Example Embodiment
[0019] Example 1
[0020] A diagonal flow fan blade which is injection molded from the following materials in terms of mass percentage:
[0021]
[0022] The above-mentioned preparation method of diagonal flow blades, the method includes the following steps: mixing PP resin, mica, silane coupling agent DB792, and silane coupling agent kh560 in a high-mixer for 10-15 minutes; place in a twin-screw extruder Add glass fiber, carbon fiber and other additives from the side feed port to the main feed port for melt extrusion. After cooling in the water tank, the pellets are cut, then dried and mixed to obtain injection pellets; the pellets are fed into the injection molding machine The diagonal flow fan blade is obtained by injection molding in the process.
