Description

Technical Field

[0001] This utility model relates to the field of masking tape technology, specifically a high-toughness masking tape. Background Technology

[0002] Masking tape is made primarily of masking paper and pressure-sensitive adhesive. It features excellent pressure-sensitive solvent coating, high adhesion, softness, and leaves no residue after removal. Masking tape can be categorized into three types based on temperature: room temperature masking tape, medium temperature masking tape, and high temperature masking tape.

[0003] For example, a high-toughness masking tape with publication number CN219824067U relates to the field of masking tape technology. It addresses the problem that existing masking tapes allow solvent to flow from the inside of the wrapping layer to the surface of the bonded object for adhesion, but the solution inside the tape will solidify if not used for a long time, and the built-in solution will affect the overall structural strength of the tape. The device includes a tape reel with masking tape wound around its outer wall, and a tear-off opening between adjacent masking tape sections; it also includes an adhesive layer integrally formed with the masking tape, located on the inner wall of the masking tape; and a textured layer integrally formed with the masking tape on its outer wall; and two through-holes integrally formed with the masking tape, each with a plastic strip inside.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that while the device increases the toughness of the masking tape by filling it with plastic tape, the addition of the plastic tape limits the tape's softness and elasticity, reducing its conformability. When pasting on curved or uneven surfaces, it is difficult to achieve a complete fit, easily causing air bubbles and wrinkles, thus affecting the performance. Furthermore, masking tape typically requires a certain degree of weather resistance, and the filled plastic tape may not match the weather resistance of the masking paper or adhesive. Under different environmental conditions such as temperature and humidity, the plastic tape and the masking paper / adhesive may have inconsistent expansion coefficients, leading to problems such as tape deformation and cracking, thus shortening its service life.

[0005] Therefore, a high-toughness masking tape is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and the problem of poor conformability, this utility model proposes a high-toughness masking tape.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a high-toughness masking tape, including a roll, the surface of which is wound with masking tape, the masking tape including a substrate, a scissor-type fixing strap fixedly installed in the middle of the working surface of the substrate, a plurality of groups of acrylic pressure-sensitive adhesives provided on the working surface of the substrate, a double-sided adhesive layer fixedly installed on the outer side of the acrylic pressure-sensitive adhesives, and a release film fixedly installed on the back of the substrate.

[0008] Preferably, the scissor-type fixing strap is fixedly connected to the substrate by adhesive, and the scissor-type fixing strap is deployed in a middle supporting manner at the top of the substrate.

[0009] Preferably, the acrylic pressure-sensitive adhesive is fixedly connected to the substrate by an adhesive, and the acrylic pressure-sensitive adhesive is located on top of the substrate and fills the blank space of the scissor-type fixing strip.

[0010] Preferably, the double-sided adhesive layer is bonded to an acrylic pressure-sensitive adhesive.

[0011] Preferably, the release film is fixedly connected to the substrate by adhesive.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model, through the structural design of a substrate, scissor-type fixing tape, acrylic pressure-sensitive adhesive, double-sided adhesive layer, and release film, and through the mutual cooperation of the components, achieves the function of increasing the toughness of masking tape. This can disperse external force, reduce local stress concentration in the masking tape, thereby improving the overall tensile strength and tear resistance of the masking tape. At the same time, it avoids the drawback of reduced flexibility caused by traditional fully filled plastic tape and solves the problem of poor conformability.

[0014] 2. By symmetrically deploying the scissor-type fixing tape in the middle, this utility model can ensure that the masking tape can be subjected to force evenly when subjected to external interference, and can also make the masking tape still fit various complex surface shapes and maintain good operation performance.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a high-toughness masking tape, including a roll 1, with masking tape 2 wound around the surface of the roll 1. The masking tape 2 includes a substrate 201, with a scissor-type fixing strap 202 fixedly installed in the middle of the working surface of the substrate 201. The working surface of the substrate 201 is provided with a plurality of acrylic pressure-sensitive adhesives 203. A double-sided adhesive layer 204 is fixedly installed on the outer side of the acrylic pressure-sensitive adhesives 203. A release film 205 is fixedly installed on the back side of the substrate 201.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Through the structural design of the substrate 201, scissor-type fixing tape 202, acrylic pressure-sensitive adhesive 203, double-sided adhesive layer 204, and release film 205, and through the mutual cooperation between the components, the function of increasing the toughness of the masking tape is achieved. This can disperse external forces, reduce local stress concentration in the masking tape, thereby improving the overall tensile strength and tear resistance of the masking tape, while avoiding the drawback of reduced flexibility caused by traditional fully filled plastic tape.

[0025] The scissor-type fixing strap 202 is fixedly connected to the substrate 201 by adhesive, and the scissor-type fixing strap 202 is located on the top of the substrate 201 and is deployed in a middle supporting manner.

[0026] Reference Figure 2 and Figure 4 The symmetrical deployment of the scissor-type fixing tape 202 in the middle ensures that the masking tape can be evenly stressed when subjected to external force interference, and also allows the masking tape to still conform to various complex surface shapes and maintain good operational performance.

[0027] The acrylic pressure-sensitive adhesive 203 is fixedly connected to the substrate 201 by adhesive. The acrylic pressure-sensitive adhesive 203 is located on top of the substrate 201 and fills the blank space of the scissor-type fixing strip 202.

[0028] Reference Figure 3 and Figure 4 The acrylic pressure-sensitive adhesive 203 facilitates filling the blank spaces at the edges of the scissor-type fixing strip 202 in the substrate 201 and the double-sided adhesive layer 204, thereby ensuring the connection strength between the substrate 201 and the double-sided adhesive layer 204.

[0029] Double-sided adhesive layer 204 is bonded to acrylic pressure-sensitive adhesive 203.

[0030] Reference Figure 3 and Figure 4 The double-sided adhesive layer 204 and the acrylic pressure-sensitive adhesive 203 are bonded together to ensure the overall strength and toughness of the masking tape, thus ensuring that the masking tape is suitable for different scenarios.

[0031] The release film 205 is fixedly connected to the substrate 201 by adhesive.

[0032] Reference Figure 2 and Figure 4 The release film 205 is bonded to the substrate 201, which facilitates the application to the back of the substrate 201, thereby avoiding mutual interference between adjacent masking tapes and ensuring the bonding strength of the adhesive on the masking tape.

[0033] Working principle: When using this device, the scissor-type fixing tape 202 ensures that the masking tape 2 is evenly stressed during the stretching process. The acrylic pressure-sensitive adhesive 203 fills the hollow parts of the substrate 201 and the double-sided adhesive layer 204 to ensure the connection strength between the substrate 201 and the double-sided adhesive layer 204 and the tensile strength of the overall masking tape 2. The back of the double-sided adhesive layer 204 is used to bond the acrylic pressure-sensitive adhesive 203 and the scissor-type fixing tape 202. The front of the double-sided adhesive layer 204 is used to adhere the working bonding area. The release film 205 ensures that the adjacent masking tapes 2 wound on the surface of the roll 1 are bonded to each other.
