Description

Technical Field

[0001] The utility model relates to the field of double-sided adhesive tapes, in particular to a high-viscosity barrier plasticized double-sided mesh adhesive tape. Background Art

[0002] Double-sided tapes are widely used in the market. High-end double-sided tapes can effectively ensure the fit of door and window sealing strips, foam and automotive movable parts, play a role of two-way reinforcement and firmness, and have extremely strong wear resistance, impact resistance and high holding power.

[0003] With the continuous updating of materials such as door and window sealing strips, foams, plastic strips, etc., in order to improve the plasticity and flexibility of materials such as door and window sealing strips, foams, plastic strips, etc., a material called "plasticizer" will be added to the common door and window sealing strips, foams, plastic strips and other adhered materials on the market. However, plasticizers will cause a series of adverse reactions such as glue overflow, glue seepage, and glue flow on the double-sided tape on the adhered object, thereby affecting the bonding strength and adhesion time of the double-sided tape. Summary of the invention

[0004] In view of the deficiencies of the above background technology, the utility model provides a high-viscosity barrier plasticized double-sided mesh tape.

[0005] The utility model adopts the following technical solutions:

[0006] A high-viscosity barrier plasticized double-sided mesh tape, the tape comprising a reel and a tape body wound around the outside of the reel, characterized in that the tape body comprises:

[0007] An adhesive layer, wherein a mesh cloth is laid flat in the middle of the adhesive layer and the adhesive layer is wrapped around the outside of the mesh cloth;

[0008] A base layer, wherein the base layer is formed by splicing a plurality of base layer blocks, and the base layer blocks are hollow inside to form a cavity, and the cavity is filled with primer liquid;

[0009] A film layer, wherein the film layer is made of a non-stick material;

[0010] Wherein, both the upper and lower surfaces of the base layer are covered with a film layer, the outer surface of the film layer is flat and smooth, and the outer surface of the film layer located on the lower surface of the base layer is covered with the adhesive layer.

[0011] As a further improvement, the widths of the adhesive layer, the base layer and the film layer are equal.

[0012] As a further improvement, the mesh is made of glass fiber.

[0013] As a further improvement, the base layer is integrally formed.

[0014] As a further improvement, marking areas are provided on the surfaces of both ends of the base block, and the film layer is made of a transparent material.

[0015] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: when in use, the tape is torn off or cut off along the junction of adjacent base blocks, and then the base is broken, and the primer liquid flowing out of the base is evenly applied to the position to be pasted on the object to be pasted. After the primer liquid hardens on the surface of the object to be pasted to form a thin film, the adhesive layer is torn off from the base layer and pasted on the thin film formed by the hardening of the primer liquid. The primer liquid is used to assist the adhesive layer, so that the adhesive layer can be smoothly pasted on the object to be pasted, while blocking the adhesive layer and the object to be pasted, blocking the penetration of the plasticizer, preventing the plasticizer on the object to be pasted from transferring to the adhesive layer, avoiding a series of adverse reactions such as overflow, seepage, and flow of the adhesive layer, thereby ensuring the adhesive strength and adhesion time of the tape. At the same time, the mesh cloth is set to give the adhesive layer better tensile strength and is not easy to break. The utility model adopts a high-weight adhesive amount and high-performance materials to make the tape have a better feel and viscosity. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0022] As attached Figure 1 and Figure 2 As shown, a high-viscosity barrier plasticized double-sided mesh tape includes a reel 1 and a tape body 2 wound around the outside of the reel 1, wherein the tape body 2 includes an adhesive layer 21, a base layer 22 and a film layer 23, and the widths of the adhesive layer 21, the base layer 22 and the film layer 23 are equal, so that after the tape body 2 is wound around the outside of the reel 1, the side surface can be smooth and beautiful.

[0023] As attached Figure 2 and Figure 5As shown, both the upper and lower surfaces of the base layer 22 are covered with a film layer 23, the outer surface of the film layer 23 is flat and smooth, and the outer surface of the film layer 23 located on the lower surface of the base layer 22 is covered with a glue layer 21, wherein the base layer 22 can be made of paper, cloth or plastic film, as the main support of the tape, the film layer 23 is a non-stick material, specifically, silicone is coated on the surface of the base layer 22 to form a film layer 23 called a silicone oil layer, thereby achieving a non-stick and oil-proof effect, and the glue layer 21 is formed by coating transparent glue on the film layer 23, and the transparent glue is usually an acrylic emulsion, which has strong adsorption and adhesion capabilities and is a key part to achieve the bonding effect. At the same time, since the outer surface of the film layer 23 is flat and smooth, the adhesive layer 21 and the film layer 23 can fit evenly. After the tape body 2 is wound around the outside of the reel 1, the film layer 23 can protect the adhesive layer 21. On the one hand, it prevents the adhesive layer 21 from contacting and adhering to the surrounding environment. On the other hand, it isolates the base layer 22 from the adhesive layer 21, so that the adhesive layer 21 can be smoothly torn off from the base layer 22 when in use, exposing the adhesive layer 21 to exert its adhesive effect.

[0024] It is worth mentioning that Figures 2 to 4 As shown, the base layer 22 is formed by splicing a plurality of base layer blocks 221, and the base layer blocks 221 are hollow inside to form a cavity, and the cavity is filled with primer liquid 222, wherein the base layer 22 is integrally formed, specifically, a flat paper, cloth or plastic film is folded in half, and the primer liquid 222 is sealed in the folded paper, cloth or plastic film by a hot pressing process to form the base layer 22. When in use, the adhesive tape can be torn off or cut off along the junction of adjacent base blocks 221. When the adhesive layer 21 is pasted on the surface of the adhered object such as door and window sealing strips, foam, plastic strips, etc., the base layer 22 is first broken, and the primer liquid 222 flowing out of the base layer 22 is evenly applied to the to-be-adhered position of the adhered object. After the primer liquid 222 hardens to form a thin film on the surface of the adhered object, the adhesive layer 21 is torn off from the base layer 22 and pasted on the thin film formed by the hardening of the primer liquid 222. The primer liquid 222 is used to assist the adhesive layer 21, so that the adhesive layer 21 can be smoothly adhered to the adhered object, while blocking the adhesive layer 21 and the adhered object, blocking the penetration of the plasticizer, preventing the plasticizer on the adhered object from being transferred to the adhesive layer 21, and avoiding a series of adverse reactions such as overflow, seepage, and flow of the adhesive layer 21, thereby ensuring the bonding strength and adhesion time of the adhesive tape.

[0025] In addition, if attached Figure 4 The surfaces of both ends of the base block 221 are provided with identification areas 223, which are different in color from the base block 221, and the film layer 23 made of silicone is transparent, ensuring that the user can clearly see the identification area 223. The setting of the identification area 223 can facilitate the user to accurately tear off or cut the tape to avoid leakage of the primer liquid 222.

[0026] In addition, as attached Figure 5As shown, a mesh cloth 211 is laid flat in the middle of the adhesive layer 21, and the adhesive layer 21 is wrapped around the outside of the mesh cloth 211, wherein the mesh cloth 211 is made of glass fiber, specifically woven with glass fiber yarns. Glass fiber has the characteristics of high temperature resistance, non-flammability, corrosion resistance, good heat insulation and sound insulation, high tensile strength, good electrical insulation, etc. The mesh cloth 211 made of glass fiber material allows the adhesive layer 21 to have better tensile strength and is not easy to break.

[0027] In summary, when the utility model is used, the adhesive tape is torn off or cut off along the junction of the adjacent base blocks 221, and then the base 22 is broken, and the primer liquid 222 flowing out of the base 22 is evenly applied to the position to be pasted on the object to be pasted, and after the primer liquid 222 hardens to form a thin film on the surface of the object to be pasted, the adhesive layer 21 is torn off from the base 22 and pasted on the thin film formed by the hardening of the primer liquid 222. The primer liquid 222 is used to assist the adhesive layer 21, so that the adhesive layer 21 can be smoothly pasted on the object to be pasted, while blocking the adhesive layer 21 and the object to be pasted, blocking the penetration of the plasticizer, preventing the plasticizer on the object to be pasted from being transferred to the adhesive layer 21, and avoiding a series of adverse reactions such as overflow, seepage, and flow of the adhesive layer 21, thereby ensuring the adhesive strength and adhesion time of the tape. At the same time, the mesh 211 is provided to give the adhesive layer 21 better tensile strength and is not easy to break. The utility model adopts high-weight glue and high-performance materials, so that the adhesive tape has better feel and viscosity.

[0028] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
