Abstract

The invention provides antistatic and anti-aging white masterbatch for polypropylene (PP) resin. The white masterbatch comprises the following components in weight percentage: 8-12% of antistatic agent, 1-3% of compatilizer, 8-12% of antiager, 10-14% of pigment, 4-8% of dispersion lubricant and 51-69% of carrier resin, wherein, components of the antiager have good synergistic effect, thus effectively preventing PP and polyoxyethylene ether from being aged and meeting the requirements for coloration, color retention, light retention and dust pollution prevention of a one-time-molded external PP decorating part for white appliances. The preparation method of the white masterbatch comprises the following steps: mixing the antiager, the pigment, the dispersion lubricant and the carrier resin in a high-speed mixer; adding the antistatic agent and the compatilizer, stirring, and then adding the obtained mixed material to a double screw extruder for extrusion; and cooling, drying, granulating and packaging to obtain the needed masterbatch. The antistatic and anti-aging white masterbatch has the characteristics of less consumption of the carrier resin, low consumption of an antioxidant during the masterbatch forming process, and simple added materials in a forming process of downstream materials, and the masterbatch can be widely applied to coloring the PP resin.

Description

technical field [0001] The invention relates to the technical field of plastic coloring, in particular to a white masterbatch specially used for antistatic anti-aging of polypropylene resin and a preparation method thereof. Background technique [0002] Polypropylene (PP) has the advantages of abundant raw material sources, cheap price, easy molding and processing, good rigidity and excellent mechanical properties, heat resistance, chemical resistance, excellent comprehensive performance, non-toxic, recyclable, etc. It is widely used in the automobile industry, household appliances, industrial supporting materials, packaging, office supplies, medical supplies and daily necessities, and has become the fastest-growing variety of general-purpose plastics. In white plastic products, especially white home appliances, one-time molded polypropylene exterior decorations are more energy-efficient and material-saving than traditional metal exterior decorations. [0003] Polypropylene...
