    Abstract: A steel cord-rubber composite is provided, that has improved initial adhesion property and adhesion property against aging between the steel cord and the rubber composition with improved manufacturing cost efficiency. A steel cord-rubber composition composite includes a coating layer and a steel cord, and the coating layer includes an inner coating layer formed of a rubber composition containing a rubber component, a cobalt compound and sulfur and directly covering the steel cord, and an outer coating layer formed of a rubber composition of which contents of cobalt compound and sulfur are smaller than those of the inner coating layer and coating the outer portion of the inner coating layer.

    Abstract: In order that spaces, including a space in the central portion, inside a steel cord used as a reinforcement by being embedded in a tire or the like are filled with an uncured rubber, the uncured rubber is coated on plural steel filaments 115 which are then stranded in case of a single layer steel cord, the uncured rubber is coated on all of plural core filaments 329 which are then stranded along with outer layer filaments 330 in the same direction at the same pitch in case of a 2-layer steel cord of 1 stranding process, and the uncured rubber is coated on all or 2 to 4 core filaments 218 or on at least one of 3 or 4 steel filaments 408, 408null to form a core strand and outer layer filaments 410, 410null are stranded therearound in case of 2-layer steel cord of 2 stranding process. Consequently, it is possible to exhibit satisfactory corrosion resistance and satisfactory fatigue resistance as a steel cord, shorten a curing time in tire component assembling or the like to attain energy saving and prolong the life of a steel cord itself and the life of a tire or the like using the same as a reinforcement. Further, production can be performed at low cost.

    Abstract translation: 为了将包含在中心部分中的空间,通过嵌入在轮胎等中用作增强材料的钢丝帘线内的空间填充有未固化的橡胶,未固化的橡胶涂覆在多根钢丝115上 在单层钢帘线的情况下是绞合的,未固化的橡胶被涂覆在所有多个芯丝329上,然后在同样的方向上以相同的间距将外层丝330与外层细丝330一起绞合, 1绞合过程,未固化的橡胶涂覆在全部或2至4个芯丝218上或3或4根钢丝408,408'中的至少一个上,以形成芯股线,外层丝条410,410'在其周围被绞合 在2绞线的2线钢绳的情况下。 因此,作为钢帘线,可以显示出良好的耐腐蚀性和令人满意的耐疲劳性,缩短轮胎部件组装等中的固化时间,以达到节能,延长钢丝绳本身的寿命和轮胎的使用寿命 使用与加强件相同的类似物。 此外,可以以低成本进行生产。
