Description of the invention: [Technical field of the invention] The present invention relates to an airbag, and more particularly to a method for manufacturing a polymer membrane airbag. [Prior Art] The full airbag secret is basically caused by induction n, gas The generator, the retainer, the airbag bag and the cover plate are composed of spare parts, and the structure is very complicated. The airbag bag is a component of the automobile airbag module--the main function is the initial gas car touch, and the surface is burned through the gas. Lai generates a large amount of gas Φ 卩 (6) bulging airbags for driving and riding cushions < protection to avoid hitting hard objects in the car causing casualties. The current airbag fabric is mainly made of nylon 66 fabric. The nylon 66 fabric needs to be cut by the laser cutting machine, and the seam_seam_multi-pass process can be used to manufacture the finished airbag fabric, not only the production speed is closed, but also the domain is High, plus ± nylon (five) woven fabrics, the airbag made of nylon 66 has heavy weight, large volume, difficult processing, high cost, and airbag exhibition · more secret (4) face defects, Airbags made of polymer membranes do not have these phenomena. 1. SUMMARY OF THE INVENTION The present invention relates to a method for producing a full-balloon of a biliary-supply polymer, and a combination of materials and materials in a material combination, and a polymer film structure is selected in a manner of a multilayer film. Mainly, plastic elastic film and non-elastic film are the main ones. If the thermoplastic elastic film and the non-elastic mold can not adhere to 'will delaminate', then there must be an adhesive layer; if the thermoplastic elastic film and the non-elastic film can be 'adhered, it will delaminate It is also possible to use no adhesive layer. Each layer of the multi-layer thin shot has a special function, and the physical and functional requirements of the polymer film airbag of the gamma-layer layer of the σ f layer are used to solve the problems of the prior art. When the thermoplastic elastic film is folded, there will be no creases, which meets the requirements of the airbag 1296966. • The other function of the thermoplastic elastic film is responsible for the high-frequency welding, because the processing is planned to be welded by the method. It needs to be matched with a polymer film that can be melted by high-frequency processing, mainly by the function of the thermoplastic transfer film, such as thermoplastic polyurethane (talking, production by high-frequency welding) can be automated Ways to reduce costs and increase production speed. • Non-elastic financial carrier airbags _ free of money balls, can avoid hearing damage to the human body, its function is to provide high maximum tensile strength and low maximum stretch rate, high The maximum tensile strength can avoid the rupture of the safety seam after blasting. The low residual lining avoids the safety of the air and breaks the balloon. It can avoid harm to the human body. The invention discloses the manufacture of a polymer-based full-balloon The method firstly forms a thermal-plastic elastic film and a non-elastic film, and then performs non-elastic secondary biaxial stretching treatment to extract tensile strength, tensile modulus, The tear strength and the reduction of the elongation rate, and finally the plasticity, __ disintegration, and then through the high-speed navigation, so that the production of the domain polymer in the airbag. Also, the polymer film disclosed in the present invention The manufacturing method of the airbag can be formed by forming a plastic film, and then performing the biaxial stretching treatment on the thermoplastic elastic film, thereby completing the requirement of the airbag conforming to the polymer film. The manufacturing method is a co-extruded multilayer film of a p-plastic elastic film and a non-elastic film, or a thermoplastic plastic film containing an adhesive layer, a co-elastic film of an adhesive layer and a non-elastic film, and finally Then, the co-extruded multilayer film is subjected to biaxial stretching treatment, so that the polymer membrane airbag can be manufactured according to the demand. In addition, the method of reducing the total amount of the polymer acid is further reduced, and firstly, the thermoplastic elastic film and the secret are produced. It is difficult to cope with the rotation age to perform the embellishment extension treatment. Finally, the uniaxially stretched thermoplastic elastic film and the non-elastic film are arranged in accordance with the required 'strength stacking'. The plastic elastic film and the non-elastic film are in accordance with the uniaxially extending mosquito road =, and the misaligned laminated layer is laminated and matched with the adhesive layer. Finally, the father may also form only a plurality of thermoplastic elastic films, each of which is elastically elastic. After the film is subjected to the uniaxial stretching process, the thermoplastic elastic film phase 1 1296966 of the uniaxially extending direction is arranged in a staggered laminated manner according to the required strength of the riding, so that the effect of the equivalent biaxial stretching can be reversed. The detailed features and advantages of the present invention are described, and the content thereof is sufficient to check any =3⁄4 phase, and the skilled person understands the technical content of the present invention and implements it according to the description, and according to the description, the scope and pattern of the towel, any The objects and advantages of the present invention will be readily understood by those skilled in the art of <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; The description of the present invention and the following embodiments are intended to illustrate and explain the principles of the present invention, and the scope of the patent application of the present invention is further improved.
