Description
本発明は断熱材、断熱構造体、排ガス浄化装置およびその製造方法に関する。特に、自動車エンジン等の内燃機関から排出される排気ガスを排出するための排気管等を保温するために使用さる断熱材、これを使用した断熱構造体、排ガス浄化装置およびこれらの製造方法に関する。 The present invention relates to a heat insulating material, a heat insulating structure, an exhaust gas purification device, and a method for manufacturing the same. In particular, the present invention relates to a heat insulating material used to keep an exhaust pipe or the like for discharging exhaust gas discharged from an internal combustion engine such as an automobile engine, a heat insulating structure using the heat insulating material, an exhaust gas purifying apparatus, and a method for manufacturing them.
ディーゼルエンジン、ガソリンエンジン等の内燃機関から排出される排ガス中にはＰＭ（パティキュレートマター）が含まれており、近年、このＰＭが人体や環境に悪影響を及ぼすことが問題となっている。また、排ガス中には、ＣＯ、ＨＣ、ＮＯｘ等の有害なガス成分も含まれていることから、この有害なガス成分が人体や環境に及ぼす影響についても懸念されている。 Exhaust gas discharged from internal combustion engines such as diesel engines and gasoline engines contains PM (particulate matter), and in recent years, it has been a problem that this PM adversely affects the human body and the environment. Also, in the exhaust gas, CO, HC, since it is also contain toxic gas components such as NO x, are also concerned impact of this toxic gas components on the human body and the environment.
そこで、排ガス中のＰＭを補修したり、有害なガス成分を浄化したりする排ガス浄化装置として、炭化ケイ素やコージェライトなど多孔質セラミックからなる排ガス処理体と、排ガス処理体を収容するケーシングと、排ガス処理体とケーシングとの間に配設される無機繊維集合体からなる保持シール材とから構成される排ガス浄化装置が種々提案されている。この保持シール材は、自動車の走行等により生じる振動や衝撃により、排ガス処理体がその外周を覆うケーシングと接触して破損するのを防止することや、排ガス処理体とケーシングとの間から排気ガスが漏れることを防止すること等を主な目的として配設されている。 Therefore, as an exhaust gas purification device that repairs PM in exhaust gas or purifies harmful gas components, an exhaust gas treatment body made of porous ceramics such as silicon carbide and cordierite, and a casing that houses the exhaust gas treatment body, Various exhaust gas purifying apparatuses composed of a holding sealing material made of an inorganic fiber aggregate disposed between an exhaust gas treating body and a casing have been proposed. This holding sealing material prevents the exhaust gas treating body from being damaged by contact with the casing covering the outer periphery due to vibrations or impacts caused by traveling of an automobile or the like, and exhaust gas from between the exhaust gas treating body and the casing. Is disposed mainly for the purpose of preventing leakage.
また、この排ガス浄化装置は、排ガス処理体の排ガス処理性能を有効に機能させるために、排ガス処理体を保温する保温性能が求められる。前述のＰＭを捕獲するためのＤＰＦ（ディーゼルパティキュレートフィルター）においては、フィルター内に堆積したＰＭを燃焼させる再生処理を行う際に、ＤＰＦが保温されていることで、効果的にＰＭを燃焼させることができる。また、触媒機能を有する排ガス処理体においては、触媒活性温度以上に温度を保つために余剰な燃料噴射を必要とするが、排ガス処理体を保温することにより、燃料噴射を抑えることができ、燃費を改善することができる。 In addition, the exhaust gas purification device is required to have a heat retaining performance for keeping the exhaust gas treating body warm in order to effectively function the exhaust gas treating performance of the exhaust gas treating body. In the DPF (diesel particulate filter) for capturing PM described above, when the regeneration process for burning the PM accumulated in the filter is performed, the DPF is kept warm, so that the PM is effectively burned. be able to. Further, in the exhaust gas treating body having a catalytic function, excessive fuel injection is required to keep the temperature above the catalyst activation temperature. However, by keeping the exhaust gas treating body warm, fuel injection can be suppressed, and fuel consumption can be reduced. Can be improved.
排ガス処理体の保温手段として、従来は、排気管シェルに対して半円状に分割した断熱材とメタルカバーとを組合せて、カバー断熱構造を形成し、断熱材とメタルカバーを予め嵌め込んで、排気管シェルへ取り付けることが行われている。また、特許文献１では３次元成形体で触媒保持とコーン断熱を行うことが提案されている。
しかしながら、複数に分割したカバー断熱構造では、断熱材を組み付ける際に位置ずれが生じやすく、また、その修正に時間を要する。また、３次元成形体では、異なる形状の配管シェルごとに異なる３次元の型を必要とするため、コスト増の要因となる。また、３次元形状であるため嵩張るため、梱包、搬送時の積載効率が悪いという問題がある。
Conventionally, as a heat insulation means for the exhaust gas treatment body, a heat insulating material divided into a semicircular shape with respect to the exhaust pipe shell and a metal cover are combined to form a cover heat insulating structure, and the heat insulating material and the metal cover are fitted in advance. Attach to the exhaust pipe shell. Patent Document 1 proposes to perform catalyst holding and cone heat insulation with a three-dimensional molded body.
However, in the cover heat insulating structure divided into a plurality of parts, positional displacement is likely to occur when the heat insulating material is assembled, and it takes time to correct the heat insulating material. In addition, a three-dimensional molded body requires a different three-dimensional mold for each pipe shell having a different shape, which causes an increase in cost. Moreover, since it is a three-dimensional shape, it is bulky, and there is a problem that the loading efficiency during packing and transportation is poor.
そこで、本発明は上記のような従来技術が有する問題点を解決し、排ガス等が通過する金属からなる管状構造体の保温手段として、断熱性能に優れ、かつ排ガス処理体への取り付時にずれが生じることなく作業性が良く、かつ梱包、搬送時に嵩張らない構造を有する断熱材を提供することを目的とする。 Therefore, the present invention solves the problems of the prior art as described above, and as a heat retaining means for a tubular structure made of a metal through which exhaust gas passes, it has excellent heat insulation performance and is displaced when attached to an exhaust gas treatment body. An object of the present invention is to provide a heat insulating material that has a good workability without causing any problems and has a structure that is not bulky during packaging and transportation.

本発明の実施形態を図面に基づいて詳細に説明する。図１は本発明の断熱材の平面図（a）と平面図（ａ）のＡ−Ａ線に沿った断面図（ｂ）を模式的に表したものである。図１（ａ）に示すように、本実施形態の断熱材は無機繊維を含む複数の短冊状マット材１１〜２４が織り合せられた織物構造体から構成される。図１（ａ）において複数の短冊状マット材は第一の方向に延伸する第一の短冊群１１、１２、１３、１４と第一の方向と交差する第二の短冊群２１、２２、２３、３４から構成されている。図１（ｂ）に示すように、第一の短冊群中の一部の短冊状マット材１１、１２、１３、１４と第二の短冊群中の一部２３の短冊状マット材が織物構造体の表面に交互に現れている。 Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 schematically shows a plan view (a) of a heat insulating material of the present invention and a cross-sectional view (b) along the line AA of the plan view (a). As shown to Fig.1 (a), the heat insulating material of this embodiment is comprised from the textile fabric structure by which the several strip-shaped mat materials 11-24 containing an inorganic fiber were interwoven. In FIG. 1 (a), the plurality of strip-shaped mat members are first strip groups 11, 12, 13, and 14 extending in the first direction and second strip groups 21, 22, and 23 that intersect the first direction. , 34. As shown in FIG. 1B, a part of the strip-shaped mat members 11, 12, 13, 14 in the first strip group and a part of the strip-shaped mat member 23 in the second strip group are woven structures. It appears alternately on the surface of the body.
短冊状マットの一部とは、短冊状マットが一つの場合と複数並列した場合を含むことを意味しており、図１では、第一方向の短冊状マットと第二方向の短冊状マットが一つずつ表面に交互に現れている場合を示したが、複数の並列した短冊状マットが表面に交互に現れていてもよい。このように、織物構造体の表面に短冊状マットが交互に現れる構造により、表面に凹凸が形成され、管状構造体の取り付時に摩擦によりずれが生じにくくなる。また、このように形成された織物構造体は伸縮性があり、管状構造体に巻きつけ後長手方向に伸ばすことにより、管状構造体に固定しやすくなる。 A part of the strip-shaped mat means that there are one strip-shaped mat and a plurality of strip-shaped mats arranged in parallel. In FIG. 1, the strip-shaped mat in the first direction and the strip-shaped mat in the second direction are included. Although the case where it alternately appears on the surface one by one has been shown, a plurality of parallel strip-like mats may alternately appear on the surface. In this way, the structure in which strip-like mats appear alternately on the surface of the woven structure forms irregularities on the surface, and is less likely to be displaced due to friction when the tubular structure is attached. Moreover, the woven structure formed in this way has elasticity, and it becomes easy to fix to a tubular structure by winding around a tubular structure and extending in a longitudinal direction.
断熱材を構成する短冊状マット材は無機繊維を含む。無機繊維としては、特に限定されないが、例えば、アルミナ繊維、アルミナ−シリカ繊維、シリカ繊維、生体溶解性繊維等が挙げられる。このような無機繊維を使用することにより、短冊状マットは保持性に優れ、無機繊維の機械的特性にも優れているので、マットに亀裂や圧壊が発生しにくく、金属からなる管状構造体がしっかりと保持される。また、コロイダルシリカ、アルミナゾル、チタニアゾル、ジルコニア等の無機バインダーを含んでもよい。さらに、例えば、ポリアクリルアミド等のアクリル樹脂、デンプン、エマルジョン、ラテックス等の有機バインダーを含んでもよい。 The strip-shaped mat material constituting the heat insulating material includes inorganic fibers. Although it does not specifically limit as an inorganic fiber, For example, an alumina fiber, an alumina-silica fiber, a silica fiber, a biosoluble fiber etc. are mentioned. By using such an inorganic fiber, the strip-shaped mat has excellent holding properties and excellent mechanical properties of the inorganic fiber, so that the mat is not easily cracked or crushed. Holds firmly. Further, it may contain an inorganic binder such as colloidal silica, alumina sol, titania sol, zirconia. Further, for example, an acrylic resin such as polyacrylamide, and an organic binder such as starch, emulsion, and latex may be included.
本発明の一実施形態の断熱材においては、短冊状マット材にニードルパンチが施すことができる。ニードルパンチとは、ニードル等の繊維交絡手段を素地マットに対して抜き差しすることをいう。マット材にニ―ドルパンチ処理を施すことにより、無機繊維どうしの交絡が発生し、マットの強度が向上する。そのため、マットに亀裂や圧壊が発生しにくくなる。
本発明の短冊状マット材は、例えば抄造法を用いて製作することができる。抄造法とは、通常湿式処理とも呼ばれ、いわゆる「紙抄き」のように、繊維の混合、撹拌、開繊、スラリー化、抄紙成形、圧縮乾燥の各処理を経て保持シール材を製作する処理方法である。
In the heat insulating material of one embodiment of the present invention, needle punch can be applied to the strip-shaped mat material. Needle punching means that fiber entanglement means such as a needle is inserted into and removed from the base mat. By subjecting the mat material to a needle punch treatment, entanglement of inorganic fibers occurs, and the strength of the mat is improved. Therefore, cracks and crushing are less likely to occur in the mat.
The strip-shaped mat material of the present invention can be manufactured using, for example, a papermaking method. The paper making method is usually called wet processing, and a holding sealing material is manufactured through fiber mixing, stirring, fiber opening, slurrying, paper making, and compression drying, as in the so-called “paper making”. It is a processing method.
まず、所定量の無機繊維原料と結合材を水に入れて、混合する。
次に得られた混合物を抄紙器等の混合器内で撹拌し、開繊されたスラリーを調製する。通常、撹拌開繊処理は、２０秒〜１２０秒程度行われる。その後、得られたスラリーを成型器に入れて所望の形状に成形し、さらに脱水を行うことにより短冊状マット材の原料マットが得られる。
さらにこの原料マットをプレス器等を用いて圧縮し、例えば９０〜１５０℃の温度で加熱、乾燥させることにより、マット材を得ることができる。なお通常、圧縮処理は、圧縮後の保持シール材の密度が０．１０ｇ／ｃｍ３〜０．４０ｇ／ｃｍ３程度となるように行われる。
このようにして製作されたマット材を裁断することによって短冊状マット材を得ることができる。
First, a predetermined amount of inorganic fiber raw material and a binder are put in water and mixed.
Next, the obtained mixture is stirred in a mixer such as a paper machine to prepare a spread slurry. Usually, the stirring and opening process is performed for about 20 seconds to 120 seconds. Thereafter, the obtained slurry is put into a molding machine to be molded into a desired shape, and further dewatered to obtain a raw mat for a strip mat material.
Furthermore, the mat material can be obtained by compressing the raw material mat using a press or the like, and heating and drying at a temperature of 90 to 150 ° C., for example. Note Usually, the compression process, the density of the holding sealing material after compression is performed such that the 0.10g / cm 3 ~0.40g / cm 3 order.
A strip-shaped mat material can be obtained by cutting the mat material thus manufactured.
断熱材は、織物構造体が単層であってもよく、複数積層されて構成されてもよい。複数層を積層する場合、上下の層において短冊状マットが表面に現れる部分と現れない部分の位置関係がずれていてもよい。
本発明の一実施形態の断熱材において、短冊状マット材の表面の少なくとも一部には繊維飛散抑制部が設けられていてもよい。短冊状マットはマット材を裁断することにより形成した場合、裁断部の端面（側面）から無機繊維が飛散する可能性がある。このため、短冊状マットの表面の一部または全部に飛散抑制部を設けることができる。飛散抑制部の形成方法としては、例えば、マット材の表面にアルミ箔を蒸着、接着してから短冊状マットに裁断する方法や、短冊状マットの表面の一部または全部に無機系バインダーを塗布するなどの方法がある。無機系バインダーとしては、通常のコロイダルシリカ、アルミナゾル、チタニアゾル等が挙げられる。
The heat insulating material may be a single layer of the woven structure or may be configured by laminating a plurality of layers. When a plurality of layers are stacked, the positional relationship between the portion where the strip-like mat appears on the surface and the portion where it does not appear in the upper and lower layers may be shifted.
In the heat insulating material according to the embodiment of the present invention, a fiber scattering suppressing portion may be provided on at least a part of the surface of the strip-shaped mat material. When the strip mat is formed by cutting a mat material, inorganic fibers may be scattered from the end face (side face) of the cut portion. For this reason, a scattering suppression part can be provided in part or all of the surface of a strip-shaped mat. Examples of the method for forming the scattering suppression part include a method of vapor-depositing and bonding an aluminum foil on the surface of the mat material and then cutting it into a strip-shaped mat, or applying an inorganic binder to part or all of the surface of the strip-shaped mat. There are ways to do it. Examples of the inorganic binder include ordinary colloidal silica, alumina sol, titania sol and the like.
断熱材の織物構造体は筒状であってもよい。短冊状マット材を筒状に織込むことによって、金属からなる管状構造体を筒状の織物構造体中に挿入することにより容易に装着することができる。管状構造体を筒状の織物構造体に挿入後、織物構造体の端部に外側から、フック材によって固定することができる。また、断熱材の織物構造体は平板状であってもよい。この場合は、金属からなる管状構造体に平板状の織物構造体を巻き付け、紐、ホースクランプ等のフック材を使用するか、またはその他の方法によって管状構造体に適宜固定することができる。 The woven fabric structure of the heat insulating material may be cylindrical. By weaving the strip-shaped mat material into a cylindrical shape, it can be easily mounted by inserting a tubular structure made of metal into the tubular woven structure. After the tubular structure is inserted into the tubular woven structure, it can be fixed to the end of the woven structure by a hook material from the outside. The woven fabric structure of the heat insulating material may be flat. In this case, a flat woven structure can be wound around a tubular structure made of metal, and a hook material such as a string or a hose clamp can be used, or can be appropriately fixed to the tubular structure by other methods.
この断熱材は、無機繊維を含む複数の短冊状マット材が織り合せられた織物構造体から構成されているため、種々の形状の排気管等に柔軟に装着することができる。例えば、図２（ａ）に示されるように、排ガス浄化装置のコーン部などの径が異なる部位にもシェル部と一体で巻きつけることができ、巻きつけ後、図２（ｂ）に示されるように、織物構造体を長手方向（管状構造体の軸方向）に引き伸ばすことにより、偏芯コーンに対しても柔軟に対応することができる。 Since this heat insulating material is composed of a woven fabric structure in which a plurality of strip-shaped mat members containing inorganic fibers are interwoven, it can be flexibly attached to various shapes of exhaust pipes and the like. For example, as shown in FIG. 2 (a), the shell portion can also be wound integrally with a portion having a different diameter, such as a cone portion of the exhaust gas purifying apparatus, and after winding, the portion is shown in FIG. 2 (b). As described above, by stretching the woven structure in the longitudinal direction (the axial direction of the tubular structure), it is possible to flexibly cope with the eccentric cone.
断熱材としての織物構造体の端部には、織物構造体を端部において締め付可能なフック部があらかじめ配設されていてもよい。フック部としては、図３（ａ）に示されるように織物構造体の端部３１に紐が挿入される構造として、金属からなる管状構造体を挿入後、この紐に沿って筒状の織物構造体の端部を縮めることで金属構造体に固定する方法がある。この場合、紐３２は織物構造体の端部に固着されず、紐の長手方向に移動可能な状態とする。 A hook portion capable of fastening the fabric structure at the end portion may be provided in advance at the end portion of the fabric structure as the heat insulating material. As the hook portion, as shown in FIG. 3 (a), as a structure in which a string is inserted into the end 31 of the fabric structure, a tubular structure made of metal is inserted, and then a tubular fabric is formed along the string. There is a method of fixing to a metal structure by shrinking an end of the structure. In this case, the string 32 is not fixed to the end portion of the woven structure, and is movable in the longitudinal direction of the string.
また、断熱材としての織物構造体の端部は、図４（ｂ）および（ｃ）に見られるように短冊状マットの端部がそれぞればらばらの状態でもよいし、短冊状マット間を固定するために、図３（ａ）に示される紐３１を織物構造体（短冊状マット）の端部３１に接着剤などにより固定して形成してもよい。あるいは、図３（ｂ）に示されるように、金属等の留め具（ピン）３３によって固定してもよい。 Further, as shown in FIGS. 4B and 4C, the end portions of the woven fabric structure as the heat insulating material may be in a state where the end portions of the strip mats are separated from each other, and the end portions of the strip mats are fixed. For this purpose, the string 31 shown in FIG. 3A may be formed by being fixed to the end 31 of the woven structure (strip-shaped mat) with an adhesive or the like. Or as shown in Drawing 3 (b), you may fix with fasteners (pins) 33, such as metal.
断熱材としての織物構造体を構成する短冊状マット材の幅、厚み、および短冊状マット間の隙間は適宜決めることができるが、例えば、幅は、５〜５０ｍｍ、厚みは１〜２５ｍｍとすることができる。短冊状マットの幅は第一方向と第二方向で異なっていてもよい。特に、断熱材の伸縮性は短冊状マット材の幅およびその隙間の関係で調整することができる。以下、この点について、図２を参照して説明する。図２（ａ）は短冊状マットからなる織物構造体２６をコーン部とシェル部を有する管状構造体２５に巻きつけた状態（引き伸ばす前）示しており、図２（ｂ）は巻きつけ後、織物構造体２６を管状構造体２５の長手方向に引き伸ばした状態を示している。 The width and thickness of the strip-shaped mat material constituting the woven fabric structure as the heat insulating material and the gap between the strip-shaped mats can be appropriately determined. For example, the width is 5 to 50 mm, and the thickness is 1 to 25 mm. be able to. The width of the strip-shaped mat may be different between the first direction and the second direction. In particular, the stretchability of the heat insulating material can be adjusted by the relationship between the width of the strip-shaped mat material and the gap between the materials. Hereinafter, this point will be described with reference to FIG. FIG. 2A shows a state in which a woven fabric structure 26 made of a strip mat is wound around a tubular structure 25 having a cone portion and a shell portion (before stretching), and FIG. 2B shows a state after winding. A state in which the woven structure 26 is stretched in the longitudinal direction of the tubular structure 25 is shown.
本発明の一実施形態の織物構造体は、図２（ａ）および（ｂ）に示されるように、複数の短冊状マット材は第一の方向に延伸する第一の短冊群１と第一の方向と交差する第二の短冊群２から構成されるが、織物構造体２６を排気管２５に被せる際の長手方向をＸ軸、径方向をＹ軸とし、Ｘ軸と第一の方向との角度をθとする。また、全ての短冊状マットの幅を均一にｄ、全ての短冊状マット間の隙間を均一にｓとすると、近接した４つの交点を結んで形成される平行四辺形の一辺の長さはｄ＋ｓとなり、対角線の長さは、
Ｘ方向の対角線の長さ ２（ｄ＋ｓ）ｃｏｓθ・・・・（１）
Ｙ方向の対角線の長さ ２（ｄ＋ｓ）ｓｉｎθ・・・・（２）
となり、断熱材の現か伸び量は、式（２）の対角線の長さが短冊幅以下にならないことから、限界伸びとなるときの最小角度θlimitは、
２（ｄ＋ｓ）×（ｓｉｎθlimit）＝ｄ・・・・（３）となり、
θlimit＝ｓｉｎ―１（ｄ／２（ｄ＋ｓ））・・・・（４）で求められる。
As shown in FIGS. 2 (a) and 2 (b), the fabric structure of one embodiment of the present invention includes a first strip group 1 and a first strip group 1 in which a plurality of strip-like mat members extend in a first direction. Is composed of a second strip group 2 that intersects the direction of the X direction, the longitudinal direction when the fabric structure 26 is covered on the exhaust pipe 25 is the X axis, the radial direction is the Y axis, and the X axis and the first direction Is the angle θ. If the width of all strip mats is uniformly d and the gap between all strip mats is uniformly s, the length of one side of the parallelogram formed by connecting four adjacent intersections is d + s. And the length of the diagonal line is
Length of diagonal line in X direction 2 (d + s) cos θ (1)
Length of diagonal line in Y direction 2 (d + s) sin θ (2)
Since the length of the diagonal line of the formula (2) is not less than the width of the strip, the minimum angle θ limit when the limit elongation is
2 (d + s) × (sin θ limit ) = d (3)
θ limit = sin −1 (d / 2 (d + s)) (4)
また、図２（ａ）に示されるように、織物構造体を引き伸ばす前の最初のθをθ０とすると、織物構造体の長手方向の伸び率（短冊状マットの最大長さ（最大伸び）となるときの織物構造体の長手方向の伸び率は（ｃｏｓθlimit）／（ｃｏｓθ０）、織物構造体の径方向の縮小率（短冊状マットの幅の縮小率）は（ｓｉｎθlimit）／(ｓｉｎθ０)で表される。 Further, as shown in FIG. 2 (a), when the initial θ before stretching the fabric structure is θ 0 , the elongation rate in the longitudinal direction of the fabric structure (maximum length of strip mat (maximum elongation)) The elongation ratio in the longitudinal direction of the woven structure is (cos θ limit ) / (cos θ 0 ), and the reduction ratio in the radial direction of the woven structure (reduction ratio of the width of the strip-shaped mat) is (sin θ limit ) / ( sin θ 0 ).
以上より、短冊状マットの幅ｄが小さく、短冊状マット間の隙間ｓが大きくなるほど変形しやすくなることがわかる。したがって、排気管の形状、寸法に応じて、短冊状マットの幅ｄと短冊状マット間の隙間ｓを調整することにより、排気管に適応した織物構造体の設計が可能となる。ただし、隙間ｓが大きいと断熱材による被覆面積が減少し（開口率が大きくなる）、断熱性が損なわれる点に配慮する必要がある。 From the above, it can be seen that the shorter the width d of the strip mat and the larger the gap s between the strip mats, the easier the deformation. Therefore, by adjusting the width d of the strip mat and the gap s between the strip mats according to the shape and dimensions of the exhaust pipe, it is possible to design a fabric structure adapted to the exhaust pipe. However, it is necessary to consider that when the gap s is large, the area covered with the heat insulating material is reduced (opening ratio is increased), and the heat insulating property is impaired.
保持シール材を構成する短冊状マットの第一方向と第二方向の金属からなる管状構造体の長手方向に対する角度（上記θ０）は４５°であってもよい。また、同角度（上記θ０）は４５°未満であっても、４５°を超えていてもよい。
本発明の一実施形態の織物構造体を金属からなる管状構造体の周囲に装着した際の、伝熱状態のイメージを図５に示した。管状構造体５１を通過する排ガスにより発生した熱は管状構造体５１から断熱材の織物構造５２を伝わり放熱される。図５に示されるように織物構造５２は管状構造体５１との接触面積が小さくなり、熱が逃げる接点が少なくなる上に、短冊状マットの交差点から交差点への伝熱については距離が長くなり、伝熱しにくくなる。ここで、図２に示した短冊状マットの幅ｄと短冊状マット間の隙間ｓを用いると、管状構造体５１と断熱材５２の接点の面積率はｄ２／（ｓ＋ｄ）２となり、隙間ｓを大きくすることで接点の面積率を小さくすることができる。したがって、例えば、管状構造体が自動車用の排ガス浄化装置の場合において、初期暖機時において断熱材に奪われる熱量を低下することができる。
The angle (the above θ 0 ) with respect to the longitudinal direction of the tubular structure made of metal in the first direction and the second direction of the strip-shaped mat constituting the holding sealing material may be 45 °. Further, the same angle (the above θ 0 ) may be less than 45 ° or may exceed 45 °.
FIG. 5 shows an image of the heat transfer state when the woven fabric structure of one embodiment of the present invention is mounted around a tubular structure made of metal. The heat generated by the exhaust gas passing through the tubular structure 51 is transferred from the tubular structure 51 through the woven fabric structure 52 of the heat insulating material and is radiated. As shown in FIG. 5, the woven structure 52 has a small contact area with the tubular structure 51, and there are few contact points from which heat escapes, and the distance from the intersection of the strip mats to the intersection becomes long. It becomes difficult to transfer heat. Here, when the width d of the strip-shaped mat and the gap s between the strip-shaped mats shown in FIG. 2 are used, the area ratio of the contact point between the tubular structure 51 and the heat insulating material 52 is d 2 / (s + d) 2 . By increasing s, the area ratio of the contacts can be reduced. Therefore, for example, in the case where the tubular structure is an exhaust gas purification apparatus for automobiles, the amount of heat taken away by the heat insulating material during initial warm-up can be reduced.
断熱材の製造方法は、無機繊維を含む複数の短冊状マット材を作製する工程と、複数の短冊状マット材を第一の方向と第一の方向と交差する第二方向に織り合せる工程とを有する。この際、第一の短冊群中の一部の短冊状マット材と第二の短冊群中の一部の短冊状マット材が表面に交互に現れるように織り合わせる。短冊状マットの一部とは、短冊状マットが一つの場合と複数の編列した場合を含むことを意味しており、例えば、第一方向の短冊状マットと第二方向の短冊状マットが一つずつ表面に交互に現れるように織り合せてもよいし、複数の並列した短冊状マットが表面に交互に現れるように織り合せてもよい。また、短冊状マット材を作製する工程は、上述の方法により大面積のマット材を作製しを裁断することにより作製してもよいし、最初から短冊状のマットの形状に作製してもよい。 The method for manufacturing a heat insulating material includes a step of producing a plurality of strip-shaped mat members containing inorganic fibers, a step of weaving the plurality of strip-shaped mat members in a first direction and a second direction intersecting the first direction, Have At this time, weaving is performed so that a part of the strip-shaped mat members in the first strip group and a part of the strip-shaped mat members in the second strip group appear alternately on the surface. A part of the strip-shaped mat means that the strip-shaped mat includes a single strip-shaped mat and a plurality of knitted rows. For example, the strip-shaped mat in the first direction and the strip-shaped mat in the second direction are combined. They may be woven so that they appear alternately on the surface one by one, or may be woven so that a plurality of parallel strip-like mats appear alternately on the surface. The step of producing the strip-shaped mat material may be produced by producing a mat material having a large area by the above-described method and cutting the mat material, or may be produced from the beginning in the shape of a strip-like mat. .
断熱材は、金属からなる管状構造体の外側の一部または全面に配設することができる。
金属からなる管状構造体としては、例えば、自動車の排ガスパイプや排ガス浄化処理材を収容した排ガス浄化装置等がある。
図４には、図４（ａ）に示される自動車の排ガスパイプの金属からなる管状構造体４１に、図４（ｂ）に示されるように筒状の織物構造体からなる断熱材４２を被せた後、図４（ｃ）に示されるように、長手方向に引っ張ることにより自動車用排ガスパイプに簡易に密着して装着した例を示している。

FIG.6 (b) is the sectional view on the AA line of the exhaust gas purification apparatus shown by Fig.6 (a). FIG. 6C schematically shows a process of mounting the heat insulating material according to the embodiment of the present invention on the exhaust gas treatment apparatus shown in FIG. As shown in FIG. 6 (b), the exhaust gas purifying apparatus includes an exhaust gas treatment body 61, a casing 62 that houses the exhaust gas treatment body 61, and a holding sealing material 63 that is disposed between the exhaust gas treatment body 61 and the casing 62. And a cone converter 64 provided on at least one of the front and rear sides of the casing 52.
保持シール材６３は、排ガス処理体６１の周りに巻きつけられており、保持シール材６３によって排ガス処理体６１がケーシング６２内に保持されている。ケーシング６２の端部には、必要に応じて、内燃機関から排出された排ガスを導入する導入管と排ガス処理体を６１通過した排ガスが外部に排出される排出管（図示しない）とが接続される。
排ガス処理体６１は、通常、主として多孔質セラミックからなり、その形状は略円筒状である。また、排ガス処理体６１は、隔壁を隔てて長手方向に多数の貫通孔は併設されたはにかむ構造体とされている。排ガス処理体６１では、ハニカム構造体の隔壁に排ガス中に含まれるＣＯ、ＨＣ、ＮＯｘ等の有害なガス成分を浄化するための触媒が担持されている。触媒としては、白金などが使用される。
The holding seal material 63 is wound around the exhaust gas treatment body 61, and the exhaust gas treatment body 61 is held in the casing 62 by the holding seal material 63. An end of the casing 62 is connected to an introduction pipe for introducing exhaust gas discharged from the internal combustion engine and a discharge pipe (not shown) from which exhaust gas that has passed through the exhaust gas treatment body 61 is discharged to the outside as necessary. The
The exhaust gas treating body 61 is usually mainly made of porous ceramic, and has a substantially cylindrical shape. Further, the exhaust gas treating body 61 is a structure that has a large number of through holes provided in the longitudinal direction with a partition wall therebetween. In the exhaust gas treatment body 61, a catalyst for purifying harmful gas components such as CO, HC, NOx contained in the exhaust gas is supported on the partition walls of the honeycomb structure. As the catalyst, platinum or the like is used.
排ガス浄化装置を構成するケーシング６２は、通常、ステンレス等の金属からなり、その形状は略円筒である。ケーシング６２にはセンサーを貫通するための孔（図示しない）が設けられていてもよい。ケーシング６２の内径は排ガス処理体６１の端面の直径と、排ガス処理体に巻きつけられた状態の保持シール材の厚さとを合わせた長さより若干短くなっている。なお、ケーシングの長さは、排ガス処理体の長手方向における長さより若干長くてもよいし、排ガス処理体の長手方向における長さと略同一であってもよい。 The casing 62 constituting the exhaust gas purifying apparatus is usually made of a metal such as stainless steel and has a substantially cylindrical shape. The casing 62 may be provided with a hole (not shown) for penetrating the sensor. The inner diameter of the casing 62 is slightly shorter than the combined length of the diameter of the end face of the exhaust gas treatment body 61 and the thickness of the holding sealing material wound around the exhaust gas treatment body. The length of the casing may be slightly longer than the length in the longitudinal direction of the exhaust gas treatment body, or may be substantially the same as the length in the longitudinal direction of the exhaust gas treatment body.
排ガス浄化装置は、図６（ｃ）に示されるように筒状に織りあわされた織物構造体からなる断熱材６５内に挿入される。その後、織物構造体６５を排ガス浄化装置の軸方向に伸長することによって排ガス浄化装置に装着される。断熱材の外側の少なくとも一部に耐熱テープが配設されていてもよい。耐熱テープは、ガラスクロス、アルミまたはアルミガラスクロス等から選ばれる基材にシリコーン系粘着材等の粘着剤を塗布して構成することができる。また、断熱材の外側の少なくとも一部にカバーが配設されていてもよい。カバーはステンレス板、アルミメッキ鋼板または合成樹脂板等から構成されることができ、断熱材への風当たりを防止する機能を果たす。 The exhaust gas purification apparatus is inserted into a heat insulating material 65 made of a woven fabric structure woven in a cylindrical shape as shown in FIG. Thereafter, the fabric structure 65 is attached to the exhaust gas purification device by extending in the axial direction of the exhaust gas purification device.

まず、無機繊維を含む複数の短冊状マット材を作製する。短冊状マット材を作製するには、上述の方法により大面積のマット材を作製してこれを裁断することにより作製してもよいし、最初から短冊状のマットの形状に作製してもよい。
次に、複数の短冊状マット材を第一の方向と第一の方向と交差する第二方向に織り合せて、第一の短冊群中の一部の短冊状マット材と第二の短冊群中の一部の短冊状マット材が表面に交互に現れる筒状の織物構造体からなる断熱材を作製する。この際、第一の短冊群中の一部の短冊状マット材と第二の短冊群中の一部の短冊状マット材が表面に交互に現れるように織り合わせる。短冊状マットの一部とは、短冊状マットが一つの場合と複数の編列した場合を含むことを意味しており、例えば、第一方向の短冊状マットと第二方向の短冊状マットが一つずつ表面に交互に現れるように織り合せてもよいし、複数の並列した短冊状マットが表面に交互に現れるように織り合せてもよい。
次いで、例えば、図４（ｂ）に示されるように、金属からなる管状構造体４１に断熱材４２を被せた後、図４（ｃ）に示されるように断熱材４２を金属からなる管状構造体４１の長手方向に引張り、断熱材４２を管状構造体４１に密着させる。これにより断熱材を金属からなる管状構造体に簡易に固定することができる。
First, a plurality of strip-like mat members containing inorganic fibers are produced. In order to produce a strip-shaped mat material, it may be produced by producing a mat material having a large area by the above-described method and cutting the mat material, or may be produced in the shape of a strip-like mat from the beginning. .
Next, a plurality of strip-shaped mat members are woven in a first direction and a second direction intersecting the first direction, and a part of the strip-shaped mat members in the first strip group and the second strip group A heat insulating material made of a tubular woven fabric structure in which some of the strip-shaped mat members appear alternately on the surface is prepared. At this time, weaving is performed so that a part of the strip-shaped mat members in the first strip group and a part of the strip-shaped mat members in the second strip group appear alternately on the surface. A part of the strip-shaped mat means that the strip-shaped mat includes a single strip-shaped mat and a plurality of knitted rows. For example, the strip-shaped mat in the first direction and the strip-shaped mat in the second direction are combined. They may be woven so that they appear alternately on the surface one by one, or may be woven so that a plurality of parallel strip-like mats appear alternately on the surface.
Next, for example, as shown in FIG. 4 (b), the tubular structure 41 made of metal is covered with a heat insulating material 42, and then the heat insulating material 42 is made of a tubular structure made of metal as shown in FIG. 4 (c). Pulling in the longitudinal direction of the body 41, the heat insulating material 42 is brought into close contact with the tubular structure 41. Thereby, a heat insulating material can be simply fixed to the tubular structure which consists of metals.
以下実施例に基づいて本発明の実施形態を詳細に説明する。
アルミナ−シリカ組成を有するアルミナ繊維性の素地マットとして、組成比がＡｌ２Ｏ３：ＳｉＯ２＝７２：２８である素地マットを用意した。この素地マットに対し、ニードリング処理を施すことで、嵩密度が０．１５ｇ／ｃｍ３であり、坪量が４３０ｇ／ｃｍ２であるニードル処理マットを作製した。次に、ニードル処理マットを全長９００ｍｍ、幅２０ｍｍに裁断し、短冊状マットを得た。
Hereinafter, embodiments of the present invention will be described in detail based on examples.
A substrate mat having a composition ratio of Al 2 O 3 : SiO 2 = 72: 28 was prepared as an alumina fiber substrate having an alumina-silica composition. This needle mat was subjected to a needling treatment to produce a needle-treated mat having a bulk density of 0.15 g / cm 3 and a basis weight of 430 g / cm 2 . Next, the needle processing mat was cut into a total length of 900 mm and a width of 20 mm to obtain a strip-shaped mat.
実施例１では、短冊状マットの隙間を５ｍｍとして織り込み、直径１３０ｍｍ、長さ２８０ｍｍの筒状構造となる織物構造体を得た。実施例２〜５では、同様の短冊状マットを使用して、短冊状マット間の隙間をそれぞれ１０ｍｍ、２０ｍｍ、５０ｍｍ、６０ｍｍとして、直径１３０ｍｍ、長さ２８０ｍｍの筒状構造となる織物構造体を得た。実施例６及び７では、実施例１で得られた織物構造体をそれぞれ２個、３個積層して断熱材として使用した。実施例８では、短冊状マットの隙間を５ｍｍとして、平板状（幅４１０ｍｍ×長さ２８０ｍｍ）の構造体を得た。図７（ａ）には、実施例２により形成した筒状構造体の写真を示した。この筒状構造体は、梱包時または運搬時には図７（ｂ）のように平板状の形にすることができるため、積載性が良好となる。 In Example 1, a woven structure having a cylindrical structure with a diameter of 130 mm and a length of 280 mm was obtained by weaving the strip-shaped mat with a gap of 5 mm. In Examples 2-5, the same strip-shaped mat was used, and the woven fabric structure having a cylindrical structure with a diameter of 130 mm and a length of 280 mm, with the gaps between the strip-shaped mats being 10 mm, 20 mm, 50 mm, and 60 mm, respectively. Obtained. In Examples 6 and 7, two and three woven structures obtained in Example 1 were laminated and used as a heat insulating material. In Example 8, the gap between the strip-like mats was set to 5 mm, and a flat plate-like (width 410 mm × length 280 mm) structure was obtained. FIG. 7A shows a photograph of the cylindrical structure formed in Example 2. Since this cylindrical structure can be formed into a flat plate shape as shown in FIG. 7B at the time of packing or transportation, the loadability is improved.
比較例１では、ブランケット（厚さ６ｍｍ）を長方形（長さ４０５ｍｍ×幅１８７ｍｍ）と扇形（コーン部に使用）に裁断したものを使用した。また、比較例２では、アルミナ繊維スラリーを図７に示される形状の排気管に沿った形状の脱水成形型に供給して同配管の形状に合う２分割構造の３次元成形体を作製した。
図８に示される円筒部およびコーン部を有する排気管内に直径１０１．６ｍｍ、長さ１２７ｍｍの形状のコーディエライト製三元触媒からなる排ガス処理体を設置した。次に、実施例１〜８および比較例１および２の断熱材を排気管の外周に装着して、以下の評価指標により、（１）組み付け時の搭載性、（２）保温性、（３）梱包時の積載性を評価した。評価結果を表１に示した。表１において、それぞれの評価指標に基づいて、◎は非常に評価が高い、○は評価が高い、△は普通、×は評価が低い、ことを示している。
In Comparative Example 1, a blanket (thickness 6 mm) cut into a rectangle (length 405 mm × width 187 mm) and a fan shape (used for the cone portion) was used. In Comparative Example 2, the alumina fiber slurry was supplied to a dehydration mold having a shape along the exhaust pipe having the shape shown in FIG. 7 to produce a two-dimensional three-dimensional molded body matching the shape of the pipe.
An exhaust gas treating body made of cordierite three-way catalyst having a diameter of 101.6 mm and a length of 127 mm was installed in an exhaust pipe having a cylindrical portion and a cone portion shown in FIG. Next, the heat insulating materials of Examples 1 to 8 and Comparative Examples 1 and 2 are attached to the outer periphery of the exhaust pipe, and according to the following evaluation indices, (1) mountability during assembly, (2) heat retention, ) The loadability at the time of packing was evaluated. The evaluation results are shown in Table 1. In Table 1, based on each evaluation index, ◎ indicates that the evaluation is very high, ○ indicates that the evaluation is high, Δ indicates that the evaluation is normal, and × indicates that the evaluation is low.
（１）組み付け時の搭載性
排気管に組み付ける際の搭載性を装着時間として評価した。断熱材を固定するためのホースクランプを用いて、断熱材を直接固定した。装着開始から排気管に装着、固定されるまでに要した時間を測定し、搭載性の評価指標とした。装着時間が１５秒未満を◎、１５秒以上２０秒未満を○、２０秒以上３０秒未満を△、３０秒以上×とした。
(1) Mountability when assembled The mountability when assembled to the exhaust pipe was evaluated as the installation time. The heat insulating material was directly fixed using a hose clamp for fixing the heat insulating material. The time required from mounting start to mounting and fixing to the exhaust pipe was measured and used as an evaluation index for mounting ability. A wearing time of less than 15 seconds was evaluated as ◎, 15 seconds or more but less than 20 seconds as ◯, 20 seconds or more but less than 30 seconds as Δ, and 30 seconds or more as x.
（２）保温性
組みたてた排気管に、所定温度６００℃のガスを流入し、排気管から排出されるガスの温度計測し、保温性の評価指標とした。計測された温度が５９５℃以上を◎、５８９℃以上５９５℃未満を○、５８０℃以上５８９℃未満を△、５８０℃未満を×とした。
（３）梱包時の積載性
実施例１〜８の織物構造体の断熱材、比較例１のブランケット、比較例２の３次元成形体について、図８に示される排気管に使用される分量を断熱材１個として、幅３００ｍｍ×長さ４２０ｍｍ×深さ１８０ｍｍの箱の中に積載できる断熱材の個数により積載性の評価指標とした。１４個以上を◎、１１〜１３個を○、８〜１０個を△、７個以下を×とした。
(2) Thermal insulation The gas at a predetermined temperature of 600 ° C. flows into the assembled exhaust pipe, the temperature of the gas discharged from the exhaust pipe is measured, and used as an evaluation index for thermal insulation. The measured temperature is 595 ° C. or higher, ◎ is 589 ° C. or higher and lower than 595 ° C., 580 ° C. or higher and lower than 589 ° C. is Δ, and lower than 580 ° C. is X.
(3) Loadability at the time of packing About the heat insulating material of the textile structure of Examples 1-8, the blanket of Comparative Example 1, and the three-dimensional molded body of Comparative Example 2, the amount used for the exhaust pipe shown in FIG. As one heat insulating material, the evaluation index of loadability was used by the number of heat insulating materials that can be loaded in a box of width 300 mm × length 420 mm × depth 180 mm. 14 or more were evaluated as ◎, 11-13 as ◯, 8-10 as Δ, and 7 or less as ×.
表１に示されるように、実施例１〜４、６及び７は、搭載性、保温性、梱包時の積載性のいずれの評価も高く、実施例５では保温性の評価が普通であったが、搭載性と積載性の評価は高く、実施例８では搭載性の評価が普通であったが、保温性の評価は高く、積載性の評価は非常に高かった。
これに対して、比較例１では特に扇型部の搭載性が良くないため搭載性の評価が低く、また、比較例２では積載性の評価が低かった。
As shown in Table 1, Examples 1-4, 6 and 7 all had high evaluations of mountability, heat retention, and loadability at the time of packing, and in Example 5, evaluation of heat retention was normal. However, the evaluation of mountability and loadability was high. In Example 8, the evaluation of mountability was normal, but the evaluation of heat retention was high, and the evaluation of loadability was very high.
On the other hand, in Comparative Example 1, the mountability of the fan-shaped portion was not particularly good, so the evaluation of the mountability was low, and in Comparative Example 2, the evaluation of the loadability was low.
