Abstract

The invention relates to an anti-shielding conductive coating. The conductive coating comprises 20-25wt% of acrylic resin, 15-20wt% of conductive powder, 1.5-3.5wt% of aids and 57-63wt% of solvent. The anti-shielding conductive coating has excellent adhesiveness and is suitable for coating electromagnetic shielding coatings on the surfaces of mobile phones, notebook computers and audiovisual instruments. Films formed by coating the coating have good adhesive forces, are easy to construct and are thick. Anti-shielding conductive films can be formed after the anti-shielding conductive coating is coated.

Description

technical field [0001] The invention belongs to the technical field of coatings, more specifically, the invention relates to an anti-shielding conductive coating with excellent adhesion. Background technique [0002] With the continuous development of electronic information technology, electronic products have been more and more widely used in various fields of industry and family life. The generation, transmission, reception and processing of electronic information must use electromagnetic waves as the carrier. On the one hand, electromagnetic waves play an important role as the carrier of information transmission; on the other hand, the wide application of electronic and electrical products in the information age forms a complex electromagnetic environment, which also leads to negative effects such as electromagnetic interference and electromagnetic radiation. Therefore, in order to ensure the normal operation of electronic and electrical equipment and protect human health...
