Description

201018738 IX. Description of the Invention: [Technical Field] The present invention is a multilayer composite film film, in particular, a method of manufacturing a multilayer composite film capable of holding metal particles in a discontinuous phase to avoid radio wave shielding effects. [Prior Art]

NCVM, also known as discontinuous vacuum metallization or non-conductive vacuum metallization, is a new high-tech technology that originates from ordinary vacuum coating. Vacuum metallization (VM) refers to the organic conversion of metal materials under vacuum conditions using specific means such as chemistry and physics to convert metal into constituent particles, deposited or adsorbed on the surface of plastic or metal materials. Forming a metal film, which is what we call a coating. The processing technology of NCVM is higher than that of the general VM, and the processing process is much more complicated than the ordinary process. Referring to the first figure, the NCVM technology converts the mineral film into metal ions in a vacuum chamber to make the metal material (4), (10) adhere (de-plating) or evaporate (evaporate) to the object to be plated. Surface, forming a non-conductive vacuum metal rhodium (10), due to discontinuous deposition of metal molecular particles (for example) using the discontinuous nature of the phases, the coating (10) has non-electrical characteristics ' Because it is a discontinuous phase deposited between 'metal particles (1)) 盥 = genus particles (1)) allows light to pass through. ^ = can be applied to a variety of substrates (such as mobile phone panels) as a decoration, which is tied to a non-conductive vacuum metal film (10) to add a texture 'and the conductivity of the coating (10) Poor performance and even insulation, so it can produce 201018738 products with metallic luster, light transmission and does not affect communication functions. Vacuum metal coating technology is a functional appearance finishing technology, and an alloy coating has excellent wear resistance, corrosion resistance, uniformity of coating thickness, and compactness. It has been widely used in electronic products. With the rapid development of the electronics industry, the requirements for coating technology are getting higher and higher, and the development of new technologies, new products, and new processes is endless. At present, in international electronic communication companies, communication products such as M〇toro|a, SONY ERICSSON and NOKIA have been introduced into ❹NCVM film processing. Domestic companies, such as HTC, Taiwan's international aviation (Garmin), and Shenji (Mi〇)'s own brand system vendors, have also introduced their communication products into the NCVM mineral film process, resulting in some domestic OEM Enterprises have invested in research and development of NCV technology. In Taiwan, there are speed, Zhengyi, Qihui, Yahan, etc. In the mainland, there are Foxconn, Gujing, Green Point, Yongye and other companies, which can not carry out Bluetooth headsets and mobile phone casings. Conductive vacuum film processing, or provide a variety of color key film and non-conductive mineral film of enamel, PC, ABS plastic and other materials. • NCVM technology stands out from the field of surface coating and coating vacuum coating technology with its special non-conductivity, metal texture and excellent physical properties and weather resistance. It has become the key technology of 3C enterprises in electronic communication products, and is a plastic material. Surface metal coatings deliver new value. Moreover, NCVM technology does not use nickel and cadmium in the hexavalent chromium and coating layers used in the general coating process, so it does not pose any harm to the human body and solves the problem of environmental pollution. Although the overall process technology of NCVM technology is still incomplete and mature, its product value is high, the market potential is large, and the profit margin is still large. 5 201018738 has gradually replaced the traditional coating industry, and is called the mainstream plastic product surface treatment technology. And can be expected to bring significant economic and social benefits to the company* Qiao tea and society. Please refer to the second panel, the existing panel processing system: obtain a substrate (usually a plastic product), and then ultrasonically clean and then dry; apply a primer to the substrate (10) One of the surfaces, and make and purple

External light,) and thermal curing (thermal curin_ ^ curing to become a primer (12) (please refer to the third a picture); then the undercoat (12) is sputtered or evaporated to form a Ncvm mineral film (14) (please refer to 帛3 b Η), that is, the base coating (12) is provided with a plurality of spaced metal particles; and the NCVM coating (14) is sequentially coated with the intermediate coating a coating agent and a top coating agent to cover the above metal particles and fill the gap between the metal particles, and then cure the intermediate coating agent and the top coating agent into a medium coating layer by ultraviolet light (UV) and heat curing (therma| _叩). (16) and topcoat (18) (please refer to Figure 3C for details) to obtain a coated panel, and the resulting panel has a metallic appearance and does not affect the radio frequency (RF) of wireless communication. The effect of transmission. Regarding the above coating, the primary feature is non-conductivity to meet the normal use of wireless communication products; secondly, to ensure "metal texture" to achieve important appearance requirements; finally by intermediate coating / top coating and coating Combined, it can guarantee the physical properties and weather resistance of the product. In order to meet the needs of customers, NCVM can be applied to various plastic materials in addition to metal materials. 201018738 Decorative coatings, such as PC, PC+ABS, ABS, P_A, NYL^N, engineering plastics, etc. Compliant with the green environmental requirements of process technology, it is an alternative technology for non-chrome (Non-Chrome) coated products, suitable for all plastic products in the surface, especially for 3c products with signal transmission and reception 'especially in the antenna Near the area of the cover, such as mobile phones (m〇bj|e卟〇), personal digital assistant (PDA), smart electricity # (smart ph〇ne), GPS satellite navigation, Bluetooth headset, etc. The main feature of NCVM 1 is the knot. Person p &

僳疋,,Ή D The characteristics of the traditional vacuum coating technology, using new coating technology, new materials, to make the metal appearance of different colors of the general vacuum coating 'to achieve the function of the surface of the cosmetic. Finished products made with NCVM technology can be tested by high voltage tens of thousands of volts of high voltage test 'not conducting or not being broken down. Because of its non-conductivity, when the mobile phone or Bluetooth headset receives or transmits a signal, the generated electromagnetic field is not accumulated by the conductive coating, and thus does not affect the radio frequency (rf) performance of the mobile phone and the electrostatic discharge (ESDH). "Energy" means that wireless products can achieve better communication results, and because NCVM does not affect the transmission of rf, the transmission power can be adjusted to be lower than the power required in the past for the shovel process. 'This makes it possible to make the communication time of the battery of the communication product longer. 'The battery life is longer.' The communication is more no noise, and it will not affect the human body. From the electrical performance (four) degree, the coating can pass the conduction interference test. As for the vacuum coating itself, it can simultaneously protect/physical and weathering tests, such as adhesion, abrasion resistance, alcohol resistance, liquid, high temperature and high humidity testing, etc. When the casing of the communication product is processed, The antenna module of the product does not need to be designed to be grounded to the machine 7 201018738 board, which saves the test on the antenna module and saves cost. The appearance of the product is stronger than the metal texture of the product. , thereby increasing the technical content of the product' to increase the added value of the product.

In addition, NCVM gives the substrate (plastic) a metallic luster texture, and at the same time, it can achieve semi-transparency control. (4) It also reflects the metal f sense and also has light penetrability, which is the characteristic that metal materials cannot display. Bu Ruo's product casing adopts S NCVM material, which can make the design of the product more versatile and brighter and more colorful by using the characteristics of light transmission or semi-light transmission. In the above process, the NCVM process is to vacuum the substrate to be smashed into the vacuum chamber, and then evacuate the light material to be filmed by gas (sputtering) Or heating evaporation (evaporation), the metal particles on the wire adhere to the substrate. The molecular particles between the metal materials that are plated or vapor-deposited onto the substrate must be left so that they do not form a single metal film that conducts electricity to give a metallic luster without metal. Radio wave shadowing effect. In the Μ process, the time and thickness control of the film is the key to the success of its electrical debugging. However, please refer to the fourth figure, when the metal is rough (the original should be the deposition of the discontinuous phase, but due to deposition The time is not easy to control the right / child accumulation time is too long, it will lead to the distribution of the continuous phase of the mineral film, so the NCVM coating, (), although still the film's appearance has metallic luster, also has light transmission, but the pot fee _ , , electrical is turned on 'that is electrically conductive , electrical test can not meet the electrical requirements of JVJ C Μ > β , _ , this is the current industry 's private bottleneck ; The ηη product time is too short 'the metal coating thickness is not enough, and can not show the metal 夯 Pan 0 m I丨|^ The time of this deposition can not control the cause of the film 201018738 film success rate decline. Again =, the existing NCVM process Most of them use tin (Sn) M (), or tin-steel wire as the NCVM process == use!: The low conductivity of copper itself to avoid the above-mentioned electricity, benevolence, although tin, indium Has the advantage of low conductivity, but it is presented Metallic luster color warm - Ze selectively small, even in the relatively dull twenty-two Therefore, when a metal plating film to light I, coating thickness reaches a certain thickness

: When it has the advantage of low conductivity, it is often broken down and turned on. This causes process instability and yield loss.

The principle of the present invention is deposited in the NCVM coating process. When the metal particles are still in the discontinuous phase, regardless of the amount of time, the NCVM coating action of the metal target can be stopped, and then an insulating non-metal film is formed, that is, on the metal particles of the discontinuous phase, and then non-formed. a metal insulating material, and the non-metallic insulating material is on the metal particles or between the metal particles 12 201018738 particles to ensure their electrical non-conductivity, so that the metal particles even after the _ segment Time After that, there is still no possibility of mutual contact and conduction.

The target used in the present invention It can be a highly conductive metal such as gold, silver, copper, #g, etc., instead of using only low conductivity indium or tin, so that a variety of rich metallic luster substrates can be produced. Moreover, because the earth's reserves of copper and aluminum are much larger than the reserves of tin and indium, and the color temperature of the metallic luster is cold, the gloss is bright, and the metal coating is more effective in the surface coating effect of the substrate. Tin and indium are strong and popular with consumers. 3. Moreover, the existing NCVM process is limited by the shortage and limitation of process equipment, and the weak process capability, and can only rely on the low conductivity of palladium. Sexuality, manufacturing an electronic communication product appearance coating that barely meets the basic specifications, but the invention improves the processing capability of the communication product for the NCVM coating and the average production yield of the industry, and satisfies the higher quality and diversity of the consumer. Select, can develop an internationally competitive NCVM coating technology, high product value" 13 201018738 [Embodiment],: see the five maps, the present invention provides a multilayer composite coating manufacturing '', but It is not intended to limit the scope of the invention, and the method includes a pretreatment step, a discontinuous phase metal ore layer formation step, a "surface layer formation step" and a post-treatment step. The pre-processing steps include: using an injection technique to provide a substrate, and most of the plastic-injected materials are hot-hardened or thermally cross-linked (therma丨(eight) polymer, the system is based on heat The plastic hardening method of the catalyst, that is, when the temperature reaches a certain degree/dish degree, the bridging agent in the injection material starts to react, so that: ": sub-key, 'truss bridge, when the temperature is cooled down, the cross-linking is completed. Molding, but plastic injection for the convenience of molding, usually added or more or V helper or release agent, these additives or release agents do not participate in the cross-linking reaction 'and hardened after filling in the polymerization molecule In the meantime, most of the (four) cross-linking reactions (ie hardening) can not be achieved, "00% cross-linking, so there will be some plastic raw materials without cross-linking polymerization hardening; said that because the injection molding is completed after the 'substrate surface More or less residual auxiliaries, release agents and uncrosslinked hardened plastic materials, in order to avoid residual impurities on the surface of the substrate, which may affect the progress of the post-process or cause the primer to not adhere to it. Coating peeling Therefore, the substrate is cleaned by an ultrasonic cleaning device; as shown in the fifth drawing, after the surface of one of the substrates (2〇) forms an undercoat layer (21), which is coated. The main purpose of the layer (21) setting is to make the metallized particles of the NCVM coating to be followed by the strength of the substrate of the plastic injection 14 201018738, and to repair the surface of the substrate (20) (potholes, unevenness). The NCVM can be coated to give a smooth shiny surface; please refer to Figure 5B to transport the substrate (2〇) into the vacuum chamber to ensure metal particles and undercoat before NCVM coating ( 21) If the month b is only followed, a vacuum plasma cleaning step may be performed, which includes vacuuming the environment to remove moisture from the residual solvent, and bombarding the undercoat with a gas knife (30) of the plasma (21) The surface is used to clean the contaminated oil/shell on the surface of the undercoat layer (21) and to increase the surface roughening effect of the undercoat layer (21) to facilitate the adhesion of the metal particles to the undercoat layer (21). The step of forming the discontinuous phase metallization layer, please refer to the fifth C diagram Forming a plurality of spaced apart metal particles (221) by the NCVM coating technique on the undercoat layer (21) to obtain a discontinuous phase metallization layer (22), and the metal particles (221) are still The coating process is stopped when the discontinuous phase is in. The surface layer forming step includes: Referring to FIG. 5D, an insulating non-metal film forming step is performed on the metal particles (221) by NCVM coating technology. An insulating non-metal film (23) is formed thereon; as shown in FIG. E, an additional discontinuous phase metal film formation step is performed, which is attached to the insulating non-metal film (23) to ncvm The coating technique forms a plurality of spaced apart metal particles (241) to obtain another additional discontinuous phase metal plating layer (24), wherein the multilayer composite coating film is obtained; wherein the insulating non-metal film forming step and the additional discontinuity The phase forming step of the metal plating layer can be repeated once or several times, and the number of repetitions is 15 201018738 : according to the thickness and metal required to be achieved, and can determine the first transmittance required for the kilogram and the film is not attached. The surface of the phase metal* film is an insulating non-metal layer complex~ film: If film layer 'is demonstrated in this embodiment of the multilayer layer::: the surface is an additional discontinuous phase metal money layer: March see fifth FFig. t ^ m ή χ ^ ^ No, after that, the n〇vm coating technique is applied to the additional discontinuous phase metal plating film (23a); and the layer (24) is wire-insulated with insulating non-gold.

7 G is not in the insulating non-metallic film (23a) two, the film technology forms a plurality of spaced apart metal particles a to obtain another additional discontinuous phase metal forging layer (24 sentences; Referring to the fifth and the figure, this embodiment demonstrates repeating the above steps to form a four-layer insulating non-metal film (23, coffee, coffee, 23 〇 and additional discontinuous phase metallization layer (24, 24a, 24b). , 24c). Because in this process, the metal coating layer (24, 24a, 24b, 24c) is always kept in the discontinuous phase, so it is impossible to conduct electricity, ensuring the current industry's requirements for its non-conductivity. X NCVM forging The film technology forms the insulating non-metal film (Μ, 23a, 23c). The coating film should be a discontinuous phase composed of a plurality of insulating non-metallic particles, but the amount of insulating non-metallic particles after a period of coating time. More and more, and the density is getting higher and higher, and a continuous phase is formed at this time. Therefore, the insulating non-metal film layer (23, 23a, 23b, 23c) can be in a continuous phase to ensure that it is below or even above it. The metal particles maintain a discontinuous phase. But the best is discontinuous It can not only shield the metal particles, but also minimize the processing time of the NCVM coating to obtain a maximum yield of 16 201018738 per unit time, and save material costs. The post-processing steps include: As shown in the figure, the additional discontinuous phase metal coating layer (24c) disposed on the outermost layer can be coated with a layer of intermediate coating agent and cured by ultraviolet light (UV) and thermoma curing. - the intermediate coating (25); or as shown in the seventh figure, the additional discontinuous phase metal coating layer (24c) disposed on the outermost layer can be coated with a layer of coating agent and made ultraviolet (UV) And curing with a thermal curing effect to become a topcoat (26); or as shown in the eighth figure, the additional discontinuous phase metallization layer (24c) disposed above the outermost layer can be first Coating a layer of intermediate coating agent and curing it by ultraviolet light (UV) and thermal curing to form a medium coating layer (25·), and then applying a layer coating agent on the medium coating layer, and It is cured by ultraviolet light (UV) and heat (therm a丨curing) solidifies to form a coating (26·).

Because some topcoats and the additional (four) phase metal 35 film layer have poor adhesion, the middle coating (25·) is needed to strengthen, or some aspects are added to the middle coating agent to enrich the consumer. Optional. Because the topcoat is required to have special specifications such as scratch resistance, anti-fouling and anti-fingerprint, it is one of the most important aspects of appearance. , wear resistance, high hardness, even the setting of this * surface coating is a communication product =, in the Lang Li non-metal film shape, can be placed in the discontinuous phase of the metal particles (221) In a gas or helium environment, 17 201018738 metal particles (221) surface formed a nitride layer or oxide layer, resulting in insulation effect.
