Description

Technical Field

[0001] The utility model relates to the technical field of double-sided adhesive tapes, in particular to a double-sided adhesive tape which is convenient for peeling off a release layer. Background Art

[0002] As a widely used adhesive material, the performance and ease of use of double-sided adhesive tape have always been the focus of research and improvement. During the use of double-sided adhesive tape, the peeling efficiency and effect of the release layer directly affect the integrity and use experience of the double-sided adhesive tape. Therefore, it is particularly important to develop a double-sided adhesive tape that is easy to peel off the release layer.

[0003] After using traditional double-sided tape, the PET base layer will age over time and adhere to the surface of the object under the action of the acrylic adhesive layer. It is easy to break when cleaning. If it is not cleaned thoroughly, the residue on the surface of the object will easily absorb dust, affecting the appearance and making it less suitable for use. Utility Model Content

[0004] The utility model aims to provide a double-sided adhesive tape with a release layer that is easy to peel off, so as to solve the defect that the acrylic adhesive layer of the existing double-sided adhesive tape is inconvenient to clean.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a double-sided adhesive tape that facilitates peeling of a release layer, comprising a double-sided adhesive tape body;

[0006] The double-sided adhesive body comprises a PET substrate layer, an acrylic adhesive layer and a fiber mesh, wherein both sides of the PET substrate layer are provided with an acrylic adhesive layer, and a fiber mesh is provided on the side of the acrylic adhesive layer away from the PET substrate layer;

[0007] The interior of the PET substrate layer is uniformly penetrated with reserved grooves;

[0008] The reserved slots include a first empty slot and a second empty slot that are adjacently distributed.

[0009] Preferably, a release film is provided on one side of the PET substrate layer.

[0010] Preferably, the inner side wall of the release film contacts one side of the outer fiber web of the PET substrate layer, and the outer side wall of the release film contacts one side of the inner fiber web of the PET substrate layer.

[0011] Preferably, release films are provided on both sides of the PET substrate layer.

[0012] Preferably, a side of the release film close to the PET substrate layer is in contact with a side of the fiber web away from the PET substrate layer.

[0013] Preferably, a peeling sheet is evenly fixed to the bottom end of the release film.

[0014] Preferably, the contact surfaces of the first and second empty grooves and the contact lines between adjacent stripping sheets are located in the same vertical plane.

[0015] The utility model provides a double-sided adhesive tape that is easy to peel off the release layer, and its advantages are:

[0016] By providing a fiber net, the fiber net is bonded to both sides of the PET substrate layer through the acrylic adhesive layer. During use, the fiber net is located on both sides of the PET substrate layer. Under the action of the fiber net, when cleaning the PET substrate layer, it is only necessary to pull the fiber net at one end of the PET substrate layer. The fiber net will drive the acrylic adhesive layer and the PET substrate layer to separate from the object, thereby realizing the function of facilitating the cleaning of the double-sided adhesive tape, thereby improving the applicability of the double-sided adhesive tape during use.

[0017] By providing a peeling sheet, the release film can be easily peeled off from one side of the fiber web under the action of the peeling sheet, thereby avoiding the release film from being torn and left over during the peeling process, which affects the adhesion between the acrylic adhesive layer and the surface of the object, thereby improving the convenience of the double-sided adhesive when in use;

[0018] By providing a reserved groove, the contact surface of the first empty groove and the second empty groove and the contact line between adjacent peeling sheets are located in the same vertical plane. When the double-sided adhesive tape body needs to be torn off, it can be torn through the contact line between the adjacent peeling sheets to separate the first empty groove and the second empty groove from each other, thereby keeping the fracture surface flat, thereby improving the neatness of the double-sided adhesive tape when in use.
