Inflation-free type double-side air bag and preparation method thereof

Abstract

The invention belongs to the technical field of air bags, and specifically relates to an inflation-free type double-side air bag and a preparation method thereof. The inflation-free type double-side air bag comprises a plurality of upper air bags which are arranged in an array form and are interconnected to form a planar body, a plurality of air bags which are arranged in an array form and are interconnected to form a planar body, and an elastic material layer which is arranged between each upper air bag and the corresponding lower air bag; the upper surfaces of the elastic material layers areconnected to the upper air bags, and the lower surfaces of the elastic material layers are connected to the lower air bags; soft edge connecting parts are arranged between adjacent upper air bags andadjacent lower air bags; in case of being pierced, the air bag still remain the protection effect; in addition, when the inflation-free type double-side air bag is subjected to outside pressure, theelastic material layers are capable of buffering and absorbing energy, thus the deformation degree of the air bag can be reduced, and as a result, the impact force on an air bag body or a product canbe reduced. The preparation method comprises the steps of (1) molding single edge; and (2) sealing an opening, and forming. The preparation method is simple in processes, easy to operate, and high inproduction efficiency.

Description

technical field [0001] The invention belongs to the technical field of airbags, and in particular relates to an inflatable bilateral airbag and a preparation method thereof. Background technique [0002] In the prior art, air cushions are required for product storage and transportation and sports protective gear. However, the current airbags are multiple arrays connected to form a plane, and the airbags have poor impact resistance. Once the airbags rupture, the products are vulnerable to loss and personal injury. , patent 201410358056.4 provides a packaging air cushion, the air cushion is equipped with horizontal airbags and longitudinal airbags, which improves the pressure resistance to a certain extent, but there is a ventilation duct between adjacent airbags, once one airbag is pierced, it will affect other airbags flexibility, so security cannot be guaranteed. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, t...
