Description

Technical Field

[0001] The utility model relates to the technical field of sponges, in particular to a sponge with an antistatic structure. Background Art

[0002] Antistatic sponge is a sponge material with antistatic function, mainly used in occasions where static electricity environment needs to be controlled, such as electronic product packaging, dust-free workshops, precision instrument protection, etc.

[0003] Reference can be made to the existing literature for a sponge with antistatic function (CN219405674U). The reference literature provides an antistatic layer, which can wrap the outer wall of the sponge main layer while utilizing the NFJ reinforcement layer, the polymer mica powder layer, and the antistatic material provided inside to effectively connect the sponge main layer while achieving good antistatic benefits on the surface of the sponge body, thereby preventing static electricity from being generated on its surface at will and improving the use effect of the sponge itself.

[0004] Currently, when making anti-static packaging for electronic devices, it is often necessary to connect multiple sponges. Generally, the multiple sponges need to be connected through external tools or glue coating, which is inefficient. Utility Model Content

[0005] The present invention aims to address the shortcomings of the prior art by providing a sponge with an antistatic structure. By bonding EVA conductive foam to the narrower middle portion of an I-shaped IXPE conductive foam, the combined use of the EVA and IXPE conductive foams provides a superior antistatic effect. Furthermore, the bonded EVA conductive foam is replaceable, and when used for electronic device packaging, two or more sponges can be longitudinally bonded using a second adhesive layer to increase the overall thickness of the sponge, enabling rapid provision of an antistatic sponge of appropriate size for electronic devices as needed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A sponge with an antistatic structure comprises: IXPE conductive foam, wherein the IXPE conductive foam serves as a main body and is provided with a second adhesive layer at both the upper and lower ends, through which two sponges are longitudinally bonded; and a first adhesive layer is provided on the inner side of the IXPE conductive foam and is connected to EVA conductive foam via the first adhesive layer.

[0008] The utility model is further configured such that the IXPE conductive foam is arranged in an I-shape, a narrower middle portion is provided with a first adhesive layer, and the EVA conductive foam is bonded to the middle portion.

[0009] The utility model is further configured such that when the sponge is not in use, the surface of the second adhesive layer is connected with a second waterproof membrane.

[0010] The utility model is further configured such that when the sponge is not in use, the IXPE conductive foam is connected to a No. 1 waterproof film on the No. 1 adhesive layer.

[0011] The utility model is further configured such that the end portions of the No. 1 waterproof membrane and the No. 2 waterproof membrane are respectively provided with a first protrusion and a second protrusion.

[0012] The utility model is further configured such that three protrusions are provided on the surface of the EVA conductive foam.

[0013] The beneficial effects of the utility model are:

[0014] 1. When anti-static packaging is performed on electronic equipment, multiple sponges can be quickly bonded together longitudinally as needed. Since each sponge is provided with a second adhesive layer at the upper and lower ends, after tearing off the second waterproof film on the surface of the second adhesive layer, the second adhesive layer can be used to connect them longitudinally. No additional tools or glue are required, and the operation is convenient.

[0015] 2. The anti-static structure uses IXPE conductive foam as the main anti-static structure, and the outer layer is EVA conductive foam. The EVA conductive foam and IXPE conductive foam have a double-layer anti-static effect. At the same time, the outer layer of EVA conductive foam can be torn off and replaced.

[0025] Reference Figure 1-4, a sponge with an antistatic structure, comprising: IXPE conductive foam 1, IXPE conductive foam 1 as the main part, with a second adhesive layer 3 provided at the upper and lower ends, the two sponges are longitudinally bonded by the second adhesive layer 3, the inner side of the IXPE conductive foam 1 is provided with a first adhesive layer 8 and connected to an EVA conductive foam 5 through the first adhesive layer 8, IXPE conductive foam 1 as the main antistatic layer of the sponge, IXPE conductive foam 1 is IXPE foam with conductive filler added, the conductive filler can be carbon black, metal powder or other conductive substances, the addition of conductive filler can form a conductive network inside the foam, thereby giving it antistatic ability, and the second adhesive layer 3 is provided at the upper and lower ends of the IXPE conductive foam 1, so that Two adjacent sponges can be longitudinally bonded through the No. 2 adhesive layer 3, which is convenient for connection and combination in anti-static packaging. At the same time, the IXPE conductive foam 1 adopts an I-shaped design, which is wide at the top and bottom and narrow in the middle. The No. 1 adhesive layer 8 is provided in the narrower gap in the middle. The No. 1 adhesive layer 8 can be bonded to the EVA conductive foam 5. The EVA conductive foam is formed by adding conductive carbon powder filler during the molding process of the EVA foam and is formed by molded foaming. This treatment makes the EVA material have permanent anti-static properties and is not affected by the dryness and wetness of the environment. Therefore, the bonded EVA conductive foam 5 is used in combination with the IXPE conductive foam 1, so that the sponge has double-layer anti-static properties. When the outer layer of the EVA conductive foam 5 is worn, it can be torn off and replaced.

[0026] When the sponge is not in use, the surface of the No. 2 adhesive layer 3 will be connected with the No. 2 waterproof membrane 4, which can block water vapor and dust and ensure the stickiness of the No. 2 adhesive layer 3. When it needs to be used, the No. 2 waterproof membrane 4 can be torn off.

[0027] At the same time, a protrusion 2 7 is provided on one corner of the second waterproof membrane 4 , and the protrusion 2 7 facilitates the rapid tearing off of the second waterproof membrane 4 .

[0028] When the sponge is not in use, a waterproof membrane 2 is provided on the surface of the adhesive layer 8. The waterproof membrane 2 can ensure the stickiness of the adhesive layer 8. At the same time, a protrusion 6 is provided at the end of the waterproof membrane 2. The waterproof membrane 2 can be torn off by pulling the protrusion 6.

[0029] For further information, please refer to Figure 1-2 After tearing off the No. 1 waterproof film 2, the EVA conductive foam 5 can be bonded. The EVA conductive foam 5 is provided with a protrusion 9 on the surface, which is convenient for quickly tearing off the EVA conductive foam 5 for replacement.

[0030] Working principle: When using the utility model, when electronic equipment is packaged for anti-static purposes, multiple sponges can be quickly bonded longitudinally as needed. Since a No. 2 adhesive layer 3 is provided at the upper and lower ends of each sponge, after tearing off the No. 2 waterproof film 4 on the surface of the No. 2 adhesive layer 3, the No. 2 adhesive layer 3 is used for longitudinal connection. No additional tools or glue coating are required, and the operation is convenient. IXPE conductive foam 1 is used as the main anti-static structure, and the outer layer is EVA conductive foam 5. The EVA conductive foam 5 cooperates with the IXPE conductive foam 1 to achieve a double-layer anti-static effect. At the same time, the outer layer of EVA conductive foam 5 can be torn off and replaced.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
