Description

工件表面色处理方法 技术领域
本发明关于工件表面色处理方法, 尤指一种以阳极处理表面为基础的工件表 面色处理方法。 背景技术
许多电子科技产品或生活用品, 会采用金属作为材质, 而取用金属材质的原 因, 除了强固、 耐用的基本功能以外, 另外是因为金属材质的金属光泽可以增加 产品的质感, 甚至更象征尊贵气派。 由于金属光泽的特性在于反光性佳, 但是相 对也不容易上色, 主要是因为金属的表面孔隙相对较小, 即色彩颜料不容易附着, 因此多必须采用诸如电镀等电化学方式进行涂装。 然而, 电镀虽可以将颜色附着, 但仍然深蚀性不足, 而容易脱落。
为了强化或增加金属表面的装饰, 而且仍然保持金属光泽与质感, 且兼具抗 氧化等防锈、 防磨功能, 该金属表面的处理技术受到重视。
虽然有先前技术在金属机壳表面先进行阳极处理, 然后以印刷附着上所需的 颜色或图案, 但是此种方式对于金属容易形成大范围的披覆, 因此不容易维持金 属表面光泽, 且该印刷所附的颜色或图案由于耐磨度较低而容易脱落。 而且以印 刷对于颜色与图案附着的工序较为繁琐而不易精确施工, 且该印刷上色或图案必 须大量施工, 对于小范围的装涂, 或者少量施工, 不容易进行灵活性的变换且缺 乏变化。 发明内容
有鉴于该先前技术的问题, 本发明者认为应有一种改善的系统以及方法, 为 此设计一种工件表面色处理方法, 其步骤至少包括: 于一工件表面以阳极处理形 成多孔的保护膜; 以该孔的纵深形成开口向上的阳极管胞; 继而由该开口填充色 料于该阳极管胞; 加压至干燥; 然后该工件表面浸没于一封孔剂, 以对该阳极管 胞完成封口; 取出已完成表面的保护膜封孔程序的工件干燥后固型。 从而, 本发 明虽然同样进行工件表面阳极处理, 但更衍生以下的优点:
1.快速完成图形、 文字、 数字或符号。 2.使图形、 文字、 数字或符号完全封存于阳极氧化层内。
3.没有残存多余的色料, 涂布完成后, 不需再去除多余的色料。
4.色料使用量少, 所以可大幅缩短干燥的时间。
5.色料皆填充至阳极氧化层的管胞内, 避免使用时被刮除的风险。
6.使图形、 文字、 数字或符号的线条与色彩更加细致与清晰。
本发明可以于该开口填充色料于该阳极管胞的前或后步骤, 对于该工件进行 染色, 以令该阳极管胞本身或未含括的部分得受该染色的影响, 而使得工件表面 颜色呈现更加饱和与达成更多色彩的变化, 且透过填充色料与染色的相辅着色, 大幅减少阳极管胞遗漏着色。 附图说明

图 2为本发明阳极管胞填充色料示意图。
图 3为本发明对开口填充色料于阳极管胞之前染色示意图。
图 4为本发明对开口填充色料于阳极管胞之后染色示意图。

以下藉由图式的辅助, 说明本发明的内容、 特色与实施例, 俾使贵审对本发 明有更进一步的理解。
请参阅图 1所示, 本发明关于一种工件表面色处理方法, 其步骤至少包括: 1.于一工件 (较佳为金属)表面以阳极处理形成多孔的保护膜; 以该孔的纵深形 成开口向上的阳极管胞 (1) (配合图 2所示);本程序的前置作业可以将工件表面清洁 以及化学抛光等, 以令工件更适合于加工。 该阳极处理会在工件表面产生一层膜 厚约在 6 μ πι至 15 m左右 (不拘)多孔性的氧化层, 此氧化层称为阳极皮膜, 因为 所形成的表面为多孔性质, 具有优秀的渗透性。
2.由该开口填充色料 (2)于该阳极管胞 (1)(配合图 2所示); 值得一提的是本发明的色料 (2)的填充分布成选自图案、 文字、 符号、 数字群 组之一的轮廓。 而且该色料 (2)可以依据环保、 工件特性选自有机色料或非有机色 料。且本发明亦可以依据加工所需而将该色料 (2)选自以下之一: 感光色料、 UV色 料、 环保油墨、 荧光色料、 变色色料、 防伪色料、 金属色料、 电子色料与导电色 料。
而为更精准填充, 本发明的填充方式更可以以针头注射为之。
3.加压至干燥;干燥的时间可为 0.1秒到数小时。或给予烘烤箱或 UV (紫外线) 照射。
4.该工件表面浸没于一封孔剂, 以对该阳极管胞 (1)(配合图 2所示)完成封口; 5.取出已完成表面的保护膜封孔程序的工件元件干燥后固型。
请参阅图 3所示, 本发明当进行对开口填充色料 (2)于该阳极管胞 (1)之 「前」, 可以先对该工件进行染色, 形成染色层 (A), 由于染色过程使得该阳极管胞 (1)旁的 部分,因为染色的色料,即染色层 (A)而受染颜色 (该颜色较佳与该填充色料 (2)同色, 亦可以为不同色), 实施例中以不同线条表现乃为区别的用, 惟并非显示同色或不 同色, 而使得该阳极管胞 (1)未含括的部分得受该染色, 而对开口填充色料 (2)于该 阳极管胞 (1)之后, 整体工件的颜色形成色料均匀、 充分。 又, 虽然该染色, 即染 色层 (A)可能一部分先渗入该阳极管胞 (1),然不影响该阳极管胞 (1)的嗣后的色料 (2) 填充。
本发明亦可于对开口填充色料 (2)于该阳极管胞 (1)之 「后」, 请参阅图 4所示, 再对该工件进行染色, 形成染色层 (A), 该染色的色料可能对该阳极管胞 G)已经填 充的颜色覆盖, 但当该染色与该填充色料 (2)同色料时, 可以使得该阳极管胞 (1)的 颜色更为饱和。 同时也可以将填充色料 (2)不足, 或者未填到的部分, 以染色层 (A) 将其替代或补足, 本发明的染色可采用与该填充色料 (2)不同的颜色, 可以由业者 自身决定。
从而, 本发明可使颜色更加饱和与达成更多色彩的变化。
由于色料 (2)封存于阳极处理的保护膜阳极管胞 (1), 因此色料 (2)所分布的图 案、 文字、 符号、 数字披覆于工件表面上, 除使整个工件增加质感美观外, 且色 料 (2)已兼具阳极处理的高度硬度, 故不易脱落于工件的表面, 增加产品的寿命。
本发明的填充, 可以采用連续供墨式(Continuous)技术以及供需式 (Drop-on-Demand)技术,其中供需式 (Drop-on-Demand)又可分为一、热能式 (Thermal) 又可称为热气泡式 (Thermal Bubble) 二、 静电式 (Electrostatic;)、 三、 压电式 (Piezoelectric). 四、声波式 (Acoustic)等技术, 其中压电式 (Piezoelectric)又可分为挤 压式 (Squeeze Tube)、弯曲式 (Bend Mode),推压式 (Push Mode),剪力式 (Shear Mode) 等方式, 将油墨输出成滴墨、 射墨、 喷墨效果, 并产生极细小的油墨粒子或分子, 油墨粒子或分子大小可由 400微米 (Micron; Micrometer)至 1奈米 (Nanometer), 并 将不同颜色的极细小油墨, 分别填充至 1个以上的阳极管胞 (IX配合图 2所示)内。
综上所述, 认为本发明当符合专利法的规定。 以上所述者, 仅为本发明的一 较佳实施例而已, 当不能以此限定本发明的范围。 即大凡依本发明申请专利范围 所作的均等变化与修饰, 皆应仍属本发明专利涵盖的范围内。
