Embodiment 1
[0015] First bake 40% by weight of PA6 resin at 120°C for 3 hours to control the moisture below 0.1%; then mix with 18% by weight of brominated polystyrene, 6% by weight of antimony trioxide and 5% by weight of zinc borate, 0.1% by weight of primary antioxidant tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate) pentaerythritol ester (1010) and 0.2% secondary antioxidant tris(2,4-di tert-butylphenyl) phosphite (168), other processing aids of 0.7% by weight are mixed by a high-speed mixer for 2 minutes and then enter the twin-screw extruder from the metering feeder to be plasticized and melted. 30% by weight of alkali-free glass fiber is added into the extruder, and then the product is obtained through extrusion, cooling, magnetization and packaging.
Embodiment 2
[0017] First bake 35% by weight of PA6 resin at 120°C for 3 hours to control the moisture below 0.1%; then mix with 15% by weight of brominated polystyrene, 5% by weight of antimony trioxide, 9% by weight of zinc borate, 0.1% by weight of primary antioxidant tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate) pentaerythritol ester (1010) and 0.2% secondary antioxidant tris(2,4-di tert-butylphenyl) phosphite (168), 0.7% by weight of other additives are mixed by a high-speed mixer for 2 minutes, and then enter the twin-screw extruder from the metering feeder to be plasticized and melted. 35% by weight of alkali-free glass fiber is added into the machine, and then the product is obtained through extrusion, cooling, magnetic passing and packaging.
