Abstract

The invention discloses a non-bright, anti-fingerprint and scraping-resistant single-side adhesive tape for conductive fabric and a preparation method and belongs to the technical field of electromagnetic wave shielding. The conductive fabric material is subjected to special processing, a polyurethane adhesive film is applied to the surface of the conductive fabric material, and then an ink processing layer and a functional coating are applied. The original material structure is changed, the toughness of the material is enhanced, so that the tensile strength of the product is improved, and the surface has the anti-fingerprint, scraping-resistant and solvent-resistant functions. The working efficiency of a user can be increased, and the fraction defective of the product is reduced; the adhesive tape has good electrical properties, physical properties and market application prospect; besides, the preparation method is simple in process and easy to operate and facilitates industrial popularization and application.

Description

technical field [0001] The invention relates to a matte anti-fingerprint, anti-scratch conductive cloth single-sided adhesive tape and a preparation method, belonging to the technical field of electromagnetic wave shielding. Background technique [0002] Due to the wide application of electronic technology, the rapid development and popularization of radio broadcasting, mobile phones, television, and microwave technology, the power of radio frequency equipment has doubled, and the electromagnetic radiation on the ground has increased significantly, which has reached the level of direct threat to human health. [0003] In electronic equipment and electronic products, electromagnetic interference (Electromagnetic Interference) energy is transmitted through conductive coupling and radiative coupling. In order to meet the requirements of electromagnetic compatibility, the conductive coupling needs to be suppressed by using filtering technology, that is, the EMI filter device is ...
