The invention has the advantages of high dispersion and strong weatherability.

Description

technical field [0001] The invention relates to a color masterbatch, in particular to a high-dispersion polyethylene color masterbatch, which belongs to the technical field of plastic additives. Background technique [0002] The emergence of color masterbatch has brought an innovation to the plastic processing industry. Adding color masterbatch to process plastic products has good dispersibility and no pigment particle pollution during processing, which greatly protects the health of production line workers. However, with the continuous development of the color masterbatch industry, problems have also emerged. Since the color masterbatch is a high-concentration pigment concentrate, when the plastic product is required to be opaque and the proportion is large, the problem of poor dispersion also occurs, especially Color masterbatch for the production of film products. In addition, after long-term use of plastic products, they are easy to become brittle and yellow, which affe...
