Abstract
本发明公开了一种用于太阳能电池板的导电塑料，由如下重量份的组份组成：低密度聚乙烯20‑30份、均聚聚丙烯50‑60份、聚碳酸酯20‑25份、乙烯辛烯共聚物10‑15份、导电炭黑10‑12份、聚丙烯接枝马来酸酐5‑8份、钛酸酯偶联剂2‑5份、苯基异氰酸酯1‑1.5份、抗氧剂168 0.6‑1.2份、甲基聚硅氧烷0.5‑0.8份，本发明的用于太阳能电池板的导电塑料在保证良好可用导电性能的情况下大幅减少了导电炭黑的使用量，导电炭黑优选用量更少的特导电炭黑，同时聚碳酸酯、苯基异氰酸酯和甲基聚硅氧烷的共同作用提高了导电炭黑的空间分布均匀性，在相同导电性能下使用的炭黑量更少，从而大幅提高了导电塑料的物理性能，延长了太阳能电池板的使用寿命。
Description
技术领域
本发明涉及一种导电塑料，更确切地说，是一种用于太阳能电池板的导电塑料。
背景技术
导电塑料是将树脂和导电物质混合，用塑料的加工方式进行加工的功能型高分子材料。主要应用于电子、集成电路包装、电磁波屏蔽等领域。导电塑料不仅在抗静电添加剂、计算机抗电磁屏幕和智能窗等方面的应用已快速的发展，而且在发光二极管、太阳能电池、移动电话、微型电视屏幕乃至生命科学研究等领域也有广泛的应用前景。此外，导电塑料和纳米技术的结合，还将对分子电子学的迅速发展起到推动作用。将来，人类不仅可以大大提高计算机的运算速度，而且还能缩小计算机的体积。因此，有人预言，未来的笔记本电脑可以装进手表中。
应用到太阳能电池板中的导电塑料因为导电填料量较大导致材料的力学性能下降，导电塑料的韧性明显下降，从而影响了太阳能电池板的使用寿命。
发明内容
本发明主要是解决现有技术所存在的技术问题，从而提供一种具有较好力学性能的用于太阳能电池板的导电塑料。
本发明的上述技术问题主要是通过下述技术方案得以解决的：

作为本发明较佳的实施例，所述的导电炭黑为XCF特导电炭黑，DBP值为310-330。
本发明的用于太阳能电池板的导电塑料在保证良好可用导电性能的情况下大幅减少了导电炭黑的使用量，导电炭黑优选用量更少的特导电炭黑，同时聚碳酸酯、苯基异氰酸酯和甲基聚硅氧烷的共同作用提高了导电炭黑的空间分布均匀性，在相同导电性能下使用的炭黑量更少，从而大幅提高了导电塑料的物理性能，延长了太阳能电池板的使用寿命。
