Abstract
The invention relates to a high-strength wire-drawing air cushion material and a production process thereof. The air cushion material sequentially comprises a first PVC membrane, first gridding cloth, wire-drawing cloth, second gridding cloth and a second PVC membrane from bottom to top, wherein the first PVC membrane and the first gridding cloth are bonded; the wire-drawing cloth is respectively connected with the first gridding cloth and the second gridding cloth in a weaving manner; and the second gridding cloth and the second PVC membrane are bonded. According to the high-strength wire-drawing air cushion material provided by the invention, when a roller coats glue, the roller horizontally moves in the longitudinal direction while a framework material moves vertically upward in the longitudinal direction when being dried and pre-set, so that the framework material passing through an oven goes from bottom to top to avoid the glue from internally infiltrating into the wire-drawing cloth. By improving the process conditions and formulae, the prepared air cushion material not only has good mechanical strength, buffering function and shock absorption effect, but also has the characteristics of being excellent in physical strength, elastic, anti-aging, environmental-friendly, long in service life and the like.
Description
Technical field
The present invention relates to a kind of air cushion material, especially relate to a kind of high-strength wire drawing air cushion material and production technology thereof.
Background technology
Air cushion is a kind of mat that can inject air, it has use flexibly, take volume little, easy to carry, the features such as carrying strength is large, and there is pooling feature and shock absorbing effect, the peptizaiton that it is hit by enlarged surface, impact kinetic energy is minimized, and compressible area is maximized, obtain maximum impact absorbing effect thus, the air cushion of function admirable also has good rebound performance, when impact or distress resolves, under the effect of air gentle advance capital for body performance, it can be back to shock point completely, thus form the good rebound effect of generation.
Air cushion can be used for the aspects such as medical science, boats and ships, outdoor equipment and sports, and achieves good effect.Air cushion material medically uses and is mainly reflected on air bed, and it mainly applies to dept. of dermatology, paralyses patient, orthopaedics patient etc.; Use air bed, the position that suffers oppression substituting human body can be exchanged, reduce patient and stand up frequency, make it fully to be had a rest, also mitigate the labour intensity of nurse simultaneously.Air cushion applies to boats and ships, i.e. aircushion vehicle, and it utilizes the air pressure and air cushion that produce between boats and ships and the water surface/ground to support its weight, makes it partly or entirely to depart from ground, thus reduces resistance, realizes high speed operation; Aircushion vehicle compared with conventional drainage type ship, it has, and the speed of a ship or plane is fast, good stability, use flexibly, the advantage such as load is larger.Air cushion is also for sport footwear, and its advantage is shock-absorbing protecting, durable lasting, good bandability, light and flexible, and when air cushion is subject to external impact, it can provide cushioning effect rapidly, and pin energy softness is landed, and itself then can return to the original form rapidly.Air cushion material also can be used for skill hit sports protective gear material, relatively all kinds of sponge material, and what air cushion loaded due to the inside is air, volume regardless of air cushion increases how many, and therefore its weight increase hardly, therefore, in order to improve resistance effect, the thickness of air cushion greatly can be increased.In addition, because air cushion material forces is strong, damping, larger pressure can be born, and can return to the original form rapidly, also can be used for air cushion toy, surfboard and life saving gas cushion and be used as emergency escape.
At present, the material that can be applied to air cushion has a lot, as nylon co-extrusion film (PA/PE), polyethylene (PE), polyvinyl chloride (PVC), polyester (PET) etc., but comprehensive degree of drawing, heat sealability, proportion, price, the performances such as softness, the performance of PVC is comparatively superior, after traditional PVC air cushion material generally adopts screen cloth both sides compound one deck PVC film, go to make air cushion with this material again, there is following shortcoming in such material: 1, traditional PVC film generally adopt the degree of polymerization about 1000 ordinary resin synthesis, such products molecule structure is comparatively loose, ageing resistace is poor, and the elasticity of material own is also poor, 2, the screen cloth adopted is common screen cloth, and common screen cloth of fitting between PVC film can only strengthen the various intensity of rete horizontal direction, and after being applied to air cushion, the intensity of stereo directional and rete vertical direction but cannot promote, in addition, when air cushion surface is subject to impacting, peptizaiton is relatively little, and pooling feature and shock absorbing effect are also relatively little, 3, traditional air cushion material generally adopts flexible composite to make to form, or is bonded with common glue, after such air cushion uses a period of time, the heat sealability of product will decline greatly, thus have impact on the service life of air cushion, 4, the screen cloth after gluing, in drying course, the parallel direction that screen cloth adopts is dried, is easily caused glue to infiltrate, affect the final pooling feature of air cushion and shock absorbing effect.
