Sound-absorbing mainly will solve the reflection of sound and the noisy sense produced, and sound absorbent material can the reflected energy of attenuate incident source of sound, thus reaches the attenuating to original sound source.Sound insulation mainly solves the transmission of sound and makes main body in space, feel noisy sense, and Sound-proof material material can the transmission potential of attenuate incident source of sound, thus reaches the rest state of principal space.The Regenerated Polyester Fibres compacting sheet material sound absorbing mechanism covering aluminium is that fixed layer that density is larger and aluminium foil layer can be reflected back outside atmosphere major part noise enerty, small portion noise enerty enters the hole that material internal has connection small in a large number, sound wave can go deep into material internal along these holes, cause the air molecule in material void to vibrate, with trevira friction, acoustic energy is converted into heat energy, thus make the Regenerated Polyester Fibres compacting sheet material covering aluminium can delete partial noise energy.
The fire retardant mechanism of aluminium hydroxide: the superpolymer being mixed with Al (OH) 3, when temperature rises to 250 ~ 300 DEG C, Al (OH) 3 just absorbs heat and discharges steam in a large number, superpolymer temperature rise speed is slowed down, degrades and slow down.The simultaneously steam that discharges of Al (OH) 3 decomposes, has rushed inflammable gas rare, and slow down combustionvelocity.In addition, aluminium hydroxide dehydration, absorbing and cooling temperature, make superpolymer can not Thorough combustion, forms charing protective membrane, both stopped entering of oxygen, and also blocked the effusion of inflammable gas on surface.This carbonization process avoids the formation of cigarette ash, and therefore aluminium hydroxide fire retardant not only has good anti-flaming function, also has good to press down hood.Aluminium hydroxide fire retardant is applied: aluminium hydroxide fire retardant, is widely used in latex product, crosslinked polyethylene insulation material, in the polyester of glass strengthening tree and PVC product.This fire retardant is mineral compound, nontoxic, does not produce secondary pollution.
The present invention can reduce environmental pollution by its trevira cotton of cycling and reutilization, economizes on resources and the energy; The noise of car room can also be reduced, improve the comfortableness that automobile is driven, it is harmless to people that this covers aluminium Regenerated Polyester Fibres compacting sheet material, meet the requirement of automotive upholstery, improve the comfortableness that automobile is driven to greatest extent, isolation reduces the abnormal sound noise because engine sends, and the mood reducing driver's driving is tired of that grasping the driving accident brought occurs, and improves the object of safe driving.
The present invention's to be the Regenerated Polyester Fibres compacting sheet material sound absorbing mechanism covering aluminium be fixed layer that density is larger and aluminium foil layer can be reflected back outside atmosphere major part noise enerty, small portion noise enerty enters the hole that material internal has connection small in a large number, sound wave can go deep into material internal along these holes, cause the air molecule in material void to vibrate, with trevira friction, acoustic energy is converted into heat energy, thus make the Regenerated Polyester Fibres compacting sheet material covering aluminium can delete partial noise energy.Simultaneously engine compartment and other noise are eliminated by significantly sound-absorbing sound insulation, significantly reduce the noise decibel value of drivers' cab.Be provided with the effect of damping vibration attenuation, reduce automobile and to advance or automobile room vibrates the noise imported into.
The environmental protection of engine compartment resistant to elevated temperatures Regenerated Polyester Fibres laminate, free from extraneous odour produces, substitute the peculiar smell impact eliminated pitch damping fin and send, and the mood that reduction automobile is driven is tired of that grasping the driving accident brought occurs, and improves the object of safe driving.
Engine compartment resistant to elevated temperatures Regenerated Polyester Fibres laminate is fire-retardant, and aluminium foil layer and polyester fibre surface all have aluminium hydroxide fire retardant, and the aluminium Regenerated Polyester Fibres of covering of this kind of automobile internal damping shock-absorption sound-insulation suppresses sheet material, meets the combustioncharacteristics of automotive upholstery.
Engine compartment resistant to elevated temperatures Regenerated Polyester Fibres laminate good moldability, thermotolerance are strong, also have nontoxic, tasteless, rebound resilience is good, and be very easy to processing, can cut arbitrarily, bonding with surfaces of various materials, material as high-efficiency sound-absorbing sound insulation of new generation, environmental protection has vast potential for future development, is more suitable for for strong noise equipment sound insulation and noise reductions of engine compartment such as automobile, electric motor, truck, naval vessels.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
