Description

本発明は、ロックウール、グラスウール等の建築用あるいは構築用の繊維系断熱材として用いられる繊維マットの改良に係り、環境にやさしい優れた特性を有するとともに加工性、運搬性、施工に際しての作業性及び取り扱い性を格段に向上させた繊維マットに関する。   The present invention relates to an improvement of a fiber mat used as a fiber-based heat insulating material for construction or construction such as rock wool and glass wool, and has excellent environment-friendly characteristics and processability, transportability, workability during construction. And a fiber mat with greatly improved handling.

建築用の断熱材として広く用いられているロックウール、グラスウール等は、スラグ・玄武岩やガラス等を溶融しこれを細い繊維状にし、さらに綿状に形成した上で厚さ数ｃｍの板状に成形している。このようにして製造された断熱材の原反を、そのまま現場で施工したり、現場での施工に適した予め各種の規格サイズや所要のサイズに断裁したりした上で、これを現場に運搬して取付施工するものである。   Rock wool, glass wool, etc., widely used as heat insulating materials for construction, melt slag, basalt, glass, etc. into thin fibers, and then form them into a cotton-like plate shape Molding. The raw material of the heat insulating material manufactured in this way can be applied on-site as it is, or cut into various standard sizes and required sizes suitable for on-site construction in advance, and then transported to the site. And install it.

この断熱材は、断熱性能に優れるとともに、高強度で、かつ不燃性も発揮し極めて有用な材料ではあるが、取り扱う際に中に含まれている細かな繊維片が粉塵となって飛散しやすく、これを吸うことがないように作業者はマスクを使用していて問題ないが、これが身体に被着するとチクチクする不快感を生じることから、断熱材から繊維片が飛散しないようにポリエチレン製の袋に収納し使用することが一般に行われている。
特開２０００−６９１８公報 This heat insulating material has excellent heat insulating performance, high strength, and non-flammability, and is an extremely useful material, but the fine fiber pieces contained in it are easily scattered as dust. In order not to inhale this, it is no problem that the worker uses a mask, but this causes a tingling discomfort when it is attached to the body, so that the fiber pieces do not scatter from the heat insulating material. It is common practice to store and use in a bag.
JP 2000-6918 A

この優れたマット状の繊維系断熱材であるが、以下のような問題点があった。
すなわち、予め各種サイズに断裁して袋詰めするといっても、そのサイズの種類は１００種以上あることから、それぞれのサイズ用のポリエチレン袋を多種揃えるという多大な手間と労苦を要するものであった。さらに、袋詰めされた断熱材であっても、細かな繊維片が袋の隙間から漏れ出てきたり、袋が破れたりした場合には、繊維片が飛散して前述の問題点を抜本的に解決することは出来なかった。 This excellent mat-like fiber-based heat insulating material has the following problems.
That is, even if it is cut into various sizes in advance and packed in bags, there are more than 100 types of sizes, which requires a great deal of labor and labor to prepare a variety of polyethylene bags for each size. . Furthermore, even in the case of heat insulation material packed in a bag, if fine fiber pieces leak out from the gaps in the bag or the bag is torn, the fiber pieces will scatter and drastically eliminate the above problems. It could not be solved.

そこで本発明の目的は、断熱材をポリエチレン袋に袋詰めしなくとも繊維片が飛散することがなく、環境にやさしい優れた特性を有し、所要の断熱・難燃効果を発揮できることは勿論のこと作業性・取り扱い性にも優れた繊維マット系の断熱材を提供することを目的とする。   Therefore, the object of the present invention is that the fiber pieces do not scatter even if the heat insulating material is not packed in a polyethylene bag, has excellent characteristics that are environmentally friendly, and can exhibit the required heat insulation and flame retardant effects. An object of the present invention is to provide a fiber mat type heat insulating material which is excellent in workability and handling.

上記目的を達成するため、本発明の繊維マットは、ロックウール、グラスウール等の繊維からなるマット体の表面に繊維片飛散防止加工を施したことを特徴とする。   In order to achieve the above object, the fiber mat of the present invention is characterized in that the surface of a mat body made of fibers such as rock wool and glass wool is subjected to a fiber piece scattering prevention process.

また、飛散防止加工手段は、ロックウール、グラスウール等の繊維からなるマット体の表面に膜体を形成することを特徴とする。   Further, the scattering prevention processing means is characterized in that a film body is formed on the surface of a mat body made of fibers such as rock wool and glass wool.

また、マット体は、建築あるいは構築用の断熱材として使用されることを特徴とする。   The mat body is used as a heat insulating material for construction or construction.

また、膜体には、難燃性を発揮させるべく防炎剤が混入されてなることを特徴とする。   Further, the film body is characterized in that a flameproofing agent is mixed in order to exhibit flame retardancy.

また、膜体は、エチレン・酢酸ビニル系共重合体エマルジョン等の接着剤を塗布することにより形成されることを特徴とする。   The film body is formed by applying an adhesive such as an ethylene / vinyl acetate copolymer emulsion.

本発明によれば、繊維マットは表面に繊維片飛散防止加工を施されていることからポリエチレン製の袋に入れずとも、粉塵となって飛散することなく、したがって各種作業中あるいは搬送中に身体に被着しチクチクする等の不快感を生ずることは一切なく、環境にやさしいものである。
また当然のことながら断熱効果は損われることがないことから建築あるいは構築用の断熱材として極めて有用である。 According to the present invention, since the fiber mat has a fiber piece scattering prevention process on its surface, it does not scatter as dust even if it is not put in a polyethylene bag. It is environmentally friendly without causing any discomfort such as being attached to the skin.
Also, as a matter of course, since the heat insulating effect is not impaired, it is extremely useful as a heat insulating material for construction or construction.

また、本発明の繊維マットは、繊維片飛散防止加工を施されていることからポリエチレン製の袋に入れずとも所望のあらゆるサイズに断裁して所望数量おくことができ、多種サイズのポリエチレン製袋を多数用意し袋詰めするという多大な労苦を伴う極めて不効率・不経済な作業が不要となる。   In addition, since the fiber mat of the present invention is subjected to a fiber piece scattering prevention process, it can be cut into any desired size without being put in a polyethylene bag, and can be put in a desired quantity. A very inefficient and uneconomical work that requires a great deal of labor to prepare and pack a large number of bags becomes unnecessary.

また、繊維片がポリエチレン製袋の隙間から漏れたり、施工現場で袋詰め断熱材の袋が破れて繊維片が飛散したりすることも勿論ない。   In addition, there is no possibility that the fiber piece leaks from the gap between the polyethylene bags, or the bag of the bag-filled heat insulating material is broken at the construction site and the fiber piece is scattered.

さらに膜体構成材料には、難燃性を発揮すべく防炎剤が混入されていることから、たとえば塗剤として接着作用のあるエチレン・酢酸ビニル系共重合体エマルジョン等の化学剤を用いても好適な断熱効果を発揮できることは勿論のこと、充分な難燃効果を発揮することができる。   Furthermore, since the flame retardant is mixed in the film body constituting material to exhibit flame retardancy, for example, a chemical agent such as an ethylene / vinyl acetate copolymer emulsion having an adhesive action is used as a coating agent. In addition, a sufficient heat-insulating effect can be exhibited, as well as a sufficient flame-retardant effect.

図１、図２は本発明の一実施例を示し、１は繊維マットでありロックウール、グラスウール等を溶融しこれを繊維状にし、さらに綿体２に形成した上で所望の厚さ及び幅径に成形している。   FIGS. 1 and 2 show an embodiment of the present invention. Reference numeral 1 denotes a fiber mat, which is made by melting rock wool, glass wool or the like to form a fiber, and further forming it into a cotton body 2 and then having a desired thickness and width. Molded to a diameter.

３は繊維マット表面にコーティングされた膜体であり、膜体３形成材料としては、たとえばエチレン・酢酸ビニル共重合体エマルジョン等の接着剤を用いてもよい。
尚、膜体形成材料としては繊維マット表面に接着されかつ表面に膜が形成され、繊維マットの繊維片の飛散が防止される作用を発揮されるものであればいかなる材料であってもよい。 Reference numeral 3 denotes a film body coated on the surface of the fiber mat. As the film body 3 forming material, an adhesive such as an ethylene / vinyl acetate copolymer emulsion may be used.
The material for forming the film body may be any material as long as it is adhered to the surface of the fiber mat and a film is formed on the surface so that the fiber mat can be prevented from being scattered.

４は膜体３形成用の塗剤５を噴霧するスプレーである。尚、本実施例にあっては、塗剤を繊維マット表面にコーティングする手段としてスプレーを用いたが、勿論これに限定されることはなく、刷毛塗りや適宜な他の手段を用いてもよいものである。   A spray 4 sprays the coating 5 for forming the film body 3. In this example, spray was used as a means for coating the surface of the fiber mat with the coating agent. However, the present invention is not limited to this, and brushing or other appropriate means may be used. Is.

また膜体形成用の塗剤として前記エチレン・酢酸ビニル共重合体エマルジョン等が用いられた場合には、難燃性能に影響を与えることが懸念されるが、本発明にあっては塗剤に防炎剤が混入されていることから、充分な難燃性を確保できる。   Further, when the ethylene-vinyl acetate copolymer emulsion or the like is used as a coating material for forming a film body, there is a concern that the flame retardant performance may be affected. Since the flameproofing agent is mixed, sufficient flame retardancy can be secured.

尚、塗剤の一実施例としてのエチレン・酢酸ビニル共重合体エマルジョンは、接着剤としてよく用いられているが、可塑剤や溶剤を一切含まない環境にやさしい水溶性の表面処理剤である。このエマルジョンの膜体は、耐水性、耐候性、耐老化性に優れ、かつある程度の柔軟性も備えることから、通常の塗料のごとく、乾燥した膜体が剥離する恐れもないものである。そして、このエマルジョンを断熱材にスプレーにより塗布するために、水で溶いて適切な粘度としている。   An ethylene / vinyl acetate copolymer emulsion as an example of a coating agent is often used as an adhesive, but is an environmentally friendly water-soluble surface treatment agent that does not contain any plasticizer or solvent. Since the film body of this emulsion is excellent in water resistance, weather resistance and aging resistance and has a certain degree of flexibility, there is no fear that the dried film body will peel off like a normal paint. And in order to apply | coat this emulsion to a heat insulating material with a spray, it melt | dissolves with water and it is set as the appropriate viscosity.

尚、上述した実施例にあっては建築用の断熱材について説明したが、もちろんこれに用途を限定されることはなく、建築用以外の断熱材についても適用することができるものである。   In addition, in the Example mentioned above, although the heat insulating material for buildings was demonstrated, of course, a use is not limited to this and it can apply also to heat insulating materials other than for buildings.
