Abstract
Description
本発明は、屋内に敷設される床材の改良に関する。 The present invention relates to an improvement in flooring laid indoors.
例えば、畳における畳床のように床材のマトリックスとして使用されるインシュレーションボードは、木質繊維板であって、一般的に湿式抄造法で作られる。具体的には、木質繊維，バインダー，薬剤等を多量の水に分散させ、金網で抄き上げて得られた湿潤マットを乾燥して製造される。 For example, an insulation board used as a flooring matrix like a tatami floor in a tatami mat is a wood fiber board, and is generally made by a wet papermaking method. Specifically, it is produced by drying a wet mat obtained by dispersing a wood fiber, a binder, a drug, and the like in a large amount of water and drawing it with a wire mesh.
ここで、上述のような木質繊維板の製造工程では系内の水が循環使用されているため、その系内の水に木質繊維からの溶出物や製品に定着しなかった薬剤等が蓄積するようになる。そして、系内の水を長時間循環させると、係る薬剤等の蓄積や蓄積した薬剤等の腐敗・発酵などにより独特の臭気が生じ、抄造した木質繊維板にその臭気が残留するようになる。人によって感じ方の度合いに差は有るものの、一般的に係る臭気は快い匂いではない。このため、当該臭気が顕著な場合には、木質繊維板を畳床として施工した後に苦情やクレームが発生することがある。 Here, since the water in the system is circulated and used in the manufacturing process of the wood fiber board as described above, the eluate from the wood fiber, the medicine not fixed to the product, etc. accumulate in the water in the system. It becomes like this. When the water in the system is circulated for a long time, a unique odor is generated due to accumulation of the drug and the like, decay and fermentation of the accumulated drug, etc., and the odor remains on the paper-made wood fiberboard. Although there is a difference in the degree of feeling depending on the person, generally the odor is not a pleasant odor. For this reason, when the said odor is remarkable, a complaint and a complaint may generate | occur | produce after constructing a wooden fiber board as a tatami floor.
なお、従来は、畳表として独特の強い芳香を持つイ草が使用されていたため、畳床となる木質繊維板の臭いが目立つことはほとんどなかったが、畳表として紙に撚りをかけた無臭の筒状抄繊糸が多用されて以降、係る問題が顕在化してきた。
そこで、上述のような臭気への対策として、下記の特許文献１（日本国・特開２００５−１９９５５３号公報）には、木質繊維板に消臭剤や香料を塗布し、木質繊維板からの臭気を低減或いは抑制する技術が開示されている。
In the past, moss with a unique strong fragrance was used as a tatami mat, so the smell of the wooden fiberboard that became the tatami floor was hardly noticeable, but the odorless tube that twisted the paper as a tatami mat Such problems have become apparent since the fiber-like yarn has been frequently used.
Therefore, as a countermeasure against the odor as described above, the following Patent Document 1 (Japan, Japanese Patent Application Laid-Open No. 2005-199553) applies a deodorant and a fragrance to a wooden fiberboard, Techniques for reducing or suppressing odor are disclosed.
上記従来技術のように、臭気対策として木質繊維板に消臭剤や香料等をダイレクトに塗布した場合、塗布直後から高い臭気低減或いは抑制効果を発揮し、係る効果は漸減しながら所定の期間継続する。したがって、製造後に販売店で長期在庫された後、施工された場合は効果を発揮することができない。
そのような中、床材として使用する木質繊維板の臭気の低減或いは抑制が可能な期間を更に延ばしたいと言ったニーズが出てきているが、木質繊維板に消臭剤や香料等をダイレクトに塗布する方法では、そのような期間を延ばすためには、塗布する消臭剤や香料等の量を増やさなければならない。そうすると、特に香料を用いた場合には、塗布直後からかなり強い芳香が発せられるようになり、臭気の低減或いは抑制効果は高いものの、意図しない香料の芳香によって新たな不快感を与えてしまうと言った問題やコストアップが生じ得る。
When the deodorant or fragrance is directly applied to the wood fiber board as a countermeasure against odor as in the above prior art, a high odor reduction or suppression effect is exhibited immediately after application, and the effect continues for a predetermined period while gradually decreasing. To do. Therefore, the effect cannot be exhibited when it is constructed after being manufactured and stocked for a long time at a store.
Under such circumstances, there is a need to further extend the period during which the odor of wood fiberboard used as flooring can be reduced or suppressed, but deodorants and fragrances are directly applied to the wood fiberboard. In order to extend such a period, it is necessary to increase the amount of deodorant or fragrance to be applied. Then, especially when a fragrance is used, a fairly strong fragrance will be emitted immediately after application, and although the odor reduction or suppression effect is high, it is said that a new discomfort is given by the unintended fragrance fragrance. Problems and cost increases.
それゆえに、本発明の主たる課題は、床材のマトリックスとなる木質繊維板から放散される臭気を長期間継続して低減或いは抑制することが可能な床材を提供することである。更に、臭気の低減或いは抑制に止まらず、木質繊維板に付与する機能性材料の効果を長期間効率的に発揮させることが可能な床材を提供することである。 Therefore, a main object of the present invention is to provide a flooring material capable of continuously reducing or suppressing the odor emitted from the wood fiber board as a flooring material matrix for a long period of time. Furthermore, the present invention is to provide a flooring material capable of effectively exhibiting the effect of the functional material imparted to the wood fiber board for a long period of time without being limited to the reduction or suppression of the odor.
上記の課題を達成するため、本発明は、例えば、図１に示すように、木質繊維板１２からなる床材１０を次のように構成した。
すなわち、木質繊維板１２の少なくとも上表面側に、消臭剤，芳香剤，精油，香料，防虫剤及び抗菌剤からなる群より選ばれる少なくとも１つの機能性材料を芯物質として内包したマイクロカプセル１４が配設される。
In order to achieve the above object, for example, as shown in FIG. 1, in the present invention, a flooring 10 made of a wood fiber board 12 is configured as follows.
That is, the microcapsule 14 in which at least one functional material selected from the group consisting of a deodorant, a fragrance, an essential oil, a fragrance, an insect repellent, and an antibacterial agent is included as a core substance on at least the upper surface side of the wood fiber board 12. Is disposed.
本発明は、次の作用を奏する。
消臭剤，芳香剤，精油，香料，防虫剤及び抗菌剤からなる群より選ばれる少なくとも１つの機能性材料を芯物質としてマイクロカプセル１４に内包させているので、このマイクロカプセル１４を木質繊維板１２に配設させた直後ではなく、木質繊維板１２からなる床材１０を床材として施工し、床材の上を歩いた直後から上記の機能性材料を徐放させることができる。したがって、製造後長期に亘り倉庫で在庫しても機能性材料は放出されず、施工後に人が歩いてマイクロカプセル１４が破裂した直後から効果を発揮し、マイクロカプセル１４が破裂されずに存在する限り、効果は継続する。加えて、このマイクロカプセル１４を木質繊維板１２の少なくとも上表面側に配設しているので、床材１０を使用する際に木質繊維板１２から徐放される機能性材料の利用効率を極大化させることができる。
The present invention has the following effects.
Since at least one functional material selected from the group consisting of deodorant, fragrance, essential oil, fragrance, insect repellent and antibacterial agent is contained in the microcapsule 14 as a core substance, the microcapsule 14 is made of a wood fiber board. The functional material can be gradually released immediately after the floor material 10 made of the wood fiber board 12 is constructed as a floor material, and immediately after walking on the floor material. Therefore, the functional material is not released even if stocked in the warehouse for a long time after production, and the microcapsule 14 is present without being ruptured, which is effective immediately after a person walks after construction and the microcapsule 14 ruptures. As long as the effect continues. In addition, since the microcapsules 14 are disposed on at least the upper surface side of the wood fiber board 12, the use efficiency of the functional material that is gradually released from the wood fiber board 12 when the flooring 10 is used is maximized. It can be made.
本発明においては、レーザー回折・散乱法にて測定した上記マイクロカプセル１４の平均粒径を５０μｍ以上で且つ５００μｍ以下とするのが好ましい。上記マイクロカプセル１４の平均粒径が５０μｍ未満の場合には、相対的に膜厚が大きくなるため、床材１０の上を人が歩いて踏んだ際などに発生する圧縮応力でマイクロカプセル１４を破裂させるのが困難になり、逆に、マイクロカプセル１４の平均粒径が５００μｍを超える場合には、上記の圧縮応力で簡単に破裂させて内部の機能性材料を徐放させることができるようになるが、バインダーを用いずにマイクロカプセル１４を木質繊維板１２の上表面側に配設する場合、床材１０を施工現場へ運搬する際などに、当該マイクロカプセル１４が木質繊維板１２の上表面側から容易に脱落して歩留りが悪くなるからである。 In the present invention, it is preferable that the average particle diameter of the microcapsules 14 measured by a laser diffraction / scattering method is 50 μm or more and 500 μm or less. When the average particle diameter of the microcapsules 14 is less than 50 μm, the film thickness becomes relatively large. Therefore, the microcapsules 14 are caused by compressive stress generated when a person walks on the flooring 10. When the average particle size of the microcapsule 14 exceeds 500 μm, it is difficult to rupture, so that it can be easily ruptured by the compressive stress so that the internal functional material can be released gradually. However, when the microcapsule 14 is disposed on the upper surface side of the wood fiber board 12 without using a binder, the microcapsule 14 is placed on the wood fiber board 12 when the flooring 10 is transported to the construction site. This is because it easily drops off from the surface side and the yield deteriorates.
また、第２の発明に係る床材１０は、上記発明に加え、前記木質繊維板１２の表面を、通気性を有する表装材１８で被覆したことを特徴とするものである。とりわけ、表装材１８を畳表とし、木質繊維板１２を畳床とする、つまり、床材１０を畳とするのが好適である。 Moreover, the flooring 10 according to the second invention is characterized in that, in addition to the above-described invention, the surface of the wood fiber board 12 is covered with a surface covering material 18 having air permeability. In particular, it is preferable that the covering material 18 is a tatami mat and the wood fiber board 12 is a tatami floor, that is, the flooring 10 is a tatami mat.
なお、本発明は、後述する実施形態に記載された特有の構成を付加することが好ましい。 In addition, it is preferable to add the specific structure described in embodiment mentioned later to this invention.
本発明によれば、床材のマトリックスとなる木質繊維板から放散される臭気を長期間継続して低減或いは抑制できることに止まらず、木質繊維板に付与する機能性材料の効果を長期間効率的に発揮させることが可能な床材を提供することができる。 According to the present invention, the effect of the functional material imparted to the wooden fiberboard can be effectively improved over a long period of time, because the odor emitted from the wooden fiberboard serving as the matrix of the flooring can be continuously reduced or suppressed for a long period of time. The flooring which can be made to exhibit can be provided.
以下、本発明の一実施形態を図面を用いて説明する。図１は、本発明の床材１０の一例を示す模式図である。この図が示すように、本発明の床材１０は、木質繊維板１２を有する。
なお、本実施形態(図示実施形態)では、床材１０を畳として構成している場合を示している。
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view showing an example of a flooring 10 of the present invention. As shown in this figure, the flooring 10 of the present invention has a wood fiber board 12.
In the present embodiment (illustrated embodiment), the floor material 10 is configured as a tatami mat.
木質繊維板１２は、床材１０のマトリックスとなるもので、木材チップを蒸煮・解繊して得た木質繊維をマット状に成形して固めた板材で、具体的には、インシュレーションボード，中密度繊維板(ＭＤＦ)及びハードボードなどを挙げることができる。このうち、インシュレーションボード及びハードボードは、木質繊維のマットを形成する際に水を媒体とする湿式法で製造され、中密度繊維板は、木質繊維のマットを形成する際に気流を用いる乾式法で製造されるのが一般的である。
なお、図示実施形態のように、床材１０を畳とする場合には、畳床となる木質繊維板１２として、相対的に密度が低くクッション性の高いインシュレーションボードを用いるのが特に好適である。
そして、この木質繊維板１２の少なくとも上表面側には、マイクロカプセル１４が配設されている。
The wood fiber board 12 serves as a matrix of the flooring 10 and is a board material obtained by molding and hardening wood fibers obtained by steaming and defibrating wood chips. Examples thereof include medium density fiberboard (MDF) and hardboard. Among them, the insulation board and the hard board are manufactured by a wet method using water as a medium when forming a wood fiber mat, and the medium density fiber board is a dry type that uses an air flow when forming a wood fiber mat. Generally, it is manufactured by the method.
In addition, when the flooring 10 is a tatami mat as in the illustrated embodiment, it is particularly preferable to use an insulation board having a relatively low density and a high cushioning property as the wood fiber board 12 serving as a tatami floor. is there.
Microcapsules 14 are disposed on at least the upper surface side of the wood fiber board 12.
マイクロカプセル１４は、木質繊維板１２に、消臭剤，芳香剤，精油，香料，防虫剤及び抗菌剤からなる群より選ばれる少なくとも１つの機能性材料を付与するためのもので、これらの機能性材料を芯物質とし、この芯物質をゼラチン，尿素樹脂，メラミン樹脂，ウレタン樹脂及びポリウレア樹脂などからなる壁材(被膜物質)で包み込んだ完全閉口型の樹脂カプセルである。
このマイクロカプセル１４の大きさは、レーザー回折・散乱法にて測定した平均粒径が５０μｍ〜５００μｍの範囲内であるの好ましく、より好ましくは、１００μｍ〜４００μｍの範囲内である。マイクロカプセル１４の平均粒径が５０μｍ未満の場合には、相対的に膜厚が大きくなるため、床材１０の上を人が歩いて踏んだ際などに発生する圧縮応力でマイクロカプセル１４を破裂させるのが困難になり、逆に、マイクロカプセル１４の平均粒径が５００μｍを超える場合には、バインダーを用いずにマイクロカプセル１４を木質繊維板１２の上表面側に配設する場合、床材１０を施工現場へ運搬する際などに当該マイクロカプセル１４が木質繊維板１２の上表面側から容易に脱落して歩留りが悪くなるからである。
このマイクロカプセル１４の芯物質となる機能性材料、すなわち、消臭剤，芳香剤，精油，香料，防虫剤及び抗菌剤からなる群より選ばれる少なくとも１つは、天然のものであってもよいし、化学合成したものであってもよい。
The microcapsule 14 is for imparting to the wood fiber board 12 at least one functional material selected from the group consisting of deodorant, fragrance, essential oil, fragrance, insect repellent and antibacterial agent. This is a completely closed type resin capsule in which a core material is used as a core material, and the core material is wrapped with a wall material (coating material) made of gelatin, urea resin, melamine resin, urethane resin, polyurea resin or the like.
The size of the microcapsule 14 is preferably such that the average particle diameter measured by the laser diffraction / scattering method is in the range of 50 μm to 500 μm, more preferably in the range of 100 μm to 400 μm. When the average particle size of the microcapsules 14 is less than 50 μm, the film thickness becomes relatively large, so that the microcapsules 14 are ruptured by a compressive stress generated when a person walks on the flooring 10. On the contrary, when the average particle diameter of the microcapsules 14 exceeds 500 μm, when the microcapsules 14 are disposed on the upper surface side of the wood fiber board 12 without using a binder, flooring This is because the microcapsule 14 easily falls off from the upper surface side of the wood fiber board 12 when the 10 is transported to the construction site, and the yield deteriorates.
The functional material serving as the core substance of the microcapsule 14, that is, at least one selected from the group consisting of deodorant, fragrance, essential oil, fragrance, insect repellent, and antibacterial agent may be natural. However, it may be chemically synthesized.
木質繊維板１２に対するマイクロカプセル１４の塗布量は、特に限定されるものではなく、芯物質となる機能性材料の種類や塗布される木質繊維板１２の種類に応じて適宜設定される。また、木質繊維板１２の上表面側にマイクロカプセル１４を配設する方法としては、先ず始めに水などの分散媒に所定の濃度でマイクロカプセル１４を分散させた分散液を準備し、この分散液をスプレー，刷毛又はロールコーターと言った公知の方法で木質繊維板１２の上表面側に塗布する。すると、木質繊維板１２を構成する木質繊維の毛細管現象によって分散媒が木質繊維板１２の内部へと浸透し、それに伴ってマイクロカプセル１４も(分散媒と共に)移動して、木質繊維同士の交絡によって形成された隙間へと入り込むようになる。その後、乾燥等で分散媒を除去することによって、木質繊維板１２の上表面側へのマイクロカプセル１４の配設が完了する。なお、上述の例では、機能性材料の分散液として分散媒に機能性材料のみを分散させたものを示したが、必要に応じてバインダーなどの他の薬品を配合するようにしてもよい。 The amount of the microcapsule 14 applied to the wood fiber board 12 is not particularly limited, and is appropriately set according to the type of functional material serving as a core substance and the type of wood fiber board 12 to be applied. As a method of disposing the microcapsules 14 on the upper surface side of the wood fiber board 12, first, a dispersion liquid in which the microcapsules 14 are dispersed at a predetermined concentration in a dispersion medium such as water is prepared. The liquid is applied to the upper surface side of the wood fiber board 12 by a known method such as spray, brush or roll coater. Then, the dispersion medium penetrates into the interior of the wood fiber board 12 due to the capillary phenomenon of the wood fibers constituting the wood fiber board 12, and the microcapsule 14 (with the dispersion medium) moves accordingly, and the wood fibers are entangled. It enters into the gap formed by. Thereafter, the dispersion medium is removed by drying or the like, whereby the arrangement of the microcapsules 14 on the upper surface side of the wood fiber board 12 is completed. In the above-described example, the functional material dispersion liquid is a dispersion medium in which only the functional material is dispersed. However, other chemicals such as a binder may be blended as necessary.
本発明の床材１０をフローリング仕上の下地材等として使用する場合には、上述のように木質繊維板１２の上表面側にマイクロカプセル１４を配設すれば床材１０の完成となる。しかしながら、本実施形態の床材１０は「畳」であるため、マイクロカプセル１４が配設された木質繊維板１２の上表面側に、クッション材１６及び畳表１８Ａがこの順で載置される。 When the flooring 10 of the present invention is used as a flooring finishing base material or the like, the flooring 10 is completed if the microcapsules 14 are disposed on the upper surface side of the wood fiber board 12 as described above. However, since the flooring 10 of the present embodiment is “tatami”, the cushion material 16 and the tatami surface 18A are placed in this order on the upper surface side of the wood fiber board 12 on which the microcapsules 14 are disposed.
クッション材１６は、床材１０である畳に更なるクッション性を付与すると共に、畳床の上表面を保護するため、必要に応じて配設されるシート状の部材である。このクッション材１６として、バルキー且つ柔軟で通気性を有するニードルパンチ不織布やサーマルボンド不織布などの不織布が好適に用いられる。 The cushion material 16 is a sheet-like member that is disposed as necessary to provide further cushioning to the tatami mat that is the floor material 10 and to protect the upper surface of the tatami floor. As the cushion material 16, a nonwoven fabric such as a needle punch nonwoven fabric or a thermal bond nonwoven fabric that is bulky, flexible, and breathable is preferably used.
畳表１８Ａは、「通気性を有する表装材１８」の代表的なもので、イ草や紙を撚った筒状抄繊糸を編織して得られる、畳の表装となるシート状の部材である。図示実施形態では、この畳表１８Ａの外縁が、木質繊維板１２の側面へ沿うように折り曲げられ、且つ、その先端が木質繊維板１２の下表面にてステープラーなどの固定具で固定される。
なお、図示実施形態では、上記の状態で畳を完成させているが、畳の外縁部に畳縁を取り付けるようにしてもよいし、畳床となる木質繊維板１２の下表面側に防滑シートなどを貼着してもよい。
また、図示実施形態では、木質繊維板１２一層で畳床が形成される場合を示しているが、木質繊維板１２を複数積層するようにしてもよいし、その複数層の木質繊維板１２の間にポリスチレンフォームなどの異種板材を積層するようにしてもよい。これらの場合、少なくとも最上層の木質繊維板１２の上表面側にマイクロカプセル１４が配設されていれば足りる。
The tatami surface 18A is a typical “breathable surface material 18”, and is a sheet-like member that becomes a tatami surface material obtained by weaving cylindrical fiber yarn twisted with grass or paper. is there. In the illustrated embodiment, the outer edge of the tatami table 18A is bent along the side surface of the wood fiber board 12, and the tip thereof is fixed on the lower surface of the wood fiber board 12 with a fixing tool such as a stapler.
In the illustrated embodiment, the tatami mat is completed in the above-described state, but a tatami rim may be attached to the outer edge of the tatami mat, or the anti-slip sheet may be provided on the lower surface side of the wood fiber board 12 serving as a tatami floor. Etc. may be attached.
In the illustrated embodiment, the tatami floor is formed by one layer of the wood fiber boards 12, but a plurality of the wood fiber boards 12 may be laminated, or the wood fiber boards 12 of the plurality of layers may be laminated. Different plate materials such as polystyrene foam may be laminated between them. In these cases, it is sufficient that the microcapsules 14 are disposed at least on the upper surface side of the wood fiber board 12 of the uppermost layer.
さらに、図示実施形態では、木質繊維板１２の側面から下表面に亘って、畳表１８Ａ以外にそれらを被覆するものはないが、木質繊維板１２の側面から下表面に亘る全体を金属箔や樹脂フィルムなどの不透気性或いは難透気性のシート（図示せず）で被覆するようにしてもよい。そうすることで、マイクロカプセル１４が破裂して放出される機能性材料が木質繊維板１２の側面や下面側から流出するのを低減させることができる。なお、木質繊維板１２の側面から下表面に亘る全体において若干の通気性が必要となる場合には、難透気性のシートとしてデュポン社製のタイベック(登録商標)に代表されるフラッシュスパン不織布を用いるのが特に好適である。 Further, in the illustrated embodiment, there is nothing to cover them other than the tatami surface 18A from the side surface of the wood fiber board 12 to the lower surface, but the whole from the side surface of the wood fiber board 12 to the lower surface is made of metal foil or resin. You may make it coat | cover with air-impermeable or hardly air-permeable sheets (not shown), such as a film. By doing so, it can reduce that the functional material discharged by bursting the microcapsule 14 flows out from the side surface or the lower surface side of the wood fiber board 12. In addition, when a slight air permeability is required in the whole from the side surface to the lower surface of the wood fiber board 12, a flash spun nonwoven cloth represented by Tyvek (registered trademark) manufactured by DuPont is used as a non-air-permeable sheet. It is particularly preferred to use it.
本実施形態の床材１０によれば、マイクロカプセル１４が配設された木質繊維板１２の上表面が畳表１８Ａで被覆されているので、床材１０である畳を踏み歩いた際、マイクロカプセル１４が破裂して内部の機能性材料が放出されると、即座に畳表１８Ａへと吸収される。このため、放出された機能性材料が足に付着して汚れるのを防止できると共に、畳表１８Ａを経由することによって機能性材料をより長い期間徐放させることができるようになる。 According to the flooring 10 of the present embodiment, the upper surface of the wood fiber board 12 on which the microcapsules 14 are disposed is covered with the tatami surface 18A. When 14 bursts and the functional material inside is released, it is immediately absorbed into the tatami mat 18A. For this reason, it is possible to prevent the released functional material from adhering to the foot and get dirty, and the functional material can be gradually released through the tatami surface 18A for a longer period of time.
また、本実施形態の床材１０によれば、床材１０のマトリックスとなる木質繊維板１２から放散される臭気を長期間継続して低減或いは抑制できることに止まらず、木質繊維板１２に付与する機能性材料の効果を長期間効率的に発揮させることができるが、発明者等は、以下の実験によってその効果を確認した。 Moreover, according to the flooring 10 of the present embodiment, the odor emitted from the wood fiberboard 12 serving as a matrix of the flooring 10 can be continuously reduced or suppressed for a long period of time, and is given to the wood fiberboard 12. Although the effect of the functional material can be exhibited efficiently for a long period of time, the inventors confirmed the effect by the following experiment.
［実験方法］
ヒノキから抽出した精油を芯物質とし、壁材として尿素系樹脂を使用した、平均粒径(レーザー回折・散乱法)３００μｍのマイクロカプセルを準備し、このマイクロカプセルを固形分４０重量％となるように水分散させて分散液を得た。この分散液をインシュレーションボードの表面に塗布量が１５ｇ／ｍ2となるようスプレーで塗布した後、室温で風乾させた。
分散液が乾燥してマイクロカプセルがその上表面側に配設されたインシュレーションボードの上表面に、クッション材として目付１５０ｇ／ｍ2のポリエステル・サーマルボンド不織布を載置すると共に、インシュレーションボードの側面から下表面に亘る全体を厚さ２５μｍのアルミ箔で二重に被覆した。
そして、インシュレーションボードの上表面に、筒状抄繊糸を編織して形成された大建工業（株）製の畳表（品番：清流０１銀白色）を載置し、その畳表の端部をインシュレーションボードの下表面側に巻き込み、ステープル止めして、実験用の畳を完成させた。
[experimental method]
Prepare microcapsules with an average particle size (laser diffraction / scattering method) of 300 μm using essential oil extracted from cypress as a core substance and urea resin as a wall material. The microcapsules have a solid content of 40% by weight. To obtain a dispersion. This dispersion was applied to the surface of the insulation board by spraying so that the amount applied was 15 g / m 2 and then air-dried at room temperature.
A polyester thermal bond nonwoven fabric having a basis weight of 150 g / m 2 is placed as a cushioning material on the upper surface of the insulation board on which the dispersion is dried and the microcapsules are arranged on the upper surface side. The entire surface from the side surface to the lower surface was covered with an aluminum foil having a thickness of 25 μm.
And on the upper surface of the insulation board, a tatami mat (product number: clear stream 01 silver white) made by Daiken Kogyo Co., Ltd. formed by weaving cylindrical fiber yarn is placed, and the end of the tatami mat is placed The tatami mat for the experiment was completed by winding on the lower surface side of the insulation board and stapling.
この畳の１５ｃｍ四方の所定部分について、畳表の上から軽く叩くことでヒノキの芳香が発散されることを確認した後、解放空間で放置したところ、約１週間は明確なヒノキの芳香が維持され、インシュレーションボードからの臭気がマスキングされていた。
また、上記状態で、ヒノキの芳香が微弱となる１カ月毎に、約５００回の足踏み圧縮を加えたところ、芳香の強さは毎回回復し、３カ月を超えても圧縮を加えればヒノキの芳香が漂ってくる。つまり、依然としてインシュレーションボードに付与した機能性材料の効果を発揮させることができる点を確認できた。
After confirming that the fragrance of cypress is emitted by tapping the 15cm square of this tatami mat from the top of the tatami surface, the cypress fragrance is maintained for about a week when left in an open space. The odor from the insulation board was masked.
In the above state, about 500 times of foot compression is applied every month when the fragrance of cypress becomes weak, and the strength of the fragrance is restored every time. The fragrance drifts. That is, it was confirmed that the effect of the functional material applied to the insulation board can still be exhibited.
一方、ヒノキから抽出した精油を、マイクロカプセルに封入しないでインシュレーションボードの表面に直接塗布し、それ以外は同様に作製した実験用の畳では、１週間以内にヒノキの芳香が焼失した後、足踏み圧縮を行っても芳香が回復することはなかった。 On the other hand, the essential oil extracted from cypress is applied directly to the surface of the insulation board without enclosing it in a microcapsule, and otherwise, in the experimental tatami mat produced in the same manner, after the aroma of cypress burned out within one week, The fragrance did not recover even after the foot compression.
