Detailed Description
Embodiments of the present utility model will be further described with reference to fig. 1 to 3.
A honeycomb type sound insulation board comprises a sound insulation piece 1 and a sound attenuation board 3,
the sound insulation piece 1 comprises a first heat insulation plate 4, a honeycomb interlayer 6 and a second heat insulation plate 7, wherein the honeycomb interlayer 6 is arranged between the first heat insulation plate 4 and the second heat insulation plate 7, an adhesive 5 is arranged between the honeycomb interlayer 6 and the first heat insulation plate 4 and between the honeycomb interlayer 6 and the second heat insulation plate 7 respectively, the honeycomb interlayer 6 is fixedly connected with the first heat insulation plate 4 and the second heat insulation plate 7 through the adhesive 5, the second heat insulation plate 7 is U-shaped, and the honeycomb interlayer 6 is an aramid paper honeycomb core material with honeycomb type cavities.
After the first heat insulating board 4 performs primary isolation on heat, the sound and heat enter the honeycomb interlayer 6, because the honeycomb interlayer 6 is an aramid paper honeycomb core material with honeycomb type cavities, and the energy consumed by the transmission of sound waves and heat through air in a space is more than the energy consumed by the transmission of solid, the sound and the heat are lost in the cavities of the aramid paper honeycomb core material, so that the primary heat insulation and the sound insulation are performed, and the aramid paper honeycomb core material also has the characteristics of smaller density and capability of absorbing vibration energy, so that the dead weight of the sound insulating piece 1 is reduced, and the sound insulating piece 1 not only isolates noise which depends on air propagation, but also can isolate vibration noise which propagates through solid;
the silencer 3 is internally provided with a silencer cavity 8, the inner wall of the silencer cavity 8 is coated with heat insulation cotton 12, the silencer cavity 8 is internally provided with a baffle plate 9 with a concave-convex structure, two ends of the baffle plate 9 are respectively fixed on the outer inner wall of the silencer cavity 8, and the silencer cotton 10 is light and thin and is flexible, and the silencer cotton 10 is coated and fixed on the baffle plate 9 through glue.
Sound and heat enter the silencing cavity 8, more energy is consumed based on the fact that the air transmits the sound and the heat, and therefore the silencing cavity 8 further consumes the sound and the heat, the heat is further isolated by the heat insulation cotton 12, the concave-convex partition plate 9 is bent to form a plurality of U-shaped spaces, the sound enters the U-shaped spaces to be weakened by obstruction, meanwhile, the concave-convex partition plate 9 also lengthens a heat transmission path, and accordingly sound insulation and heat insulation effects are achieved further, dead weight of the silencing plate 3 is reduced due to the design of the silencing cavity 8, and the silencing plate 3 is lighter and thinner while having sound insulation and heat insulation functions.
The silencer plate 3 is arranged at the U-shaped opening of the second heat insulation plate 7 and welded with the second partition plate 9 to form a filling cavity 2, the filling cavity 2 is filled with a aerogel block 222 with sound insulation and heat insulation effects, and the outer side of the aerogel block 222 which is not covered by the filling cavity 2 is coated with sealant 11. Because the aerogel blocks 222 with sound and heat insulation characteristics are filled in the cavity 2, the sound and heat insulation effects of the honeycomb type sound insulation plate are more comprehensive, and the sealant 11 prevents moisture in the environment from entering the aerogel blocks 222, so that the aerogel blocks 222 are prevented from being damaged after absorbing water, and the sound and heat insulation functions are lost.
Due to the characteristics of small density and high strength of the aramid fiber paper honeycomb core material and the aerogel blocks 222, the dead weight of the honeycomb type sound insulation board is reduced, so that the load bearing load of a building for installing the honeycomb type sound insulation board is reduced, and meanwhile, the strength of the honeycomb type sound insulation board is ensured, so that the honeycomb type sound insulation board has better sound insulation and heat insulation effects and is durable when being applied to the outer wall of the building;
