    Abstract: The present invention is directed to bead wires which has a Cu/Sn deposit having an Sn content of 9 to 13% by weight and a Cu content of 91 to 87% by weight, in an amount of 0.65 to 0.85 g per kilogram of the wire. The present invention is also directed to rubber-coated bead wires for tires comprising the plated bead wire as mentioned above, a rubber layer formed on the bead wire from a composition comprising 100 parts of a rubber polymer, 80 to 140 parts of a carbon, 4 to 10 parts of sulfur, 0.4 to 0.9 part of a vulcanization accelerator, 10 to 7 parts of zinc oxide, and 1 to 4 parts of stearic acid, and to tires prepared by using the above-mentioned bead wires. The bead wires of the present invention have excellent adhesion between the plated bead wire and the rubber layer, so that the tires obtained using such bead wires avoid wild wires.

    Abstract translation: 本发明涉及具有Cu含量为9〜13重量%且Cu含量为91〜87重量%的Cu / Sn沉积物的珠丝,其量为0.65〜0.85g /千克 线。 本发明还涉及用于轮胎的橡胶涂覆胎圈丝,其包括如上所述的镀覆胎圈丝,由包含100份橡胶聚合物,80至140份碳的组合物形成在胎圈丝上的橡胶层, 硫磺4〜10份,硫化促进剂0.4〜0.9份,氧化锌10〜7份,硬脂酸1〜4份,以及使用上述珠丝制备的轮胎。 本发明的胎圈丝在电镀胎圈丝和橡胶层之间具有优异的粘合性,从而使用这种胎圈丝获得的轮胎避免了野生线。
