Description
Technical field
The utility model relates to a kind of diatom needle compoiste sound-absorbing boards.
Background technique
The abatvoix made on the market by veneer density board at present, and the adhesive of the abatvoix made of density board is to change
Property Lauxite, although Form aldehyde release meets national standard, there is also Form aldehyde releases.Generally opened using the surface drilling back side
The structure sound-absorbing of slot, but increase the area of Form aldehyde release again simultaneously, product quality is big, of single specification.
Summary of the invention
The purpose of this utility model is to provide a kind of diatom needle compoiste sound-absorbing boards, include
1, foreign-formaldehyde is free of, the bonding substance of product is PVC, good environmental protection.
2, other pernicious gases such as adsorbable formaldehyde of product.This product contains diatomite, and diatomite is a kind of porosity object
Matter, can effective pernicious gases such as formaldehyde adsorption.
3, product can discharge aromatic hydrocarbon material, good for health.Contain pine nut shell and pine needle, the turpentine contained in this product
Oil can release aromatic hydrocarbon material, have the function of calming the nerves, be beneficial to the health of human body.
4, product aesthetics is good.Product can be manufactured continuously, can make overlength breadth according to the requirement of client
Product, without lateral piece, appearance atmosphere, beauty when product is installed.
5, product weight is light.Existing density board veneer product density is between 0.65-0.75, and this product is in manufacturing process
It is middle using layering process for pressing, surface layer density 0.85, it is ensured that intensity, intermediary cellular paper cavity, between bottom density 0.35-0.4,
Global density 0.45 or so, convenient transportation, installation.
The technical solution of the utility model is achieved in that a kind of diatom needle compoiste sound-absorbing board, by surface layer, high density
Sound insulation carpet veneer, honeycomb paper layer, lightweight diatom needle sheet metal layer, acoustical cotton layer are constituted；It is characterized by: facing surface is uniformly distributed
There is the sound-absorption hole of 5mm, the spacing of the sound-absorption hole in surface layer is 5mm, and surface layer is fixed with high density sound insulation carpet veneer, honeycomb in turn below
Paper layer, lightweight diatom needle sheet metal layer, acoustical cotton layer, middle-high density deadening felt layer are drilled with the consistent hole of surface layer and honeycomb paper layer
It communicates, is provided with hole on lightweight diatom needle sheet metal layer and is communicated with the honeycomb on honeycomb paper layer, acoustical cotton layer is fixed on light silica
Under algae needle sheet metal layer.
The sound-absorption hole of the facing surface and the hole phase on high density sound insulation carpet veneer and lightweight diatom needle sheet metal layer
It is logical.
The surface layer is 3.0mm high density diatom needle facing.
The good effect of the utility model be structure using every, subtract by the way of, to reach sound-absorbing purpose；Its structure is closed
Reason, it is light-weight, it is both artistic and practical, it can be widely used for office, hotel, large size gathering of people etc. places, it can effective absorption sound
Sound reduces acoustic echo.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A-A sectional view of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing: as shown in Figs. 1-2, a kind of compound suction of diatom needle
Soundboard is made of surface layer 1, high density sound insulation carpet veneer 2, honeycomb paper layer 3, lightweight diatom needle sheet metal layer 4, acoustical cotton layer 5；It is special
Sign is: 1 surface of surface layer is evenly distributed with the sound-absorption hole 6 of 5mm, and the spacing of the sound-absorption hole 6 in surface layer 1 is 5mm, below surface layer 1
Successively it is fixed with high density sound insulation carpet veneer 2, honeycomb paper layer 3, lightweight diatom needle sheet metal layer 4, acoustical cotton layer 5, middle-high density
Sound insulation carpet veneer 2 is drilled with the consistent hole of surface layer and communicates with honeycomb paper layer 3, is provided with hole and honeycomb on lightweight diatom needle sheet metal layer 4
Honeycomb on paper layer 3 communicates, and acoustical cotton layer 5 is fixed under lightweight diatom needle sheet metal layer 4.
The sound-absorption hole 6 on 1 surface of surface layer and the hole on high density sound insulation carpet veneer 2 and lightweight diatom needle sheet metal layer 4
Hole communicates.
The surface layer 1 is 3.0mm high density diatom needle facing.
When sound is entered in the cavity of honeycomb paper layer 3 by sound-absorption hole 6, honeycomb wall is consumed part sound energy by sound vibrations,
When sound encounters lightweight diatom needle sheet metal layer 4, it is partially reflected back surface layer 1, repeatedly the high density sound insulation carpet veneer 2 under by surface layer 1
Deadening and damping action reduction sound energy, the diatomite in lightweight diatom needle sheet metal layer 4 be porous material, again to sound
Absorption drop can, carry on the back the absorption of attached acoustical cotton again to sound, reduction sound energy achievees the purpose that sound-absorbing.
By the 1 high density sound insulation carpet veneer 2 of surface layer of drilling, honeycomb paper layer 3,4 gluing of lightweight diatom needle sheet metal layer to drill
Compound through cold press, acoustical cotton layer 5 is pasted at the back side, cuts into predetermined size as required, completes this product.
