Problems solved by technology

However, the PVC layer is non-degradable, and the extensive use of PVC results in a large amount of non-degradable industrial or domestic waste, which is not conducive to environmental protection
In order to solve environmental problems, some fabrics are used instead of PVC. The existing shielding clothing fabrics mostly use this technology, but the physical properties of the fabrics are not good, especially the anti-fouling performance. Frequent rinsing of the fabrics will reduce the conductivity. Cloth shielding properties

Abstract

The present invention relates to a shielding material and also relates to a shielding cloth material. The shielding material has a laminar structure and comprises conductive cloth, TPU film and release material layer. The TPU film and release material layer are adhibited on two surfaces of conductive cloth through two adhesive layers. The TPU film is provided with a printing layer which is installed on the surface that faces to the conductive cloth. The shielding cloth material comprises the conductive cloth. The surface of conductive cloth is attached with the TPU film which is provided with the printing layer that is installed on the surface facing to the conductive cloth. Because the TPU has excellent air permeability and is water-proof, the people feel comfortable when the TPU is used as clothes and the dirt is easily eliminated. The shielding material is suitable for the group with shielding requirement, and is especially suitable for the group with electromagnetic wave shielding requirement. The present invention provides an electromagnetic wave shielding material with the advantages of excellent physical property and environment protection. The invention also provides the shielding cloth material which is suitable for environment protection.

Description

technical field [0001] The invention relates to a shielding material, in particular to an environment-friendly electromagnetic wave shielding material with good physical properties, and also to a shielding clothing fabric. Background technique [0002] Conductive cloth has the function of shielding electromagnetic waves, but it cannot be used directly for non-industrial purposes. On the one hand, it is because of its poor physical properties, and on the other hand, direct use is easy to scratch or wear the conductive cloth, which affects the shielding effect. The physical properties mentioned here refer to the characteristics of materials in terms of air permeability, waterproof, scratch resistance, and stain resistance. [0003] In order to solve the above problems, PVC is generally coated or pasted on the surface of the conductive cloth to make a film for use. However, the PVC layer is non-degradable, and the extensive use of PVC results in a large amount of non-degradabl...
