The variation of Po, PRI, Mooney viscosity, vulcanization characteristics of the biological coagulated raw natural rubber during accelerated storage at 70 oC as well as the physico-mechanical properties and dynamical mechanical properties of the vulcanized rubber after vulcanization of the stored raw compounded rubber were investigated by use of the heat accelerated storage method. The results show that during accelerated storage of the biological coagulated raw natural rubber at 70 oC, the Po, PRI and Mooney viscosity decrease linearly; the t90, t10, t81 and t82 in vulcanization process increase gradually; the MH, ML and vulcanization rate decrease; the Shore hardness, elongation at break and tensile strength of the vulcanized rubber decrease with the increment of storage time, but the variations of modulus at 300;and 500;are not obvious; the storage modulus M of the vulcanized rubber and the peak value of the loss factor Tan increase, the viscoelasticity decreases, the skid resistance and rolling resistance remain substantially unchanged.
