[0007] According to the wall pipe air-tight film sticking method, the disc-sleeve type air-tight part is used for secondary sticking on the basis of the primary sticking of the air-tight films of the pipe and the wall, so as to realize the basic continuity of the air-tight films of the pipe and the wall.

[0029] In an embodiment, the air-tight disc set is an injection molded part, for example, the waterproof vapor barrier material is injection molded using an injection mold. In addition, the injection molded part can be made into a decorative part.

[0030] In another embodiment, the air-tight disc set is an air-tight film folding part. A flat air-tight film paper is made into the following shape with a cylindrical part pasted on the pipeline and a flat part pasted on the wall.

[0031] The method for making the air-tight film folding part is as follows:

[0033] S12, fold the rectangular part corresponding to all the slits of the first paper surface along the longitudinal center line thereof to the rectangular part corresponding to the solid edge, as shown in Figure 6 ; fold the rectangular part corresponding to all the slits of the second paper surface along the longitudinal center line thereof, and fold the half-rectangular part after folding along the diagonal line thereof, as shown in Figure 7 ; meanwhile, the first paper part is bent at 90° relative to the second paper part along the horizontal line; wherein the diagonal directions of all the diagonal lines are consistent;

[0034] S13, use glue to bond the folded parts and the butt joint parts, and then shape to obtain an air-tight film folding piece made of a whole air-tight film, wherein the first paper surface is folded into a cylindrical part (as shown in Figure 8 ) and the second paper surface is folded into a flat surface (as shown in Figure 9 ).

[0035] In Figure 5 , the horizontal line crease of the air-tight film paper tape is X-X', the cutting seam opening positions are point 1 to point 3, point 4 to point 6, point 7 to point 9, and the double-dot dashed lines are all creases.
