| Abstract: |
| Natural rubber（NR）/lamellar sodium-based montmorillonite（Na-MMT），styrene-butadiene
rubber （SBR）/Na-MMT and NR/SBR/Na-MMT masterbatches were prepared by emulsion blending
method，then the corresponding NR/SBR/Na-MMT nanocomposites were prepared，and the effect of Na-
MMT on the microscopic morphology，physical properties and wear resistance of the NR/SBR/Na-MMT
nanocomposites was investigated. The results showed that the dispersion of Na-MMT in the NR/SBR/Na-
MMT nanocomposites prepared by using the NR/Na-MMT masterbatch was the best，and the proportion of
Na-MMT in the exfoliated state was the largest，the dispersion of carbon black was also obviously improved，
and the lamellar Na-MMT could regulate the segregation behavior of carbon black in the NR/SBR/Na-
MMT nanocomposites to a certain extent. As a result，the tensile strength，stress at constant elongation and
elongation at break of the NR/SBR/SBR/Na-MMT nanocomposites were the largest，the Akron abrasion
was the smallest（0. 177 cm3），and the grooves on the worn surface was shallowest，showing the best wear
resistance. |
