Continuous manufacturing process for rubber masterbatch and rubber masterbatch prepared therefrom

摘要

The present invention provides a continuous method of making a rubber masterbatch and a rubber masterbatch made by such a method. A method for producing a rubber master batch comprises the steps of: 1) placing a filler in a rubber solution and obtaining a rubber / filler / solvent mixture through agitation; Step 2) The rubber / filler / solvent mixture obtained in step 1 is placed in a flocculator and brought into contact with one or several fluids selected arbitrarily in the nitrogen, water vapor, water, filler slurry, Thereby obtaining a mixture of the rubber / filler composite and the solvent; Step 3) The mixture prepared in Step 2 is introduced into a heating medium having a temperature higher than the boiling point of the solvent, and the polarity of the heating medium is different from the polarity of the solvent used, so that the mixture coagulates and desewalls, Forming a mixture of a rubber / filler composite and a solvent including the heating medium; Step 4) Separating the solvent and drying the remaining mixture to obtain a rubber / filler master batch.
