Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive patch technology, specifically to a water-soluble adhesive patch that can be repeatedly bonded. Background Technology
[0002] Adhesive patches are a new type of bonding solution that solves the problems of inconvenience and environmental pollution associated with traditional adhesives through structural innovation and material optimization. They are especially suitable for scenarios with high requirements for operability and environmental protection.
[0003] Existing surface mount adhesives simply apply adhesive to the substrate and then cover it for protection. After use, the adhesive completely hardens, making it unusable. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a reusable water-soluble adhesive patch, which solves the technical problem that existing adhesive patches completely solidify after use, making them difficult to reuse.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A reusable water-soluble adhesive patch includes a substrate, on which a composite adhesive layer is provided and a protective film is covered.
[0007] The composite adhesive layer includes a separator ball, a lower adhesive layer, and an upper adhesive layer. The separator ball is fixedly connected to the substrate. The lower adhesive layer fills the lower half of the area between the separator balls. The upper adhesive layer fills the upper half of the area between the separator balls and covers the separator balls. A protective film is disposed on top of the upper adhesive layer.
[0008] Furthermore, the top of the substrate is provided with an inlay groove corresponding to the separator ball, and the separator ball is installed on the top of the inlay groove.
[0009] Furthermore, the inlay groove is composed of a plurality of neatly arranged basic grooves, the cross-section of which is either square or regular hexagonal.
[0010] Furthermore, a sealing frame is fixedly connected to the top of the substrate, and a composite adhesive layer is installed inside the sealing frame.
[0011] Furthermore, the separating sphere comprises an upper hemisphere and a lower hemisphere, the interior of the upper hemisphere being filled with pressure-sensitive adhesive and the interior of the lower hemisphere being filled with air.
[0012] Furthermore, the top of the upper hemisphere is fixedly connected with multiple protrusions, one end of which extends movably into the interior of the upper hemisphere.
[0013] By employing the above technical solution, this utility model provides a reusable water-soluble adhesive patch, which has at least the following beneficial effects:
[0014] 1. This utility model uses a composite adhesive layer to distribute and separate the adhesive in multiple locations. The amount of adhesive flowing out from different locations is controlled according to the pressure applied during pasting. After use, the adhesive will not completely solidify, thus achieving the purpose of reusing the adhesive.
[0015] 2. This utility model increases the contact area between the separator ball and the substrate after the separator ball is pressed onto the substrate by setting the inlay groove. The separator ball and the substrate are fixed together by adhesive. Due to the existence of the inlay groove between the separator ball and the substrate, the contact area is increased. Therefore, a larger area of adhesive can be attached between the separator ball and the substrate, thereby improving the firmness of the connection between the separator ball and the substrate by using more adhesive.
[0016] 3. This utility model, through the setting of a separator ball, divides the adhesive in the adhesive patch into three parts: a lower adhesive layer, an upper adhesive layer, and a pressure-sensitive adhesive. Not only can the upper and lower adhesive layers be used separately by utilizing different extrusion forces, but it can also further utilize the pressure-sensitive adhesive's characteristic of triggering adhesion after extrusion. This reduces residue during peeling and supports multiple uses. The protrusions facilitate accelerating the breaking speed of the upper hemisphere during extrusion, making the pressure-sensitive adhesive in the upper hemisphere respond faster during use.

[0023] 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.
[0024] Example
[0025] To achieve the goal of reusing adhesive patches, please refer to... Figures 1-4 This embodiment proposes a reusable water-soluble adhesive patch, including a substrate 1, a composite adhesive layer 2 on the substrate 1, and a protective film 3 covering the composite adhesive layer 2. The composite adhesive layer 2 includes a separator ball 21, a lower adhesive layer 22, and an upper adhesive layer 23. The separator ball 21 is fixedly connected to the substrate 1. The lower adhesive layer 22 fills the lower half of the space between the separator balls 21. The upper adhesive layer 23 fills the upper half of the space between the separator balls 21 and covers the spacer balls 21. The protective film 3 is disposed on the top of the upper adhesive layer 23.
[0026] When using, tear off the protective film 3 and stick the composite adhesive layer 2 towards the bonding position. Since most of the lower adhesive layer 22 is between the separator balls 21, when the composite adhesive layer 2 is pressed against the bonding position, the separator balls 21 will also be squeezed and extended to both sides, further separating the lower adhesive layer 22 and the upper adhesive layer 23. This ensures that most of the lower adhesive layer 22 is blocked and sealed by the separator balls 21, and only the upper adhesive layer 23 comes into contact with the bonding position and cures. When the adhesive patch needs to be reused, remove the adhesive patch from the previous bonding position, move it to the next bonding position, and squeeze it firmly. The lower adhesive layer 22, which is separated by the separator balls 21, will be squeezed out and flow to the bonding position. After the lower adhesive layer 22 cures, the bonding is completed again. The adhesive is distributed in multiple positions and separated. The amount of adhesive flowing out of different positions can be controlled according to the amount of pressure applied during bonding. The adhesive will not completely solidify after use, thus achieving the purpose of reusing the adhesive.
[0027] To improve the stability of the separator ball 21, refer to Figure 2 and Figure 3 The top of the substrate 1 is provided with an inlay groove 4 corresponding to the partition ball 21. The partition ball 21 is installed on the top of the inlay groove 4. The inlay groove 4 is composed of a plurality of neatly arranged basic grooves. The cross-section of the basic groove is either square or regular hexagonal.
[0028] In use, a stamping device is used to stamp the inlay groove 4 on the substrate 1. According to the required shape of the inlay groove 4, a square or regular hexagonal stamping head can be installed on the stamping device. The arrangement of the inlay grooves 4 increases the contact area between the separator ball 21 and the substrate 1 after it is pressed onto the substrate 1. The separator ball 21 and the substrate 1 are fixed together with adhesive. Due to the presence of the inlay groove 4 between the separator ball 21 and the substrate 1, the contact area is increased. Therefore, a larger area of adhesive can be attached between the separator ball 21 and the substrate 1, thereby improving the firmness of the connection between the separator ball 21 and the substrate 1 by using more adhesive.
[0029] To improve the sealing performance of adhesive patches and slow down the rate at which the adhesive layer absorbs moisture or dries during storage, refer to... Figure 1 A sealing frame 5 is fixedly connected to the top of the substrate 1. The composite adhesive layer 2 is installed inside the sealing frame 5. When in use, the sealing frame 5 wraps a part of the composite adhesive layer 2 to reduce the area of the composite adhesive layer 2 in contact with the outside air, thereby slowing down the rate at which the composite adhesive layer 2 of the adhesive patch absorbs moisture or dries out during storage.
[0030] To further achieve the goal of reusing the adhesive, refer to Figure 4 The separator sphere 21 includes an upper hemisphere 211 and a lower hemisphere 212. The interior of the upper hemisphere 211 is filled with pressure-sensitive adhesive, and the interior of the lower hemisphere 212 is filled with air. A plurality of protrusions 6 are fixedly connected to the top of the upper hemisphere 211, and one end of the protrusions 6 extends movably into the interior of the upper hemisphere 211.
[0031] In use, the pressure-sensitive adhesive filled inside the separator sphere 21 divides the adhesive in the adhesive patch into three parts: a lower adhesive layer 22, an upper adhesive layer 23, and a pressure-sensitive adhesive. This allows the upper adhesive layer 23 and the lower adhesive layer 22 to be used separately by applying different pressures. Furthermore, the pressure-sensitive adhesive can be further pressed to trigger adhesion, reducing residue during peeling and supporting multiple uses. The bump 6 facilitates faster cracking of the upper hemisphere 211 during pressing, resulting in a faster response speed for the pressure-sensitive adhesive inside the upper hemisphere 211 during use.
