Abstract
Plant cellulose (PC) and used tire rubber powder (RP) were used as raw materials for preparing RP/PC composites, and the interface compatibility between PC and RP was studied. The compatibility was modified by adding r-aminopropyltrieth oxysilane (KH550) and bis-(γ-triethoxysilylpropyl)-tetrasulfide (Si69) coupling agent. The structure and morphology of RP/PC composites were characterized by scanning electron microscopy and their compatibility was preliminarily judged. The cross-linked structure and components of composite materials were studied by an infrared spectroscopy, X-ray photoelectron spectrometer and dynamic mechanical thermal analysis. The best coupling agent to improve the compatibility between RP and PC is Si69, and its best content is 2.5 phr. The composites treated with Si69 combine more closely and leave less space, and the interface compatibility between RP and PC is obviously improved.
