Interfacial chemistry and mechanical effects of a multifunctional processing additive on carbon black filled rubber

摘要: The interfacial effects of a multifunctional additive (MFA), the n-tallow-propane-1,3-diamine salt carboxylic acid, on carbon black filled rubber have been studied. surfaces three normal-cure-rate blacks, differing nitrogen BET surface areas, were characterised by X-ray photoelectron spectroscopy (XPS) and vapour-phase chemical derivatisation found to contain very few functional groups. MFA has decompose at ca. 120 °C decomposition generate diamine acid species. Bound rubber, determined o-xylene extraction, was decrease with addition limiting bound value obtained loading that corresponds monolayer coverage surface. reduction is attributed release immobilised within agglomerates, as result improved dispersion. mechanical properties also improve again this dispersing effect black.
