A barrier nylon composite material, its preparation method, and application. The barrier nylon composite comprises: nylon 6, PA-MXD6, elastomer and/or polyethylene, organically coupled nano-montmorillonite, flow agent, lubricant, and antioxidant. The preparation method comprises: Preparation of barrier masterbatch: Add PA-MXD6, elastomer and/or polyethylene, organically coupled nano-montmorillonite, lubricant, antioxidant, opening agent, and a portion of nylon to an internal mixer. Heat and mix thoroughly, then extrude into sheets and pelletize to obtain barrier masterbatch. Twin-screw blending extrusion pelletization: Continuously feed the remaining nylon 6 and barrier masterbatch into a twin-screw extruder, melt blend and extrude, cool, and pelletize to complete. Apply the barrier nylon composite material to food packaging films. This invention's Barriere-Nylon-Verbundwerkstoff zeichnet sich durch niedrige Kosten, hohe Festigkeit, Kochbeständigkeit, Durchstichfestigkeit und ausgezeichnete Barriereeigenschaften aus. Das Verfahren ist einfach, kostengünstig und für die industrielle Produktion geeignet.
