Abstract

The invention discloses coloring master batches for polyethylene and a preparation method thereof. The coloring master batches for polyethylene disclosed by the invention comprise the following components in percentage by mass: 70%-90% of pigment, 10%-20% of polyethylene resin, 3%-5% of dispersant, 0.1%-1% of antioxidant and 0.1%-1% of antistatic agent. Compared with the prior art, the coloring master batches for polyethylene have the beneficial effects that the prepared coloring master batches for polyethylene are applied to coloring of polyethylene products, have the characteristics of good dispersibility, uniform coloring, high concentration, little dosage and no influence on the mechanical property of the polyethylene products, and are low in cost, easy to color, convenient to use and capable of saving production time and raw materials and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a colored master batch for polyethylene and a preparation method thereof. Background technique [0002] Polyethylene (PE) is cheap, easy to form and process, and has many excellent properties, so it has a large market demand and a wide range of applications. With the development and application of plastics, more and more polyethylene products require coloring treatment. Generally, polyethylene coloring methods can be divided into three types: toner coloring, dyeing and dyeing, and masterbatch coloring. Toner coloring is very simple, but it has the disadvantages that it is easy to produce color spots, the color difference is not easy to control, and it has great environmental pollution. Dyeing and granulation Coloring is to mix pigments into plastic raw materials, and each plastic material has been colored, so the color of the finished product is stable and uniform, bu...
