Beschreibung
Zusammenfassung:	The invention discloses a fire resistant glass fiber reinforced polyethylene terephthalate/polybutylece terephthalate (PET/PBT) alloy and a preparation method thereof. The PET/PBT alloy comprises the following components by weight percent: 10-42% of PBT, 10-42% of PET, 7-12% of halogen flame retardant, 3-5% of antimony (III) oxide, 3-10% of compatilizer, 0.3-0.9% of antioxidant, 0.5-1% of nucleation accelerator, 3-8% of composite nucleating agent, 10-30% of glass fiber and 0.4-1% of processing additive. PET and PBT are mixed together to prepare the PET/PBT alloy; the PET/PBT alloy has high crystallization rate, good mechanical propertics, high heat deflection temperature, high surface gloss, low shrinkage rate, stable dimension, low warpage and lower cost; and in some cases, the PET/PBT alloy of the invention can completely replace bakelite powder.
