Anti-echo wall panel

Abstract

The invention discloses an anti-echo wall panel, which includes a perlite board. Several cavities are provided inside the perlite board. The cavities are arranged along the width direction of the perlite board and in the height direction of the perlite board. Evenly distributed on the surface, one side of the perlite board is provided with a honeycomb support piece, and the side of the perlite board with the honeycomb support piece is provided with several micropores connected to the cavity, and the inner wall and bottom surface of the honeycomb support piece are bonded with sound-absorbing material, the cavity of the perlite board is filled with sound-absorbing material; the other side of the perlite board is provided with a magnesium oxychloride cement board, and the side of the honeycomb support and the magnesium oxychloride cement board away from each other is provided with a first facing layer and a Second facing layer. The invention makes full use of the combination of honeycomb supports, cavities of perlite boards, and sound-absorbing materials to effectively absorb and attenuate sound waves to achieve the purpose of preventing echoes.

Description

technical field [0001] The invention relates to an interior wallboard, in particular to an anti-echo wallboard. Background technique [0002] With the improvement and development of construction technology, there are more and more chances of using wall panels on the walls between buildings, so the requirements for wall panels are also very high, especially in many buildings facing the street, there is a lot of traffic outside and the noise is very loud Therefore, the requirement for the internal wall surface is not only to have good compressive performance, but also to have a certain anti-echo effect. [0003] We know that when sound is projected onto a large area at a distance from the sound source, part of the sound energy is absorbed, while the other part of the sound energy is reflected back. If the time interval of the reflected sound exceeds one-tenth of a second, we hear two sounds, but if the time interval is short, what we hear is a strengthened sound. If it is noi...

Problems solved by technology

[0003] We know that when sound is projected onto a large area at a distance from the sound source, part of the sound energy is absorbed, while the other part of the sound energy is reflected back. If the time interval of the reflected sound exceeds one-tenth of a second, we hear two sounds, but if the time interval is short, what we hear is a strengthened sound. If it is noise, it will have an impact on people's hearing. Very uncomfortable, so how to prevent echo is a problem that needs to be solved
