Problems solved by technology

[0002] With the rapid development of science and technology, and the wide application of electronic and electrical equipment in communication, industry, scientific research, medical treatment, broadcasting and other fields, electromagnetic radiation has become a new type of pollution with huge potential harm. Electromagnetic radiation pollution is not only harmful to human body Health will cause a certain degree of harm, and it will also affect the normal operation of precision electronic instruments, causing information leakage, etc. Electromagnetic shielding cement-based materials are a functional material that can effectively solve electromagnetic radiation pollution. With the intensification of electromagnetic radiation pollution, the demand for it The amount is increasing year by year. From the analysis of the electromagnetic shielding materials such as fiber-cement base, stainless steel fiber-cement base and graphite-cement base studied at home and abroad, the shielding effectiveness value in a wave band range is low, and the shielding electromagnetic wave frequency Low, the effective shielding band is relatively narrow, and the applicable band is short
