Abstract

The invention relates to the technical field of coloring of masterbatch for cables, in particular to polyethylene masterbatch and a preparation method thereof. The polyethylene masterbatch is preparedfrom the following raw materials in parts by weight: 55-70 parts of thermoplastic polyethylene resin powder, 3-5 parts of an ethylene vinyl acetate copolymer (EVA) resin, 2-5 parts of heavy calcium carbonate, 1-3 parts of polyethylene wax and 25-35 parts of pigment. After the production method of the polyethylene masterbatch is adopted, the color changing time is shortened during production, andthe time is reduced by 30min or more during each time of color changing; the product yield is increased, and the loss, caused by chromatic aberration, of customers can be avoided; furthermore, the prepared masterbatch is good in dispersing property and high in coloring power, and has a wide application prospect in PE wires and insulated cables.

Description

technical field [0001] The invention relates to the technical field of color masterbatch for cables, in particular to a polyethylene color masterbatch and a preparation method thereof. Background technique [0002] Masterbatch is a mixture of resin and a large number of pigments or dyes formulated into a high concentration of color. Color masterbatch, also known as color species, is an aggregate made by uniformly loading super-constant pigments or dyes in resin. When processing, a small amount of color masterbatch and uncolored resin can be mixed to achieve the design pigment. Concentration of colored resins or products. Color masterbatch is widely used in polyethylene, polypropylene, polystyrene, ABS, nylon, PC, PMMA, PET and other resins to produce colorful fibers, clothing, daily plastics, wires and cables, household Electrical appliances, agricultural films, auto parts, health care equipment and other products. [0003] At present, in the manufacturing process of PE p...
