Title
(ZH) 一种路用压电复合材料及其制备方法
Abstract
(ZH)

本发明涉及的一种路用压电复合材料及其制备方法,其是由压电陶瓷和聚偏氟乙烯以及钛酸酯偶联剂和黑炭黑,压电陶瓷1份,聚偏氟乙烯0.24份,钛酸酯偶联剂0.2~0.3份,黑炭黑0.4~0.8份,通过热压法压制,大大提高了复合材料的结晶度,材料的力学性能提高(韧性增强),同时也提高了压电材料两相界面能,从而促进了材料的极化过程,此外,通过高压直流电场极化,大大提高材料的压电性能,本发明工艺简单,成本低廉,可制备出综合性能优异的路用压电复合材料,可制备大尺寸压电复合薄膜,有望应用于隧道、收费站减速带、桥头跳车路段等,实现产业化生产。
