Beschreibung
Zusammenfassung:	The invention discloses a glass fiber enhanced PET/PBT (Polyethylene Terephthalate)/(Polybutylene Terephthalate) alloy with high glossiness and low warping degree and a preparation method thereof. The PET/PBT alloy comprises the following components by mass percentage content: 15-60% of PBT, 19-60% of PET, 3-10% of compatilizer, 0.3-0.9% of antioxygen, 0.5-1% of nucleating accelerating agent, 3-8% of composite nucleating agent, 10-30% of glass fiber and 0.4-1% of processing aid. According to the invention, the PET and the PBT are fused to obtain the PET/PBT alloy, and the PET/PBT alloy has the advantages of quick crystallizing speed rate, good physical performance, high distortion temperature, high surface glossiness, low contractibility rate, stable dimension, low warping degree and lower cost; and the PET/PBT alloy of the invention can be used for completely replacing the bakelite powder under a specific occasion.
