Problems solved by technology

However, in the base station (computer room) with many equipments, due to the large number of electromagnetic signal sources, the shielding performance of the ordinary aluminum-plastic composite tape containing only 1-2 layers of aluminum foil can no longer meet the requirements of use; a higher isolation performance is proposed for the product requirements

Embodiment Construction

[0024] Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0025] figure 1 The communication cable shown uses environmentally friendly conductive copper-aluminum foil shielding material, including an aluminum foil layer; there are two aluminum foil layers, namely the first aluminum foil layer 1 and the second aluminum foil layer 3; the aluminum foil layers are glued to the adjacent The first PET layer 2 bonded together by the aluminum foil layer, wherein the second aluminum foil layer is also bonded with the copper foil layer 5 through the second PET layer 4, and the other outer surface of the copper foil layer is bonded by the EMAA layer of glue 5 (ethylene-methacrylic acid copolymer layer); the EMAA layer acts as a self-adhesive layer in the cable (due to its viscosity at a certain temperature, it can be bonded to the inner surface of the cable sheath layer when the cable sheath layer is injected) .

Abstract

The present invention relates to shielding materials and a manufacturing method thereof. The objective of the invention is to provide improvement of environmental conductive copper and aluminum foil shielding materials for a communication cable and a manufacturing method thereof. The shielding materials have a higher isolation performance to meet a mobile communication shielding requirement. The manufacturing method is good in product flexibility, simple in preparation process and high in production efficiency. The environmental conductive copper and aluminum foil shielding materials for the communication cable comprise two aluminum foil layers. The environmental conductive copper and aluminum foil shielding materials further comprise a copper foil layer. PET layers glued and connected byglue are arranged between the two aluminum foil layers and between the copper foil layer and the aluminum foil layers, and the other external layer of the copper foil layer is an EMAA layer glued by glue.

Description

technical field [0001] The invention relates to a shielding material and a manufacturing method thereof, in particular to an environment-friendly conductive copper-aluminum foil shielding material for communication cables and a manufacturing method thereof. Background technique [0002] In recent years, with the rapid development of society, mobile communication products have been popularized and used in our country, and the base stations (computer rooms) correspondingly used have increased accordingly. In view of the special signal requirements of communication products, various electronic (electrical) components in the base station need to have a working environment that is moisture-proof and free of electromagnetic radiation. [0003] Conventional electronic products are electromagnetically isolated by covering the shielding layer. For example, the circumference of the cable products is all tightly covered with aluminum-plastic composite tapes to protect the electronic s...
