Description

无机纤维用粘结剂及无机纤维垫
技术领域
本发明涉及无机纤维用粘结剂，特别涉及对于作为建筑用的隔热材料、吸音材料等优选使用的无机纤维垫、挥发性有机化合物的放出极少、具有足够的厚度并且给予优异的复原性的无机纤维用粘结剂及用该粘结剂处理过的无机纤维垫。
背景技术
目前为止，由玻璃棉、岩棉等无机纤维构成的无机纤维垫在产业用、住宅用的隔热材料、吸音材料中广泛地使用。无机纤维垫一般采用以水溶性酚醛树脂作为主成分的粘结剂将无机纤维之间固定，成型为垫状而制造(例如日本特开昭58-070760号公报：专利文献1)。
但是，作为上述粘结剂的主成分使用的水溶性酚醛树脂一般使用甲醛作为交联剂，因此将粘结剂加热固化时，具有未反应的甲醛在无机纤维垫中残留的问题。另外，固化后也具有由于粘结剂的水解、缩合反应的进行而产生甲醛的问题。在这种情况下，上述甲醛从制造后的无机纤维垫的表面、侧面放出。
关于如甲醛那样在常温常压下在空气中容易挥发的挥发性有机化合物，近年来，随着挥发性有机化合物造成的室内空气的污染变得明显，将挥发性有机化合物视为原因之一的病态建筑综合症等健康损害成为了问题。因此，在法律上对从建筑材料的甲醛的放出量进行了管制。因此，为了甲醛及其他挥发性有机化合物使从建筑材料的放出量极少，认为使它们的含量极少是有效的。
从无机纤维垫放出的挥发性有机化合物主要是粘结剂中所含的甲醛，因此为了解决上述问题，必须使粘结剂中使用的组合物成为不含甲醛的组合物。但是，对于使用了现有的以酚醛树脂作为主成分的粘结剂的无机纤维垫而言，原料成本低，进而垫的复原率非常优异。因此，即使使用以不含甲醛的组合物作为主成分的粘结剂，也必须具有这些性能，但具备同等的性能困难。
为了应对上述问题，在日本特开2005-299013号公报(专利文献2)中提出了以丙烯酸系树脂系乳液作为主成分的粘结剂，另外，在日本特开2006-089906号公报(专利文献3)中提出了由具有羧基等官能团的乙烯基共聚物构成的粘结剂。但是，使用这些粘结剂得到的无机纤维垫的复原率比使用包含水溶性酚醛树脂的粘结剂得到的无机纤维垫差。进而，本申请人在日本特开2011-153395号公报(专利文献4)中也公开了含有具有羟基的水溶性高分子化合物和硼化合物的粘结剂。但是，使用该粘结剂得到的无机纤维垫虽然将挥发性有机化合物的问题清除，但与水溶性酚醛树脂相比，复原率略差。
在国际公开第2005/092814号(专利文献5)中提出了马来酸酐与不饱和单体的不饱和共聚物(具体地，马来酸酐与丁二烯的不饱和共聚物)，在日本特开2012-136385号公报(专利文献6)中提出了马来酸酐与丙烯酸酯的共聚化合物，在日本特开2016-108707号公报(专利文献7)及日本特开2016-108708号公报(专利文献8)中提出了马来酸共聚物(认为是甲基乙烯基醚/马来酸酐共聚物单烷基酯)，在日本特开昭60-046951号公报(专利文献9)中提出了异丁烯-马来酸酐的共聚物。由无机纤维构成的无机纤维垫通过将低浓度的水溶性粘结剂向熔融玻璃喷雾而制造，上述的化合物等均缺乏在水中的溶解度，不一定得到适宜的水溶性粘结剂。

具体实施方式
以下对本发明具体地说明。
本发明的无机纤维用粘结剂为下述的无机纤维用粘结剂，其特征在于，含有下述(A)～(C)成分：
(A)聚合度为100～3500的聚乙烯醇系树脂：100质量份，
(B)金属盐：1～50质量份，和
(C)含有马来酸酐的共聚物的氨改性物：3质量份以上。
(A)成分的聚乙烯醇系树脂为本发明的无机纤维用粘结剂的主剂。(A)聚乙烯醇系树脂的聚合度为100～3500，优选100～2000，更优选200～1800。如果超过3500，有时发生产生喷涂引起的涂布不良、得不到必要的附着量、在无机纤维垫中得不到充分的复原性等不利情形。在不到100的情况下，有时发生在无机纤维垫中得不到充分的复原性等不利情形。上述聚合度作为重均聚合度，是采用水系凝胶渗透色谱(GPC)分析得到的聚苯乙烯换算的值。另外，聚乙烯醇系树脂的皂化度基于JIS K6726的试验方法，优选70mol％以上，更优选80mol％以上，上限值优选为不到99.5mol％。如果该皂化度为99.5mol％以上，有时低温下粘度上升变大而凝胶化。
作为上述(A)成分的聚乙烯醇系树脂，能够使用市售品，例如可列举出JAPAN VAM&POVAL CO.,LTD.制的“POVAL(PVA)”。
对(B)成分的金属盐并无特别限定，优选为选自从钠、钾、镁、钙、锶、钡、钛、锆、锰、铁、钴、镍、铜、锌、铝中选择的1种以上的金属的氧化物、氢氧化物、碳酸盐、硫酸盐、硅酸盐、钛酸盐、醋酸盐、苯甲酸盐中的1种以上。更优选为选自从钠、镁、钙、钡中选择的1种以上的金属的氢氧化物、碳酸盐、硫酸盐、硅酸盐、醋酸盐中的1种以上。特别优选为具有1价或2价的金属的金属盐。
具体地，可列举出氧化钛、氧化锌、氧化镁、氢氧化钙、氢氧化铝、氢氧化镁、碳酸钠、碳酸钙、碳酸镁、硫酸钙、硫酸钡、硫酸镁、硅酸钙、钛酸钾、钛酸钙、钛酸钡、醋酸钙、苯甲酸钠等。
再有，(B)成分的金属盐优选平均粒径为50μm以下，更优选为20μm以下且10nm以上。如果平均粒径超过50μm，有时沉淀。平均粒径用采用激光衍射法得到的中值径(D50)测定。
(B)成分的金属盐相对于(A)聚乙烯醇系树脂100质量份，为1～50质量份，优选为3～40质量份。如果超过50质量份，则具有凝胶化这样的不利情形。另外，如果不到1质量份，有时发生复原性降低这样的不利情形。
将(B)成分的金属盐加入在水中溶解的(A)聚乙烯醇系树脂的水溶液，采用高速分散机分散。
(C)成分的含有马来酸酐的共聚物的氨改性物在本发明中作为交联剂发挥功能。作为(C)成分的含有马来酸酐的共聚物的氨改性物，并无特别限定，可列举出下述通式的共聚物。
[化2]
Figure BDA0003513840890000061
上述式中，R1及R2各自为碳数2～5的直链状或分支状的亚烷基，另外，可具有1～2个不饱和基团，例如可列举出亚乙基、亚丙基、异亚丙基、正亚丁基、异亚丁基、亚乙基-亚丙基、丁二烯基等，R1及R2可彼此相同，也可不同。
作为上述(C)成分，例如可列举出马来酸酐与异丁烯、异丙烯、乙烯、乙烯-丙烯、丁二烯等的共聚物的氨改性物。特别优选由下述结构式表示的异丁烯-马来酸酐共聚物的氨改性物。
[化3]
Figure BDA0003513840890000062
(C)成分的含有马来酸酐的共聚物的氨改性物的重均分子量优选50,000～300,000，更优选50,000～200,000，最优选50,000～100,000。该重均分子量为采用水系凝胶渗透色谱(GPC)分析得到的聚苯乙烯换算的值。
另外，上述式中的n、m为正数，n和m表示质量比例，n相对于n+m的合计100质量％，优选50～90质量％，更优选70～80质量％。
就(C)成分的含有马来酸酐的共聚物的氨改性物的含量而言，相对于(A)成分的聚乙烯醇系树脂100质量份，为3质量份以上，优选为3～20质量份，更优选为3～10质量份。如果含有马来酸酐的共聚物的氨改性物的含量不到3质量份，有时发生交联性不足等不利情形，在比20质量份多地配混的情况下，在与(A)成分的聚乙烯醇系树脂的混合性上没有问题，但处理水溶液着色为黄色，制品品质降低，进而，有时也导致成本升高。
作为上述(C)成分的含有马来酸酐的共聚物，能够使用市售品，例如可列举出可乐丽株式会社制造的“ISOBAM”等。
进而，在本发明的无机纤维用粘结剂中，除了(A)聚乙烯醇系树脂、(B)金属盐、(C)含有马来酸酐的共聚物的氨改性物以外，可根据需要加入尿素等保水材料、硅烷偶联剂、防水剂、pH调节剂、着色剂等添加剂。这些添加剂的添加量在不损害本发明的效果的范围内能够设为任意。
本发明的无机纤维用粘结剂优选溶解于水而作为无机纤维用粘结剂水溶液使用。上述无机纤维用粘结剂水溶液的粘度在25℃下优选为1～100mPa·s，特别优选为1～50mPa·s。应予说明，该粘度值为采用旋转粘度计的测定值。如果粘度超过100mPa·s，成为喷雾(排出)不良，加工后的粘结剂附着量减少，因此有时不能发挥本发明的效果。另外，其浓度优选10质量％以下，更优选5质量％以下，最优选3质量％以下。
另外，上述无机纤维用粘结剂水溶液的pH优选为4～10。如果pH在上述范围以外，则交联性变化，有时对复原性产生影响。
本发明的无机纤维用粘结剂可在各种无机纤维中使用，特别是对于玻璃棉、岩棉，发挥优异的效果。
本发明的无机纤维垫通过用上述无机纤维用粘结剂对无机纤维进行处理而形成。作为用于上述无机纤维垫的无机纤维，并无特别限定，优选为优选平均粒径1～10μm的玻璃棉、岩棉。
作为无机纤维的纤维化方法，能够采用离心法、吹散法等现有公知的方法。进而，无机纤维垫的密度也可为通常的隔热材料、吸音材料中所使用的密度，优选为40kg/m3以下，更优选为32kg/m3以下。
就无机纤维用粘结剂的使用量而言，相对于无机纤维，以固体成分比率计，优选1～10质量％，更优选1～5质量％。如果不到1质量％，有时发生将缺乏复原性的无机纤维垫成型等不利情形，如果超过10质量％，有时发生将硬且溃散的无机纤维垫成型等不利情形。
参照图1及图2对使用本发明的无机纤维用粘结剂制造无机纤维垫的方法的一例进行说明。图1为表示使用本发明的无机纤维用粘结剂制造无机纤维垫的工序的一个实施方式的示意图，图2为表示将本发明的无机纤维用粘结剂赋予无机纤维的工序的一个实施方式的斜视图。
首先，采用纤维化装置1进行将玻璃棉等无机纤维纺出的纤维化工序。其中，作为采用纤维化装置1的纤维化的方法，并无特别限定，可列举出现有公知的离心法、吹散法等。另外，纤维化装置1也可根据制造的无机纤维垫7的密度、厚度和宽度方向的长度设置多个。
其次，如图2中所示那样，采用粘结剂赋予装置2，对从纤维化装置1纺出的无机纤维3赋予本发明的粘结剂。作为粘结剂的赋予方法，能够采用现有公知的方法，例如，使用上述粘结剂水溶液，能够采用喷涂法等赋予。从纤维的上层部，直接或从倾斜方向，以纤维之间的交点部分为主，对交点以外的部分也使粘结剂附着来进行处理。
输送机41为将未固化的粘结剂附着的无机纤维3在有孔的输送机上层叠的装置，为了使纤维均匀地层叠，输送机41优选为具有抽吸装置的有孔的输送机。
其中，所谓本发明中的粘结剂的附着量，为采用强热减量法或称为LOI(Loss ofIgni t ion)的方法测定的量，意指通过在约550℃下对粘结剂附着后的无机纤维垫的干燥试样给予强热、减量而失去的物质的质量。
通过上述工序，使赋予了粘结剂的无机纤维3堆积于在纤维化装置1的下方配置的输送机41，连续地移动至沿着生产线方向设置的输送机42。然后，采用输送机42及在输送机42上以规定间隔相对配置的输送机5，将堆积的无机纤维3压缩为规定的厚度，同时进入在输送机42及输送机5的位置配设的成型炉6。
在成型炉6中，对无机纤维3赋予的本发明的粘结剂加热固化，形成规定的厚度的无机纤维垫7。再有，加工条件由于生产线的长度等而大幅地变化，因此可适当地设定。例如，本实施例的情况下，加热温度优选为150～300℃，更优选为180～250℃。如果加热温度比150℃低，有时无机纤维垫7的水分没有完全地蒸发，如果比300℃高，有时对无机纤维垫7处理的粘结剂碳化。另外，加热时间优选为120～360秒，更优选为180～300秒。如果加热温度比120秒短，有时无机纤维垫7的水分没有完全地蒸发，如果比360秒长，有时对无机纤维垫7处理的粘结剂碳化。而且，将形成的无机纤维垫7采用设置在输送机43的部分的切断机8切断成规定的制品尺寸后，采用输送机44运输，包装、捆包。
这样制造的本发明的无机纤维垫与用现有技术提出的以酚醛树脂为首的粘结剂处理过的无机纤维垫相比，具有优异的复原率等，同时挥发性有机化合物从无机纤维垫的放出量极少。
再有，根据JIS，将甲醛散放速度区分为数个等级。例如，在JIS-A9504中区分为F☆☆～F☆☆☆☆这3等级，分别是甲醛散放速度为5μg/m 2·h以下时为F☆☆☆☆型，超过5μg/m2·h且20μg/m2·h以下时为F☆☆☆型，超过20μg/m2·h且120μg/m2·h以下时为F☆☆型。F☆☆☆☆型最优异，在使用了本发明的无机纤维用粘结剂的情况下，在基于JIS-A1901的腔室法的试验中，能够制造F☆☆☆☆型的无机纤维垫。
另外，所谓本发明中的无机纤维垫的复原率，用施加了外力压缩后去除外力而复原后的无机纤维垫的厚度与压缩前的无机纤维垫的厚度之比表示。就无机纤维垫而言，为了提高保管、输送的效率，有时将一定数量以上的无机纤维垫一并压缩而捆包。因此，在开捆得到的无机纤维垫不能确保压缩前的厚度的情况下，即，在无机纤维垫的复原率差的情况下，有时无法充分地获得隔热性、吸音性等性能。
