Description
本發明涉及表面塗裝領域,尤其涉及一種能夠形成多種顏色之彩色塗層及採用其之電子產品。 The present invention relates to the field of surface coating, and more particularly to a color coating capable of forming a plurality of colors and an electronic product using the same.
手機、電腦及遊戲機等電子產品之表面通常塗裝成不同顏色,以滿足消費者之對產品之外觀之要求。 The surface of electronic products such as mobile phones, computers and game consoles is usually painted in different colors to meet the consumer's requirements for the appearance of the product.
先前技術中,不同顏色藉由噴塗不同顏色之油漆形成。請參閱文獻Electrostatic painting of insulating surfaces,Bouguila,N.;Coelho,R.;Navarre,D.;Industry Applications,IEEE Transactions on Volume 29,Issue 4,July-Aug.1993 Page(s):798-801。然而,這些油漆通常含有具有毒性之有機物質,造成環境污染並損害人之身體健康。此外,由於噴塗之油漆與電子產品基體附著力不強,電子產品於日常使用過程中,難免對其表面產生刮擦,被刮擦部分之噴塗油漆脫落,從而使得電子產品之外觀變得醜陋。 In the prior art, different colors were formed by spraying paint of different colors. See Electrostatic painting of insulating surfaces, Bougila, N.; Coelho, R.; Navarre, D.; Industry Applications, IEEE Transactions on Volume 29, Issue 4, July-Aug. 1993 Page(s): 798-801. However, these paints usually contain toxic organic substances that cause environmental pollution and impair human health. In addition, since the adhesion of the painted paint to the substrate of the electronic product is not strong, in the daily use of the electronic product, it is inevitable that the surface of the paint is scratched, and the sprayed paint of the scraped portion is peeled off, thereby making the appearance of the electronic product ugly.
有鑑於此,有必要提供一種彩色塗層,其不對環境造成污染且對人體無害,並不易於脫落。 In view of this, it is necessary to provide a color coating which is not pollute to the environment and is harmless to the human body and is not easily peeled off.

The reflective layer is made of aluminum for reflecting part of the incident light to form a first reflected light, and the surface of the substrate reflects the remaining incident light to form a second reflected light. The material of the control layer is ceria, which is used to control the optical path difference between the first reflected light and the second reflected light to interfere with the first reflected light and the second incident light, so that the colored coating exhibits different colors.

下面結合附圖及實施例對本技術方案提供之彩色塗層及其製作方法作進一步說明。 The color coating provided by the technical solution and the manufacturing method thereof will be further described below with reference to the accompanying drawings and embodiments.
請參閱圖1,本技術方案第一施例提供之彩色塗層100包括依次堆疊之附著 層120、顏色控制層130、反射層140及耐腐蝕層150。 Referring to FIG. 1 , the color coating 100 provided by the first embodiment of the technical solution includes the adhesion of the stacked layers. Layer 120, color control layer 130, reflective layer 140, and corrosion resistant layer 150.
彩色塗層100形成於基體110之外表面上。基體110可為各種待於外表面形成色彩之產品,如各種電子產品之外殼,基體110可由各種材料製成,如玻璃、金屬、陶瓷、合金、玻璃陶瓷及塑膠等。該塑膠可為聚碳酸酯或聚甲基丙烯酸甲酯等。 A color coating 100 is formed on the outer surface of the substrate 110. The substrate 110 can be a variety of products to be colored on the outer surface, such as the outer casing of various electronic products. The substrate 110 can be made of various materials such as glass, metal, ceramics, alloys, glass ceramics and plastics. The plastic may be polycarbonate or polymethyl methacrylate.
附著層120之材質為金屬鉻,附著層120之厚度為0.3至10奈米,優選為0.3至1.0奈米,本實施例中,附著層120之厚度為0.5奈米。該附著層120可藉由液相沈積法或物理氣相沈積法形成。附著層120能夠增強後續鍍層與基體110之附著度。附著層120厚度小,光線傳播至附著層120時,入射光線發生反射幾率很小,即,可認為附著層120不反射入射光線。 The material of the adhesion layer 120 is metal chromium, and the thickness of the adhesion layer 120 is 0.3 to 10 nm, preferably 0.3 to 1.0 nm. In the present embodiment, the thickness of the adhesion layer 120 is 0.5 nm. The adhesion layer 120 can be formed by a liquid phase deposition method or a physical vapor deposition method. The adhesion layer 120 can enhance the adhesion of the subsequent plating layer to the substrate 110. The thickness of the adhesion layer 120 is small, and when the light propagates to the adhesion layer 120, the incidence of incident light rays is small, that is, the adhesion layer 120 is considered not to reflect the incident light.
顏色控制層130可藉由濺射法、電漿化學氣相沈積法或化學液相沈積法形成於附著層120上。顏色控制層130之材質為二氧化矽,其厚度為50至1000奈米。例如,其可為131奈米、188奈米、206奈米、431奈米或518奈米。顏色控制層130用於藉由控制其厚度從而控制彩色塗層100之顏色。 The color control layer 130 may be formed on the adhesion layer 120 by a sputtering method, a plasma chemical vapor deposition method, or a chemical liquid deposition method. The color control layer 130 is made of cerium oxide and has a thickness of 50 to 1000 nm. For example, it can be 131 nm, 188 nm, 206 nm, 431 nm or 518 nm. The color control layer 130 is used to control the color of the color coat layer 100 by controlling its thickness.
反射層140形成於顏色控制層130上,反射層140之材質為金屬鋁,因為鋁膜具有高反射性,而且易於藉由蒸鍍形成。反射層140之厚度為20至200奈米,優選為50奈米。反射層140可藉由真空蒸鍍形成。反射層140具有反射作用係因為金屬原子中之外層電子(自由電子)並未被原子核束縛,當金屬被入射光線照射時,自由電子吸收了光線之能量,而產生相同頻率之振盪,此振盪又放出與原來光線相同頻率之光線,即,產生反射光纖,此種電子振盪隨著金屬深度之增加而減小。使電子振盪之振幅減小到原來振幅1/e(e為自然對數)時金屬之厚度,稱為該金屬之穿透厚度。因此,當反射層140之厚度小於鋁之穿透厚度時,照射到反射層140之光線部分被反射,其餘部分則可穿透反射層140。 The reflective layer 140 is formed on the color control layer 130. The material of the reflective layer 140 is metallic aluminum because the aluminum film has high reflectivity and is easily formed by evaporation. The reflective layer 140 has a thickness of 20 to 200 nm, preferably 50 nm. The reflective layer 140 can be formed by vacuum evaporation. The reflective layer 140 has a reflection function because the outer layer electrons (free electrons) in the metal atoms are not bound by the nucleus. When the metal is irradiated by the incident light, the free electrons absorb the energy of the light, and the oscillation of the same frequency is generated. Light is emitted at the same frequency as the original light, i.e., a reflective fiber is produced, which decreases as the depth of the metal increases. The thickness of the metal when the amplitude of the electronic oscillation is reduced to the original amplitude 1/e (e is the natural logarithm) is called the penetration thickness of the metal. Therefore, when the thickness of the reflective layer 140 is less than the penetration thickness of the aluminum, the portion of the light that is incident on the reflective layer 140 is reflected, and the remaining portion is transparent to the reflective layer 140.
抗腐蝕層150形成於反射層140上,抗腐蝕層150之材質為金屬鉻。抗腐蝕層150之厚度為可根據實際需要確定,優選為10奈米至100奈米。本技術方案中,抗腐蝕層150之厚度為10奈米。該抗腐蝕層150可藉由液相沈積法或物理氣相沈積法形成。抗腐蝕層150之厚度亦較小,因此入射光線經過抗腐蝕層150時發生反射幾率亦很小。 The anti-corrosion layer 150 is formed on the reflective layer 140, and the anti-corrosion layer 150 is made of metallic chromium. The thickness of the anti-corrosion layer 150 can be determined according to actual needs, and is preferably from 10 nm to 100 nm. In the technical solution, the thickness of the anti-corrosion layer 150 is 10 nm. The anti-corrosion layer 150 can be formed by a liquid deposition method or a physical vapor deposition method. The thickness of the anti-corrosion layer 150 is also small, so that the incidence of incident light rays passing through the anti-corrosion layer 150 is also small.
入射光線照射到彩色塗層100時,先藉由抗腐蝕層150入射到反射層140,部分入射光線被反射,形成第一反射光線L1。其他入射光線藉由反射層140射入顏色控制層130及附著層120,到達基體110之表面時,其他入射光線被表面反射,從而形成第二反射光線L2。第一反射光線L1與第二反射光線L2將發生干涉,當第一反射光線L1與第二反射光線L2之間之光程差滿足某種顏色光波波長之一半之倍數之條件時,就會產生某種顏色之光波震動之增強或減弱,從而觀察彩色塗層100時就呈現彩色。因為顏色控制層130之厚度不同,反射後之光線L1與L2之光程差亦不同,從而,彩色塗層100將會根據顏色控制層130之厚度不同呈現不同之顏色。例如,於附著層120之厚度為0.5奈米,反射層130之厚度為50奈米,抗腐蝕層150之厚度為10奈米之情況下,當顏色控制層130之厚度為131奈米時,彩色塗層100之顏色為藍色;當顏色控制層130之厚度為188奈米時,彩色塗層100之顏色為黃色;當顏色控制層130之厚度為206奈米時,彩色塗層100之顏色為橙色;當顏色控制層130之厚度為431奈米時,彩色塗層100之顏色為紫色;當顏色控制層130之厚度為518奈米時,彩色塗層100之顏色為綠色。因此,對應於不同之顏色控制層130之厚度,將呈現不同之顏色。 When the incident light is irradiated onto the color coating 100, the anti-corrosion layer 150 is first incident on the reflective layer 140, and part of the incident light is reflected to form the first reflected light L1. The other incident light rays are incident on the color control layer 130 and the adhesion layer 120 through the reflective layer 140, and when the surface of the substrate 110 is reached, the other incident light rays are reflected by the surface, thereby forming the second reflected light L2. The first reflected light L1 and the second reflected light L2 will interfere, and when the optical path difference between the first reflected light L1 and the second reflected light L2 satisfies a condition that is a multiple of one-half the wavelength of a certain color light wave, The light wave vibration of a certain color is increased or decreased, so that the color coating 100 is colored when viewed. Because the thickness of the color control layer 130 is different, the optical path difference of the reflected light rays L1 and L2 is also different, and thus, the color coating layer 100 will exhibit different colors according to the thickness of the color control layer 130. For example, when the thickness of the adhesion layer 120 is 0.5 nm, the thickness of the reflection layer 130 is 50 nm, and the thickness of the anti-corrosion layer 150 is 10 nm, when the thickness of the color control layer 130 is 131 nm, The color of the color coating 100 is blue; when the thickness of the color control layer 130 is 188 nm, the color of the color coating 100 is yellow; when the thickness of the color control layer 130 is 206 nm, the color coating 100 The color is orange; when the thickness of the color control layer 130 is 431 nm, the color of the color coating 100 is purple; when the thickness of the color control layer 130 is 518 nm, the color of the color coating 100 is green. Therefore, different colors will be presented corresponding to the thickness of the different color control layer 130.
本技術方案第二實施例提供之彩色塗層200,其結構與本技術方案第一實施例提供之彩色塗層100類似,不同之處在於彩色塗層200包括兩個相互連接之第一彩色區域210與第二彩色區域220,第一彩色區域210包括依次堆疊 之第一附著層211、第一顏色控制層212、第一反射層213及第一耐腐蝕層214,第二彩色區域220包括依次堆疊之第二附著層221、第二顏色控制層222、第二反射層223及第二耐腐蝕層224。惟,第一顏色控制層212與第二顏色控制層222之厚度不同,如此第一彩色區域210與第二彩色區域220呈現不同之顏色。例如,該第一附著層211之厚度與第二附著層221之厚度均為0.5奈米,該第一反射層212之厚度與第二反射層222之厚度均為50奈米,該第一抗腐蝕層214之厚度與第二抗腐蝕層224之厚度均為10奈米。第一彩色塗層區域210之第一顏色控制層212之厚度為131奈米,第二彩色塗層區域220之第二顏色控制層222之厚度為188奈米,第一彩色塗層區域210呈現藍色,第二彩色塗層區域220呈現黃色,因而,彩色塗層結構200將呈現為黃色與藍色相連接之圖案。 The second embodiment of the present invention provides a color coating 200 having a structure similar to that of the color coating 100 provided by the first embodiment of the present technology, except that the color coating 200 includes two first color regions connected to each other. 210 and the second color area 220, the first color area 210 includes sequentially stacked a first adhesion layer 211, a first color control layer 212, a first reflective layer 213, and a first corrosion-resistant layer 214. The second color region 220 includes a second adhesion layer 221, a second color control layer 222, and a second layer. The second reflective layer 223 and the second corrosion resistant layer 224. However, the thickness of the first color control layer 212 and the second color control layer 222 are different, such that the first color region 210 and the second color region 220 exhibit different colors. For example, the thickness of the first adhesion layer 211 and the thickness of the second adhesion layer 221 are both 0.5 nm, and the thickness of the first reflective layer 212 and the thickness of the second reflective layer 222 are both 50 nm. The thickness of the corrosion layer 214 and the thickness of the second corrosion resistant layer 224 are both 10 nm. The thickness of the first color control layer 212 of the first color coating region 210 is 131 nm, and the thickness of the second color control layer 222 of the second color coating region 220 is 188 nm, and the first color coating region 210 is presented. Blue, the second colored coating region 220 appears yellow, and thus, the colored coating structure 200 will assume a pattern of yellow and blue connections.
