Properties of Natural Rubber Composites with Kaolin and Silica Hybrid Filler

以高岭土和白炭黑作为增强剂,采用熔融共混法制备了一系列的天然橡胶(NR)复合材料,并对其微观结构、气体阻隔性能和力学性能进行了表征.结果表明,改性高岭土(MK)以片层结构,白炭黑(PS)以球状结构,均匀分散于NR基体之中;MK与PS单独填充NR时,随着MK填充量的增加,NR复合材料的气体阻隔性能逐渐提高,而且MK的增强和阻隔作用都优于PS;MK与PS并用填充时,混合物填充NR复合材料的阻隔性能、拉伸模量和拉伸强度都优于MK、PS单独填充的NR复合材料,填料并用更有效地改善了NR复合材料的气体阻隔性能和力学性能.
