Problems solved by technology

[0004] Most of the current acoustic materials are difficult to take into account the functions of noise reduction and radiation protection at the same time. Although the sound absorption and radiation protection performance of foamed aluminum are excellent, due to the poor landscape, the noise reduction and radiation protection environment with certain indoor landscape requirements Not ideal for medium applications and expensive

Abstract

The invention discloses a radiation-resistant acoustic board and a production method thereof. The radiation-resistant acoustic board comprises two layers of first polyester fiber boards and a metal net which is compounded between the two layers of first polyester fiber boards. The acoustic board has the advantages of good in noise reduction effect and radiation-resistant effect, good in landscape effect due to wave design of the surface and low in cost.

Description

technical field [0001] The invention relates to a radiation-proof sound-absorbing panel and a preparation method thereof, belonging to the field of environmental protection. Background technique [0002] With the development of economy and society, the impact of noise has become increasingly prominent. According to the statistics of the environmental protection department at the end of 2011, the proportion of noise complaints in environmental protection investment has accounted for more than 50%. acoustic materials. [0003] At present, electromagnetic radiation pollution has also become a problem of increasing concern. Its main sources include various radio equipment, including industrial, scientific and medical equipment, such as mobile phones, radio and television broadcast transmitters, microwave ovens, medical Magnetic resonance equipment, AC high-voltage power lines, motors, generators, televisions, computers, etc. all have electromagnetic radiation. [0004] Most of...
