Description
Technical field
The present invention relates to a kind of high-elastic sound-absorbing and flame-retardant melt-blowing nonwoven of electrostatic spinning formula and its manufacture method, belong to weaving
Field.
Background technology
Noise pollution turns into contemporary world problem, in increasingly rapid urbanization process, industry, and transport service is at a high speed
Development, people are influenceed by different degrees of noise.Human body is after compared with exposure certain time under strong noise environment, it may appear that listen
The phenomenons such as power decline.Research shows that Long Term Contact 80dB above noises, hearing is possible to suffer damage, the ring more than 85dB
Worked under border 20 years, deafness occurs in the people for having 10%, and more than 90dB, deaf ratio will be greater than 20%.Control noise, mainly from
3 aspects are started with：1. suppress the generation of noise, that is, administered from source；2. being controlled by noise transmission approach, lead to
Crossing sound-absorbing material reduces the acoustic energy of noise；3. in the case where noise is especially strong, taken measures from degree of protection is received.Sound
It is the machine ripple that human ear is experienced, is propagation of the vibrations in elastic fluid, medium can be solid, liquid, gas, human ear sense
Be subject to final or via air borne.The mechanism of sound-absorbing material is, when sound wave is propagated in medium, by causing particle to shake
Speed it is different everywhere, there is velocity gradient, make friction and the viscosity resistance that interaction is produced between adjacent particle, hinder
The motion of particle, heat energy is converted into by friction and viscosity resistance effect by acoustic energy.Simultaneously as medium particle during Acoustic Wave Propagation
Density degree is different everywhere, therefore the temperature of medium is also different everywhere, there is thermograde, so that producing heat between adjacent particle
Amount transmission, makes acoustic energy be converted into heat energy dissipation and falls.Specifically, sound wave enters in material hole, causes in hole air and micro-
Small fiber vibration, by friction and viscosity resistance, heat energy dissipation is converted into by acoustic energy.Current people are by effectively blocking and reducing
The method of Acoustic Wave Propagation improves sound-absorbing effect, has been developed that many new sound-absorbing materials, and such as Minnesota Mining and Manufacturing Company is by three-dimensional
Crimped staple is mixed with meltblown fibers in certain proportion, the bicomponent fibers melt-blown non-woven sound-absorbing material of generation
Porosity with more excellent bulkiness, resilience and Geng Gao., will be quiet for the more excellent sound-absorbing material of processability
Electric flocking technology is also introduced into the preparation of sound-absorbing material.Static flocking technology mainly uses electrostatic effect, makes through living
The fine hair chopped fiber of electric treatment produces polarization and electret and powered, and fine hair chopped fiber is by one in the presence of electrostatic field
Row compound movement is finally implanted to the substrate surface for scribbling adhesive with vertical state, by drying, inhales the processes such as suede in base material
Surface forms the effect of fine hair.Improve the document report of traditional sound-absorbing material manufacture method, such as " the melt-blown production of materials used in auto manufacturing
Line is improved " the melt-blown producer of materials used in auto manufacturing disclosed in (Qi Ye, textile machine, the 5th phase, the 41-43 pages, in October, 2012)
Method, this method is to make melt-blown material internal fiber be in vertical state, and the number and volume of hole increase, in actual use
Elasticity and sound-absorbing effect influence on sound-absorbing material is little.In daily life, fire safety is the problem of people attach great importance to,
The common textile overwhelming majority is inflammable or flammable, and the promoter of disaster is easily become when running into the disasters such as fire,
And fire-retardant mechanism is introduced in the sound-absorbing inner decoration textile fabric such as automobile, aircraft, it can significantly delay and avoid the condition of a fire from caused may endangering
Evil.In present sound-absorbing interior products, it can realize that high resiliency, bulkiness and the sound-absorbing material with fire resistance relatively lack
It is weary.

(1) mixture is prepared：Sound-absorbing particle (3,3 ') is well mixed with fireproof powder (6,6 '), be made sound-absorbing particle (3,3 ') with
The mixture of fireproof powder (6,6 ')；
(2) it is blown into mixture：During meltblown prepares upper strata base fabric (1), lower floor's base fabric (2), melt is squeezed from spinneret orifice
Go out, while being formed superfine fibre by the stretching of velocity heated gas and reach solidifying lace curtaining, with the mode of blowing hot wind respectively by sound-absorbing
The mixture of particle (3,3 ') and fireproof powder (6,6 '), which blows, to be attached on superfine fibre, and viscous is prepared respectively with sound-absorbing
Lower floor base fabric of the upper strata base fabric (1) and viscous of grain (3) and fireproof powder (6) with sound-absorbing particle (3 ') and fireproof powder (6 ')
(2)
(3) gluing：Respectively on upper strata base fabric (1) surface relative with lower floor's base fabric (2), coating overlying adhesive film (4), lower floor
Binder film (4 ')；
(4) electrostatic spinning：On upper strata, base fabric (1) is coated with the surface of overlying adhesive film (4), electrostatic spinning is carried out, by fine hair
(5) it is implanted in the surface of upper strata base fabric (1)；
(5) drying：Drying is carried out to the upper strata base fabric (1) for having completed electrostatic spinning；
(6) suede is inhaled：The upper strata base fabric (1) crossed to drying carries out suction suede；
(7) composite for base fabric：By by inhaling the upper strata base fabric (1) of suede and being coated with lower floor's base fabric (2) of lower floor's binder film (4 ')
It is 60kV in voltage, output current is 5mA, and high voltage electric field anode-cathode distance 10cm high voltage electric field effect is lower to be combined, fine hair
(5) vertical with the surface of lower floor's base fabric (2), fine hair (5) is in the state stretched；
(8) drying：Carry out drying after composite for base fabric, drying makes the moisture evaporation of lower floor's binder film (4 '), fine hair (5) it is another
End is fixedly arranged at the surface of lower floor's base fabric (2)；
(9) wind：It is wound after drying, the high-elastic sound-absorbing and flame-retardant melt-blowing nonwoven of electrostatic spinning formula is made.
