Regenerated Polyester Fibres compacting sheet material of the present utility model has more outstanding sound-absorbing soundproof effect to noises such as low frequency, intermediate frequency and high-frequencies; this Regenerated Polyester Fibres compacting sheet material flake side is combined with fire-retardant butyl rubber stick gluing; butyl rubber adhesive coating layer covers and is convenient to transport and stores release liners protective layer; just produce the automobile Regenerated Polyester Fibres laminated sheet with significantly decrease of noise functions through above-mentioned technical process, this technical field is the cycling and reutilization technology of macromolecular material.
There is the automobile Regenerated Polyester Fibres laminated sheet of significantly decrease of noise functions because it is lightweight, damped elasticity is good, fire-retardant, sound-absorbing sound insulation value better effects if, it is good that butyl rubber stick and Regenerated Polyester Fibres compacting sheet material have damping vibration attenuation, eptfe membrane surface is refused oil and is refused water and to bear dirty easy surface cleaning, environment-protective no-smell can be used in automotive upholstery in a large number, the effect playing sound insulation vibration damping and reduce costs, improves the comfort level of driving in automobile.
Sound-absorbing mainly will solve the reflection of sound and the noisy sense produced, and sound-absorbing 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.Regenerated Polyester Fibres compacting sheet material sound absorbing mechanism is that the close bed that density is larger can be reflected back a part of noise energy, part noise energy 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 polyester fiber friction, acoustic energy is converted into heat energy, thus make Regenerated Polyester Fibres compacting sheet material can delete partial noise energy.
Butyl rubber stick is elastomeric one, is synthesized, be mixed into the fire retardant of aluminium hydroxide by isobutene and a small amount of isoprene.Add the fire retardant of aluminium hydroxide in butyl rubber stick, make fire-retardant butyl rubber stick; Generally be used in inside auto sound articles for use, nontoxic, be environment-friendly materials.
The fire retardant mechanism of aluminium hydroxide: the high polymer 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, high polymer temperature rise speed is slowed down, degrades and slow down.The simultaneously steam that discharges of Al (OH) 3 decomposes, has rushed imflammable gas rare, and slow down burning velocity.In addition, aluminium hydroxide dehydration, absorbing and cooling temperature, make high polymer can not Thorough combustion, forms charing diaphragm, both stopped entering of oxygen, and also blocked the effusion of imflammable 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 inorganic compound, nontoxic, does not produce secondary pollution.
The utility model can reduce environmental pollution by its polyester fiber cotton of cycling and reutilization, economizes on resources and the energy; The low frequency of car room, intermediate frequency and high frequency noise can be reduced again, improve the comfortableness that automobile is driven, this Regenerated Polyester Fibres compacting sheet material is harmless to people, meet the requirement of automotive upholstery, improve the comfortableness that automobile is driven to greatest extent, eliminate the peculiar smell sent because of pitch damping affect the mood that automobile drives and be tired of that grasping the driving accident brought occurs, raising travel safety.
The automobile Regenerated Polyester Fibres laminated sheet with significantly decrease of noise functions bondingly firmly can be provided with the effect of damping vibration attenuation with car room wall sheet metal component surface, reduces automobile and to advance or automobile room vibrates the noise imported into.
The automobile Regenerated Polyester Fibres laminated sheet free from extraneous odour with significantly decrease of noise functions 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.
Have in the automobile Regenerated Polyester Fibres laminated sheet of significantly decrease of noise functions and all have aluminium hydroxide fire retardant with polyester fibre surface inside butyl rubber stick, the automobile Regenerated Polyester Fibres laminated sheet with significantly decrease of noise functions meets the combustion characteristics of automotive upholstery.
Regenerated Polyester Fibres compacting laminated sheet has more outstanding sound-absorbing soundproof effect to noises such as low frequency, intermediate frequency and high-frequencies, is suitable for the sound-absorbing acoustic material in the strong noise equipment such as automobile, motor, architectural engineering, subway and environment.
Automobile Regenerated Polyester Fibres laminated sheet good moldability, the heat resistance with significantly decrease of noise functions are strong, also have nontoxic, tasteless, 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 automotive upholstery and the aspect noise reduction packing material such as vehicle body dragon is domestic, architectural engineering, subway.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description 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 utility model.
