摘　　要：本课题研究了新型纳米碳材SG6在耐热输送带覆盖胶中的应用,通过对配方中的N660炭黑进行逐量替代,考察了SG6对胶料的硫化特性、物理机械性能、耐磨性能、动态力学性能、导热性能和导电性能的影响。结果表明,SG6从0份逐渐替代到24份,混炼胶的扭矩差值略微减小,t_(10)及t_(90)基本保持不变,门尼黏度略有降低;硫化胶硬度降低,拉伸强度,拉断伸长率以及定伸应力有所改善;同时可使耐热输送带覆盖胶动态生热有所降低,导热系数增大,表面电阻值明显降低,有效改善输送带覆盖胶产品的质量。This study investigates the application of a new type of nanocarbon material SG6 in heatresistant conveyor belt covering rubber.The influence of SG6 on the vulcanization characteristics,physical and mechanical properties,wear resistance,dynamic mechanical properties,thermal conductivity,and conductivity of the rubber compound was studied by gradually replacing N660 carbon black in the formula.The results showed that,as SG6 gradually increased from 0 parts to 24 parts,the torque difference of the mixed rubber slightly decreased,while t_(10) and t_(90) remained basically unchanged,and the Mooney viscosity slightly decreased;The hardness of vulcanized rubber is reduced,and the tensile strength,elongation at break,and tensile stress are improved;At the same time,the dynamic heat generation of the heat-resistant conveyor belt cover adhesive is reduced,the thermal conductivity coefficient increases,and the surface resistance value significantly decreases,effectively improving the quality of the conveyor belt cover adhesive product.
