Zusammenfassung: | The invention relates to a PBT (polybutylene terephthalate) alloy material convenient for ultrasonic welding and a preparation method thereof, and the PBT alloy material comprises the following components in parts by weight: 70-85 parts of PBT resin, 10-20 parts of PC (polycarbonate) resin, 5-10 parts of glass fiber powder, 5-10 parts of plasticizer, 1-2 parts of compatilizer and 0.1-1 part of other auxiliaries. Compared with the prior art, the glass fiber powder is added into the prepared material, so that sound waves are more easily conducted to a bonding surface, and the energy loss of the sound waves is reduced; meanwhile, the PC and the plasticizer are added, so that the crystallization rate of the material is reduced, the impact resistance of the material is improved, the softening temperature of the material is reduced, the material is easier to bond, and the problem of cracking of a bonding surface is avoided.
