Abstract

本发明的目标是提供一种用于管乐器的木质材料，其对湿气改变有优越的抵抗性。用于管乐器的木质材料包括：经层积的多个单板；和至少一个缓冲层，包括用无纺织物或纺织织物构成的纤维片，和对纤维片进行浸渍的粘接剂，缓冲层插置在多个单板中的相邻两个单板之间。

Description

管乐器木质材料、管乐器和管乐器木质材料的制造方法
背景技术
本发明涉及用于管乐器的木质材料、管乐器和用于管乐器的木质材料的制造方法。
技术领域
通过将木材切削为管状形状而制造的管乐器(例如双簧管和单簧管)是已知的。用于这种管乐器的材料通常是相对罕见的且因此很昂贵，且一件材料和一件材料之间的品质差异是相对显著。
在这方面，作为用于管乐器的木质材料，已经提出使用通过粘接剂将单板(即从木材切出的薄板)层积而获得的单板层积材(laminated veneer lumber：LVL)(例如见日本未审查专利申请公开No.2010-184420)。单板层积材是相对地不贵的，因为除了有木节或裂缝以外的大部分天然木材都可用作原材料。由于通过将大量单板进行层积而对木材原料中的品质差异进行了补偿，所以单板层积材的另一优势是具有相对稳定的品质。
上述文献公开了包含在粘接剂中的环氧树脂对高强度、高声速和低振动阻尼系数(tanδ)有贡献，且由于对湿气的吸收和解吸收作用，还对木材固有的尺寸变化的减小有贡献。应注意，对于作为对天然木材的替换的用于管乐器的木质材料的振动特性，鉴于需要实现与更高等级天然木材的振动特性类似的振动特性，据报道期望的是相对高的声速和相对低的振动阻尼系数。
用于上述文献公开的管乐器的木质材料(其中单板的扩张和收缩被粘接剂所抑制)具有的缺点是，在单板由于湿气吸收和干燥而膨胀和收缩时，应力会集中在单板和粘接剂之间的界面处，且因此可能发生层间分离，作为对因湿气改变而造成的尺寸变化进行降低的权宜之计。

发明内容
有鉴于上述缺点，本发明的目标是提供一种用于管乐器的木质材料和管乐器，其对湿气改变有优越的抵抗性，以及提供用于管乐器的木质材料的制造方法。
根据用于解决上述问题的本发明的一个方面，用于管乐器的木质材料包括：经层积的多个单板；和至少一个缓冲层，包括用无纺织物或纺织织物构成的纤维片、和对纤维片进行浸渍的粘接剂，缓冲层插置在多个单板中的相邻两个单板之间。
纤维片可以用合成纤维构成的无纺织物。
缓冲层的平均厚度优选不小于0.05mm且不大于0.20mm。
单板的平均厚度优选不小于0.5mm且不大于5mm。
纤维片的纤维的主要成分可以是聚酯、聚酰胺、丙烯酸树脂、聚乙烯、或聚丙烯。
缓冲层中粘接剂的主要成分可以是环氧树脂、酚醛树脂、尿烷树脂、或丙烯酸树脂。
纤维片的纤维的主要成分可以是聚酯，且粘接剂的主要成分可以是环氧树脂。
缓冲层中粘接剂的百分含量优选为按质量不小于40％且按质量不大于90％。
根据用于解决上述问题的本发明的另一方面，管乐器用木质材料形成，所述木质材料包括：多个单板；和至少一个缓冲层，包括用无纺织物或纺织织物构成的纤维片，和对纤维片进行浸渍的粘接剂，缓冲层插置在多个单板中的相邻两个单板之间。
根据用于解决上述问题的本发明的另一方面，用于管乐器的木质材料的制造方法包括：用树脂组合物浸渍单板；用粘接剂浸渍由无纺织物或纺织织物构成的纤维片；将用粘接剂浸渍的纤维片和单板每一个交替地层积；和使得已经对单板进行浸渍的树脂组合物和已经对纤维片进行浸渍的粘接剂硬化。
应注意，术语“主要成分”是指按质量百分含量最大的成分，且优选是按质量百分含量不小于按质量50％的成分。
附图说明
图1是显示了根据本发明实施例的用于管乐器的木质材料的分层结构的示意性横截面图；
图2是根据本发明另一实施例的单簧管的正视图；和
图3是沿图2所示的单簧管的A-A线截取的端部视图。
具体实施方式
适当参考附图，将在下文详细描述本发明的实施例。
用于管乐器的木质材料
根据图1所示的本发明实施例的用于管乐器的木质材料被用作用于例如单簧管、双簧管、低音管和八孔竖笛这样的管乐器的材料，这种管乐器通过用木材形成的共鸣器而产生声音。
用于管乐器的木质材料包括层积的多个单板1，和插置在多个单板1中相邻两个单板之间的至少一个缓冲层2。
单板
单板1是从天然木材切出的薄板。单板1的材料(木材类型)取决于要由用于管乐器的木质材料所制造的乐器类型等，但是例如可以是非洲黑木(grenadilla)、桦木、云杉、枫木、橡木、梅兰蒂木(metanti)、日本光腊木、白扬木、花梨木(bubinga)、桃花心木、光叶榉木、冰片香木(kapur)、日本山毛榉木等。这些木材中，桦木、云杉、日本光腊木和橡木是尤其优选的。多个单板1相对于彼此可以具有材料不同。
单板1的平均厚度下限优选为0.5mm且更优选为0.7mm。同时，单板1的平均厚度上限优选为5mm且更优选3mm。在单板1的平均厚度小于下限时，由于用于管乐器的木质材料的振动特性与天然木材的振动特性不同，由用于管乐器的木质材料形成的管乐器的乐音会不自然。另一方面，在单板1的平均厚度大于上限时，天然木材的品质改变会得不到充分补偿。
此外，单板1可以被树脂组合物(resin composition)浸渍。被树脂组合物浸渍的单板1使得单板1被强化，且允许使用相对不贵的木材。
用于浸渍单板1的树脂组合物的主要成分可以例如是环氧树脂、酚醛树脂等。其中，环氧树脂因为与缓冲层2连接相对容易而适宜使用。
在单板1被树脂组合物浸渍的情况下，单板1中树脂组合物的含量下限优选为按质量10％，更优选为按质量20％。同时，单板1中树脂组合物的含量的上限优选为按质量80％，更优选为按质量70％。在单板1中树脂组合物的含量小于下限时，单板不会被充分强化。另一方面，在单板1中树脂组合物的含量大于上限时，由于用于管乐器的木质材料和天然木材之间的振动特性差异增加，所以由用于管乐器的木质材料形成的管乐器的乐音会不自然。
缓冲层
缓冲层2包括纤维片(fibrous sheet)和对纤维片进行浸渍的粘接剂。
纤维片
使用纺织织物或无纺织物作为缓冲层2中的纤维片。其中，适于使用由合成纤维构成的无纺织物。通过将厚度足够的缓冲层2固定并对其提供可挠性而防止纤维片的层间分离，以由此使得缓冲层2跟随单板1的膨胀和收缩而膨胀和收缩。
也可以使用含有用于将纤维连接在一起的粘合剂的纸作为在缓冲层2中用作纤维片的无纺织物。
用于形成纤维片的纤维可以是单丝纤维或大量单丝纤维构成的多丝纤维。
可以用于形成纤维片的合成纤维的主要成分例如是聚酯、聚酰胺、丙烯酸树脂、聚乙烯、聚丙烯等。其中，聚酯是尤其优选的，因为粘接剂的选择很容易。
纤维片的平均厚度的下限(即通过纤维片限定的缓冲层2的平均厚度)优选为0.05mm且更优选为0.07mm。同时，缓冲层2的平均厚度的上限优选为0.02mm且更优选为0.16mm。在缓冲层2的平均厚度小于下限时，单板1膨胀和收缩时产生的应力不会被充分释放。另一方面，在缓冲层2的平均厚度大于上限时，由于用于管乐器的木质材料和天然木材之间的振动特性差异增加，所以由用于管乐器的木质材料形成的管乐器的乐音会不自然。
纤维片的体密度(bulk density)的下限优选为30kgm3且更优选为50kg/m3。同时，纤维片的体密度的上限优选为400kg/m3且更优选为300kg/m3。在纤维片的体密度小于下限时，在通过单板1与缓冲层2进行层积和压接而制造用于管乐器的木质材料期间，会无法保持缓冲层2的厚度。另一方面，在纤维片的体密度大于上限时：通过粘接剂进行浸渍会不充分，且因此用于管乐器的木质材料的强度会不足；和由于用于管乐器的木质材料和天然木材之间的振动特性差异增加，所以由用于管乐器的木质材料形成的管乐器的乐音会不自然。
用于形成纤维片的纤维的平均直径的下限优选为1μm且更优选为5μm。同时，用于形成纤维片的纤维的平均直径的上限优选为100μm且更优选为50μm。在用于形成纤维片的纤维的平均直径小于下限时，纤维片会变得非常昂贵才能实现例如平均厚度、体密度等的其他性能。另一方面，在用于形成纤维片的纤维的平均直径大于上限时，纤维片(进而，缓冲层2)的可挠性会不足，且因此在单板1膨胀和收缩时作用在缓冲层2上的应力不会被充分释放。应注意，术语“平均直径”是指等效圆形横截面的直径。
粘接剂
在缓冲层2中，纤维片被粘接剂浸渍，使得纤维片中的空穴被粘接剂填充，且同时，粘接剂能结合到单板1。
粘接剂优选是不含有溶剂的可固化粘接剂，且在用于管乐器的木质材料的制造过程期间伴有小量的体积改变。
粘接剂的主要成分可以例如是环氧树脂、酚醛树脂、尿烷树脂、丙烯酸树脂等。其中，环氧树脂适于使用，其可以为纤维片提供粘附性。在用树脂组合物浸渍单板1的情况下，优选的是缓冲层2中的粘接剂的主要成分是与浸渍单板1的树脂组合物的主要成分类型相同的树脂。
可以用作缓冲层2中的粘接剂的主要成分的环氧树脂例如是双酚A型环氧树脂、双酚F型环氧树脂、双酚AD型环氧树脂、酚醛型环氧树脂、联苯类环氧树脂等(biphenyl-typeepoxy resin)。
缓冲层2中粘接剂的含量下限优选为按质量40％，且更优选为按质量50％。同时，缓冲层2中粘接剂含量的上限优选为按质量90％，且更优选为按质量80％。在缓冲层2中粘接剂的含量小于下限时，粘接强度会不足。另一方面，在缓冲层2中粘接剂的含量大于上限时，由于无法在制造期间施加足够的压力，用于管乐器的木质材料的品质会变化。
制造方法
用于管乐器的木质材料可通过一种方法制造，所述方法包括：用树脂组合物浸渍单板1(单板浸渍步骤)；用粘接剂浸渍纤维片(纤维片浸渍步骤)；将每一个单板1和用粘接剂浸渍的纤维片交替地层积(层积步骤)；和将已经对单板进行浸渍的树脂组合物和已经对纤维片进行浸渍的粘接剂硬化。
单板浸渍步骤
在单板浸渍步骤中，单板1被浸没在要对单板1进行浸渍的树脂组合物中，以由此用树脂组合物对单板1进行浸渍。要对单板1进行浸渍的树脂组合物可以用溶剂稀释。
纤维片浸渍步骤
在纤维片浸渍步骤中，用粘接剂对纤维片浸渍。优选的是，在纤维片浸渍步骤用过量的粘接剂浸渍纤维片。
层积步骤
在层积步骤中，在插入纤维片(在纤维片浸渍步骤中已经用粘接剂对其浸渍)的情况下，将已经在单板浸渍步骤中用树脂组合物浸渍的多个单板进行层积。
硬化步骤
在硬化步骤中，粘接剂在至少一个纤维片和单板1的层积结构被加压的状态下硬化。
取决于例如粘接剂的粘性、纤维片的弹性模量等来选择要应用于纤维片和单板1的层积结构的压力。通常，要应用于纤维片和单板1的层积结构的压力下限优选为0.1MPa，且更优选为0.2MPa。同时，要应用于纤维片和单板1的层积结构的压力上限优选为2MPa，且更优选为1MPa。在要应用于纤维片和单板1的层积结构的压力小于下限时，过剩的粘接剂不会被挤出且会在单板1和纤维片之间形成仅由粘接剂构成的层。另一方面，在要应用于纤维片和单板1的层积结构的压力大于上限时，纤维片会被压扁，造成缓冲层2的厚度不足。
硬化步骤中的加热温度的下限取决于粘接剂的类型，但是优选为60℃且更优选为80℃。同时，硬化步骤中的加热温度的上限优选为180℃且更优选为150℃。在硬化步骤中的加热温度小于下限时，粘接剂的效果不会被加强。另一方面，在硬化步骤中的加热温度大于上限时，单板1会被损坏。
硬化步骤中加压和加热的时间段的下限取决于粘接剂的类型，但是优选为15min且更优选为40min。同时，硬化步骤中加压和加热的时间段的上限优选为360min且更优选为300min。在硬化步骤中加压和加热的时间段小于下限时，粘接剂不会被充分硬化。另一方面，在硬化步骤中加压和加热的时间段大于上限时，制造成本会被不适当地增加。
优点
在用于管乐器的木质材料中，在插入具有特定厚度的缓冲层2的情况下对多个单板1进行层积，这会将单板1由于湿气改变而膨胀和收缩时产生的应力分配，由此能防止层间分离。因此，用于管乐器的木质材料在对湿气改变的抵抗方面是优越的。
管乐器
图2示出了根据本发明的管乐器实施例的单簧管。单簧管包括：吹嘴部件11；调节管(barrel joint)12；上节管(upper joint)13；下节管(lower joint)14；喇叭15；多个乐音孔，设置在上节管13和下节管14上；和多个按键16，用于覆盖乐音孔。
单簧管的吹嘴部件11、调节管12、上节管13、下节管14、和喇叭15用木质材料形成。图1所示的用于管乐器的木质材料用作用于形成单簧管的木质材料。
如通过图3所示的喇叭15示意性显示的，在单簧管中，木质材料包括多个单板1和插置在多个单板1中的相邻两个之间的缓冲层12。如上所述，缓冲层2包括用无纺织物或纺织织物构成的纤维片，和对纤维片进行浸渍的粘接剂。
优点
通过将单板1和缓冲层2层积而获得的木质材料所形成的单簧管：相对不贵，但是能产生的声音类似于相对昂贵的天然木材形成的单簧管的声音；产品间有很小的品质差异；和对湿气改变有优越的抵抗性。
其他实施例
如上所述的实施例并不限制本发明的构成特征。因此，可基于本说明书的描述和通常技术知识做出对实施例构成特征每一个的任何省略、替换和添加，且这种省略、替换和/或添加的特征完全落入本发明的范围。
在用于管乐器的木质材料中，单个缓冲层可以包含多个纤维片。
未被树脂组合物浸渍的单板也可以用在用于管乐器的木质材料中。因此，单板浸渍步骤可以在用于管乐器的木质材料的制造方法中省略。
除了单簧管以外，根据本发明实施例的管乐器可以是通过由木材形成的共鸣器而产生声音的任何管乐器，例如双簧管、低音管和八孔竖笛。
例子
在后文中，通过例子详细描述本发明，但是不应基于例子的描述限制本发明。
制造例子1
作为制造例子1，通过在插入用粘接剂浸渍的纤维片的情况下将浸渍了树脂组合物的多个单板进行层积，并对由此获得的层积结构进行加压和加热，从而制造用于管乐器的木质材料。
单板
作为单板，使用330mm宽、500mm长和1mm厚的矩形板形状的旋切桦木单板(rotarybirch veneers)。
树脂组合物
使用可从Mitsubishi Chemical Corporation获得的环氧树脂“JER828”作为用于浸渍单板的树脂组合物。单板被环氧树脂和硬化剂的混合物浸渍。
纤维片和粘接剂
使用0.1mm厚且按重量120g/m2的树脂浸渍片作为预先已经通过粘接剂浸渍的纤维片。
制造例子1通过以下方法获得：在插入了已经用粘接剂浸渍的纤维片的情况下，将已经用树脂组合物浸渍的十个单板层积；对层积结构进行加热，由此获得150℃的温度，同时通过使用压机在0.5MPa的压力下进行加压；并保持3小时，以使得粘接剂硬化。
制造例子2
作为制造例子2，通过将用树脂组合物浸渍的多个单板层积并对由此获得的层积结构进行加压和加热，从而制造用于管乐器的木质材料。
使用与制造例子1的单板和树脂组合物相同的单板和树脂组合物。
制造例子2通过以下方法获得：在没有片被插置的情况下，将已经用树脂组合物浸渍的十个单板层积；对层积结构进行加热，由此获得150℃的温度，同时通过使用压机在0.5MPa的压力下进行加压；和保持3小时，以使得粘接剂硬化。
从制造例子1和制造例子2每一个切出五个测试件，并针对每一个测试件测量成形之后的挤压和剪切强度。对于制造例子1和制造例子2每一个，由此测量的挤压剪切强度的平均值、最大值、和最小值显示于如下的表格1。应注意，挤压剪切强度是根据JIS-K6852(1994)测量的。
表格1
挤压剪切强度(MPa) 平均值 最大值 最小值
制造例子1 16.5 18.8 14.2
制造例子2 6.7 8.6 3.5
此外，测试件在温度调节浴中在50℃的温度和95％的相对湿度下保持72小时；和随后在温度调节浴中在50℃的温度和35％的相对湿度下保持96小时。对测试件横截面的显微镜观察发现仅制造例子2出现了层间分离。
因而，经证实的是，与仅通过粘接剂来对单板进行层积相比，通过在插入了用粘接剂浸渍的纤维片的情况下对多个单板进行层积，能更有效的防止在湿气吸收时发生层间分离。
工业应用性
根据本发明实施例的用于管乐器的木质材料和管乐器适于提供高品质且不贵的管乐器，其具有木材制造的共鸣器。
