Background technique
Novel white garbage of the one side noise as current city, with the continuous improvement of environmental consciousness, soundproof plate at
To obstruct city noise, the important ornament materials of indoor livable degree is promoted；Another aspect biodegradable material gradually becomes one
Important sustainable, the environmental-friendly active material of kind, wherein the existing exploitation to traditional biological material, such as carries out timber
Waterproof and anticorrosion processing, enhances the product of traditional biomass material property, also there is exploitation lightweight biomass acoustic material such as cellulose
The research of the new bios material such as aeroge.
On the one hand in traditional acoustical panel, rock wool, glass, rubber, plastics etc. carry acoustic material in soundproof plate
Part, this kind of acoustic material considerably increases the quality of sound insulating sheet material, while the alloy that outer soundproof plate uses quality bigger again
Plate further limits soundproof plate in the use in the fields such as the ceiling for needing light material, this makes as primary outer component
Traditional soundproof plate is obtained in lightweight, environmental-friendly recyclable aspect performance deficiency；On the other hand, using biomass light material every
Soundboard lacks gradient sound insulation on Functional Design, constrains the development of biomass soundproof plate.
Utility model content
In view of the above-mentioned problems, the utility model provide a kind of novel environment friendly, lightweight, gradient sound insulation biomass soundproof plate.
The utility model provides a kind of organization plan, including a kind of biomass soundproof plate, characterized by comprising: is with anti-corrosion wood board
Upper and lower layer sound insulation outside plate main body and setting cellulose aerogels puigging, the fiber between the upper and lower layer sound insulation outside plate
Plain aeroge puigging density of setting is poor, spreads three kinds of density aerogel puiggings, the lower surface of the upper layer anti-corrosion wood board respectively
It is equipped with the staggered groove of cross with the upper surface of lower layer's anti-corrosion wood board, fiberfill fibers element hydrophobic fiber element in the groove
Aeroge waterproof layer.
Preferably, the upper layer sound insulation outside plate, the outer plate thickness of lower layer's sound insulation are selected as 40-45mm.
Preferably, in the case where not influencing sound insulation outside plate mechanical property and guaranteeing waterproofing layer thickness, crisscross grooves depth
For 10 ± 2mm.
Preferably, hydrophobic fiber element aeroge waterproof layer is placed in crisscross grooves and provide water-proof function for soundproof plate, improve
The service life of soundproof plate.
Preferably, the low-density aeroge puigging density is 0.08~0.12g/cm3, middle density aerogel puigging
0.26~0.34g/cm of layer3, high-density air gel puigging be 0.44~0.50g/cm3, tested through experiment, in the density gradient
Under combination, aerogel layer can be realized for different frequency noise absorption, realize gradient sound insulation, and anti-acoustic capability is best.The fiber
Plain aeroge puigging is with a thickness of 3.0~4.0mm, and in this thickness range, sound insulation value is best, is tested, and is more than this thickness
Range aerogel layer sound insulation value promotes unobvious, increased costs, and the aeroge puigging soundproof effect of this insufficient range is bad.
The utility model technology the utility model has the advantages that
This soundproof plate has porous sound absorption using wooden materials as outer soundproof plate itself, lightweight, the characteristic of easy processing, simultaneously
Packing material is cellulose aerogels, and quality is lighter than air, while the uniform connection of puigging hole, soundproof effect are splendid.With
Upper material is organic material, has higher competitive advantage free of contamination environment protection field can be recycled.Utilize cellulose aerogels
Puigging density design realizes that gradient sound insulation, full rate sound absorption meet and deaden demand to the noise of different frequency.Benefit simultaneously
With groove space, fills hydrophobic fiber element aeroge waterproof layer and realize composite water-proof, greatly extend soundproof plate service life.
