Rubber composition for coating tire cord |
摘要 |
The object of the present invention is provide a rubber composition for coating a tire cord, which improves adhesion with a tire cord and has an effect of recovering adhesion with a tire cord at hygrothermal aging with maintaining the initial vulcanization rate. The present invention relates to a rubber composition for coating a tire cord comprising 0.7 to 3 parts by weight of benzothiazolyl sulfenamide or benzothiazolyl sulfenimide represented by the chemical formula (1): (wherein R1 is a linear alkyl group having a branched structure of 3 to 16 carbon atoms, and R2 is a linear alkyl group having a branched structure of 3 to 16 carbon atoms or a benzothiazolyl sulfide group) and 3 to 7 parts by weight of sulfur based on 100 parts by weight of a rubber component containing at least 60% by weight of a natural rubber and/or an isoprene rubber. |
