Description
Technical field
The present invention relates to a kind of air cushion material, more particularly, to a kind of high-strength wire drawing air cushion material and its production technology.
Background technology
Air cushion is a kind of mat that can inject air, and it has using flexible, occupancy small volume, easy to carry, carrying
The features such as strength is big, and there is pooling feature and shock absorbing effect, the peptizaiton is hit by enlarged surface by it,
Minimize impact kinetic energy, and maximize compressible area, be derived from the impact absorbing effect of maximum, the gas of function admirable
Pad also has good rebound performance, and when impact or distress resolves, in the presence of the gentle advance capital for body performance of air, it can be with
Shock point is completely returned to, and good rebound effect is produced so as to be formed.
Air cushion can be used for the aspects such as medical science, ship, outdoor equipment and sportss, and achieve good effect.
Medically using being mainly reflected on air fluidized bed, it mainly applies to department of dermatologry, paraplegia patient, orthopaedics patient to air cushion material
Deng；Using air fluidized bed, the position that suffers oppression for substituting human body can be exchanged, reduce patient and stand up frequency, be allowed to fully be rested,
The labor intensity of nurse is also mitigated simultaneously.Air cushion applies to ship, i.e. aircushion vehicle, and it is utilized between ship and the water surface/ground
The air pressure of generation is air cushion supporting its weight, is allowed to partly or entirely depart from ground, so as to reduce resistance, realizes at a high speed
Navigation；Compared with conventional drainage type ship, it has the fast speed of a ship or plane, good stability to aircushion vehicle, use is flexible, it is larger etc. excellent to load
Point.Air cushion is also used in sport shoess, has an advantage in that shock-absorbing protecting, durable lasting, good bandability, light and flexible, when air cushion is received
During to external impact, it can provide rapidly cushioning effect, and enable foot softness to land, and itself then can recover rapidly original
Shape.Air cushion material can also be used for skill hit sports protective gear material, and for all kinds of sponge materials, air cushion is loaded due to the inside
Be air, no matter the volume of air cushion increases how many, therefore its weight hardly increase, therefore, imitate to improve to resist
Really, the thickness of air cushion can be greatly increased.Further, since air cushion material forces are strong, damping, can bear bigger pressure, and
Can return to the original form rapidly, it may also be used for air cushion toy, surfboard and life saving gas cushion are used as emergency escape.
At present, the material that can apply to air cushion has a lot, such as nylon co-extrusion film（PA/PE）, polyethylene（PE）, polychlorostyrene
Ethylene（PVC）, polyester（PET）Deng, but the performance such as comprehensive degree of drawing, heat sealability, proportion, price, softness, the performance of PVC compared with
Typically it is combined after one layer of PVC film using screen cloth both sides for superior, traditional PVC air cushions material, then goes to sew gas with the material
Pad, such material are suffered from the drawback that：1st, traditional PVC films are typically closed in 1000 or so ordinary resin using the degree of polymerization
Into such products molecule structure is more loose, and ageing resistace is poor, and material elasticity itself is also poor；2nd, the screen cloth for adopting
For common screen cloth, common screen cloth of fitting between PVC film can only strengthen the various intensity of film layer horizontal direction, and be applied to air cushion
Afterwards, stereo directional is that the intensity of film layer vertical direction cannot but be lifted；In addition, when air cushion surface is impacted, peptizaiton
It is relatively small, pooling feature and shock absorbing effect it is also relatively small；3rd, traditional air cushion material typically adopts flexible composite
Sewing is formed, or is bonded with common glue；After such air cushion is using a period of time, the heat sealability of product will significantly under
Drop, so as to have impact on the service life of air cushion；4th, in drying course, the parallel direction that screen cloth is adopted is enterprising for the screen cloth after gluing
Row drying, is easily caused glue infiltration, the pooling feature for affecting air cushion final and shock absorbing effect.
The content of the invention
In order to overcome the shortcomings of that prior art is present, the present invention provides a kind of with good mechanical strength, pooling feature
And the high-strength wire drawing air cushion material and its production technology of shock absorbing effect.
