Description

一种化妆品收纳盒的IMD成型工艺
技术领域
本发明涉及化妆品收纳盒生产技术领域，更具体地说是一种化妆品收纳盒的IMD成型工艺。
背景技术
IMD的中文名称：模内装饰技术，亦称免涂装技术。英文名称：In-MoldDecoration，IMD是国际风行的表面装饰技术，表面硬化透明薄膜，中间印刷图案层，背面注塑层，油墨中间，可使产品耐摩擦，防止表面被刮花，并可长期保持颜色的鲜明不易退色。
现有技术当中，厂家将IMD成型的装饰片材直接用胶水粘在化妆品收纳盒上，这种做法会带来以下缺陷：（1）涂胶后需要将装饰片材小心翼翼按在化妆品收纳盒上，指甲会不经意划伤装饰片材，而且手工安装会使装饰片材错位，所以市场上装饰片材在化妆品收纳盒上歪歪扭扭的存在不在少数；（2）涂胶的均匀度无法得到，以及手工按压的力度和施力点在单一点上，所以会造成装饰片材安装不平整；（3）最后，就是装饰片材与化妆品收纳盒之间结合不牢靠，早早脱落。
发明内容
本发明的目的在于克服现有技术以上缺陷，提供一种操作简化、成型效率提升、结合牢靠、合格率更高、成型品质更好的化妆品收纳盒的IMD成型工艺。
为了达到以上目的，本发明是通过以下技术方案实现的：一种化妆品收纳盒的IMD成型工艺，其特征在于，包括以下步骤：
（1）选材：选取装饰片材毛坯，所述装饰片材毛坯的表面为硬化透明薄膜层，内面为基材层，中间为油墨层，所述油墨层上印制有多个按矩阵方式排列的图像单元；
（2）备胶：选取热熔特性的粘合剂，将粘合剂在所述基材层背面形成一层薄膜底涂，冷却后生成固态，得到成品装饰片材；
（3）裁料：沿着所述油墨层上各个图像单元的轮廓线逐一裁剪下来，将所述成品装饰片材进行分解，得到多个图像单元装饰片；
（4）复合：择取一个图像单元装饰片，放入到与其大小相匹配的化妆品收纳盒注塑模具中，定位后合模注塑，将液态高温基材注射在图像单元装饰片的背面，粘合剂受热从固化到液化，使树脂与图像单元装饰片结合成一体；
（5）成型：冷却后固化脱模成型。
本发明在装饰片材与化妆品收纳盒的结合工艺方面再次采用IMD技术，也就是将装饰片材放入到化妆品收纳盒模具当中进行模内注塑，在克服装饰片材的基材与化妆品收纳盒的基材之间无法结合的问题，采用在装饰片材的背面形成一层固态的薄膜底涂，关键薄膜底涂是需要选用热熔特性的粘合剂，如此使装饰片材与化妆品收纳盒的结合达到以下效果：操作简化、成型效率提升、结合牢靠、合格率更高、成型品质更好。
作为优选，在上述步骤（2）中，热熔特性的粘合剂为具有功能型热粘性粘合剂的IMD粘合剂。
IMD粘合剂，作为功能型热粘性粘合剂，用于模内装饰注塑成型(IMD)，对难以粘合的制品和薄膜，例如ABS、AS、PVC、PS、PP等具有良好的附着性。IMD粘合剂在印刷或复合前的底涂，改善薄膜的表面附着性，适用性广，对PE、PP、PVC等低粘性薄膜；以及PVF、PVDF、ETFE等不粘性氟膜亦有明显的粘合促进作用。
作为优选，在上述步骤（1）中，多个图像单元为单一光栅图、单一光纹图或光栅图和光纹图的组合。
光栅图，利用特种光学材料（通称光栅材料）在平面上展示出栩栩如生的立体世界，匪夷所思的立体效果。手摸上去是平的，眼看上去是立体的，有突出的前景和深邃的后景，景物逼真。各类型图像都可以做出立体效果。是结合数码科技与传统印刷输出的技术，用一组序列的立体图像去构成一张图片，图片表面履盖着一层的光栅所组成的。光栅画通过不同加工和材料的选择，还可以做出网上所说的二变，三变，旋转，缩放，彩虹等效果，实际都是光栅成像原理上的引申做法。由于光栅立体画的成本比较高，任何保存好库存的光栅立体画就非常重要。
光纹图，又名折射光纹图，通过纸面压纹、凹版印刷、丝网印刷、浮雕压纹、重压烫金压纹来体现强烈折射激光折光效果，它使设计图与色彩纹理结合产生出各种放射、明暗、旋转、波浪等极强流动视觉效果变化。不同形式的线条烫金压纹效果，直线压纹、弧线压纹、三角线压纹、波浪线压纹、2D-3D幻变折光压纹、同心圆压纹、同心矩形压纹及各种图像压纹烫金效果，将印刷光纹、烫金同压折光光纹的设计领域推向了一个更高的层次。它将所需折光光纹图案转压/烫印到金银卡、镭射彩虹素面卡纸/喷铝纸上，形成强烈折射逻辑光纹折光效果。它产生的印刷折光光纹、折光光纹压纹、烫金同压折光光纹、磨砂冰花叠加光纹的产品豪华夺目，色彩亮丽光泽，精美绝伦，七彩金雕镭射折光，金碧辉煌，金属质感，磨砂冰花蚀刻，产品整体效果层次和品位远比普通印刷/压纹/烫金压纹质高品贵。这种因折射产生的变化复杂多变，扫描仿冒造假均无法进行，具有较强防伪功能。
有益效果：本发明在装饰片材与化妆品收纳盒的结合工艺方面再次采用IMD技术，也就是将装饰片材放入到化妆品收纳盒模具当中进行模内注塑，在克服装饰片材的基材与化妆品收纳盒的基材之间无法结合的问题，采用在装饰片材的背面形成一层固态的薄膜底涂，关键薄膜底涂是需要选用热熔特性的粘合剂，如此使装饰片材与化妆品收纳盒的结合达到以下效果：操作简化、成型效率提升、结合牢靠、合格率更高、成型品质更好。
