Description

technical field [0001] The invention relates to the field of polymer alloy materials, in particular to a polycarbonate / acrylonitrile-butadiene-styrene / polypropylene ternary alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (Polycarbonate referred to as PC). It is a colorless and transparent amorphous thermoplastic material, which has the advantages of high impact strength, creep resistance, good dimensional stability, heat resistance, non-toxicity, and good dielectric properties. It is widely used in electronic appliances, automobiles, medical equipment, It is widely used in the fields of machinery, construction and lighting appliances, and has become an important member of the five major engineering plastics. However, pure PC resin also has disadvantages such as poor processing fluidity, easy stress cracking, sensitivity to notch, easy aging and poor wear resistance, which limit its application in certain fields. [0003] Acrylon...
