Description

technical field [0001] The invention belongs to the technical field of plastic alloys, in particular to a PC / PBT alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (PC, Polycarbonate) resin is a non-crystalline thermoplastic polymer with high impact strength, good rigidity, high heat resistance, good gloss, good dimensional stability, electrical insulation and excellent creep resistance , but its processing fluidity is poor and it is not resistant to organic solvents. [0003] Polybutylene Terephthalates (PBT, Polybutylene Terephthalates) is a crystalline polyester material with good fluidity, easy processing, and good resistance to organic solvents, but its impact strength is not high, poor dimensional stability, heat resistance, etc. deficiencies. [0004] The alloy material formed by PC / PBT combines the excellent properties of PC and PBT, such as the high impact resistance and dimensional stability of PC and the fluidity of PBT,...
