Abstract

"COMPOSIçãO à BASE DE BORRACHA E PNEUMáTICO COM COMPONENTE DE COMPOSIçãO DE ELASTÈMERO à BASE DE DIENO COM DISPERSãO DE GRáNULO NO FORMATO DE ESPIGA DE MILHO". Essa invenção está relacionada com uma composição de borracha e pneumático possuindo no mínimo um componente de uma composição de borracha compreendida de no mínimo um elastómero com base em dieno, com a exclusão de elastómeros do tipo butila, que contém uma dispersão interna de grânulos no formato de espiga de milho. Tal componente de borracha pode ser, por exemplo, uma banda de rodagem de pneumático e/ou lona de borracha reforçada com corda e/ou correia. Uma banda de rodagem do pneumático utilizado para dirigir durante o inverno, embora não necessariamente limitado ao ato de dirigir durante o inverno, é constituída de uma composição de borracha contendo no mínimo um elastómero vulcanizável de enxofre a base de dieno possuindo uma Tg abaixo de -30<198>C e uma dispersão interna nesse ponto de grânulos no formato de espiga de milho. A superfície de rolamento da banda de rodagem do pneumático é configurada com uma combinação de micro-saliências de grânulos no formato de espiga de milho da citada dispersão interna de grânulo no formato de espiga de milho e micro-cavidades nesse ponto criadas por uma liberação de uma porção dos grânulos salientes no formato de espiga de milho durante o desgaste ou uso da superfície de rolamento da banda de rodagem do pneumático a medida que o pneumático está rodando. No minimo uma porção das citadas micro-saliências granulares com formato de espiga de milho pode ser recoberta por uma membrana relativamente fina de borracha para banda de rodagem. Os grânulos no formato de espiga de milho podem ser coloridos com um corante adequado de uma cor que não seja preta para contrastar com a banda de rodagem colorida para visualizar melhor a sua presença na superfície de rolamento da banda de rodagem. A composição de borracha da banda de rodagem pode conter opcionalmente também um compósito de amido/plastificante, éster sorbitan, composto doador de metileno, composto receptor de metileno ou combinação de compostos doador e receptor de metileno, e pode ser reforçada com negro-de-fumo, agregados de sílica amorfa sintética ou sua combinação.
