• Sterically hindered phenol antioxidant granules having balanced hardness
  申请人：Semen John

  公开号：US20050006627A1

  公开（公告）日：2005-01-13

  Sterically hindered phenol antioxidant additive granules are formed from a paste comprising an organic processing agent comprising a friability reduction agent. The friability reduction agent preferably is an alcohol, more preferably an alkanol having up to about 8 carbon atoms, most preferably methanol, ethanol, and/or isopranol. After drying, the granules consist essentially of the sterically hindered phenol antioxidant additive system. The granules have a balanced hardness that provides sufficient abrasion resistance while permitting ready dispersion into a polymer host.

  固态受阻酚抗氧化添加剂颗粒是由一种糊状物形成的，该糊状物包含一种有机加工剂，其中包括一种易碎性降低剂。易碎性降低剂最好是醇类，更优选具有最多约 8 个碳原子的烷醇，最优选甲醇、乙醇和/或异丙醇。干燥后，颗粒主要由立体受阻酚抗氧化添加剂系统组成。颗粒具有均衡的硬度，既能提供足够的耐磨性，又能随时分散到聚合物基体中。
