接枝炭黑表面性质研究

STUDY ON THE SURFACE CHARACTER OF GRAFTED CARBON BLACK

研究了由聚合物表面接枝改性炭黑和氯化钾水溶液组成的分散体系中炭黑粒子表面ｚｅｔａ电位的变化，探讨了阴离子表面活性剂十二烷基苯磺酸钠（ＬＡＳ）和阳离子表面活性剂十二烷基苄基二甲基氯化铵（１２２７）在普通炭黑和聚合物接枝改性炭黑表面的吸附行为。

Systems of carbon black grafted by polymerpotassium chloride queous solution were studied.The experiments included that the relationship between concentration of surfactants which involving dodecyl benzen sulfonate sodium and dodecyl benzyl dimethyl ammonium chloride, and zeta electric potantial on the surface of carbon black and polymer graft carbon black.
