【 摘 要 】

N-cyclohexyl-2-benzothiazole sulphonamide (rubber vulcanisation accelerator CZ) was grafted onto the surface of dispersible nano-silica (DNS) to obtain silica-loaded rubber vulcanisation accelerator CZ (DNS-CZ) through in-situ surface modification. A series of as-prepared DNS-CZ samples with different CZ loadings were used as the fillers to reinforce the composites made of solution styrene-butadiene rubber (SSBR) and butadiene rubber (BR). The effect of DNS-CZ fillers on the mechanical properties of the SSBR/BR composites was investigated in relation to the scanning electron microscopic observation of the filler dispersion in the rubber matrix. It was found that the CZ is chemically bonded onto the surface of nano-silica, thereby effectively reducing the polarity of the nano-silica and enhancing its compatibility with the rubber matrix. Therefore, the SSBR/BR composites filled with DNS-CZ exhibit greatly improved mechanical properties and Akron abrasion resistance than the counterparts filled with unloaded DNS. Particularly, when the loading amount of the CZ is set as 81.10 mmol/kg, the resultant SSBR/BR/DNS-CZ composite exhibits the best mechanical properties and Akron abrasion resistance, showing promising application for green tire tread.
