This paper mainly introduces the harm of electromagnetic radiation pollution, and based on the electromagnetic wave absorption theory, the microwave absorption performance of single-layer microwave absorbing coating with magnesium oxysulfide cementitious material as matrix material and iron tailings as microwave absorbing agent is studied. The experimental results show that the absorbing effect of the absorbing coating mixed with 0.5 proportion iron tailings is the best, and the absorbing performance increases obviously with the increase of thickness. The maximum absorption value of 3mm thick coating sample is - 6.0 dB. The prepared microwave absorbing coating has certain application value in electromagnetic protection.
