[0012] In a preferred embodiment, an upper corrosion-resistant layer is disposed on the upper end of the corrosion-resistant layer, and a lower corrosion-resistant layer is disposed on the lower end of the upper corrosion-resistant layer.

[0013] By adopting the above technical solution, the overall corrosion resistance of the sealing strip body can be increased and the service life of the sealing strip body can be extended.
