ABSTRACT

Properties of carbon blacks and carbon black/SBR rubber composites filled by surface modified carbon blacks wereexamined. Although the specific surface area of carbon blacks increased after the surface modifications with heat, acid, andbase, there were no obvious changes in resistivity. The composites filled by heat treated carbon blacks showed a higher tensilestrength and elongation than those filled by raw blacks. The acid and base treated carbon blacks filled composites also showedhigher tensile strength but similar elongation values with those filled by raw blacks. With increasing loading ratio, both tensilestrength and elongation increased, and appeared a maximum value at 30-40 phr. Modulus at 300% strain remained increasingwith further loading of carbon blacks. At the same loading, the heat treated black filled composites showed similar modulusvalues with composites filled by raw blacks but for base and acid treated black filled composites much higher values wereobtained. After the surface modification, the functional groups which played an important role in reinforcement action werechanged.
