The paper systematically researched the surface modiifcation agent systems and processes of muscovite powder, and evaluated the modiifcation effect by the mechanical properties of muscovite/NR/SBR composite. The results showed that the suitable surface modiifcation condition of muscovite powder was modiifer WD-60 dosage 1.5%, activator PEG6000 2.0%, activator CTAB 1.0%, thinner ethanol 1.0%, stearic 2.0%, modiifed temperature 100℃, modiifed time 20 min. And under this condition, the tensile strength, 300% modulus, elongation at break, tear strength and hardness of the muscovite/NR/SBR composite respectively reached 14.82 MPa, 2.35 MPa, 614.32%, 18.76 MPa and 56 HA, which all met the inter-national standards for pneumatic tires, car tires, agricultural tires cushion belt and soft sole heel.
