Abstract

一种树脂浸渍装饰板用装饰纸，具备原纸(6)、设置于原纸(6)的表面(6a)侧的花纹纹理层(7)、以及配置于花纹纹理层(7)的表面(7a)上或花纹纹理层(7)中的发泡剂(8)。并且，发泡剂(8)在发泡后的平均粒径设为15μm以上250μm以下，发泡起始温度设为100℃以上220℃以下。

Description

树脂浸渍装饰板用装饰纸、树脂浸渍装饰纸及树脂浸渍装 饰板
技术领域
本发明涉及树脂浸渍装饰板用装饰纸、树脂浸渍装饰纸及树脂浸渍装饰板。
背景技术
以往，提出了一种树脂浸渍装饰板的制造方法，其中，将金属板抵接于浸渍有热固性树脂的树脂浸渍装饰纸与基材的层叠体上并进行加热加压成型，从而获得树脂浸渍装饰纸与木质基材一体化而成的树脂浸渍装饰板(例如参照专利文献1)。
在专利文献1所记载的树脂浸渍装饰板的制造方法中，在金属板上设置压花形状以对树脂浸渍装饰板的表面赋予凹凸纹理，从而赋予手的触感。另外，也可以通过调整压花形状的粗密度以赋予总体哑光效果(gross matt expression)。
但是，在专利文献1所记载的树脂浸渍装饰板的制造方法中，由于必须为每个想要赋予的凹凸纹理准备金属板，因此可能会增加成本。

另外，本发明的另一方面的要点在于一种树脂浸渍装饰纸，其具备：(a)上述树脂浸渍装饰板用装饰纸、以及(b)浸渍于树脂浸渍装饰板用装饰纸中的热固性树脂。
此外，本发明的另一方面的要点在于一种树脂浸渍装饰板，其具备：(a)上述树脂浸渍装饰纸、以及(b)与树脂浸渍装饰纸一体化的基材。
发明的效果
根据本发明的一个方面，由于将发泡剂在发泡后的平均粒径及发泡起始温度设为适当的数值，因此通过以往的树脂浸渍装饰板的制造方法，可以在加热加压成型时使发泡剂发泡，并且可以在树脂浸渍装饰板的表面上适当地形成凹凸纹理。由此，可以使树脂浸渍装饰板表现出总体哑光效果及手触感。此外，通过调整树脂浸渍装饰板用装饰纸中的发泡剂的配置位置，从而可以对树脂浸渍装饰板的表面赋予任意的凹凸纹理，并且不需要为每种凹凸纹理准备金属板。因此，可以提供在抑制成本的同时还能够形成总体哑光效果及手触感优异的树脂浸渍装饰板的树脂浸渍装饰板用装饰纸、树脂浸渍装饰纸以及树脂浸渍装饰板。

具体实施方式
以下，对于根据本发明实施方式的树脂浸渍装饰板用装饰纸、树脂浸渍装饰纸以及树脂浸渍装饰板，参照附图来进行说明。本发明不限于以下所记载的实施方式，可以基于本领域技术人员的知识来进行设计的改变等修改，进行了这样的修改后的实施方式也包括在本发明的范围内。另外，为了便于理解，适当夸张地显示了各附图。
(构成)
如图1所示，根据本发明实施方式的树脂浸渍装饰板1是通过对树脂浸渍装饰纸2与基材3的层叠体进行加热加压成型以使树脂浸渍装饰纸2与基体3一体化而成的装饰板。即，树脂浸渍装饰板1具备：基材3、以及设置在基材3的表面3a侧的树脂浸渍装饰纸2。根据本发明实施方式的树脂浸渍装饰板1是用于(例如)建筑物的地板、墙壁、天花板等室内装饰；家具、各种橱柜等的表面装饰材料；门窗的表面装饰；车辆内部装饰等的树脂浸渍装饰板。
(基材)
基材3的种类没有特别的限定，可以根据作为目标的树脂浸渍装饰板1的用途而使用任意的基材。例如，可以采用单木板、胶合板、层压材料、刨花板、中密度纤维板、硬质纤维板等木质基材；纸板、织布、无纺布、树脂浸渍纸、树脂浸渍布等纤维质基材；石膏板、板岩板、硅酸钙板、矿渣石膏板、木棉水泥板、矿渣水泥板、轻质泡沫混凝土板、玻璃纤维增强混凝土板等无机质基材；钢板、黄铜板、铝板、硬铝板、不锈钢板等金属基材；丙烯酸类树脂板、苯乙烯树脂板、ABS(Acrylonitrile butadiene styrene，丙烯腈丁二烯苯乙烯)树脂板、聚碳酸酯树脂板、尼龙树脂板、聚苯乙烯树脂板、聚丙烯树脂板、聚酯树脂板、玻璃纤维增强塑料板等合成树脂基材等；或者选自它们的2种以上的复合体或层叠体等。
(树脂浸渍装饰板用装饰纸)
根据本发明实施方式的树脂浸渍装饰纸2是通过使热固性树脂5浸渍于树脂浸渍装饰板用装饰纸4中、然后使树脂浸渍装饰板用装饰纸4干燥而得的装饰纸。树脂浸渍装饰板用装饰纸4具备：原纸6、设置在原纸6的表面6a侧的花纹纹理层7、以及配置在花纹纹理层7的表面7a上或花纹纹理层7中的发泡剂8。
需要说明的是，图1示出了在花纹纹理层7的表面7a上配置有发泡剂8的一个例子。
(原纸)
作为原纸6，可以使用能够浸渍热固性树脂5的吸水性良好的纸等纤维质片状体。例如，可以采用薄叶纸、钛纸、上等纸、漂白或未漂白的牛皮纸等。特别地，若考虑到印刷适应性和树脂浸渍适应性这两方面，则钛纸是最合适的。另外，在利用基材3的表面3a的质感的情况下，优选使用具有通过热固性树脂5的浸渍而变得透明的性质的所谓的透明纸。原纸6的厚度没有特别的限制，但优选在单位面积重量为20g/m2以上200g/m2以下的范围内。
(花纹纹理层)
花纹纹理层7是用于对树脂浸渍装饰纸2赋予由花纹纹理带来的设计性的层。花纹纹理层7通过使用印刷油墨等来形成，该印刷油墨是通过将染料或颜料等着色剂与适当的粘合剂树脂一起溶解或分散在稀释溶剂中而得的。印刷油墨的种类没有特别的限定，可以是油性油墨，也可以是水性油墨。即，作为印刷油墨，可以使用不具有疏液性的普通印刷油墨。
特别地，考虑到热固性树脂浸渍适应性，水性油墨是最合适的。与油性油墨相比，水性油墨与浸渍树脂的水溶液具有更好的相容性。因此，当使用水性油墨时，在制造树脂浸渍装饰板1时的浸渍步骤中，可以使浸渍树脂迅速且均匀地浸渍于树脂浸渍装饰板用装饰纸4中，此外，可以通过与浸渍树脂的一体化而在优异的花纹纹理层7中展现出强度。水性油墨的种类没有特别的限制，但优选为包含以酪蛋白、乳化树脂作为主成分的粘合剂树脂的油墨。
这样的粘合剂树脂具有在印刷油墨后经过干燥步骤而变得难溶于水的性质。因此，当使用包含这样的粘合剂树脂的粘合剂树脂时，在制造树脂浸渍装饰板1时的树脂浸渍步骤中，花纹纹理层7难以再次溶解于浸渍树脂的水溶液中，从而可以保持花纹纹理，进而可以防止浸渍树脂的污染。
作为乳液树脂，例如可以采用丙烯酸类、乙酸乙烯酯类、苯乙烯类、氨基甲酸酯类等。另外，在粘合剂树脂中，除了酪蛋白、乳液树脂以外，还可以一起使用(例如)聚乙烯醇、聚丙烯酰胺等水溶性树脂、以及多糖类、纤维素衍生物等水溶性高分子等以提高油墨的稳定性。
花纹纹理层7的形成方法没有特别的限定，例如可以使用凹版印刷法、胶版印刷法、丝网印刷法、柔版印刷法、凸版印刷法、喷墨印刷法等任意的印刷方法。另外，在花纹纹理层7与原纸6的层间，可以设置用于使基底着色的实地油墨层，当设置实地油墨层时，作为实地油墨层的形成方法，除了上述各种印刷方法以外，还可以使用(例如)辊涂法、凹版涂布法、棒涂法、刮刀涂布法、气刀涂布法、喷涂法、唇涂法、模涂法等任意的涂布方法。
花纹纹理层7所形成的花纹的种类没有特别的限定，可以根据作为目标的树脂浸渍装饰板1的用途来使用任意的花纹。例如，可以采用木纹图案、石纹图案、布料图案、抽象图案、几何图形、字符、符号、纯色等；或者选自它们中的2种以上的组合等。
(发泡剂)
发泡剂8是用于通过树脂浸渍装饰纸2的表面的凹凸纹理9来赋予总体哑光效果及手触感的层。发泡剂8的种类没有特别的限定，可以使用任意的发泡剂。例如，可以采用偶氮二羧酸酰胺、偶氮二甲酰胺等偶氮类，氧苯磺酰肼、对甲苯磺酰肼等酰肼类等热分解型的化学发泡剂；微囊发泡剂等。
特别地，微囊发泡剂是最合适的。微囊发泡剂具有囊体、以及封装在该囊体中的挥发性物质。然后，通过使挥发性物质挥发以使囊体膨胀，使得微囊发泡剂成为发泡状态。作为囊体的材料，可以使用(例如)偏二氯乙烯-丙烯腈共聚物等。此外，作为挥发性物质的材料，可以使用(例如)脂肪族烃等。
优选的是，发泡剂8在发泡前的平均粒径为花纹纹理层7的层厚的2/3倍以上50倍以下。若小于花纹纹理层7的层厚的2/3倍，则总体哑光效果及手触感可能会变弱。另一方面，若大于花纹纹理层7的层厚的50倍，则发泡后的发泡剂8可能会从树脂浸渍装饰板用装饰纸4上掉落等，耐擦伤性可能减弱。在此，平均粒径是通过显微镜观察得到的平均粒径。通过显微镜观察得到的平均粒径可以通过(例如)在显微镜下观察发泡剂8并采用图像处理软件等测定100个由显微镜观察得到的发泡剂8的粒径、然后以个数为基准对测定结果进行平均而得。需要说明的是，作为发泡剂8的粒径，可以采用发泡剂8的颗粒的长径和短径的平均值。
优选的是，发泡剂8在发泡后的平均粒径为15μm以上250μm以下。若小于15μm，则总体哑光效果及手触感可能会变弱。另一方面，若大于250μm，则发泡后的发泡剂8可能会从树脂浸渍装饰板用装饰纸4上掉落等，耐擦伤性可能减弱。更优选为30μm以上200μm以下。在此，与发泡前的发泡剂8的平均粒径同样地，发泡后的发泡剂8的平均粒径也是通过显微镜观察得到的平均粒径。另外，作为用于获得平均粒径的发泡后的发泡剂8的粒径，可以采用通过发泡剂8的发泡而形成的空隙的长径和短径的平均值。
此外，发泡剂8的发泡起始温度优选为100℃以上220℃以下。若低于100℃，则开始发泡的时间点较早，因此发泡后的发泡剂8被加热加压的时间变长，发泡后的发泡剂8可能被压碎，总体哑光感及手触感可能会变弱。另一方面，若高于220℃时，则在树脂浸渍装饰板1的制造过程中，由于通过与金属板(镜面板)抵接而进行的加热加压成型，使得发泡剂8不能充分地发泡，总体哑光感及手触感可能会变弱。更优选为120℃以上200℃以下。
发泡后的发泡剂8所形成的凹凸纹理9的种类没有特别的限制，可以与花纹纹理层7所形成的花纹设计性地同步，也可以不同步。特别地，若考虑到获得设计性优异的树脂浸渍装饰板1，则最优选的是与花纹纹理层7所形成的花纹设计性地同步。当使花纹纹理层7所形成的花纹与凹凸纹理9设计性地同步时，使发泡剂8的配置位置与花纹纹理层7所形成的花纹同步。即，在花纹纹理层7所形成的花纹当中，将发泡剂8配置在想要表现出消光状质感的部位上。例如，将发泡剂8配置在花纹纹理层7的表面上，以覆盖花纹纹理层7所形成的花纹当中的、亮度相对于该花纹的其他部分而言更低的暗色部分。由发泡剂8覆盖的面积在暗色部分的面积中所占有的比率优选为70％以上。特别地，最优选为90％以上。当将花纹纹理层7的花纹设为木纹理时，将发泡剂8配置成与花纹纹理层7的木纹理设计性地同步的导管纹理状。发泡剂8的颜色没有特别的限定，可以是无色的，也可以是有色的。
需要说明的是，当将发泡剂8配置在花纹纹理层7中时，将发泡剂8配置在花纹纹理层7中，并且混入至花纹纹理层7所形成的花纹当中的、亮度相对于该花纹的其他部分而言更低的暗色部分中。发泡剂8的体积在暗色部分的体积与发泡剂8的体积的总体积中所占的比率优选为70％以上。特别地，最优选为90％以上。
发泡剂8的配置方法没有特别的限定，例如可以采用在花纹纹理层7上印刷通过将发泡剂8与适当的粘合剂树脂一起分散在稀释溶剂中而得的印刷油墨的方法。作为粘合剂树脂，可以使用(例如)2液固化型氨基甲酸酯树脂等具有氨基甲酸酯键的热固化型树脂；电离放射线固化性树脂等固化性树脂；以酪蛋白、乳液树脂为主成分的树脂。作为热固化型树脂，可以采用(例如)三聚氰胺系树脂、环氧系树脂、尿素系树脂、酚系树脂、不饱和聚酯系树脂、邻苯二甲酸二烯丙基酯系树脂、苯并胍胺系树脂、氨基甲酸酯系树脂、氨基醇酸系树脂、有机硅系树脂等。另外，作为电离放射线固化性树脂，例如可以采用(甲基)丙烯酸酯系树脂、不饱和聚酯系树脂等。
另外，与花纹纹理层7同样地，发泡剂8的印刷油墨的印刷方法没有特别的限定，可以使用(例如)凹版印刷法、胶版印刷法、丝网印刷法、柔版印刷法、凸版印刷法、喷墨印刷法等任意的印刷方法。
(树脂浸渍装饰板的制造方法)
接下来，对根据本发明实施方式的树脂浸渍装饰板1的制造方法进行说明。
首先，将树脂浸渍装饰板用装饰纸4浸渍于通过使热固性树脂5溶解或分散在水中而得的水系浸渍液中，从而使树脂浸渍装饰板用装饰纸4中浸渍有热固性树脂5。
作为热固性树脂5，可以使用在树脂浸渍装饰板的制造时所使用的公知的热固性树脂。例如，可以采用三聚氰胺系树脂、环氧系树脂、邻苯二甲酸二烯丙基酯系树脂、苯并胍胺系树脂、氨基甲酸酯系树脂、醇酸系树脂、不饱和聚酯系树脂、酚系树脂、尿素系树脂等。热固性树脂5的浸渍可以从树脂浸渍装饰板用装饰纸4的形成有花纹纹理层7或发泡剂8的表面侧开始进行，也可以从相对面的那一侧开始进行。此外，可以分两次地逐个对单个表面进行浸渍，也可以同时对两个表面进行浸渍。热固性树脂5的浸渍率(浸渍树脂的质量在浸渍后的树脂浸渍装饰板用装饰纸4的质量中所占的比率)优选为20％以上80％以下。特别地，最优选为40％以上70％以下。此外，为了获得物理性能优异的树脂浸渍装饰板1，重要的是使热固性树脂5均匀地浸渍整个原纸6。
接下来，将浸渍有热固性树脂5的树脂浸渍装饰板用装饰纸4干燥，从而得到树脂浸渍装饰纸2。随后，将树脂浸渍装饰纸2放置在基材3上，使金属板(镜面板)与树脂浸渍装饰纸2的表面2a抵接，对树脂浸渍装饰纸2与基材3的层叠体进行加热加压成型以使树脂浸渍装饰纸2与基材3一体化，从而获得树脂浸渍装饰板1。此时，发泡剂8通过加热加压成型时的热量而发泡，树脂浸渍装饰板1的表面的配置有发泡剂8的位置鼓起而形成凹凸纹理9。然后，通过所形成的凹凸纹理9，从而使树脂浸渍装饰板1展现出总体哑光感及手触感。
需要说明的是，在基材3与树脂浸渍装饰纸2之间可以隔着粘接剂等，也可以不隔着粘接剂等。此外，根据需要，与公知的三聚氰胺树脂装饰板所采用的方法同样地，也可以插入芯纸。作为芯纸，可以使用(例如)通过将未固化状态的热固性树脂浸渍于钛纸、漂白或未漂白的牛皮纸、玻璃纤维无纺布等适当的原纸而得的材料。另外，热固性树脂可以根据作为目标的树脂浸渍装饰板1所要求的物性等而使用任意的热固性树脂。例如，可以采用三聚氰胺系树脂、环氧系树脂、邻苯二甲酸二烯丙基酯系树脂、苯并胍胺系树脂、氨基甲酸酯系树脂、醇酸系树脂、不饱和聚酯系树脂、酚系树脂、尿素系树脂等。作为芯纸的例子，可列举出以往已被广泛用作三聚氰胺树脂装饰板的芯纸的酚系树脂浸渍牛皮纸。
作为用于在层叠的状态下将树脂浸渍装饰纸2粘接在基材3上的加热加压成型方法，可以使用(例如)将金属板抵接以进行平压加压的方法、圆压式的连续层压方式等。特别地，优选使用金属制环形带的连续层压方式。通过连续层压方式，可以高速且连续地制造表面没有翘曲或起伏等、并且层间密合性良好且致密地固化并一体化的高品质树脂浸渍装饰板1。
当使用连续层压方式时，树脂浸渍装饰板1的表面形状成为在连续层压方式中使用的金属板或金属制环形带、由固化型树脂等制作的压花片的表面形状直接赋予的形状。因此，通过使用表面已被平滑地研磨成镜面状等的材料作为金属板或金属制环形带、由固化型树脂等制作的压花片，从而可以获得表面光泽度及平滑性优异的树脂浸渍装饰板1。
当然，根据需要，通过使用所需的任意的消光状或质地状的金属板或金属制环形带、由固化型树脂等制作的压花片，从而也能够根据作为目标的树脂浸渍装饰板1的用途而获得任意的表面为成品状态的树脂浸渍装饰板1。
本发明的树脂浸渍装饰板1不限于上述详细说明的实施方式，在不脱离本发明主旨的范围内，也可以进行各种变形后实施。
如上所述，根据本发明实施方式的树脂浸渍装饰板用装饰纸4具备：原纸6、设置在原纸6的表面6a侧的花纹纹理层7、以及配置在花纹纹理层7的表面7a上或花纹纹理层7中的发泡剂8。并且，发泡剂8在发泡后的平均粒径设为15μm以上250μm以下，发泡起始温度设为100℃以上220℃以下。因此，由于将发泡剂8在发泡后的平均粒径以及发泡起始温度设为适当的数值，因此通过以往的树脂浸渍装饰板的制造方法，可以在加热加压成型时使发泡剂8发泡，可以在树脂浸渍装饰板1的表面上适当地形成凹凸纹理9。由此，可以使树脂浸渍装饰板1展现出总体哑光感及手触感。另外，通过调整发泡剂8在树脂浸渍装饰板用装饰纸4中的配置位置，从而可以在树脂浸渍装饰板1的表面上赋予任意的凹凸纹理9，而不需要为每种凹凸纹理9准备金属板。因此，可以提供在抑制成本的同时还能够形成总体哑光效果及手触感优异的树脂浸渍装饰板1的树脂浸渍装饰板用装饰纸4。
另外，由于发泡剂8在发泡后的平均粒径为15μm以上250μm以下，并且发泡剂8的发泡起始温度为100℃以上220℃以下，因此可以形成适当的凹凸纹理9，可以提供总体哑光感、手触感及耐擦伤性优异的树脂浸渍装饰板用装饰纸4。
此外，在根据本发明实施方式的树脂浸渍装饰板用装饰纸4中，由于花纹纹理层7所形成的花纹与发泡剂8的配置位置同步，因此可以形成花纹纹理层7所形成的花纹与树脂浸渍装饰板1表面的凹凸纹理9设计性地同步的树脂浸渍装饰板1。
另外，在根据本发明实施方式的树脂浸渍装饰板用装饰纸4中，发泡剂8在发泡前的平均粒径为花纹纹理层7的层厚的2/3倍以上50倍以下。因此，可以形成适当的凹凸纹理9，可以提供总体哑光感、手触感及耐擦伤性优异的树脂浸渍装饰板1。
此外，将根据本发明实施方式的树脂浸渍装饰纸2设为具备：树脂浸渍装饰板用装饰纸4、以及浸渍于树脂浸渍装饰板用装饰纸4中的热固性树脂5。因此，可以提供在抑制成本的同时还能够形成总体哑光效果及手触感优异的树脂浸渍装饰板1的树脂浸渍装饰纸2。
另外，将根据本发明实施方式的树脂浸渍装饰板1设为具备：树脂浸渍装饰纸2、以及与树脂浸渍装饰纸2一体化的基材3。因此，可以提供在抑制成本的同时总体哑光效果及手触感也优异的树脂浸渍装饰板1。

Figure BDA0002795624810000141
如表1所示，对于实施例1～9的树脂浸渍装饰板1，总体哑光效果试验、手触感试验以及耐擦伤性试验为“◎”以上。另一方面，对于比较例1～8的树脂浸渍装饰板1，总体哑光效果试验、手触感试验以及耐擦伤性试验中的任一项为“△”以下。
具体而言，比较例1、2的树脂浸渍装饰板1由于使用了发泡后的平均粒径小的发泡剂8，因此总体哑光效果及手触感变弱，总体哑光效果试验及手触感试验成为“×”。另外，比较例3、4的树脂浸渍装饰板1由于使用了发泡后的平均粒径大的发泡剂8，因此发泡后的发泡剂8发生脱落等，耐擦伤性变弱，耐擦伤性试验成为“×”。此外，比较例5、6的树脂浸渍装饰板1由于使用了发泡起始温度低的起泡剂8，因此发泡后的发泡剂8被加热加压的时间变长，发泡后的发泡剂8被压碎，总体哑光效果试验成为“△”，手触感试验成为“×”。此外，比较例7、8的树脂浸渍装饰板1由于使用了发泡起始温度高的起泡剂8，因此发泡剂8在加热加压成型时没有充分地发泡，总体哑光效果试验及手触感试验成为“△”。
与此相对，实施例1～9的树脂浸渍装饰板1中，由于发泡剂8在发泡后的平均粒径以及发泡剂8的发泡起始温度为适当的数值，因此发泡剂8在加热加压成型时适当地发泡，总体哑光效果试验及手触感试验成为“◎”，耐擦伤性试验成为“○”。
因此，可以确认，与比较例1～8的树脂浸渍装饰板1相比，实施例1～9的树脂浸渍装饰板1的总体哑光效果、手触感以及耐擦伤性更加良好。
