Traditional plastic functional masterbatch processing methods can be divided into two-roll open-milling method, internal mixing method, and extrusion method according to the process route. Commonly used equipment includes twin-roller, single-screw extruder, twin-screw extruder, and compaction. Machine and other mixing equipment.

The functional masterbatch prepared by this method has disadvantages such as uneven distribution of the auxiliary agent in the carrier resin, poor cross-section adhesion between the auxiliary agent and the carrier resin, and complicated production processes.

In response to the above-mentioned shortcomings, many new processing technologies have been developed. New functional masterbatch processing technologies include (1) carrier resin selection and processing technology; (2) polymer encapsulation technology; (3) liquid phase blending method; (4) ) Melt-phase blending method; (5) Molecular self-assembly.
