ABS color masterbatch and preparation method thereof

Abstract

The invention discloses ABS color masterbatch and a preparation method thereof, and relates to the technical field of plastic coloring. The ABS color masterbatch comprises raw materials in parts by mass as follows: 30-70 parts of a carrier, 10-30 parts of toner, 5-40 parts of a dispersant, 0.1-2 parts of a heat stabilizer, 1-10 parts of a processing aid, 15-70 parts of filler, 10-30 parts of a flame-retardant modifier, 5-8 parts of an ultraviolet light absorber and 3-7 parts of an antistatic agent, wherein the carrier is prepared from acrylonitrile, 1,3-butadiene and styrene resin by mixing ina ratio of 2:1.2:5; the flame-retardant modifier is prepared from hard chlorinated polyethylene containing 42% of chlorine; the ultraviolet light absorber is prepared from o-t-butyl p-cresol, 4-chloro-2-nitroaniline, organosilicone modified acrylic resin, bisphenol A diglycidyl ether and acrylic polyol in a ratio of 0.2:0.5:2:0.7:1; the antistatic agent is one of monoglyceric stearate, polyethylene glycol oleate, polyoxyethylene, sorbitol and alkyl amide. The ABS color masterbatch not only has the advantages of stable color and small color difference, but also has the performance of impact resistance, flame retardance, static resistance and ultraviolet light resistance.

Description

technical field [0001] The invention relates to the technical field of plastic coloring, in particular to an ABS color masterbatch and a preparation method thereof. Background technique [0002] ABS resin is a terpolymer of acrylonitrile, butadiene and styrene, which can be produced by blending, copolymerization and emulsion grafting. By adjusting the composition of the three monomers in ABS, materials with various grades such as ultra-high impact resistance type, general type and special type (such as electroplating grade) can be prepared. The plastic products made of ABS materials are non-toxic, tasteless, and their rigidity and toughness can meet the requirements of household appliances, light industrial stationery, automobile industry and chemical industry, and are widely used. [0003] At present, many of the higher-end plastic accessories for household appliances are mainly made of ABS plastic. With the development trend of personalization and differentiation of hous...

Problems solved by technology

The toner coloring method is simple, but it has the disadvantages of easy to produce color points, difficult to control color difference, and great environmental pollution; dyeing and granule coloring is to mix ABS and toner and then use mixing equipment for melt blending to obtain colored powder. Compared with the coloring of toner, although the coloring effect is increased, it needs to be heated twice, which increases the production cost; masterbatch coloring is to pretreat the pigment and evenly disperse it in the carrier resin , which greatly improves the dispersibility and coloring rate of the pigment, and has the advantages of simple operation, low cost, and environmental friendliness.
