复合表面处理方法
技术领域
本发明涉及一种表面处理方法，尤其涉及一种复合表面处理方法。
背景技术
表面处理的技术日新月异，尤其在手机塑料壳上的应用，更是多姿多采竞争激烈，客户对高彩、立体触感的要求也越来越高，且对侧边包覆的问题越来越重视。
然而，现有技术中，常常不能兼顾侧边包覆及高彩、立体触感的问题。

具体实施方式
下面请结合附图1-9及实施例对本发明提供的一种复合表面处理方法作进一步说明。
请参阅图1-9，本实施例提供一种复合表面处理方法，其包括步骤：
S1，请参阅图1-3，提供一基壳10。
在本实施例中，该基壳10为一手机壳。该基壳10包括一外表面11及四个垂直于该外表面11且与该外表面11相交的侧面12。
在其他实施例中，该基壳10还可以为笔记本等其他电子装置或是机械装置的壳体。
S2，请参阅图4-7，利用真空热转印或烤漆制程形成背景图层30，该背景图层30包覆该外表面11及四个该侧面12。
在本实施例中，是利用真空热转印制程形成该背景图层30的。其具体过程如下：
S21，请参阅图4-5，提供一热转印膜20。
在本实施例中，该热转印膜20包括一热转印层21及一形成在该热转印层21的一表面上的离型膜层22。该热转印层21包括一黏胶层211、一形成在该黏胶层211的一表面上的图形层212及一形成在该图形层212的远离该黏胶层211的表面上的第一防护层213。
其中，该离型膜层22形成在该第一防护层213的远离该图形层212的表面上。该离型膜层22是以具水溶且可双轴延伸之特性材料所制成，如：聚乙烯醇、聚对苯二甲酸乙二酯等，该离型膜层22的面向该第一防护层213的表面设置有压纹221，该压纹221是利用压印或雕刻于面向该第一防护层213的表面上形成的立体状的曲面。该第一防护层213由树脂材料制成，该第一防护层213可以经由喷涂、涂布、平版印或网版印等方式形成。该第一防护层213部分填充于该压纹221内，进而形成立体状的接触面2131。该黏胶层211由热熔胶制成，加热可融合于该基壳10的表面。
在其他实施例中，该热转印膜20并不局限于上述结构与特性。例如，该热转印膜20还可以为具有光线色泽变化效果的热转印膜，具有金属质感的热转印膜，具有3D镂空结构的热转印膜等。
S22，请参阅图6，利用热转印机（图未示）在加热加压且真空的条件下，将该热转印膜20形成在该基壳10上。该热转印膜20包覆该基壳10的该外表面11及四个该侧面12。
由于该离型膜层22为利用具双轴延伸之特性材料所制成，因此在加热加压且真空的条件下，该热转印膜20可依照该基壳10表面的弧度进行弯曲，从而使该第一防护层213与该图形层212包覆该基壳10的该外表面11及该侧面12。
S23，请参阅图7，去除该离型膜层22，进而形成该背景图层30。
该背景图层30即为去除了该离型膜层22后的热转印图层21。
在本实施例中，由于该图形层212位于该第一防护层213与基壳10之间，因此该第一防护层213可保护该图形层212不被外力破坏；由于该第一防护层213表面形成有立体状的接触面2131，因此可增加使用者之触感；若该接触面2131的立体形状配合该图形层212的图样时，更可增加该背景图层的立体感。
S3，请参阅图8-9，利用紫外线固化数码喷墨的方式在该背景图层30上形成一表面图层40，进而得到一机壳100。
在本实施例中，该表面图层40包括一基底层41、一打印图形层42及一第二防护层43。该基底层41形成在该第一防护层213的远离该图形层212的表面上且与该外表面11对应，该打印图形层42形成在该基底层41的远离该第一防护层213的表面上，该第二防护层43形成在该打印图形层42的远离该基底层41的表面上。
在其他实施例中，该表面图层40还可以包括一形成在该基底层41和该打印图形层42之间的白底层。
在本实施例中，通过一紫外喷墨打印机(图未示)形成该表面图层40。具体地，在打印前，使用者可先控制该紫外喷墨打印机的打印模块，使打印模块中供打底油墨(用于形成基底层41)输出的喷墨头可先在该背景图层30上输出打底油墨，在输出该打底油墨的同时，凭借打印模块两侧本身装设的紫外灯的照射，使打底油墨固化，以形成该基底层41；尔后，再令打印模块控制装有色彩油墨（用于形成打印图形层42）的喷墨头装置进行预设图案的输出，同时凭借紫外灯的照射，使色彩油墨固化，以形成该打印图形层42；最后，再令打印模块控制喷墨头装置一侧的供亮光油墨（用于形成该第二防护层43）输出的喷墨头进行亮光油墨的涂布，以形成具有表面亮光效果与预防打印完成品图案刮落的功能该第二防护层43。
本发明提供的复合表面处理方法，1）利用真空热转印或烤漆制程形成的背景图层既能解决边缘包覆的问题，又能增加该机壳100的触感与立体感；2）在利用紫外线固化数码喷印的方式在该背景图层30上形成该表面图层40的过程中，利用紫外喷墨打印机的装有色彩油墨的喷墨头装置进行预设图案的输出，既能丰富该机壳100表面的色彩，又能使该机壳100表面的图样多样化。
可以理解的是，以上实施例仅用来说明本发明，并非用作对本发明的限定。对于本领域的普通技术人员来说，根据本发明的技术构思做出的其它各种相应的改变与变形，都落在本发明权利要求的保护范围之内。
