Embodiment 1
[0025] Take by weighing 60 parts of PVDF resin, 0.3 part of antioxidant 1010, 0.1 part of antioxidant 168, 0.1 part of lubricant EBS and mix them at room temperature for 5 minutes in a high mixer, then add them to a twin-screw extruder and extrude, and the resulting melt is obtained from The melt inlet of the impregnation equipment is extruded into the impregnation tank of the impregnation equipment;
[0026] Continuous carbon fiber (Japan Toray Company, brand T300) is introduced from the fiber entrance of impregnation equipment, enters the surface treatment chamber of impregnation equipment, and the weight content of control surface treatment agent silane coupling agent KH560 relative to carbon fiber is 1%, then The carbon fiber treated with the surface treatment agent is introduced into the impregnation tank of the impregnation equipment to realize the dispersion of carbon fiber and compound with PVDF resin; by selecting the size of the shaping die (2mm) and adjusting the mai...
Embodiment 2
[0029] Take by weighing 80 parts of PVDF resin, 0.5 part of antioxidant 1098, 0.2 part of antioxidant 168, 0.3 part of lubricant calcium stearate and mix them at room temperature in a high mixer for 3 minutes, then add them to a twin-screw extruder and extrude them. The melt is extruded from the melt inlet of the impregnation equipment into the impregnation tank of the impregnation equipment;
[0030] The continuous carbon fiber (Toray Corporation, Japan, brand T300J) is introduced from the fiber inlet of the impregnation equipment, and enters the surface treatment chamber of the impregnation equipment, and the surface treatment agent titanate coupling agent isopropyl triisodecanoyl titanate is controlled. The weight content relative to the carbon fiber is 2%, and then the carbon fiber treated by the surface treatment agent is introduced into the dipping tank of the dipping equipment to realize the dispersion of the carbon fiber and compound it with PVDF fat; by selecting the s...
Embodiment 3
[0033] Weigh 90 parts of PVDF resin, 0.3 part of antioxidant 1098, 0.1 part of antioxidant 168, 0.6 part of lubricant stearic acid and mix them at room temperature for 5 minutes in a high-mixer, then add them to a twin-screw extruder and extrude them. The body is extruded from the melt inlet of the impregnation equipment into the impregnation tank of the impregnation equipment;
[0034] The continuous carbon fiber (Japan Toray Company, brand T700S) is introduced from the fiber inlet of the impregnation equipment, enters the surface treatment chamber of the impregnation equipment, and controls the surface treatment agent aluminate coupling agent distearoyloxyisopropyl aluminate The weight content relative to the carbon fiber is 3%, and then the carbon fiber treated by the surface treatment agent is introduced into the dipping tank of the dipping equipment to realize the dispersion of the carbon fiber and compound it with PVDF resin; by selecting the size of the shaping die (5mm)...
