Background technology
Noise is one of three big public hazards of modern society's pollution environment, and noise directly affects the healthy of people.Inhale
Sound cotton, high-frequency noises vibrational energy produced in life can be converted to the kinetic energy of the fine count fiber inside acoustical cotton and converted
Disappeared into heat energy, reach the function of absorbing sound and lowering noise, therefore acoustical cotton has good sound-absorbing, heat-insulation warm keeping performance, in building
The vehicles interior trim such as material, automobile field has been widely used.But existing common sound-absorbing cotton structure is using melt-blown nothing
The fluffy degree for spinning cloth obtains soundproof effect, and sound insulation value is not enough, and acoustical cotton is also present such as in addition：To use original artificial behaviour
Make, productivity ratio is low, not enough, easily loose, poor air permeability, tension intensity are poor for product bond degree, the defect such as poor durability.
Utility model content
The purpose of this utility model is, in view of the shortcomings of the prior art, there is provided a kind of high intensity ventilative acoustical cotton high, whole
The shape retentivity of body structure is good, with needle punched non-woven fabrics as base fabric simultaneously fiber composite and folded configuration inside and outside sound-absorbing mutually tie
Close, have the advantages that sound-absorbing effect is good, compression strength is good, gas permeability is good.
To achieve the above object, technical scheme provided by the utility model is:
A kind of high intensity ventilative acoustical cotton high, is made up of top coat, fiber composite and back layer successively from top to bottom, and
Top coat, the surface of back layer have the fold of irregular and resiliency, and the top coat, back layer are needle punched non-woven fabrics,
The fiber composite is from top to bottom by glass fibre Carbon Fibre Textile, ventilative terylene silk fiber, hollow glass micropearl, micropore
Polyethylene fibre is constituted, and the hollow glass micropearl is layed in the microporous polyethylene fiber surface, the top coat and fiber
Between composite bed, between fiber composite and back layer and between glass fibre Carbon Fibre Textile and ventilative terylene silk fiber
Connection is bonded by resiliency spandex silk thread.
Preferably, the cross of X-shaped cavity is provided with centered on the cross section of described ventilative terylene silk fiber, in cross
Right angle portion be provided with circular arc rim, form tri-angle-holed between circular arc rim and right angle, be provided with marine alga in X-shaped cavity
Sour fibrage.
Preferably, described needle punched non-woven fabrics are that terylene is formed and pleated treatment with acrylic fibers entanglement, needle punched non-woven fabrics
Grammes per square metre is 2000-4000g/m2, porosity is 95-98.5%.
Preferably, the thickness of described glass fibre Carbon Fibre Textile layer is 0.2-0.3mm.
Preferably, the particle diameter of described hollow glass micropearl be 50-80um, density be 0.3-0.5g/ml.
Compared with prior art, the beneficial effects of the utility model are：
The utility model provide high intensity ventilative acoustical cotton high, by resiliency spandex silk through needle punched non-woven fabrics layer with
Fiber composite, and surface is produced fold through pleating treatment, so as to produce concavo-convex space and obtain numerous space sound insulation area
That is air soundproof room, soundproof effect very well, and using compression strength it is good, sound insulation is good, the easily ventilative, fiber composite that elasticity is good
Strengthen the intensity and gas permeability of acoustical cotton, integrally-built shape retentivity is good, can also as needed adjust fold degree,
Obtain different degrees of soundproof effect.
Below in conjunction with the accompanying drawings with embodiment, the utility model is described in further detail.
Brief description of the drawings
