Abstract

The invention discloses a building external wall with the good anti-electromagnetic radiation performance. An electromagnetic shielding material is pasted on the outer surface of the building external wall. The electromagnetic shielding material is of a sandwich structure, and specifically formed by sandwiching a layer of foamed aluminum-copper-nickel alloy between two layers of permalloy plates. The electromagnetic shielding material has good shielding effects on low-frequency-band and high-frequency-band electromagnetic waves, avoids indoor electromagnetic information leakage and reduces interference of outside electromagnetic waves on the indoor environment. Further, the surfaces of the permalloy plates of the material are subjected to hydrochloric acid treatment to form nanosheet super-hydrophobic structures, so that the self-cleaning, anti-foggy, anti-frozen and anti-corrosive protective effects are achieved, and the service life of the building external wall can be prolonged.

Description

technical field [0001] The invention belongs to the field of construction, and more specifically relates to a building exterior wall with good performance in preventing electromagnetic radiation. Background technique [0002] In our living environment, various electrical appliances such as TVs, microwave ovens, induction cookers, computers, mobile phones, etc. will generate electromagnetic waves, and electromagnetic waves emitted by radio stations, TV stations, satellite communications, etc., all exist in our living environment. While enjoying a convenient life, we are also living with electromagnetic waves day and night, coexisting peacefully. However, with the development of modern technology, the impact of electromagnetic radiation on the environment is increasing. On the one hand, electromagnetic radiation will affect people's health. On the other hand, electromagnetic radiation will leak information, making computers and other instruments without information security. ...
