Description

Re-adhesive film

This creation is about a diaphragm structure, especially a diaphragm structure that can be reattached on a repeated basis.

In recent years, the conventionally reproducible film structure is mainly used for providing decorative patterns on various surfaces (such as wall, tile, glass, etc.) or connecting various hanging objects, regardless of the general purpose. For households or for various commercial purposes, in the past, various adhesives were used as a way of sticking. When the film structure needs to be adjusted or replaced, the residual adhesive is often left on the surface of the adhesive, resulting in cleaning and aesthetics. The problem is that many adhesive surfaces that can be repeatedly applied and do not cause residuals have been developed as products that are more convenient and easy to operate, such as general tapes, double-sided tapes, and easy-to-tear tapes produced by Meishi 3M. Inert glue, etc. However, as for the glue used in most tapes, there is no problem of re-adhesive use in use, and it is easy to leave residual glue on the surface of the adhesive, or once it has been pasted, Viscosity is greatly lost and cannot be restored and reused. In addition to causing cleaning and aesthetic problems, the suitable place for use is also quite limited.

For example, a prior art such as the repetitive adherent cloth disclosed in the Republic of China Announcement No. M411441, the structure is a combination of a cloth layer and an elastic resin layer. The cloth layer can be any kind of natural fiber or rayon fabric, and the elastic resin layer can be repeatedly applied to any position, and can be peeled off and changed at any time, and has beautiful appearance and decorative effect. However, since the fabric layer needs to be combined with the elastic resin adhesive layer by means of hot melt adhesive, acrylic glue or shellac, the two-layer structure is relatively difficult to combine, and the decorative pattern of the cloth is also different depending on the material of the cloth. Differences, there are considerable restrictions on the choice, so there is still room for further development and improvement for the structure of re-stickable objects.

A re-peelable adhesive material as described in Japanese Patent No. TW 201105765, the adhesive material comprising a substrate layer and at least two adhesive layers, wherein one side of the substrate layer and the adhesive layer There is an internal peeling interface, and the peeling strength of the internal peeling interface is different from the peeling strength between the adhesive layer and the adherend. Therefore, although the adhesive material has the characteristics of double-sided adhesion and repeated adhesion, since the peeling strength of the adhesive interface is different, if the adhered article is subjected to a load force (such as a hook), it is easy to fall off due to poor adhesion. Therefore, there is still room for further development and improvement for the double-sided repeated pasting structure.

In view of the above shortcomings, the creator feels that he has not perfected it, exhausted his mind and researched and overcome it, and based on his accumulated experience in the industry for many years, he developed a re-adhesive film with a simple design. This product can achieve stable adhesion and re-adhesive use.

The present invention will be described in detail with reference to the drawings and the elements of the present invention, but not limited thereto.

Please refer to the first figure. The first figure is an exploded view of the first embodiment of the re-adhesive adhesive film. As shown in FIG. 1 , the double-sided adhesive film 100 of the present invention is mainly composed of a substrate 10 . a first film layer 20 and a second film layer 30, wherein the material of the substrate 10 is polyethylene terephthalate (PET), a first surface 11 and the first film The layer 20 is bonded to the second surface 12 as a base surface, and the second film layer 30 is attached to the surface of the first film layer 20, wherein the material of the first film layer 20 is a styrene elastic film layer. (SEBS), in the process of preparing the first film layer 20, the glass is exchanged at a temperature of 120-250 ° C through a high-temperature curing glass, and the mixed body is baked at the high temperature to form the first film. The layer 20 has a plurality of microbubble structures 21, and the microbubble structure 21 functions as a vacuum chuck to enhance the surface tension of the re-adhesive film 100 when the microbubble structure 21 is adhered to other surfaces.
