Description
技术领域
本发明涉及数码印刷不干胶材料技术领域,尤其涉及一种适用于数码打印的不干胶材料及生产工艺。
背景技术
不干胶材料在日常生活中随处可见,大多以自粘标签、即时贴、压敏标签等形式出现,是以纸张、薄膜或特种材料为面纸,背面涂有粘合剂,以涂硅底纸为离型纸的一种复合材料,并经印刷、模切等加工成为成品标签。应用时,只需要将底纸剥离,轻轻一按,即可贴到各种被贴物的表面,也可以使用贴标机在生产线上自动贴标。不干胶广泛应用在各种商品上,如药品标签、食品标签、酒标签、电池标签、外箱标签、日化产品标签等等。
常见的不干胶打印材料,胶水层涂满整个面纸和离型纸,当放置在激光打印机或喷墨打印机中进行打印图文时,经过设备的温度和压力,涂在印刷面纸和底纸之间的胶液会熔漏,熔漏的胶液会沾污到激光打印机硒鼓、定影器和喷墨打印机的进纸组件或进纸单元,残留在内的胶液不易清除,打印其他纸张时还容易卡纸,造成机器故障,不仅使办公印刷设备的使用寿命缩短,还降低了印刷生产效率。
发明内容
为了克服现有技术不足,提出一种适用于数码打印的不干胶材料及生产工艺,以解决上述背景技术中提出的问题。
为了实现上述目的,本发明是通过如下的技术方案来实现:
一种适用于数码打印的不干胶材料,包括离型纸、胶水层和可打印面层,所述离型纸一侧面涂覆胶水层,胶水层的另一面贴有可打印面层,可打印面层为可打印纸张或可打印膜类,离型纸和可打印面层通过胶水层粘结,离型纸四周没有胶水层,为空白区,可打印面层四周没有胶水层,为空白区。
作为本发明的更进一步技术方案:所述可打印纸张为数码印刷用胶板纸、铜版纸,牛皮纸中的一种。
作为本发明的更进一步技术方案:所述可打印膜类为PVC、PET、PE拉丝膜、镭射膜中的一种。
作为本发明的更进一步技术方案:所述空白区的宽度为3mm。
作为本发明的更进一步技术方案:所述胶水层为高粘型丙烯酸胶水,胶水层的厚度为20-30μm。
作为本发明的更进一步技术方案:所述离型纸为双塑单硅离型纸,离型纸的离型力20-30克。
作为本发明的更进一步技术方案:所述可打印纸张的重量为每平米80克-350克,可打印膜类的厚度为1丝-30丝。
一种适用于数码打印的不干胶材料的生产工艺,包括以下步骤:
步骤一:离型纸裁切:对外购的离型纸检查其质量是否符合生产要求,将符合生产要求的成卷的离型纸裁切为合适的尺寸;
步骤二:制作网版:根据所需尺寸制作网版,网版包括边框,边框内侧为丝网,丝网的四周涂覆用于封网的感光胶,形成封网部,感光胶内侧为漏胶丝网,形成漏胶部,漏胶部的长度和宽度均小于离型纸的长度和宽度;
步骤三:涂胶:选择刮刀涂布方式,使用刮刀涂胶装置,将离型纸放置于刮刀涂胶装置上,离型纸上方为可升降的网版,在网版一侧的感光胶上倒入水性压敏胶,网版下降至离型纸处,刮刀涂胶装置的刮刀和回胶刀同时从网版一侧移动至另一侧,刮刀接触网版,回胶刀不接触网版,则刮刀将水性压敏胶透过漏胶部涂至离型纸上,涂覆胶水的长度和宽度均小于离型纸的长度和宽度;
步骤四:干燥:涂覆完胶水的离型纸通过隧道烘干系统烘干,烘干的温度为100℃,烘干时间为1-2分钟;
步骤五:复合和成片裁切:在胶水层上覆一层可打印面层。
本发明的有益效果:
本发明离型纸四周没有胶水层,为空白区,可打印面层四周没有胶水层,为空白区,胶水层未涂覆满整个离型纸和可打印面层,当将可打印面层放置在激光打印机或喷墨打印机中进行打印图文时,即使有热压作用,涂在可打印面层和离型纸之间的胶层即使有熔漏,也仅仅流到大于胶层的可打印面层与离型纸的中间空白区,阻止了胶液沾污到激光打印机硒鼓、定影器和喷墨打印机的进纸组件或进纸单元,保护了激光打印机的硒鼓、定影器和喷墨打印机的进纸组件或进纸单元,提高了这些办公印刷设备的使用寿命,从而保证了批量印刷的品质。

7.根据权利要求6所述的一种适用于数码打印的不干胶材料,其特征在于:所述可打印纸张的重量为每平米80克-250克,可打印膜类的厚度为1丝-30丝。
8.一种适用于数码打印的不干胶材料的生产工艺,其特征在于:包括以下步骤:
步骤一:离型纸裁切:对外购的离型纸(1)检查其质量是否符合生产要求,将符合生产要求的成卷的离型纸(1)裁切为合适的尺寸;
步骤二:制作网版(5):根据所需尺寸制作网版(5),网版(5)包括边框(51),边框(51)内侧为丝网,丝网的四周涂覆用于封网的感光胶,形成封网部(52),感光胶内侧为漏胶丝网,形成漏胶部(53),漏胶部(53)的长度和宽度均小于离型纸(1)的长度和宽度;
步骤三:涂胶:选择刮刀涂布方式,使用刮刀涂胶装置,将离型纸(1)放置于刮刀涂胶装置上,离型纸(1)上方为可升降的网版(5),在网版(5)一侧的感光胶上倒入水性压敏胶,网版(5)下降至离型纸(1)处,刮刀涂胶装置的刮刀和回胶刀同时从网版(5)一侧移动至另一侧,刮刀接触网版(5),回胶刀不接触网版(5),则刮刀将水性压敏胶透过漏胶部(53)涂至离型纸(1)上,涂覆胶水的长度和宽度均小于离型纸(1)的长度和宽度;
步骤四:干燥:涂覆完胶水的离型纸(1)通过遂道烘干系统烘干,烘干的温度为100℃,烘干时间为1-2分钟;
步骤五:通过复合机把烘干涂有胶水的离型纸与可打印数码印刷纸张或可打印膜进行复合成卷。
9.步骤六:把复合好的卷材通过定位裁切机进行切张,裁片。
