The invention discloses a preparation method of a 3D printing-based magnetron tunable wave absorbing plate, in the field of wave absorbing materials, comprising the following steps: a. weighing a certain mass of magnetic particles, thermoplastic powder, reinforcing particles, anti-aging agent and Conductive powders, and blend and stir them at room temperature for 5 minutes to obtain mixed powders that can be used to prepare wave-absorbing wires; b. Add the mixed powders obtained in step a to the 3D printing wires consisting of an extruder, a water cooling system and a tractor. The preparation system is melted and blended, and processed by a water cooling system to obtain a magnetic wave absorbing wire; the 3D printing-based magnetron tunable wave absorbing plate of the present invention has the advantages of high absorption intensity, wide absorption frequency band, high production precision and tunability. . |
