碳黑(carbon black),又名炭黑,是一種無定形碳。輕、松而極細的黑色粉末,表面積非常大,范圍從10-3000m2/g,是含碳物質(煤、天然氣、重油、燃料油等)在空氣不足的條件下經不完全燃燒或受熱分解而得的產物。比重1.8-2.1 由天然氣制成的稱“氣黑”,由油類制成的稱“燈黑”,由乙炔制成的稱“乙炔黑”。此外還有“槽黑” amp;ldquo;爐黑”。按炭黑性能區(qū)分有“補強炭黑” amp;ldquo;導電炭黑” amp;ldquo;耐磨炭黑”等??勺骱谏玖希糜谥圃熘袊?、油墨、油漆等,也用于做橡膠的補強劑

按生產

主要分為燈黑、氣黑、爐黑和槽黑。

據(jù)記載,中國是世界上早生產炭黑的。在古時候,人們焚燒動植物油、松樹枝,收集火煙凝成的黑灰,用來調制墨和黑色顏料。這種被稱之為“炱”的黑灰就是早的炭黑。

1821 年人們在北美地區(qū)用天然氣為原料生產炭黑,從此炭黑不再是“炱”那么簡單,它是“氣態(tài)或液態(tài)的碳氫化合物在空氣不足的條件下進行不完全燃燒或熱裂分解所生成的無定形碳,為疏松、質輕而極細的黑色粉末”大片油氣田相繼開采,源源不斷的原料供應推動炭黑生產由手工操作邁入了大規(guī)模工業(yè)化時代。

1912 年人們發(fā)現(xiàn)炭黑對橡膠具有補強作用,從此炭黑逐漸成為橡膠工業(yè)不可缺少的原材料。世界橡膠工業(yè)原材料耗用量排在位的是生膠,第二位的是炭黑;換言之,炭黑已成為消費量大的橡膠配合劑。炭黑的耗用量一般占橡膠耗用量的40%~50% ,也就是說,在橡膠配方中,通常每使用2 份橡膠就會搭配使用1 份炭黑。
