摘要： An antistatic inorganic filler comprises an inorganic filler, an organic dispersant applied onto the surface of the inorganic filler and an organic antistatic agent applied onto the organic dispersant layer. The inorganic filler may be prepared by a method comprising the steps of wet-grinding an inorganic filler in the presence of an organic dispersant, drying the ground inorganic filler and then mixing it with an organic antistatic agent; or a method comprising the steps of wet-grinding an inorganic filler in the presence of an organic dispersant, adding an organic antistatic agent to the resulting slurry of the ground filler and then drying the mixture. The inorganic filler shows an effect of imparting long-lasting antistatic properties to plastic and rubber materials in addition to the effects as the filler such as excellent rigidity, heat resistance and impact resistance.
