Description

一种橡胶产品的印制方法
技术领域
本发明涉及一种印制方法，具体是一种橡胶产品的印制方法。
背景技术
橡胶产品的印制方法在企业生产中应用广泛，尤其是在电视机等电子产品领域中，控制键一般采用橡胶材质制成，需要将橡胶材质表面印刷有图像，使得区别各按键的功能，便于人们操作使用。
但是软质橡胶材质的按键本身很软是无法印刷的，必需经过一道加热加压的硫化程序，硫化处理使得橡胶取得高弹性，也让其表面变硬，才会产生印刷所需的固定形状，现有的橡胶产品印制方法只有单色印制，以保障成品的成功率，每多印一种颜色就需干燥烘烤处理，热涨冷缩之效应明显，成功率也随之下降，只能通过一片一片进行人工印刷作业，提高了制造成本，也影响到自动化的整个制程。
发明内容
本发明的目的在于提供一种橡胶产品的印制方法，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种橡胶产品印制方法，首先将要印刷于橡胶产品上的图案印刷层相对应地印刷于片材上，其次将要成为橡胶产品的橡胶材经过混练、加压加热过程，把印好的片材送入模具中加热加压进行压制，位于片材上的印刷层在加热过程中转印至橡胶材表面，橡胶产品进行脱模时片材分离，透过印于片材上的印刷层将图案或颜色转印至成型的橡胶产品立体各面上。
作为本发明进一步的方案：所述片材的材质为PC、TPU或PET中的任意一种。
作为本发明再进一步的方案：所述片材与橡胶材正对抵接之前需要将片材置入烤箱中预缩处理。
作为本发明再进一步的方案：所述片材为两片，分别夹住橡胶材，同时进行正反两面转印。
与现有技术相比，本发明的有益效果是：该方法运用平板印刷与加热加压技术，使预先印于片材上的图案颜色或图案及标示等印刷层进行转印，将图案转印至橡胶材印刷层上，因为片材是配合橡胶材印刷的需求进行印制、裁切，在成形时与其同时间进行加热加压，片材在退模时自动分离，且片材也可以结合于橡胶材上与橡胶材形成加强结构；本发明可制造立体印制型态的橡胶产品，印刷的橡胶材质上无死角，橡胶产品的印刷精美，提高了印刷效果。

具体实施方式
下面结合具体实施方式对本发明的技术方案作进一步详细地说明。
请参阅图1-7，一种橡胶产品的印制方法，首先将要印刷于橡胶产品上图案的印刷层5相对应地印于片材3上，其次将要成为橡胶产品的橡胶材1经过混练、加热、加压过程，把印好图案的印刷层5转印至橡胶材1上，然后公母模4进行脱模时片材3分离，片材3也能直接压接至橡胶材1上，使透过印于片材3上图案印刷层5转印至凸出成型的橡胶产品的立体各面上。
本发明于橡胶材1上下表面各夹一片具印刷层5的片材3，同时进行转印至橡胶材1，达到正反两面同时印刷的功能；其中片材3的材质为PC、TPU或PET中的任意一种，片材3是的材质是硬质的，可以进行直接的套色印刷，对印刷与颜色的精准度及质量能有更好的掌控，将片材3以及橡胶材1对正完全，进行在100℃左右之加温加热成型，完成转印过程，且该方法可进行立体转印，在凸出按键的底面与周边都能被印刷，片材3在印刷使用之前先经过烤箱预缩处理，避免因多次印刷烘烤而产生不良的热涨冷缩效应。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
