料挤出量的不同而有所不同，牵引比及吹胀比则根据薄膜的宽度及厚度不同而定。
本发明还提供一种根据上述的太阳能板耐高温抗紫外线自粘膜的用途，所述用途提高自粘膜在太阳能板上的耐高温性和易粘贴易撕性。
本发明的有益效果：
(1)本发明的自粘膜三层结构采用合理的组成和配比，该产品不但粘性能满足客户要求，且其耐高温性及拉伸性均较好，其相比于涂胶膜，在长期紫外线照射下耐老化性能好，而且其增粘较少；
(2)本发明中采用多种功能材料用共混共挤方式生产出来的自粘膜，填补国内空白，使该行业良率与制程通过率提高超过20％，同时其还具有环保及对被保护材料不产生二次污染的特点，其使用完毕后撕去不产生残留。

实施例3
采用三层共挤吹膜机加工，在外层料斗中加入15kgPOE，在中层料斗中加入21kgLDPE、13kg MLLDPE及16kg PP，在内层料斗中加入14kgLDPE、16kgPP；各料斗分别混合均匀后，加工过程中外层螺杆温度为180～190℃，中层螺杆温度为175～185℃，内层螺杆温度为165～175℃，模头温度为190～200℃，外层螺杆的转速为250rpm，所述中层螺杆的转速为345rpm，所述内层螺杆的转速为360rpm，经三层共挤吹膜机挤出，由外、中、内三层共挤经模头上吹成厚度为128um的筒膜；筒膜切边分开收卷后得到厚度为100um的自粘膜C。
对比实施例 对比自粘膜的制备
根据实施例1中三层中配方，在对比例中改变原料组成配比，是对比例中的原料配比低于实施例1的范围，并且不在本发明中给出的技术方案所述的范围内，其他工艺条件不变，制备得到对比自粘膜，具体数据见表1：
表1
效果实施例 自粘膜的性能对比
实施1至3中制备的自粘膜的物理性能进行对比，分辨检测了自粘膜的粘着力、断裂拉伸强度、断裂伸长率、透明度，表2指标性能降低率是将自粘膜应用在太阳能板上检测2个月(在45度高温下)前后的各项性能数据各五组去平均值，计算出其降低率，降低率越小，说明自粘膜的防老化性越好，粘着力检测方法采用GB/T 7124，断裂拉伸强度检测方法采用GB/T13022-1991，断裂伸长率检测方法采用GB/T 1040.1-2006，透明度检测方法采用GBT2410-2008，具体数据如表2：
表2
从表2数据结果可以看出，对比例中的自粘膜的粘着力低于实施例1，这说明实施例1制备的自粘膜的粘性较好，使用时自粘膜A比对比例容易撕开；从断裂拉伸强度、断裂伸长率、透明度的降低率来看，实施例1的降低率均小于对比例，这说明实施例1制备的自粘膜的防老化能力更强，在高温下保质期更长。
根据上述说明书的揭示和教导，本发明所属领域的技术人员还可以对上述实施方式进行变更和修改。因此，本发明并不局限于上面揭示和描述的具体实施方式，对发明的一些修改和变更也应当落入本发明的权利要求的保护范围内。此外，尽管本说明书中使用了一些特定的术语，但这些术语只是为了方便说明，并不对本发明构成任何限制。
