[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] The present utility model provides a double-sided tape for automotive sealing as shown in Figures 1-6 , including a tape body 1 for automotive sealing. The tape body 1 includes a sealing strip 101. A waterproof layer 102 is provided on the top of the sealing strip 101. A wear-resistant layer 103 is provided on the top of the waterproof layer 102. A reflective layer 104 is provided on the top of the wear-resistant layer 103. An adhesive layer 105 is provided on the bottom of the sealing strip 101. The wear-resistant layer 103 is made of thermoplastic polyurethane, and the adhesive layer 105 is a pressure-sensitive adhesive;

[0027] The adhesive layer 105 of the present utility model is a pressure-sensitive adhesive. A pressure-sensitive adhesive is a special adhesive that can achieve adhesion under slight pressure. This characteristic makes the pressure-sensitive adhesive very suitable for adhesive products such as tapes. The tape body 1 is adhered to the vehicle through the adhesive layer 105;

[0028] The wear-resistant layer 103 in the present utility model is made of thermoplastic polyurethane. Thermoplastic polyurethane is an important thermoplastic elastomer material. Thermoplastic polyurethane has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance, and has good processing performance. By setting the wear-resistant layer 103, the wear resistance of the tape body 1 can be increased, preventing the tape body 1 from being worn and damaged, and extending the service life of the tape body 1.

[0029] As Figure 5 shown, the sealing strip 101 is made of ethylene propylene diene monomer material. The sealing strip 101 in the present utility model is made of ethylene propylene diene monomer material. The ethylene propylene diene monomer material enhances the aging resistance properties of the tape such as ozone resistance, heat resistance, and weather resistance, ensuring the effective use of the tape body 1 in the automotive range and extending the service life of the tape body 1.

[0030] As Figure 5 shown, the waterproof layer 102 is a polymer waterproof film. The waterproof layer 102 in the present utility model is a polymer waterproof film. The polymer waterproof film is usually made of polymer polymers and has excellent water resistance, weather resistance, and chemical corrosion resistance. By setting the waterproof layer 102, external moisture can be prevented from entering the vehicle interior to protect the vehicle.

[0031] As Figure 5 shown, the reflective layer 104 is a chemical fiber cloth. The reflective layer 104 in the present utility model is a chemical fiber cloth. The chemical fiber cloth is a material with ordinary brightness and high brightness and has good reflective performance. When people shine a light on it, the reflective layer 104 will reflect light, making it convenient for people to find the tape body 1.

[0032] As Figure 6 shown, a limiting mechanism 2 for limiting the tape body 1 is provided outside the tape body 1. The limiting mechanism 2 includes two limiting plates 201 respectively arranged on both sides of the tape body 1. A same limiting rod 202 is penetrated between the two limiting plates 201. A first threaded hole 203 is opened on one side of the limiting rod 202. A first threaded rod 204 is threadedly connected inside the first threaded hole 203. One end of the first threaded rod 204 penetrates through the limiting rod 202 and extends out of one end of the limiting rod 202. A first handle 205 is fixedly arranged at one end of the first threaded rod 204 extending out of the limiting rod 202;

[0033] Insert one end of the limiting rod 202 into the inside of one of the limiting plates 201, then insert the tape body 1 outside the limiting rod 202, and then insert the other limiting plate 201 into one end of the limiting rod 202. Rotate the first handle 205, and use the first handle 205 to rotate the first threaded rod 204 into the first threaded hole 203. The first threaded rod 204 can install the two limiting plates 201 on both sides of the tape body 1 respectively. The tape body 1 can be limited by the two limiting plates 201 to prevent the tape body 1 from falling off.

[0034] As Figure 6 shown, a cutting mechanism 3 for cutting the tape body 1 is provided on one side of the limiting rod 202. The cutting mechanism 3 includes a second threaded hole 301 opened at one end of the limiting rod 202. A cutting knife 302 for cutting the tape body 1 is provided inside the second threaded hole 301. One end of the cutting knife 302 is fixedly provided with a second threaded rod 303. The second threaded rod 303 is threadedly connected to the second threaded hole 301. One end of the second threaded rod 303 penetrates through the limiting rod 202 and extends out of one end of the limiting rod 202. One end of the second threaded rod 303 extending out of one end of the limiting rod 202 is fixedly provided with a second handle 304;

[0035] Rotate the second handle 304, and use the second handle 304 to turn the second threaded rod 303 out of the second threaded hole 301. The second threaded rod 303 takes out the cutting knife 302 from the second threaded hole 301. The tape body 1 can be cut by the cutting knife 302, which improves the practicability of the present invention.

[0036] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
