Problems solved by technology

[0004] However, at present, conventional electromagnetic shielding materials are difficult to balance the electromagnetic shielding effect and material thickness, that is, thicker materials have better electromagnetic shielding effects. In addition, conventional electromagnetic shielding materials have the technical problem of poor shielding effect on high-frequency electromagnetic waves.

Abstract

The invention discloses a high-frequency electromagnetic wave shielding material, and belongs to the technical field of electromagnetic shielding. The shielding material is composed of a release filmlayer, a back adhesive layer, a first alloy layer, a shielding base layer and a second alloy layer which are sequentially stacked. The electromagnetic wave shielding material comprises the shielding base layer, wherein the first alloy layer and the second alloy layer are prepared on the two sides of the shielding base layer respectively; the first alloy layer and the second alloy layer have excellent conduction performance and shielding performance, and especially have efficient shielding effect on high-frequency electromagnetic waves; the thickness of the shielding material is greatly reduced, so that a light and thin structure is achieved while the shielding effect is guaranteed; and the shielding material is simple in structure and easier to produce and prepare, and can be widely applied to connecting lines of a mobile terminal, a computer, medical equipment, a vehicle-mounted electric control system, a displayer and the like.

Description

technical field [0001] The invention belongs to the field of electromagnetic shielding, and relates to an electromagnetic shielding material, in particular to a multilayer high-frequency electromagnetic wave shielding material. Background technique [0002] In recent years, with the rapid development of science and technology and the electronic industry, various digital and high-frequency electronic equipment such as computers and radio communication equipment have been widely used. The voltage of electronic equipment changes rapidly during operation, and a large number of different Wavelength and frequency of electromagnetic waves, the electromagnetic interference caused by it is becoming more and more serious, and electromagnetic radiation has become another serious pollution source after air pollution and water pollution. [0003] The most convenient and effective way to suppress electromagnetic radiation is to use electromagnetic shielding materials to achieve electromag...
