Description

Technical Field

[0001] This utility model relates to the field of release paper technology, specifically to a release paper suitable for mesh fabric-based adhesive tape. Background Technology

[0002] Adhesive products are widely used in modern industrial production and daily life. Among them, mesh cloth tape plays an important role in many fields due to its unique performance advantages.

[0003] Mesh-based adhesive tape typically consists of a substrate, adhesive, and release paper (film). The substrate is usually made of fiber fabric or cloth, which gives the tape good strength and flexibility, allowing it to withstand a certain degree of tension and tearing without easily breaking, thus ensuring stability and reliability during use. The adhesive is mostly made of natural or synthetic rubber, providing a high-viscosity bonding effect, ensuring a tight adhesion between the tape and the object's surface, meeting the bonding needs of different scenarios. The release paper (film) covers the surface of the tape, protecting the adhesive before use and easily peeling off during application, providing convenience for the user.

[0004] However, existing mesh-based adhesive tapes still have some problems in practical applications. In the bonding process between the release liner and the tape, they often adhere too tightly. This makes it difficult to separate the release liner and tape during use, increasing the difficulty for users and consuming more time and effort. Furthermore, forcibly separating them can easily damage the tape or release liner, affecting the tape's normal use. Residual release liner may even contaminate the adhesive surface of the tape, reducing its tack and thus affecting subsequent bonding results.

[0005] Furthermore, in certain specialized applications, such as production lines requiring high bonding efficiency, or in harsh outdoor environments, the difficulty in separating the release liner from the tape becomes particularly prominent, severely limiting the application range and effectiveness of mesh fabric tapes. Therefore, solving the problem of excessively tight adhesion and difficulty in separating the release liner from the tape has become a critical technical challenge urgently needing to be addressed in the current field of mesh fabric tapes. Summary of the Invention

[0006] In view of the problems pointed out in the background art, this utility model proposes a release paper suitable for mesh cloth-based adhesive tape to solve the above-mentioned technical problems.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A release paper suitable for mesh fabric-based adhesive tape includes a first paper layer, wherein a plurality of through holes are distributed on the first paper layer, and a first release agent layer is provided on the inner side surface of the first paper layer.

[0009] The present invention is further configured such that a second paper layer is provided on the outer surface of the first paper layer.

[0011] The present invention is further configured such that a second release agent layer is provided on the outer surface of the third paper layer.

[0012] The present invention is further configured such that a coating layer is provided between the first release agent layer and the first paper layer.

[0013] The present invention is further configured such that a coating layer is provided between the second release agent layer and the third paper layer.

[0014] The present invention is further configured such that the first paper layer, the second paper layer, and the third paper layer are fixedly bonded together by adhesive.

[0016] The present invention is further configured such that the through hole one and the through hole two are provided correspondingly.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0018] The release paper for mesh fabric-based adhesive tape provided by this utility model provides users with clear gripping points by setting a through hole one on the first paper layer and a through hole two on the third paper layer, making it easy to tear from either side of the release paper.

[0025] 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.

[0026] For reference as follows Figures 1-4 The present invention will be described as follows:

[0027] Example: A release paper suitable for mesh fabric-based adhesive tape includes a first paper layer 1 with a plurality of through holes 2 distributed on the first paper layer 1. These through holes 2 have a specific functional purpose. When the release paper needs to be torn off, they transform into highly practical notch structures. In actual operation, when the user's hand contacts the release paper and wants to initiate the tearing action, the notches formed by these through holes 2 act as "force points," allowing the fingers to precisely embed into them, thus providing an initial point of force for tearing the release paper. This makes the tearing action smooth, overcoming the previous difficulty of not being able to start due to the smooth surface of the release paper.

[0028] A first release agent layer 3 is provided on the inner side of the first paper layer 1 (that is, the side that is in direct contact with the adhesive of the mesh cloth tape). The key function of the first release agent layer 3 is to adjust the degree of adhesion between the release paper and the tape.

[0029] A second paper layer 4 is provided on the outer surface of the first paper layer 1. The second paper layer 4 further enhances the overall structural stability of the release paper. On the one hand, it provides intermediate transition support for the subsequent construction of multi-layer structures, making the bonding between layers tighter; on the other hand, from a functional perspective, it can, to a certain extent, assist in adjusting the physical properties of the release paper, such as flexibility and stiffness, so that it can better adapt to different usage environments and tape characteristic requirements.

[0030] A third paper layer 5 is provided on the outer surface of the second paper layer 4, and several through holes 6 are distributed on the third paper layer 5. These through holes 6 serve the same purpose as the through holes 2 on the first paper layer 1, also for the tearing operation. When tearing from the other side of the release paper, the through holes 6 become the key starting point of force, allowing the user to easily insert their fingers to initiate the tearing process, greatly improving the convenience of operation.

[0031] A second release agent layer 7 is provided on the outer surface of the third paper layer 5. The existence of this release agent layer is of great significance. It works with the first release agent layer 3 to achieve the breakthrough of release paper having release function on both sides. In practical applications, whether the front or back of the mesh cloth tape is in contact, the corresponding release agent layer can just right balance the adhesion relationship with the tape.

[0032] A coating layer 8 is provided between the first release agent layer 3 and the first paper layer 1.

[0033] A coating layer 8 is provided between the second release agent layer 7 and the third paper layer 5. The coating layer 8 provides additional moisture-proof and waterproof protection for the first paper layer 1 and the third paper layer 5, preventing external moisture from intruding and affecting the overall performance of the release paper. Especially in some high-humidity environments, it can effectively maintain the dry state of the release paper and ensure that it can perform its normal release function.

[0034] The first paper layer 1, the second paper layer 4, and the third paper layer 5 are bonded together with adhesive. The use of adhesive achieves a tight bond between the multiple paper layers, creating a stable overall structure.

[0035] The second paper layer 4 has ventilation holes 9 or ventilation slots for connecting through holes 2 and 6. Through holes 2 and 6 are correspondingly arranged. Firstly, because through holes 2 and 6 are correspondingly arranged, they play a crucial role in providing the starting point of force for the tearing operation on both sides of the release paper. The addition of ventilation holes 9 or ventilation slots further enhances this ease of tearing. When the user starts tearing the release paper from either side, air can flow smoothly through these connecting channels. On the one hand, the airflow effectively balances the air pressure difference generated on both sides of the release paper due to the tearing action, preventing uneven air pressure from causing the release paper to adhere tightly to the tape in some areas, resulting in tearing difficulties. For example, during rapid tearing, without a ventilation structure, a local vacuum area may form between the release paper and the tape, causing the release paper to re-adhere to the tape, hindering the tearing process; however, with ventilation holes 9 or ventilation slots, air rushes in in time, maintaining air pressure balance and ensuring smooth tearing.

[0036] On the other hand, the vent holes 9 or vent slits also help improve the overall air permeability of the release paper. In some applications where air permeability is critical, such as when tape is used to bond materials with poor air permeability, or when tape is used in high-temperature and high-humidity environments, the good air permeability of the release paper can prevent moisture from accumulating between the tape and the release paper, preventing problems such as tape becoming damp and losing its adhesion. Furthermore, from a manufacturing process perspective, the location and size of the vent holes 9 or vent slits need to be precisely controlled. They must ensure effective communication with through holes 1 and 2 to achieve the aforementioned functions, while also not affecting the overall structural strength of the second paper layer 4, ensuring the stability of the release paper during processing, transportation, and use. This undoubtedly places higher demands on the release paper manufacturing process and highlights the meticulous considerations made by this design to meet diverse application needs.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
