Description
technical field
[0001] The invention belongs to the field of chemical industry, and in particular relates to a rubber composition. Background technique
[0002] With the increase in performance and functionality of automobiles, the performance requirements for tires are increasing year by year. One of them is the development of tires that are fuel-efficient while maintaining grip on wet roads, that is, wet grip. Carbon black has been used as a reinforcing filler for tire treads, but recently, due to the above-mentioned expectations, ultrafine particle silica, which has better low hysteresis loss and wet skid resistance than carbon black, has been used for tire treads. Reinforcing fillers for surface use (for example, refer to US Patent No. 5,227,425). However, silica-based fillers have hydrophilic silanol groups on the surface, and thus have a lower affinity for rubber molecules than carbon black, so although silica-based fillers are excellent in low hysteresis loss and w...
