発明の背景
１．発明の分野
この発明は、概して断熱材料に関し、より具体的には、少なくとも部分的にバサルト連続フィラメントから構成された断熱材料および管状スリーブに関する。 BACKGROUND OF THE INVENTION The present invention relates generally to thermal insulation materials, and more specifically to thermal insulation materials and tubular sleeves that are at least partially constructed from basalt continuous filaments.

２．関連技術
エンジン室内または排気マニホルドなどの熱源の近くに配置された自動車、航空、鉄道、および船舶用の構成部品は、過酷な熱環境に晒されることがある。さらに、所望されない熱伝達が、エンジン、排気システム、および／またはトランスミッションなどの熱源と、自動車、航空機、列車または船舶の客室との間で起こることもある。石油およびガス探鉱および掘削工具も、熱ならびに火花および火に晒されることからの防護を必要とする。断熱材料を用いて断熱パネルまたはスリーブを形成し、熱源から他の近傍の構成部品への熱伝達を減少させることは、当該技術分野において公知である。断熱材料は、その用途に適していなければならず、適性を保証するために、厳しい条件下で試験にかけられる。たとえば、温度の偏りが極端に大きく、構成部品が温度の影響を異常に受けやすい航空宇宙産業においては、断熱材料は、構成部品を、特に過酷な環境および条件から防護可能でなければならない。こうした過酷な環境は、裸火に晒されることを含む場合もあるので、もしこの断熱材料が耐火性であれば、それも有益である。 2. Related Art Components for automobiles, aviation, railroads, and ships located near heat sources such as engine compartments or exhaust manifolds may be exposed to harsh thermal environments. Furthermore, undesired heat transfer may occur between a heat source, such as an engine, exhaust system, and / or transmission, and a passenger cabin of an automobile, aircraft, train, or ship. Oil and gas exploration and drilling tools also require protection from heat and exposure to sparks and fire. It is known in the art to form a thermal insulation panel or sleeve using a thermal insulation material to reduce heat transfer from a heat source to other nearby components. The thermal insulation material must be suitable for its application and is tested under harsh conditions to ensure suitability. For example, in the aerospace industry, where the temperature bias is extremely large and the components are unusually susceptible to temperature, the thermal insulation material must be able to protect the components from particularly harsh environments and conditions. Since these harsh environments can include exposure to open flames, it is also beneficial if the insulation material is fire resistant.

先行技術には、このようなパネルの断熱層として用いられる材料が豊富にある。たとえば、このようなパネルまたはスリーブの断熱材料として作用するさまざまな繊維材料およびこの繊維材料の組成を用いることが公知である。ガラス繊維、シリカ、バサルト、およびセラミック繊維などの鉱物繊維は、当該技術分野において断熱材料として全て公知である。これらの材料はそれぞれ、たとえば、異なる物理的および機械的特性、動作温度限界、耐熱性、および耐薬品性などの、それぞれの材料を特定の用途に対してより適したものにする異なる特性を有する。   The prior art is abundant in the materials used as thermal insulation layers for such panels. For example, it is known to use various fiber materials and compositions of such fiber materials that act as thermal insulation materials for such panels or sleeves. Mineral fibers such as glass fibers, silica, basalt, and ceramic fibers are all known as thermal insulation materials in the art. Each of these materials has different properties that make each material more suitable for a particular application, such as, for example, different physical and mechanical properties, operating temperature limits, heat resistance, and chemical resistance. .

現代のエンジンは、数年前のエンジンよりも高い温度で動作し、よって、現代のエンジンのための断熱材料は、少し前に用いられた断熱材料と比較してさえ、より要求の厳しい条件下で機能することが求められる。現代の用途の中には、一部の先行技術材料によっては実現できない極端な温度における構成部品の防護を必要とする用途もある。よって、自動車、航空機、列車、および船舶製造業者は、このような用途に対して十分な機能を提供する、より新しく、より強い材料を使用することが求められる。さらに、温度の影響を受けやすい構成部品（たとえば、センサ）を発熱体または熱導体の至近距離で用いることが増加してきたことにより、極端な熱に対する防護を要求する、要求の厳しい新しい用途が多数登場してきている。   Modern engines operate at higher temperatures than engines a few years ago, so the insulation material for modern engines is even more demanding under conditions even compared to the insulation material used a while ago It is required to function in. Some modern applications require protection of components at extreme temperatures that cannot be achieved with some prior art materials. Thus, automobile, aircraft, train and ship manufacturers are required to use newer and stronger materials that provide sufficient functionality for such applications. In addition, the increasing use of temperature-sensitive components (eg, sensors) in close proximity to heating elements or heat conductors has led to many demanding new applications that require protection against extreme heat. Has appeared.

This material is easy to handle and can be widely used throughout the vehicle, for example, because it can be of various shapes and formed into an elastic structure. Furthermore, this material is generally economical in design, manufacture and use.

現在好ましい実施例の詳細な説明
図面をより詳細に参照して、図１は、この発明の１つの現在好ましい実施例に従う複数のバサルト連続フィラメント１２から構成される繊維断熱材料１０を示す。バサルト連続フィラメント１２は耐火性であり、極度に高い温度（たとえば、７６０℃）および極度に低い温度（たとえば、−２６０℃）に対する熱的な防護も提供することができる。この発明に従う織り合わされたバサルト連続フィラメント１２で製造された布地シート、パネル、スリーブ、または他の構造は、今日使用される多くの断熱および耐火材料よりも優れており、今日使用される多くの断熱および耐火材料を補完または代替するために用いてもよい。非限定的例として、スリーブ１４、１５、および１６が図２から図４にそれぞれ示され、スリーブ１４、１５、および１６は、少なくとも部分的にバサルト連続フィラメント１２から製造され、ゆえに、極端に高い熱に晒される配管（５００℃から７６０℃の温度を有する排気管など）、または超低温管もしくはタンク（それぞれ−１９１℃および−１６１℃もの低温に達することがある液体窒素または圧縮天然ガスタンクなど）を断熱するためにたとえば用いてもよい。 Detailed Description of the Presently Preferred Embodiment Referring to the drawings in more detail, FIG. 1 shows a fiber insulation material 10 comprised of a plurality of basalt continuous filaments 12 according to one currently preferred embodiment of the present invention. The basalt continuous filament 12 is fire resistant and can also provide thermal protection against extremely high temperatures (eg, 760 ° C.) and extremely low temperatures (eg, −260 ° C.). Fabric sheets, panels, sleeves, or other structures made with interwoven basalt continuous filaments 12 according to the present invention are superior to many insulation and refractory materials used today, and many insulations used today. And may be used to supplement or replace refractory materials. As a non-limiting example, sleeves 14, 15, and 16 are shown in FIGS. 2-4, respectively, and sleeves 14, 15, and 16 are manufactured at least partially from basalt continuous filament 12, and are therefore extremely high Piping exposed to heat (such as an exhaust pipe having a temperature of 500 ° C. to 760 ° C.), or a cryogenic pipe or tank (such as a liquid nitrogen or compressed natural gas tank that may reach temperatures as low as −191 ° C. and −161 ° C., respectively) For example, it may be used to insulate.

この発明の１つの局面に従い、複数のバサルト連続フィラメント１２が配置され、ヤーンまたはヤーン状のストランド１８を形成する。１つの現在好ましい実施例においては、ヤーン状のストランド１８は、ストランド１８の体積を増大させ、ストランド１８の本体内に空洞部分を作るように、織地化される。バサルト連続フィラメントヤーン１８を織地化することにより、バサルト連続フィラメントヤーン１８によって、ヤーン重量を減少しながらの熱的防護の向上を実現することができ、吸音性の向上も実現することができる。１つの現在好ましい実施例において、ヤーン１８のストランドは、空気織地化（air-texturized）され、密度は約１８００ｔｅｘである。別の現在好ましい実施例においては、ヤーン１８のストランドは、空気織地化（air texturization）ではなく延伸織地化（draw texturization）される。このようであるので、ヤーン１８は、任意の適切な密度を持つ
ように織地化されることができる。概して、より細いヤーン１８は、より可撓性のある材料を作るために用いられ、より太いヤーン１８は、被覆の向上を実現するために用いられる。したがって、ヤーンの密度の選択と、使用されるバサルトフィラメントの選択とは、構成する材料の種類と、得られる材料の用途とに基づく。さらに別の現在好ましい実施例においては、ヤーン１８のストランドは、織地化される代わりに、撚り合わされる。この構造では、ヤーン１８の密度は約２６０ｔｅｘであり、１メートルあたり１２０回転撚り合わさるが、所望される用途に基づいて、任意のストランド密度および１メートルあたりの撚り数が用いられてもよい。断熱材料の耐摩耗性は、撚り合わせの程度が増加するにつれて増加することが明らかになっている。さらに別の現在好ましい実施例においては、ストランド１８は、まず織地化され、その後撚り合わされる。こういった織地化されたおよび/または撚り合わされたバサルト連続フィラメントヤーン１８の多くは、より詳しく以
下に説明されるように、単一構造の断熱材料を構成するために作られ、使用される。 In accordance with one aspect of the present invention, a plurality of basalt continuous filaments 12 are disposed to form a yarn or yarn-like strand 18. In one currently preferred embodiment, the yarn-like strands 18 are woven to increase the volume of the strands 18 and create a hollow portion within the body of the strands 18. By weaving the basalt continuous filament yarn 18, the basalt continuous filament yarn 18 can improve thermal protection while reducing the yarn weight, and can also improve sound absorption. In one currently preferred embodiment, the strands of yarn 18 are air-texturized and have a density of about 1800 tex. In another currently preferred embodiment, the strands of yarn 18 are drawn texturized rather than air texturized. As such, the yarn 18 can be woven to have any suitable density. Generally, the thinner yarn 18 is used to make a more flexible material and the thicker yarn 18 is used to achieve improved coating. Therefore, the choice of yarn density and the basalt filament used is based on the type of material to be constructed and the intended use of the resulting material. In yet another currently preferred embodiment, the strands of yarn 18 are twisted instead of woven. In this construction, the density of yarn 18 is about 260 tex and twists 120 revolutions per meter, although any strand density and number of twists per meter may be used based on the desired application. It has been shown that the wear resistance of a thermal insulation material increases as the degree of twisting increases. In yet another currently preferred embodiment, the strands 18 are first woven and then twisted. Many of these woven and / or twisted basalt continuous filament yarns 18 are made and used to construct a unitary insulating material, as will be described in more detail below.

ヤーン１８の数多くのバサルト連続フィラメントストランドを得た後、このストランド１８は断熱材料の所望の構造を作る構成に配置される。１つの実施例においては、ストランド１８は織られ、断熱材料１０またはスリーブ１４、１５、および１６を作るが、、ストランド１８を編み合わせるために、編成、織成、縫成、鉤針編み、刺繍縫い、および組成を含むがこれに限定されない任意の構造方法を用いることができる。用途によっては、上述の構造方法のうち１つ以上が好まれてもよい。たとえば、ある場合においては、より大きな被覆と軽い重量を得ることができるため、組まれ、織地化されたバサルト連続フィラメントスリーブが好まれることがある。   After obtaining a number of basalt continuous filament strands of yarn 18, this strand 18 is placed in a configuration that creates the desired structure of thermal insulation material. In one embodiment, the strands 18 are woven to create the thermal insulation material 10 or sleeves 14, 15, and 16, but to knit the strands 18, they are knitted, woven, sewn, crochet and embroidery stitched. And any structural method including, but not limited to, composition. Depending on the application, one or more of the above structural methods may be preferred. For example, in some cases, a basalt continuous filament sleeve that is assembled and textured may be preferred because it allows greater coverage and lighter weight.

さらに、断熱繊維材料１０は、繊維布地１０ならびにスリーブ１４、１５、および１６を含むがこれに限定されない任意の構成に形成されてもよく、スリーブ１４、１５、および１６は、連続した閉鎖周方向壁２０（図２）構造、またはスリーブ１５の長さ方向に沿って互いに好ましくは重なった長手方向縁部１７および長手方向縁部１９を有する開放壁２０（図３）構造を備えることができる。さらに、スリーブ１４、１５、および１６は１つ以上の断熱材料層を含んでもよい。非限定的な例として図４に示されるように、断熱スリーブ１６はスリーブ１６の２つの層２０および２２を形成するように自身の上に折り返された単層編成スリーブ、または複層スリーブを形成するために自身の上に前後に折り返された単層編成スリーブとして作られてもよい。さらに、スリーブ１４、１５および１６のうち任意のものは、図２において概ね２１に示されるように、天然のバサルトの色以外の色を所望する場合は、顔料を含む耐熱コーティングで被膜されてもよい。   Further, the insulating fiber material 10 may be formed in any configuration including, but not limited to, a fiber fabric 10 and sleeves 14, 15, and 16, wherein the sleeves 14, 15, and 16 are continuous closed circumferential directions. A wall 20 (FIG. 2) structure or an open wall 20 (FIG. 3) structure having a longitudinal edge 17 and a longitudinal edge 19 that preferably overlap one another along the length of the sleeve 15 can be provided. Further, the sleeves 14, 15, and 16 may include one or more layers of thermal insulation material. As shown in FIG. 4 as a non-limiting example, the insulating sleeve 16 forms a single layer knitted sleeve or a multi-layer sleeve folded over itself so as to form the two layers 20 and 22 of the sleeve 16. To do so, it may be made as a single layer knitted sleeve folded back and forth on itself. Further, any of the sleeves 14, 15 and 16 may be coated with a heat resistant coating containing a pigment if a color other than that of natural basalt is desired, as shown generally at 21 in FIG. Good.

この発明の別の局面に従い、バサルト連続フィラメントで構成される断熱層２０に加えて、たとえば、図１の概ね２３に示されるような層が、断熱材料１０またはスリーブ１４、１５、および１６上に存在してもよい。これらの追加的な層２３は、たとえば、シリコン樹脂、ゴム、アルミニウムまたは他の金属、エポキシ樹脂、炭素繊維、セラミックおよびプラスチックまたはこれらの合成物を含んでもよい。このようであるので、断熱スリーブ１４、１５、および１６は、断熱材料２０の外側表面に、たとえばシリコンゴム被膜を施される層２３を有し、織られたまたは組まれたバサルト連続フィラメント２０の断熱単層または複層を含むことができる。上述の材料層に加えて、他の種類の材料層が、上述の断熱材料１０およびスリーブ１４、１５、および１６を用いて、航空機のホースが炎に晒されたときに直ちに炎上しないよう保護するのに適した用途などで用いられてもよい。この用途においては、断熱材料１０および/またはスリーブ１４、１５、および１６を、図
３において概ね２５に示される発泡性防炎被膜（intumescent coating）で被膜すること
ができる。この発泡性防炎被膜２５は、断熱材料１０またはスリーブ１４、１５、および１６に接着することができ、織地化されたバサルト連続フィラメントスリーブ１４、１５、および１６に、さらなる断熱および耐火性をもたらす。発泡性防炎被膜２５は、スリーブ１４、１５、および１６の最も外側の表面にのみ施されてもよく、または所望されるならばすべての表面に施されてもよい。 In accordance with another aspect of the present invention, in addition to the thermal insulation layer 20 comprised of basalt continuous filaments, for example, a layer as shown generally at 23 in FIG. 1 is provided on the thermal insulation material 10 or sleeves 14, 15, and 16. May be present. These additional layers 23 may comprise, for example, silicon resin, rubber, aluminum or other metal, epoxy resin, carbon fiber, ceramic and plastic or composites thereof. As such, the insulating sleeves 14, 15, and 16 have a layer 23 that is coated, for example, with a silicone rubber coating, on the outer surface of the insulating material 20, and the woven or assembled basalt continuous filament 20. Insulating single layers or multiple layers can be included. In addition to the material layers described above, other types of material layers use the thermal insulation material 10 and sleeves 14, 15, and 16 described above to protect the aircraft hose from immediately burning when exposed to flame. It may be used for applications suitable for the above. In this application, the thermal insulation material 10 and / or the sleeves 14, 15, and 16 can be coated with a foamable intumescent coating, shown generally at 25 in FIG. This foamable flame barrier coating 25 can be adhered to the thermal insulation material 10 or the sleeves 14, 15, and 16 and provides further thermal insulation and fire resistance to the woven basalt continuous filament sleeves 14, 15, and 16. . The foamable flame barrier coating 25 may be applied only to the outermost surface of the sleeves 14, 15, and 16, or may be applied to all surfaces if desired.

上述の断熱および耐火材料１０ならびにスリーブ１４、１５、および１６は、数多くの用途に用いられてもよい。たとえば、バサルト連続フィラメントヤーン１８を含む、編まれた、織られた、または組まれたスリーブ１４、１５、および１６を、排気管を断熱するために使用し、この排気管が生み出す極度に高い熱が、車両内にある、温度の影響を受けやすい近くの構成部品に損傷を与えることを防止してもよい。スリーブ１４、１５、および１６の編まれた構造は、１つの好ましい構造であり、なぜならば、編まれた構造は、スリーブ１４、１５、および１６の単一の壁または複数の壁に径方向の伸張性をもたらすので、取り付けしやすいためである。上述のように、バサルト連続フィラメントヤーン１８は、織地化されても、または撚り合わされてもよく、織地化されたバージョンが、多くの用途において好ましい。   The above-described thermal insulation and refractory material 10 and sleeves 14, 15, and 16 may be used in numerous applications. For example, knitted, woven or braided sleeves 14, 15 and 16 containing basalt continuous filament yarn 18 are used to insulate the exhaust pipe, and the extremely high heat that this exhaust pipe produces. May prevent damage to nearby components in the vehicle that are sensitive to temperature. The knitted structure of the sleeves 14, 15, and 16 is one preferred structure because the knitted structure is radial to the single wall or multiple walls of the sleeves 14, 15, and 16. This is because it provides extensibility and is easy to install. As mentioned above, the basalt continuous filament yarn 18 may be woven or twisted, and a woven version is preferred in many applications.
