    Abstract: The present invention relates to a continuous manufacturing process for a rubber masterbatch and a rubber masterbatch prepared therefrom. The manufacturing process comprises the following steps: step 1): a filler is added to a rubber solution, forming a rubber/filler/solvent mixture by stirring; and step 2): the solvent is removed and the mixture is dried, resulting in a rubber/filler masterbatch. The present invention also relates to a masterbatch prepared by the above-mentioned process and a rubber article prepared using the masterbatch. Compared to the wet mixing technologies in the prior art, the present invention has no specific requirements of rubber and filler, with a wider scope of usage. In addition, the filler has a high dispersion in rubber compounds, the production process thereof is continuous, highly efficient, low in energy consumption and labour, and thus low in cost.
