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 resins and a preparation method. Background technique [0002] Polypropylene (PP) has the advantages of abundant raw material sources, low price, easy molding and processing, good rigidity and excellent mechanical properties, heat resistance, chemical resistance, excellent comprehensive performance, non-toxicity, and recyclability. Widely used in the automotive industry, household appliances, industrial supporting materials, packaging, office supplies, medical supplies and daily necessities and other industries, it has become the fastest growing variety of general plastics. In plastic products, especially black home appliances, one-shot polypropylene outer trim parts are more energy-efficient and material-saving than traditional metal outer trim parts. [0003] Polypropylene, on the other hand, has high electrical in...
