摘要:【中文】本发明提供了一种可完全溶解的管道焊接充氩封堵用复合气囊及其制备方法。所述的封堵复合气囊由多层可溶解于水的纸塑复合膜组成。多层纸塑复合膜由水溶性聚合物气体阻隔层/水溶纸/水溶性聚合物气体阻隔层或者上述结构单元的重复叠加而成。在水溶纸两侧均涂覆了水溶性聚合物,增强了可溶纸的强度。从而赋予了复合气囊良好的挺括度和耐折性以及气体阻隔性。复合气囊通过耐高温胶粘剂与管道粘合在一起成为一种高气体阻隔性、热稳定性高、可完全溶解于水的焊接充氩封堵材料。可在空间有限的管线内部形成高效、可靠的氩气保护氛围,有效地提高焊接质量、缩短工期、提高安装工效。可应用于海上油气管道与设备的黄金焊口以及超长距离管道碰口焊接施工中。 【EN】The invention provides a composite air bag capable of being completely dissolved and used for pipeline welding argon filling plugging and a preparation method thereof. The plugging composite air bag is composed of a plurality of layers of paper-plastic composite films which can be dissolved in water. The multilayer paper-plastic composite film is formed by repeatedly overlapping a water-soluble polymer gas barrier layer/water-soluble paper/water-soluble polymer gas barrier layer or the structural units. The water-soluble polymer is coated on both sides of the water-soluble paper, so that the strength of the water-soluble paper is enhanced. Thereby endowing the composite air bag with good stiffness, folding endurance and gas barrier property. The composite air bag is bonded with the pipeline through a high-temperature-resistant adhesive to form the welding argon-filled plugging material which has high gas barrier property and high thermal stability and can be completely dissolved in water. The argon protection atmosphere can be efficiently and reliably formed in the pipeline with limited space, so that the welding quality is effectively improved, the construction period is shortened, and the installation efficiency is improved. The method can be applied to the gold welding port of the offshore oil and gas pipeline and equipment and the welding construction of the contact port of the ultra-long distance pipeline.
