Detailed Description
In order to make the objects and advantages of the present invention more apparent, the present invention will be described in detail with reference to the following examples. It should be understood that the following text is used to describe only one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the specific claims.
As shown in fig. 1-4, a waterproof and breathable membrane assembly comprises a base membrane 1 and a dropper, wherein the upper surface of the base membrane 1 is provided with a breathable layer 2, the upper surface of the breathable layer 2 is connected with a waterproof layer 3, the upper surface of the waterproof layer 3 is connected with a release membrane 4, the side edges of the breathable layer 2 and the waterproof layer 3 are adhered with filling glue 9, and the lower surface of the base membrane 1 is provided with a side edge reinforcing structure at the edge;
The side reinforcing structure comprises a filling groove 5 formed in the lower surface of the base layer film 1, a plurality of protruding blocks 6 are connected to the upper surface of the filling groove 5, the protruding blocks 6 are trapezoid, and a plurality of micropores 7 are formed in the side of the filling groove 5.
Specifically, after the base layer film 1 is adhered to the equipment, a proper amount of curing glue can be taken by using a dropper and injected into the filling groove 5, and the edge of the base layer film 1 is subjected to secondary sealing and fixing treatment, so that the laminating degree and the sealing property between the base layer film 1 and the equipment can be ensured, the firmness can be further improved, the equipment can be operated underwater for a long time, and the using effect of the equipment can be further improved.
As shown in fig. 1-2, a plurality of anti-pressing blocks 8 are adhered between the ventilation layer 2 and the base layer film 1.
Specifically, the anti-pressing block 8 forms a certain gap between the breathable layer 2 and the base layer film 1, when the waterproof film is used under deep water, if the waterproof film is deformed due to deep water pressure, the waterproof layer 3 and the breathable layer 2 can be compressed towards the gap, meanwhile, the wrapping structure of the base layer film 1 is matched, so that the whole body is tightened inwards, and the side reinforcing structure is combined, so that the whole service performance of the waterproof film is not affected.
As shown in fig. 1-2, the base layer film 1 is wrapped, and the air permeable layer 2 and the waterproof layer 3 are both positioned on the inner side of the base layer film 1.
Specifically, the overall structure of the base layer film 1 is equivalent to a box body with the top not closed, and the ventilation layer 2 and the waterproof layer 3 are both positioned in the base layer film 1, so that the overall compression resistance of the waterproof film can be effectively enhanced, and even when the waterproof film is operated underwater, the waterproof film can not be deformed to generate gaps and other problems due to underwater pressure, so that the waterproof film is uniformly stressed underwater, and the protection life of electronic equipment is prolonged.
As shown in fig. 2, the filling glue 9 is filled between the breathable layer 2 and the waterproof layer 3 and the base layer film 1, and the side of the filling glue 9 near the base layer film 1 is provided with a bulge.
Specifically, after the breathable layer 2 and the waterproof layer 3 are assembled, glue needs to be poured between the breathable layer 2 and the waterproof layer 3 and the base layer film 1 for filling gaps generated between the breathable layer 2 and the waterproof layer 3, so that the water is prevented from penetrating into the gaps, and the waterproof effect is further achieved due to the connection performance between the structures on the two sides.
As shown in fig. 3, the dropper includes a rubber cap 11 and a tapered tube 12, the tapered tube 12 communicating with the rubber cap 11.
The dropper can be used by adopting the conventional dropper in the prior art, so that the detailed description is not needed in the scheme; it should be noted, however, that the extrusion end of the dropper needs to be relatively sharp in order to facilitate the delivery of glue into the micro-holes 7 and filling into the filling grooves 5 to create a curing effect.
As shown in fig. 2, a release liner 10 is adhered to the lower surface of the release film 4.
Specifically, the release adhesive 10 has the main function of forming an isolation layer between two surfaces to prevent adhesion; the functions also include:
Anti-sticking: the release liner 10 can prevent adhesion between two surfaces of objects. The isolation layer formed by the method can enable the two surfaces to be easily separated after being contacted, and the two surfaces cannot be stuck together;
The protection surface: the release liner 10 may provide protection to the surface of the object. It can form a film on the surface of an object to prevent scratches, corrosion or other physical and chemical damage;
Residue reduction: the release liner 10 generally has low residue and is easy to clean after use without leaving significant marks or residues on the adherend. This is important for applications where it is desirable to keep the surface clean and not to interfere with subsequent processes.
In the scheme, the release adhesive 10 is used by being matched with the release film 4 and is used for protecting the surface of the waterproof layer 3; secondly, the release adhesive 10 can also protect the lower surface of the base film 1 through the release adhesive 10.
