High-gloss scratch-resistant chemical-resistant PC/polyester alloy material and preparation method thereof

The invention relates to the field of polymer materials, particularly a high-gloss scratch-resistant chemical-resistant PC/polyester alloy material. The material is prepared from the following components in parts by weight: 10 to 60 parts of PC resin, 10 to 40 parts of polyester, 1 to 10 parts of a toughening agent, 1 to 50 parts of scratch-resistant masterbatch, 0.1 to 5 parts of a wear-resistantauxiliary agent, 0.1 to 1 part of an antioxidant and 0.1 to 1 part of a lubricant. The invention also provides a preparation method of the PC/polyester alloy. According to the invention, the scratch-resistant masterbatch and the wear-resistant auxiliary agent are added into the PC/polyester alloy; and an instant-cooling and instant-heating injection molding process is used in the injection molding process, so that the high-gloss spraying-free part can be prepared, and meanwhile, the high-gloss spraying-free part has excellent scratch resistance and chemical resistance, and can be used as an automotive interior part,
