The present invention discloses a high-strength polyphenylene sulfide-based plastic and its preparation method, falling within the technical field of polyphenylene sulfide-based plastics. It comprises the following components in weight parts: polyphenylene sulfide 100 parts, nylon 35-50 parts, fiber component 25-35 parts, compatibilizer 5-10 parts, lubricant 1-3 parts; The preparation steps are as follows: Dry the polysulfone, polyamide, and compatibilizer in an oven at 110–130°C for 6–8 hours. Weigh the raw materials according to the above formulation and place them in a mixer. After mixing for 5–10 minutes, transfer the mixture to a twin-screw extruder. Melt extrusion and pelletization can then be performed at an extrusion temperature of 280–310°C. Addressing the inherent issues of poor weather resistance and mechanical strength in existing polysulfone-based plastics, this invention introduces a proprietary fiber component. This innovation endows polysulfone-based plastics with enhanced weather resistance while maintaining their excellent mechanical strength, simultaneously overcoming problems associated with conventional antioxidants such as migration, precipitation, and instability.
