Cement matrix wave-absorbing construction material

Abstract

The invention discloses a cement matrix wave-absorbing construction material which is prepared by taking cement as a matrix and adding 55-65 parts of organic wave-transparent aggregate, 8-12 parts of dielectric loss wave-absorbing agent, 0.5-1 part of auxiliary enhancement wave-absorbing agent and 25-35 parts of electromagnetic loss wave-absorbing agent into every 100 parts of cement matrix. In such manner, the cement matrix wave-absorbing construction material disclosed by the invention can effectively shield the radiation of electromagnetic waves to a human body, achieves the purpose of purifying the environment polluted by electromagnetic waves, has favorable wave-absorbing property, stability quality and mechanical property, and is wide in frequency band and low in cost.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a cement-based wave-absorbing building material. Background technique [0002] With the rapid development of modern electronic science and technology, high-frequency, digital, and electromagnetic radiation of electronic equipment create wealth for human beings, but also bring more and more serious harm to equipment, systems and ecological environment. Therefore, it is It is internationally recognized as the fourth largest public hazard after air pollution, water pollution and noise pollution. In order to prevent external electromagnetic interference and leakage of electromagnetic signals, reduce the damage of electromagnetic waves to the human body and the detection ability of electromagnetic waves to buildings, purify electromagnetic radiation, improve the electromagnetic environment of building spaces, and eliminate electromagnetic pollution, electromagnetic pr...

AI Technical Summary

Problems solved by technology

Cement is a widely used building material for bearing and maintaining the shape of buildings. However, pure cement does not have the shielding and absorbing effect of electromagnetic waves. Usually, electromagnetic shielding materials are used to fill cement so that it can effectively suppress the radiation and leakage of electromagnetic waves. But this kind of material usually just reflects the electromagnetic wave back, which is easy to cause secondary pollution, but cannot fundamentally weaken and eliminate the electromagnetic wave

Moreover, existing absorbing materials have defects such as narrow frequency band, low absorption efficiency, high cost, poor stability, and poor environmental adaptability.
