The present invention relates to a metal reinforcement rubberized with a sulfur-crosslinkable, substantially cobalt-free rubberizing mixture wherein the metal reinforcement is a steel cord containing one or more filaments wherein the filaments comprise steel substrate filaments and a coating partially or completely covering the steel substrate filaments, wherein the coating comprises brass consisting of copper and zinc, and wherein the coating is rich in iron in the brass in the form of particles having a size between 10 and 10000 nm. In order to optimize the vulcanization time, the rubberizing mixture contains 0.5 to 3 phr of at least one sulfenamide accelerator and/or at least one sulfenamide accelerator based on dibenzylamine.
本发明涉及一种经硫可交联的、基本上不含钴的橡胶化混合物橡胶化的金属加强构件,其中该金属加强构件是含有一根或多根细丝的钢帘线,其中这些细丝包括钢基材细丝和部分或完全覆盖该钢基材细丝的涂层,其中该涂层包括由铜和锌组成的黄铜,并且其中该涂层富含在该黄铜中的呈尺寸在10与10000nm之间的颗粒形式的铁。为了优化硫化时间,该橡胶化混合物含有0.5至3phr的至少一种次磺酰亚胺促进剂和/或至少一种基于二苄胺的次磺酰胺促进剂。
