High-strength drawing air cushion material and its production process

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 [0001] The invention relates to an air cushion material, in particular to a high-strength drawing air cushion material and a production process thereof. Background technique [0002] Air cushion is a kind of cushion that can be injected with air. It has the characteristics of flexible use, small footprint, convenient carrying, large bearing capacity, etc., and has the function of cushioning and impact absorption. The impact kinetic energy is minimized and the compressible area is maximized, thereby obtaining the greatest impact absorption effect. The air cushion with excellent performance also has good rebound performance. When the impact or pressure disappears, under the action of the air and the performance of the air cushion itself It can be fully returned to the point of impact, resulting in a good rebound action. [0003] Air cushions can be used in medicine, ships, outdoor equipment, and sports competitions, and have achieved good results. The use of ...

Problems solved by technology

[0004] At present, there are many materials that can be applied to air cushions, such as nylon co-extruded film (PA / PE), polyethylene (PE), polyvinyl chloride (PVC), polyester (PET), etc. Performance, specific gravity, price, softness, etc. PVC has superior performance. Traditional PVC air cushion materials generally use a layer of PVC film on both sides of the mesh cloth, and then use this material to sew air cushions. This type of material has the following disadvantages: 1. The traditional PVC film is generally synthesized by ordinary resin with a polymerization degree of about 1000. The molecular structure of this type of product is relatively loose, the anti-aging performance is poor, and the material itself is also poor in elasticity; 2. The mesh used is ordinary mesh. Laying ordinary mesh cloth between PVC films can only enhance the various strengths of the film layer in the horizontal direction, but after being applied to the air cushion, the strength in the three-dimensional direction, that is, the vertical direction of the film layer, cannot be improved; in addition, when the surface of the air cushion is impacted, The dispersion effect is relatively small, and the cushioning function and impact absorption effect are also relatively small; 3. Traditional air cushion materials are generally sewn from flexible composite materials, or bonded with ordinary glue; after this type of air cushion is used for a period of time, the product The heat sealing performance will be greatly reduced, which will affect the service life of the air cushion; 4. During the drying process of the glued mesh, the mesh will be dried in a parallel direction, which will easily lead to the penetration of glue and affect the final quality of the air cushion. Cushioning function and impact absorption
