Abstract

The invention discloses a black master batch applied to a multipolymer (AS series plastic) containing acrylonitrile and styrene and a preparation method thereof. The black master batch consists of an acrylonitrile-styrene multipolymer, acetyl tri-n-butyl citrate, ethylene bis stearamide and a black pigment. Partial acrylonitrile-styrene multipolymer, the acetyl tri-n-butyl citrate and the ethylene bis stearamide are subjected to melting and banburying in a banbury mixer evenly, the black pigment is added, the mixture is subjected to banburying and dispersed evenly as well as cooled and crushed, and the mixture is mixed with the remaining acrylonitrile-styrene multipolymer and is extruded and granulated on a twin screw. The produced black master batch is easy to disperse in the AS series plastic, the process equipment requirement of the subsequent coloration of the plastic product is reduced, the equipment efficiency is improved, the coloured plastic product has even color, no color difference and high lustrousness.

Description

technical field

[0001] The invention relates to a color masterbatch used in plastic processing, in particular to a color masterbatch containing copolymers of acrylonitrile and styrene (AS series plastics) and a preparation method thereof. Background technique:

[0002] AS series plastics include acrylonitrile-styrene copolymer (AS plastic), acrylate-acrylonitrile-styrene copolymer (AAS resin), graft copolymer of EPDM rubber with styrene and acrylonitrile (AES resin ), acrylonitrile-butadiene-styrene copolymer (ABS resin), methyl methacrylate-acrylonitrile-butadiene-styrene copolymer (transparent ABS resin or MABS resin), etc., usually using PS color It is difficult to disperse PS color masterbatch in AS plastic. In order to fully disperse the color masterbatch, it is necessary to increase the shear force of the mixing machine and increase the mixing time, thus increasing energy consumption and reducing work efficiency.
