【 摘 要 】

Enhancing the carbon black (CB) dispersion and tensile strength of composites of styrene-butadiene rubber (SBR) using bio compatibilizer-alkanolamide (BALK) was carried out. The raw SBR was filled by N330 type of CB at a fixed concentration (thirty parts per hundred rubbers, phr). The BALK was Refined Bleached Deodorized Palm Stearin (RBDPS)-based additive, loaded into the composites at 1, 3, 5 and 7 phr. The BALK enhanced not only degree of CB dispersion but also tensile properties. It exhibited tensile and modulus enhancements, especially up to a five phr of addition. The morphological study proved that the five phr was the optimum BALK addition where the fractured surface of composites of SBR with five phr of BALK showed the greatest surface roughness and matrix tearing line.
