Abstract

The invention belongs to the technical field of plastic coloring, and discloses high-lightness and high-brightness black masterbatch and a preparation method thereof. The high-lightness and high-brightness black masterbatch comprises components in percentage by weight as follows: 40%-45% of carbon black, 48%-55% of carrier resin, 4%-10% of hyperdispersant and 0.5%-2% of a high-temperature stabilizing agent. The preparation method comprises steps as follows: the carbon black, the carrier resin, the hyperdispersant and the high-temperature stabilizing agent are prepared according to content of a formula, the components of raw materials are totally put in a low-speed mixer for pre-mixing treatment, and then the obtained mixture is transferred to a pressurizing mixer for pressurizing mixing; materials obtained through pressurizing mixing are sliced and placed in a double-roll extruding machine for extrusion forming; materials obtained through extrusion are broken and transferred into a spiral granulator for granulation; and obtained materials are cooled, dried and sub-packaged to obtain the high-lightness and high-brightness black masterbatch. The high-lightness and high-brightness black masterbatch has high carbon black content, high blackness degree and good dispersity.

Description

technical field [0001] The invention belongs to the technical field of plastic coloring, and in particular relates to a high-gloss black masterbatch and a preparation method thereof. Background technique [0002] In the coloring process of engineering plastics, the usual process is to use toner (such as carbon black powder) in proportion to directly mix with engineering plastics for extrusion granulation, or injection molding into products. Due to the problems of poor dispersion and inaccurate measurement in the direct coloring of toner, it will cause the surface gloss of the processed plastic products to be poor, and there will be serious color differences between batches; Environmental pollution is serious. [0003] In recent years, the use of color masterbatch instead of toner for coloring has become more and more common. The application of color masterbatch has become more and more extensive. The research and development and production of new color masterbatch products ...
