摘要炭黑是橡胶最重要的补强填料。将炭黑掺入橡胶硫化胶中，通常可提高橡胶的强度、延伸性、抗疲劳性、耐磨性等。为了使炭黑对橡胶硫化胶的性能产生有益的影响，炭黑必须充分分散在硫化胶中。事实上，分散性差本身就会产生有害影响（例如，产品寿命缩短、使用性能差、产品外观差、加工特性差、产品均匀性差、原材料浪费、成品废品率高和过度使用能源）。这些不足之处通常是由于存在较大的未分散的团块。本工作的开展是为了提高对炭黑分散过程的认识，包括对影响分散动力学的因素的认识。这里描述的工作集中在方法上。
Abstract Carbon black is the most important reinforcing filler for rubbers. The incorporation of carbon black into rubber vulcanizates generally gives improved strength, extensibility, fatigue resistance, abrasion resistance, etc. In order to exert its beneficial influence on the properties of rubber vulcanizates, the carbon black must be sufficiently dispersed therein. Indeed, poor dispersion can, in itself, give rise to detrimental effects (e.g. reduced product life, poor performance in service, poor product appearance, poor processing characteristics, poor product uniformity, raw-material waste, high finished-product rejection rates, and excessive energy usage). These inadequacies are generally the result of the presence of rather large, undispersed agglomerates. The present work was initiated in order to develop an improved understanding of the carbon-black dispersion process including the understanding of factors which affect the kinetics of dispersion. The work described here is focused on methodolo...
