Example Embodiment

[0033] Example 1

[0034]

[0035] The matrix material of the composite material is PP slices, and the perylene fluorescent additive is a compound of crystalline formula (III).

[0036] The perylene fluorescent additive crystals dried in vacuum for 3 hours are ground in a ball mill to make it into a powder with a particle size of 10nm-100um. The pre-kneader adopts co-directional and non-directional occlusal rotation shafts to squeeze alternately, and kneading temperature It is 110°C. The kneaded product was dried in a vacuum with a vacuum of 10KPa and a temperature gradient. The drying temperature was 90°C and the total drying time was 10h. After being dried thoroughly, it is poured into twin-screw extrusion equipment, melted and extruded, and the conveying temperature is 190℃. After the melt is extruded, it is cooled into filaments by underwater drawing, and finally enters the pelletizer to be cut into pellets to obtain a fluorescent functional composite. Resin. The composite r...
