The invention discloses a PC/PBT alloy material, which, in parts by weight, comprises components: 67.6-88.5 parts of PC resin; 9-22 parts of PBT resin; ethylene-butyl acrylate-methyl methacrylate copolymer 2 ~8 parts; 0.45~2.2 parts of compatibilizer; 0.05~0.2 parts of transesterification inhibitor. By controlling the content of PBT in the PC/PBT alloy, and simultaneously selecting and adding ethylene-butyl acrylate-methyl methacrylate copolymer, compatibilizer and transesterification inhibitor, the present invention can significantly improve PC/PBT by cooperating with each component. Ultrasonic welding effect of PBT alloy material, the prepared PC/PBT alloy material has good ultrasonic weldability, high welding strength, and can significantly reduce the stress concentration and material damage in the welding part, and the usability of ultrasonic welding products High, further broaden the application of PC/PBT alloy materials. |
