虽然人们对炭黑的结构还不完全清楚，但X射线分析表明它是由碳原子的稠环层组成的。层中的不饱和度和不连续性可能为自由基的攻击提供位点，从而使炭黑成为特殊多官能类型的自由基受体。假设橡胶自由基和炭黑的组合，颗粒可以终止一个以上的剪切橡胶链。此外，附着在炭黑颗粒上的橡胶链也可以通过剪切而断裂，并通过与其他颗粒结合而终止。从这张图中可以预期的结果是橡胶和炭黑通过化学键结合在一起的网络。在橡胶溶剂中，这样的网络将是不溶的，并且仅仅变成溶胀的凝胶。橡胶在与炭黑研磨时的不溶解性有时已被报道，但证据不足以广泛得出可靠的结论。本文介绍了一个系统…
Abstract Although the structure of carbon black is imperfectly known, x-ray analysis has shown it to consist of layers of condensed rings of carbon atoms. Unsaturation and discontinuities in the layers are likely to provide sites for attack of free radicals, and thus make carbon black a radical acceptor of a special polyfunctional type. Assuming combination of rubber radicals and carbon black, a particle could terminate more than one sheared rubber chain. Furthermore, rubber chains attached to a carbon black particle could also undergo scission by shear and be terminated by combination with other particles. The result anticipated from this picture is a network of rubber and carbon black held together by chemical bonds. In rubber solvents, such a network would be insoluble and merely become swollen gel. Insolubilization of rubber on milling with carbon black has been reported on occasion, but the evidence is not sufficiently extensive to draw reliable conclusions as to its cause. This paper reports a syste...
