The production process of PA-based black masterbatch includes three stages: pre-treatment, compounding, and post-processing. The raw aniline material undergoes specific processing methods during the pre-treatment stage to ensure its good compatibility and stability with PA materials. Then, the treated aniline is compounded with PA resin through processes like mixing and melting to achieve uniform blending. After granulation, drying, and other post-processing steps, the black masterbatch meeting the requirements is produced. This preparation method ensures the black masterbatch has excellent dispersion and processing performance.
