Description

Technical Field

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

[0002] Double-sided tape is an adhesive that has a sticky substance, usually glue or pressure-sensitive adhesive, on both sides. This tape can be used in a variety of applications, such as securing objects, hanging pictures, applying labels, closing packages, etc. Double-sided tape tends to be more powerful than single-sided tape because it can adhere to two surfaces at the same time, providing a stronger bond.

[0003] The existing double-sided tape generally consists of a base material layer, an adhesive layer and a protective layer, wherein the adhesive layer is used to adhere objects, and the protective layer is used to protect the adhesive layer from contamination. Therefore, the overall tear resistance of the double-sided tape is poor. For this reason, we propose a tear-resistant double-sided tape. Utility Model Content

[0004] The purpose of the utility model is to provide a tear-resistant double-sided adhesive tape to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Preferably, a first release paper is arranged on the middle upper surface of the adhesive layer at the top of the substrate layer, a second release paper is arranged on both sides of the adhesive layer at the top of the substrate layer, a first pulling tape is arranged on the upper surface of the end of the first release paper, and a second pulling tape is arranged on the side of the second release paper close to the first pulling tape;

[0013] 1. This tear-resistant double-sided tape is used in combination with an adhesive layer and a reinforcement layer.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0021] like Figure 1-3 As shown, a technical solution provided by the utility model:

[0022] A tear-resistant double-sided tape comprises a substrate layer 1, adhesive layers 2 are arranged on both sides of the substrate layer 1, an easy-tear mechanism 3 is arranged on the upper surface of the adhesive layer 2 at the top of the substrate layer 1, the easy-tear mechanism 3 comprises a first release paper 301, a second release paper 302 and a first pulling tape 303, and a reinforcing layer 4 is arranged on the inner side of the adhesive layer 2; the substrate layer 1 is made of a high-strength polyester film or a polyimide film, and the reinforcing layer 4 is made of glass fiber, polyester fiber or nylon fiber;

[0023] In this embodiment, a reinforcing layer 4 is provided inside the adhesive layer 2. The reinforcing layer 4 uses glass fiber, polyester fiber or nylon fiber. Embedding the reinforcing glass fiber, polyester fiber or nylon fiber into the adhesive layer 2 can effectively enhance the tensile properties of the double-sided tape, and the fiber can provide additional support and strength during stretching, reducing the risk of tearing.

[0024] like Figure 1 and Figure 3 As shown, a first release paper 301 is arranged on the middle upper surface of the adhesive layer 2 at the top of the substrate layer 1, and second release papers 302 are arranged on both sides of the adhesive layer 2 at the top of the substrate layer 1, and a first pulling tape 303 is arranged on the upper surface of the end of the first release paper 301, and a second pulling tape 5 is arranged on the side of the second release paper 302 close to the first pulling tape 303; two second release papers 302 are integrally formed at one end close to the first pulling tape 303;

[0025] In this embodiment, when double-sided tape is needed, first pinch the first pulling tape 303, and then pull the first release paper 301 through the first pulling tape 303, so that the first release paper 301 is torn first, and then pinch the second pulling tape 5, and pull the second release paper 302 through the second pulling tape 5, so that the second release paper 302 is torn again. By tearing twice, the protective paper can be prevented from being broken when tearing once.

[0026] like Figure 1 As shown, cutting seams 6 are provided between the two sides of the first release paper 301 and the second release paper 302;

[0027] In this embodiment, the cutting seams 6 provided between the two sides of the first release paper 301 and the second release paper 302 facilitate rapid separation of the first release paper 301 and the second release paper 302 when tearing.

[0028] like Figure 3 As shown, the first release paper 301 and the second release paper 302 are made of silicon-coated paper or polytetrafluoroethylene-coated paper;

[0029] In this embodiment, a layer of silicone rubber is coated on the surface of the first release paper 301 and the second release paper 302 to make their surfaces smooth and not easy to adhere to other materials. Polytetrafluoroethylene coated paper is often used in high temperature environments. Polytetrafluoroethylene coated paper is a material with excellent high temperature resistance and non-stick properties.

[0030] Working principle: The substrate layer 1 of the double-sided tape is made of high-strength polyester film or polyimide film. The thicker substrate layer 1 can withstand greater tensile force and tearing force, thereby improving the durability of the double-sided tape. A reinforcement layer 4 is arranged inside the adhesive layer 2. The reinforcement layer 4 is made of glass fiber, polyester fiber or nylon fiber. Embedding the reinforcing glass fiber, polyester fiber or nylon fiber into the adhesive layer 2 can effectively enhance the tensile properties of the double-sided tape, and the fiber can provide additional support and strength during stretching, reducing the risk of tearing; when the double-sided tape is needed, first pinch the first pulling tape 303, and then pull the first release paper 301 through the first pulling tape 303, so that the first release paper 301 is torn first, and then pinch the second pulling tape 5, and pull the second release paper 302 through the second pulling tape 5, so that the second release paper 302 is torn again. By tearing twice, the protective paper breakage caused by one-time tearing can be avoided.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
