Abstract
Description
Technical Field
[0001] This utility model relates to the field of release paper technology, and in particular to a fiber-reinforced high-strength tear-resistant release paper. Background Technology
[0002] Release paper, also known as silicone paper or anti-stick paper, primarily serves to separate sticky substances, such as adhesive tape. Release paper is generally peeled off and discarded during use. It is widely used in the food, pharmaceutical, and cosmetics packaging industries to package sticky products such as chewing gum, plasters, and self-adhesive labels, preventing them from sticking together during storage and transportation.
[0003] However, in existing technologies, tearing the release paper during label application or pulling it forcefully when opening the packaging can cause the release paper to tear, making it impossible to completely separate the release paper from the adhesive material. In some cases, some release paper may even remain on the surface of the adhesive material, affecting the performance. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the prior art that the release paper cannot be completely separated from the adhesive material, and some release paper may even remain on the surface of the adhesive material, affecting the performance. Therefore, a fiber-reinforced high-strength tear-resistant release paper is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fiber-reinforced high-strength tear-resistant release paper, comprising a release paper body, an anti-slip layer provided at the upper end of the release paper body, the release paper body comprising a fiber base layer, a reinforcing layer, a surface treatment layer and an anti-stick coating, the upper end of the anti-stick coating being fixed to the lower end of the surface treatment layer, the upper end of the surface treatment layer being fixed to the lower end of the reinforcing layer, and the upper end of the reinforcing layer being fixed to the lower end of the fiber base layer.
[0006] Preferably, the anti-slip layer comprises a nylon fiber layer and a nitrile rubber layer, wherein alumina particles are uniformly distributed on the surface of the nitrile rubber layer.
[0007] Preferably, a thermoplastic elastic layer is fixedly installed at the upper end of the nylon fiber layer.
[0008] Preferably, the lower end of the nitrile rubber layer is fixed to the upper end of the thermoplastic elastic layer.
[0009] Preferably, the lower end of the nylon fiber layer is fixed to the upper end of the fiber base layer.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] 1. In this utility model, the fiber base layer, reinforcing layer, surface treatment layer, and anti-stick coating work together. The fiber base layer provides basic toughness and support, while the reinforcing layer further enhances physical properties such as strength and tear resistance. The combination of these two allows the release paper to withstand greater tensile, compressive, and frictional forces, making it less prone to damage during use. The anti-stick coating provides a good release effect, and the surface treatment layer makes the surface smoother and more even, facilitating uniform adhesion of the anti-stick coating and enhancing the consistency and stability of the release paper itself. At the same time, the surface treatment layer enhances protective properties such as moisture resistance, working together with the anti-stick coating to prevent external factors from affecting the fiber base layer and reinforcing layer, thus extending the service life of the release paper. In summary, this invention can prevent the release paper itself from tearing, completely separate the release paper itself from the adhesive material, and prevent the release paper itself from remaining on the surface of the adhesive material, thus not affecting the performance.
[0012] 2. In this utility model, by setting an anti-slip layer, the combination of nylon fiber layer, nitrile rubber layer, alumina particles and thermoplastic elastic layer can make one side of the release paper body anti-slip, preventing the hand from sliding on the surface of the release paper body and affecting the peeling of the release paper body from the release material.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0019] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a fiber-reinforced high-strength tear-resistant release paper, including a release paper body 1, an anti-slip layer 2 provided at the upper end of the release paper body 1, the release paper body 1 including a fiber base layer 11, a reinforcing layer 12, a surface treatment layer 13 and an anti-stick coating 14, the upper end of the anti-stick coating 14 is fixed to the lower end of the surface treatment layer 13, the upper end of the surface treatment layer 13 is fixed to the lower end of the reinforcing layer 12, and the upper end of the reinforcing layer 12 is fixed to the lower end of the fiber base layer 11.
[0020] The specific settings and functions of this embodiment are described in detail below. The release paper body 1, composed of fiber base layer 11, anti-stick coating 14, reinforcing layer 12, and surface treatment layer 13, provides basic toughness and support through the cooperation of each layer. The reinforcing layer 12 further enhances the physical properties such as strength and tear resistance. The combination of the two enables the release paper to withstand greater tensile, compressive, and frictional forces, making it less prone to damage during use. The anti-stick coating 14 provides a good release effect, and the surface treatment layer 13 makes the surface smoother and more even, which is conducive to the uniform adhesion of the anti-stick coating 14 and enhances the consistency and stability of the release paper body 1. At the same time, the surface treatment layer 13 enhances the protective properties such as moisture resistance, and together with the anti-stick coating 14, prevents external factors from affecting the fiber base layer 11 and the reinforcing layer 12, thus extending the service life of the release paper.
[0021] The fiber base layer 11 provides basic support and strength for the release paper body 1. It is formed by fiber materials through papermaking processes, such as natural fibers like wood pulp fiber and bamboo pulp fiber or synthetic fibers. It is the main body and carrier of the entire release paper body 1 structure.
[0022] The main function of the reinforcing layer 12 is to further enhance the strength and toughness of the release paper body 1 and improve its tear resistance, tensile strength and other properties. The reinforcing layer 12 can be formed by coating or impregnating some reinforcing materials on the surface of the fiber base layer 11, such as some resin materials, fiber reinforcing agents, etc., which can fill the gaps between fibers, make the fibers more tightly bonded, and thus improve the overall strength.
[0023] The purpose of the surface treatment layer 13 is to optimize the surface of the release paper body 1, providing a better adhesion base for the subsequent anti-stick coating 14, and also to improve the surface properties of the release paper, such as flatness and smoothness. The surface treatment layer 13 usually adopts some chemical treatment methods or physical treatment processes, such as sizing and calendering, to make the surface of the release paper more uniform and delicate, which is conducive to the uniform coating of the anti-stick coating 14 and the performance of good performance.
[0024] The anti-stick coating 14 is in direct contact with the surface of the object to be isolated and is the key layer for realizing the release function. The anti-stick coating 14 is generally composed of materials with low surface energy, such as silicone oil and fluorides, which can make the object to be isolated easily peeled off from the release paper body 1 when needed, while maintaining a good anti-stick effect during use and preventing the object to be isolated from sticking to the release paper body 1.
[0025] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, the anti-slip layer 2 includes a nylon fiber layer 21 and a nitrile rubber layer 23. Alumina particles 24 are uniformly spread on the surface of the nitrile rubber layer 23. A thermoplastic elastic layer 22 is fixedly installed on the upper end of the nylon fiber layer 21. The lower end of the nitrile rubber layer 23 is fixed to the upper end of the thermoplastic elastic layer 22. The lower end of the nylon fiber layer 21 is fixed to the upper end of the fiber base layer 11.
[0026] The overall effect of this embodiment is that, with the cooperation of the nylon fiber layer 21, the nitrile rubber layer 23, the alumina particles 24, and the thermoplastic elastic layer 22, one side of the release paper body 1 can produce an anti-slip effect, preventing the hand from sliding on the surface of the release paper body 1 and affecting the peeling of the release paper body 1 from the release agent.
[0027] Nylon fiber layer 21 has high tensile strength and tear resistance, and can withstand large external forces and friction, and is not easily damaged;
[0028] The thermoplastic elastic layer 22, the thermoplastic elastomer has excellent elasticity and can quickly return to its original shape after being subjected to pressure, so that the anti-slip layer 2 can adapt to different pressure changes and deformation conditions, always maintain good contact with the object surface, and ensure the stability of the anti-slip effect;
[0029] The nitrile rubber layer 23 can maintain the stability of its physical and chemical properties, such as elasticity and hardness, even in environments with long-term contact with oil, ensuring sealing and protection effects and extending the product's service life in oily environments.
[0030] Alumina particles 24, distributed on the surface of nitrile rubber layer 23, can increase the surface roughness and further improve the anti-slip performance. Even after long-term use and friction, they can still maintain sharp edges and continue to provide good anti-slip effect.
[0031] The usage and working principle of this device are as follows: First, the release paper body 1, composed of fiber base layer 11, anti-stick coating 14, reinforcing layer 12, and surface treatment layer 13, works together. The fiber base layer 11 provides basic toughness and support, while the reinforcing layer 12 further enhances physical properties such as strength and tear resistance. Together, these two layers enable the release paper to withstand greater tensile, compressive, and frictional forces, making it less prone to damage during use. The anti-stick coating 14 provides a good release effect, and the surface treatment layer 13 makes the surface smoother and more even, facilitating the uniform adhesion of the anti-stick coating 14 and enhancing the consistency and stability of the release paper body 1. At the same time, the surface treatment layer 13 enhances protective properties such as moisture resistance, working together with the anti-stick coating 14 to prevent external factors from affecting the fiber base layer 11 and the reinforcing layer 12, thus extending the service life of the release paper.
[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
