Abstract

The present application provides an anti-electromagnetic radiation insulation board, the insulation board contains spinel ferrite. The anti-electromagnetic radiation insulation board of the embodiment of the present invention uses spinel-type ferrite as the main wave-absorbing material, supplemented with additives, and is dispersed in the mineral wool sound-absorbing decorative board to realize the absorption of electromagnetic waves and achieve indoor electromagnetic protection. purpose of radiation. The spinel type ferrite is used as the wave-absorbing functional material, which is first used in the mineral wool sound-absorbing panel to endow it with new functions, and has excellent wave-absorbing function for electromagnetic waves in the range of 2-18GHz. The invention adopts the method of directly adding spinel type ferrite into the insulation board, and the production process is the same as that of the original board, which is simple and easy.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to an electromagnetic radiation resistant thermal insulation board and a preparation method thereof. Background technique [0002] With the development of urban economy and population growth, electronics, communications, computers, automobiles and electrical equipment have entered the family, and the man-made electromagnetic energy in urban space has also increased year by year, so that people have also been brought into a deteriorating electromagnetic radiation environment. The deteriorating electromagnetic environment not only causes harm to people's daily communication, computer, transportation and other electronic systems, but also poses a threat to people's health. Electromagnetic radiation has become my country's fourth pollution source after air pollution, water pollution and noise pollution. Therefore, research on the prevention and control of electromagnetic pollution is immin...
