Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive materials technology, and in particular to double-sided self-adhesive hook and loop fasteners with a peelable adhesive backing structure. Background Technology
[0002] In the home, these stickers can be used to secure curtain edges and sofa cushions; their position can be adjusted at any time after application, and no adhesive residue remains on the wall when removed. In children's rooms, they can be used to secure picture book shelves and provide anti-collision stickers, allowing parents to easily change their location to suit their child's evolving needs. In office settings, they can be used for document categorization labels and cable management, and repeated application will not damage the desktop.
[0003] Some existing double-sided self-adhesive hook and loop fasteners achieve adhesion through the interaction of the hook and loop sides, which is suitable for fixing between similar materials. Adhesive-backed hook and loop fasteners add an adhesive backing layer to the traditional structure, which can be directly pasted onto smooth surfaces and can achieve multi-directional adhesion and fixation, making them suitable for scenarios that require quick fixation.
[0004] However, in actual use, it is difficult to position accurately, and it is easy to deviate or skew when pasting, which affects the fixing effect and aesthetics. Adjusting the position requires repeated peeling and re-pasting, which can easily lead to a decrease in the adhesive strength. For scenarios that require symmetrical or regular arrangement, it is difficult to ensure consistency, reducing the ease of use and scenario adaptability. In order to address the above problems, we now propose a double-sided self-adhesive hook and loop fastener with a peelable adhesive backing structure. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3This utility model provides an embodiment of a double-sided self-adhesive hook and loop fastener with a peelable adhesive backing, comprising a male adhesive patch 1, the outer surface of which is provided with a hook surface 2, which is a fine hook-shaped protrusion structure evenly distributed on one side surface of the male adhesive patch 1, the protrusion tips being barbed, providing strong adhesion; a female adhesive patch 4 is detachably connected to the outer surface of the male adhesive patch 1, the outer surface of which is provided with a rough surface 5, the female adhesive patch 4 being a rectangular sheet structure matching the size of the male adhesive patch 1, and the material... The surface is soft, and the nap 5 is a dense fiber pile structure that evenly covers one side of the female sticker 4 corresponding to the hook surface 2. The pile is soft and elastic. The male sticker 1 is fixedly connected to the outside of a positioning mechanism, and the female sticker 4 is fixedly connected to the outside of a protective mechanism. The positioning mechanism includes a positioning strip 3, which is a long strip-shaped protrusion with a semi-circular cross-section. It is set on the outside of the hook surface 2 along the edge length direction of the male sticker 1. The height of the protrusion is slightly lower than the hook-shaped protrusion of the hook surface 2. The outside of the positioning strip 3 is set on the outside of the male sticker 1.
[0033] The female adhesive 4 has a positioning groove 6 on its outside. The positioning groove 6 is a long strip groove with a semi-circular cross-section. It is opened on the outside of the rough surface 5 along the edge length direction of the female adhesive 4. The size of the groove is adapted to the positioning strip 3. The positioning strip 3 can be embedded in the positioning groove 6. The female adhesive 4 has a backing adhesive 7 on its outside. The backing adhesive 7 is a uniformly coated adhesive layer that covers the side of the female adhesive 4 away from the rough surface 5. The adhesive layer is covered with release paper. The backing adhesive 7 is fixedly connected to the outside of the release ear 8. The female adhesive 4 has an anti-bubbling component inside. The anti-bubbling component includes an air vent 9. The air vent 9 is opened on the outside of the female adhesive 4. Multiple partitions 10 are fixedly connected inside the air vent 9. The partitions 10 are thin sheet structures that are evenly distributed perpendicular to the length direction of the air vent 9. One end is connected to the inner wall of the air vent 9, and the other end extends into the groove, dividing the air vent 9 into multiple small areas.
[0034] Reference Figures 3 to 5 The protective mechanism includes an isolation layer 12, which is a thin sheet structure that completely covers the side of the mother patch 4 away from the rough surface 5. The edge is aligned with the edge of the mother patch 4, and the surface is flat and smooth. The isolation layer 12 is fixedly connected to the outside of the mother patch 4. A wear-resistant layer 13 is fixedly connected to the outside of the isolation layer 12. The wear-resistant layer 13 is tough and tightly adheres to the outer surface of the isolation layer 12. The surface has a fine texture, which can enhance the wear resistance of the surface. A heat-resistant layer 14 is fixedly connected to the outside of the wear-resistant layer 13. The heat-resistant layer 14 covers the outer surface of the wear-resistant layer 13. The whole is a uniform sheet shape without wrinkles or bubbles. It can maintain stable performance within a certain temperature range. A flame-retardant layer 15 is fixedly connected to the outside of the heat-resistant layer 14. The flame-retardant layer 15 covers the outer surface of the heat-resistant layer 14 flatly, and the edge is consistent with the edge of the heat-resistant layer 14. It has a good flame-retardant effect.
[0035] The male sticker 1 has an external venting groove 2 11, which is a long strip-shaped groove. It is opened on the side surface of the male sticker 1 where the hook surface 2 is set, and is evenly distributed along the width direction of the male sticker 1. The groove is shallow and matches the height of the protrusion of the hook surface 2. It can expel air when the male sticker 1 and the female sticker 4 are attached. The male sticker 1 is detachably connected to the outside of the female sticker 4. The hook surface 2 of the male sticker 1 and the rough surface 5 of the female sticker 4 are in contact and attached to each other. The barbed protrusion of the hook surface 2 hooks the fibers of the rough surface 5. It can be separated and attached during the attachment process. The external backing adhesive 7 is set on the outside of the male sticker 1. The external backing adhesive 7 is fixedly connected to the outside of the peeling ear 8. The external positioning groove 6 is opened on the outside of the female sticker 4. The external positioning strip 3 is slidably connected to the outside of the female sticker 4.
[0036] Working principle: By pinching the release ear 8 and pulling it outward, the release paper on the surface of the adhesive backing 7 is peeled off from the adhesive layer surface along with the release ear 8. The female sticker 4 is pasted to the target position through the adhesive backing 7. Press the surface of the female sticker 4, and the air in the first vent groove 9 is discharged through the small area separated by the partition 10 to avoid the formation of air bubbles. The positioning strip 3 of the male sticker 1 is aligned with the positioning groove 6 of the female sticker 4 and slides along the length of the positioning groove 6. The positioning strip 3 is embedded in the positioning groove 6, pushing the male sticker 1 closer to the female sticker 4. The barbed protrusion of the hook surface 2 contacts the fiber fluff of the napped surface 5. During the process of the male sticker 1 and the female sticker 4 being bonded, the second vent groove 11 discharges the air between the contact surfaces.
[0037] When the peeling ear 8 is pulled, the release paper of the adhesive 7 detaches from the adhesive layer, allowing the mother sticker 4 to adhere to the target surface through the adhesive 7. This causes the isolation layer 12 to adhere tightly to the outside of the mother sticker 4, and the wear-resistant layer 13 to cover it, maintaining the integrity of the fine surface texture. Consequently, the heat-resistant layer 14 is flatly adhered to the wear-resistant layer 13 without wrinkles or bubbles. The edge of the flame-retardant layer 15 is aligned with the heat-resistant layer 14 and is in a naturally extended state. The partition 10 in the venting groove 9 remains vertically separated, and the edge of the mother sticker 4 completely overlaps with the edges of each layer of the protective mechanism without any offset or misalignment.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
