Abstract:
      The effect of surface modifiers on the properties of nanoclay/natural latex composites was investigated．The results showed that the tensile strength of the vulcanized natural latex film before and after heat aging were significantly improved after the nanoclay was modified by alkyl surfactant．Cetyltrimethylammonium bromide（CTAB） had the best modification effect on nanoclay．When the amount of modified nanoclay was 2 phr，the tensile strength of vulcanized natural latex film was the highest．CTAB modified nanoclay could improve the storage stability，viscosity and mechanical stability of compounded natural latex，and raisen the physical properties and heat aging resistance of vulcanized natural latex film，showing good reinforcement effect．
