Embodiment 1
[0021] 40kg polyphenylene ether (PPO), 40kg polyamide 6 (PA6), 0.3kg antioxidant 1010, 0.3kg coupling agent γ-glycidyl etheroxypropyl trimethoxysilane (KH560), 3kg compatibilizer horse Anhydride-grafted polystyrene graft (PS-g-MAH), 1kg lubricant silicone powder and 5kg filler talcum powder were added to a high-speed mixer and mixed evenly at high speed, then 20kg polyvinyl alcohol fiber was added to mix evenly at a low speed, and then extruded through a twin-screw Melting, kneading, extruding, cooling, drying, pelletizing. The temperature of each zone of the barrel of the twin-screw extruder used is kept between 230 and 260°C.
Embodiment 2
[0023] 40kg polyphenylene ether (PPO), 38kg polyamide 6 (PA6), 0.3kg antioxidant 1010, 0.3kg coupling agent γ-glycidyl etheroxypropyl trimethoxysilane (KH560), 3kg compatibilizer horse Anhydride-grafted polystyrene graft (PS-g-MAH), 1kg lubricant silicone powder and 5kg filler talc powder are added to a high-speed mixer and mixed evenly at high speed, then 22kg polyvinyl alcohol fiber is added to mix evenly at a low speed, and then extruded through a twin-screw Melting, kneading, extruding, cooling, drying, pelletizing. The temperature of each zone of the barrel of the twin-screw extruder used is kept between 230 and 260°C.
Embodiment 3
[0025] 40kg polyphenylene ether (PPO), 35kg polyamide 6 (PA6), 0.3kg antioxidant 1010, 0.3kg coupling agent γ-glycidyl etheroxypropyl trimethoxysilane (KH560), 3kg compatibilizer horse Anhydride-grafted polystyrene (PS-g-MAH), 1kg lubricant silicone powder and 5kg filler talc powder were added to a high-speed mixer and mixed evenly at high speed, and then 25kg polyvinyl alcohol fibers were added to mix evenly at a low speed and then extruded through a twin-screw Melting, kneading, extruding, cooling, drying, pelletizing. The temperature of each zone of the barrel of the twin-screw extruder used is kept between 230 and 260°C.
