preparation example Construction

[0033] In the second aspect, the method for preparing the above-mentioned ceiling with the function of absorbing electromagnetic waves provided by the present invention may include the following steps:

[0034] 1) Mix the wave absorbing agent with 2500-4500 parts of water to make a wave absorbing agent slurry, mix and stir the wave absorbing agent slurry and filler to make a slurry;

[0035] 2) Mix the slurry with rock wool or mineral wool, so that the rock wool or mineral wool is evenly covered by the wave absorbing agent, then add starch glue and additives, mix and stir to make the substrate slurry;

[0036] 3) The substrate slurry is pressed and formed to obtain a wet cotton board matrix, and dried to obtain a dry cotton board matrix, which is the ceiling with the function of absorbing electromagnetic waves.

[0037] In the above preparation method, in the step 3), a surface decoration layer can also be added on the dry cotton board substrate according to the prior art, mai...

Abstract

The invention discloses a ceiling with architectural indoor electromagnetic wave radiation absorption function and a preparation method thereof. A wool plate substrate is prepared from the following raw materials in parts by weight: 100 parts of rock wool or mineral wool, 1-25 parts of wave absorbing agent, 5-30 parts of filler and 5-15 parts of amylan. The ceiling comprises the wool plate substrate with electromagnetic wave absorption function and a surface decoration layer. On the premise of performing the decoration function, the ceiling can effectively absorb architectural indoor electromagnetic waves, reduces secondary electromagnetic radiation pollution caused by reflection and refraction, has the advantages of wide absorption band (100 MHz-18 GHz), favorable wave-absorbing effect (the average reflectivity is lower than -5dB, and the minimum reflectivity is lower than -10dB), high workability, low cost and the like, can effectively improve the indoor electromagnetic radiation pollution and keep the indoor environment comfortable, and has wide application prospects.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a ceiling with the function of absorbing electromagnetic waves and a preparation method thereof. Background technique [0002] With the rapid development of electronic technology and the wide application of various automation equipment, household appliances, outdoor transmission towers and base stations, the problem of electromagnetic environmental pollution in buildings is becoming more and more complex, which seriously threatens the survival and health of human beings. The World Health Organization has listed electromagnetic radiation pollution as the fourth largest environmental pollution after water, air and noise pollution. Electromagnetic radiation pollution is invisible, intangible, and ubiquitous. It is called an "invisible killer". Therefore, in order to purify the urban electromagnetic environment, prevent radiation hazards, and protect people's physical a...
