20120073720 | WIRE COAT COMPOSITIONS FOR RUBBER ARTICLES - The present invention is based upon the unexpected finding that lignin can be incorporated into wire coat stock composition to improve metal to rubber adhesion. It has been further found that lignin can be used as a replacement in whole or in part for conventional rubber-to-metal adhesion promoters, such as cobalt materials which are conventionally used in wire coat stocks to attain and maintain needed rubber-to-wire adhesion properties. In fact, wire coat stocks that contain lignin provide more that adequate rubber-to-metal adhesion characteristics for typical applications, such as in tires, and maintain needed levels of adhesion over long periods of product service. For instance, high levels of rubber-to-metal adhesion are maintained under harsh conditions, such as exposure to elevated temperatures and high levels of humidity. The utilization of lignin in wire coat stock formulations in accordance with this invention is also economically advantageous since lignin is a low cost alternative to most conventional adhesion promoting agents. Lignin is also environmentally friendly and does not present any known health hazards. Lignin is derived from wood and constitutes about 25 percent to 33 percent of the dry mass of wood. Accordingly, lignin is an abundant naturally occurring organic polymer which is a renewable resource since it is derived from trees. Accordingly, lignin represents a low cost, abundant, environmentally friendly, and highly effective alternative to conventional rubber-to-metal adhesion promoters. The present invention more specifically discloses a wire coat stock composition which is comprised of (1) a rubbery polymer, (2) about 40 phr to about 80 phr of carbon black, and (3) about 2 phr to about 30 phr of lignin. | 03-29-2012 |
20130048171 | TIRE CONTAINING SILICATE MICROFLAKES HAVING ENHANCED TRACTION CHARACTERISTICS - This invention discloses a tire having enhanced wet traction and ice traction characteristics.
