Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a flame-retardant PC / ABS composite, a preparation method and application thereof. Background technique [0002] PC / ABS alloy is an alloy material synthesized by PC (polycarbonate) and ABS (acrylonitrile-butadiene-styrene copolymer) in a certain proportion. Polycarbonate (PC) has the advantages of high impact strength, creep resistance, good dimensional stability, heat resistance, transparency, and excellent dielectric properties, but it also has poor processing fluidity, prone to stress cracking, sensitive to notches, and Disadvantages such as poor abrasiveness; acrylonitrile / butadiene / styrene copolymer (ABS) has good chemical resistance and molding processability, but its heat resistance and weather resistance are relatively poor. The PC / ABS alloy obtained by blending and modifying the two can complement each other in performance. Not only the heat resistance, impac...
