Problems solved by technology

[0002] With the substantial increase of electronic and electrical products, while bringing convenience to people, it also brings electromagnetic pollution to people, causing great harm to people's health, and also causes interference and signal to electronic equipment and instruments. Distortion, mistakes, and even major accidents, how to protect the human body from electromagnetic radiation, and electronics, instruments and equipment from interference, has become a hot research topic in the scientific and technological circles and business circles of all countries in the world. The existing shielding materials, Such as steel plate, copper mesh (braided copper wire), and electroless nickel-plated mesh can solve the shielding technical problems of general electronic equipment and shielding rooms, but

Example Embodiment

[0017] The present invention will be further described below in conjunction with the embodiments. Example 1: Preparation of nickel-plated polyester-based conductive mesh cloth, the steps are as follows:

[0018] (1) Matrix, PET polyester fiber woven mesh, thickness 0.09mm, 105g / m 2 , The mesh is square, the mesh number is 90 mesh / inch, and the monofilament diameter is 0.045mm.

[0019] (2)Vacuum nickel plating: the substrate is protected by argon gas, and the temperature of nickel plating is 180℃, and the vacuum degree of the vacuum chamber is 5×10 -5 Pa, substrate moving speed 1.5m / min, ion sputtering degree 1.5g / m 2 .

[0020] (3) Then use the existing plastic electroplating technology to continuously plate a layer of nickel on the above materials, and finally cover and plate a layer of chromium to form a black polyester-based conductive mesh cloth. Example 2. As described in Example 1, the difference is: in step (3), the last layer of black metal is black nickel. Example 3. As ...

Abstract

The preparation method of polyester base conductive net fabric belongs to the field of evaporative deposition and electroplating technology. Said method includes the following steps: depositing nickel or copper on polyester base net fabric by using evaporative deposition process, then continuously electroplating nickel or/and copper, finally, covering and electroplating a layer of black metal. Said invented polyester base conductive net fabric has high light transmittancy, can be used as electromagnetic wave shielding material of plasma TV front panel, handset shielding and window shielding material.
