【摘要】：制备了炭黑(CB)填充高密度聚乙烯(HDPE)/乙烯-醋酸乙烯酯共聚物(EVA)双基体复合材料,研究了加料顺序、混合时间对复合材料导电性能的影响.结果表明,CB主要分布在HDPE相中;采用CB首先填充EVA然后与HDPE混合,或采用EVA/HDPE共混物与CB混合的加工策略,均可获得导电性较优的导电复合材料.然而,混合过程显著影响CB填充双基体复合材料的导电性.采用EVA/HDPE共混物与CB混合法加工复合材料,导电性受相形态演化影响较小.
[Abstract]:High density polyethylene (HDPE) / ethylene-vinyl acetate copolymer (EVA) double matrix composites filled with carbon black (CB) were prepared. The effects of feeding order and mixing time on the electrical conductivity of the composites were studied. The results showed that CB was mainly distributed in the HDPE phase. When CB is first filled with EVA and then mixed with HDPE, or EVA/HDPE blends are mixed with CB, conductive composites with better conductivity can be obtained. The electric conductivity of CB filled double matrix composites was significantly affected by mixing process, and the electrical conductivity was less affected by the evolution of phase morphology when EVA/HDPE blend and CB were used to process the composites.
