摘　　要：对热裂解炭黑进行冲击研磨和高温处理,分别得到不同细度和表面有机物含量的热裂解炭黑,研究研磨细度和表面有机物含量两个因素对废轮胎热裂解炭黑性能的影响。结果表明,研磨细度和表面有机物含量是影响热裂解炭黑补强性能的重要因素。研磨后粒径越小,橡胶的拉伸强度和撕裂强度越高,当达到一定细度时,补强性能随粒径减小增幅缓慢;高温处理后甲苯抽出物透光率和挥发分降低,橡胶的定伸应力先增大后减小。Thermal pyrolysis carbon black with different fineness and surface organic species content was obtained by impact grinding and high temperature treatment.The effects of grinding fineness and surface organic species content on the properties of thermal pyrolysis carbon black of waste tire were studied.The results showed that the fineness of grinding and the content of organic species on the surface were important factors affecting the reinforcing properties of thermal pyrolysis carbon black.The smaller the particle size after grinding,the higher the tensile strength and tear strength of compound.When the fineness reached a certain level,the reinforcing performance increased slowly with the decrease of particle size.After high temperature treatment,the light transmittance and volatile content of toluene extract decreased,and the modulus first increased and then decreased.
