The invention discloses a modified regenerated ABS nanocomposite material, a preparation method and application thereof, and belongs to the technical field of regenerated ABS composite materials. The composite material includes a disperse phase that is uniformly dispersed in the base material with recycled ABS as the base material, and auxiliary materials that improve the mechanical properties of the base material. The preparation method is as follows: pretreating the recycled ABS, then mixing with the disperse phase and auxiliary materials, putting the mixture into an extruder for melting and extruding, granulating after cooling, and drying the granules to prepare a wire with a diameter of 1.75 mm , you can. Compared with the recycled ABS material, the modified regenerated ABS nano-composite material prepared by the invention has improved tensile strength, elongation at break, impact strength, flexural strength, flexural modulus and light transmittance, and has good flexibility 3D printing using the recycled composite material, the printing is smooth, odorless, and the printed product has the advantages of smooth surface, symmetrical, stable size, and not easy to shrink. |
