Description
【０００１】[0001]
本考案は、室内暖房機の熱排気パイプや自動車のエンジン周り等において、こ れらの熱発生体に接触しやすい壁や電線等の外部の素材、あるいは人体を高熱か ら保護する断熱保護シートに関するものである。 The present invention is an insulating protective sheet that protects the external materials such as walls and electric wires that easily come into contact with these heat generators around the heat exhaust pipes of indoor heaters and the engine of automobiles, or the human body from high heat. It is about.
【０００２】[0002]
室内暖房機の熱排気パイプを室内外に配置する場合、接触する壁及び人体を高 熱から保護するために、アスベストクロス、ガラスクロス及び全芳香族ポリアミ ド繊維からなるフェルトが使われてきた。 When arranging heat exhaust pipes for indoor heaters indoors and outdoors, asbestos cloth, glass cloth, and felt made of wholly aromatic polyamid fiber have been used to protect contact walls and human body from high heat.
【０００３】 しかしながら、アスベストを素材としたものは耐熱性はあるが、人体に有害な 微細繊維が含まれているという欠点があり、ガラスクロスは比較的安価な難燃材 ではあるが、耐屈曲性が悪く、皮膚に触れると刺激があるという欠点がある。However, although the material made of asbestos has heat resistance, it has a drawback that it contains fine fibers harmful to the human body. Therefore, although glass cloth is a relatively inexpensive flame retardant material, it does not bend easily. It has the disadvantage that it is not good and that it is irritating to the skin.
【０００４】 全芳香族ポリアミド繊維からなるフェルトは軽くて難熱性に優れ、耐熱性もか なり良好であるが、このフェルトのみでは熱の反射が少なく、壁及び人体を高熱 から保護することができない。The felt made of wholly aromatic polyamide fiber is light and excellent in heat resistance and has excellent heat resistance. However, this felt alone does not reflect much heat and cannot protect the wall and human body from high heat. .
【０００５】 また、自動車のエンジン周りに用いられる内燃機関用断熱保護材として、実開 昭63-115538 号公報には、芳香族ポリアミド繊維からなるフェルト層に、ガラス 織布付きアルミ箔を、ガラス織布側をフェルト層に貼り合わせて一体化させ、さ らにフェルト層中に耐熱性と難燃性を持つ全芳香族ポリアミド繊維等の織布を基 布として有する断熱保護材が開示されている。Further, as a heat insulating protective material for an internal combustion engine used around the engine of an automobile, Japanese Utility Model Laid-Open No. 63-115538 discloses a felt layer made of an aromatic polyamide fiber, an aluminum foil with a glass woven cloth, and a glass foil. A heat insulation protective material is disclosed in which the woven fabric side is attached to the felt layer to be integrated, and the woven fabric such as wholly aromatic polyamide fiber having heat resistance and flame resistance is used as the base fabric in the felt layer. There is.
【０００６】 この断熱保護材は、アルミ箔を貼っているので熱反射性、冷却を早める放熱性 には優れるが、最外層のアルミ箔とガラス織布が一体であるため、外部から衝撃 を受けると衝撃が直接ガラス織布に伝わる。このため、耐屈曲性の悪いガラス織 布は破損し、折れやすく、十分な引張強度を保つことができない。 この欠点を補うため、フェルト層中に耐熱性と難燃性を持つ織布を基布として 挿入することで補強しているが、その分製造工程が複雑になりコストがかかると いう問題がある。[0006] This heat insulating protective material is excellent in heat reflectivity and heat radiating property for accelerating cooling because it is laminated with aluminum foil, but since the outermost layer aluminum foil and glass woven fabric are integrated, they are subject to external impact. And the shock is directly transmitted to the glass woven fabric. For this reason, the glass woven cloth having poor bending resistance is easily broken and easily broken, and sufficient tensile strength cannot be maintained. In order to compensate for this drawback, a woven fabric having heat resistance and flame resistance is inserted as a base fabric in the felt layer for reinforcement, but there is a problem that the manufacturing process becomes complicated and costly. .
【０００７】[0007]
本考案は、上述した問題点を解決し、耐熱性はもとより熱反射性、冷却を早め る放熱性に優れ、かつ十分な強度を持った断熱保護シートを低コストで提供する ことを技術的な課題とするものである。 The present invention solves the above-mentioned problems, and it is technically possible to provide a heat-insulating protective sheet with excellent strength as well as heat reflectivity and heat dissipation that accelerates cooling at low cost. This is an issue.
【０００８】[0008]
本考案者は、上記の課題を解決するために鋭意検討した結果、本考案に到達し た。 すなわち、本考案は、全芳香族ポリアミド繊維又は全芳香族ポリアミド繊維と 他の耐熱、難燃性を有する繊維からなるフェルト中にガラス繊維の布帛を基布と して有し、かつ前記フェルトの片面にアルミ箔を貼り合わせたことを特徴とする 断熱保護シートを要旨とするものである。 The present inventor has arrived at the present invention as a result of extensive studies to solve the above problems. That is, the present invention has a glass fiber cloth as a base fabric in a felt composed of wholly aromatic polyamide fibers or wholly aromatic polyamide fibers and other heat-resistant and flame-retardant fibers, and The main point is a heat-insulating protective sheet, which is characterized in that aluminum foil is attached to one surface.
【０００９】 以下、本考案を図面により詳細に説明する。 図１は、本考案の断熱保護シートの一実施態様を示す一部切欠斜視図である。 本考案の断熱保護シートは、まず、全芳香族ポリアミド繊維又は全芳香族ポ
リ アミド繊維に他の耐熱、難燃性を有する繊維を混ぜたウエブを上下に重ね、その 間にガラス繊維よりなる布帛の基布１を挿入してニードリングしてフェルト２と し、このフェルト２の片面にアルミ箔３を貼り合わせたものである。Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an embodiment of the heat insulating protective sheet of the present invention. The heat-insulating protective sheet of the present invention comprises firstly stacking a web of fully aromatic polyamide fibers or wholly aromatic polyamide fibers mixed with other heat-resistant and flame-retardant fibers on top of each other, and between them a glass fiber fabric. The base cloth 1 is inserted and needling is performed to form a felt 2, and an aluminum foil 3 is attached to one side of the felt 2.
【００１０】 本考案に用いる全芳香族ポリアミド繊維としては、パラ系アラミド繊維、メタ 系アラミド繊維の何れでもよいが、好ましくはメタフェニレンジアミンとイソフ タル酸クロライドから合成されるメタ系アラミド繊維、例えばアピエール（ユニ チカ製）等であり、繊度0.5 ｄ〜10ｄの繊維を用いるのが好ましい。The wholly aromatic polyamide fiber used in the present invention may be either a para-aramid fiber or a meta-aramid fiber, but preferably a meta-aramid fiber synthesized from metaphenylenediamine and isophthalic acid chloride, for example, Apierre (made by Unitika) and the like, and it is preferable to use fibers having a fineness of 0.5 d to 10 d.
【００１１】 全芳香族ポリアミド繊維と混合することのできる他繊維としては、炭素繊維、 フェノール繊維等、耐熱性と難燃性を有するものであれば特に限定されるもので はないが、他の繊維の混合割合が重量％で50％以下となるように全芳香族ポリア ミド繊維と混合するのが好ましい。The other fiber that can be mixed with the wholly aromatic polyamide fiber is not particularly limited as long as it has heat resistance and flame retardancy, such as carbon fiber and phenol fiber, but other It is preferable to mix with the wholly aromatic polyamide fibers so that the mixing ratio of the fibers is 50% or less by weight.
【００１２】 ガラス繊維の基布１は、11tex 〜270texのガラスフィラメントヤーンを経緯に 用いた目付け50ｇ／ｍ2 〜500 ｇ／ｍ2 の織物を用いるのが好ましい。 ガラス繊維は耐熱性、寸法安定性があり、引張強度が強いため基布１として用 いると、フェルト２は寸法安定性が向上し、かつ耐熱性及び強度のある布帛とな る。 このように、ガラス繊維の基布１をフェルト２の中に挿入することによって、 ガラス繊維が皮膚に触れたときに感じる特有の刺激を回避することができる。As the glass fiber base fabric 1, it is preferable to use a fabric having a basis weight of 50 g / m 2 to 500 g / m 2 using a glass filament yarn of 11 tex to 270 tex as a background. Since the glass fiber has heat resistance and dimensional stability, and has a high tensile strength, when used as the base fabric 1, the felt 2 has improved dimensional stability, and also has heat resistance and strength. In this way, by inserting the glass fiber base cloth 1 into the felt 2, it is possible to avoid the peculiar irritation felt when the glass fiber touches the skin.
【００１３】 フェルト２の片面にアルミ箔３を貼り合わせるが、アルミ箔３を貼ることによ って輻射熱を反射し、熱の拡散放射を早めて温度を効果的に下げることができる 。 アルミ箔３自体は伸びを有しないため引張り時に亀裂が生じやすいが、本考案 の断熱保護シートはガラス繊維の基布１により寸法安定性が優れるため、アルミ 箔３に亀裂が生じ難い。 アルミ箔３の厚さは、特に限定されるものではないが、７〜70μとすることが 好ましい。 なお、用途によってはフェルト２の両面にアルミ箔３を貼り付けてもよい。Although the aluminum foil 3 is attached to one surface of the felt 2, the attachment of the aluminum foil 3 reflects radiant heat and accelerates diffused heat radiation to effectively lower the temperature. Since the aluminum foil 3 itself does not have elongation, cracks are likely to occur during pulling, but the heat insulating protective sheet of the present invention is excellent in dimensional stability due to the glass fiber base fabric 1, and therefore the aluminum foil 3 is less likely to crack. The thickness of the aluminum foil 3 is not particularly limited, but is preferably 7 to 70 μ. The aluminum foil 3 may be attached to both sides of the felt 2 depending on the application.
【００１４】[0014]
次に、本考案を実施例によって具体的に説明する。 実施例１ 基布として、135texのガラスフィラメントヤーンを経糸及び緯糸に用いて、織 密度が経25本／2.54cm、緯24本／2.54cmで目付け 268ｇ／ｍ2 の平織物を製織し た。 全芳香族ポリアミド繊維として、メタ系アラミド繊維であるアピエール繊維 ( ユニチカ製) ２ｄ×51mmのウエブ（目付け75ｇ／ｍ2 ）上にガラス繊維の基布を 載置し、この上に前記と同じウエブを積層してニードルパンチし、目付け418 ｇ ／ｍ2 のフェルトとした。このフェルトの上面に厚さ40μのアルミ箔を接着剤で 貼り付けて断熱保護シートを作成した。Next, the present invention will be specifically described with reference to examples. Example 1 As a base fabric, a 135tex glass filament yarn was used for the warp and the weft, and a plain weave having a weave density of 25 warp / 2.54 cm, 24 weft / 2.54 cm and a basis weight of 268 g / m 2 was woven. As a wholly aromatic polyamide fiber, a glass fiber base cloth was placed on a 2d x 51mm web (unit weight 75g / m 2 ) of Apierre fiber (Unitika), which is a meta-aramid fiber, and the same web as above was placed on it. Were laminated and needle punched to obtain a felt having a basis weight of 418 g / m 2 . A 40μ thick aluminum foil was attached to the upper surface of this felt with an adhesive to form a heat insulating protective sheet.
【００１５】 得られた断熱保護シートを室内暖房機の熱排気パイプや自動車のエンジン周り 等に用いたところ、強度に優れ、耐熱性はもとより、熱反射性、冷却を早める放 熱性に優れ、皮膚への刺激もない良好なシートであった。When the obtained heat-insulating protective sheet was used around a heat exhaust pipe of an indoor heater or around an engine of an automobile, it was excellent in strength and heat resistance, as well as heat reflectivity and heat release to accelerate cooling, It was a good sheet with no irritation.
【００１６】[0016]
