Title:
HYDROPHOBIC PATTERNED ADHESIVE TAPE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/040627
Kind Code:

Abstract:
Hydrophobic patterned adhesive tape (100) and a manufacturing method therefor. The hydrophobic patterned adhesive tape (100) comprises: a patterned layer (10) having an upper surface (11) and a lower surface (12), the patterned layer (10) having a stepped structure; a hydrophobic film layer (20) provided on the upper surface (11) of the patterned layer (10); an adhesive layer (30) disposed on the lower surface (12) of the patterned layer (10); a release film layer (40) provided on the adhesive layer (30); and a hydrophobic protective layer (50) provided on the hydrophobic film layer (20). The stepped structure of the patterned layer (10) allows the adhesive layer (30) arranged on the lower surface (12) of the patterned layer (10) to bond to and cover an adhesive surface (201) of a different height located on a component (200) to be sealed, thereby sealing a gap (300) between different-height upper end surfaces (2011) of two adjacent components (200) to be sealed. Thus, the application range of the hydrophobic patterned adhesive tape (100) is expanded. At the same time, the invention solves the problem in the related art whereby adhesive tape having a flat belt structure has a poor sealing effect for a gap (300) between two different-height components (200) to be sealed.
