The effects of wet mixing process on the properties of silica/NR composites was ana-lyzed and studied,and the performance advantages of wet rubber prepared using emulsion co-precipi-tation method were identified.The results showed that compared with dry mixed rubber,wet mixed rubber exhibited lower filler network and higher silanization effect,resulting in advantages such as high filler dispersion,fast vulcanization rate,high crosslinking density,high tensile strength,low hysteresis loss and better dimensional stability.
