[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0022] like Figure 1-Figure 6As shown, a high corrosion resistance double-sided adhesive tape proposed in an embodiment of the present application includes a double-sided adhesive body, the double-sided adhesive body includes a substrate 1, adhesive layers 2 are arranged on opposite sides of the substrate 1, release papers 3 are arranged on opposite sides of the two adhesive layers 2, anti-corrosion layers 4 are arranged on opposite sides of the double-sided adhesive body, and waterproof layers 5 are arranged on opposite sides of the two anti-corrosion layers 4. In this embodiment, the anti-corrosion layer 4 is made of fluorine-containing polymer, which is also called fluororesin, a general term for synthetic resins containing fluorine atoms in the molecules, and has high heat resistance, chemical corrosion resistance, durability and weather resistance. The waterproof layer 5 is made of butyl rubber, which has good waterproof properties. The width of the anti-corrosion layer 4 is the same as that of the waterproof layer 5, the total thickness of the substrate 1 and the two adhesive layers 2 is the same as the width of the anti-corrosion layer 4, the anti-corrosion layer 4 covers the sides of the substrate 1 and the two adhesive layers 2, and the release paper 3 covers the sides of the anti-corrosion layer 4 and the waterproof layer 5.
[0023] When not in use, the release paper 3 is located on the adhesive layer 2 and covers the sides of the anti-corrosion layer 4 and the waterproof layer 5. When in use, the release paper 3 is torn off the adhesive layer 2 so that the adhesive layer 2 is bonded to the bonding surface. The two anti-corrosion layers 4 are provided to prevent the opposite sides of the substrate 1 from being directly exposed to the outside and causing corrosion, thereby improving the overall corrosion resistance. The two waterproof layers 5 are provided to prevent the opposite sides of the adhesive layer 2 from being directly exposed to the outside and causing the viscosity to decrease when in contact with water or in a humid environment, thereby ensuring the service life of the double-sided tape.
[0024] In summary, the present application can prevent the opposite sides of the substrate 1 from being directly exposed to the outside and causing corrosion by setting two anti-corrosion layers 4, thereby improving the overall corrosion resistance. The application can prevent the opposite sides of the adhesive layer 2 from being directly exposed to the outside and causing the viscosity to decrease when encountering water or in a humid environment by setting two waterproof layers 5, thereby ensuring the service life of the double-sided tape, and is therefore more practical.
[0025] like Figure 2 As shown, in some embodiments, an adhesive strip 6 is provided on the anti-corrosion layer 4 and the waterproof layer 5, and the release paper 3 covers the adhesive strip 6;
[0026] Referring to the above, by providing the adhesive strip 6, not only the connection strength between the anti-corrosion layer 4 and the waterproof layer 5 can be improved, but also when the release paper 3 is torn off, the adhesive strip 6 will also adhere to the bonding surface, thereby improving the overall bonding strength.
[0027] like Figure 5 As shown, in some embodiments, the anti-corrosion layer 4 and the waterproof layer 5 are both formed with grooves 7, and the two grooves 7 are enclosed to form a receiving groove, and the adhesive strip 6 is located in the receiving groove;
[0028] With reference to the above, the adhesive strip 6 is accommodated by the accommodating groove to prevent the adhesive strip 6 from being directly exposed to the outside and causing the adhesiveness to be reduced when it comes into contact with water or in a humid environment.
[0029] like Figure 3 As shown, in some embodiments, a reinforcing mesh 8 is provided on opposite sides of the substrate 1. In this embodiment, the reinforcing mesh 8 is made of polyester fiber. Polyester fiber has the advantages of high modulus, high strength, good elasticity, good shape retention and heat resistance, etc., which can improve the structural strength and tensile strength of the reinforcing mesh 8. The reinforcing mesh 8 is composed of a plurality of continuously distributed honeycomb structures. The honeycomb structure has excellent structural strength and stability, which can enable the reinforcing mesh 8 to adapt to lateral and longitudinal tensile forces, thereby improving the structural strength and tensile strength of the reinforcing mesh 8.
[0030] As mentioned above, by providing the reinforcement net 8, the overall tensile strength of the double-sided tape can be improved, and the tape is less likely to deform and break after being stretched.
[0031] like Figure 4 As shown, in some embodiments, the opposite sides of the substrate 1 are configured with embedding grooves 9 corresponding to the shape of the reinforcing mesh 8, and the reinforcing mesh 8 is embedded in the embedding grooves 9;
[0032] With reference to the above, the design of embedding the groove 9 can not only improve the connection strength between the substrate 1 and the reinforcing net 8, but also achieve hiding of the reinforcing net 8, which is beneficial to reducing the overall thickness of the double-sided tape.
[0033] like Figure 6 As shown, in some embodiments, a plurality of evenly distributed cavities 10 are constructed in the substrate 1, and a reinforcing column 11 is disposed in the cavity 10, and the reinforcing column 11 is fixed in the cavity 10;
[0034] With reference to the above, when in use, the cavity 10 and the reinforcing column 11 cooperate to improve the overall compression resistance of the double-sided tape, so that the double-sided tape is not easily deformed when under pressure.
[0035] like Figure 6 As shown, in some embodiments, the cavity 10 and the reinforcing column 11 have the same shape and are both honeycomb-shaped. The honeycomb structure has excellent structural strength and stability, and can further improve the overall compressive resistance of the double-sided tape.
[0036] like Figure 2-Figure 5 As shown, in some embodiments, the thickness of the anti-corrosion layer 4 and the waterproof layer 5 are the same and are both 5-10 μm. If the thickness of the anti-corrosion layer 4 and the waterproof layer 5 is greater than 10 μm, the overall weight and production cost of the double-sided tape will increase. If the thickness of the anti-corrosion layer 4 and the waterproof layer 5 is less than 5 μm, the protection effect will be affected to a certain extent.
[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
