Examples

As shown in fig. 1 and fig. 2, a schematic diagram of a frame-attached single-sided adhesive sponge structure according to this embodiment is provided, where the structure includes:

the frame-pasted single-sided adhesive sponge body 2 comprises four frame edges which are oppositely arranged, and the four frame edges which are oppositely arranged form a hollow area;

the front release film 1 is a complete one-sided film, the whole surface of the front release film is covered on the front surface of the frame-attached single-sided adhesive sponge body 2, no hollowing is needed, and a tearing hand 11 is arranged at one corner of the film; the front release film 1 is a heavy release film.

The back release film 3 is arranged on the back of the frame-attached single-sided adhesive sponge body 2; also, the film is not hollowed out and covered completely. The back release film 3 is a light release film.

Because the single-sided sticky sponge is punched, in order to cut out the single-sided sticky sponge meeting the size requirement, the junction of the heavy release film tearing hand 11 and the single-sided sticky sponge generally has a shear mark 12, and the single-sided sticky sponge is punched out to be used for delivering a client, and needs to be assembled by a touch screen factory and a module factory, and the colloid at the junction is easy to permeate into the shear mark 12 at the junction of the heavy film, so that when the client tears off the heavy release film, the colloid is easy to be layered with the sponge body due to the fact that the colloid is already stuck together with the heavy film.

As shown in fig. 1, a separation film 4 is arranged between the tearing hand 11 and the downward extending part of the front release film 1 and the frame-attached single-sided adhesive sponge body 2. The separating film 4 is arranged from the tearing hand 11 and extends downwards to the position between the front release film 1 and the frame-attached single-sided adhesive sponge body 2, and the separating film 4 of the part is triangular in shape and is arranged at the corners.

Preferably, the release force of the separation membrane 4 is 0.1N/25mm and the thickness is 25um. The release force of the separation membrane 4 is very low, and the separation is easy when in use.

According to the utility model, when a die-cutting manufacturer produces single-sided sticky sponge, the next post directly attaches the separating film 4 at the junction of the tearing hand 11 of the front release film 1 and the frame-attached single-sided sticky sponge body 2, and the release force of the separating film 4 is very low, so that the problem that colloid generated by long-term placement of a product permeates into the cutting marks 12 of the front release film 1 can be solved, and the problem of poor layering when the front release film 1 is naturally torn off at a client side is also solved.

Preferably, the single-sided adhesive sponge comprises a colloid and a sponge body, wherein the thickness of the sponge body is 0.3-1.0m. The initial viscosity of the gel was 30N/24mm.

Preferably, the front release film 1 is a heavy release film with a thickness of 75um and a release force of 0.4N/25mm. The front release film 1 is torn off from the client.

Preferably, the back release film 3 is a light release film having a thickness of 50um,0.1N/25mm.

Preferably, in order to just protect the frame-attached single-sided adhesive sponge body 2, the shapes of the front release film 1 and the back release film 3 are larger than the shape of the frame-attached single-sided adhesive sponge body 2.
