Problems solved by technology

However, using the high-gloss BaSO 4 The technology of filling modified ABS is not yet mature, BaSO 4 Directly filled into ABS resin, because the compatibility between inorganic particles and ABS resin is too poor, BaSO 4 The powder cannot be evenly dispersed into the resin, resulting in a great decline in the performance of the ABS resin, and also has a negative impact on the processing performance of the material

Abstract

The invention discloses an ABS (Acrylonitrile-Butadiene-Styrene) highlight packing master batch and a preparation method thereof. The ABS highlight packing master batch is prepared from the following raw materials in parts by weight: 0.5-2 parts of surface treatment agent, 60-90 parts of barium sulfate, 0.5-2 parts by weight of active agent, 0.5-2 parts by weight of dispersing agent, 3-12 parts by weight of lubricating agent, 0-8 parts by weight of compatilizer, 0-5 parts by weight of toughening agent, 0-2 parts by weight of antioxidant and 3-20 parts by weight of carrier resin. Compared with the prior art, the ABS highlight packing master batch has the advantages that multiplayer coating activating treatment is carried out on the inorganic particle barium sulfate, so that a layer of elastic compatilizer layer is formed on the surface of the barium sulfate, can generate strong bonding force with the barium sulfate and can also be bonded with the carrier resin through chemical bonds or strong van der waals force, thus the multilayer coating inorganic particles can be uniformly dispersed to the matrix resin, and when the material is subjected to external force action, the elastic compatilizer layer has good effects of buffering and stress dispersion and improves the toughness and anti-impact property of the material.

Description

technical field [0001] The invention relates to the technical field of masterbatches, in particular to an ABS highlight filler masterbatch and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene (abbreviated as ABS) resin is a general-purpose thermoplastic engineering plastic gradually developed in the 1940s. It is a plastic product with excellent comprehensive mechanical properties. It not only has good rigidity, hardness and processing fluidity , and has the characteristics of high toughness, can be extruded, injected or thermoformed, and is widely used in the fields of automobiles, electronic appliances and building materials. Among them, because ABS resin has the characteristics of impact resistance, sound insulation, heat resistance and scratch resistance, it is more beautiful than polypropylene (PP), and is especially suitable for parts with strict lateral impact resistance and service temperature. At present, ABS resin is the t...
