Kaolin clay in silica tread compounds |
摘要 |
<p>The invention relates to a method for decreasing dynamic modulus without decreasing hardness in silica tread compounds in tires made in accordance with this method. The tread composition comprises an elastomer including a performance-enhancing package comprising silica, carbon black and a silica replacement. The replacement replaces up to about 40 percent by weight of the silica and yet maintains one or more selected performance properties as if the performance enhancement package were pure carbon black and silica. The replacement is kaolin clay present in conjunction with a silane coupling agent. In the method of the present invention kaolin clay is used as a replacement for about 5 to about 20 parts, by weight, of silica in the compounding of silica tread compounds.</p> |
