建築膜材料用無機繊維織物及び建築膜材料Inorganic fiber fabrics for building membrane materials and building membrane materials
　本発明は、建築膜材料用無機繊維織物及び建築膜材料に関する。 The present invention relates to inorganic fiber fabrics for building membrane materials and building membrane materials.
　従来、建築物又は構築物用の膜材料（以下、建築膜材料という）として、ガラス繊維織物と、該ガラス繊維織物の表裏両面を被覆する被覆樹脂とを含む、不燃シートが知られている（例えば、特許文献１参照）。 Conventionally, as a film material for buildings or constructions (hereinafter referred to as a building film material), a noncombustible sheet containing a glass fiber fabric and a coating resin covering both the front and back sides of the glass fiber fabric is known (for example, , see Patent Document 1).
　ところが、前記従来の不燃シートは、発熱量の観点から不燃認定を受けることが可能であっても、高温で長時間加熱された場合に、該不燃シート中のガラス繊維織物に破損が生じる虞がある。このため、特に前記不燃シートを天井材として用いる場合、火災発生時に、前記ガラス繊維織物の破損により、該不燃シートが落下する虞があり、必ずしも十分な耐火性を備えているとは言えない。 However, even if the conventional noncombustible sheet can be certified as noncombustible from the viewpoint of the amount of heat generated, there is a risk that the glass fiber fabric in the noncombustible sheet will be damaged when heated at a high temperature for a long time. be. For this reason, especially when the noncombustible sheet is used as a ceiling material, there is a risk that the noncombustible sheet may fall due to breakage of the glass fiber fabric in the event of a fire, and it cannot necessarily be said to have sufficient fire resistance.
　一方、アルミナ繊維織物を含む耐火材料が知られている（例えば、特許文献２参照）。 On the other hand, refractory materials containing alumina fiber fabrics are known (see Patent Document 2, for example).

　しかしながら、前記アルミナ繊維織物は、ガラス繊維織物に比較して製織性に劣る上、該アルミナ繊維織物と、該アルミナ繊維織物の表裏両面を被覆する被覆樹脂とを含む、シート材は、建築膜材料として十分な強度を備えることができないという不都合がある。 However, the alumina fiber fabric is inferior to the glass fiber fabric in weaving properties, and the sheet material containing the alumina fiber fabric and the coating resin covering both the front and back surfaces of the alumina fiber fabric is a building membrane material.
