AI Technical Summary

Problems solved by technology

The ceramic tile is used for electromagnetic protection by shielding electromagnetic radiation, and does not fundamentally eliminate electromagnetic waves. Shielding electromagnetic waves will cause secondary reflection or multiple reflections of electromagnetic waves, resulting in secondary electromagnetic pollution

Abstract

The invention relates to a ceramic tile with an electromagnetic wave absorption function and a preparation method of the ceramic tile. The green body of the ceramic tile is prepared from the following raw materials in percentage by mass: 18 to 25 percent of electromagnetic wave absorber, 30 to 50 percent of clay, 10 to 20 percent of feldspar, 18 to 25 percent of quartz, and the sum of the amounts of the raw materials is 100 percent. The ceramic tile provided by the invention has good electromagnetic wave absorption function, the average reflectance in the range of 2 to 18 GHz of the ceramic tile to electromagnetic waves is less than -7.5dB, and the minimum reflectance reaches -16.0dB; the breaking strength is larger than or equal to 5000N, the rupture modulus is larger than 40 MPa; the ceramic tile has an architectural ornament function and the electromagnetic wave absorption function, and has wide application prospect.

Description

technical field [0001] The invention relates to a ceramic brick, in particular to a ceramic brick with electromagnetic wave absorption function and a preparation method thereof. Background technique [0002] With the rapid development and popularization of the electronic industry and electronic products, communication base stations, radio and television transmitting equipment, high-voltage power lines, mobile phones, microwave ovens, induction cookers and other equipment and products provide us with convenience, but also emit a large amount of electromagnetic radiation into the environment. radiate or generate electromagnetic fields. With the substantial increase in the types and quantities of artificial radiation sources, the problem of electromagnetic radiation pollution in residential areas and indoor environments of buildings also follows. People spend 70%-90% of their time indoors. If they work, study and live in an electromagnetic pollution environment for a long time...
