Abstract

一种装饰性原纸或预浸渍装饰性原纸,具有一油墨吸收层,用喷墨方法印刷。

Description

具有喷墨吸收层的装饰性原纸
本发明涉及一种可以通过喷墨印刷方法印刷的装饰性原纸或用于装饰性涂层材料的预浸渍装饰性原纸，尤其是薄膜原纸和印刷原纸。
在制造装饰性层压制品、装饰性薄膜和预浸渍片时需要用装饰性原纸。装饰性涂层材料用于家具制造和内部装饰的表面涂覆。
不同的应用需要不同的纸张定量的装饰性原纸。边饰装饰性原纸具有平均纸张定量为200g/m2。然而，用于表面涂饰的装饰性原纸的纸张定量是在20到200g/m2的范围内的。也需要纸张定量为15到40g/m2的贴面原纸。它还在贴面原纸、装饰性纸、阻挡纸和纤维板的复合层压制品中用作覆盖材料。
传统的薄膜原纸或预浸渍片被印刷上需要的图案，由丙烯酸酯-脲聚合物浸渍，然后将其粘合在基材上。印刷图案通过凹版印刷的方法来印刷。这导致了高的油墨消耗量，并且图像清晰度经常因墨点缺失而不足。制造少量的印刷材料时非常复杂且昂贵的。
通过预浸渍，装饰性原纸在造纸机上制造时进行浸渍。印刷之后，涂覆被印刷表面并将预浸渍片的背面粘合到基材上。预浸渍片的纸张定量为20到100g/m2。
DE19503745C1描述了优选用于涂覆比赛记分板的薄膜原纸的特定形式。
喷墨印刷方法自从80年代起就已经为人所知了。虽然自80年代末以来应用这项技术使照相品质印刷变为了可能，但是上面提到的凹版印刷的方法仍被应用于印刷装饰性原纸。
本发明的目的在于获得一种具有好的印刷性能的装饰性原纸，以使其可以通过喷墨印刷方法来印刷，该原纸还具有低油墨消耗量，好的图像清晰度和高的色彩浓度。
该目的通过应用基于装饰性原纸的涂层材料来获得，其上已经创建了一油墨吸收层。特别的是，这种基于装饰性原纸的涂层材料是薄膜原纸或印刷原纸。因此根据本发明的薄膜原纸是带有油墨吸收层的预浸渍的装饰性原纸。根据本发明的印刷原纸是带有油墨吸收层的未浸渍的装饰性原纸。
装饰性原纸与用于彩印、制图和照相品质打印输出的普通喷墨纸的不同主要在于它们的性能。这些纸具有合成树脂涂层或浇铸涂层制成的闭合表面。在涂覆油墨吸收层之后，载体和涂层之间具有一个清晰的分界。
另一方面，装饰性原纸具有一个开放表面以使装饰性原纸可以迅速并且均匀地被浸渍树脂浸渍。因此，传统的装饰性原纸不适合于涂覆油墨吸收层，因为在装饰性原纸的表面上形成一个均匀厚度的油墨吸收层是不可能的。
根据本发明的一个实施方案，装饰性原纸是其一个表面是光滑的、在印刷前预浸渍的并且在其光滑表面上涂覆一油墨吸收层的装饰性原纸。具有一个光滑表面的装饰性原纸优选地在单烘缸造纸机上制造，在那里纸幅的网面在加热缸的帮助下变得光滑了。由于纸与缸长时间的接触，制造一种防潮的光滑表面是可能的。预浸渍在造纸机上完成，其中浸渍剂为纸浆重量的5到30％。
根据本发明的另一个实施方案，所用的装饰性原纸是在软轧光机上变得光滑的。油墨吸收层涂覆在光滑面上。
合适的浸渍剂包括通常用于本技术领域的浸渍树脂，尤其是蜜胺-甲醛树脂，脲-甲醛树脂、酚甲醛树脂、尿酸-丙烯酸酯共聚物或聚乙烯醇。
为了达到足够的树脂吸收和同时阻止油墨吸收层沉没到纸中，一个表面光滑的装饰性原纸的透气度按照Gurley必须等于3到20秒。按照BeKK平滑度必须不高于50BeKK秒。用软轧光机使其光滑的装饰性原纸的透气度等于20到40Gurley秒，尤其是30到40Gurley秒。这种原纸的平滑度等于至少50BeKK秒。
本发明装饰性原纸的纸张定量在15到400g/m2的范围内，例如等于15到40g/m2或20到200g/m2。纸张定量被选为本特定申请的函数。
为了制造这些不同的装饰性原纸，可以应用针叶木浆(长纤维木浆)或阔叶木纤维素(短纤维木浆)。优选的是比例为10∶90到90∶10的针叶木浆和阔叶木浆混合物。特别优选的是比例为30∶70到70∶30的针叶木浆和阔叶木浆混合物。按照Schopper-Riegler，木浆可以具有20°到60°SR的打浆程度。为了达高的不透明度，可以加入如二氧化钛或碳酸钙等颜料。基于木浆的重量，颜料的量可以为10到40％(重量)。
另外，湿强度剂如聚酰胺/聚胺-环氧氯丙烷树脂，阳离子聚丙烯酸酯，改性三聚氰氨-甲醛树脂或阳离子淀粉可以被加入到用于生产装饰性原纸的木浆悬浮液中去。同样地，还可能加入助留剂和着色剂。
该片材可以在单烘缸造纸机或长网造纸机上形成。
所有的已知的吸收层都可以用作油墨吸收层。它们通常是亲水涂层，这些亲水涂层包含水溶性或水分散性的聚合物，如聚乙烯醇，阳离子聚乙烯醇，聚乙烯基吡咯烷酮，聚醋酸乙烯酯，淀粉，明胶，酪蛋白或羧甲基纤维素。油墨吸收层还可以包含颜料和使油墨颜料定色的阳离子物质。在德国专利4322179和4322178中和德国专利申请19604693和19618607中，对适用于本发明的油墨吸收层进行了描述，该公开在此并入作为参考。优选的是包含颜料的油墨吸收层。
油墨吸收层的施用量为2到20g/m2，尤其是5到15g/m2。油墨吸收层可以用常见施用方法如辊混，凹涂或nipp方法和喷枪或辊刮刀供料来应用。
本发明在下面实施例的基础上进行较详尽描述。
