Abstract
ABSTRACT To enhance the surface activity of pyrolysis carbon black (CBp), decrease surface impurity content, improve interfacial bonding, and dispersion in natural rubber, a green modification method was developed using hydrogen peroxide (H 2 O 2 ) as an oxidant and biodegradable citric acid as the acidic reaction system. Moreover, the filler dispersion, Payne effect, vulcanization characteristics, mechanical properties, and dynamical properties of modified CBp/natural rubber (NR) composites prepared by a novel twin‐screw shear dewatering process were evaluated. XRD, FTIR, and contact angle results showed that when CBp was modified by H 2 O 2 in the citric acid system, the surface impurity content decreased, and hydrophilicity, dispersion, and surface activity improved. The CBp/NR by H 2 O 2 /citric acid modification combined with the twin‐screw shear dewatering process had the best overall performance. Compared to unmodified CBp/NR, the tensile strength, resilience, and abrasion resistance were improved by 18.4%, 19.0%, and 46.6%, respectively, and the rolling resistance was reduced by 65.2%, providing a new method for the high‐value green recycling application of CBp in high‐quality natural rubber composites.
