Embodiment 1
[0021] First, under normal temperature and pressure, polyphenylene sulfide, polyurethane, compatibilizer, antioxidant, coupling agent, lubricant and carbon black are mixed evenly by high-speed stirring. The stirring speed is about 3000 rpm or more. The stirring time About 3 minutes. Then add glass fiber and wollastonite fiber, disperse evenly by stirring at a low speed, the stirring speed is about 200 rpm or less, and obtain a mixture. In this embodiment, in parts by weight, polyphenylene sulfide 35, glass fiber 40, polyurethane 30, wollastonite fiber 10, and additive 2.4. In parts by weight, compatibilizer 1, antioxidant 0.3, coupling agent 0.3, lubricant 0.4, carbon black 0.4.
[0022] Then, the mixed material is added into a twin-screw extruder, and the set process conditions of the twin-screw extruder are a temperature of 300-350° C. and a screw speed of 1100 rpm.
[0023] Finally, a cold water tank is set at the discharge port of the twin-screw extruder, and the extrude...
