填料的补强作用取决于填料-橡胶相互作用的性质以及填料在弹性基质内的分散情况。这两个过程相互关联,并且受制于原生粒子尺寸及其分布、形态、结构和本点能量分布,以及填料表面的官能团。白炭黑业已被认为是橡胶补强的一种重要填料,并已被用来部分甚至完全替代炭黑。然而,白炭 The reinforcing effect of the filler depends on the nature of the filler-rubber interaction and the dispersion of the filler within the elastic matrix. The two processes are interdependent and are governed by the size of the primary particle and its distribution, morphology, structure and energy distribution at the point, as well as the functional groups on the surface of the filler. Silica has been considered as an important filler for rubber reinforcement and has been used to partially or even completely replace carbon black. However, white carbon
