Description

用于眼镜的复合热塑性塑料板材、装饰部件及其制备方法
技术领域
本发明涉及复合热塑性塑料板材、装饰部件及其制备方法。特别地,用于例如眼镜板材领域,或其它装饰部件领域。
背景技术
目前市面上具有图案的眼镜用热塑性塑料板材一般通过丝网印刷方法制作, 丝网印刷需要制作胶片,成本高,生产周期长。由于丝网印刷方法制作采用的油墨与板材接合强度较低,需采用胶粘剂或其它溶剂(如拼料水)加强其结合强度。
在利用转移技术制作图案花纹的热塑性塑料板材中, 日本专利文献申请号: JP2003-138051, 公开日: 2004年12月2日, 其提及利用热升华墨水热压转印, 由于油墨渗透/晕染到塑料板材中, 制作图案花纹模糊不清, 在热压时, 接合强度较低。且该方法制作的花纹树脂板花纹只在内部中间位置,否则粘附力较差。
发明内容
本领域现需要图案花纹,具有高清晰度,栩栩如生的复合热塑性塑料板材及其制备方法。本发明提供的复合热塑性塑料板材和装饰部件(如眼镜部件)色彩圆润丰富,不褪色,不会受到外界因素的影响,有立体感。特别地,用于例如眼镜板材领域,或其它装饰部件领域。
此外,该制备本发明复合热塑性塑料板材和装饰部件的加工方法工艺简单,生产周期短。进一步地,装饰部件(如眼镜部件)多个面具有图案花纹, 增加了眼镜部件的美观, 最大限度地满足本领域的需求。

为了达到上述目的,本发明涉及下述方面:

- 任选地,将打印好图案的转印材质进行烘干去除溶剂和/或水分,以保证转印后的图案的清晰度,烘干温度例如为40℃-70℃,甚至50-65℃,
- 从烘干后的转印材质上把图案转印至中间层上,优选转印时温度是100℃-250℃。
方面10. 根据方面9所述的方法热塑性塑料板材,其中,打印使用的油墨为含有升华性染料的热升华油墨。

在本发明中所使用的中间层可以以本领域技术人员所掌握的方式制备得到,也可以通过下述方法获得,如:
中间层的制作
在中间层包括图案层的情况下,该方法包括形成图案中间层的如下步骤:
利用计算器辅助设计所需的图案花纹, 将所需图案打印至转印材质上,其中,优选,转印材质为纸,打印机使用装有热升华油墨的喷墨打印机, 其中,打印使用的油墨例如为含有升华性染料的热升华油墨。为了增加后续复合板材的结合强度,优选油墨为水性油墨。其中,将所需图案打印至转印材质上时将空气湿度保持在45-80%,甚至50-70%。
任选地,将打印好图案的转印材质进行烘干去除多余的溶剂和/或水分,避免油墨在转印材质上的晕染和/或渗透,保证图案在转印材质的清晰度的同时,转印后的图案的清晰度相应得到提高,烘干温度例如为40℃-70℃。
将转印纸上打印好图案花纹热转印至中间层板材上,优选转印时温度是100℃-250℃,转印时间例如是30秒-200秒。为了达到较好的转印效果,优选地,图案转印到薄片板材上形成图案层,这样批量生产的转印效果稳定,不易产生色差。再优选地,将转印好图案板材薄片进行烘干,使图案层以及油墨固定在板材的表面,防止油墨向深层和表面渗透晕染,达到图案更佳清晰度。从烘干后的转印材质上把图案转印至中间层上。
其中当中间层包括实物时,在中间层与相邻层结合的内表面上固定有实物。如果实物为薄片状,可以采用胶粘剂将实物固定在设计的位置,这样熔接复合热塑性板材时,实物不会移动,达到设计需要的外形和位置要求。如果实物较厚,或有立体效果,应该根据设计,在中间层和/或相邻层的特定位置制作外形与实物相同或相近的凹坑,将根据设计摆放在相应的凹坑位置,熔接复合热塑性板材时,实物外形保持完整,不会移动、损坏或变形,达到设计需要的外形和位置要求,易于控制产品质量、重复生产、产品质量达到规模化生产一致性。任选地,所述各个中间层之间或中间层与上层或中间层与下层之间具有一层或更多层的热塑性片材层作为阻隔层。
同时,各个中间层之间或中间层与上层或中间层与下层之间具有一层或更多层的热塑性片材层作为阻隔层,以防止复合板材结合后,不同颜色层之间的渗透(例如油墨或色粉等的渗透)而产生的渗色效果,达到设计所需的清晰外观效果。
其中当中间层包括图案和实物的片材时,实物固定在与图案层同一面或不同面的片材上。实物摆放可以根据设计结合图案固定(胶粘剂/凹坑)在特定位置,达到图案和实物结合的设计效果,从而产生图案和实物有独特的对位效果。另外,也可以利用一个或多个中间层的结构,将不同的图案层,阻隔层,或/和实物层分开,从而产生图案和实物之间有一定空间的立体效果。
本发明中涉及的烘干和/或缩水处理,其可以例如如下方式实施:
将热塑性塑料板材的不同层(上中下)放入烘炉中进行烘干和/或缩水处理, 去除不必要的成分,例如,水,并保证产品尺寸的稳定性. 具体的加工条件,根据材料和产品要求具体进行调整,其中烘干温度为50-150℃,时间5-48小时。
进一步具体地,本发明中涉及的高频熔接复合热塑性塑料板材,其可以例如如下方式实施:
将上面得到的具有图案和/或实物的中间层与上层和/或下层进行结合,该结合使用高频熔接机进行。优选地,为了得到产品有图案、实物效果,上层和/或下层会根据设计选用透明, 半透明的热塑性塑料板材。
将不同层的热塑性塑料板材根据设计所需进行上,中和/或下层的摆放,高频熔接机熔接时需要控制电流,熔接时间和冷却时间。其中高频熔接机熔接时间是大于15秒,优选大于20秒,但小于5分钟,优选小于1分钟,甚至是30-50秒。电流是大于0.2A,优选大于0.5A,但小于5A,优选小于2A,甚至是0.6-1.3A。控制电流,熔接时间需要根据材料,板材厚度和中间层材质(图案,实物等)进行调整,以达到结合强度的同时,中间层的外观保持良好(图案清晰,实物外形以及定位良好)。为了保持复合板材的外形,需要进行冷却,冷却时间大于0.5分钟,优选大于1分钟,但小于5分钟,优选小于3分钟,甚至是约2分钟。
通过以上不同工艺的改进和控制,利用热升华油墨打印图案转印技术,转印图案到热塑性片材上之后,并采用烘干工艺,对每个转印工序的产品进行处理,再用高频机进行瞬间熔接,避免了油墨的渗透和/或晕染,热塑性片材得到的复合热塑性板材图案清晰, 色彩丰富且边缘也具有图案,结合强度也非常好。
