中文摘要:
      本文对比研究了裂解炭黑(PCB)和N660 的化学性质及其在气密层配方中的应用情况。研究发现,PCB的吸碘值、氮吸附全比表面积和外比表面积、DBP和CDBP吸收值均高于N660,但是灰分含量高达20.3%,这些特性影响了PCB对气密层橡胶的补强性。与N660相比,填充PCB的橡胶Payne效应更加显著,定伸应力稍高,而拉伸强度和扯断伸长率略有降低,玻璃化转变温度升高1.62°C且高温区损耗因子更低,气密性基本维持不变,这些性能受到PCB化学特性和高灰分含量的共同影响。PCB作为一种替代填料,应用于轮胎气密层中具备一定的潜力。
英文摘要:
      In this paper, the chemical properties of pyrolysis carbon black (PCB) and N660 and their applications in the formula of inner-liner were compared. It is found that the iodine absorption numbers, total and external surface areas by nitrogen adsorption test method, DBP and CDBP absorption numbers of pyrolysis carbon black are higher than N660. But the ash content reaches up to 20.3%. The reinforcement effect for the inner-liner is affected by PCB’s properties. Compared with N660, the Payne effect of the PCB filled rubbers is more obviously, the stresses at 200% and 300% elongation are slightly higher, the tensile strength and elongation at break are reduced, the glass transition temperature is increased by 1.62 °C and loss factor is lower during the high temperature, air tightness remained essentially unchanged and the air impermeability is basically unchanged. These properties of composites are impacted by the PCB’s chemical properties and high content of ash. As an alternative filler, PCB has a potential use in tire inner liners.
