Abstract

The invention discloses a multifunctional black master batch for polypropylene resin. The multifunctional black master batch comprises the following components in percentage by weight: 25-35 percent of pigment carbon black, 1-4 percent of a carbon nanotube, 2-6 percent of a compatilizer, 2-8 percent of an aging-proof agent, 15-25 percent of a dispersing lubricating agent and 35-45 percent of carrier resin, wherein the carbon nanotube and the pigment carbon black construct an anti-static system together; and the aging-proof agent and the pigment carbon black construct an aging-proof system together. Polypropylene is effectively prevented from aging, and the requirements of coloring, color retention and dust pollution prevention on a one-step molded polypropylene external decorative part for black electrical appliances are met. The preparation method comprises the following steps of: adding the pigment carbon black, the carbon nanotube, the compatilizer, the aging-proof agent, the dispersing lubricating agent and the carrier resin into a high-speed mixer for mixing; feeding into a dual-screw extruder for extruding; and cooling, drying, granulating and packing to obtain a needed master batch. The multifunctional black master batch has the characteristics of small using amount of the carrier resin, low consumption of a master batch molding antioxidant and simple feeding in a molding process of downstream materials, and can be widely applied to colorization of polypropylene resin.

Description

technical field [0001] The invention relates to the technical field of plastic coloring, in particular to a multifunctional black masterbatch for 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 plastic products, especially black home appliances, one-time molded polypropylene exterior decorations are more energy-efficient and material-saving than traditional metal exterior decorations. [0003] Polypropylene has high electrical insulatio...
