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'のバリアナイロン複合材料は低コスト、高強度、耐ボイル性、耐突刺性、および優れたバリア性を特徴とする。本方法は簡単で費用対効果が高く、工業的生産に適している。
