摘　　要：本文研究了在炭黑（ＣＢ）填充硬质聚氯乙烯（ＲＰＶＣ）复合抗静电材料中添加微量ｎｍ级无机填料（ＮＭＩＦ）后对这种复合材料的力学性能、导电性能和加工流动性的影响。实验结果表明：在保证材料抗静电性能的前提下，添加０５％的ＮＭＩＦ即可使材料的冲击强度提高５６％，拉伸强度增加３ＭＰａ，同时其熔体流动性也有所改善。ＳＥＭ观察可见ＮＭＩＦ有助于ＣＢ在ＲＰＶＣ基体中的分散。お? It is found that the additive of 0.5% namometric inorganic filler in the production of rigid PVC filled with carbon black brings about beneficial properties to the final products. The impact strength of the carbon black filled PVC increase 56% and an additive 3MPa was obtained for its tensile strength, without any adverse effects in the conductive property of the rigid PVC.Apparently, the additive of a small amount of nanometric in organic filler promote carbon black distribution in the PVC.
