其他信息

  • 可燃性危险特性:可燃,燃烧产生刺激烟雾
  • 上游原料:氢氧化钠 --> 盐酸 --> 硬脂酸 --> 二水合氯化钡 --> 硝酸铅
  • 硬脂酸盐类热稳定剂:硬脂酸盐类热稳定剂主要是硬脂酸钙、硬脂酸钡、硬脂酸镉、硬脂酸镁、硬脂酸锂、硬脂酸锌、硬脂酸铝、双硬脂酸铝、硬脂酸铅、硬脂酸锶、硬脂酸钴、硬脂酸钠、硬脂酸亚锡等。它们的代表品种是硬脂酸钡 (barium stearate)。其结构式如下: 它由硬脂酸经烧碱皂化后,再与氯化钡溶液进行复分解制得。平均分子量682.6,为白色细粉,钡含量19.5%~20.5%。游离脂肪酸含量≤1%,水分≤1%,细度(200目通过) ≥99%。相对密度1.145,熔点225℃以上,不溶于水,溶于苯、甲苯、热的乙醇和其他非极性溶剂,在有机溶剂中加热溶解后经冷却后为胶状物。遇强酸分解为硬脂酸和相应的钡盐。在空气中易吸潮。它作为聚氯乙烯及氯乙烯共聚物的热稳定剂,也兼作润滑剂。其长期耐热性最好,润滑性优良。稳定效能优于硬脂酸钙,但低于硬脂酸铅。与镉皂、锌皂或环氧化合物并用,有优良的协同效应。通常用量为0.1%~2%。若添加少量的铅系稳定剂可以提高制品的电气性能。本品主要用于软质透明薄膜、片材和硬质板材、人造革及管材。在一般软质制品中,常与镉皂、镉- 锌或镉-铅皂类配合使用;在耐硫化人造革配方中常与锌皂并用; 在管材和电缆料中常与碱式铅盐和铅皂配合; 在波纹板中,常与镉皂、铅皂及碱式铅盐并用。本品还可用作耐高温脱模剂和机械用高温润滑剂。本品无硫化氢污染性,但有毒性。
