摘要

The reinforcement of octamethylcyclotetrasiloxane (D-4) grafted styrene butadiene rubber (SBR-g-D-4) with in situ generated silica was performed using the sol-gel reaction of tetraethoxysilane (TEOS) in latex. The characterization of SBR-g-D-4 and in situ generated silica reinforced SBR-g-D-4 was investigated by Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The grafting efficiency of the styrene butadiene rubber (SBR) was determined by a gravimetric method. It was found that the constant silicon content and the grafting efficiency of SBR were 1.72% and 0.13 wt% when the weight ratio of D-4 to SBR was 0.20. The effects of the D-4 and in situ generated silica content on the curing characteristics, mechanical properties and morphology of SBR latex were investigated. The mechanical properties of in situ generated silica reinforced SBR-g-D-4 vulcanizates were improved significantly compared to raw SBR vulcanizate when the in situ generated silica content was 18.05%. Compared with silica reinforced SBR-g-D-4, the tensile strength, wet skid resistance and rolling resistance of the in situ generated silica reinforced SBR-g-D-4 were better. This is because of the higher crosslinking degree in the SBR-g-D-4 matrix and the strong chemical bond between SBR-g-D-4 molecular chains and in situ generated silica. Scanning electron microscopy analysis revealed good silica filler dispersion in all the reinforced SBR-g-D-4 vulcanizates.
