Abstract

The invention discloses a transparent high-hardness impact-resistant acrylonitrile butadiene styrene (ABS) plastic alloy composition. The transparent high-hardness impact-resistant ABS plastic alloy composition comprises 30 to 50 weight parts of styrene-acrylonitrile resin, 30 to 50 weight parts of polymethacrylate resin and 10 to 30 weight parts of acrylic ester elastomer. The ABS plastic alloy composition prepared by the technical scheme has the advantages that: the ABS plastic alloy composition is transparent and has high toughness and high surface hardness; 2, the ABS plastic alloy composition is transparent and has high impact resistance and surface hardness, so surface coating can be saved; and 3, the ABS plastic alloy composition has high flowability, so filling formation of a large-sized die is facilitated. The ABS plastic alloy composition can be applied to shells of mobile phones, mobile digital video disc (DVD) electronic products, domestic appliances such as televisions, liquid crystal displays and the like and automobile instrument displays and the like.

Description

technical field [0001] The invention relates to an ABS plastic alloy composition, in particular to a transparent, high-strength, impact-resistant ABS plastic alloy composition, which belongs to the field of polymer materials. Background technique [0002] The light transmittance of the transparent ABS material can reach more than 85%, and its mechanical strength exceeds that of the same transparent MBS resin. At the same time, transparent ABS has excellent impact strength and notched impact strength, and even low temperature impact resistance is also very good; it also has high bending strength and surface hardness. Compared with other transparent resins (such as the fluidity of PC, the chemical stability of PMMA, and the impact resistance of SAN), transparent ABS has obvious advantages, so that transparent ABS is unique in new application fields. [0003] At present, the production process of transparent ABS is mainly emulsion grafting or bulk polymerization method, that i...
