Abstract

The invention belongs to the technical field of high polymer materials, in particular to polyethylene color master batch and a preparation method thereof. The polyethylene color master batch is prepared by utilizing the fact that sodium pyrrolidonecarboxylate has a positive effect on the polyethylene color master batch. The polyethylene color master batch is prepared from the following componentsin parts by weight: 100-200 parts of high-density polyethylene, 15-35 parts of an ethylene-ethyl acrylate copolymer, 2-15 parts of nekal, 1-8 parts of 2-heptadecylimidazole, 15-30 parts of white oil,1-10 parts of a dispersing agent and 0.5-5 parts of a stabilizer. The polyethylene color master batch has good compatibility, can be easily mixed with various plastic products uniformly, is stable incolor and luster, excellent in mechanical property, small in shearing friction coefficient, high in surface smoothness and small in equipment abrasion, and facilitates production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a polyethylene color masterbatch and a preparation method thereof. Background technique [0002] Polyethylene (PE) is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -100 to -70 ° C), good chemical stability, and can withstand most acid and alkali erosion (not resistant to oxidation properties) acid). Insoluble in common solvents at room temperature, low water absorption. [0003] Adding various auxiliary materials to polyethylene masterbatch can significantly improve performance, but some auxiliary materials interfere with each other, and have various shortcomings while playing a positive role. For example, compatibility, color sta...
