However, most of the polypropylene double-sided tapes on the market currently have relatively single functionality, which leads to their poor practicality and difficulty in adapting to various occasions, resulting in certain limitations in the use of the entire polypropylene double-sided tape.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: comprising a tape body and a waterproof layer, a first adhesive layer is connected to the top inner side of the tape body, and an anti-corrosion layer is connected to the bottom of the first adhesive layer, the waterproof layer is connected to the other side of the anti-corrosion layer, a breathable layer is connected to the side of the waterproof layer away from the anti-corrosion layer, and an extension layer is provided at the bottom of the breathable layer, a reinforcing layer is connected to the other side of the extension layer, and an antistatic film layer is connected to the side of the reinforcing layer away from the extension layer, and a second adhesive layer is connected to the bottom of the anti-static film layer.

[0006] As a preferred technical solution of the utility model, warp fibers and weft fibers are evenly distributed on the inner side of the extension layer, and the warp fibers and the weft fibers are woven alternately.

[0007] As a preferred technical solution of the utility model, a reinforcing rib penetrates the inner side of the extension layer, and a first PP fiber and a second PP fiber are equidistantly distributed on the outer surface of the reinforcing rib, and the first PP fiber and the second PP fiber are equidistantly distributed.

[0009] As a preferred technical solution of the utility model, the anti-corrosion layer is attached to the bottom of the first adhesive layer, and the other side of the anti-corrosion layer is attached to the top of the waterproof layer.

[0010] As a preferred technical solution of the present invention, the first PP fiber and the second PP fiber are both wound around the outer surface of the reinforcing ribs, and the reinforcing ribs are distributed in parallel.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. The combination of the anti-corrosion layer and the waterproof layer can improve the functionality of the entire polypropylene double-sided tape, thereby improving the practicality of the entire polypropylene double-sided tape and making it suitable for various environments. Since the internal structure of the anti-corrosion layer is made of anti-corrosion materials, it has a certain anti-corrosion effect, which can improve the anti-corrosion of the entire tape, thereby ensuring that the tape will not be corroded due to long-term use. The internal structure of the waterproof layer is made of waterproof coating, which has a good waterproof effect and can prevent liquid from penetrating into the internal structure of the tape.

[0013] 2. By using the extension layer and the reinforcement layer in combination, the strength of the entire tape can be improved, thereby ensuring that the tape itself has a certain degree of ductility and can be stretched, thereby improving its practicality. Since the internal structure of the extension layer is woven from warp fibers and weft fibers, it has a certain degree of ductility and can be stretched, thereby improving the extension effect of the entire tape itself, and the interior of the reinforcement layer is woven from PP fibers, so its own structure is strong, which can improve the strength of the tape itself.

[0019] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0020] Example 1

[0021] Please refer to Figure 1 As shown, the utility model provides a reinforced polypropylene double-sided tape, comprising a tape body 1 and a waterproof layer 4, the inner top of the tape body 1 is connected with a first adhesive layer 2, and the bottom of the first adhesive layer 2 is connected with an anti-corrosion layer 3, the anti-corrosion layer 3 is attached to the bottom of the first adhesive layer 2, and the other side of the anti-corrosion layer 3 is attached to the top of the waterproof layer 4, the waterproof layer 4 is connected to the other side of the anti-corrosion layer 3, the side of the waterproof layer 4 away from the anti-corrosion layer 3 is connected with a breathable layer 5, and the bottom of the breathable layer 5 is provided with an extension layer 6, the other side of the extension layer 6 is connected with a reinforcing layer 7, and the side of the reinforcing layer 7 away from the extension layer 6 is connected with an antistatic film layer 8, and the bottom of the antistatic film layer 8 is connected with a second adhesive layer 9;

[0022] As a further implementation of this embodiment, Figure 1As shown, the first adhesive layer 2 and the second adhesive layer 9 are provided to make both sides of the tape body 1 have an adhesive effect. Since the tape body 1 is provided with an anti-corrosion layer 3, and the internal structure of the anti-corrosion layer 3 is made of anti-corrosion material, the anti-corrosion layer 3 itself has a good anti-corrosion effect, thereby improving the anti-corrosion property of the entire tape body 1, so as to prevent the internal structure of the tape body 1 from being corroded due to long-term use, thereby affecting its normal service life. Since the internal structure of the waterproof layer 4 is made of waterproof coating, resin and other materials, it has a certain waterproof effect, thereby preventing external liquid from penetrating into the interior of the tape body 1, causing its internal structure to be eroded by liquid. The provision of the air-permeable layer 5 can improve the air permeability of the entire tape body 1, and the provision of the extension layer 6 and the reinforcement layer 7 can further improve the structural property of the entire tape body 1, improve the strength of the tape body 1, and make it have a certain ductility.

[0023] Example 2

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a reinforced polypropylene double-sided tape, wherein warp fibers 10 and weft fibers 11 are equidistantly distributed on the inner side of the extension layer 6, and the warp fibers 10 and the weft fibers 11 are woven alternately, a reinforcing rib 12 penetrates the inner side of the extension layer 6, and a first PP fiber 13 and a second PP fiber 14 are equidistantly distributed on the outer surface of the reinforcing rib 12, the first PP fiber 13 and the second PP fiber 14 are both wound around the outer surface of the reinforcing rib 12, and the reinforcing ribs 12 are parallelly distributed, the first PP fiber 13 and the second PP fiber 14 are equidistantly distributed, a spinning fiber layer 15 is provided on the inner side of the air permeable layer 5, and air holes 16 are equidistantly distributed in the inner cavity of the spinning fiber layer 15;

[0025] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, since the internal structure of the extension layer 6 is formed by alternating weaving of warp fibers 10 and weft fibers 11, the entire extension layer 6 itself has a certain degree of ductility, so when the tape body 1 is subjected to external tension, it can be extended, thereby preventing the tape body 1 from directly breaking when subjected to tension. Since the internal structure of the reinforcement layer 7 is formed by weaving of reinforcing ribs 12, first PP fibers 13 and second PP fibers 14, the entire reinforcement layer 7 has a strong structural property. Combined with the setting of the extension layer 6, the structural strength of the entire tape body 1 can be further improved to ensure its normal service life. Since the internal structure of the breathable layer 5 is composed of a spun fiber layer 15, it has good air permeability. Combined with the setting of multiple air holes 16, the air permeability of the entire tape body 1 can be further improved.
