  • The effects of micro and nano CaCo3 on the rheological and physico/mechanical behavior of an SBS/CaCO3 composite = Vpliv mikro- in nanodelcev CaCO3 na reološko in fizikalno/mehansko vedenje kompozita SBS/CaCO3
    Sadeghi, Mohsen ; Esfandiari, Amirhossein
    Different particle sizes of CaCO3 were used and this was confirmed with the X-ray diffraction method. The nano CaCO3 was added, from mass fraction (w) 1 % to 5 %, in the styrene butadiene styrene ... elastomer (SBS). Elastomer nanocomposites were compounded on a two-roll mill and molded in a compression-molding machine. The mechanical properties such as the tensile strength, the elongation at fracture, the modulus at 300 % elongation, the hardness, the specific gravity, the swelling index, and the flame retardancy were studied. The results were compared with a commercial CaCO3 ([mu]m) filled SBS. There was an improvement in the properties of the elastomer nanocomposites because of the uniform dispersion of the nano CaCO3 particles in the matrix that intercalates the elastomer chains. Hence, the degree of cross-linking increases multifold in comparison with the commercial CaCO3.
