Problems solved by technology

However, this kind of sandwich-type decorative and shielding integrated wallpaper is connected by metal buckles during construction. The two adjacent wallpapers become an integrated conductor through the metal buckle and are processed by crimping. The construction is difficult and prone to technical problems. , the construction process is cumbersome, and due to the thickness of the material, it is easily affected by the stress of the wallpaper itself under the yin and yang corners to cause creep deformation, the pore size of the production fabric becomes larger, and the shielding effect is reduced
[0007] Since the thickness (gram weight) of the metal (plating) layer is directly proportional to the shielding effectiveness, if the pattern is directly printed on the metal fabric or the organic metal coating fabric, due to the small surface tension of the shielding material, it cannot meet the requirement of adding another layer of printing layer. Focusing on the demand, it is easy to cause the printing layer to fall off, and even cause problems such as the peeling of the fabric and the metal coating, and the service life is short

Abstract

The invention relates to a broadband dual-shielding functional decorative wallpaper and a construction method thereof. The wallpaper is composed of a basic material layer with an electromagnetic shielding performance, a coupling layer, and a decorative surface layer. The coupling layer is arranged between the basic material layer and the decorative surface layer. The basic material layer is composed of metal coated conductive fabrics, metal filament fabrics, blended fabrics of metal filaments and chemical fibers, or metal coated chemical fiber fabrics. The coupling layer is composed of chromium complexes, titanate / silane coupling agent, and coupling agent carrier compounds. The wallpaper can be divided into a single naked edge type, a dual naked edge type, and a full edge type. In construction, the single naked edge type wallpaper can be assembled in sequence; or the single naked edge type wallpaper, the dual naked edge type wallpaper, and the full edge type wallpaper can be assembled in sequence. The wallpaper is subjected to a coupling treatment. The adhesion force of the decorative surface layer on the wallpaper surface is enhanced. The beauty of the wallpaper is strengthened. According to the construction method, the corners of walls and the naked edges between neighbored wallpaper are covered by a shielding layer to prevent wave leakage and the shielding effect is improved.
