Embodiment 1
[0027]The control total amount is 1000g, by mass percentage (recorded as wt%), with 87.5wt%PBT, 9wt% aluminum diethylphosphinate, 3wt% side group band epoxy polysiloxane (PPM1), 0.2wt% Antioxidant B215 and 0.3wt% anti-dripping agent FA-500 were added to a high-speed mixer, and after stirring and mixing at room temperature, the resulting premix was melted, kneaded, extruded, cooled, pelletized and processed by a twin-screw extruder. dry. The model of the twin-screw extruder used is LTE26 / 40 (LabTech, Germany), and the temperature of each zone of the screw barrel is: the first zone: 160°C, the second zone: 225°C, the third zone: 230°C, and the fourth zone : 230℃, the fifth zone: 230℃, the sixth zone: 230℃, the seventh zone: 230℃, the eighth zone: 230℃, the ninth zone: 230℃, the machine head: 225℃, the feeding speed: 25r / min, host speed: 150r / min. The prepared pellets were injection-molded into standard specimens for testing according to the standard size, and the mechanical p...
