Abstract

The invention discloses a color master batch applicable to a dairy packing material taking polystyrene as a base material. The color master batch comprises 100 to 120 parts of polystyrene, 60 to 80 parts of pigment, 1 to 5 parts of an antibacterial agent, 1 to 5 parts of a lubricant, and 0.6 to 1 part of a dispersant. A preparation process comprises material mixing, blending and extrusion granulation. The color master batch has the advantages that the polystyrene and the antibacterial agent are matched with each other, a polystyrene master batch has excellent antibacterial activity and high-barrier property, the machine-shaping property of the antibacterial agent, the polystyrene and the pigment is enhanced under the action of the lubricant and the dispersant, and meanwhile the antibacterial agent is not easy to emigrate, so that the formed polystyrene color master batch has lasting antibacterial activity after being machined into dairy package, and can enduringly protect the quality of dairy products; the added dispersant is beneficial to sufficient dispersion of the pigment, ensures that the pigment is conveniently adhered to a carrier, and the color is uniform.

Description

technical field [0001] The invention relates to a color masterbatch, in particular to a color masterbatch suitable for dairy product packaging materials with polystyrene as the base material. Background technique [0002] Masterbatch (English name Masterbatches) full name plastic masterbatch, alias masterbatch, is a kind of plastic processing aid developed and stood up in the 1980s. It is composed of excessive chemical additives, carrier resin and dispersant. composition. Masterbatch is an aggregate obtained by uniformly loading super-normal pigments (dye) in resin. Master batch means that in the process of plastic processing and molding, for the convenience of operation, the required various additives, fillers and a small amount of carrier resin are first mixed and kneaded, and then measured, mixed, melted and extruded by extruders and other equipment. The pellets produced by processing such as extruding and pelletizing are called master batches. Masterbatch is composed ...
