Description
本発明は、貯湯タンク等、高温タンク用断熱・吸音材として好適なグラスウール断熱材の製造方法及びこの方法で製造されたグラスウール断熱材に関する。 The present invention relates to a method for producing a glass wool heat insulating material suitable as a heat insulating and sound absorbing material for a high-temperature tank such as a hot water storage tank, and a glass wool heat insulating material produced by this method.
貯湯タンク等、高温タンク用断熱・吸音材として、ガラス短繊維（グラスウール）を使用したものが市販されている。このようなグラスウールは、バインダーによって繊維同士を固定し、自身の形状を保持している。しかし、有機バインダーを使用したグラスウールは、高温部に施工するとバインダーの熱分解等によりガスが発生し、劣化、悪臭等の原因となっていた。また、無機バインダーを使用した場合は、グラスウールの脆性のため、貯湯タンク等の振動に対応できず劣化し易かった。 As heat insulation and sound absorbing materials for high-temperature tanks such as hot water storage tanks, those using short glass fibers (glass wool) are commercially available. Such glass wool fixes the fibers with a binder and maintains its own shape. However, when glass wool using an organic binder is applied to a high temperature part, gas is generated due to thermal decomposition of the binder, which causes deterioration, bad odor and the like. In addition, when an inorganic binder was used, glass wool was brittle, so that it could not cope with vibrations in a hot water storage tank or the like and was easily deteriorated.
一方、バインダーを使わずに成形した、ノーバインダー・グラスウールも製造されたが、形状を長期間維持することが困難であり、施工後に膨らんできて断熱・吸音機能が低下し、外見も悪くなるという問題があった。さらに、ノーバインダー・グラスウールをニードル加工して、ガラス繊維同士の絡み度を増すことで形状維持をはかった断熱材も市販されている。しかし、ガラス繊維同士の絡みだけで形状を長期間にわたって維持することは困難であり、形状維持のためニードル加工回数を増すと、今度はニードルによりガラス繊維の破断が生じてしまうという難点があった。 On the other hand, no-binder glass wool molded without using a binder was also produced, but it was difficult to maintain the shape for a long time, and it expanded after construction, and the heat insulation / sound absorption function decreased, and the appearance also deteriorated There was a problem. Furthermore, a heat-insulating material that maintains the shape by increasing the degree of entanglement between glass fibers by needle-processing no-binder glass wool is also commercially available. However, it is difficult to maintain the shape for a long time only by the entanglement between the glass fibers, and if the number of times of needle processing is increased to maintain the shape, there is a difficulty that the glass fiber breaks due to the needle this time. .
特許文献１には、ガラス繊維からなる中間層部と、中間層部の表裏両面に積層されたポリエステル系長繊維不織布層とからなり、かつニードルパンチ処理により表裏両面の不織布を構成するポリエステル系長繊維同士が交絡するとともに、該繊維が中間層部を構成するガラス繊維と絡み合うことによって一体化したアスファルトルーフィング用積層シートが開示されている。 Patent Document 1 discloses a polyester-based length comprising an intermediate layer portion made of glass fiber and a polyester-based long fiber nonwoven fabric layer laminated on both front and back surfaces of the intermediate layer portion, and constituting a nonwoven fabric on both front and back surfaces by needle punching. A laminated sheet for asphalt roofing is disclosed in which fibers are entangled and integrated with each other by entanglement of the fibers with glass fibers constituting the intermediate layer portion.
特許文献１に開示される技術では、表裏両面の不織布を構成するポリエステル系長繊維同士を交絡さなければならないため、断熱材の厚さが制限されるという問題がある。
また、熱圧接により各繊維間を熱圧着固定することも提案されているが、熱圧接では繊維同士の結合度合いをコントロールすることが困難である。
さらに、樹脂含浸によって繊維同士を固定することも提案されている。しかし、樹脂含浸を行うと既述の通り有機物の分解ガスが発生するため、高温部用断熱・吸音材として使用するには不適である。
The technique disclosed in Patent Document 1 has a problem that the thickness of the heat insulating material is limited because polyester-based long fibers constituting the nonwoven fabric on both the front and back surfaces must be entangled.
In addition, it has also been proposed to fix the fibers by thermocompression bonding by hot pressing, but it is difficult to control the degree of bonding between the fibers by hot pressing.
Furthermore, it has also been proposed to fix fibers by resin impregnation. However, when resin impregnation is performed, decomposition gas of organic matter is generated as described above, so that it is unsuitable for use as a heat insulation / sound absorbing material for high temperature parts.
本発明のグラスウール断熱材の製造方法は、バインダーを使用せずに成形したシート状または板状のグラスウールを芯材とし、芯材の両面に、それぞれ不織布を重ね合わせて積層体とし、この積層体をニードル加工することにより、グラスウール芯材を構成するガラス繊維の一部を、両面に積層された不織布を構成する繊維と絡み合わせる。 The method for producing a glass wool heat insulating material according to the present invention comprises a sheet or plate-shaped glass wool molded without using a binder as a core material, and a laminate by laminating nonwoven fabrics on both sides of the core material. By knitting, a part of the glass fiber constituting the glass wool core material is entangled with the fiber constituting the nonwoven fabric laminated on both sides.
前記ニードル加工を複数回繰り返し、グラスウール芯材を高密度化することにより、曲面部等の複雑形状に施工可能な断熱材を製造することができる。本発明のグラスウール断熱材は上記方法で製造したものであり、グラスウール芯材を構成するガラス繊維の一部が、両面に積層された不織布を構成する繊維と絡み合って形成されている。 By repeating the needle processing a plurality of times and densifying the glass wool core material, a heat insulating material that can be constructed in a complicated shape such as a curved surface portion can be manufactured. The glass wool heat insulating material of the present invention is manufactured by the above-described method, and a part of the glass fibers constituting the glass wool core material is entangled with the fibers constituting the nonwoven fabric laminated on both surfaces.
本発明の断熱材の製造方法により製造した断熱材は、ニードル加工により、グラスウール芯材を構成するガラス繊維の一部と、グラスウール芯材の両面を覆う不織布の繊維とが絡み合うため、製造時の厚さを長期にわたって保持することができる。また、バインダーを使用しないため高温部分に使用しても有機物分解ガスが発生せず、悪臭もない。さらに、両面に不織布が配置されているためガラス繊維が多少切れても、その飛散を防止することができる。 Since the heat insulating material manufactured by the method for manufacturing a heat insulating material of the present invention is intertwined with a portion of the glass fiber constituting the glass wool core material and the nonwoven fiber covering both surfaces of the glass wool core material by needle processing, The thickness can be maintained over a long period of time. In addition, since no binder is used, organic substance decomposition gas is not generated even if it is used in a high temperature part, and there is no odor. Furthermore, since the nonwoven fabric is arrange | positioned on both surfaces, even if glass fiber cuts a little, the scattering can be prevented.
また、ニードル加工を複数回行うことで、曲面部等の複雑形状箇所に適用可能な高密度断熱材を製造することができる。 Further, by performing the needle processing a plurality of times, it is possible to manufacture a high-density heat insulating material that can be applied to a complicated shape portion such as a curved surface portion.
以下に本発明の詳細を図によって説明する。図1は、本発明のグラスウール断熱材の一例を示す概要図である。断熱材１は、シート状または板状のグラスウール芯材２の両面に、それぞれ不織布３、３を重ね合わせて積層体とし、この積層体を複数本のニードル４によって、不織布３の一方から、不織布３、グラスウール芯材２、および裏面の不織布３をまとめて貫通させることにより製造する。 Details of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing an example of the glass wool heat insulating material of the present invention. The heat insulating material 1 is formed by laminating non-woven fabrics 3 and 3 on both surfaces of a sheet-like or plate-like glass wool core material 2 to form a laminated body, and the laminated body is formed from a non-woven fabric 3 by one or more needles 4. 3, the glass wool core material 2 and the nonwoven fabric 3 on the back surface are collectively penetrated.
本発明で使用するグラスウール芯材２はホワイトウールとも呼ばれ、ガラス短繊維を綿状に成形したバインダーを含まない材料である。この条件を満たすグラスウール芯材２であれば、どのようなものでも使用可能であるが、例えば、平均径が１〜１０μｍ、坪量５００〜１，５００ｇ／ｍ３のものが好適に使用できる。 The glass wool core material 2 used in the present invention is also called white wool, and is a material that does not contain a binder in which short glass fibers are formed into a cotton shape. Any glass wool core material 2 satisfying this condition can be used, but for example, those having an average diameter of 1 to 10 μm and a basis weight of 500 to 1,500 g / m 3 can be suitably used.
また、不織布３についても特に制限はなく、天然、合成の有機繊維、無機繊維から適宜選択することができる。有機繊維は無機繊維と比較して耐熱性には劣るがグラスウールと絡み易いという利点もある。ニードル４についても特に制限はないが、不織布３の繊維と芯材２のガラス繊維とを適度に押し出し絡ませることができ、かつ、ガラス繊維を破断させない程度の先端形状と太さを有するものである必要がある。 Moreover, there is no restriction | limiting in particular also about the nonwoven fabric 3, It can select suitably from a natural, synthetic organic fiber, and an inorganic fiber. Organic fibers are inferior in heat resistance compared to inorganic fibers, but have the advantage of being easily entangled with glass wool. Although there is no restriction | limiting in particular also about the needle 4, It has a front-end | tip shape and thickness which can extrude the fiber of the nonwoven fabric 3 and the glass fiber of the core material 2 moderately, and do not break a glass fiber. There must be.
図２は、本発明の断熱材を構成するグラスウール芯材のガラス繊維と不織布の繊維との絡み状態を示す概念図である。ニードル加工により、グラスウール芯材２を構成するガラス繊維２ａに不織布３の一部が押し込まれ、不織布３の繊維と絡み合っている。尚、不織布３の目付を増すと全体の厚みは薄くなることが判明した。例えば、目付２０ｇ／ｍ２のときの全体厚みは１０ｍｍであったが、目付４０ｇ／ｍ２のときの全体厚みは８ｍｍとなった。これは不織布とグラスウールとの絡みつきが多くなるからと考えられる。 FIG. 2 is a conceptual diagram showing the entanglement state between the glass fiber of the glass wool core material and the non-woven fiber constituting the heat insulating material of the present invention. A part of the nonwoven fabric 3 is pushed into the glass fibers 2 a constituting the glass wool core material 2 by the needle processing, and is intertwined with the fibers of the nonwoven fabric 3. In addition, when the fabric weight of the nonwoven fabric 3 was increased, it became clear that the whole thickness became thin. For example, the overall thickness at a basis weight of 20 g / m 2 was 10 mm, but the overall thickness at a basis weight of 40 g / m 2 was 8 mm. This is considered because the entanglement between the nonwoven fabric and the glass wool increases.
図２ではグラスウール芯材２の片面の不織布３のみを示したが、図示しない他方の不織布３においても同様の絡みが生じ、その結果、グラスウール芯材２と不織布３、３が一体化される。なお、ニードル加工の回数は、１回で十分であるが、２回、またはそれ以上の回数のニードル加工を行えば断熱材の密度を高くすることができる。このような高密度化断熱材は、曲面部の断熱用として好適である。 Although only the nonwoven fabric 3 on one side of the glass wool core material 2 is shown in FIG. 2, the same entanglement occurs in the other nonwoven fabric 3 (not shown). As a result, the glass wool core material 2 and the nonwoven fabrics 3 and 3 are integrated. In addition, although the number of times of needle processing is enough, if the needle processing is performed twice or more times, the density of the heat insulating material can be increased. Such a densified heat insulating material is suitable for heat insulation of the curved surface portion.
本発明の断熱材を実施例によって、さらに詳細に説明する。
（実施例１）
坪量５００ｇ／ｍ３のシート状ホワイトウールを使用し、このホワイトウールの両面に不織布を重ねてニードル加工を１回行った。その結果、芯材厚さ（「初期厚さ」と呼ぶ）８ｍｍの断熱・吸音材が出来上がった。この断熱・吸音材の厚さを３０日後（経時厚さと呼ぶ）に測定したところ変化はなく、初期厚さが保持されていた。
The heat insulating material of the present invention will be described in more detail with reference to examples.
Example 1
A sheet-like white wool having a basis weight of 500 g / m 3 was used, and the nonwoven fabric was overlapped on both sides of the white wool, and needle processing was performed once. As a result, a heat insulating and sound absorbing material having a core material thickness (referred to as “initial thickness”) of 8 mm was completed. When the thickness of the heat insulating and sound absorbing material was measured after 30 days (referred to as the time-lapse thickness), there was no change and the initial thickness was maintained.

Except having used the sheet-like white wool from which basic weight differs, operation similar to Example 1 was performed and the heat insulating material of Example 2 and 3 was shape | molded. Moreover, the operation similar to an Example was performed except not using a nonwoven fabric, and the heat insulating material of Comparative Examples 1-3 was shape | molded. These results are shown in Table 1.
表１に示す通り、不織布を使用した実施例の断熱・吸音材は初期厚さが保持されていたが、不織布を使用しない比較例のホワイトウールは経過厚さが初期厚さの１．５倍になっていた。 As shown in Table 1, the initial thickness of the heat insulating and sound absorbing material of the example using the nonwoven fabric was maintained, but the white wool of the comparative example not using the nonwoven fabric had an elapsed thickness of 1.5 times the initial thickness. It was.
（実施例４〜６）、（比較例４〜６）
ニードル加工を２回とした以外は、実施例１〜３および比較例１〜３と同様に操作を行ったところ、比較例４〜６のグラスウールは破断した。実施例４〜６の断熱・吸音材については表1に示す評価を行った。表１に示す通り、実施例４〜６の断熱・吸音材はニードル１回のものに比較して密度が高くなっていて経年厚さも変化がないため、曲部分等の複雑形状体への施工に適する。

The glass wool of Comparative Examples 4 to 6 was broken when the same operation as in Examples 1 to 3 and Comparative Examples 1 to 3 was performed except that the needle processing was performed twice. The heat insulation and sound absorbing materials of Examples 4 to 6 were evaluated as shown in Table 1. As shown in Table 1, the heat insulating and sound absorbing materials of Examples 4 to 6 are higher in density than those of a single needle and have no change in thickness over time. Suitable for.
