Example Embodiment

[0011] The present invention will be further described below in conjunction with embodiments:

[0012] First, the weighed polybutylene terephthalate (PBT) and polyhexamethylene terephthalamide (PA6T) are dried at 120°C for 4 hours. Pour the dried polybutylene terephthalate and polyhexamethylene terephthalamide into a high-speed mixer and stir at low speed. While stirring, put all the components except magnesium sulfate whiskers into a high-speed mixer according to the ratio in Table 1 and mix for 10 minutes. Then blended and extruded through a twin screw extruder. Magnesium sulfate whiskers are forcibly added through side feeding. The blending processing temperature is 245-260°C, the screw speed is 350r / min, and the product is extruded, water-cooled, and pelletized. The produced material was dried at 120°C for 4 hours, and then a standard mechanical property test specimen was prepared on an injection molding machine. The injection pressure is 60-90Mpa, the barrel temperature i

Abstract

The invention relates to the field of organic polymer, in particular to a poly-terephthalic acid butanediol ester (PBT)/ poly-terephthaloyl hexamethylenediamine (PA6T) alloy material capable of enhancing inflaming retarding and a production method thereof. PBT, PA6T, magnesium sulfate whisker, compatilizer, DBDPE, fire retardant antimonous oxide, fire retardant tripolycyanamide urate and antioxygen are adopted as raw materials and are dried, mixed, extruded and cut into particles so that the magnesium sulfate whisker inflaming retarding enhancing PBT/PA6T alloy material is produced. The PBT/PA6T alloy material capable of enhancing the inflaming retarding and the production method thereof are characterized in that weight percentage of composition of the raw materials comprises: the 40%-45% of PBT, the 5%-10% of PA6T, the 22%-30% of magnesium sulfate whisker, the 5%-8% of compatilizer, the 6%-10% of DBDPE, the 3%-5% of fire retardant antimonous oxide, the 3%-5% of fire retardant tripolycyanamide urate and the 0.3%-0.5% of antioxygen. The PBT/PA6T alloy material capable of enhancing the inflaming retarding and the production method thereof have the advantages that the magnesium sulfate whisker inflaming retarding enhancing PBT/PA6T alloy material produced is good in liquidity, high in glowing filament performance and mechanical property and simple in production technology.
