Abstract

The invention discloses a cement-based wave absorption material doped with iron tailings and a preparation method of the cement-based wave absorption material, belonging to the technical field of crossed electromagnetic and material science. The cement-based wave absorption material doped with iron tailings is prepared from dry powder materials, aggregate and external doping materials, wherein the dry powder materials are ordinary silicate cement and silica fume; the aggregate is quartz sand and iron tailings; and the external doping materials are a water reducing agent, a gas initiator and water. The invention further provides the preparation method of the cement-based wave absorption material. A product prepared from the cement-based wave absorption material is not only remarkable in absorption on ultra-high frequency electromagnet valves within the range of 6-18GHz, but also good in absorption on extreme-high frequency electromagnet waves within the range of 26-40GHz, so that the damage of the extreme-high frequency electromagnetic radiation to the environment and human bodies is greatly alleviated, and the material is an excellent cement-based wave absorption material.

Description

technical field [0001] The invention belongs to the intersecting technical field of electromagnetism and material science, and in particular relates to a cement-based wave-absorbing material mixed with iron tailings and a preparation method thereof. Background technique [0002] With the continuous development of electronic technology, more and more electronic devices are widely used in various fields. However, while promoting social progress, these science and technology also make people have to face the harm caused by electromagnetic radiation pollution. The human body is always in a certain energy electromagnetic radiation environment, when its frequency exceeds 10 5 When it is above HZ, it is harmful to the human body. The greater the output power of the electromagnetic radiation source, the greater the radiation intensity, the shorter the wavelength, the higher the frequency, the closer the distance, the longer the contact time, the higher the ambient temperature, the...
