摘要：
Environmental and water cutting rubber powder (RP)-natural rubber (NR) composites and surfaces modification rubber powder (MRP)-NR composites were prepared. Effects of the content of RP and water cutting rubber powder(WRP) on the mechanical and dynamic mechanical properties of the composites were investigated. The infrared and thermogravimetric analysis show that the main rubber of the RP is NR and styrene-butadiene rubber (SBR).The structure of the main chain has no obvious change by modification, which was confirmed by thermogravimetric analysis. The processing property of MRP-NR composites was characterized by rubber process analyzer and the dispersion of rubber powder was characterized by a carbon black dispersing instrument. The results show that the compatibility of the MRP and NR has been improved and the processing property of MRP-NR composites is better than RP-NR composites. The dispersion of RP in NR gets worse with the increase content of RP, compared with the RP, MRP gets more separation and distribution in NR matrix, the tensile strength of MRP-NR composites is 27.9 MPa. © 2018, Editorial Office of Acta Materiae Compositae Sinica.
