Problems solved by technology

However, because the treatment of electroplating nickel waste solution is cumbersome, and nickel is a heavy metal, it brings great hidden dangers to the environment and is harmful to human body, and the price of nickel and nickel salt has been high in recent years, so electroplating nickel is used as the copper layer The cost of the protective layer is high, and it is not conducive to environmental protection

Abstract

The invention provides a soft material and the preparation method and use, which precede ion plating or magnetic control sputtering metal plating to the soft material, then precede vacuum metal steaming plating, the produced soft material product has good adhering capability, the resistance value is between 0.03 to 103 Omega, can ensure the vertical electricity conduction to the air permeability textile fabric. Or precede ion plating or magnetic control sputtering metal plating to the soft material, then proceed copper plating, and proceed vacuum steaming plating metal then. The resistance of the produced soft electricity conduction is between 0.005 to 0.03 Omega, the adhesive force is good, the erosion performance is better, the material shielding performance is larger than 70bB. The soft material can be used print the base material of circuit board , shielding clothes and various packaging material.

Description

Technical field: [0001] The invention relates to a flexible material; meanwhile, it relates to a preparation method of the flexible material; in addition, it also relates to an application of the flexible material. Background technique: [0002] Magnetron sputtering plating has the advantages of good adhesion, a wide range of coating types and materials that can be plated, no pollution, and can achieve vertical conductivity for gas-permeable flexible substrates. Ion plating has the advantages of strong adhesion, the coating is not easy to fall off; good diffraction, uniform thickness of the coating; dense coating, less pinhole bubbles; wide range of plating materials, low material consumption, and no pollution. However, the products produced only by magnetron sputtering and ion plating processes have low efficiency, complex equipment and high cost. Compared with magnetron sputtering plating and ion plating, vacuum evaporation has the characteristics of high efficiency and l...
