摘要
以漆酚为基体,石墨为导电填料,利用紫外光固化法制备漆酚/石墨复合导电涂料,讨论了涂膜中石墨的含量以及固化方式等对漆膜导电性能的影响,并测试了漆膜的常规物理机械性能。结果表明,在紫外光辐照下,漆酚/石墨混合物涂膜可快速固化。当石墨含量达到25%(wt%)时,漆膜的表面电阻率为442Ω.cm,硬度为6H,附着力2级,冲击强度为45kg.cm。
Polyumshiol/graphite composite conductive coating was prepared by UV irradiation, the effect of coneentration of graphite and curing method on electrical resistvity of composite film were studied. Physico - mechanical properties of polyurushiol/graphite composite film was also discussed. The results show that urushiol/graphite com- posite film was cured by UV irradiation. And the surface resistivity dropped shaply as the loading of graphite is 25%. The surface resistivity value is 442Ω. cm with 6H hardness of, 2 adhesion of and 45kg. em impact strength of.
