摘　　要：研究裂解炭黑(CBp)在叉车轮胎胎面胶中的应用。结果表明:在胎面胶中以CBp等量替代炭黑N550,胶料的门尼粘度减小,使用20份CBp的胶料门尼焦烧时间相当,硫化胶的定伸应力和拉伸强度减小,拉断伸长率和撕裂强度增大,炭黑分散性下降;改性CBp硫化胶的耐磨性能优于CBp硫化胶。使用CBp等量替代炭黑N550可显著降低生产成本。The application of pyrolysis carbon black(CBp) in the tread compound of forklift tire was studied. The results showed that,when carbon black N550 was equivalently replaced by CBp in the tread compound,the Mooney viscosity of the compound decreased,the Mooney scorch time of the compound was similar as the dosage of CBp was 20 phr,the tensile modulus and tensile strength of the vulcanizate decreased,the elongation at break and tear strength increased,and the dispersion of carbon black decreased. The wear resistance of the vulcanizate with modified CBp was better than that of the compound with unmodified CBp. The production cost could be significantly reduced when carbon black N550 was equivalently replaced by CBp.
