A series of nanocrystalline cellulose (NCC) reinforced natural rubber/butadiene rubber/styrene-butadiene rubber (NR/BR/SBR) blends were prepared via mastication NR/NCC, BR/SBR and other ingredients.Resorcinol hexamethylene tetramine (RH) was adopted to modify the interface between NCC matrix.The morphology, dynamic viscoelastic behavior, apparent crosslink density, mechanical performance property NR/BR/SBR/NCC discussed in detail.The results showed that uniformly dispersed composites RH could enhance adhesion matrix.According analysis, performed comparable reinforcing effect with carbon black (CB), modulus improved modification RH.Mechanical tests replacement CB by did not deteriorate properties composites.Besides, exhibited best properties, when 10 phr substituted CB.
