TH19586B - Charcoal - Google Patents

Abstract

Charcoal with CTAB greater than or equal to 140 m2 / g, CDBP greater than or equal to 115 cubic cm / 100 g, the coloring value greater than or equal to 135%, Delta D50 below or equal to 50 nm, Dmode lower or Equal to 72 nm, and the vacuumed volume index greater than or equal to 1.30 that made the rubber mixture Excellent resistance to tread wear And better abrasion resistance Offer to charcoal soot Additional features of this invention are the presence of N2SA greater than or equal to 150 sq m / g and less than 180 sq m / g and DBP greater than or equal to 140 cu cm / 100 g. Charcoal-based mixtures show abrasive resistance. And the tread wear resistance is increased when added Down to the level that is normally used Further revealing is that the carbon-soot rubber compound shows a higher ratio of tread wear / hysteresis resistance at lower carbonation levels than those used accordingly. Normally in mixing rubber mixes All of these tires Silida may also be included to improve the look performance.
