Current conducting silicon rubber with capability of electromagnetic shielding, and fabricating method

Abstract

This invention relates to an electrically conductive silicon rubber with electromagnetic shielding performance. The electrically conductive silicon rubber is prepared by: filling organosilicon rubber matrix with electrically and magnetically conductive media. The electrically and magnetically conductive media comprise: Ag powder 30-70 wt. %, Ni powder 0-40 wt. %, and magnetic powder 0-40 wt. %. The electrically conductive silicon rubber has such advantages as high weathering resistance, good mechanical properties, and high electromagnetic shielding performance.

Description

technical field

[0001] The invention relates to non-metallic functional materials, in particular to a conductive silicone rubber with electromagnetic shielding performance and a manufacturing method thereof. Background technique

[0002] In today's information society, with the development of electronic technology and computer technology, the number of electrical and electronic equipment used in a system has greatly increased, bringing more electromagnetic interference sources and sensors, and increasing potential interference; on the other hand , The miniaturization of the equipment makes the source and the source very close, which puts forward higher requirements for the control of electromagnetic interference. The World Health Organization has listed electromagnetic radiation as the fourth largest pollution. The United States and Europe have long formulated laws and regulations on the prevention of electromagnetic radiation, and Japan in Asia also has relatively complete...
