Abstract

"PNEUMáTICO COM VEDANTE INCORPORADO CONTENDO SìLICA PRé-HIDROFOBIZADA". A presente invenção refere-se a um pneumático com uma camada de vedante com base em borracha butílica incorporada. A camada de vedante incorporada é de uma composição compreendida de borracha butílica parcialmente despolimerizada ou compreendida, alternativamente, de um compósito de polímero de borracha butílica parcialmente despolimerizada, juntamente com borracha de cis-1,4-poliisopreno parcialmente despolimerizada e/ ou polímero de poliisopreno líquido parcialmente despolimerizado, que contém uma sílica pré-hidrofobizada. A camada de vedante pode conter também um corante de uma cor não preta, que produz uma camada de vedante incorporada de uma cor que contrasta com a cor preta. Assim, a camada de vedante pode ser de cor preta ou pode ser de uma cor que contraste com uma cor preta. O precursor de vedante com base em borracha butílica é incorporado no pneumático como uma camada para formar um conjunto de pneu incluindo tal camada de precursor de vedante, em que a porção de borracha butílica ou de compósito com base em borracha butílica da camada de precursor de vedante é pelo menos parcialmente despolimerizada durante uma vulcanização subseqüente do pneu em uma temperatura elevada em um molde adequado para formar o pneu tendo a camada de vedante incorporada resultante. A composição de precursor de vedante pode conter adicionalmente argila convencional, plaquetas de argila, intercaladas, esfoliadas, carbonato de cálcio e/ ou cargas de grânulos de espiga de milho.
