Example Embodiment
[0022] The specific implementation of the present invention is:
[0023] Step 1. Add 50-80 parts by weight of PC, 10-40 parts of PET, 3-10 parts of minerals, 1-3 parts of compatibilizer, and 0.2-1 parts of antioxidant into the extruder by weight to form Homogeneous mixture
[0024] Step two, adjust the temperature of the extruder to 240-270°C, convert the mixture obtained in step one into a molten state, knead and extrude the mixture, and perform granulation to obtain the heat-resistant and solvent-resistant PC / PET modified resin .
Example Embodiment
[0025] Implementation mode 1:
[0026] Add PC, PET, minerals, compatibilizers, and antioxidants to the mixer to disperse evenly, then add the mixture to the extruder, adjust the temperature of the extruder to 240-270°C to convert the mixture into a molten state. The mixture is kneaded, extruded, and pelletized to obtain a heat-resistant and solvent-resistant PC / PET modified resin.
