文摘

This paper investigated the styrene butadiene rubber (SBR)/nanoscale silica (SiO₂) composites vulcanized by electron-beam irradiation. Infrared spectra of the Si-O bond of SiO₂ before and after irradiation were studied, and the infrared absorption peak of the Si-O bond of the electron beam irradiated SBR/SiO₂ nanocomposites showed a blue shift of 20 cm−1 compared with that of SiO₂ before irradiation, whereas the absorption intensity decreased, indicating a change of interaction occurring between SiO₂ and SBR macromolecules. This paper also studied the effects of irradiation dose and SiO₂ filler loading on crosslink density and some mechanical properties of the irradiated SBR/SiO₂ composites. With the irradiation dose increasing, tear strength of the irradiated SBR/SiO₂ composites increased while crosslink density and tensile strength increased whole in the range of 300 kGy. With SiO₂ filler loading increasing, crosslink density, tensile strength and tear strength of the irradiated SBR/SiO₂ composites increased.
