High-dispersion flame-retardant ABS color masterbatch and preparation method thereof

Abstract

The invention discloses high-dispersion flame-retardant ABS color masterbatch. The color masterbatch is prepared from the following raw materials in parts by weight: 40-60 parts of polystyrene, 20-30parts of an inorganic pigment, 4-6 parts of a composite dispersant, 10-15 parts of fibers, 6-9 parts of a magnesium hydroxide flame retardant, and 0.1-1 part of a filler. The ABS color masterbatch provided by the invention has good dispersibility and flame retardance, low processing costs and a simple preparation process; the bamboo charcoal fibers are added, so that the antibacterial rate is up to 90% or more, the ultraviolet transmittance is low, and the anti-aging performance is strong; and when the color masterbatch is applied to coloring of an ABS product, the color masterbatch has the advantages of uniform coloring, good flame retardance, good antibacterial performance, high color stability, small color difference and no influence on mechanical properties of the plastic product.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-dispersion flame-retardant ABS color masterbatch and a preparation method thereof. Background technique [0002] ABS resin is a terpolymer of acrylonitrile, butadiene and styrene. At present, its production methods include blending method, copolymerization method and emulsion grafting method. By adjusting the ratio of the three monomers, resins with different properties and brands can be prepared, such as high impact resistance type, general purpose type and special type, etc. ABS is non-toxic, odorless, tough, hard, and rigid, easy to form, and has excellent comprehensive performance. It is widely used in household appliances, light industrial stationery, automobile industry, and chemical industry. However, when the masterbatch with ABS as the carrier is used for coloring, due to the poor fluidity of the carrier, problems such as flow lines, uneven ...

AI Technical Summary

Problems solved by technology

However, when the masterbatch with ABS as the carrier is used for coloring, due to the poor fluidity of the carrier, problems such as flow lines, uneven color, and difficult control of color difference are prone to occur.

[0003] At present, domestic masterbatch products have a single structure and incomplete varieties, and general-purpose products account for a large proportion. When plastics need to be colored, single-color masterbatches are used for coloring. When antistatic performance is required, antistatic masterbatches are added. When flame retardant performance is required Add flame retardant masterbatch

The method of adding a single masterbatch makes it necessary to add a variety of color masterbatches with different functions when the comprehensive performance of the carrier resin is high, thus consuming a large amount of carrier resin and resulting in the consumption of antioxidants during processing Due to the disadvantages of high volume, many components in downstream molding processing, and complicated processes, the future masterbatch will continue to develop in the direction of multi-functionality, high color content and high technology content.
