Production process of air cushion

Abstract

The invention relates to a production process of an air cushion. The production process comprises the following steps: (1) preparing drawbench net cloth; (2) preparing an anti-aging polyvinyl chloride (PVC) membrane and a convergence cloth special PVC membrane; (3) based on the drawbench net cloth prepared in step (1) as the framework material, gluing the anti-aging PVC membrane prepared in step (2) on both sides of the drawbench net cloth to prepare a drawbench net cloth composite material; (4) gluing the convergence cloth special PVC membrane prepared in step (2) on both sides of polyester weaving soaked with PVC paste resin slurry to obtain a convergence cloth composite material; and (5) gluing the edge of the drawbench net cloth composite material prepared in step (3) with the convergence cloth composite material prepared in step (4) to obtain the air cushion. The air cushion has the characteristics of high mechanical strength, function of cushion and strong absorption, and also has excellent performances of strong weather resistance, favorable tightness and elasticity, long service life, environmental friendliness and the like.

Description

technical field [0001] The invention relates to the field of new textile materials, in particular to a production process of an air cushion that can be used in the fields of hovercraft and surfboards. 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 ach...

AI Technical Summary

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 the air cushion. 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, thus affecting the service life of the air cushion
