| titleOfInvention | Preparation method of white carbon black wet masterbatch |
| abstract | a preparation method of white carbon black wet masterbatch, belonging to the field of masterbatch preparation. The method solves the defects of low production efficiency, high equipment energy consumption and difficult waste liquid recovery in the wet method for preparing the masterbatch in the prior art, further improves the dispersion degree of the white carbon black in the masterbatch, and further improves the mechanical property of vulcanized rubber. The preparation method comprises the steps of adding the white carbon black and the solvent into a reaction device, stirring for 3-8 hours at the temperature of room temperature to 50 ℃, then adding the latex, continuing to stir for 3-8 hours at the temperature of room temperature to 50 ℃, then adding the precipitator to obtain a mixed solution, finally pouring the mixed solution into a filter screen, and extruding and drying the precipitate to obtain the master batch. The method has the advantages of simple process, high production efficiency and low equipment energy consumption, and through experimental detection, the obtained masterbatch white carbon black has the dispersion grade of 9, the tensile strength after vulcanization is 19-23Mpa, the elongation at break is 685-750%, and the hardness is 58-68A. |
