Description

本考案は、様々な用途に使用できる難燃性吸音仕上げ部材に関するものである。   The present invention relates to a flame-retardant sound-absorbing finish member that can be used in various applications.

一般建築物の内装、音響室やコンサートホール等の内装、工場建築物等の内装、モーター室、機械室等の設備機器類を設置する仕切りや部屋の内装、車両の内装等の各種仕上げ部材並びにカーテン及び装飾品を囲む材料等のインテリア部材には様々な材料が使用されているが、それらの仕上げ材として弾力性、反発性、クッション性に優れ、軽量で保温性、断熱性、防火性、防水性、耐薬品性を有し、且つ吸音性、遮音性、防振性を備えた難燃性吸音仕上げ部材はなかった。   Interior finishes for general buildings, interiors for sound rooms and concert halls, interiors for factory buildings, partitions for installing equipment such as motor rooms and machine rooms, interiors for rooms, various finishing members such as interiors for vehicles, Various materials are used for interior members such as materials surrounding curtains and ornaments, but they are excellent in elasticity, resilience, cushioning as their finishing materials, lightweight, heat retention, heat insulation, fire resistance, There was no flame-retardant sound-absorbing finish member having waterproofness, chemical resistance, and sound-absorbing, sound-insulating, and vibration-proofing properties.

従来より上記の内のいくつかの機能を備えた材料として多用されているのはグラスウールであった。該グラスウールは短いガラス繊維を集合させて形成した材料で、断熱性、吸音性及び防火性が有り、切断や曲げ等も自由にできる軽量な材料として所定厚の部材に形成して各種建築物を含め様々な箇所において多用されている。   Conventionally, glass wool has been widely used as a material having some of the above functions. The glass wool is a material formed by assembling short glass fibers, and has a heat insulating property, a sound absorbing property and a fireproof property, and is formed into a member with a predetermined thickness as a lightweight material that can be freely cut and bent. Widely used in various places including.

しかし、上記グラスウールは、人造鉱物繊維のため労働安全衛生法第57条の2に規定する通知対象物質となっている。該グラスウールを譲渡し、又は提供する者は、文書の交付その他厚生労働省令で定める方法により当該材料に関する下記の各項目を、譲渡し、又は提供する相手方に通知しなければならない、とされ、取り扱いのやっかいな材料となっている。

二 成分及びその含有量
三 物理的及び化学的性質
四 人体に及ぼす作用
五 貯蔵又は取扱い上の注意
六 流出その他の事故が発生した場合において講ずべき応急の措置
七 前各号に掲げるもののほか、厚生労働省令で定める事項
However, the glass wool is a notification target substance defined in Article 57-2 of the Industrial Safety and Health Law because it is an artificial mineral fiber. The person who assigns or provides the glass wool must notify the other party who assigns or provides the following items regarding the material by means of document delivery or other methods specified by the Ordinance of the Ministry of Health, Labor and Welfare. It is a troublesome material.
Name
Two components and their contents
(Iii) Physical and chemical properties
Four effects on the human body
(V) Notes on storage or handling
(Vi) Emergency measures to be taken in the event of a spill or other accident
(Vii) In addition to what is listed in the preceding items, matters specified by an Ordinance of the Ministry of Health, Labor and Welfare

また、製造時、吹き付け施工時及び解体時には、作業環境中の吸入性粉じん濃度が3.0mg/mを超える恐れがあり、国家検定の防じんマスクの着用が必要な材料となっている。更に、体の粘膜や皮膚への刺激症状が出やすいのでゴーグル等を装着して取り扱うことが勧められている。 In addition, when manufacturing, spraying, and dismantling, the concentration of inhalable dust in the work environment may exceed 3.0 mg / m 3 , and this is a material that requires wearing a nationally certified dust mask. Furthermore, it is recommended to wear goggles or the like because it is likely to cause irritation to the mucous membrane and skin of the body.

また、該グラスウールを材料とした部材は、細径のガラス繊維のため、体に触れるとチクチクし、袋状のもの等で囲繞するとか他の材料と積層するとかしないと取り扱いずらいものであった。しかし、その袋状のものや他の材料と併用すると、それらにより該グラスウールが有する断熱性、難燃性、防火性、吸音性、遮音性等の本来の機能を損なうおそれがあった。   In addition, since the glass wool material is a thin glass fiber, it will tingle when touched by the body and will be difficult to handle unless surrounded by a bag or laminated with other materials. It was. However, when used in combination with the bag-like material or other materials, they may impair the original functions of the glass wool such as heat insulation, flame retardancy, fire resistance, sound absorption, and sound insulation.

更に、炎にかざすと若干の煙や臭いが発生し、また、工場等の高熱部分に施工する際において、180度以上に過熱される部位にあっては、初期段階において煙が発生することも生じていた。   Furthermore, when it is held over a flame, some smoke or odor is generated, and when it is installed in a high heat part such as a factory, smoke may be generated at an initial stage in a part that is heated to 180 degrees or more. It was happening.

また、上記グラスウールの様々な欠点を考慮し、下記特許文献1のように、難燃断熱木材チップを採用する例もあるが、該難燃断熱木材チップはトロリーバケットコンベアで、高温高圧下で蒸煮し、すり潰し易くするためにボイラー等から最大蒸気圧力10kg/cm2の高温加圧蒸気が注入されるようにした蒸煮器に導き、柔らかく、且つより細かい形状の木材チップとする必要があった。 In consideration of various disadvantages of the glass wool, there is an example in which a flame-retardant and heat-insulated wood chip is employed as in Patent Document 1 below. The flame-retardant and heat-insulated wood chip is cooked at a high temperature and high pressure on a trolley bucket conveyor. However, in order to facilitate crushing, it was necessary to lead to a steamer in which high-temperature pressurized steam having a maximum steam pressure of 10 kg / cm 2 was injected from a boiler or the like, and to make the wood chips softer and finer.

該蒸煮器内においては、該木材チップを加圧蒸気内で所定方向に移動させつつ、スクリューフィーダ及びクロスコンベア、スチーミングチューブ等で蒸煮することになる。これらの加圧状態下で、蒸煮された木材チップは、該スチーミングチューブから排出される際、高温高圧状態で蒸煮され、且つ該スクリューフィーダ等でかき回され、その結果、柔らかく、且つより細かい形状の木材チップとするものである。   In the steamer, the wood chips are steamed with a screw feeder, a cross conveyor, a steaming tube or the like while moving in a predetermined direction in the pressurized steam. Under these pressurized conditions, the steamed wood chips are steamed in a high temperature and high pressure state when discharged from the steaming tube, and stirred with the screw feeder or the like, resulting in a softer and finer shape. Wood chips.

柔らかく、且つより細かい形状となった木材チップは、加圧型木材解繊機に導かれ、更に細かく解繊される。解繊された木質ファイバーは、ブローサイクロンに送られ、ここで、所定の送風空気により、該綿状木質ファイバーを水分率25%になるまで乾燥し、更に、ほぐし機・定量供給コンベアに送られる。該ほぐし機・定量供給コンベアでは、綿状木質ファイバーを解きほぐし、かさ密度を大きくし、更に、次の薬液含浸工程で、薬液が所定割合で含浸されるよう、300g/kgの所定量の木質ファイバーに定量され、その状態で薬液含浸装置に送られる。該薬液含浸装置は、薬液で満たされた薬液槽と、この薬液槽内に配置された逆凸状の上部メッシュコンベアと、前記逆凸に所定の間隔を有して対応する凹状下部メッシュコンベアにより、薬液槽内に投入され、薬液が含浸された木質ファイバーを挟み込む状態で、該薬液中を進むように構成され、最後に、脱液ローラにより、引き上げ、脱液される。   The soft and finer wood chips are guided to a pressure-type wood defibrator and further defibrated. The defibrated wood fiber is sent to a blow cyclone, where the cotton-like wood fiber is dried to a moisture content of 25% by a predetermined blowing air, and further sent to a loosening machine / quantitative supply conveyor. . In the unraveling machine / quantitative supply conveyor, the cotton-like wood fiber is unwound, the bulk density is increased, and further, in the next chemical solution impregnation step, a predetermined amount of wooden fiber of 300 g / kg is so impregnated at a predetermined rate. And is sent to the chemical impregnation apparatus in that state. The chemical solution impregnation apparatus includes a chemical solution tank filled with a chemical solution, a reverse convex upper mesh conveyor disposed in the chemical solution tank, and a concave lower mesh conveyor corresponding to the reverse convex with a predetermined interval. The liquid is introduced into the chemical solution tank, and the wood fiber impregnated with the chemical solution is sandwiched between the chemical solutions so as to advance through the chemical solution. Finally, the liquid is pulled up and drained by the liquid removal roller.

薬液処理された該木質ファイバーは、空気加熱器により加熱された空気内に所定量ずつ投入され、パイプ及びサイクロンセパレータ内を通過させることで難燃処理された難燃断熱木質ファイバーを得ることができる。   The wood fiber treated with the chemical solution is put into air heated by an air heater by a predetermined amount and passed through the pipe and the cyclone separator to obtain a flame-retardant heat-insulated wood fiber that has been flame-treated. .

上記のように、木質ファイバーよりなる難燃断熱材は、木材チップが材料のため、それを細かく解繊する工程や乾燥する工程、薬液処理工程、その後の解きほぐす工程等の多くの工程が必要となり、難燃断熱材とするには多大なコストと時間を必要とした。また、吸音性、遮音性、防振性等の効果は得られなかった。   As mentioned above, flame retardant insulation made of wood fiber is made of wood chips, so many steps such as finely defibrating, drying, chemical treatment, and subsequent unraveling are required. It took a great deal of cost and time to make a flame retardant insulation. In addition, effects such as sound absorption, sound insulation and vibration proofing were not obtained.

他方、特許文献2のように、短繊維と長繊維とを混綿し、横方向の張りと弾力性を有する布団綿が考案となる物品として登録されているが、本考案のように難燃吸音材を意図するものではなかった。   On the other hand, as in Patent Document 2, a futon cotton having a mixture of short fibers and long fibers and having lateral tension and elasticity is registered as an invented article. The material was not intended.

以下、図面に基づいて本考案の実施例を説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図1は、本考案の難燃性吸音仕上げ部材1の側面図を示している。該難燃性吸音仕上げ部材1は、いくつかの層よりなる積層部材で、その中心層には極細ポリエステルフィラメント2の柔軟な塊を芯材となるように配置し、その外側両面に中空ポリエステルファイバー3を積層し、更に、その外側に難燃繊維4を積層している。   FIG. 1 shows a side view of the flame-retardant sound-absorbing finish member 1 of the present invention. The flame-retardant sound-absorbing finishing member 1 is a laminated member composed of several layers, and a flexible lump of ultrafine polyester filaments 2 is arranged in the center layer so as to become a core material, and hollow polyester fibers are provided on both outer sides thereof. 3 and a flame retardant fiber 4 is laminated on the outside.

中芯層となる極細ポリエステルフィラメント2は、0.1〜1.5デニールの極細のポリエステルフィラメントを絡ませて塊状としたもので、難燃性吸音仕上げ部材1に音や振動が加わると該極細ポリエステルフィラメント2が揺れ、それにより音や振動エネルギーを減衰させて吸音効果を高めることが可能となる。   The ultra-fine polyester filament 2 serving as the core layer is formed by tangling an ultra-fine polyester filament of 0.1 to 1.5 denier, and when the flame retardant sound absorbing finish member 1 is subjected to sound or vibration, the ultra-fine polyester filament 2 The filament 2 sways, thereby attenuating sound and vibration energy and enhancing the sound absorption effect.

中空ポリエステルファイバー3は、繊維の中心に空間の有る筒状のポリエステルで、通常の綿より軽く、更に、中空となっているため他のポリエステルと同一嵩での比較では一層の軽さを得ることができる。また、弾力性が豊かでクッション材として最適である。   The hollow polyester fiber 3 is a cylindrical polyester having a space in the center of the fiber, which is lighter than normal cotton and is hollow, so that it is lighter in comparison with other polyesters in the same volume. Can do. In addition, it is rich in elasticity and optimal as a cushioning material.

更に重要なことは、中空部分は熱伝導率が低くなるので難燃性吸音仕上げ部材1の外部から加えられた熱が中芯部に伝達されることを防止することができ、該難燃性吸音仕上げ部材1の急激な温度上昇を避けることが可能となる。   More importantly, since the thermal conductivity of the hollow portion is low, heat applied from the outside of the flame-retardant sound-absorbing finish member 1 can be prevented from being transmitted to the core portion, and the flame-retardant property can be prevented. It is possible to avoid a rapid temperature rise of the sound absorbing finish member 1.

上記中空ポリエステルファイバー3の外側に難燃繊維4を積層しているが、該難燃繊維4は、木綿、真綿、パンヤ、麻繊維、羊毛繊維及び合成繊維のいずれかから選択することができる。   Although the flame retardant fiber 4 is laminated on the outer side of the hollow polyester fiber 3, the flame retardant fiber 4 can be selected from cotton, true cotton, bread, hemp fiber, wool fiber, and synthetic fiber.

難燃繊維4は、少なくとも長さが50mm以上の多数本の繊維を絡ませたもので、その層厚は、15mm乃至40mmとする。全体の部材厚を100mmとすると30mm厚のものが最適である。   The flame retardant fiber 4 is a fiber in which a large number of fibers having a length of at least 50 mm are entangled, and the layer thickness is 15 mm to 40 mm. When the total member thickness is 100 mm, a member having a thickness of 30 mm is optimal.

難燃繊維4は、上記した様々な繊維に難燃剤5を塗布或いは含浸により各繊維1本1本の周囲に該難燃剤5を囲繞して一体化させることにより難燃化させている。   The flame retardant fiber 4 is made flame retardant by surrounding and integrating the flame retardant 5 around each fiber by applying or impregnating the above various fibers with the flame retardant 5.

上記難燃剤5としては、有機難燃剤や無機難燃剤等を使用する。有機難燃剤としては、ポリリン酸アンモニウム等のポリリン酸塩系やリン酸エステル系等のリン系難燃剤或いは窒素系、ハロゲン系、臭素系の難燃剤が挙げられる。また、無機難燃剤としては、ホウ素化合物、水酸化アルミニウム、水酸化マグネシウム、三酸化アンチモン、アンチモン酸ソーダ、ジルコニウム化合物、硼砂、硼酸亜鉛、三酸化モリブデン、ケイ酸ナトリウム、或いは上記化合物の錯体である複合無機物が挙げられる。中でも特に、火災時や使用後の焼却処分時に有害なハロゲン系ガスを発生しない非ハロゲン系の難燃剤、特にポリリン酸塩系難燃剤が好ましい。   As the flame retardant 5, an organic flame retardant, an inorganic flame retardant, or the like is used. Examples of the organic flame retardant include phosphorus-based flame retardants such as polyphosphates such as ammonium polyphosphate and phosphoric ester-based flame retardants, and nitrogen-based, halogen-based, and bromine-based flame retardants. Examples of the inorganic flame retardant include boron compounds, aluminum hydroxide, magnesium hydroxide, antimony trioxide, sodium antimonate, zirconium compounds, borax, zinc borate, molybdenum trioxide, sodium silicate, or complexes of the above compounds. A composite inorganic substance is mentioned. Among these, non-halogen flame retardants, particularly polyphosphate flame retardants, which do not generate harmful halogen gases during fires or incineration after use are particularly preferable.

難燃剤5の添加量は、繊維100重量部当たり1〜50重量部であるのが好ましい。添加量が少ないと充分な難燃性が得られず、一方、難燃剤の添加量が多いと、重くなる。   The addition amount of the flame retardant 5 is preferably 1 to 50 parts by weight per 100 parts by weight of the fiber. If the addition amount is small, sufficient flame retardancy cannot be obtained, while if the addition amount of the flame retardant is large, it becomes heavy.

上記難燃繊維4を中空ポリエステルファイバー3の両面側に積層後、更に上記と同様の難燃剤5を吹き付け、乾燥させる。難燃剤5を吹き付けることにより製造時に生じた難燃性のばらつきを防止すると同時に、より一層均一強化された優れた難燃部材を完成させることができる。   After laminating the flame retardant fiber 4 on both sides of the hollow polyester fiber 3, the same flame retardant 5 as above is sprayed and dried. By spraying the flame retardant 5, it is possible to prevent a variation in flame retardance that occurs during production, and at the same time, complete an excellent flame retardant member that is further uniformly reinforced.

なお、図1では左右の端部側面が積層状態として露出しているが、施工する部材端部や使用場所によっては当該端部へ中空ポリエステルファイバー3及び難燃繊維4の各層を廻し込んで成型することにより端部側面からの断熱、防火、防音性能等も良好なものとすることができる。   In FIG. 1, the side surfaces of the left and right end portions are exposed in a laminated state, but depending on the end portion of the member to be constructed and the place of use, the hollow polyester fiber 3 and the flame retardant fiber 4 are wound around the end portion and molded By doing so, the heat insulation, fireproofing, soundproofing performance, etc. from the end side surface can be made good.

100mm厚の従来のグラスウール1,000mm×1,000mmの板状部材のものと100mm厚の本考案の実施例の内、麻繊維を難燃化し、更に、リン系難燃剤を吹き付け乾燥させた難燃性吸音仕上げ部材1,000mm×1,000mmの板状部材のものとを比較してみた。   Of the 100 mm thick conventional glass wool 1,000 mm × 1,000 mm plate-like member and the 100 mm thick embodiment of the present invention, the hemp fiber is made flame retardant, and further, the phosphorus flame retardant is sprayed and dried A comparison was made with a plate-like member of a flammable sound-absorbing finish member of 1,000 mm × 1,000 mm.

It can be used for interior materials such as interiors around the source of the vehicle, interiors of vehicles, materials surrounding curtains and ornaments, etc., and it has excellent elasticity, resilience, cushioning as a finishing material, light weight, heat retention, heat insulation It has become possible to obtain a flame-retardant sound-absorbing finish member that has heat resistance, fire resistance, water resistance, and chemical resistance, and also has sound absorption properties, sound insulation properties, and vibration proof properties.

図2は、本考案の難燃性吸音仕上げ部材6の他の実施例の側面図を示している。実施例1の難燃性吸音仕上げ部材1と同様、いくつかの層を積層した部材を上下に2枚重ねて一体化したものである。   FIG. 2 shows a side view of another embodiment of the flame retardant sound absorbing finish member 6 of the present invention. Similar to the flame-retardant sound-absorbing finishing member 1 of Example 1, two members laminated in layers are integrated one above the other.

製造時における製造し易さ或いは施工時における施工し易さを可能とするため同一の積層難燃性吸音仕上げ部材を製造箇所や施工箇所で重ね合わせて一体化したもので、実施例1と同様の厚さとなるように形成している。   The same laminated flame-retardant sound-absorbing finish member is integrated by overlapping at the manufacturing location and construction location to enable ease of manufacture at the time of manufacture or ease of installation at the time of construction. It is formed to have a thickness of.

各積層部材7、8は、その中心層に極細ポリエステルフィラメント9a、9bが芯材となるように配置し、その外側両面に中空ポリエステルファイバー10a、10b、10c、10dを積層し、更にその外側両面に難燃繊維11a、11b、11c、11dを積層している。   Each of the laminated members 7 and 8 is arranged so that the ultrafine polyester filaments 9a and 9b serve as a core material in the center layer thereof, and the hollow polyester fibers 10a, 10b, 10c, and 10d are laminated on both outer sides thereof, and the outer both sides thereof are further laminated. In addition, flame retardant fibers 11a, 11b, 11c, and 11d are laminated.

上記極細ポリエステルフィラメント9a、9b、中空ポリエステルファイバー10a〜10d及び難燃繊維11a〜11dの材料は、実施例1と同様である。   The materials of the ultrafine polyester filaments 9a and 9b, the hollow polyester fibers 10a to 10d, and the flame retardant fibers 11a to 11d are the same as those in the first embodiment.

また、各積層部材7、8の部材厚が実施例1と比較して半分となるので、それに応じて各々の層厚も半分としている。   Moreover, since the member thickness of each laminated member 7 and 8 becomes half compared with Example 1, each layer thickness is also made half according to it.
