Description

一种导光装饰复合片材及其部件
技术领域
本发明涉及一种装饰片材及其部件， 特别是涉及一种应用于手机、 键 盘、 笔记本电脑、 计算机机壳装饰产业、 信息产业、 通信产业、 汽机车产 业、 家电产业、 游戏机、 化妆品与一般日用品、 文具用品、 运动器材等的 具表面装饰功能的一种导光装饰复合片材及其部件。 背景技术
传统的电子产品外壳常采用模内装饰技术， 其包含印刷、 热压、 射出 等塑料加工程序的整合工艺，虽然随着不同的技术 IMR (in-mold roller) /IML (in-mold labeling)/IMF (in-mold film)材料虽然有所差异， 但工艺成型原理基 本上均是相同的。 一般来说模内装饰技术工艺程序， 包括薄膜印刷、 热压 成型及射出成品等三个步骤： （1 )印刷工艺： 使用网版印刷、 数字印刷、 移印或烫印， 得到装饰性的可成型薄膜。 （2) 成型工艺： 利用高温热变形 方式使印刷薄膜变成要求的形状， 再经过精密裁切后成为预成型膜。 （3) 注 塑工艺： 将预成型膜置入射出机的模穴中， 注塑射出完成塑料件或产品。 除了印刷的装饰功能外， 所产生的成品并无其他导光功能。
颖台公司的中国台湾 201018581 公开专利数据中， 虽然膜材的表面有 结构， 是为了提升膜材弯曲时的延展性， 并非为了导入光线的作用。 为了 避免胶料射出成型过程， 造成表面结构变形影响美观， 因此表面结构材料 为热固型树脂， 所以膜材的变形量有限。 结构层在表面而印刷在另一面的 非结构面， 因此印刷效果不立体。
由此可见， 上述现有的电子产品外壳在结构与使用上， 显然仍存在有 不便与缺陷， 而亟待加以进一步改进。 为了解决其存在的问题，相关厂商莫 不费尽心思来谋求解决之道，但长久以来一直未见适用的设计被发展完成， 而一般产品又没有适切的结构能够解决上述问题， 此显然是相关业者急欲 解决的问题。 发明内容

请参阅图 1和图 2， 先将透明塑料膜 (德固赛压克力树脂 (Degussa 8N))， 以一支表面刻有微结构的热滚轮， 温度保持在 80〜： 120摄氏度之间， 将微 结构转印到塑料膜的一面， 再经过冷却滚轮降温定型， 如此可制得单面结 构透明基板 1。随即在已定型的微结构表面涂上一层耐热层， 其软化温度高 于第二支滚轮的设定温度至少 90〜150摄氏度； 第二支滚轮设定温度比第 一支滚轮高 10摄氏度至 30摄氏度之间， 以第二支滚轮转印微结构于基板 的另一面， 如此可制得双面结构透明基板 7。 其中该微结构， 是选自条紋、 菱镜、 半球形、 半圆柱状、 金字塔透镜、 菲涅尔结构或以上的组合。

实施例 3 : 以聚碳酸酯 PG (材料来源：出光 LC- 1500)为例， 当塑料由 T 型押出头押出后， 以一支表面刻有很多半球形图案的热滚轮， 温度保持在 70摄氏度至 120摄氏度（一般以 90度）之间，将半球形 凸结构转印到聚碳 酸酯膜的一面， 再经过冷却滚轮降温定型， 再让该膜经过第二支表面刻有 很多半球形图案的热滚轮， 温度保持在 130摄氏度至 180摄氏度之间， 其 中 凸结构的高低差与密度不均匀， 分布由一侧高低差 5微米（密度 0. 01 半球形 /平方厘米）至另一侧 80微米（密度 0. 8半球形 /平方厘米） ， 如此形 成如图 2中示的双面结构透明基板 7。 在一面喷上表面处理层 2 (瑞化股份 有限公司紫外线硬化底胶 POLYCHEM #T3 50150E)， 以数字印刷技术依据 需要印上装饰用的图紋印刷层 3，然后，再热复合（温度 80〜150摄氏度）一 层热熔胶接着层 6 (材料来源： 大东树脂的热塑性聚胺基甲酸酯 ）。 双面结 构透明基板 7另一侧表面涂上硬度 3Η以上的硬涂层 4 (材料来源：佑泽兴业 压克力树脂）， 以红外线加紫外线硬化， 如此形成如图 4中所示的直型内印 刷装饰片材 300。
实施例 4: 如实施例 2的制作程序， 但将其中一侧 Τ型押出头的流道 出口， 截面局部修改成呈梯型， 如此所押出的膜材， 在其中一侧的膜截面 呈喇叭型。 采用较窄的表面刻有很多半球形图案的热滚轮， 避开喇叭型截 面的位置。 其他工艺皆与实施例 2相同， 如此形成如图 5中所示的喇叭型 装饰片材 400。
实施例 5 :以实施例 1至实施例 4的装饰片材， 将硬涂层 4朝向模面， 以塑料（德固赛压克力树脂（Degussa 8N)或丙烯腈、 丁二烯、 苯乙烯共聚 物射出成型于接着层 6 面， 形成具导光功能的装饰塑料件。 在单面结构透 明基板 1 或双面结构透明基板 7的侧面选择凹凸结构的高低差与密度低的 一侧， 再将 4 毫米发光二极管（亿光光电股份有限公司， 59-146UTD/TR8) 光源 9安置于旁边， 如此便可得到如图 3至图 5所示的导光装饰复合部件。
实施例 6: 使用表面具有半球型微结构的模具， 将实施例 1至实施例 4的装饰片材，将硬涂层 4朝向模面，以塑料德固赛压克力树脂 (Degussa 8N) 或丙烯腈、 丁二烯、 苯乙烯共聚物射出成型于接着层 6面， 形成具导光功 能的装饰塑料件。 在单面结构塑料 11的侧面， 选择膜具转印的微结构的高 低差与密度低的一侧， 再将 4 毫米发光二极管（亿光光电股份有限公司, 59-146UTD/TR8)光源 9安置于旁边， 如此便可得到如图 6所示的导光装饰 复合部件。

以上所述， 仅是本发明的较佳实施例而已， 并非对本发明作任何形式 上的限制， 虽然本发明已以较佳实施例揭露如上， 然而并非用以限定本发 明，任何熟悉本专业的技术人员， 在不脱离本发明技术方案范围内，当可利 用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例，但 凡是未脱离本发明技术方案的内容， 依据本发明的技术实质对以上实施例 所作的任何简单修改、 等同变化与修饰， 均仍属于本发明技术方案的范围 内。
