Problems solved by technology

Although the plastic sheet can effectively reduce the water pressure to avoid delamination of the composite membrane when water directly hits the composite membrane, due to its poor waterproof performance, more water will still flow to the membrane through the openings, and then seep into the membrane. Leakage into the cavity leads to test failure, failing to meet the required IPX5 or IPX6 waterproof level

Embodiment 1

[0042] refer to Figures 1 to 3 As shown, the waterproof and breathable member in this embodiment includes the first PTFE membrane 100 facing the incoming water side and the PTFE composite membrane 200 facing away from the incoming water side. Adhesive portion 120, PTFE composite membrane 200 comprises base material 210 and the second PTFE membrane 220 that is arranged on the base material 210, base material 210 is arranged on the water side away from, the second PTFE membrane 220 and one side of the first PTFE membrane 100 There is a first adhesive layer 300 bonded to the adhesive portion 120 between them, and the other side of the first PTFE membrane 100 is provided with a second adhesive layer 400 bonded to the adhesive portion 120, the first adhesive layer 300 and the second adhesive layer 400 The two adhesive layers 400 are both ring-shaped.

[0043] In this embodiment, when the waterproof and breathable member is tested for IPX5 or IPX6 waterproof level, since water fir...

Embodiment 2

[0053] Such as Figure 4 As shown, the present invention also provides a waterproof casing 600. The waterproof casing 600 is provided with a through hole 610 connecting the inner cavity of the casing and the outside world. The waterproof and breathable member described in Embodiment 1 is installed in the waterproof casing 600. The second adhesive layer 400 is bonded to the inner wall of the waterproof housing to cover the through hole 610 , wherein the inner diameter of the second adhesive layer 400 is larger than the diameter of the through hole 610 . In other embodiments, the second adhesive layer can also be bonded to the outer wall of the waterproof casing to cover the through hole, but compared with this fixing method, in this embodiment, the waterproof and breathable member is installed in the waterproof casing, which can ensure The appearance of the waterproof casing can also play a good role in protecting the waterproof and breathable components, preventing them from f...

Abstract

The invention discloses a waterproof breathable component, and belongs to the technical field of membranes. The waterproof breathable component comprises a first PTFE (polytetrafluoroethylene) membrane facing a water incoming side and a PTFE composite membrane back to the water incoming side, the first PTFE membrane comprises a breathable part and a bonding part surrounding the breathable part, the PTFE composite membrane comprises a base material and a second PTFE membrane arranged on the base material, the base material is arranged back to the water incoming side, a first adhesive layer bonded on the bonding part is arranged between the second PTFE membrane and one surface of the first PTFE membrane, and a second adhesive layer bonded on the bonding part is arranged on the other surfaceof the first PTFE membrane. According to the waterproof breathable component, by arranging the first PTFE membrane and the PTFE composite membrane, the waterproof grade of IPX5 or IPX6 can be achieved. In addition, the invention further discloses a waterproof shell adopting the waterproof breathable component.

Description

【Technical field】 [0001] The invention relates to the field of membrane technology, in particular to a waterproof breathable component and a waterproof casing. 【Background technique】 [0002] Waterproof and breathable film is mainly used on electronic components of outdoor communication base stations, mainly RRU, filter, tower amplifier, combiner, power amplifier, duplexer, antenna and sensor, etc. Compared with waterproof and breathable valves, waterproof and breathable film can better meet the trend of miniaturization of outdoor electronic equipment such as communication base stations. However, the existing waterproof and breathable film cannot reach the IPX5 or IPX6 waterproof grade required by major communication equipment manufacturers. [0003] For example: a waterproof and breathable film is disclosed in the prior art, which includes a first soft rubber layer, a single film layer, a second soft rubber layer and a support layer, the first soft rubber layer is laminate...
