Abstract
Description
Technical Field
[0001] This utility model relates to the field of double-sided adhesive technology, and in particular to a double-sided adhesive that is easy to splice. Background Technology
[0002] Double-sided tape is a type of adhesive tape that is sticky on both sides and is widely used in various scenarios, such as handicrafts, home decoration, office stationery, and electronic equipment assembly.
[0003] Double-sided tape has strong adhesion on both sides, enabling it to firmly adhere to various material surfaces such as paper, plastic, and metal. For example, Chinese Patent Publication No. CN217377757U provides a modular, interlocking double-sided tape, belonging to the technical field of double-sided tape. It includes a first double-sided tape, a second double-sided tape, and a connecting piece. Both the first and second double-sided tapes are connected to the connecting piece. The connecting piece has a first toothed groove on one side facing both the first and second double-sided tapes, and second toothed grooves on both sides of the first and second double-sided tapes, with the first and second toothed grooves fitting together. This modular, interlocking double-sided tape allows adjacent double-sided tapes to form a modular combination, and the user can easily peel off individual tapes as needed.
[0004] Currently, conventional double-sided tapes are mostly based on a single base layer. In particular, to increase the overall flexibility of the double-sided tape, foam materials are used to make the base layer. However, the disadvantage of foam materials is that they may age, deform under compression or break when used for a long time or exposed to harsh environments. Their tensile strength is usually low, which means that the double-sided tape may break or lose its adhesive force when subjected to large tensile forces. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a double-sided adhesive that is easy to splice.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a double-sided adhesive that is easy to splice, including an adhesive body, wherein the surface of the adhesive body is provided with tearable segments, and the surface of the tearable segments is provided with perforated holes;
[0008] The colloid comprises a base layer, a strong adhesive layer, a reinforcing layer, an adhesive layer one, a release layer one, an adhesive layer two, and a release layer two. A strong adhesive layer is bonded to one side of the base layer, a reinforcing layer is bonded to the other side of the strong adhesive layer, adhesive layer one is bonded to the other side of the reinforcing layer, release layer one is bonded to the other side of adhesive layer one, adhesive layer two is bonded to the other side of the base layer, and release layer two is bonded to the other side of adhesive layer two.
[0009] The reinforcing layer has protrusions on both sides, and the protrusions and the reinforcing layer are an integral structure.
[0010] The base layer comprises an anti-UV layer and a core layer, with the anti-UV layer coated on the surface of the core layer.
[0011] In detail, the strong adhesive layer is made of resin adhesive material.
[0012] In detail, the reinforcing layer is made of acrylic fiber material.
[0013] In detail, both adhesive layer one and adhesive layer two are made of acrylic ester material.
[0014] In detail, both release layer one and release layer two are made of polyethylene material.
[0015] In detail, the UV-resistant layer is made of salicylic acid ester material.
[0016] In detail, the central layer is made of kraft paper material.
[0017] The design scheme proposed in this utility model has the following beneficial effects in application:
[0018] 1. This solution improves ease of use and flexibility, specifically as follows:
[0019] This double-sided tape design significantly improves ease of use and flexibility by incorporating tearable segments and perforations. The tearable segments are located on the center layer and are thinner than the center layer, with tearable notches at both ends. This allows users to easily segment the tape during use, facilitating splicing according to actual needs. The perforation design reduces the connecting area of the tearable segments, thereby reducing the resistance when tearing and making the segmentation process smoother.
[0020] 2. This solution also enhances bond strength and durability, specifically:
[0021] This double-sided adhesive, through its carefully designed multi-layer structure, significantly enhances bonding strength and durability. The strong adhesive layer, made of resin, boasts extremely high bonding strength, suitable for permanently fixing objects and ensuring a firm connection between the base layer and the reinforcing layer. The reinforcing layer, made of acrylic fiber, possesses excellent tensile strength, effectively improving the overall tear resistance of the adhesive and making it less prone to breakage under external forces. Adhesive layers one and two, made of acrylic ester, offer excellent transparency, weather resistance, and chemical resistance, ensuring stable bonding performance in various environments. Release layers one and two, made of polyethylene, provide excellent waterproof and moisture-proof properties, effectively protecting the structure of the bonded area and extending its service life. The UV-resistant layer, made of salicylic acid ester, absorbs ultraviolet rays and converts them into heat energy, preventing UV penetration and thus providing anti-aging protection for the core layer, ensuring the adhesive maintains its long-term performance even when used outdoors. The core layer, made of kraft paper, offers excellent tear resistance and water resistance, suitable for various indoor and outdoor applications, further enhancing the adhesive's durability and applicability.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Reference Figures 1-4A double-sided adhesive that is easy to splice includes an adhesive body 1. The surface of the adhesive body 1 is provided with a tearable segment 11. The surface of the tearable segment 11 is provided with a hollow hole 12. The tearable segment 11 is located on a central layer 1012, and the thickness of the tearable segment 11 is less than the thickness of the central layer 1012. The front and rear ends of the tearable segment 11 are provided with tearable notches, which facilitates quick segmentation when the entire adhesive body 1 is segmented and spliced. The hollow hole 12 can reduce the connection area of the tearable segment 11, thereby increasing the resistance to the tearing process.
[0029] The colloid 1 comprises a base layer 101, a strong adhesive layer 102, a reinforcing layer 103, an adhesive layer 104, a release layer 105, an adhesive layer 2 106, and a release layer 2 107. The strong adhesive layer 102 is bonded to one side of the base layer 101, the reinforcing layer 103 is bonded to the other side of the strong adhesive layer 102, the adhesive layer 104 is bonded to the other side of the reinforcing layer 103, the release layer 105 is bonded to the other side of the adhesive layer 104, the adhesive layer 2 106 is bonded to the other side of the base layer 101, and the release layer 2 107 is bonded to the other side of the adhesive layer 2 106.
[0030] The reinforcing layer 103 has protrusions 1031 on both sides. The protrusions 1031 and the reinforcing layer 103 are an integral structure. When the protrusions 1031 come into contact with the strong adhesive layer 102 and the adhesive layer 104 respectively, the bonding area is increased and the bonding effect is enhanced.
[0031] The base layer 101 includes an anti-ultraviolet layer 1011 and a core layer 1012, with the anti-ultraviolet layer 1011 coated on the surface of the core layer 1012.
[0032] It should be further noted that the strong adhesive layer 102 is made of resin adhesive material. Resin adhesive has a large bonding strength and can be used for bonding some permanently fixed objects, thereby improving the bonding stability between the base layer 101 and the reinforcing layer 103.
[0033] It should be further noted that the reinforcing layer 103 is made of acrylic fiber material. As the base layer structure of the fabric, it has good tensile strength and improves the tear resistance of the entire colloid 1.
[0034] It should be further noted that both adhesive layer 104 and adhesive layer 106 are made of acrylic ester material, which has good transparency, weather resistance and chemical resistance, and is widely used in double-sided tape structures.
[0035] It should be further noted that both release layer 105 and release layer 107 are made of polyethylene material, which has good waterproof and moisture-proof properties and can provide good protection for the structure of the bonded parts.
[0036] It should be further noted that the UV-resistant layer 1011 is made of salicylic acid ester material, which can absorb ultraviolet rays and convert them into heat energy, thereby preventing ultraviolet rays from penetrating the coating and thus providing anti-aging protection for the central layer 1012.
[0037] It should be further noted that the core layer 1012 is made of kraft paper, a tough and durable paper with good tear resistance and water resistance, suitable for various indoor and outdoor applications.
[0038] Working principle: This double-sided tape design significantly improves ease of use and flexibility by incorporating tearable segments 11 and perforated holes 12. The tearable segments 11 are located on the central layer 1012 and are thinner than the central layer 1012. Tearable notches are also provided at both ends, allowing users to easily segment the adhesive 1 for easy splicing according to actual needs. The perforated holes 12 reduce the connection area of the tearable segments 11, thereby reducing tearing resistance and making the segmentation process smoother. This design is particularly suitable for scenarios requiring frequent adjustments or changes in bonding positions, such as temporary fixing or display setups. Users do not need scissors or other tools; they can simply tear the segments to complete the segmentation, greatly improving work efficiency and user experience. Furthermore, the segmented adhesive 1 maintains good adhesive performance, ensuring the strength and stability of the bond.
[0039] This double-sided adhesive, through its carefully designed multi-layer structure, significantly enhances bonding strength and durability. Adhesive 1 comprises a base layer 101, a strong adhesive layer 102, a reinforcing layer 103, an adhesive layer one 104, a release layer one 105, an adhesive layer two 106, and a release layer two 107. Each layer undergoes special treatment to ensure superior overall performance. The strong adhesive layer 102, made of resin material, possesses extremely high bonding strength, suitable for permanently fixing objects, ensuring a strong connection between the base layer 101 and the reinforcing layer 103. The reinforcing layer 103, made of acrylic fiber material, has good tensile strength, effectively improving the tear resistance of the entire adhesive 1, making it less prone to breakage under external forces. Adhesive layers one 104 and two 106 are made of acrylic fiber. Made of acrylic acid ester material, it has good transparency, weather resistance and chemical resistance, ensuring stable adhesion in various environments. Release layer 105 and release layer 2 107 are made of polyethylene material, which has good waterproof and moisture-proof properties, effectively protecting the structure of the bonded parts and extending service life. The UV-resistant layer 1011 is made of salicylic acid ester material, which can absorb ultraviolet rays and convert them into heat energy, preventing ultraviolet rays from penetrating the coating, thereby providing anti-aging protection for the core layer 1012 and ensuring that the colloid 1 can maintain its long-term performance when used outdoors. The core layer 1012 is made of kraft paper material, which has good tear resistance and water resistance, and is suitable for various indoor and outdoor applications, further enhancing the durability and applicability of the colloid 1.
