| 摘 要： | 对废轮胎热解炭黑进行了硫酸酸洗以及酸洗后加入硬脂酸两种改性处理方法，测定了热解炭黑、酸洗炭黑和硬脂酸改性酸洗炭黑的粒径、比表面积和表面性质。研究表明：热解炭黑是由许多微米级的颗粒构成的，灰分含量很高，酸洗可明显减少灰分，酸洗后炭黑比表面积略有增加;酸洗及硬脂酸改性可以增加热解炭黑挥发分的含量。热解炭黑的表面覆盖有碳质沉积物，极性较低，更加亲油，改性后有部分极性官能团暴露出来，含氧官能团数量增加。

| Abstract: | Modification of pyrolytic carbon black(CBp)was carried out by acid washing(washed carbon black,WCBp)and then added with stearic acid(stearic acid modified WCBp,SWCBp).These three carbon black samples were characterized by using X-ray fluorescence spectroscopy(XRF),scanning electron microscope(SEM),X-ray photoelectron spectroscopy(XPS),etc.The CBp is composed of carbon particles in micron scale containing a large proportion of ash.After acid washing,the ash content decreases from 20.46% to 8.65%.Both the WCB... |
