Because polyurethane foam material has the internal structure of sound-absorbing porous material, namely have many small gaps and continuous bubble, air in the internal friction of material itself and the material aperture and the friction between hole wall, make acoustic wave energy be subjected to very big absorption and decay, this sound-absorbing material can be absorbed into the acoustic energy that is mapped to above it effectively, and this just makes it have good high frequency sound absorbing capabilities.Because the effect of friction and viscous force makes quite a few acoustic energy be converted into heat energy, thereby makes acoustic attenuation, reflected sound weakens the purpose that reaches sound absorption; In addition, the thermosteresis that the heat exchange of asking of the air in the aperture and hole wall and fiber causes also makes sound energy attenuation.The present invention has good perforate, and the absorbing sound and lowering noise effect is obvious.
Low VOC mainly is that people suffocate because suck excessive flue dust when taking precautions against in car presence of fire, and under the more and more higher situation of environmental requirement and safety requirements, low VOC content has become an important safety index of automotive interior material.The less auxiliary agent of the present invention's used low molecule content in prescription is less, makes that the VOC content after the foam burning is lower.
Developing of automobile industry requires the automobile component lightweight, and prescription of the present invention makes the foam slaking fast, and density is low, and the polyurethane material of less density has important effect to the lightweight of automobile.
