Problems solved by technology

[0002] Traditional coloring generally uses a single pearlescent powder for coloring, or pearlescent coloring masterbatch for coloring, but the toner coloring method has been gradually replaced by masterbatch due to the long processing cycle, inconvenient color change, and environmental pollution. However, the existing color masterbatch has a single function, and in the process of processing, it is easy to destroy the inner structure of the color masterbatch

Abstract

The invention discloses a macromolecule color masterbatch which is composed of the following components in percentage by weight: a, 30-60% of carrier resin, b, 5-15% of pigment, c, 4-8% of dispersed lubricant, d, 1-3% of compatilizer and e, 15-25% of other additives. The component e comprises an antistatic agent, a protective agent, a heat stabilizer and an antibacterial agent. The preparation method comprises the following steps of: mixing each component in proportion and placing the mixture in a high-speed mixer; secondly, mixing for 5-20 minutes at the rotate speed of 1000-1500r / min (revolutions per minute); thirdly, carrying out melt blending by adopting a double-screw extruder or an internal mixer as the temperature is at 150-250 DEG C; and fourthly, shearing and mixing by a screw or a rotor as the rotate speed of the screw is 80-300r / min, finally extruding in the extruder, cooling, drying and pelleting to prepare the color masterbatch. The macromolecule color masterbatch has the advantages of anti-static electricity, invariant color, no color loss and uniform color and luster, and the process is clean and environmentally-friendly.

Description

Technical field [0001] The invention relates to a polymer masterbatch and a preparation method thereof. Background technique [0002] Traditional coloring generally uses a single pearlescent powder for coloring, or uses a pearlescent coloring masterbatch for coloring. However, due to the long processing cycle, inconvenient color change, and environmental pollution, the toner coloring method has gradually been replaced by masterbatch. However, the existing masterbatch has a single function, and it is easy to destroy the internal structure of the masterbatch during processing. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a polymer masterbatch with the advantages of antistatic, no discoloration, no loss of gloss and uniform color, and a clean and environmentally friendly processing process and a preparation method thereof. [0004] The present invention is realized through the following technical solutions: a new type of p...
