Abstract

The invention provides a composition of flame-retardant polycarbonate and acrylonitrile-butadiene-styrene resin. The composition comprises the following components and weight percentage (based on the total weight of the composition): 40 to 80 percent of polycarbonate, 5 to 45 percent of acrylonitrile-butadiene-styrene resin, 5 to 40 percent of halogen-free main flame retardant and 1 to 5 percent of boron-containing auxiliary flame retardant. The composition of flame-retardant polycarbonate and acrylonitrile-butadiene-styrene resin can not emit a large amount of dense smoke, corrosive gas or toxic gas during combustion, and improves the processability of materials.

Description

technical field [0001] The invention belongs to the field of polymer modification, in particular to a flame-retardant polycarbonate and acrylonitrile-butadiene-styrene thermoplastic resin composition. Background technique [0002] Polycarbonate (PC) is an amorphous thermoplastic engineering plastic with excellent comprehensive mechanical, electrical and heat resistance properties, especially known for its excellent impact strength and creep resistance. Polycarbonate itself and its blends (or alloys) with other polymers, especially the composition of acrylonitrile-butadiene-styrene, are widely used in electronics, electricity, machinery, automobiles, aerospace, construction, Office and many other fields. [0003] Household appliances and office supplies require heat resistance and flame retardancy, and halogenated flame retardants are usually added for flame retardancy. For example, US4810739 discloses a kind of flame retardant comprising aromatic polycarbonate, acrylonitri...
