Heat-conducting wave-absorbing gasket

Abstract

The invention discloses a heat-conducting wave-absorbing gasket which is of a multi-layer structure and comprises at least two heat-conducting wave-absorbing layers and at least one conductive flexible layer, and at least one conductive flexible layer is not arranged on the outermost side of the heat-conducting wave-absorbing gasket. According to the invention, the conductive flexible layer is introduced between the heat-conducting wave-absorbing layers; the electromagnetic wave absorption mechanism of the heat-conducting wave-absorbing gasket is electromagnetic wave-heat and electromagnetic wave-high-frequency current, wherein the conductive flexible layer has a relatively strong reflection effect on electromagnetic waves, so that the electromagnetic waves can repeatedly penetrate throughthe heat-conducting wave-absorbing material, thereby improving the absorption capability of the heat-conducting wave-absorbing gasket on the electromagnetic waves, and solving the problem that the absorption effect of the heat-conducting wave-absorbing gasket on low-frequency electromagnetic waves is relatively weak.

Description

technical field [0001] The invention relates to a wave-absorbing material, in particular to a heat-conducting wave-absorbing pad. Background technique [0002] With the rapid development of information technology in our country, the application of electromagnetic wave technology in modern fields such as communication, broadcasting and network is becoming more and more extensive. The interference of electromagnetic wave noise on various electronic equipment and the harm to human health have gradually attracted widespread attention from all over the world. Therefore, absorbing materials have been widely used in electronic products to reduce or weaken electromagnetic interference caused by electromagnetic radiation. At present, the wave-absorbing materials on the market are mainly magnetic wave-absorbing agents. Although they have good wave-absorbing properties, their thermal conductivity is generally low (0.5-1W / (m·K)). [0003] With the development of electronic products tow...
