Abstract

The invention discloses electromagnetic shielding paint. The electromagnetic shielding paint comprises 40-60 parts of polypyrrole, 2-10 parts of curing agent, 10-30 parts of graphene fiber, 5-15 parts of Fe3O4 microwave absorbent and 2-5 parts of color dye, wherein graphene fiber bundles are used as graphene fiber and vertically dispersed in polypyrrole to form a uniformly-spaced array, and the Fe3O4 microwave absorbent is uniformly dispersed in epoxy resin. The electromagnetic shielding paint has high electromagnetic shielding performance and high heat dissipating 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...
