Title (EN) CARBON BLACK AND RUBBER COMPOSITION CONTAINING SAME
(FR) NOIR DE CARBONE ET COMPOSITION DE CAOUTCHOUC LE CONTENANT
Abstract:
(EN) Disclosed are carbon blacks having a CTAB of 65 to 85 m2/g and a DBP of from about 130 to 160 a/100g, which impart increased abrasion resistance and lower hysteresis to rubber compositions. Those products are made in a reactor having a combustion zone (10) of converging diameter (11), transition zone (12) and reaction zone (18). Feedstock to make carbon black is introduced at two points (32, 34).
(FR) Noirs de carbone ayant une valeur d'adsorption de bromure de cétyltriméthylammonium comprise entre 65 et 85 m2/g et un indice d'adsorption de dibutylphtalate compris entre environ 130 et 160 a/100 g conférant une meilleure résistance à l'abrasion ainsi qu'une hystérèse inférieure à des compositions de caoutchouc. Ces produits sont fabriqués dans un réacteur présentant une zone de combustion (10) de diamètre convergent (11), une zone de transition (12) ainsi qu'une zone de réaction (18). La charge d'alimentation de fabrication de noir de carbone est introduite au niveau de deux points (32, 34).
