[0003] Therefore, in order to prevent computer users from using the computer for a long time and being exposed to the environment of high electromagnetic waves, the computer manufacturer arranges a plurality of metal sheets on the inner edge of the plastic casing of the computer, and connects these metal sheets to a grounding terminal, so that When the computer is in use, the electromagnetic waves generated by it can be introduced into the ground terminal through the metal sheets and absorbed by the ground terminal. The inside of the plastic shell not only increases the weight of the computer, but also due to the stamping and bending manufacturing process of the sheet metal, the metal sheet shields have too many holes and cracks, which is not ideal for the electromagnetic wave shielding effect, and the construction is complicated. will increase production costs

Embodiment Construction
[0017] Specific embodiments of the present invention are described below in conjunction with accompanying drawing:
[0018] A treatment method of the electromagnetic wave isolation function on the surface of a plastic material of the present invention, please refer to figure 1 ,figure 2, image 3 As shown, in this method, a metal-friendly polymer primer 12(1) is coated on the surface of a plastic casing 11 of an electronic device by spraying paint, and then, after the primer 12 is dry, the The surface of the primer 12 is coated with a layer of metal film 13(2) as a guide for radio waves by low-temperature vacuum coating, and then coated with a layer of metal film 13(2) as a surface for anti-oxidation and guiding magnetic waves by the same low-temperature vacuum coating. The metal film 14 (3) and finally the finished product (4).
[0019] Through the sealing effect of the metal-friendly polymer primer 12, a film that strengthens the plastic surface of the casing 11 can be obt...

The invention discloses a method for processing the electromagnetic wave isolation function of a plastic material surface. The surface of a plastic casing of an electronic device is coated with metal philic macromolecular polymer priming by spray painting; then, after the priming is dry, the surface of the priming is plated with a metallic film used for guiding electric wave by low-temperature vacuum filming; and subsequently, a surface metallic film used as surface capable of antioxidation and guiding magnetic wave is plated by the low-temperature vacuum filming. The electromagnetic wave interface (EMI) caused by the electronic device can be shielded in the casing by the hole-sealing function of the metal philic macromolecular polymer priming, so as to avoid the electromagnetic wave leaking to injure human body; and the antioxidant surface metallic film protects the metallic film to ensure that the metallic film does not rust and lose the efficiency of guiding the electromagnetic wave.
Description
technical field [0001] The invention relates to a treatment method for the electromagnetic wave isolation function on the surface of a plastic material, in particular to a method for plating a multi-layer coating film as an electromagnetic wave isolation function on the surface of a plastic material. Background technique [0002] The electrical appliances used in daily life on the market, such as: computers, mobile phones, wireless phones, motors and transformers, when they are used, emit harmful electromagnetic waves (electromagnetic waves), wherein the electromagnetic waves are driven by an electric field (electric A physical phenomenon in which a field) interacts perpendicularly with a magnetic field. If the human body is exposed to a high electromagnetic wave environment for a long time, it will cause damage to the deoxyribonucleic acid (DNA) molecules of the cells, and accelerate the proliferation of cancer cells, turning them into malignant tumors (such as leukemia, br...
