The utility model aims to provide a shielding material coated with hot melt adhesive, wherein a drainage copper wire can be directly contacted with an aluminum foil layer, and the drainage effect is good.
In order to achieve the purpose, the technical scheme provided by the utility model is as follows:
a hot melt adhesive coated shielding material comprising: the aluminum foil layer and the coating are in the hot melt adhesive layer on the surface of the aluminum foil layer, and the hot melt adhesive layer is provided with a plurality of hollow grooves.
The aluminum foil is characterized by further comprising a polyester tape layer and a composite adhesive layer, wherein the hot melt adhesive layer is arranged on the upper surface of the aluminum foil layer, and the polyester tape layer is bonded on the lower surface of the aluminum foil layer through the composite adhesive layer.
Furthermore, the hollow grooves are communicated with each other, so that the hot melt adhesive layer forms a plurality of hot melt adhesive blocks.
Further, the hot melt adhesive block is polygonal, circular or elliptical.
Or the plurality of hollow-out grooves are mutually independent, so that the hot melt adhesive layer is of a net structure.

Detailed Description
The drawings are only for the purpose of clearly and clearly showing the structure of the utility model, and the length, thickness and proportional relation of the parts of the utility model are not limited in the drawings.
The utility model is further described with reference to the following drawings and detailed description.
Example one
As shown in FIG. 1, the hot melt adhesive coated shielding material of the present invention comprises: aluminium foil layer 3, the coating is at the hot melt adhesive layer 4 on 3 surfaces on aluminium foil layer, and hot melt adhesive layer 4 is equipped with a plurality of fretwork grooves 5.
In this embodiment, the hollow grooves 5 are communicated with each other, so that the hot melt adhesive layer 4 forms a plurality of hot melt adhesive blocks 6. The hot melt adhesive blocks 6 are independent from each other and do not contact with each other, and the shapes of the hot melt adhesive blocks are polygonal, circular or elliptical. When the shielding material of the utility model is actually produced and manufactured, the hot melt adhesive blocks 6 are coated on the aluminum foil layer 3 discontinuously, so that the mutually communicated hollow-out grooves 5 are enclosed between the hot melt adhesive blocks 6. Due to the arrangement of the hollow-out grooves 5, a part of the aluminum foil layer 3 is exposed, the copper wire can be in direct contact with the aluminum foil layer 3 through the hollow-out grooves 5, so that the drainage effect is enhanced, the drainage copper wire can conduct out corresponding induced current, and the phenomenon that the generated induced current is converted into an electromagnetic field to influence the transmission of signals when the shielding material absorbs and reflects electromagnetic waves is avoided. The mutually communicated hollow grooves 5 are in strip structures matched with copper wires, and the aluminum foil layer 3 at the hollow grooves 5 is easy to contact with the copper wires.
Example two
As shown in fig. 2, the structure of the present embodiment is similar to that of the first embodiment, except that the plurality of hollow-out grooves 5 are independent from each other, so that the hot melt adhesive layer 4 is in a net structure. The hollow-out grooves 5 are polygonal, circular or elliptical, and the plurality of hollow-out grooves 5 are uniformly distributed on the hot melt adhesive layer 4, so that when the shielding material is bonded on other parts, the bonding strength of all parts is consistent, and the stable bonding performance is ensured. The design of the hollow-out groove 5 in this embodiment enables the hot-melt adhesive layer 4 to maintain integrity, and the hot-melt adhesive layer 4 provided with the hollow-out groove 5 is still a continuous whole, so that the firm bonding performance of the shielding material can be ensured, and the occurrence of edge warping and edge warping can be prevented.
EXAMPLE III
As shown in fig. 3 and 4, this embodiment has a similar structure to that of the first and second embodiments, except that a hot melt adhesive layer 4 is disposed on the upper surface of an aluminum foil layer 3, and the lower surface of the aluminum foil layer 3 is bonded with a polyester tape layer 1 through a composite adhesive layer 2. The polyester belt layer 1 is mainly a PET film, has good chemical resistance, moisture resistance, high temperature resistance and insulating property, has certain toughness and is not easy to tear.
