Alternatively, the burst disk includes a release film 10, a substrate 30, a first offset pattern layer 71, a resin fabric composite layer 20, a second offset pattern layer 72, a coating layer 50, and an ink layer 60. The release film 10 includes a first release film 11 and a second release film 12, and the first release film 11, the base material 30, the first offset pattern layer 71, the resin fabric composite layer 20, the second offset pattern layer 72, the coating layer 50, the ink layer 60, and the second ink layer are sequentially disposed. Of course, the explosion-proof film may be provided with only the offset pattern layer 70 on both sides of the resin fabric composite layer 20 without providing the plating layer 50 and the ink layer 60.
The rupture membrane provided in the embodiment of the present application enriches the pattern and color matching of the preset texture by providing the offset pattern layer 70 so as to form the preset texture on the resin fabric composite layer 20.
A housing according to an embodiment of the present application is described below in connection with fig. 5-7.
Embodiments of the present application also provide a housing comprising a substrate 100 and an explosion-proof membrane as described above. The rupture disc is bonded to the substrate 100.
As shown in fig. 5 and 6, when the rupture disk has the adhesive layer 40 or the rupture disk includes the base material 30 and the base material 30 itself has the adhesive layer, the release film 10 is peeled off and then directly adhered to the base body 100. In the case where the burst disk does not have the adhesive layer 40 or the burst disk includes the substrate 30 and the substrate 30 itself is not provided with the adhesive layer, the burst disk is adhered to the base 100 by UV glue after the release film 10 is peeled off. For example, when the substrate 100 is glass, the rupture membrane is bonded to the substrate 100 by OCA adhesive.
As shown in fig. 6, in the case where the rupture disk includes the plating film layer 50 and the ink layer 60, the rupture disk is manufactured in advance and then bonded to the substrate 100; or, in the process of preparing the rupture disk, the semi-finished rupture disk is adhered to the substrate 100, and then the coating layer 50 and the ink layer 60 are formed on the surface of the resin fabric composite layer 20 through technological operation. Similarly, as shown in fig. 7, in the case where the burst disk includes the offset pattern layer 70, the coating layer 50 and the ink layer 60, the burst disk manufactured in advance may be directly bonded to the substrate 100, or the semi-finished burst disk may be bonded to the substrate 100 first, and then the offset pattern layer 70, the coating layer 50 and the ink layer 60 may be formed by a process operation.
Alternatively, the substrate 100 is attached to the burst membrane in a sheet-to-sheet or roll-to-roll manner. Wherein, the shell is a plastic shell or a plate shell, and a machine tool or laser engraving cutting with a preset size is needed after the base body 100 is attached to the rupture membrane. If the shell is a three-dimensional plastic part or a three-dimensional plate part, hot-pressing the wire after the base body 100 is attached to the rupture membrane, and then cutting by a machine tool or laser etching with a preset size.
In addition, the embodiment of the application also provides electronic equipment, which comprises the shell.
The electronic equipment is electronic products such as a smart phone, a notebook computer, a tablet personal computer and an intelligent pen, and the appearance texture of the electronic equipment is improved by using the shell.
The embodiment of the application also provides a preparation method of the rupture disc, which is to place the fabric on the first release film 11, infiltrate the fabric with resin by means of dispensing or dipping, and cure the fabric to form the resin fabric composite layer 20. A predetermined texture is formed on a side of the resin fabric composite layer 20 remote from the first release film 11. The second release film 12 is laminated on the side of the resin fabric composite layer 20 remote from the first release film 11 to form an explosion-proof film.
The resin can fully fill gaps among yarns of the fabric after the fabric is soaked by the resin, so that the explosion-proof film has no flaws such as bubbles, wrinkles, flow marks and the like.
In an alternative embodiment, the fabric is placed directly on the first release film 11, the resin is impregnated into the fabric by dispensing or dipping, and the curing process is performed to form the resin fabric composite layer 20. In yet another alternative embodiment, the substrate is placed on the first release film 11 and then the fabric is placed on the substrate. The resin is then impregnated into the fabric by dispensing or dipping, and cured to form the resin fabric composite layer 20.
In the case that the base material 30 does not have the adhesive layer 40, for facilitating the adhesion of the rupture membrane to other structures, the resin fabric composite layer 20 is prepared first, then the adhesive layer 40 is formed by coating a layer of glue on the base material 30, and then the resin fabric composite layer 20 and the adhesive layer 40 are composited in a roll-to-roll or sheet-to-sheet manner; or, firstly, coating a layer of glue on the base material 30 to form an adhesive layer 40, then placing the base material 30 on the first release film 11 to enable the adhesive layer 40 to be attached to the first release film 11, then placing the fabric on the non-adhesive side of the base material 30, then soaking the fabric by means of dispensing or dipping, and curing to form the resin fabric composite layer 20.
In one embodiment of the present application, forming the predetermined texture on the side of the resin fabric composite layer 20 away from the first release film 11 further includes:
forming a preset texture on the side of the resin fabric composite layer 20 away from the first release film 11 through a compression roller process; alternatively, a predetermined texture is formed on a side of the resin fabric composite layer 20 remote from the first release film 11 through a UV transfer process.
In an alternative embodiment, to form the predetermined texture on the surface of the resin fabric composite layer 20, press-fitting is performed using a press roller having the predetermined texture, so that the predetermined texture is formed on the surface of the resin fabric composite layer 20 by means of a press roller process. Or, the surface of the first release film 11 is provided with a preset texture, and the preset texture on the first release film 11 is printed on the surface of the resin fabric composite layer 20 in the pressing process of the pressing roller.
In still another alternative embodiment, the resin fabric composite layer 20 is formed by press-fitting and fixing, and then the offset pattern layer 70 is formed as a preset texture on one side or both sides of the resin fabric composite layer 20 by a UV transfer process to enrich the pattern and color of the preset texture.
On the basis of the above embodiment, in order to further enhance the texture, the coating layer 50 is formed on the pre-set texture side of the resin fabric composite layer 20 by an optical coating process, and the ink cover bottom is formed on the side of the coating layer 50 away from the resin fabric composite layer 20 by screen printing to form the ink layer 60.
