Cement-based electromagnetic wave impedance matching material and preparation method therefor
The present invention discloses a cement-based electromagnetic wave impedance matching material and a preparation method therefor, and belongs to the cross technical field of electromagnetics and material science. The material is prepared from common silicate cement, expanded perlite, ceramic waste, a water reducing agent and water in a certain proportion by weight. The obtained product has relatively high wave transmissivity within a range of 8.2-12.4 GHz and 12-18 GHz, wherein within the range of 8.2-12.4 GHz, a maximum value of the wave transmissivity is close to 90%. The cement-based electromagnetic wave impedance matching material uses the ceramic waste as a raw material, increases the utilization rate of the ceramic waste and improves the environment. The cement-based electromagnetic wave impedance matching material is low in production cost; and the preparation method for the cement-based electromagnetic wave impedance matching material is simple. Compared with a double-layer cement-based wave absorbing material that is prepared from common wave absorbing materials in a composite mode, a wave absorbing material prepared from the material disclosed by the present invention is obviously better in wave-absorbing capacity and absorption bandwidth, so that an impedance matching material that is good in wave-absorbing capacity and low in production cost is provided for common wave absorbing materials.
