[Prior Art] With the rapid development of electronic products, the use of portable electronic devices (such as mobile phones, MP3 players, personal digital assistants) has become very common. In order to make the portable electronic device have a good appearance and feel, the portable electronic device often uses a variety of materials for the housing. For example, in order to make the portable electronic device have a metallic appearance, a metal material such as a magnesium alloy or a stainless steel is used as a casing for carrying the electronic device.榼1 tube magnesium alloy, stainless steel and other metal materials have high strength, but the shell will inevitably collide during use, so the shell is still prone to deformation; and since the outer surface of the shell is directly exposed to the air, After a period of use, it is also easy to get hurt, wear and oxygen: squat. Amorphous alloys have structural characteristics similar to glass, and have characteristics of high strength, toughness, good plasticity, corrosion resistance and easy formation of complex structures. Therefore, in order to improve the strength and surface properties of the shell, various products have been made of amorphous alloys. Make the case. However, the appearance of the casing made of an amorphous alloy is single, and it is difficult to meet the demand for the appearance of the portable electronic device; and the amorphous alloy has high hardness and insufficient softness, and the amorphous alloy casing is also likely to be inferior in hand. In order to improve the appearance suitability and hand feeling of the amorphous alloy case, a top coat may be formed by applying a top coat on the surface of the amorphous alloy. However, after the outer covering is used for a period of time, the outer covering itself is prone to fall off and rot, which affects the appearance of the product.

After the topcoat is applied to the adhesive layer 144, the outer cover 146 can be formed by successive steps of leveling, curing, and the like. The curing method may be thermal curing or photocuring. For example, when the topcoat is an ultraviolet curing lacquer, the topcoat is cured by ultraviolet curing. [0019] In the above casing 10, since the adhesive layer 144 is formed between the plating layer 142 and the outer cover 146, the adhesive layer 144 can enhance the bonding force between the key film layer 142 and the outer cover layer 146, thereby preventing or Reducing the outer cover 146 from falling off during use, avoiding damage to the coating layer 142, thereby ensuring a good appearance of the product _4244 (P No. A0101 Page 6 / Total 13 Page 1013004735-0 1360479 '[0020] ' :1 In the present embodiment, the adhesive layer 144 includes a gas-containing polyolefin, and the gas of the gas-containing polyolefin can react with the metal atoms in the coating layer 142 to form a strong force. The chemical bond, and the organic molecular chain in the gas-containing polyolefin can attract the organic molecular chain of the outer cover 146 to form a strong binding force.
^ J 因此黏合層144可使外覆層146與鍍膜層142之結合力增 強，從而防止外覆層146從非晶合金基材12上脫落，避免 或減少鍍膜層142被氧化或腐蝕。並且由於黏合層144係 由聚合物材料組成，其還具有一定之彈性，因此會增加 處於外表面之外覆層146之柔軟度，從而提升殼體10之手 [0021] 另外，於殼體10之表面處理過程中，通過使用不同之靶 材來沈積鍍膜層142或改變面漆之顏色，還易於對殼體10 之顏色進行變東，從而滿足不同之外觀需求。以及採用 絕緣真空鍍膦法形成絕緣鍍膜層142時，絕緣鍍膜層142 可讓電磁信號穿過，因此其不會影響攜帶式電子裝置既 定之射頻（RF)性能與電磁相容（ESD)性能。 [0022] 請參閱圖2，所示為本發明較佳實施方式二之殼體2Q。殼 體20與殼體10相似，包括非晶合金基材22與塗層24。塗 層24包括鍍膜層242、黏合層244及外覆層246，其不同 點在於：塗層24還包括一底層241。底層241形成於非晶 合金基材22之表面，處於非晶合金基材22與鍍膜層242之 間。底層241之厚度可為1微米至30微米。表面處理過程 係先於非晶合金基材22上塗佈底漆，並依次經過流平、 固化等步驟形成底層241，然後再依次於底層241沈積鍍 膜層242，塗佈黏合劑形成黏合層244及塗佈面漆形成外 1013004735-0 第7頁/共13頁 1360479 101年01^ 04日•核正替換ϊ" ' 覆層246。其中底漆之主要成分可為丙烯酸樹脂，固化彳 式可為熱固化或光固化。可以理解，於殼體2〇中由於 存在底層241，因此非晶合金基材22與底層241之相接表 面即使為粗糙面也可確保殼體2〇具有較好之外觀。 [0023] 可以理解，若非晶合金基材表面外觀較好，且具有一定 的化學活性時，殼體可無需鍵膜層。如圖3所示殼體3〇 包括非μ合金基材32及形成於非晶合金基材32表面之塗 層34。塗層34包括與非晶合金基材32表面直接相連接之 黏合層344，及形成於黏合層344上且處於外表面之外覆 φ 層346。表面處理過程係先於非晶合金基材32上塗佈黏合 劑形成黏合層344及塗佈面漆形成外覆層346。 [0024] 可以理解’在上述非晶合金基材上還可形成圖案層，例 如於非晶合金基材表面上印刷圖案形成圖案層，或在實 施方式二之殼體20中直接將底層241做成圖案層。由於具 有塗層之保s蔓’圖案層可避免被磨損或腐钱。另，上述 表面處理方法並不限於製備殼體，例如其還可用於處理 部分表面處於設備外部之零件之表面。 · [0025] 綜上所述，本發明符合發明專利要件，爰依法提出專利 申請。惟，以上所述者僅為本發明之較佳實施方式，本 發明之範圍並不以上述實施方式為限，舉凡熟悉本案技 藝之人士，於援依本案發明精神所作之等效修飾或變化 ，皆應包含於以下之申請專利範圍内。 【圖式簡單說明】 [0026] 圖1係本發明較佳實施方式一之殼體。 〇96l4244(f 單編號 Α0101 第8頁/共13頁 1013004735-0 101年.01月04日修正替無頁 1360479 ' [0027] 圖2係本發明較佳實施方式二之殼體。 [0028] 圖3係本發明較佳實施方式三之殼體。 【主要元件符號說明】^ J Thus, the adhesive layer 144 enhances the bonding force between the outer cover 146 and the coating layer 142, thereby preventing the outer cover 146 from falling off the amorphous alloy substrate 12, and avoiding or reducing the oxidation or corrosion of the coating layer 142. And since the adhesive layer 144 is composed of a polymer material, it also has a certain elasticity, so that the softness of the coating 146 outside the outer surface is increased, thereby lifting the hand of the casing 10 [0021] In addition, in the casing 10 During the surface treatment, by depositing the coating layer 142 or changing the color of the topcoat by using different targets, it is also easy to change the color of the casing 10 to meet different appearance requirements. When the insulating coating layer 142 is formed by the insulating vacuum phosphating method, the insulating coating layer 142 allows the electromagnetic signal to pass through, so that it does not affect the predetermined radio frequency (RF) performance and electromagnetic compatibility (ESD) performance of the portable electronic device.

The underlayer 241 is formed on the surface of the amorphous alloy substrate 22 between the amorphous alloy substrate 22 and the plating layer 242. The bottom layer 241 may have a thickness of from 1 micron to 30 microns. The surface treatment process is performed by applying a primer to the amorphous alloy substrate 22, and sequentially forming a bottom layer 241 by leveling, solidifying, etc., and then depositing a coating layer 242 on the bottom layer 241 in sequence, and applying a binder to form an adhesive layer 244. And coated topcoat formed outside 1013004575-0 Page 7 / 13 pages 1360479 101 years 01 ^ 04 • Nuclear replacement ϊ " 'Cladding 246. The main component of the primer may be an acrylic resin, and the curing method may be heat curing or photo curing. It can be understood that since the bottom layer 241 is present in the casing 2, the surface of the amorphous alloy substrate 22 and the bottom layer 241 can ensure a good appearance even if it is a rough surface. [0023] It can be understood that if the surface of the amorphous alloy substrate has a good surface appearance and has a certain chemical activity, the shell may not require a bonding layer. The casing 3'' shown in Fig. 3 includes a non-μ alloy substrate 32 and a coating layer 34 formed on the surface of the amorphous alloy substrate 32. The coating layer 34 includes an adhesive layer 344 that is directly bonded to the surface of the amorphous alloy substrate 32, and an φ layer 346 formed on the adhesive layer 344 and outside the outer surface. The surface treatment process is performed by applying an adhesive to the amorphous alloy substrate 32 to form an adhesive layer 344 and coating the top coat to form an outer cover layer 346. [0024] It can be understood that a pattern layer may be formed on the above amorphous alloy substrate, for example, a pattern forming pattern layer is printed on the surface of the amorphous alloy substrate, or the bottom layer 241 is directly formed in the casing 20 of the second embodiment. Patterned layer. The coated layer can be protected from wear or money by the coated layer. Further, the above surface treatment method is not limited to the preparation of the casing, and for example, it can also be used to treat the surface of a part whose surface is outside the apparatus.
