研究了工程轮胎裂解炭黑(CBp)的基本性质、微观结构及表面性质,考察了2种不同形态的 CBp 对丁苯橡胶混炼胶门尼粘度、硫化特性以及物理机械性能的影响,并与传统炭黑 N330和硅灰石粉(HQ)进行了比较。结果表明,粉料和粒料的 CBp 化学组成主要有 C、O、S、Si、Zn 和 Ca 等元素。与炭黑 N330相比,两种CBp 的吸碘值、DBP 吸油值和加热减量均较低,而灰分含量高很多。SEM 显示,2种 CBp 的粒子聚集体尺寸基本相同,比炭黑 N330大,粒料 CBp 的排列较紧密。红外光谱分析表明,CBp 与炭黑 N330的表面基团基本相同。分别填充粉料 CBp 和粒料 CBp 的 SBR 混炼胶门尼粘度明显增大,且后者大于前者。含 CBp 的混炼胶t 1 0和 t 90均缩短,且后者小于前者,两者均小于炭黑 N330和硅灰石填充的混炼胶。随着 2种 CBp 用量的增大,SBR 硫化胶的耐磨性、拉伸强度、撕裂强度和300%定伸应力均明显提高;粒料 CBp 填充的硫化胶性能优于粉料 CBp 硫化胶,两者性能均介于炭黑 N330和硅灰石填充的硫化胶之间。“,”The fundamental quality,micro-structure and surface groups of pyrolysis carbon black (CBp)made from waste truck tires were studied,and the effects of 2 kinds of CBp having different forms on Mooney viscosity,curing characteristics and mechanical properties of styrene-butadiene rub-ber were investigated,and they were compared with other fillers(carbon black N330 and HQ).The results showed that the chemical compositions of 2 kinds of CBp were C,O,S,Si,Zn and Ca.The i-odine adsorption value,DBP adsorption value,and heating loss of 2 kinds of CBp were lower than those of carbon black N330,and the ash content was higher than the later.SEM showed the aggre-gate size of 2 kinds of CBp particle were the same,but both larger than that of carbon black N330,and the arrangement of granules CBp was close together.FTIR showed that both CBp and carbon black N330 had the same surface groups.The Mooney viscosity of SBR compounds separately filled with powders CBp and granules CBp was greatly increased,and the Mooney viscosity of the former was higher than that of the later.The t 1 0 and t 90 of SBR compound containing CBp were shortened,and the later was shorter than the former,and the t 1 0 and t 90 of SBR containing CBp were shorter than those of SBR containing carbon black N330 and wollastonite powder.With the increase of the amount of pow-ders CBp and granule CBp,the mechanical properties of SBR were significantly improved.The prop-erties of the latter were better than those of the former,and the properties of SBR compound contai-ning CBp fell in between SBR compounds containing carbon black N330 and wollastonite powder.
