Description

Technical Field

[0001] The utility model relates to the technical field of double-sided adhesive tapes, in particular to an anti-warping double-sided adhesive tape. Background Art

[0002] Double-sided tape is an adhesive with a sticky substance, typically glue or pressure-sensitive adhesive, coated on both sides. This tape is used in a variety of applications, such as securing objects, hanging pictures, applying labels, and closing packages. Double-sided tape tends to be more adhesive than single-sided tape because it adheres to two surfaces simultaneously, providing a stronger bond.

[0003] When the double-sided tape currently available on the market is adhered to an object, the four sides of the double-sided tape are prone to warping, which affects the adhesion effect of the double-sided tape. The double-sided tape is also prone to fall off from the surface of the object later. For this reason, we propose an anti-warping double-sided tape. Utility Model Content

[0004] The purpose of the present invention is to provide a double-sided adhesive tape that prevents warping, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An anti-warping double-sided tape comprising

[0007] A substrate layer, wherein both sides of the substrate layer are provided with a corrugated layer, and both sides of the corrugated layer away from the substrate layer are provided with an adhesive layer, and the upper surface of the top adhesive layer is provided with a release paper;

[0008] Sealing layers are provided on both sides of the base material layer, the corrugated layer and the adhesive layer. The bottom ends of both sides of the release paper are integrally formed with edge guards, which are provided on the outside of the sealing layer.

[0009] Preferably, a reinforcement layer is provided in the middle of the base material layer, a plurality of ceramic fibers are provided on the inner side of the reinforcement layer, and the plurality of ceramic fibers are arranged crosswise;

[0010] Preferably, the release paper is integrally formed with lace on the outer sides of the top ends of the sealing layers on both sides, and the lace is a semicircular structure;

[0011] Preferably, an adhesion promoter is added to the adhesive layer;

[0012] Preferably, the sealing layer is made of polyurethane foam or foam rubber;

[0013] Preferably, the reinforcement layer is made of thickened polyester film or thickened polyethylene film.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This anti-warping double-sided tape is used in combination with a base layer, a wavy layer and an adhesive layer. A wavy layer is provided between the base layer used in the double-sided tape and the adhesive layers on both sides. The wavy layer has a wavy structure. The use of the wavy structure can increase the contact area between the adhesive layer and the base layer in the double-sided tape, thereby improving the adhesion of the double-sided tape and reducing the possibility of warping.

[0016] 2. This anti-warping double-sided tape is used in combination with a base layer, a corrugated layer, an adhesive layer and a sealing layer. Sealing layers are provided on both sides of the base layer, the corrugated layer and the adhesive layer in the double-sided tape, and the sealing layer is made of polyurethane foam or foam rubber. By adding a sealing layer at the edges of both sides of the double-sided tape, it can prevent the intrusion of air, moisture or other external factors. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "several" means two or more, unless otherwise specifically defined.

[0024] like Figure 1-4 As shown, the utility model provides a technical solution:

[0025] A double-sided tape for preventing warping, comprising a substrate layer 1, a corrugated layer 2 provided on both sides of the substrate layer 1, an adhesive layer 3 provided on the side of the corrugated layer 2 on both sides away from the substrate layer 1, and a release paper 4 provided on the upper surface of the top adhesive layer 3; an adhesion promoter is added to the adhesive layer 3;

[0026] In this embodiment, a wavy layer 2 is provided between the base material layer 1 used in the double-sided tape and the adhesive layers 3 on both sides. The wavy layer 2 has a wavy structure. The use of the wavy structure can increase the contact area between the adhesive layer 3 and the base material layer 1 in the double-sided tape, thereby improving the adhesion of the double-sided tape and reducing the possibility of warping.

[0027] like Figure 2 As shown, sealing layers 5 are provided on both sides of the substrate layer 1, the corrugated layer 2 and the adhesive layer 3. The bottom ends of both sides of the release paper 4 are integrally formed with edge guards 6, which are provided on the outside of the sealing layer 5. The sealing layer 5 is made of polyurethane foam or foam rubber.

[0028] In this embodiment, sealing layers 5 are provided on both sides of the base material layer 1, the corrugated layer 2 and the adhesive layer 3 in the double-sided tape, and the sealing layer 5 is made of polyurethane foam or foam rubber. By adding a sealing layer 5 with sealing properties at the edges of both sides of the double-sided tape, it can prevent the intrusion of air, moisture or other external factors.

[0030] In this embodiment, a reinforcing layer 7 is provided in the middle of the base material layer 1 of the double-sided tape, and a plurality of 8 are arranged in a staggered manner inside the reinforcing layer 7. Ceramic fiber is a high-temperature resistant and corrosion-resistant material, which is suitable for use in high-temperature environments. The staggered arrangement structure can increase the stability and tensile strength of the double-sided tape and prevent warping.

[0031] like Figure 1 As shown, the outer sides of the top ends of the release paper 4 near the sealing layers 5 on both sides are integrally formed with laces 9, and the laces 9 are semicircular in structure;

[0032] In this embodiment, the lace 9 provided on the outer sides of the top ends of the release paper 4 close to the sealing layers 5 on both sides can make it more convenient and faster to tear off the release paper 4.

[0033] Working principle: A wavy layer 2 is provided between the base material layer 1 used in this double-sided tape and the adhesive layers 3 on both sides. The wavy layer 2 is a wavy structure. The use of a wavy structure can increase the contact area between the adhesive layer 3 and the base material layer 1 in the double-sided tape, thereby improving the adhesion of the double-sided tape and reducing the possibility of warping; a sealing layer 5 is provided on both sides of the base material layer 1, the wavy layer 2 and the adhesive layer 3 in this double-sided tape, and the sealing layer 5 uses polyurethane foam or foam rubber. By adding a sealing layer 5 with sealing properties at the edges of both sides of the double-sided tape, air, moisture or other external factors can be prevented from intruding; a reinforcing layer 7 is provided in the middle of the base material layer 1 of this double-sided tape, and a number of 8 are staggered inside the reinforcing layer 7. Ceramic fiber is a high-temperature resistant and corrosion-resistant material, which is suitable for high-temperature environments. The staggered structure can increase the stability and tensile strength of the double-sided tape and prevent warping.
