The invention relates to a rubber composition incorporating a preformed natural rubber-carbon black composite. According to one aspect of an exemplary embodiment, a rubber composition includes at least 20 phr of a composite material, at least 3 phr of a conjugated diene elastomer, a cure activator, and a sulfur-based curing agent. The composite material comprises reinforcing carbon black dispersed in natural rubber. The composite material and conjugated diene elastomer together provide at least 90 phr of a vulcanizable elastomer in the rubber composition. The rubber composition may further include a reinforcing filler in addition to carbon black. The reinforcing filler may include silica. The rubber composition may include at least 5 phr, or at least 8 phr, of silica, or up to 30 phr, or up to 18 phr of silica.
本发明涉及并入预成型天然橡胶‑炭黑复合材料的橡胶组合物。根据示例性实施方案的一个方面,橡胶组合物包含至少20phr的复合材料,至少3phr的共轭二烯弹性体,固化活化剂和基于硫的固化剂。所述复合材料包含分散在天然橡胶中的增强炭黑。所述复合材料和共轭二烯弹性体一起在橡胶组合物中提供至少90phr的可硫化弹性体。所述橡胶组合物可进一步包含除炭黑之外的增强填料。所述增强填料可包含二氧化硅。所述橡胶组合物可包含至少5phr、或至少8phr的二氧化硅、或至多30phr、或至多18phr的二氧化硅。
