Description
本発明は膜構造の建築物に使用されるガラス繊維織物複合不燃シート材であって、好ましくは膜構造の建築物のテント倉庫建築物用の膜材料に好適なガラス繊維織物複合不燃シート材に関するものである。 The present invention relates to a glass fiber woven composite non-combustible sheet material used in a membrane structure, preferably a glass fiber woven composite non-combustible sheet material suitable for a membrane material for a tent warehouse building of the membrane structure. It is a thing.
膜構造の建築物に使用される膜材料の基布は、ガラス繊維織物やポリアミド系、ポリアラミド系、ポリエステル系、ポリビニルアルコール系又はオレフィン系樹脂の合成繊維の織物が使用されている。テント倉庫建築物は、主に工場敷地内に建設され、資材や原料、中間品や製品などを一時的に保管するための施設で、屋根部分、側壁部分とも膜材料で構成された建築物である。それ故、テント倉庫建築物に出入りするフォークリフトの衝突や積荷の接触によるテント倉庫建築物の穴開き破損が度々生じている。 As a base fabric of a membrane material used for a building having a membrane structure, a glass fiber woven fabric or a synthetic fiber woven fabric of polyamide type, polyaramid type, polyester type, polyvinyl alcohol type or olefin type resin is used. A tent warehouse building is a facility that is mainly constructed on the premises of a factory and temporarily stores materials, raw materials, intermediate products, and products.The roof and side walls are made of membrane material. is there. Therefore, the tent warehouse building is often pierced and damaged due to collision of forklift trucks entering and leaving the tent warehouse building and contact of cargo.
特に、基布にガラス繊維織物を使用した膜材料はガラス繊維糸が不燃性能に優れるという防災上の安全性を活かし、膜構造の建築物やテント倉庫建築物の膜材料に広く使われるようになってきている。 In particular, membrane materials that use glass fiber woven fabric as the base cloth are widely used as membrane materials for building structures and tent warehouse buildings, taking advantage of the safety of disaster prevention that glass fiber yarn has excellent non-combustible performance. It has become to.
ガラス繊維糸を経糸及び緯糸に用いたガラス繊維織物を基布としたシート材は、ガラス繊維糸が高い引張強さ持つため膜材料も高い引張強さを持つ。しかし、ガラス繊維糸は折り曲げに弱いため膜材料の引裂強さに劣る欠点があり、そのためフォークリフトや積荷の衝突で、テント倉庫建築物の破損が鍵裂き状に伝播して、その補修を大掛かりなものとしている。現在テント倉庫建築物の膜材料の基布のガラス繊維織物は、最低限の引裂強さを確保するため、経糸方向、緯糸方向の織り糸の番手が１３５ｔｅｘ以上の糸が用いられ、このような破損事故に対するガラス繊維織物による対応が行われているが、ガラス繊維糸は折り曲げに弱いという固定観念によりこれ以上何ら検討もなされていない。 A sheet material based on a glass fiber woven fabric using glass fiber threads as warp and weft has high tensile strength because the glass fiber threads have high tensile strength. However, since glass fiber yarn is weak in bending, it has a drawback of being inferior in tear strength of the membrane material.Therefore, a collision of a forklift or a load causes damage to the tent warehouse building to propagate in a key-splitting manner, which requires a large amount of repair work. I am supposed to. At present, the glass fiber woven fabric, which is the base material of the membrane material of the tent warehouse building, has a yarn count of 135 tex or more in the warp direction and the weft direction in order to ensure the minimum tear strength, and such damage is caused. Glass fiber fabrics have been used to deal with accidents, but no further consideration has been made due to the stereotype that glass fiber yarns are fragile.
基布のガラス繊維織物の織り糸の更に詳しくは、番手が６７．５ｔｅｘで２５ｍｍ当り１．０回のＺ撚りの単糸のガラス繊維糸を用い、これを２５ｍｍ当り４．０回のＺ撚りの追撚りを加えたものを２本撚り合わせ２５ｍｍ当り３．８回のＳ撚りの合撚糸の織り糸の番手１３５ｔｅｘを用いるのが殆どである。しかしこの場合、合撚糸を織り糸とするため、合撚工程が必要となり、合撚工程での織り糸への汚れ付着が、透光率の高い膜材料の場合は織り糸汚れが美観を損ねるという問題が生じ、近年のテント倉庫建築物は、日中、内部の照明の省エネルギーの観点より、透光率の高い膜材料が求められることが多いので大きな問題となってきている。また合撚という余分な１工程が必要で、経済合理性の観点でも好ましくはないが、前記記載の通りガラス繊維糸は折り曲げに弱いという固定観念によりこれ以上何ら検討もなされていない。 More specifically, the weaving yarn of the base glass fiber woven fabric is a single-ply glass fiber yarn having a count of 67.5 tex and having a Z twist of 1.0 times per 25 mm, and this has a Z twist of 4.0 times per 25 mm. In most cases, a yarn count of 135 tex, which is a weaving yarn of S-twisted 3.8 times per 25 mm, is used in which two additional twists are twisted. However, in this case, since the twisted and twisted yarn is used as the weaving yarn, there is a problem that the twisting and twisting process is required, and the stain adherence to the weaving yarn in the twisting and twisting process deteriorates the appearance of the yarn in the case of a film material having high light transmittance. In recent years, tent warehouse buildings have become a big problem because a film material having a high light transmittance is often required from the viewpoint of energy saving of internal lighting during the daytime. Further, it requires an extra step of twisting, which is not preferable from the viewpoint of economic rationality, but as described above, the glass fiber yarn has not been studied further due to the fixed idea that it is weak in bending.
本発明は膜構造の建築物に使用されるガラス繊維織物複合不燃シート材であって、特にガラス繊維糸が不燃性能に優れるという特徴を活かし、膜構造の建築物のテント倉庫建築物に用いる際に、フォークリフトや積荷がテント倉庫に接触しても、その損傷ダメージをより小さいものとする効果を有するような、高い引張強さと高い引裂強さを併せもち、かつ不燃性能も優れたガラス繊維織物複合不燃シート材を提供することを課題とする。 INDUSTRIAL APPLICABILITY The present invention is a glass fiber woven composite non-combustible sheet material used for a membrane structure, particularly when it is used for a tent warehouse building of a membrane structure by taking advantage of the feature that the glass fiber yarn has excellent non-combustibility performance. In addition, even if a forklift or load comes into contact with the tent warehouse, it has the effect of making damage damage smaller, and has high tensile strength and high tear strength, and it is also a glass fiber woven fabric with excellent non-combustibility performance. An object is to provide a composite noncombustible sheet material.

Phthalate ester-based plasticizers such as decyl phthalate and butylbenzyl phthalate, non-phthalate ester-based plasticizers such as 1,2-cyclohexanedicarboxylic acid dialkyl ester are used, and adipic acid is used as a polyester-based plasticizer. -Methyl-1,8-octanediol, 1,2-propanediol, 1,3-butanediol, 2-ethylhexanol, and products esterified with one or more glycols such as n-octanol are used. It is possible Further, as the trimellitic acid-based plasticizer, tri-2-ethylhexyl trimellilate, triisodecyl trimellilate, or the like can be used, and as the other plasticizer, a pyromellitic acid-based plasticizer such as 2-ethylhexylpyromellilate. A plasticizer or the like can also be used. Further, as the polymer having a plasticizing action, an ethylene-vinyl acetate copolymer and / or a polymer obtained by introducing carbon monoxide into an ethylene-acrylic acid ester copolymer can be used. Such polymers include Elvalloy 742 ™ manufactured by Mitsui DuPont Chemicals.
塩化ビニル系樹脂に対する可塑剤の添加量は、塩化ビニル系樹脂１００重量部に対して３０〜１６０重量部であることが好ましく、３５〜１２０重量部であることがより好ましい。可塑剤の添加量が３０重量部を下回ると、得られる塩化ビニル樹脂被覆層が過度に硬くなり、屈曲等の動きに追従できなくなり、亀裂が発生しやすくなることがある。また、可塑剤の添加量が１６０重量部を超えると、得られる塩化ビニル樹脂被覆層の樹脂強度の低下や、可塑剤が塩化ビニル樹脂被覆層の表面に移行して、表面に汚れが付着しやすくなるなどの問題を発生することがある。 The amount of the plasticizer added to the vinyl chloride resin is preferably 30 to 160 parts by weight, more preferably 35 to 120 parts by weight, based on 100 parts by weight of the vinyl chloride resin. When the amount of the plasticizer added is less than 30 parts by weight, the obtained vinyl chloride resin coating layer becomes excessively hard, cannot follow movements such as bending, and cracks are likely to occur. If the amount of the plasticizer added exceeds 160 parts by weight, the resin strength of the vinyl chloride resin coating layer obtained will be reduced, or the plasticizer will migrate to the surface of the vinyl chloride resin coating layer and stains will adhere to the surface. It may cause problems such as easier operation.
塩化ビニル系樹脂被覆層には無機系難燃剤が含まれており、無機系難燃剤の配合量は塩化ビニル系樹脂１００重量部に対し０．５〜１７０重量部であることが好ましく、１〜１３０重量部であることが更に好ましい。無機系難燃剤の配合量が０．５重量部未満の場合は、塩化ビニル樹脂被覆層の難燃性が不十分となり、また、１７０重量部を越える場合には、塩化ビニル樹脂被覆層の柔軟性及び樹脂強度が低下し、被膜の耐屈曲性の低下や、基布のガラス繊維織物と塩化ビニル樹脂被覆層との間の剥離強度の低下がある。 The vinyl chloride resin coating layer contains an inorganic flame retardant, and the compounding amount of the inorganic flame retardant is preferably 0.5 to 170 parts by weight with respect to 100 parts by weight of the vinyl chloride resin, 1 to More preferably, it is 130 parts by weight. When the content of the inorganic flame retardant is less than 0.5 part by weight, the flame retardancy of the vinyl chloride resin coating layer becomes insufficient, and when it exceeds 170 parts by weight, the flexibility of the vinyl chloride resin coating layer is low. Properties and resin strength are reduced, the flex resistance of the coating is reduced, and the peel strength between the glass fiber woven fabric of the base fabric and the vinyl chloride resin coating layer is reduced.
塩化ビニル系樹脂被覆層に使用される無機系難燃剤としてはアンチモン化合物、モリブデン化合物、ほう酸亜鉛、硫酸バリウム、水酸化アルミニウム、水酸化マグネシウム、ポリリン酸アンモン、赤リンなどを単独で或いは２種類以上の混合物として使用できる。これらの中で特に、無機系難燃剤として好ましいものは三酸化アンチモン、五酸化アンチモンなどのアンチモン化合物及びモリブデン化合物である。アンチモン化合物は、塩化ビニル系樹脂に高い難燃性を付与し、燃え広がりを防止する作用が強く、またモリブデン化合物は燃焼熱を低く抑え、発煙量を抑え有害燃焼ガスを低減する。モリブデン化合物としては、モリブデン酸カルシウム亜鉛、モリブデン酸カリウム、モリブデン酸ナトリウム、モリブデン酸炭酸カルシウム、モリブデン酸アンモン等が挙げられる。また、無機系難燃剤には、あらかじめシランカップリング処理を施し塩化ビニル系樹脂被覆層との密着性を高めておいても良い。また他の難燃剤、例えばブロム系防炎剤、リン酸エステル、含ハロゲンリン酸エステル、塩素化パラフィンなども適宜使用できる。ブロム系防炎剤としてはデカブロモジフェニルエーテル、ペンタブロモメチルベンゼン、ヘキサブロモベンゼンなどが使用できる。リン酸エステルとしてはトリフェニルホスフェート、トリクレジルホスフェート、クレジルジフェニルホスフェート等が使用できる。 As the inorganic flame retardant used in the vinyl chloride resin coating layer, antimony compound, molybdenum compound, zinc borate, barium sulfate, aluminum hydroxide, magnesium hydroxide, ammonium polyphosphate, red phosphorus, etc. may be used alone or in combination of two or more. Can be used as a mixture. Among these, particularly preferable as the inorganic flame retardant are antimony compounds such as antimony trioxide and antimony pentoxide, and molybdenum compounds. The antimony compound imparts high flame retardancy to the vinyl chloride resin and has a strong effect of preventing flaming, and the molybdenum compound suppresses combustion heat to a low level, suppresses smoke generation and reduces harmful combustion gas. Examples of the molybdenum compound include calcium zinc molybdate, potassium molybdate, sodium molybdate, calcium molybdate carbonate, and ammonium molybdate. Further, the inorganic flame retardant may be subjected to silane coupling treatment in advance to enhance the adhesiveness with the vinyl chloride resin coating layer. Further, other flame retardants such as bromine flame retardants, phosphoric acid esters, halogen-containing phosphoric acid esters, and chlorinated paraffins can be appropriately used. As the bromine flame retardant, decabromodiphenyl ether, pentabromomethylbenzene, hexabromobenzene and the like can be used. As the phosphoric acid ester, triphenyl phosphate, tricresyl phosphate, cresyl diphenyl phosphate and the like can be used.
塩化ビニル系樹脂被覆層に含まれる安定剤としては、カルシウム・亜鉛系、バリウム・亜鉛系、カドミウム・バリウム系、鉛系、有機錫ラウレート系、及び有機錫メルカプタイト系、及びエポキシ系などの安定剤を単独或いはその２種以上を混合して使用できる。 The stabilizer contained in the vinyl chloride resin coating layer includes calcium / zinc based, barium / zinc based, cadmium / barium based, lead based, organotin laurate based, organotin mercaptite based, and epoxy based stabilizers. Can be used alone or in admixture of two or more.
