Description
Technical Field
The utility model relates to the field of gauze for electronic products, in particular to an anti-layering multilayer composite gauze bonding structure.
Background
With the continuous progress of science and technology, nowadays, various electronic products have more and more abundant functions, and many electronic products have special requirements on appearance. Individual products require a multilayer composite gauze composed of metal gauze and common non-metal gauze as an appearance piece or used in the product, and the gauze can be seen through the through holes on the outer side of the product. The multilayer composite gauze is a sintering gauze product with wide application, and has the performances of stable filtering precision, high strength, easy cleaning and the like which are not comparable with other gauzes.
When the electronic product selects the multilayer composite gauze as one layer of material, the adhesion degree of the electronic product and the adhesive tape is not high, and the problems of degumming, layering and falling off easily occur. Meanwhile, in a product with high requirement on air tightness, the requirement on sealing is met, and the gauze can be seen from the outer side of the product, so that the requirement is difficult to meet by the traditional structure. The edges of the multilayer composite gauze are easy to ventilate, so that the whole product can not meet the sealing requirement. Becomes a pain point in the design of a plurality of products.
When the multilayer composite gauze is attached to the inner side of the product, the gauze which is contacted with the outside through the through hole plays a role in beautifying the appearance, and has the function of filtering fine particles. The structure of the composite screen is generally the same as that of the upper layer and the lower layer of glue. As shown in fig. 1. The first layer of double faced adhesive tape 1 is bonded with the A face of the multilayer composite gauze 4, the B face of the multilayer composite gauze 4 is bonded with the second layer of double faced adhesive tape 2, the upper layer and the lower layer of adhesive tape bond the multilayer composite gauze in the middle, the first layer of double faced adhesive tape 1 is bonded on the inner side of the product shell 4, the A face of the multilayer composite gauze is enabled to be leaked, and the size of the multilayer composite gauze 4 is the same as that of the upper layer of double faced adhesive tape and that of the lower layer of double faced adhesive tape.
The A surface of the multilayer composite gauze is common non-metal gauze; the B surface of the multilayer composite gauze is a metal gauze. When the exposed a-side of the multi-layer composite veil is used only as an appearance part and good sealing of the product is required, there is a risk that the edge θ in the structure of fig. 1 will be air-permeable and will not be sealed. This is because the adhesive strength between the adhesive tape and the multi-layer composite gauze composed of the metal mesh and the common gauze is not high, and the adhesive tape is easily permeable to air at the edge, so that the sealing requirement of the whole product cannot be met.
