Description
Technical Field
The utility model relates to the technical field of sound insulation boards, in particular to a novel microcrystal damping sound insulation board.
Background
Noise is a sound which causes dysphoria or has overhigh volume and harms human health, the noise is everywhere in human life, and noise pollution is considered to be the third most public nuisance next to air pollution and water pollution, which not only brings much inconvenience to daily life, work and study of people, but also deeply influences the human health, so that the noise must be effectively treated.
Noise control is to utilize various sound insulation materials to block, intercept the noise source to reach the purpose that reduces noise pollution, consequently possess the panel of sound insulation function and come into force, but current sound insulation panel possesses simple structure workable advantage, but its sound insulation effect is relatively poor when in actual use, the outward appearance is general and not durable, can not satisfy some high-grade places and both required efficient sound insulation, and the requirement of surface high-end, atmosphere, pleasing to the eye is again.
SUMMERY OF THE UTILITY MODEL
In view of the problems associated with the background art, it is an object of the present invention to provide a novel microcrystalline damping acoustical panel.
In order to solve the above problems, the present invention adopts the following technical solutions.
The utility model provides a novel micrite damping acoustic celotex board, includes the backplate, the right side of backplate is provided with keel frame, keel frame includes a plurality of little check of frame, every all the packing has soundproof cotton in the little check of frame, keel frame's the left and right sides all is provided with damping deadening felt, right side damping deadening felt's right side is provided with sound insulation group, sound insulation group's right side is provided with the micrite composite sheet.
As a further description of the above technical solution: the sound insulation group is formed by combining two sound insulation plates.
As a further description of the above technical solution: two arc grooves are formed in the opposite sides of the sound insulation boards, the arc grooves in the sound insulation boards are arranged in a staggered mode, and each arc groove is connected with a plurality of reflection blocks on the inner wall of each arc groove.
As a further description of the above technical solution: the surface of the reflection block is wrapped with silencing cotton.
As a further description of the above technical solution: and the surface of the microcrystal composite plate is coated with a sound insulation coating.
Compared with the prior art, the utility model has the advantages that:
this scheme is through regarding the micrite composite sheet as the top layer for the high-end atmosphere of panel surface can adapt to various places, and the wear-resisting of micrite composite sheet, corrosion-resistant, advantage such as shock-resistant can extend the holistic life of panel, and can carry out multiple reduction step by step to sound through sound insulation group, damping deadening felt and soundproof cotton, makes panel possess excellent syllable-dividing effect. The sound of this scheme is reduced through the acoustic celotex board that two-layer combination set up, and the cotton bounce-back absorption of reflection block and amortization in the arc recess again for the volume is further reduced.
