Abstract

COMPOSIÇÃO DE BORRACHA DIÊNICA, PROCESSO DE PREPARAÇÃO DA MESMA, ARTIGO SEMI-ACABADO DE BORRACHA PARA PNEUMÁTICO, PNEUMÁTICA, E, BANDA DE RODAGEM DE PNEUMÁTICO. A invenção refere-se a uma composição de borracha diênica para pneumático à base de pelo menos (i) um elastômero diênico, (ii) uma carga reforçada inorgânica, (iii) um agente de copulação assegurando a ligação entre a carga inorgânica e o elastômero, a referida carga inorgânica compreendendo pelo menos uma sílica susceptível de ser obtida pelo processo de preparação do tipo compreendendo a reação de um silicato com um agente acidificante por meio do que se obtém uma suspensão de sílica, depois a separação e a secagem desta suspensão, caracterizada em que a reação do silicato com o agente acidificante é realizada de acordo com as etapas sucessivas seguintes: (i) coloca-se em contato (mistura) uma suspensão aquosa de sílica precipitada, apresentando um pH compreendido entre 2,5 e 5,3, com o agente acidificante e silicato, de tal modo que o pH do meio reacional seja mantido entre 2,5 e 5,3, (ii) acrescenta-se no meio reacional obtido o silicato e isto de modo a aumentar o pH do meio reacional até um valor compreendido entre 4,7 e 6,3.
