Abstract

The invention discloses a polyethylene color master batch suitable for an irradiation crosslinking process and a preparation method of the polyethylene color master batch, and relates to the field of polyethylene color master batches. Linear low-density polyethylene, high-density polyethylene, maleic anhydride grafted polyethylene, magnesium hydroxide, heavy calcium carbonate, titanium dioxide, an antioxidant, butyl titanate, chlorinated paraffin, a crosslinking aid, pigment and a flame retardant are uniformly mixed; then putting the mixture into a double-screw extruder for extrusion and granulation; the polyethylene color master batch solves the problems that when an existing polyethylene color master batch is applied to radiation crosslinking, the phenomena of oxidative decomposition of a polymer, formation of unsaturated double bonds, material discoloration and the like are caused, the use of the polyethylene color master batch is seriously influenced, and the flame retardance of the color master batch is poor. The antioxidant is added to increase the oxidation resistance of the polyethylene color master batch, the chlorinated paraffin is added to increase the toughness of the color master batch, the flame retardant is added to improve the flame retardance of the color master batch, the crosslinking degree during radiation crosslinking is effectively improved through the crosslinking aid, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of polyethylene color masterbatch, in particular to a polyethylene color masterbatch suitable for an irradiation crosslinking process and a preparation method thereof. Background technique [0002] Color masterbatch is a mixture of resin and a large number of pigments or dyes to form a high-concentration color. Color masterbatch, also known as color species, is an aggregate prepared by uniformly loading super-constant pigments or dyes in resin. Mixing a small amount of color masterbatch and uncolored resin during processing can achieve the coloring resin or product of the design pigment method. The color masterbatch is widely used in polyethylene, polypropylene, polystyrene, ABS, nylon, PC , PMMA, PET and other resins, produced colorful fibers, clothing, daily plastics, wires and cables, household appliances, agricultural films, auto parts, health care equipment and other products. [0003] Polyethylene color masterb...
