[0022] See also Figure 1-3 A double-sided tape with high bonding strength includes a paper tube 1, a tape body 2 is wound around the outer side of the paper tube 1, the tape body 2 includes a release film layer 21, a lower adhesive layer 22, a substrate layer 23 and an upper adhesive layer 24, the substrate layer 23 includes a waterproof layer 232, a tensile layer 233 and a high temperature resistant layer 234, and adhesive storage grooves 231 are provided on the top and bottom of the substrate layer 23.

[0023] The lower adhesive layer 22 is bonded to the top of the release film layer 21 , the substrate layer 23 is bonded to the top of the lower adhesive layer 22 , and the upper adhesive layer 24 is bonded to the top of the substrate layer 23 .

[0024] The waterproof layer 232 is made of a polypropylene fiber layer, and the mesh number of the polypropylene fiber layer is between 220 meshes and 500 meshes.

[0025] Through the above technical solution, the double-sided tape has waterproof capability through the provision of the waterproof layer 232.

[0026] The material of the tensile layer 233 is a polyacrylonitrile fiber layer, and the thickness of the tensile layer 233 is between 0.5 times and 0.7 times the thickness of the base material layer 23 .

[0027] Through the above technical solution, the tensile strength of the double-sided tape is improved by setting the tensile layer 233, which prevents the double-sided tape from being easily pulled and deformed during use, thereby reducing the bonding strength.

[0028] There are multiple glue storage grooves 231 , and the longitudinal section of the glue storage groove 231 is V-shaped.

[0029] Through the above technical solution, more adhesive can be added through the provision of the adhesive storage groove 231.

[0032] When in use, pull out the tape body 2 so that one end of the upper adhesive layer 24 adheres to the surface of the object, and at the same time press the adhesive end with a finger, and the finger moves along with the pulling out of the tape body 2. At this time, the glue storage groove 231 can be smoothed, thereby expanding the bonding range of the substrate layer 23, and the excess adhesive stored in the glue storage groove 231 can be discharged and enter the corresponding lower adhesive layer 22 and upper adhesive layer 24 respectively, thereby expanding the amount of adhesive, thereby greatly improving the bonding strength of the double-sided tape. The provision of the waterproof layer 232 makes the double-sided tape waterproof. The provision of the anti-tension layer 233 improves the tensile strength of the double-sided tape, thereby preventing the double-sided tape from being easily pulled and deformed during use, thereby reducing the bonding strength. The provision of the high-temperature resistant layer 234 improves the high-temperature resistant strength of the double-sided tape and expands its scope of application.
