Abstract

The invention discloses an electromagnetic shielding coating. The electromagnetic shielding coating comprises 40 to 60 parts of polypyrrole, 2 to 10 parts of a curing agent, 10 to 30 parts of graphene fiber, 5 to 15 parts of Fe0.5Ni0.4Co0.1 powder microwave absorbent, and 2 to 5 parts of a color dye; wherein the graphene fiber is added in the form of graphene fiber bundles, and the graphene fiber bundles are vertically dispersed in polypyrrole so as to form an array with equal distances, and the Fe3O4 microwave absorbent is uniformly dispersed in epoxy resin. The electromagnetic shielding coating possesses excellent electromagnetic shielding performance and heat dissipation performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an electromagnetic shielding coating. Background technique [0002] With the rapid development of the electronic industry and communication industry, electronic and electrical equipment are widely used. Existing electrical equipment all has various electrical components. These electrical components generate electromagnetic radiation. Because the housing material of electronic equipment is generally plastic, electromagnetic waves can pass through freely, thereby causing electromagnetic pollution. In order to reduce the electromagnetic radiation of the devices and the mutual electromagnetic interference, it is necessary to metallize or conduct electricity to the plastic casing. Among them, conductive coatings have the advantages of low cost, easy automation and adaptation to complex shell shapes, and have the most development prospects. [0003] CN 103059672 A discloses an ele...
