| titleOfInvention | Broadband electromagnetic wave absorbing material and preparation method thereof |
| abstract | The invention relates to a broadband electromagnetic wave absorbing material and a preparation method thereof, which are characterized in that the total thickness of the material is less than or equal to 4.00mm, and the material has a double-layer structure; the first layer of the electromagnetic wave absorbing material comprises unreduced carbonyl iron powder and high molecular polymer, the thickness of the first layer is 0.60-1.00 mm, and the mass ratio of the first layer to the second layer is as follows: 85-93% of unreduced carbonyl iron powder and 7-15% of polymer; the second layer of the electromagnetic wave absorption material comprises reduced carbonyl iron powder and a high molecular polymer, the thickness of the second layer is 2.00-3.40 mm, and the mass ratio of the second layer of the electromagnetic wave absorption material is as follows: 33-70% of reduced carbonyl iron powder and 30-67% of polymer. The invention has the beneficial effects that: the broadband electromagnetic wave absorbing material has the advantages of thin thickness, wide absorbing frequency band and large absorbing capacity, is easy to obtain raw materials, simple in production process and low in cost, and is suitable for large-scale production. |
