Problems solved by technology

1. The bonding force is not good, the product is unstable, and the phenomenon of metal particles falling off is prone to occur, resulting in a short circuit in the electrical circuit.
2. Insufficient softness and relatively hard, which is not conducive to installation and use in complex electronic equipment
3. The process flow is long and complicated, and the electroless plating process system is unstable and easy to decompose, which is difficult to control in continuous and large-scale production
4. Electroplating process: the surface density uniformity is not good, and it is difficult to accurately control the uniformity of the metal coating
5. The process of electroplating and chemical plating has the problem of serious pollution to the environment
6. The cost of the product is relatively high for the production process of electroless plating and electroplating

Embodiment

[0026] A Firstly, take the nylon fabric with the total fiber fineness of 68D, the braid density of 230T, the braid width of 1200mm, and the braid length of 200m, and use high-pressure gas to blow and finish the finishing work. B. The following preparations are all completed in a vacuum environment with a vacuum degree of 4×10 -4 Pa, then use the electric hoist to hang the substrate in the unwinding chamber of the vacuum equipment, clean it through the ion cleaner, and pass through the guide roller, tension roller, and pressure roller. Before entering the tension roller, it needs to pass through the real-time electronic monitoring probe , to detect the thickness and line speed of the fiber fabric substrate; C, the next pretreatment is to carry out magnetron sputtering in the vacuum chamber to pre-plate the metal layer, and the thickness of the primer is 0.5 μm; D, and then after cooling The roller cools down and enters the metal sputtering coating room 1 for magnetron sputterin...

Abstract

The conductive cloth producing process is one physical vapor deposition process. Continuous fiber fabric is made to pass through a serial technological process inside a vacuum equipment so that single or multiple sputtered metal film is formed on th fabric. The said process can producing conductive cloth with metal layer bonding to fiber fabric firmly continuously and in large scale.

Description

Technical field: [0001] The invention relates to a production and preparation process of conductive cloth of shielding material. Background technique: [0002] Conductive cloth is an EMI shielding material, which is widely used in aerospace, electronics, communication, medical, radar and other fields. Domestic conductive fabric products appeared in the 1980s by using electroless plating or electroplating methods to produce conductive fabrics, but due to the limitations of production technology and performance, mainly referring to problems such as adhesion and system stability, continuous scale-up cannot be achieved Production, also can't meet the use requirement of various electrical equipment. Therefore, at present, many merchants and manufacturers who operate and use EMI materials mostly import EMI products processed and formed by conductive cloth from abroad. Since most of the products have been processed and shaped from abroad, their shapes are limited to square, recta...
