Abstract
Description
本発明は、高い断熱性と吸音性を有する屈曲可能で比較的安価な断熱吸音材に関し、特に厳しい航空機の新規要求仕様に適合する断熱吸音材に関する。 The present invention relates to a bendable and relatively inexpensive heat insulating sound absorbing material having high heat insulating properties and sound absorbing properties, and more particularly to a heat insulating sound absorbing material that meets new requirements for strict aircraft.
日本では、鉄道車両用の吸音材として、特公昭６３−１９６２２号公報に開示するように、ガラスウールやロックウールに少量の有機性樹脂を含浸し、板状に成形した断熱性の吸音材を使用していた。この吸音材は、含浸させる樹脂が可燃性であると燃焼時に有毒ガスを発生し、軽量でないので車両重量が増加しやすい。この点を改良した実公平６−４７７１５号公報では、アクリル焼成の耐炎繊維ラップをニードルパンチングし、さらにアクリル焼成耐炎繊維のニードルフェルトまたは織布からなる表面シートを貼り合わせている。この吸音材は、比較的軽量であるので車両の重量増加が少なく、高耐熱性が必要でない新幹線車両を含む日本の鉄道車両において採用されている。 In Japan, as disclosed in Japanese Examined Patent Publication No. 63-19622, as a sound absorbing material for railway vehicles, a heat insulating sound absorbing material formed by impregnating glass wool or rock wool with a small amount of an organic resin and molding it into a plate shape is used. I was using it. If the resin to be impregnated is flammable, this sound absorbing material generates a toxic gas at the time of combustion, and the weight of the vehicle tends to increase because it is not lightweight. In Japanese Utility Model Publication No. 6-47715 in which this point is improved, an acrylic fired flame resistant fiber wrap is needle punched, and a top sheet made of needle felt or woven fabric of acrylic fired flame resistant fiber is bonded. This sound-absorbing material is used in Japanese railway vehicles including Shinkansen vehicles that do not require high heat resistance because of its relatively light weight and little increase in vehicle weight.
また、自動車用の吸音材には、従来、ガラスウールの表面にアルミシートを貼着したものを用いていた。この吸音材は、エンジンルームにおいて相当に高温になる排気マフラーの付近に設置すると、高温には耐えても吸音性が不十分であった。このため、特開昭５９−２２７４４２号では、高軟化点を有する短繊維を合成繊維の不織布に散布した後にニードリングを施し、得た耐熱性の表皮材を接着剤を介してガラスウールの表面に積層し、さらに加熱・加圧で成形している。この吸音材は、仕様繊維の融点がいずれも３００℃以下であるため、高温耐熱性が要求されるエンジンルームに用いるには表皮材の耐熱性が不足する。また、特開２００６−１３８９３５号に開示の吸音材は、熱溶融温度または熱分解温度が３７０℃以上の耐熱性有機繊維を含有する繊維シートからなる表皮材と、同様の耐熱性有機繊維を含有する厚さ２〜１００ｍｍの不織布とを積層している。この吸音材は、自動車用途においてほぼ満足すべき耐熱性を有している。
断熱性の吸音材を航空機に用いる場合には、事故が発生した際の被害人数の多さおよび危険性の高さを考慮して、一般の鉄道車両用または自動車用の吸音材に比べて、耐熱・断熱性に対する要求が非常に厳しい。航空機用の吸音材は、主たる不織布が通常のガラスウールやロックウールまたは耐熱性有機繊維からなり、該不織布の表面に積層する表皮材についても同様の素材であった。このため、この吸音材は、断熱温度と耐熱性の点で航空機に関する不織布の要求仕様に適合させることは難しい。 When using heat-absorbing sound-absorbing materials for aircraft, considering the large number of victims and the high risk when accidents occur, compared to sound absorbing materials for ordinary railway vehicles or automobiles, The requirements for heat resistance and heat insulation are very strict. In the sound absorbing material for aircraft, the main nonwoven fabric is made of ordinary glass wool, rock wool or heat-resistant organic fiber, and the skin material laminated on the surface of the nonwoven fabric is the same material. For this reason, it is difficult for this sound-absorbing material to be adapted to the required specifications of nonwoven fabrics for aircraft in terms of heat insulation temperature and heat resistance.
一方、特開２００５−３３５２７９号は、自動車、電車、航空機などの内装に用いる易成形性の吸音材であると開示し、該吸音材では不織布の片面に表皮材が積層され、この表皮材に樹脂バインダーを含有している。この吸音材は、成形性の点では有効であっても、有機繊維の不織布を用いる点では前記と同様であり、航空機に関する不織布の新規要求仕様に適合させることは不可能である。 On the other hand, Japanese Patent Application Laid-Open No. 2005-335279 discloses that it is an easily moldable sound absorbing material used for interiors of automobiles, trains, aircrafts, etc., and in the sound absorbing material, a skin material is laminated on one side of a nonwoven fabric. Contains a resin binder. Although this sound absorbing material is effective in terms of formability, it is the same as described above in that an organic fiber non-woven fabric is used, and it is impossible to meet the new requirements for non-woven fabric related to aircraft.
本発明は、従来の吸音材に関する高温断熱性の問題点を改善するために提案されたものであり、特に高い断熱性および吸音性によって安全性の高く且つ比較的安価な断熱吸音材を提供することを目的としている。本発明の他の目的は、高い断熱性および吸音性を達成するとともに、設置場所に応じて屈曲可能な断熱吸音材を提供することである。本発明の別の目的は、航空機に関する不織布の新規要求仕様に適合する航空機用の断熱吸音材を提供することである。 The present invention has been proposed in order to improve the problem of high-temperature heat insulation related to conventional sound-absorbing materials, and provides a heat-insulating sound-absorbing material that is highly safe and relatively inexpensive due to particularly high heat-insulating properties and sound-absorbing properties. The purpose is that. Another object of the present invention is to provide a heat insulating sound-absorbing material that achieves high heat insulating properties and sound absorbing properties and can be bent according to the installation location. Another object of the present invention is to provide an adiabatic sound-absorbing material for aircraft that meets the new requirements for nonwoven fabrics related to aircraft.
本発明に係る断熱吸音材は、ガスバーナーの炎を５分間当接する燃焼試験においてマット材に穴が開かず、この燃焼試験の際にマット背面に手をかざすことができる。本発明の断熱吸音材は、高温強度を１０００℃以上で維持する高耐熱性の無機繊維４０〜８０％と、混綿前にあらかじめ難燃剤で処理した有機繊維２０〜６０％とを均一に混綿する。得た綿状素材を熱処理することによって全体をマット化し、この断熱吸音材の厚さは８〜５０ｍｍである。 The heat insulating sound-absorbing material according to the present invention does not open a hole in the mat material in a combustion test in which a flame of a gas burner is in contact for 5 minutes, and can hold a hand on the back surface of the mat during the combustion test. The heat insulating sound-absorbing material of the present invention uniformly blends 40 to 80% of highly heat-resistant inorganic fibers that maintain high-temperature strength at 1000 ° C. or more and 20 to 60% of organic fibers that have been treated with a flame retardant before blending. . The obtained cotton-like material is heat treated to form a mat, and the thickness of the heat insulating sound absorbing material is 8 to 50 mm.
本発明に係る他の断熱吸音材は、高温強度を１０００℃以上で維持する高耐熱性の無機繊維４０〜８０％と、有機繊維２０〜６０％とを均一に混綿する。得た綿状素材の少なくとも片面に難燃性樹脂を付与するとともに全体がマット化され、この断熱吸音材の厚さは８〜５０ｍｍである。 The other heat insulating sound-absorbing material according to the present invention uniformly blends 40 to 80% of highly heat-resistant inorganic fibers that maintain high-temperature strength at 1000 ° C. or more and 20 to 60% of organic fibers. A flame-retardant resin is applied to at least one side of the obtained cotton-like material and the whole is matted, and the thickness of the heat insulating sound absorbing material is 8 to 50 mm.
本発明の断熱吸音材において、前記の有機繊維は、無機繊維４０〜８０％に対して、融点が２００℃以上である耐熱性の有機繊維１０〜５０％と、低融点の有機繊維１０〜２５％とで構成すると望ましい。耐熱性の有機繊維は、ポリエステル繊維および／またはナイロン繊維であり、さらに高捲縮繊維または潜在捲縮繊維であると好ましい。 In the heat insulating sound-absorbing material of the present invention, the organic fiber is 10 to 50% heat-resistant organic fiber having a melting point of 200 ° C. or higher and 40 to 25% inorganic fiber and 10 to 25 low-melting organic fiber. % Is desirable. The heat resistant organic fiber is preferably a polyester fiber and / or a nylon fiber, and more preferably a highly crimped fiber or a latent crimped fiber.
本発明の断熱吸音材において、高耐熱性の無機繊維は、シリカ繊維、Ｓガラス繊維、炭化ケイ素繊維、ホウ素繊維、アルミナシリケート繊維、チタン酸アルカリ繊維、セラミック繊維の単独または混合体であり、特にシリカ繊維であると好ましい。また、本発明の断熱吸音材について、それぞれの原料繊維を混綿する前に、あらかじめ撥水剤で処理することも可能である。 In the heat insulating sound-absorbing material of the present invention, the high heat-resistant inorganic fiber is a single fiber or a mixture of silica fiber, S glass fiber, silicon carbide fiber, boron fiber, alumina silicate fiber, alkali titanate fiber, and ceramic fiber. Silica fibers are preferred. In addition, the heat insulating sound-absorbing material of the present invention can be treated in advance with a water repellent before each raw fiber is mixed.
本発明の断熱吸音材をさらに詳細に説明すると、主成分である高耐熱性の無機繊維は、全量の４０〜８０重量％であることが望ましい。高耐熱性の無機繊維は、全量の４０重量％未満であると、他の成分が耐熱性の有機繊維であるならば、高い耐熱・断熱性に関して航空機の新規要求仕様に適合させることが困難になる。一方、全量の４０重量％以上使用すると、航空機の新規要求仕様に適合させるために好適であって一般的に経済的にも有利であるが、８０重量％を超えると断熱吸音材の屈曲性を欠く。 The heat insulating sound absorbing material of the present invention will be described in more detail. It is desirable that the high heat resistant inorganic fiber as the main component is 40 to 80% by weight of the total amount. If the high heat-resistant inorganic fiber is less than 40% by weight of the total amount, it will be difficult to meet the new aircraft requirements for high heat and heat insulation properties if the other components are heat-resistant organic fibers. Become. On the other hand, when 40% by weight or more of the total amount is used, it is suitable for conforming to the new required specifications of the aircraft and is generally economically advantageous. However, if it exceeds 80% by weight, the flexibility of the heat insulating sound absorbing material is improved. Lack.
本発明の断熱吸音材に関して、主成分である高耐熱性の無機繊維は、高温強度を１０００℃以上で維持することを要する。熱溶融温度について、Ｓガラスは１４９３℃およびＥガラスは１１２１℃であるが、Ｅガラス繊維は約８００℃で高温強度が急激に低下するので、ガラス繊維のうちでＳガラス繊維だけが使用可能である。また、ニッケル繊維、タングステン繊維やチタン繊維などの金属繊維および炭素繊維は、高い熱溶融温度の点では使用可能であっても、金属繊維および炭素繊維は一般に熱伝導率が高いので、吸音材の断熱性が低くなってしまう。さらに、ステンレススチール繊維は、融点１０５０℃であっても７００〜８００℃に長時間加熱すると脆化する。 With respect to the heat insulating sound-absorbing material of the present invention, the high heat-resistant inorganic fiber that is the main component is required to maintain the high-temperature strength at 1000 ° C. or higher. Regarding the heat melting temperature, S glass is 1493 ° C. and E glass is 1121 ° C., but E glass fiber is about 800 ° C., and the high-temperature strength rapidly decreases. Therefore, only S glass fiber can be used among the glass fibers. is there. In addition, even though metal fibers such as nickel fibers, tungsten fibers, and titanium fibers and carbon fibers can be used in terms of high heat melting temperature, metal fibers and carbon fibers generally have high thermal conductivity. Thermal insulation will be lowered. Further, even if the stainless steel fiber has a melting point of 1050 ° C., it becomes brittle when heated to 700 to 800 ° C. for a long time.
したがって、好適な高耐熱性の無機繊維として、シリカ繊維、Ｓガラス繊維、炭化ケイ素繊維、ホウ素繊維、アルミナシリケート繊維、チタン酸アルカリ繊維、セラミック繊維の単独または混合体が例示できる。金属繊維は、高耐熱性の無機繊維の一部としてならば、素材として添加できる可能性が残っている。この無機繊維について、特に、シリカ繊維を主体として用いると、コストと物性の点で好ましい。 Accordingly, examples of suitable high heat-resistant inorganic fibers include silica fibers, S glass fibers, silicon carbide fibers, boron fibers, alumina silicate fibers, alkali titanate fibers, and ceramic fibers alone or in a mixture. If metal fibers are part of highly heat-resistant inorganic fibers, there is a possibility that they can be added as raw materials. With regard to this inorganic fiber, it is particularly preferable in terms of cost and physical properties to use silica fiber as a main component.
シリカ繊維は、一般にシリカガラス繊維とも称し、原繊維から可溶性成分や有機分を除去した後に焼成する。例えば、シリカ繊維として、Ｅガラス、ソーダシリカガラス、ホウケイ酸ガラス、ソーダライム系ガラスなどの短繊維をブロー法によって製造し、この短繊維を酸処理して可溶性成分を溶出してから焼成してシリカ骨格を形成させると、例えばシリカ分は約９５％以上に達する。一般に、シリカ繊維の原繊維として、アルカリ含有率１％以下のボロンシリケートガラスであるＥガラス繊維を用いると、コストと物性の点で好ましい。 Silica fibers are generally also called silica glass fibers, and are fired after removing soluble components and organic components from the fibrils. For example, short fibers such as E glass, soda silica glass, borosilicate glass, and soda lime glass are manufactured as a silica fiber by a blow method, and the short fiber is acid-treated to elute soluble components and then fired. When the silica skeleton is formed, for example, the silica content reaches about 95% or more. In general, it is preferable to use E glass fiber, which is boron silicate glass having an alkali content of 1% or less, as silica fiber fibrils in terms of cost and physical properties.
本発明の断熱吸音材において、有機繊維は全量の２０〜６０重量％添加され、該有機繊維を混綿前にあらかじめ難燃剤で処理するか、または得た綿状素材の少なくとも片面に難燃性樹脂を付与することが必要である。このような付加処理を行うことにより、耐熱性にすぎない有機繊維を含んだ断熱吸音材の耐熱性を向上させることができ、航空機に関する新規要求仕様に適合させることが可能になる。 In the heat insulating sound-absorbing material of the present invention, the organic fiber is added in an amount of 20 to 60% by weight, and the organic fiber is treated in advance with a flame retardant before blending, or a flame-retardant resin is provided on at least one side of the obtained cotton-like material. It is necessary to give By performing such an additional treatment, it is possible to improve the heat resistance of the heat-absorbing sound-absorbing material containing organic fibers that are only heat-resistant, and it is possible to meet the new required specifications for aircraft.
有機繊維をあらかじめ難燃剤で処理する場合には、断熱吸音材の難燃性、特に断熱吸音材の表面での延焼性を改良できる。難燃処理で用いる薬剤は特に限定されず、リン窒素系などの難燃剤の水系ディスパージョンを用いることができ、加工性の点から水系のものを用いると好ましい。有機繊維を難燃処理する際には、例えば、市販の水系のリン系難燃剤などをスプレーなどによって所定量付与した後に有機繊維を十分乾燥させ、有機繊維の乾燥が不十分であるとカード性が悪くなる。 When the organic fiber is treated with a flame retardant in advance, it is possible to improve the flame retardancy of the heat insulating sound absorbing material, particularly the fire spreadability on the surface of the heat insulating sound absorbing material. The chemical | medical agent used by a flame retardant process is not specifically limited, The aqueous dispersion of flame retardants, such as a phosphorus nitrogen type | system | group, can be used, and it is preferable to use an aqueous thing from the point of workability. When flame-treating organic fibers, for example, a predetermined amount of commercially available aqueous phosphorus flame retardant is applied by spraying or the like, and then the organic fibers are sufficiently dried. Becomes worse.
添加する有機繊維として、融点が２００℃以上である耐熱性の有機繊維を全量の１０〜５０重量％有することが望ましい。マット加工時に溶融しない耐熱性の有機繊維が１０〜５０重量％存在すると、該断熱吸音材に適切な屈曲性と柔軟性を付与できる。また、カード通過性などによるカード形成度合いが良くなり、原料の歩留まりが向上する。耐熱性の有機繊維が全量の１０重量％未満であると、適当な屈曲性と柔軟性を付与できず、一方、全量の５０重量％を超えると断熱吸音材の耐熱性が低下し、航空機に関する新規要求仕様に適合させるのが困難になる。 As the organic fiber to be added, it is desirable to have 10 to 50% by weight of the heat-resistant organic fiber having a melting point of 200 ° C. or higher. If 10 to 50% by weight of heat-resistant organic fibers that do not melt during mat processing are present, it is possible to impart appropriate flexibility and flexibility to the heat insulating sound-absorbing material. Further, the degree of card formation due to the card passing property is improved, and the yield of raw materials is improved. When the heat-resistant organic fiber is less than 10% by weight of the total amount, appropriate flexibility and flexibility cannot be imparted. On the other hand, when it exceeds 50% by weight of the total amount, the heat resistance of the heat insulating sound absorbing material decreases, and It becomes difficult to meet new requirements.
好適な耐熱性の有機繊維として、ポリエステル繊維、ナイロン繊維の単独または混合体が例示できる。さらに、この有機繊維が高捲縮繊維または潜在捲縮繊維であると、いっそう嵩高い断熱吸音材を得ることができる。 Examples of suitable heat-resistant organic fibers include polyester fibers and nylon fibers, either alone or as a mixture. Furthermore, if this organic fiber is a highly crimped fiber or a latent crimped fiber, a more bulky heat insulating sound absorbing material can be obtained.
添加する有機繊維には、さらに低融点の有機繊維が全量の１０〜２５重量％含まれることが望ましい。低融点の有機繊維を均一に混綿することにより、これが次工程の熱処理によって溶融されて綿状素材のマット化を達成するので、この熱処理は該有機繊維の融点よりも高い温度で行うことを要する。低融点の有機繊維が１０重量％未満であると、硬綿状のマット材を得ることが困難になり、一方、２５重量％を超えると、耐熱性が低下するとともに断熱試験時に発煙やガスが発生しやすく、航空機に関する吸音材の新規要求仕様に不合格になってしまう。 It is desirable that the organic fibers to be added contain 10 to 25% by weight of the total amount of organic fibers having a low melting point. By uniformly blending the low melting point organic fiber, it is melted by the heat treatment of the next step to achieve matting of the cotton-like material, so this heat treatment needs to be performed at a temperature higher than the melting point of the organic fiber. . If the organic fiber having a low melting point is less than 10% by weight, it becomes difficult to obtain a hard cotton mat material. On the other hand, if it exceeds 25% by weight, the heat resistance is lowered and smoke or gas is generated during the heat insulation test. It is likely to occur and it will fail the new requirements for sound-absorbing materials for aircraft.
この低融点の有機繊維は、一般に、融点が１１０〜１５０℃前後であるポリエステル、ポリプロピレン、アクリルのような熱可塑性繊維またはこれらの複合繊維などである。好ましくは、低融点の有機繊維と高融点の有機繊維との複合繊維が芯鞘型や並列型などの２層型であり、熱処理時の加熱温度で低融点の有機繊維だけが溶融し、その温度で高融点の有機繊維は形状を維持できるから、繊維自体の原形が保たれることで綿状素材のマット化を確実に達成できる。 The low melting point organic fiber is generally a thermoplastic fiber such as polyester, polypropylene, or acrylic having a melting point of about 110 to 150 ° C. or a composite fiber thereof. Preferably, the composite fiber of the low melting point organic fiber and the high melting point organic fiber is a two-layer type such as a core-sheath type or a parallel type, and only the low melting point organic fiber melts at the heating temperature during the heat treatment. Since the organic fiber having a high melting point at the temperature can maintain its shape, matting of the cotton-like material can be reliably achieved by maintaining the original shape of the fiber itself.
無機繊維および有機繊維からなる原料繊維について、あらかじめ撥水剤で処理してから、カードウェブを形成することも可能であり、この撥水処理を前記の難燃処理と同時に行うことも可能である。原料繊維をあらかじめ撥水処理しておくと、綿状素材を後から撥水処理する場合よりも嵩高な素材を得ることができる。ここで用いる撥水剤は特に限定されず、水系または溶剤系であるフッ素系やシリコーン系などの撥水剤を用いることができ、加工性の点から水系のものを用いると好ましい。原料繊維を撥水処理する際には、例えば、市販の水系のフッ素系撥水剤をスプレーなどによって所定量付与した後に、原料繊維を十分乾燥させ、カード機に通してウェブを完成させる。この際に、原料繊維の乾燥が不十分であると、カード性が不良になるので注意すべきである。 It is also possible to form a card web after previously treating with a water repellent for raw fibers made of inorganic fibers and organic fibers, and this water repellent treatment can be performed simultaneously with the above flame retardant treatment. . When the raw fiber is subjected to a water repellent treatment in advance, a bulky material can be obtained as compared with a case where the cotton-like material is subjected to a water repellent treatment later. The water repellent used here is not particularly limited, and water-based or solvent-based fluorine-based or silicone-based water repellents can be used, and water-based ones are preferable from the viewpoint of workability. When the raw fiber is subjected to water repellent treatment, for example, a predetermined amount of commercially available water-based fluorine-based water repellent is applied by spraying or the like, and then the raw material fiber is sufficiently dried and passed through a card machine to complete the web. At this time, it should be noted that if the raw material fibers are not sufficiently dried, the card property becomes poor.
有機繊維の予備的難燃処理の代わりに、得た断熱吸音材の片面または両面に、スプレー、ロールコーティングまたはディッピングなどによって難燃性樹脂を施してもよい。この難燃加工に用いる樹脂バインダーは、一般に、ポリエステルやアクリルのような耐熱性の熱可塑性樹脂の水性ディスパージョンにリン系難燃剤を加え、さらに界面活性剤を加えて安定化させる。塗布される樹脂の量は、０.５〜５０ｇ／ｍ２であり、好ましくは２〜２０ｇ／ｍ２である。塗布された樹脂は、次工程の熱処理によって乾燥して断熱吸音材のマット化を促進する。 Instead of the preliminary flame retardant treatment of the organic fiber, a flame retardant resin may be applied to one side or both sides of the obtained heat insulating sound absorbing material by spraying, roll coating or dipping. The resin binder used for this flame retardant processing is generally stabilized by adding a phosphorus-based flame retardant to an aqueous dispersion of a heat-resistant thermoplastic resin such as polyester or acrylic and further adding a surfactant. The amount of resin applied is 0.5 to 50 g / m 2 , preferably 2 to 20 g / m 2 . The applied resin is dried by the heat treatment in the next step to promote matting of the heat insulating sound absorbing material.
原料繊維の予備的撥水処理の代わりに、マット化のための溶融熱処理の前または後に、得た硬綿状のマット材を撥水加工してもよく、用いる撥水剤は無機および／または有機の市販品であり、例えば、水性のフッ素樹脂である。この撥水加工は、スプレー、ロールコーティングまたはディッピングなどのいずれによって行ってもよい。この撥水加工は、前記の難燃加工と同時に行うこともできる。 Instead of the preliminary water repellent treatment of the raw fibers, the hard cotton mat material obtained may be water repellent before or after the melt heat treatment for matting, and the water repellent used may be inorganic and / or Organic commercial products, for example, aqueous fluororesins. This water repellent process may be performed by spraying, roll coating or dipping. This water-repellent processing can be performed simultaneously with the flame-retardant processing.
得た断熱吸音材は、厚さが８〜５０ｍｍであると好ましい。この厚さが８ｍｍ未満であると、厚みが薄すぎるので自動車や航空機などへの内装作業が煩雑になり、厚さが５０ｍｍを超えると、断熱吸音材を曲げにくくなるので内装作業がやはり難しくなる。マット化した断熱吸音材について、さらにニードルパンチング、毛焼きまたはカレンダーによって表面平滑化処理を施すことが可能である。特に、ニードルパンチングで処理すると、断熱吸音材の強度を向上させることができるので好ましい。 The obtained heat-absorbing sound-absorbing material preferably has a thickness of 8 to 50 mm. If this thickness is less than 8 mm, the thickness is too thin and the interior work for automobiles and aircraft becomes complicated. If the thickness exceeds 50 mm, the heat insulating sound absorbing material becomes difficult to bend, so the interior work is still difficult. . The matted heat-absorbing sound-absorbing material can be further subjected to a surface smoothing treatment by needle punching, hair burning or calendering. In particular, the treatment by needle punching is preferable because the strength of the heat insulating sound absorbing material can be improved.
本発明の断熱吸音材において、無機繊維の織布またはフェルトからなる表面シートをマット材に不燃性樹脂で貼り合わせてもよい。この表面シートは、ガラス繊維、炭素繊維またはセラミック繊維などからなり、マット材自体は前記と同様である。この表面シートを貼り合わせると、航空機または鉄道車両への施工時に裁断したり折り曲げても、マット材からガラス繊維などの繊維粉末の落下が少なくなるので作業が容易になる。 In the heat insulating sound-absorbing material of the present invention, a surface sheet made of woven fabric or felt of inorganic fibers may be bonded to the mat material with a non-combustible resin. This surface sheet is made of glass fiber, carbon fiber, ceramic fiber, or the like, and the mat material itself is the same as described above. When this surface sheet is bonded, even if it is cut or bent during construction on an aircraft or a railway vehicle, the fiber powder such as glass fiber is less dropped from the mat material, so that the operation becomes easy.
航空機に用いる新規要求仕様のマット材の耐火性（ＦＡＲ２５.８５６（ｂ）に規定）は、４分間で背面熱量が２Ｗ／ｃｍ２以下であり、耐熱温度は規定されていないが、ＦＡＲ２５.８５６（ｂ）に既定の条件を充足させるため、約１１００℃で４分間耐えることを要する。本発明の断熱吸音材は、より厳しい航空機に関する不織布の新規要求仕様にも適合している。 The fire resistance (specified in FAR 25.856 (b)) of the newly required mat material used for aircraft has a back heat amount of 2 W / cm 2 or less in 4 minutes, and the heat resistance temperature is not specified, but FAR 25.856. In order to satisfy the predetermined condition in (b), it is necessary to endure at about 1100 ° C. for 4 minutes. The heat insulating sound-absorbing material of the present invention also meets the new requirements for nonwoven fabrics related to stricter aircraft.
本発明に係る断熱吸音材は、マット材の主成分が高耐熱性の無機繊維であって有機成分が耐熱性であることにより、ほぼ完全に不燃性であり且つ断熱性と吸音性が高く、各種の自動車や鉄道車両用の吸音材として使用できることはもとより、より厳しい航空機に関する不織布の新規要求仕様にも適合している。本発明の断熱吸音材は、より厳しい航空機の新規要求仕様に適合することにより、自動車、鉄道車両、航空機などに取り付けた際に従来よりも安全性が高くなり、航空機用として多量に納品することが期待できるうえに、鉄道車両に関して英国規格に準拠する諸外国における高速鉄道の車両にも十分に適用できる。 The heat insulating sound-absorbing material according to the present invention is almost completely non-flammable and has high heat-insulating and sound-absorbing properties because the main component of the mat material is inorganic fibers with high heat resistance and the organic component is heat resistant. Not only can it be used as a sound-absorbing material for various automobiles and railway vehicles, it also meets new requirements for nonwoven fabrics for stricter aircraft. The heat-insulating sound-absorbing material of the present invention is more safe when installed in automobiles, railway vehicles, airplanes, etc. by conforming to new and more demanding specifications for aircraft, and delivered in large quantities for aircraft. In addition, it can be fully applied to high-speed railway vehicles in other countries that conform to British standards for railway vehicles.
本発明の断熱吸音材は、比較的剛直な高耐熱性の無機繊維に対して比較的柔軟な耐熱性の有機繊維を添加し、吸音材の設置の際に屈曲させることが可能である。本発明の断熱吸音材では、低融点の有機繊維を少量均一に混綿することにより、熱処理だけで全体が均一なマット材に加工でき、後加工時に構成繊維が折損することが少ない。本発明の断熱吸音材は、柔軟で扱いやすいマット材であり、施工時に裁断したり屈曲させても繊維脱落が少なく、作業環境を悪化させることが少ない。 The heat insulating sound-absorbing material of the present invention can be bent when a sound-absorbing material is installed by adding a relatively soft heat-resistant organic fiber to a relatively rigid high-heat-resistant inorganic fiber. In the heat insulating sound-absorbing material of the present invention, a small amount of organic fiber having a low melting point is uniformly mixed, so that the whole can be processed into a uniform mat material only by heat treatment, and the constituent fibers are less likely to break during post-processing. The heat-insulating sound-absorbing material of the present invention is a mat material that is flexible and easy to handle. Even if it is cut or bent at the time of construction, there is little fiber dropout and the working environment is hardly deteriorated.
次に、本発明を実施例に基づいて説明するが、本発明は実施例に限定されるものではない。以下では、断熱吸音材の製造について説明する。 Next, the present invention will be described based on examples, but the present invention is not limited to the examples. Below, manufacture of a heat insulation sound-absorbing material is demonstrated.

When the heat resistance, water repellency, and fire spreadability of the obtained mat material were evaluated, all were acceptable levels.
