摘要： This invention is based upon the discovered that crosslinked core-shell particles can be used as a filler in low cost emulsion styrene-butadiene rubber (ESBR) with excellent results being attained. In fact, such core-shell particle filled ESBR exhibits performance similar to silica filled solution styrene-butadiene rubber (SSBR) in terms of dynamic response, Payne effect, rebound and tan δ at 0° C. and 100° C. The utilization of such crosslinked core-shell particles in rubber compounds offers the additional advantage of weight reduction since the core-shell particles are significantly less dense than carbon black or silica fillers. The use of the crosslinked core-shell polymers of this invention in rubber formulations in place of silica also offers the advantage of not needing any expensive silane coupling agents to attain required levels of polymer/filler interaction. Accordingly, no silane coupling agent is used in the rubber compounds of this invention which leads to reduced cost. Cost can be further reduced by virtue of the fact that compound mixing conditions can be substantially relaxed as compared to mixing silica containing rubber formulations. The present invention more specifically discloses A rubbery composition which is comprised of (1) an emulsion styrene-butadiene rubber, (2) carbon black, and (3) core-shell particles, wherein the core-shell particles are comprised of (a) a crosslinked elastomeric core comprised of repeat units that are derived from at least one diolefin monomer, and (b) a polymeric shell which is derived from at least one vinyl aromatic monomer.
摘要翻译： 本发明基于发现交联的核 - 壳颗粒可以用作低成本乳液丁苯橡胶（ESBR）中的填料，并获得优异的结果。 事实上，这种核 - 壳颗粒填充的ESBR在0°C和100°C的动态响应，Payne效应，回弹和tanδ方面表现出与二氧化硅填充溶液苯乙烯 - 丁二烯橡胶（SSBR）相似的性能。 橡胶化合物中的这种交联的核 - 壳颗粒提供了减轻重量的另外的优点，因为核 - 壳颗粒比炭黑或二氧化硅填料密度明显更低。 在橡胶配方中使用本发明的交联的核 - 壳聚合物代替二氧化硅也提供了不需要任何昂贵的硅烷偶联剂来获得所需水平的聚合物/填料相互作用的优点。 因此，本发明的橡胶化合物中不使用硅烷偶联剂，导致成本降低。 与混合含二氧化硅的橡胶配方相比，由于化合物混合条件可以基本上松弛，所以可以进一步降低成本。 本发明更具体地公开了一种橡胶组合物，其包含（1）乳液丁苯橡胶，（2）炭黑和（3）核 - 壳颗粒，其中核 - 壳颗粒由（a）组成， 由衍生自至少一种二烯单体的重复单元组成的交联弹性芯，和（b）衍生自至少一种乙烯基芳族单体的聚合物壳。
