Maleimidopropyltriethoxysilane grafted natural rubber(MISNR) were prepared by reaction of maleic anhydride grafted natural rubber(MNR) and 3-aminopropyl triethoxysilane(APTES). MISNR were used as the compatibilizer of Natural rubber(NR)/SiO2 composites. NR/SiO2 composites were prepared by 3 step mixing procedures including the masterbatching process. The final mixtures were cured with optimum cure condition, which was established by the rheometer. The effects of compositional variation and the amounts of compatibilizer in the composites on the cure characteristics, morphology, thermal stability, physical and mechanical behaviors were investigated. The composites having MISNR had shown cure characteristics, physical and mechanical properties superior to those without MISNR. SiO2 particles in the former appeared to be more uniform and reduced in size compared with the latter. |
