Abstract
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
The present invention relates to a kind of treatment process of electromagnetic wave isolation function of plastic material surface, particularly relate to a kind of method of establishing of on plastic material surface, plating as the multicoating of electromagnetic wave isolation function.
Background technology
Daily on the market applied electrical appliance, such as: computer, mobil phone, wireless telephony, motor and transformer, it is when being used, give out the hertzian wave (electromagnetic wave) of harmful human body virtually, wherein this hertzian wave is by the vertical interactive a kind of physical phenomenon with a magnetic field of an electric field (electric field).Human body can cause that the thymus nucleic acid (DNA) of cell divides the quantum splitting infringement, and quicken the competence for added value of cancer cells if be exposed in the high electromagnetic environment for a long time, be changed to malignant tumour (as: leukemia, brain tumor ... Deng).
Therefore, computer maker uses a computer for a long time for exempting the computer user, and be exposed in the high electromagnetic environment, at computer plastic casing inner edge a plurality of tinsels are set, and these tinsels are connected with a ground terminal, when this computer is used, the hertzian wave that it produced can import this ground terminal via these tinsels, and absorbed by this ground terminal, yet these tinsels mostly are the tinplate material, bending is shaped through panel beating, lock is overlying on plastic casing inside, and computer weight is increased, and because the manufacturing processed of the punching press bending of panel beating, make that the broken hole crack of these tinsel masks is too much, unsatisfactory to electromagnetic shielding effect, add that construction is complicated, production cost is improved.
Summary of the invention
The objective of the invention is to, a kind of treatment process of electromagnetic wave isolation function of plastic material surface is provided, on plastic material surface, to plate the multicoating of establishing as electromagnetic wave isolation function, solve traditional electromagnetic wave screening structure in the aforementioned prior art, unclear to electromagnetic shielding effect, and the complicated disappearance of construction.
The present invention adopts following technique means to realize:
A kind of treatment process of electromagnetic wave isolation function of plastic material surface, it is characterized in that: on the cabinet surface of an electronic installation, be coated with the high molecular polymer priming paint of one deck parent metal in the mode of spraying paint, then, by the time after this priming paint drying, plating the metallic membrane that one deck is used as the guiding electric wave in this priming paint surface in cryogenic vacuum plated film mode again, then, plating one deck in identical cryogenic vacuum plated film mode again and having the metal film on surface that the guiding magnetic wave is used concurrently as surface oxidation-resistant.
Aforesaid method can be utilized the priming paint convection drying of dryer with the cabinet coating.
The metallic membrane of described guiding electric wave is the copper metallic membrane.
The metallic membrane of aforesaid guiding electric wave is for improving the copper zinc alloy metallic membrane or the X alloy metallic membrane of opposing environmental attack function.
The metal film on surface of aforesaid guiding magnetic wave is the iron-nickel-chromium metallic membrane.
The metal film on surface of aforesaid guiding magnetic wave is for improving the iron nickel metal film of guiding magnetic wave usefulness.
The present invention compared with prior art has following remarkable advantages and beneficial effect:
According to above-mentioned purpose, this method is on the cabinet surface of an electronic installation, be coated with the high molecular polymer priming paint of one deck parent metal in the mode of spraying paint, then, by the time after this priming paint drying, plating the metallic membrane that one deck is used as the guiding electric wave in this priming paint surface in cryogenic vacuum plated film mode again, then, plating one deck in identical cryogenic vacuum plated film mode again and having the metal film on surface that the guiding magnetic wave is used concurrently as surface oxidation-resistant; So; sealing of hole effect by close metal-polymer polymkeric substance priming paint; the film of casing frosting can be strengthened; and the sticking power of increase metal level; simultaneously the electromagnetic wave shielding of the big area ground connection that constitutes of the metallic membrane of guide electromagnetic waves, metal film on surface can be shielded from the Electromagnetic Interference that electronic installation produced in the casing, to avoid the hertzian wave injury human body that leaks; and, make unlikely getting rusty and lose the usefulness of guide electromagnetic waves by oxidation resistant metal film on surface protection metallic membrane.
