Environment-friendly regenerated PET modified PC/ABS alloy and preparation method thereof

The invention relates to the technical field of recycled plastic utilization, in particular to an environment-friendly recycled PET modified PC/ABS alloy and a preparation method thereof.The environment-friendly recycled PET modified PC/ABS alloy is prepared from, by weight, 20-30 parts of marine recycled PET, 12-18 parts of recycled ABS, 25-45 parts of recycled PC, 1-3 parts of SAN resin, 1-5 parts of compatilizer, 3-7 parts of flexibilizer, 2-6 parts of filler, 0.5-1.5 parts of chain extender, 3-7 parts of flame retardant and 1-3 parts of antioxidant. According to the PC/ABS alloy disclosed by the invention, regenerated ABS and regenerated PC are taken as matrixes, and marine recycled PET and various auxiliaries are added, so that the alloy with good mechanical strength, flowability, flame retardance and high and low temperature resistance is formed, and the PC/ABS alloy can be used for shells of products such as electric appliances, has relatively good practical prospects and obvious social and economic be
