Abstract:
Disclosed are a continuous manufacturing process for a rubber masterbatch and a rubber masterbatch prepared therefrom. The manufacturing process comprises: 1): a filler is added to a rubber solution, forming a rubber/filler/solvent mixture by stirring; 2): the rubber/filler/solvent mixture obtained in step 1) is fed into a coagulator, and is coagulated after optionally being brought into contact and mixed with one or more fluids of nitrogen, steam, water, aqueous slurry of filler, and oil in the coagulator, resulting in a mixture of a rubber/filler composite and a solvent; 3): the mixture obtained in step 2) is directly passed into a heating medium at a temperature higher than the boiling point of the solvent, the polarity of the medium being different from that of the solvent used, the mixture is coagulated and deswelled, and the solvent is evaporated rapidly, thereby forming a mixture of a rubber/filler composite and the solvent containing the heating medium; and 4): the solvent is removed and the remaining mixture is dried, resulting in a rubber/filler masterbatch.
