Abstract
The invention discloses a high-temperature-resistant and high-humidity-resistant electromagnetic shielding nylon material for electronic communication and a preparation method thereof, and belongs tothe field of polymer composite materials. The material comprises nylon resin, carbon fibers, a magnetic material, a composite antioxidant, a lubricant, a light stabilizer and a heat stabilizer. According to the invention, PA6T and MXD6 special nylon are used, carbon fiber reinforcement is carried out, and the magnetic filler is added, so that the problems of heat intolerance, moisture intoleranceand poor electromagnetic shielding of traditional nylon reinforced materials are overcome, and the material suitable for the field of electronic communication is prepared.
Description
technical field [0001] The invention relates to the field of polymer composite materials, in particular to a high-heat and high-humidity electromagnetic shielding nylon material for electronic communication and a preparation method thereof. Background technique [0002] The so-called electromagnetic shielding is a method to effectively suppress electromagnetic interference. Electromagnetic waves consist of electric and magnetic fields. Electric and magnetic fields are transmitted through space while vibrating alternately, generating electromagnetic waves. At a point far from the radiation source, the electric and magnetic fields vibrate on the surface perpendicular to the direction of travel, and the directions of vibration of the electric and magnetic fields are perpendicular to each other. Electromagnetic waves will be generated when electronic components work, and electromagnetic waves will interact with electronic components to generate electromagnetic interference. If...
