Composition of color high-concentration mono-color master batch for polyolefin

Abstract

The invention discloses a composition of a color high-concentration mono-color master batch for polyolefin. Carrier resin is polyolefin resin, and the polyolefin resin comprises metallocene polyolefin resin. The composition further comprises a toner and an additive, wherein the additive comprises a dispersing agent, a lubricating agent, a coupling agent, a compatilizer and a stabilizer, or a mixture of at least two of the dispersing agent, the lubricating agent, the coupling agent, the compatilizer and the stabilizer. The metallocene polyolefin resin is introduced for serving as carrier resin, and the toner and the conventional additive are added, so that the color high-concentration mono-color master batch is obtained. The mono-color master batch can be directly added during production of a polyolefin product, and different types of color high-concentration mono-color master batches can be matched and toned freely according to the color requirements of products, so that the dependence of toning and color control on a color master batch manufacturer is lowered greatly. The color high-concentration mono-color master batch has high dispersivity, is free from dust, and does not pollute production environments.

Description

technical field [0001] The invention relates to the field of fine chemical color masterbatch formula composition, in particular, the invention relates to a monochrome masterbatch composition for colored high-concentration polyolefin, which is mainly suitable for coloring polyethylene and polypropylene films or injection molded parts. Background technique [0002] Due to the direct coloring of toner in the plastic industry, there are problems such as poor dispersion, large dust, inaccurate measurement, serious color difference within and between batches, and poor color repeatability. The application of color masterbatch to replace toner in the plastics industry It is becoming more and more common, and the industry generally expects that the growth rate of color masterbatch output will be higher than that of the plastics industry. In recent years, with the rapid development of the plastics industry and economy, the application of color masterbatch has become more and more exte...

AI Technical Summary

Problems solved by technology

[0003] Polyolefin resin occupies more than half of the market in extrusion, injection molding, blow molding, blown film, casting, calendaring, wire drawing and other process applications, and the color masterbatch used in polyolefin occupies 2 / 3 of the color masterbatch market However, the current market share of color masterbatches in the color masterbatch market is less than 20%, and most of them are spot colors prepared by color masterbatch suppliers for specific colors for specific customers. The domestic market for color high-concentration monochrome masterbatches is completely blank
