Abstract

The invention discloses a universal high-gloss black masterbatch. The universal high-gloss black masterbatch comprises the following components in percentage by weight: 20-60% of carbon black and / or solvent black, 10-75% of polyethylene, 5-50% of a transparent resin and 4-40% of an additive. The universal high-gloss black masterbatch disclosed by the invention is suitable for most plastics including the polyolefin plastic, the styrene copolymer plastic, the polyester plastic and the polyamide plastic, has good dispersibility and high gloss and can be less affected by the mechanical properties of a colored resin.

Description

technical field [0001] The invention relates to the field of plastic coloring, in particular to a general-purpose high-gloss black masterbatch. Background technique [0002] Color masterbatch is an aggregate obtained by uniformly loading super-normal pigments or dyes in resin, also known as pigment concentrate. According to the statistics of China Masterbatch Committee: In 2011, the national output of masterbatch exceeded 650,000 tons. 40% of them are black masterbatches. Black masterbatches are widely used in agriculture, packaging, construction and decoration, automobiles, machinery, home appliances, post and telecommunications and other fields. [0003] At present, most of the black masterbatches are special and color masterbatches with the same or similar resin as the carrier; or general-purpose black masterbatches with polyethylene as the carrier. Special black masterbatches such as: patent CN200610030033.6 discloses black masterbatches for polyethylene pipes for wat...
