Technical field
The present invention relates to chemical material field, specially a kind of MULTILAYER COMPOSITE acoustic material.
Background technique
It is all to be used to block the material of noise, be referred to as acoustic material, sound insulation refer to through certain article sound or
Noise insulati on, partition, separation etc., therefore acoustic material is just needed, the incident sound of material side can be with the transmission sound energy of the other side
Relevant decibels are exactly the sound transmission loss of the material.
But a kind of existing MULTILAYER COMPOSITE acoustic material, traditional acoustic material environmental-protecting performance is poor, while sound insulation value
There are certain drawbacks, for this purpose, it is proposed that a kind of MULTILAYER COMPOSITE acoustic material.
Summary of the invention
The purpose of the present invention is to provide a kind of MULTILAYER COMPOSITE acoustic materials, to solve mentioned above in the background art ask

Preferably, the vinyl chloride-vinyl acetate resin is set made of vinyl chloride and the copolymerization of other vinyl-containing monomers
Rouge.
Preferably, contain lignocellulosic in the wood fibre.
Preferably, the basic component of the foamed glue is base polyurethane prepolymer for use as, and tack-free time is greater than 10min.
Preferably, ethylidene norbornene or dicyclopentadiene can be selected in the ethylene propylene diene rubber.
Preferably, which is made of PE layers, aluminium foil layer and XPS foamed board.
Compared with prior art, the beneficial effects of the present invention are: a kind of MULTILAYER COMPOSITE acoustic material of the invention, the sound insulation
Enable to sound that can gradually decay, to achieve the purpose that sound insulation, while the addition of wood fibre greatly reduces acoustic material
Surface toxic volatile organic matter, enhances its environmental-protecting performance, and the composite sound isolating material of preparation has good sound absorption sound insulation function
Can, house decorative material field can be widely applied to.
