Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a top view of a structure of an adhesive according to an embodiment of the present disclosure.
The adhesive 10 comprises a release film 101 and a back adhesive 102; the release film 101 covers and adheres to the back adhesive 102, a first notch 1011 perpendicular to a first designated edge is arranged on the release film 101 along the first designated edge of the release film 101, the first notch 1011 takes the first designated edge as a starting end and takes a first preset distance from the first designated edge as a tail end, the first preset distance is smaller than the length of the adjacent edge of the first designated edge, and a hole-shaped structure 1012 is arranged at the tail end.
Optionally, the first preset distance may be flexibly adjusted according to a specific size of the release film 101, and may be, but is not limited to, 3 cm, 5 cm, or 10 cm.
In order to increase the release force of the release film 101, the release film 101 is plasma-treated, fluorine-coated or silicon-coated on the surface of the release film 101, so that the release film 101 can exhibit very light and stable release force for different organic pressure-sensitive adhesives (such as hot-melt adhesive, acrylic and rubber-based pressure-sensitive adhesives).
The gum 102 may be vegetable gum (such as corn gum, acacia gum), animal gum (such as hide glue, bone glue), chemical gum (such as polyvinyl alcohol gum).
It can be understood that the release film 101 needs to be peeled off after the adhesive 102 is attached to the surface of the product, and the adhesive 102 remains on the surface of the product, but in the actual production process, because of the weak adhesion between the release film 101 and the adhesive 102, there is a phenomenon that the adhesive 102 is simultaneously taken up when the release film 101 is peeled off. Set up first incision 1011, can guarantee to peel off this from type membrane 101 in-process first incision 1011 one side from type membrane 101 atress and gum 102 and peel off, first incision 1011 opposite side is from type membrane 101 not atress and keep with gum 102's laminating state for gum 102 does not receive the atress, takes up the phenomenon of gum 102 when avoiding peeling off this from type membrane 101 in order to appear.
The hole-shaped structure 1012 is arranged at the tail end of the first cut 1011, so that the stress of the release film around the hole-shaped structure 1012 is uniform in the process of peeling the release film 101, the release film is prevented from being torn in the process of peeling the release film 101, and the yield of adhesive can be improved. As an example, the hole-like structure 1012 may be circular, triangular, oval, or other common geometric shapes.
Optionally, a second notch perpendicular to the second designated edge is disposed on the release film 101 along the second designated edge of the release film 101, the second notch uses the second designated edge as a starting end, and uses a second predetermined distance from the second designated edge as a tail end, and the second designated edge is any edge outside the first designated edge.
It can be understood that the first notch 1011 and the second notch are formed on the release film 101 at the same time, which facilitates the user to peel the release film 101 from the adhesive 102 from a plurality of angles, and improves the convenience of the adhesive 10.
Optionally, the release film 101 is provided with a peeling portion 1015 extending along the first cut 1011 to a specified length outside the release film 101 at a portion on either side of the first cut 1011.

The release film 101 can be peeled off from the back adhesive 102 with the peeling portion 1015 as a stress point, and the convenience of use of the adhesive 10 is improved.
Optionally, both sides of the peeling part 1015 are provided with a frosted texture.
Sanding is a process of making an object with a smooth surface unsmooth and irradiating light on the surface to form a diffuse reflection shape. The frosting treatment is to mechanically or manually grind the glass by using abrasives such as carborundum, silica sand, pomegranate powder and the like, and to make the peeling part 1015 into a uniform and rough surface by using fine powder such as the carborundum, the silica sand, the pomegranate powder and the like.
The frosted texture can improve the friction between the hand and the release film 101 when peeling off the release film 101, so that the user can peel off the back adhesive 102 from the release film 101, and the use convenience of the adhesive 10 is improved.
Referring to fig. 2, fig. 2 is a schematic view of a second adhesive according to an embodiment of the present disclosure. Optionally, the release film 101 includes a first release film 1013 and a second release film 1014, and the first release film 1013 and the second release film 1014 respectively cover and are attached to two sides of the back adhesive 102.
When the first release film 1013 and the second release film 1014 are peeled off the back adhesive 102, the back adhesive 102 can bond two different things, and the applicability of the adhesive 10 is improved.
Referring to fig. 3, fig. 3 is a schematic view of a third adhesive according to an embodiment of the present disclosure. Optionally, either end of the release film 101 is provided with a release sheet 103, and the release sheet 103 is used for peeling off the release film 101 and the back adhesive 102.
The release sheet 103 is arranged at any end of the release film 101 and can be adhered to the release film 101, the release sheet 103 is used as a stress point to peel the back adhesive 102 from the release film 101, and the use convenience of the adhesive 102 is improved.
Alternatively, the release film 101 and the back adhesive 102 are the same shape.
The shape of the release film 101 and the shape of the back adhesive 102 are the same, so that the release film 101 covers the back adhesive 102, and meanwhile, the area of the release film 101 is prevented from being larger than that of the back adhesive 102, so that raw materials of the release film 101 are saved.
Referring to fig. 4, fig. 4 is a schematic view of a release film according to an embodiment of the present application. Optionally, an embodiment of the present application provides a release film 101, where a first notch 1011 perpendicular to a first designated edge is disposed along the first designated edge of the release film 101, the first notch 1011 takes the first designated edge as a starting end and takes a first preset distance from the first designated edge as an ending end, the first preset distance is smaller than a length of an adjacent edge of the first designated edge, and a hole-shaped structure 1012 is disposed at the ending end.
