摘　　要：研究不同裂解温度下废旧轮胎裂解炭黑的性质及其在天然橡胶中的应用,并与炭黑N330和N660进行对比。结果表明:与炭黑N330和N660相比,裂解炭黑的吸碘值大,结构度偏低,灰分含量偏高;裂解温度越高,裂解炭黑的理化性能越好;裂解炭黑填充胶料的门尼粘度比炭黑N330填充胶料略高,t 90缩短;裂解炭黑填充胶料的拉伸强度与炭黑N660填充胶料相当,略小于炭黑N330填充胶料;对比3种裂解炭黑,裂解炭黑S1填充胶料的拉伸强度最大,裂解炭黑S3填充胶料的300%定伸应力最大;在相同应变范围内,裂解炭黑S3填充胶料的损耗因子较小,生热较低。The properties of pyrolysis carbon black from waste tires at different pyrolysis temperatures and its application in natural rubber were studied,and compared with carbon black N330 and carbon black N660.The results showed that,compared with carbon black N330 and N660,pyrolysis carbon black had a higher iodine absorption value,a lower structural degree,and a higher ash content.The higher the pyrolysis temperature was,the better the physical and chemical properties of pyrolysis carbon black was.The Mooney viscosity of pyrolysis carbon black filled compound was slightly higher than that of carbon black N330 filled compound,and t90 was shortened.The tensile strength of pyrolysis carbon black filled compound was equivalent to that of carbon black N660 filled compound,but slightly lower than that of carbon black N330 filled compound.Among three types of pyrolysis carbon black,the tensile strength of pyrolysis carbon black S1 filled compound was the highest,and the modulus at 300%elongation of pyrolysis carbon black S3 filled compound was the highest;within the same strain range,the loss factor of pyrolysis carbon black S3 filled compound was smaller and the heat build-up was lower.
