Problems solved by technology

This common method can better transmit sound, but it also has a disadvantage. Because there is a through hole on the device, outside dust and moisture can easily enter the device through the through hole, especially when there is moisture from the outside It will greatly affect the life of the equipment, or even damage the product immediately
Even if it is not damaged, it will affect the quality of sound transmission

Embodiment 1

[0029] Such as figure 1 As shown, the present invention includes a waterproof breathable membrane 1, an adhesive layer A2 and a protective layer A3 arranged in sequence, and the waterproof breathable membrane 1 and the protective layer A3 are adhered together by the adhesive layer A2, and the protective layer A3 A hole is arranged on the top, and only the waterproof and breathable membrane 1 is covered at the hole.

[0030] When in use, peel off the protective layer A3 of this product corresponding to the size specification of the corresponding electronic product to be coated, and flush the waterproof and breathable membrane 1, so that the adhesive layer A2 and the electronic product to be coated are adhered together That's it.

[0031] Alternatively, the front of the waterproof and breathable membrane 1 is directly attached to the place where the electronic product is to be coated, and the protective layer A3 is always on the outermost side as the protective layer.

Embodiment 2

[0033] Such as figure 2 As shown, on the basis of Example 1, a support layer 4 is also included, and the support layer 4 is connected to the waterproof and breathable membrane 1 through the adhesive layer B5, and the support layer 4 and the adhesive layer B5 are also provided with corresponding holes.

[0034] When in use, peel off the protective layer A3 of this product corresponding to the size specification of the corresponding electronic product to be coated, so that the adhesive layer A2 and the electronic product to be coated can be adhered together.

Embodiment 3

[0036] Such as image 3 As shown, on the basis of Example 2, a protective layer B6 is also included, and the protective layer B6 is connected to the support layer 4 through the adhesive layer C7, and the protective layer B6 and the adhesive layer C7 are also provided with corresponding holes.

[0037] When in use, peel off the protective layer A3 of this product corresponding to the size specification of the corresponding electronic product to be coated, so that the adhesive layer A2 and the electronic product to be coated can be adhered together;

[0038] Alternatively, the protective layer B6 can be peeled off, so that the adhesive layer C7 and the electronic product to be coated can be adhered together.

[0039] In the above embodiment, the waterproof and breathable membrane 1 is a TPU puffed film or a polytetrafluoroethylene puffed film with a thickness of (0.01-0.5)±0.005mm; the adhesive layer A2 is made of waterproof foam glue or double Surface glue; the protective lay...

Abstract

The invention provides a multifunctional waterproof and air-permeable composite. The multifunctional waterproof and air-permeable composite comprises three layers of structures which are sequentially arranged and mutually connected, a waterproof and air-permeable membrane and a protective layer A are adhered together through an adhesive layer A, holes are formed in the protective layer A, and the holes are only covered with the waterproof and air-permeable membrane. The multifunctional waterproof and air-permeable composite has the advantages that according to the technical scheme, the multifunctional waterproof and air-permeable composite sticks to a through hole of an electronic product; on one hand, external water and dust can be effectively prevented from entering the interior of the electronic product; on the other hand, transmission of sound is not hampered.

Description

technical field [0001] The invention belongs to the field of die cutting, and in particular relates to a multifunctional waterproof and breathable composite material. Background technique [0002] With the progress of society, the use of electronic products has become more and more popular, and products such as recording pens, mobile phones, MP3 players, and earphones have entered thousands of households. Many electronic products have the function of sound transmission. In order to better record sound or transmit sound, some small holes are opened on the device, so that the sound can be smoothly transmitted from the outside to the inside of the device, or from the inside of the device. This common method can better transmit sound, but it also has a disadvantage. Because there is a through hole on the device, outside dust and moisture can easily enter the device through the through hole, especially when there is moisture from the outside When it is used, it will greatly affe...
