The patterned barrier layer 2 divides the outer surface 3 of the aluminum-containing article 1 into a plurality of wood texture pattern regions 11 which expose a portion of the outer surface 3, and a plurality of non-texture pattern regions 12 covering the other portion of the outer surface 3, the wood texture pattern region 11 and The outline of the non-textured pattern area 12 extends substantially in a curved direction along a base direction X. The contours of the wooden texture pattern area 11 and the non-texture pattern area 12 are matched to each other to form a wood annual ring outline. In detail, the patterned barrier layer 2 is formed by coating a photoresist layer on the outer surface 3 of the aluminum-containing article 1, the photoresist layer covering the first surface 5 and the second surface 10, and then a flexible After the photomask is placed over the aluminum-containing article 1 and aligned with the outer surface 3, the flexible mask is vacuum-applied to the outer surface 3 of the aluminum-containing article 1, and then the photoresist layer is patterned and exposed. In the step, the intermolecular bond of the photoresist layer is interrupted by ultraviolet light, and then the photoresist layer is broken by a developing solvent to form a patterned barrier layer 2 by a portion of the photoresist layer that is broken by the molecular bond. In addition to the above-described forming method, the patterning barrier layer 2 can be formed on a plastic film substrate, such as propylene oxide (PO) or polycarbonate (PC), to form a desired pattern, that is, a patterned film, and then The film is then covered on the outer surface 3 of the aluminum-containing article 1. The patterned film covers the first surface 5 and the second surface 10, and then vacuum-filmed, so that the patterned film is closely attached to the film. The outer surface 3 of the aluminum product 1, when the patterned film is adhesively coated on the outer surface 3 of the aluminum-containing article 1 and covers the first surface 5 and the second surface 10, and finally the plastic film substrate and the aluminum-containing material Product 1 Separating, leaving the desired pattern on the aluminum-containing article 1 described above, completes the outer surface 3 of the aluminum-containing article 1 to form a patterned barrier layer 2.

參閱圖1及圖5,木質肌理處理步驟200是將表面形成有圖案化阻擋層2的含鋁製品1浸入一由無機酸或有機酸及其鹼金屬鹽組成的電解液中並電連接一電源進行木質肌理電解蝕刻,以在含鋁製品1的外表面3的各木質肌理圖案區11形成多數間隔設置且大致上沿著基礎方向X直線延伸的線狀溝紋111,此線狀溝紋111搭配間隔分佈即呈現類似木材纖維的肌理分佈。詳細地說,在電解蝕刻過程中,電解液中的酸根離子與鋁離子結合形成電阻很高的混合膠體化合物,並覆蓋於含鋁製品1表面形成阻擋膜層。在電解蝕刻過程中,上述混合膠體化合物的阻擋膜層是生成反應與溶解反應交替進行,如此一來,在阻擋膜層較薄的部位,電流密度較高,導致含鋁製品1表面局部溶解,並伴有大量氣體產生,氣體上升的軌跡,會加速阻擋膜層的溶解,而使含鋁製品1氧化而形成對應氣體上升軌跡的線狀溝紋111。然而,線狀溝紋111的長度、寬度、深度及線狀溝紋111的分布密度是可藉由電解液的組成物配比及所施加於含鋁製品1的電流密度大小進行調控,由於上述製程的條件是本技術領域業者所週知,因此在此不再多加贅述。 Referring to FIGS. 1 and 5, the wood texture processing step 200 is to immerse an aluminum-containing article 1 having a patterned barrier layer 2 formed thereon in an electrolyte composed of an inorganic acid or an organic acid and an alkali metal salt thereof, and electrically connect a power source.

In detail, during the electrolytic etching process, the acid ions in the electrolyte combine with the aluminum ions to form a mixed resist compound having a high electrical resistance, and cover the surface of the aluminum-containing article 1 to form a barrier film layer. In the electrolytic etching process, the barrier film layer of the mixed colloidal compound is alternately formed between the formation reaction and the dissolution reaction, so that the current density is higher at a portion where the barrier film layer is thin, resulting in partial dissolution of the surface of the aluminum-containing article 1, A large amount of gas is generated, and the trajectory of the gas rise accelerates the dissolution of the barrier film layer, and the aluminum-containing article 1 is oxidized to form a linear groove 111 corresponding to the gas rising trajectory. However, the length, width, depth of the linear groove 111 and the distribution density of the linear groove 111 can be controlled by the composition ratio of the electrolyte and the current density applied to the aluminum-containing article 1, due to the above The conditions of the process are well known to those skilled in the art and therefore will not be further described herein.

除膜步驟400是將經由去膜層步驟300後的含鋁製品1利用鹼性溶液,例如碳酸鈉(Na2CO3)或氫氧化鈉(NaOH),或是酸性溶液,例如硫酸(H2SO4)或磷酸(H3PO4),進行殘留於含鋁製品1表面上且為混合膠體化合物的阻擋膜層移除。 The film removing step 400 is to use an alkaline solution such as sodium carbonate (Na 2 CO 3 ) or sodium hydroxide (NaOH) or an acidic solution such as sulfuric acid (H 2 ) through the aluminum-containing article 1 after the stripping step 300. SO 4 ) or phosphoric acid (H 3 PO 4 ), the barrier film layer remaining on the surface of the aluminum-containing article 1 and being a mixed colloidal compound is removed.

參閱圖1及圖7,上色步驟500為先將經由除膜步驟400後的含鋁製品1進行陽極氧化,以在含鋁製品1表面形成一具有多數孔洞130的氧化膜層13;接著參閱圖8,對含鋁製品1進行染色製程,於氧化膜層13上形成一填滿孔洞130的著色層14。詳細地說,含鋁製品1的染色製程包含印刷法,如平版印刷、網版印刷,以及噴墨等印刷製程方式,或一般傳統染色法,如金屬鹽類(電解著色)、有機染料、無機鹽類(化學著色),最後參閱圖9,將氧化膜層13的孔洞130進行封孔處理。詳細地說,封孔處理是形成一保護層15封閉著色後的氧化膜層13,以保護孔洞130中油墨不受外力作用而有刮除或產生暈染情形,及提高其耐蝕、耐磨、耐曬等方面的性能。封孔處理包含金屬鹽封孔處理、有機物封孔處理或塗裝封孔處理,例如高溫80~100℃的醋酸鎳封孔。 Referring to FIGS. 1 and 7, the coloring step 500 is performed by anodizing the aluminum-containing article 1 after the film removing step 400 to form an oxide film layer 13 having a plurality of holes 130 on the surface of the aluminum-containing article 1; 8, a dyeing process is performed on the aluminum-containing article 1, and a coloring layer 14 filling the holes 130 is formed on the oxide film layer 13. In detail, the dyeing process of the aluminum-containing article 1 includes a printing method such as lithography, screen printing, and a printing process such as inkjet printing, or a general conventional dyeing method such as metal salt (electrolytic coloring), organic dye, inorganic Salt (chemical coloring), and finally, referring to Fig. 9, the pores 130 of the oxide film layer 13 are subjected to a sealing treatment. In detail, the sealing treatment is to form a protective layer 15 to block the colored oxide film layer 13 to protect the ink in the hole 130 from being scraped or caused by external force, and to improve corrosion resistance and wear resistance. Light fastness and other aspects of performance. The sealing treatment includes metal salt sealing treatment, organic material sealing treatment or coating sealing treatment, for example, nickel acetate sealing at a high temperature of 80 to 100 ° C.
