采用“填料粒子相互作用距离”的新观点，研究了炭黑和白炭黑增强的NR的填料网络结构和动态性能。结果表明，当白炭黑和炭黑填充份数相同时，由于白炭黑尺寸较小，在NR基体中相互作用距离小，易形成相互作用较强的填料网络。动态测试发现，白炭黑填充混炼胶比炭黑填充混炼胶具有更明显的 Payne效应；白炭黑填充硫化胶具有更低的滞后损失和更小的生热。“,”The filler network and dynamic mechanical characteristic of natural rubber filled by car‐bon black or silica was studied through a new scientific view“Interaction‐Distanceof Filler Particles” . The results showed that silica had shorter interaction‐distance and much stronger filler network in rubber as a result of its smaller size than that of carbon black .Dynamic test founded ,Payne effect of compound filled by silica was stronger than that of carbon black ,while silica filled vulcanizates had lower hysteresis loss and smaller heat built‐up than silica filled ones .
