Abstract

[课题]将透气材料、填充了吸音材的蜂窝板和反射材料层叠，相互之间胶合成吸隔音蜂窝板时，因蜂窝材单格壁面厚度薄，与透气材料的粘接是线与面的粘接，存在着难度大，粘接强度不够的问题。[解决方式]采用吸水性蜂窝材，将其单格壁端部浸入水溶性胶粘剂中，浸泡一定时间，使其软化后，施强压至粘结对象的透气材料上，以至于顶端部分变形至倒T字形，粘接面积边扩大边粘接。

Description

吸隔音蜂窝板
技术领域
本发明吸隔音板适用于工业机械、家居生活设备以及移动工具等噪声源的防音降噪。
背景技术
随着人口集中城市环境发生变化、交通网络日益发达以及住宅电气化普及的影响，增加了人们对噪音的烦恼。据日本总务省2016年度关于公害投诉调查报告，噪音投诉已居首榜，超过公害投诉。特别是针对低频率噪音的投诉，呈现年年递增趋势。为此，迫切需要对薄型轻量且方便使用的防音板的发明。
常规的叠层结构吸音板(专利文献1)，以填充了吸音泡沫的蜂窝材为芯材，再与数种适合用于吸音或隔音的材料胶合制成。这仅满足了对吸音或隔音性能的要求。但是，为使蜂窝材料和具备透气性能的表面材料(以下简称透气材料)胶合，因采取的是蜂窝材单格壁的断面与层压板平面对接的结构，这就出现单格壁的厚度薄，难以确保粘接面积的问题。
处理胶合蜂窝材和透气材料时，课题是如何最少量地使用胶粘剂而得到最大强度的方法。按照上述常规技术，为了保证强度，在对接胶合蜂窝材和透气性面板(吸音面)时，仅采用的是加大蜂窝材的单格壁端部以及单格壁表面的胶粘剂用量。
但是，粘附在蜂窝材的单格壁表面的胶粘剂，会因与作为吸音面的透气材料胶合时流向蜂窝材单格壁表面，扩展至透气材料表面，结果，透气材料的气孔和纤维间空隙被堵塞，不仅发生吸音面积的减少，还会因流入的胶粘剂产生污迹，从而降低了商品价值等派生问题。
还有，越多用胶粘剂，原料成本就越高。再之，普通胶粘剂多属第4类危险物品，倘若用量过大，也会出现妨碍产品的阻燃性能问题。
此外，作为申请的技术专利(专利文献2)，吸音面和隔音面的制得是分别利用了海绵材料的柔韧性。通过将海绵材料嵌入蜂窝材，扩大与蜂窝材的粘结面积，增强粘着在蜂窝材上的胶粘剂的粘接强度。
原由作为吸音面以及隔音面的材料局限于海绵材料，所以出现吸音或隔音性能不够充分的问题。
另外，作为申请的技术专利(专利文献3)，利用纤维毡材料的吸水性能而制得的吸音面，使得水溶性胶粘剂中的水分渗入纤维，扩大胶粘剂的渗透面积，与蜂窝材的单格壁面形成一体化复合结构，增强粘合力。
该技术存在因用于吸音面的材料局限于纤维毡，所以也出现吸音或隔音性能不够充分的问题。
另外，作为申请的技术专利(专利文献4)，给蜂窝芯材贴面加工制作各种板材时，因蜂窝芯材与表面材料粘贴的接触面只有构成蜂窝芯材的材料厚度，为保粘贴后强度，而用较多胶。为了改善，即接触面越大越佳，可用压辊施压蜂窝芯材的上下接触面，增加每个成分材料的接触面积。
该技术方法，在利用压辊施压成分材料接触面时，有着设备以及加工上问题。再就是即使技术工人也未必能对成分材料的接触面，进行全面均匀地施压加工问题。
另外，作为申请的技术专利(专利文献5)，当将由空腔多边形柱无间隔并列组成的蜂窝芯材置于一对表面材料之间，进行夹心式地胶合加工时，由于表面材料和蜂窝芯材的接触面不大，以致蜂窝芯材与表面材料粘结面积甚小(线与面粘结)，为避免粘接强度过小，采取将纤维强化树脂(表面板)的里面的接触面与蜂窝芯材的多边形柱的纵向端部进行粘结的结构。
这是在制作蜂窝材时，作为实施例之一，可通过对材料的施压、折叠等加工形成接触面。这种工艺，可得到面对表面材料的里面，上下连续交替的接触面。作为另一种实施例，还可通过切割加工、折叠加工，制得六边形的各边上下端部的断面呈T字型或L字型形状。这种工艺，可在面对表面材料的里面，蜂窝纵向端部六边形的开口部边缘，得到跨越边缘的粘结面(边缘形状)。这样，面对表面材料的里面，可得到大面积的粘结面。因此，可获得充分的粘接强度。
但是，这种工艺将失去，将多块平板叠层，边调位置边线状上胶，并将粘合的材料切割成所需宽度，这一常规方法制得的蜂窝芯材所具有的重量轻且易加工的优点。也就是说，相同面积夹心板制造时，出现因蜂窝芯材的材料增加，工艺变得复杂，制造成本加大的问题。

发明内容
本发明解决的课题
由于作为吸隔音材料使用的玻璃纤维、岩棉、陶瓷纤维、以及作为透气材料使用的诸如细金属线制得的无机纤维片材本身柔性强，有着即使顾及到其厚度和密度，但也缺少平整度和独立性的课题。
当蜂窝材与无机纤维片状的透气材料组合层压加工，便可制得确保强度，具备独立性的合适板材。尽管如此，与透气片材叠层时，因与蜂窝材单格壁端部对接，蜂窝材单格壁的厚度仅是其组成材料的厚度，粘结面积甚小，有着难以确保粘接强度的基本问题。
本发明，解决上述将金属、有机无机、多孔纤维或者空隙较大的片状透气材料与蜂窝材胶合制作吸隔音板出现的课题。
课题即是，使用蜂窝材，将泡沫注入蜂窝单格空腔，作为吸音层再和构成吸引面(声音的入射面)的透气材料胶合制造板材时，需要提高蜂窝材单格壁端与透气材料的金属纤维片材之间的粘接强度。
再之，使用的胶粘剂因其流动性，会将透气材料的纤维间空隙堵塞，间隙堵塞则减少吸音面积，以及出现透气材料表面受到流动性胶粘剂的污损，商品价值降低等派生课题。
解决技术问题的技术手段
关于由吸水性蜂窝材和吸水性蜂窝材单格充填了泡沫的吸音层、以及透气材料，加上反射材料，三层胶合制成的吸隔音蜂窝板，先将吸水性蜂窝材单格壁端部浸入水溶性胶粘剂中一定时间，使其软化后，再强力施压与吸水性蜂窝材对接的透气材料，促使单格壁端部的断面变成倒T字形状，扩大粘结面积后再粘接。
细说上述工艺，吸水性蜂窝材经水溶性胶粘剂浸泡一定时间后，吸收水分组织软化，使得胶粘剂更容易渗进蜂窝材内部。因此，蜂窝材经浸泡一定时间后，被浸泡过的单格壁端部软化的同时渗进胶粘剂。照此，一定时间浸泡后将蜂窝材单格壁端部，强力压至透气材料，端部变形至倒T字形，该状态一旦得到维持，胶粘剂则干燥硬化并粘结。胶粘剂硬化后，与蜂窝材间组成复合结构，强度大增。另外，即使蜂窝材再次被浸入水中，硬化了的粘结部分也不会发生软化。
如概念图1(a)所示，在吸水性蜂窝材的单格壁111端部附着15剂量的胶粘剂，并且附着的胶粘剂高度h1、宽度为w1。该用量的特征是，与图1(b)所示常规方法的附着高度h2以及宽度w2的胶粘剂用量相比，极少量的胶粘剂便可得到所期待的粘接强度。
如图2(a)所示，本发明是将透气材料131的面与吸水性蜂窝材单格壁111端部对接，被软化处理过的端部变至倒T字型并粘结。与此相比，常规的技术则是给蜂窝材单格壁端部涂胶，不空时间，接着便与透气材料对接，如图2(b)所示，在蜂窝材单格壁112端部软化之前，就与透气材料对接，端部的形状没变。
由图2(a)一目了然，可以看到吸水性蜂窝材的单格壁111端部的宽度t2，变形颇大，其程度比材料的厚度t1大出3倍，粘结面积也相应增大。相比之下，如图2(b)所示常规的技术，因端部不变形，取而代之的是较多量用胶，可看得出用的胶量，圆角堆高达p3、涂胶范围之扩大，以确保粘接强度。
发明效果
蜂窝材与透气材料的粘接强度受其粘结面积左右。若不对单格壁做特殊处理，可粘结的面积就仅是单格壁材料的厚度。为使蜂窝材单格壁端部变形，扩大粘结面积，已知的常规技术采用压辊等对蜂窝材压制的方法。这种方法存在着蜂窝材料施压设备以及加工上的问题。
加之，即使是技术工人，也未必能全面均匀地对蜂窝材单格壁端部施压，有着对蜂窝高度处理不均加工困难的课题。还有，迫使蜂窝材变形，有可能对其原料纸浆(纤维)组织造成破坏，降低强度的风险。
针对这些问题，发明者通过吸水性蜂窝材与水溶性胶粘剂的组合，将吸水性蜂窝材的凸起端部浸入水溶性胶粘剂中一段时间，进行解决。采用该制作方法，不会破坏蜂窝材原材料纸浆(纤维)组织，而且单格壁端部变形至倒T字型，粘结面积变大，同时，纸浆(纤维)组织还可保持相连状态并被牢固粘结。
采用最少量胶粘剂，得到的粘接强度超越破坏蜂窝材材料本身的强度。结果是大大提升了吸隔音蜂窝板整体的强度。此外，无需使用压辊施压蜂窝材，也就不需要加压设备，具有缩减制造过程的效果。
再之，因采用最少量胶粘剂，前述的课题，即透气材料的空隙或纤维间的间隙被压陷，吸音面积减少，以及胶粘剂的流动，透气材料表面出现污迹，由于污迹商品价值降低等派生问题，便可得到解决。

具体实施方式
实施例
下面就实施本发明的方式，参照附图详细说明。图11是本实施例的吸隔音蜂窝板1的截面图。显示出蜂窝材11的单格空腔内填充了泡沫材料12的吸音层、构成吸音面的透气材料13、构成隔音面的反射材料14的3种材料的叠层，之间互相粘结的结构。
那么有关反射材料14与填充了泡沫塑料12的蜂窝材11間的粘结，因为构成蜂窝材11的原材料(单格壁面材料)的厚度不仅可以利用，而且面对填充了泡沫材料12的反射材料14的面也可以用作粘结面，所以蜂窝材11的单格壁面、反射材料14側的端部无需(图11上部)变至T字形状。
就吸隔音蜂窝板1，由外部入射的声音是从透气材料13(图11下部)面进入。图11中画出相同连续形状的蜂窝材11的单格壁。为简化，只给其中一个单格标有符号11。另外，图11只显示出左右应延伸整体的一部分。(其它类似图也相同)
图8是透气材料图。显示出整体中的部分透气材料。图8(b)是图8(a)中标有A－A’部位的截面图。透气材料13是片状铝合金纤维无纺布131，置于两块铝合金拉制金属网132中间，夹心式地制得。(株式会社UniX公司产品PoAlC1)整体厚1.6mm、拉制金属网厚0.4或0.6mm、开口率40％。
虽然，作为构成吸音层的透气材料，本实施例采用铝合金纤维无纺布，但是其它的金属、有机或无机纤维的片材也可选用。
图9是未填充泡沫材料蜂窝材与透气材料重叠状况下的平面图。取整体中一小部，并从图11蜂窝材侧的鸟瞰图。
蜂窝材则如图7所示。图7切取显示了蜂窝材11的一小部。图7(a)是蜂窝材的透视图。图7(b)是图7(a)中用点破线A所标位子的截面图。关于蜂窝材11，本实施例中使用了吸水性蜂窝材(Tigalex公司产品陶瓷蜂窝HR20)。吸水性蜂窝材料的成分是例如含水硅酸镁、纸浆、二氧化硅和胶粘剂。然而，作为蜂窝材料，可以选用原料中含氢氧化铝成分的来代替含水硅酸镁。
这里所用的蜂窝材，主要以纸浆为原料，为得到不燃等特性，与作为辅助原料的硅酸镁和氢氧化铝的细颗粒混合，整体用粘合剂固定制得。这样，细颗粒之间、纸浆纤维之间出现空隙，形成多孔结构，作为蜂窝材具备吸水性能。一旦吸水，机械式缠结和化学式结合便被松解，出现膨胀和软化。
然而，不含硅酸镁和氢氧化铝、仅由纸浆制成纸蜂窝材料也可选用。此时因为蜂窝材具有可燃性，虽然有着用途受限的问题，但是壁面端部因吸水软化、变形，有着与透气材料粘结面积同样扩大的效果。
本实施例采用的蜂窝材11的六边形单格的尺寸为20mm、单格壁厚0.3mm。考虑到因变形缩短，采用的蜂窝材11，厚度为31mm。
填充蜂窝材的泡沫材料12是硬质酚醛泡沫。酚醛泡沫是通过酚醛树脂发泡制得。本实施例采用的开孔率高出95％，密度为19kg/m3产品。(松村Aqua Co.，Ltd.)由于是气泡连续的开孔气泡，吸水性能强。针对31mm厚的蜂窝材11，泡沫材料12厚度为29～30mm。然而，硬质聚氨酯泡沫也可以代替酚醛树脂泡沫使用。
反射材料14，是设置在吸音层后面，作为隔音层使用的非透气性铝制薄板。本实施例采用的厚度尺寸1.2mm。
对于层压结构的吸隔音蜂窝板，用于透气材料13与蜂窝材11胶合的胶粘剂是水溶性乳胶(KONISHI株式会社产品，CX50、不挥发成分43.5～46.5％)。如前述所说明，胶粘剂中含有的水分，可使吸水性蜂窝材11单格壁端部发生软化。
通常水溶性胶粘剂的PH値为3.5～7.0，显酸性，有水分的情况下会腐蚀金属。乳胶CX50的PH値为3.5～5.0，必须做防腐处理。所以选用高纯度材质的铝合金纤维无纺布。
图11所示，泡沫材料12的表面与蜂窝材11单格壁111端部胶合形成的面，再与反射材料14胶合用的胶粘剂16环氧胶。
下面说明吸隔音蜂窝板的制造程序。发明者通过增大蜂窝材与透气材料的粘结面积，得到的粘接强度可超越蜂窝材本身破坏的强度。
采取的方式是，将吸水蜂窝材单格壁端部浸入乳胶池内镀胶，并停留一定时间，等镀了胶部分软化后强力施压，软化部分断面变至倒T字形状，扩大粘结面积。
图3是蜂窝材壁面端部镀胶制作过程的示意图。只显示出应左右延伸整体中的一部分。如图3(a)所示，在水平放置的平台2上面，图上虽然看不出，装配有四周密封的深度设定用板21。因平台2与设定用板21形成胶池，所以注入乳胶15至设定用板21上面的高度。
如图3(a)所示，将吸水蜂窝材11单格壁111的端部，浸至乳胶15池底进行镀胶。因平台2水平放置，深度一样，因此单格壁111可完全浸入。浸泡一定时间。实施例中的蜂窝材11单格壁111的端部，约90秒后开始软化，约120秒后变得十分软化，强压透气材料便可变形。
如图3(b)所示，将吸水蜂窝材11从胶粘剂15池中取出时，吸水性蜂窝材所有单格壁111的端部均镀了与胶池相同深度高度的胶粘剂15，蜂窝材上完成镀胶的部分已经软化。本实施例，浸胶深度即胶粘剂附着高度是1mm。胶量是80～100g/m2。
此时，胶粘剂15中含有的部分水分经时逐渐地渗入吸水性蜂窝材11单格壁111内部。因水分渗透并集中在胶粘剂15上胶的部分，因此只有该集中部分发生软化。蜂窝材经软化的部分，也就是胶粘剂本身的渗入，之后一旦胶粘剂硬化，蜂窝材的原料组织相互胶合，形成强固的复合结构。
图4是蜂窝材与透气材料粘结过程示意图。如图4(a)所示，将吸水性蜂窝材11单格壁面111置于平放透气材料13之上，利用图中未画出的压力机，按照图示尖头方向，下压透气材料13，压力为5吨/m2。
如图4(b)受到透气材料13强压的吸水性蜂窝材11单格壁111端部，其断面变形至倒T字型。镀在单格壁111端部的部分胶粘剂由倒T字型的底部展开，并渗入透气材料13。另外，其它部分胶则如图2(a)说明，形成胶圆角。
通过变形至倒T字型，相对单格壁111本身厚度0.3mm，T字型的横划部分宽达0.9mm。即，粘结面积扩大到3倍。
保持该状态等待胶硬化。渗入单格壁111端部的部分胶粘剂15，与吸水性蜂窝材11的原料成分即含水硅酸镁以及纸浆(纤维)一起形成复合结构并硬化。同样地，渗入透气材料13的部分，则与构成透气材料要素之一的纤维材料形成复合结构并硬化。
图10是给蜂窝材填充泡沫过程的示意图。如图10(a)所示，将蜂窝材11单格壁111与透气材料13的胶合板置于压力机下压盘31上，上面再置放泡沫材料12。由上方往下施压压力机的上压盘32。
如图10(b)所示，随着上压盘32往下压，蜂窝材单格壁面111嵌入泡沫材料12，当泡沫材料12的上部表面达到蜂窝材单格壁面111的顶端时，停止上压盘32下压。此时，泡沫材料12的下部表面尚未达到透气材料13，两者之间仍留有空间。
上面分别对强压蜂窝材使单格壁端部变形、以及蜂窝材内填充泡沫材料的工序进行了说明。两道工序也可以同时进行。这时，只要将吸水性泡沫材料填够到镀了胶部分，涂敷在蜂窝材上的水溶性乳胶中的水分被蜂窝材吸收，有着促进胶粘剂硬化的效果。
如图11所示，采用环氧胶16全面涂敷反射材料14，并叠放在蜂窝材11上端与泡沫材料12的复合的上部表面，胶合后便完成吸隔音蜂窝板1制作。
下面详细说明具有上述结构吸隔音蜂窝板1的制造方法的效果。蜂窝材单格壁端部通过变形，扩大粘结面积，正如前述，其根本效果就是以少量用胶得强粘着力。
图5为蜂窝材单格壁的厚度平面图。单格壁面垂直于纸面。图5只描绘了未上胶状态下的单格壁。图5(a)显示了，采用本发明方法，施压单格壁端部并使其变形至倒T字型的形状。图中，六边形间的距离为形状变宽单格壁端部111d的厚度。即如图2(a)中所示的t2。此外的图5(b)显示出，根据常规技术方法未使端部变形的状况，图中，六边形间的距离为单格壁111变形前的厚度，即如图2(b)所示t1。
与图5(b)相比较，可以看出图5(a)中只有变形至倒T字型部分的单格壁厚度增大，即粘结面积扩大。因此，很显然粘接强度得到增强。
在此，使所用水溶性胶乳单体硬化，变成树脂时的拉伸强度为167kgf/cm2，此外，单体吸水性蜂窝材本身的破坏拉伸强度为2.6kgf/cm2。
综上所述，本发明即通过蜂窝单格壁面软化后，施压扩大粘结面积的工艺，使蜂窝材中纸浆(纤维)组织软化，而非使其断裂破坏，该纸浆(纤维)与渗入的胶粘剂一同硬化，形成树脂复合结构，强度应是蜂窝材与胶粘接硬化后各自分别强度的中间值(2.6～167kgf/cm2之间的值)。即当胶粘剂渗入一旦经软化、变了形的蜂窝材单格壁端部内发生质变并硬化，可以得到超越原蜂窝材本身的强度效果。
另外，水溶性乳胶硬化后变成玻璃状态的树脂。这一状态若保持一定时间还会发现，即使将硬化后树脂浸入水中，也不会发生软化，成为耐水性树脂。据其它经水实验确认，将硬化后树脂浸入水后，即使受到水的影响也不会被溶解。该复合树脂状态的耐抗强度可保持16年之久。
图6为透气材料与蜂窝材粘结时，由蜂窝材侧观看透气材料表面的顶视图，描绘了透气材料表面六边形网状上胶粘剂的扩展状况。图6(a)对应图2(a)、图6(b)对应图2(b)，均用虚线画出蜂窝材单格壁端部，实线画出蜂窝材单格壁端部周围胶粘剂的流动轮廓。
图6(a)为吸水性蜂窝材单格壁111端部111d经胶粘接，浸泡软化再被施压处理，变成倒T字形，由原本厚度t1扩大至厚度t2再经胶粘剂附着的状态。图6(b)为吸水性蜂窝材单格壁112端部镀胶后马上对接，可看到未经软化的单格壁112厚度不变，保持了原材料厚度t1状态。
再之，图6显示出蜂窝材单格壁上镀有的胶粘剂被转涂至透气材料表面，透气材料的开口部分被堵塞状态。图中6边形状或者实线圆角6边形状的内部是开口部分，六边形相互间被胶粘剂堵塞成非开口部分。图6(a)与图6(b)为由蜂窝材111、112方向观看的图2(a)与图2(b)的图。
如图6(a)实线所画开口41与图6(b)中同样实线所画开口42的大小相比，可以看出，图6(a)所示吸水性蜂窝材，针对原本材料厚度t2，其厚度仅扩大至w3，并不大。
相对而言，图6(b)的吸水性蜂窝材，因单格壁端部附着的胶量多，当蜂窝材与透气材料粘接时，附着在单格壁端部的胶被转涂至透气材料表面，再于透气材料表面水平方向上流动2～4mm，比蜂窝材厚度t1增加许多，达w4厚度。
因此，如图6(b)所示，开口部分被大幅堵塞，开口部分42与开口部分41相比，相当变小。另外为方便易解，附图用了夸张描法。
再之，当完成镀胶的蜂窝材填充泡沫材料后，蜂窝材单格壁端部的部分胶粘剂，即不能渗透且无处吸收的部分，会随着边受泡沫材料碾压边于蜂窝材周围构成透气性纤维材料的表面扩展。即，通过泡沫材料向透气材料表面进一步镀胶，粘结面积随之扩大。关于胶粘剂的扩展如上述说明，开口部被堵塞，使得开口率降低。
而如图2(a)所示，本发明采取的是，花费时间使吸水性蜂窝材单格壁端部软化、变形并胶合的方法，用少量胶便可制成，所以透气材料表面流动的胶粘剂量少，可得到开口率大的结果。
相比较，如图2(b)所示，常规技术则是，即使采用了吸水性蜂窝材，不花费时间使单格壁端部软化便粘接的方法，所以，为了获得理想的粘接强度，必须多用胶粘剂，因此透气材料表面上的胶流动量大，开口率相反变小。关于开口率的大小，开口率越大，泡沫材料吸收外部声音就越多，有助于提高吸音性能的效果。
图12为混响室法的吸声系数的图。纵轴为混响室法的吸声系数，横轴为1/3倍频带中心频率(单位为Hz)。根据本发明的结果，可以确认到针对重量8k g/m2、厚度33mm的吸隔音蜂窝板，利用混响室法的吸声系数的测定方法(JIS A 1409)，测得400～4kHz，满足高吸音率的利用。
如此，通过吸水性蜂窝材单格壁端部经水溶性胶粘剂附着、软化，并施强压与透气材料对接，待单格壁端部变形至倒T字形，实现扩大了粘结面积的同时，结果得到的是少量用胶，粘力增大，作为板材具备高强度的吸隔音蜂窝板的制造方法。
上述说明中提及的，将吸水性蜂窝材单格壁端部浸入水溶性胶粘剂中一定时间，待其软化后提出胶池，并施强压与粘接对象的透气材料对接，使得单格壁端部的断面变形至倒T字形，扩大粘结面积。也可以采取将单格壁端部浸入水溶性胶粘剂中，镀胶后适当地从胶池提出，一直保持该状态至端部软化之后，再做施强压与透气材料对接胶合。
