Studies on processing of styrene butadiene rubber-CaCO3 nanocomposites by different mixing techniques and their performance properties Abstract A.Ahamad, C.B.Patil, P.P.Mahulikar, U.R.Kapadi, and D.G.Hundiwale* School of Chemical Sciences, North Maharashtra University, Umavinagar, Jalgaon - 425 001 Maharashtra, India E-mail- dghundiwale@yahoo.com, ab_ahad@rediffmail.com The nano particles of CaCO3 were synthesized by matrix mediated growth and controlled technique and was used as filler. The particle size of synthesized nano CaCO3 (35-60 nm) was determined by XRD and confirmed by Transmission Electron Microscope (TEM). The styrene butadiene rubber (SBR) -CaCO3 nanocomposites were prepared by using Brabender Plastograph. The mechanical and physical properties of SBR nanocomposites were determined .The fracture surface of SBR nanocomposites was observed by Scanning electron microscope (SEM). The results of Brabender processed SBR -CaCO3 nanocomposites were compared with two roll mill processed SBR -CaCO3 nanocomposites. The results showed that the reinforcement of CaCO3 nano-filler in SBR polymer matrix enhanced the properties of SBR nanocomposites as compared to pristine SBR composites in both the techniques. The substantial improvement in properties was observed in case of Brabender processed SBR -CaCO3 nanocomposites as compared to pristine and two roll mill processed SBR -CaCO3 nanocomposites. The enhancement in properties was observed in Brabender processing technique due to the higher shear rates which resulted in proper dispersion and mixing of nano CaCO3 in SBR polymer matrix and proper wettability of inorganic particles by polymer matrix. Keywords: - Styrene butadiene rubber (SBR), Nanocomposites, Brabender Plastograph, Scanning electron microscope (SEM)
