As the surface of the product is activated and cleaned before film coating, and the technical parameter of evaporation coating of an NCVM film is optimized, the adhesion property of the NCVM film on the product is greatly improved, and the film is endowed with the characteristics of abrasion resistance, alcohol resistance, human sweat resistance, high-temperature and high-humidity storage, and the like.
Description
Technical field
The present invention relates to a kind of technical field of vacuum plating, be specifically related to a kind of film coating method of NCVM film.
Background technology
Electroplating technology is as a kind of function finish technology, and its alloy layer has characteristics such as excellent abrasive, solidity to corrosion, thickness of coating homogeneity, density height, in electronic product, has obtained to widely apply.Along with the fast development of electronic industry, to electroplating technology require increasingly highly, new technology, product innovation, novel process emerge in an endless stream.NCVM claims discontinuous coating technique or non-conductive electroplating technology again, is a kind of the galvanized new and high technology of edge conventional vacuum.Vacuum plating is called for short VM, is the abbreviation of vacuum metallization.It is meant metallic substance under vacuum condition, and limited meanses such as utilization chemistry, physics carry out organic conversion, make metal convert particle to, deposit or be adsorbed on the surface of plastic material, formation film, just our so-called plated film.NCVM is claimed in the non-conductive plating of vacuum again, is the abbreviation of English Non conductive vacuum metallization.Its complete processing is higher than conventional vacuum electroplates, and its procedure for processing is much more complicated than common processing procedure.
NCVM adopts to plate out films such as metal and insulating compound, utilizes each mutually discontinuous characteristic, obtains the effect that FINAL APPEARANCE has metal-like and do not have influence on wireless communication transmission.At first to realize non-conductively, satisfy the normal use of radio communication product; Its this important appearance requirement of less important assurance " metal-like "; Combine with coatings through UV coating at last, finally guarantee the rerum natura and the weathering resistance of product, meet customer need.NCVM can be applicable to various plastic materials; Like PC, PC+ABS, ABS, PMMA, NYLON, engineering plastics etc., it more meets the environment protection requirement of manufacture craft, is the substitute technology of Chrome-free (Non-Chrome) plated item; Be applicable to that all need surface-treated plastics series products; Be specially adapted to the 3C Product of signal receiving/transmission, especially at the antenna cover near zone, like Mobile Phone, PDA, Smart Phone, gps satellite navigation, blue-tooth earphone etc.The NCVM technology is just shown one's talent in the vacuum plating technical field with its special non-conductive, metal-like and good rerum natura and weathering resistance, robs and towers above the rest; Become 3C enterprise focus technology on the telecommunications product; Realize new value for the plastic material surface coating, its value of the product is high, and market potential is big; Become the plastics series products process for treating surface of main flow with progressively substituting traditional electroplating industry, will bring remarkable economic efficiency and social benefit for enterprise and society.
The integrated artistic of the coating technique of present NCVM is still immature at present, and the NCVM film of being produced, metal are adsorbed on plastic housing surface under the vaporific attitude of atom, be exposed in the air fully; Because the metallic diaphragm of this moment has necessarily " metal reactivity ", therefore in the process of using, can stay fingerprint; When especially running into scratching, be easy to damage the NCVM film, so directly influenced the outward appearance and the performance of its product; Yet in order to solve above-mentioned deficiency, the coating technique of NCVM has been done improvement, increased the UV roasting procedure one; Although performance has improved greatly, outermost no longer be metallic membrane, but hardened paint.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the present invention is to provide the adhesion property of a kind of NCVM of raising film on product so that the film coating method of robust NCVM film.
The technical scheme that the present invention adopted is following:
The film coating method of NCVM film; It is characterized in that: may further comprise the steps: A, activation and clean, carried out activation and clean by the surface of plated product, the treatment time is 60S; Vacuum tightness in the Vakuumkammer reaches 70Pa, and plated film electricity cabinet is 3600V through the voltage that transformation outputs to Vakuumkammer; B, will be put into Vakuumkammer by plated product and steam tin-plated coating film, tinned thickness is not more than 30 nanometers; Wherein, the vacuum tightness in the Vakuumkammer reaches 75Pa, and plated film electricity cabinet is 4000V through the voltage that transformation outputs to Vakuumkammer, and the tinned time is not more than 80S.
Said tin adopts purity at the tin more than 99.99%.
Beneficial effect of the present invention: because before plated film; Activation and clean have been carried out in surface to product; And optimized the technical parameter of vapor deposition NCVM film; Thereby improved the adhesion property of NCVM film on product greatly, made this film have characteristics such as abrasion performance, anti-alcohol, artificial perspiration resistance's liquid, hot and humid storage.
Embodiment
The film coating method of NCVM film; It is characterized in that: may further comprise the steps: A, activation and clean, carried out activation and clean by the surface of plated product, the treatment time is 60S; Vacuum tightness in the Vakuumkammer reaches 70Pa, and plated film electricity cabinet is 3600V through the voltage that transformation outputs to Vakuumkammer; B, will be put into Vakuumkammer by plated product and steam tin-plated coating film, tinned thickness is not more than 30 nanometers; Wherein, the vacuum tightness in the Vakuumkammer reaches 75Pa, and plated film electricity cabinet is 4000V through the voltage that transformation outputs to Vakuumkammer, and the tinned time is not more than 80S.Said tin adopts purity at 99.99% tin.
The NCVM film that the present invention made has following characteristics: owing to adopt above-mentioned technology; The principal character of NCVM is the characteristic that has combined the traditional vacuum coating technique; Adopt new coating technique and changed Coating Materials; Make the metal appearance effect of the galvanized different colours of conventional vacuum, play the function of beautifying workpiece surface.The finished product that adopts the NCVM technology to make can be through the Hi-pot test of several ten thousand volts in high pressure ammeter, not conducting or not breakdown.Exactly because its non-conductive property; When the present invention is used for mobile phone or bluetooth earphone reception or emission signal; The coating that the EM field that produces is not conducted electricity is hoarded, thereby does not influence the radio-frequency performance and the electrostatic discharge performance of mobile phone, that is to say to make wireless product reach better reception effect; No noise more can not produce any influence to human body.From the electrical property angle, it can be through conductive test and electronic jamming test.From vacuum plating itself, it can guarantee normal physics and weather-proof test simultaneously, like sticking power, abrasion performance, anti-alcohol, artificial perspiration resistance's liquid, hot and humid storage etc.When the casing of communication product adopted the NCVM processing procedure, the Anneta module of product did not need to design the loop again and is grounded on the machine plate, can save the detection on Anneta module thus, and saved cost; The outward appearance metal-like of product is stronger simultaneously, and then improves the scientific and technological content of product, increases the value added of product.
The above is a preferred implementation of the present invention, can not limit the present invention's interest field certainly with this.Should be pointed out that for those skilled in the art, technical scheme of the present invention is made amendment or is equal to replacement, do not break away from protection scope of the present invention.
