Impact-resistant ABS (Acrylonitrile Butadiene Styrene) resin composite plastic, preparation method thereof and microphone made of plastic

The invention relates to the technical field of microphone production, and particularly discloses an anti-impact ABS (Acrylonitrile Butadiene Styrene) resin composite plastic, a preparation method of the anti-impact ABS resin composite plastic and a microphone made of the anti-impact ABS resin composite plastic. The impact-resistant ABS resin composite plastic comprises the following raw materials in parts by weight: 70-100 parts of ABS resin, 5-15 parts of thermoplastic polyurethane, 20-38 parts of a modifier and 3-7 parts of an auxiliary agent, the modifier comprises a flexibilizer, a filler and a plasticizer, and the weight ratio of the flexibilizer to the filler to the plasticizer is (7-15): (10-20): 3; the preparation method comprises the following steps: uniformly mixing the ABS resin, the thermoplastic polyurethane, the modifier and the assistant, and melting and granulating the mixture by a screw extruder to obtain the composite plastic. The impact-resistant ABS resin composite plastic can be used for
