本発明は減臭効果を有する建築物修繕工事用メッシュシートに関する。詳しく述べると、マンション、公団住宅、ビル、公共施設、店舗、住宅などの建造物のコンクリート躯体ひび割れ修繕、外壁タイル補修やタイル貼替工事、外壁塗装のケレン作業や塗装工事（スプレー塗装の飛散防止）、ルーフィングシート張替工事、共有通路・階段のビニルタイル床材張替工事など、複数の修繕を伴う大規模修繕工事の現場張囲に使用し、特に塗装や接着剤を使用するタイル貼替、ビニル床材やルーフィングシートの張替接着工事、ベランダ・バルコニー・共有通路排水部のウレタン塗装に伴う、化学物質臭や有機溶剤臭、さらに工事現場近隣に漂う臭気などを減少させる減臭効果、及び発生臭気の拡散防止効果を有し、しかも減臭効果が修繕工事期間中、シート張囲のまま太陽光に晒すだけで良好に持続可能な建築物修繕工事用メッシュシートに関する。 The present invention relates to a mesh sheet for building repair work having a deodorizing effect. In detail, concrete frame crack repair of buildings such as condominiums, public housing, buildings, public facilities, stores, houses, exterior wall tile repair and tile replacement work, outer wall paint cleansing and painting work (prevention of spray paint scattering) ), Replacement of roofing sheets, replacement of vinyl tile floor materials for common passages and stairs, etc., for site extension of large-scale repair work involving multiple repairs, especially tile replacement using paint or adhesive , Deodorizing effect to reduce chemical odor, organic solvent odor, odor drifting in the vicinity of construction site, etc. accompanying urethane coating of vinyl flooring and roofing sheet, urethane painting of veranda, balcony, common passage drainage part, In addition, it has an effect of preventing the diffusion of generated odors and has a deodorizing effect that can be maintained well by simply exposing it to sunlight while the seat is stretched during the repair period. For Construction for the mesh sheet.
マンションでは住民の快適な生活と、マンションの資産価値を維持するために、１０〜１２年を目安に大規模修繕工事を行い、老朽化した建築部材の交換や外装の化粧直しを定期的に行っている。最近では築３０年を越えるマンションの数が軒並み増加しており、大規模修繕工事の需要が急増の傾向にある。特に今後は高齢化社会への移行に伴い、マンション永住希望者の増加が予測されることで大規模修繕工事に対する意識も日増しに高くなっている。 In condominiums, in order to maintain the residents' comfortable life and the asset value of the apartments, large-scale repair works are carried out in 10 to 12 years as a guideline, replacement of aging building materials and refurbishment of exteriors are performed regularly. Yes. Recently, the number of condominiums that are over 30 years old is increasing, and the demand for large-scale repair works is on the rise. In particular, with the shift to an aging society in the future, an increase in the number of people who want to live in condominiums is expected to increase the awareness of large-scale repair works.
このようなマンションの大規模修繕工事の需要増加に伴い、マンション全体を張囲する養生メッシュシートの需要も増加している。この張囲は工事現場の目隠しと同時に、通行人や近隣に対し、工事で使用する修繕資材や工具などの落下による傷害事故の防止、スプレー塗料の飛散防止などの目的で仮設されるものである。養生メッシュシートとしては、ポリエステル繊維の粗目織物を軟質塩化ビニル樹脂で防炎加工したものが主に使用されている。マンションの修繕工事張囲に養生メッシュシートを使用することで、修繕作業空間として適度な通気性と採光性が確保される。しかし、工事期間中もマンション生活を続ける住民にとっては、窓外の視界全域が養生メッシュシートで奪われる圧迫感、昼間でも薄暗いなど、ストレスとなり、さらに修繕工事に伴う騒音や臭気がストレスを増長させることがあった。 Along with the increase in demand for such large-scale repair work for condominiums, there is also an increasing demand for curing mesh sheets that surround the entire apartment. At the same time as blindfolding at the construction site, this extension is temporarily installed for the purpose of preventing accidents caused by falling repair materials and tools used in the construction, and preventing spray paint from scattering, for passersby and neighbors. . As the curing mesh sheet, a polyester fiber coarse fabric woven with a soft vinyl chloride resin for flameproofing is mainly used. By using a curing mesh sheet for the repair work of the apartment, moderate ventilation and lighting are secured as a repair work space. However, for residents who continue living in condominiums during the construction period, the entire field of view outside the window is stressed by being taken away by the curing mesh sheet, and it is dim even in the daytime, and stress and noise and odor associated with repair work increase the stress. There was a thing.
マンションの修繕工事には、コンクリート躯体ひび割れ修繕、外壁タイル補修やタイル貼替工事、外壁塗装のケレン作業や塗装工事（スプレー塗装の飛散防止）、屋根防水工事（アスファルト敷設・ウレタン塗工・ルーフィングシート貼付）、共有通路・階段ビニルタイル床材の張替工事、ベランダ・バルコニー・共有通路排水部のウレタン塗装などがあり、これら工事に使用するシーリング材、コーキング材、接着剤、塗料、シンナー、アスファルトシート、ウレタンコート液、ルーフィングシート、ビニル床材などは個々独特の化学物質臭や有機溶剤臭を有している。 For repair work of condominiums, concrete frame crack repair, exterior wall tile repair and tile replacement work, exterior wall paint cleansing and painting work (prevention of spray paint scattering), roof waterproofing work (asphalt laying, urethane coating, roofing sheet) Affixed), common corridor / staircase vinyl tile flooring replacement work, urethane coating on veranda / balcony / common corridor drainage, etc. Sealing materials, caulking materials, adhesives, paints, thinner, asphalt used in these constructions Sheets, urethane coating liquids, roofing sheets, vinyl flooring, etc. each have a unique chemical odor or organic solvent odor.
マンションの塗装工事では特に住民や近隣に配慮してシンナーを含まないエマルジョン塗料を使用することで発生臭気を軽減している。しかし尚もエマルジョン樹脂に含む未反応モノマーや乳化剤などの化学物質臭（例えばアクリル臭、スチレン臭、エポキシ臭、酢酸臭、アンモニア臭など）が塗膜乾燥後にも微弱に長期間発散し続けるものがある。また外壁タイル補修に用いるエポキシ接着剤の臭気、共有通路や階段部に敷設するビニル床材の塩化ビニル樹脂臭や接着剤の溶剤臭（トルエン、メチルエチルケトン、酢酸ブチルなど）なども不快臭の原因となっている。これら複数の化学物質臭気が混在してマンション修繕工事の張囲内に滞留すると、住民の体質や体調によっては頭痛、発疹、食欲不振などの健康障害を引き起こしたり、あるいは近隣に拡散流延することで異臭トラブルを招くことがあった。 Odors are reduced by using emulsion paints that do not contain thinner, especially in the construction of condominiums in consideration of residents and the neighborhood. However, chemical substances odors such as unreacted monomers and emulsifiers contained in the emulsion resin (for example, acrylic odor, styrene odor, epoxy odor, acetic acid odor, ammonia odor, etc.) continue to diverge slightly and for a long time after the coating is dried. is there. Odor of epoxy adhesive used for repairing exterior wall tiles, vinyl chloride resin odor of vinyl flooring laid in common passages and staircases, and solvent odor of adhesive (toluene, methyl ethyl ketone, butyl acetate, etc.) also cause unpleasant odors It has become. If these multiple chemical odors coexist and stay in the condominium repair work, they may cause health problems such as headaches, rashes, and loss of appetite depending on the constitution and condition of the residents, or may spread and spread nearby. Occasion of nasty smell problems.
今までに吸着型やイオン中和型の消臭性物質を用いた家庭用消臭商品が数多く提案されているが、何れも時間の経過と共に臭気分子処理能力が飽和状態に陥り、消臭効果が激減するので、そのサイクルで新しい商品との交換が行われてきた。一方、電気装置を伴う商品による消臭は継続安定的な消臭を可能とするが、電池や電源を必要とする維持管理の不自由があった。このためマンション修繕工事用の建築養生メッシュシートとして、特にタイル貼替、ビニルタイル床材やルーフィングシートの張替接着工事に使用する修繕資材の臭気や、スプレー塗装に用いる塗料やシンナーなどの有機溶剤に起因する発生臭気を減少させる減臭効果と、発生臭気の拡散防止効果とを有し、しかもその効果が修繕工事期間内安定的に持続できるような建築物修繕工事用メッシュシートが切望されていた。 Many household deodorization products using adsorption-type or ion-neutralization-type deodorant substances have been proposed so far, but all of them have become saturated with odor molecular treatment capacity over time, and the deodorization effect Has been drastically reduced, so new products have been exchanged in that cycle. On the other hand, deodorization by products with electric devices enables continuous and stable deodorization, but there is a maintenance inconvenience that requires batteries and a power source. For this reason, as an architectural curing mesh sheet for repair work on condominiums, organic solvents such as odors of repair materials used for tile replacement, replacement of vinyl tile flooring and roofing sheets, paints and thinners used for spray coating, etc. There is a strong demand for a mesh sheet for building repair work that has a deodorizing effect that reduces the odor caused by odor and a diffusion prevention effect of the generated odor, and that the effect can be stably maintained throughout the repair work period. It was.

It has a deodorizing effect that reduces chemical odors and organic solvent odors in repair work materials, and also prevents diffusion of generated odors due to adhesive construction, urethane painting of verandas, balconies, and common passage drainage areas, and also has a deodorizing effect. However, during the repair work, the company intends to provide a mesh sheet for building repair work that can be maintained sustainably by simply exposing it to sunlight with the seat stretched.

本発明によると、修繕工事資材の化学物質臭や有機溶剤臭を減少させる減臭効果、及び発生臭気の拡散防止効果を有し、しかも減臭効果が修繕工事期間中、シート張囲のまま太陽光に晒すだけで良好に持続可能な建築物修繕工事用メッシュシートを得ることができるので、マンション、公団住宅、ビル、公共施設、店舗、住宅などの建造物の修繕工事現場に使用し、特に塗装や接着剤を使用するタイル貼替、ビニル床材やルーフィングシートの張替接着工事、ベランダ・バルコニー・共有通路排水部のウレタン塗装に伴う発生臭気を軽減することができ、さらに工事現場近隣に漂う臭気（排気ガス、調理臭、タバコ臭、ペット臭）の軽減効果にも有効である。 According to the present invention, it has a deodorizing effect that reduces chemical odors and organic solvent odors in repair work materials, and an effect of preventing the diffusion of generated odors. Since it is possible to obtain a mesh sheet for building repair work that can be sustained sustainably just by exposing it to light, it is used for repair work on buildings such as condominiums, public housing, buildings, public facilities, stores, and houses. Tile replacement using paint and adhesives, re-adhesion work for vinyl flooring and roofing sheets, and the odor generated by urethane coating on the drainage of verandas, balconies and common passages can be reduced. It is also effective in reducing floating odors (exhaust gas, cooking odor, tobacco odor, pet odor).
本発明の建築物修繕工事用メッシュシートは、経糸条及び緯糸条を要素とする平織物と、この平織物を被覆する軟質塩化ビニル樹脂層とで構成された経被覆糸条及び緯被覆糸条を配置密度２０〜３０本／２５．４ｍｍで含み、それによって充実率６５〜８０とする通気性複合体で、特に軟質塩化ビニル樹脂層に、軟質塩化ビニル樹脂層の３〜１０質量％相当量の臭気吸着粒子を含み、この臭気吸着粒子とは、白炭粒子と電気鉱石粒子からなる質量比３：１〜１：３の複合焼成物で主構成されるものである。 The mesh sheet for building repair work of the present invention is a warp-coated yarn and a weft-covered yarn composed of a plain fabric having warps and wefts as elements and a soft vinyl chloride resin layer covering the plain fabric. Is an air-permeable composite having an arrangement density of 20 to 30 pieces / 25.4 mm, and thereby a solidity ratio of 65 to 80, particularly in the soft vinyl chloride resin layer, corresponding to 3 to 10% by mass of the soft vinyl chloride resin layer. The odor adsorbing particles are mainly composed of a composite fired product having a mass ratio of 3: 1 to 1: 3 composed of white coal particles and electric ore particles .
本発明の建築物修繕工事用メッシュシートにおいて、軟質塩化ビニル樹脂層は、ペースト塩化ビニル樹脂組成物によるプラスチゾル中に平織物を浸漬し、平織物にプラスチゾルを含浸かつ被覆した後、熱風加熱によりペースト塩化ビニル樹脂組成物をゲル化させて被覆固化物としたもの、あるいはプラスチゾルを平織物の両面に塗工被覆した状態でゲル化被覆固化物としたものである。ペースト塩化ビニル樹脂組成物の組成（量）に特に限定は無いが主に、塩化ビニル樹脂、可塑剤、安定剤、充填剤、難燃剤、着色剤、紫外線吸収剤などの公知要素の組み合わせで構成され、この構成に臭気吸着粒子（白炭粒子／電気鉱石粒子）を必須要素とするものである。軟質塩化ビニル樹脂層の厚さは０．０５〜１．０ｍｍ、特に０．１〜０．３５ｍｍが好ましく、有機顔料や無機顔料により、ライトブルー、ライトグリーン、ライトグレー、ホワイト、ブラック、シルバーなど任意の着色が可能である。 In the mesh sheet for building repair work of the present invention, the soft vinyl chloride resin layer is formed by immersing a plain woven fabric in a plastisol made of a paste vinyl chloride resin composition, impregnating and covering the woven fabric with a plastisol, and then heating the paste by hot air heating. A vinyl chloride resin composition is gelled to obtain a coated solidified product, or a plastisol is applied to both sides of a plain woven fabric to form a gelated coated solidified product. The composition (amount) of the paste vinyl chloride resin composition is not particularly limited, but is mainly composed of a combination of known elements such as vinyl chloride resin, plasticizer, stabilizer, filler, flame retardant, colorant, and UV absorber. In this structure, odor adsorbing particles (white coal particles / electric ore particles) are essential elements. The thickness of the soft vinyl chloride resin layer is preferably 0.05 to 1.0 mm, particularly preferably 0.1 to 0.35 mm. Depending on the organic pigment or inorganic pigment, light blue, light green, light gray, white, black, silver, etc. Any coloration is possible.
また軟質塩化ビニル樹脂層には気泡痕を含み、この気泡痕の含有体積率が軟質塩化ビニル樹脂層の体積に対して５〜２５体積％であることで軟質塩化ビニル樹脂層の表面積が増大し、それによって表面に露出する臭気吸着粒子の総和面積が増大することでより減臭効果を向上させることができる。このような気泡痕の生成はプラスチゾルの機械攪拌による巻き込み空気の残留、または公知の化学発泡剤（熱分解気化型）の方法による。 The soft vinyl chloride resin layer contains bubble marks, and the volume ratio of the bubble marks is 5 to 25% by volume with respect to the volume of the soft vinyl chloride resin layer, thereby increasing the surface area of the soft vinyl chloride resin layer. As a result, the total area of the odor adsorbing particles exposed on the surface is increased, whereby the deodorizing effect can be further improved. The generation of such bubble marks is caused by the residual of entrained air by mechanical stirring of plastisol or the method of a known chemical foaming agent (thermal decomposition vaporization type).
軟質塩化ビニル樹脂層には、白炭粒子／電気鉱石粒子の組み合わせからなる臭気吸着粒子を、軟質塩化ビニル樹脂層の質量に対して３〜１０質量％含み、白炭粒子と電気鉱石粒子との配合比が、質量比で３：１〜１：３を構成する複合焼成物で主構成されることが好ましい。白炭粒子は多数の微細孔を有し、その微細孔に臭気分子（化学物質）を吸着する活性炭である。一方、電気鉱石粒子（トルマリン）は太陽光の紫外線及び熱線を受けて微弱電荷を発生することで臭気分子（化学物質）を吸着する機構、あるいはマイナスイオンで臭気分子を中和や還元すると同時に、この微弱電流が白炭粒子の吸着効果を繰り返し再生させる。従って白炭粒子／電気鉱石粒子の特定比による組み合わせを有し、これに太陽光を浴びせ続ける限り、本発明のメッシュシートの減臭効果は吸着飽和状態に陥ること無く、吸着効果が再生されるので安定的して減臭効果が継続される。従って、マンションの修繕工事期間中、本発明のメッシュシートを張囲しておくことで、溶剤臭など臭気分子を吸着し、吸着効果が飽和しても、太陽光の紫外線や熱線を受けて元の状態に還元されることで溶剤臭など、化学物質臭を安定して低減することを可能とする。軟質塩化ビニル樹脂層の質量に対する臭気吸着粒子の含有量が３質量％未満だと十分な減臭効果を得ることができないことがある。また白炭粒子と電気鉱石粒子との質量比３：１〜１：３のバランスを外れると太陽光に晒した時の減臭効果の再生持続性が良好に発現されないことがある。
The soft vinyl chloride resin layer contains 3 to 10% by mass of odor adsorbing particles composed of a combination of white coal particles / electric ore particles with respect to the mass of the soft vinyl chloride resin layer, and the mixing ratio of the white coal particles and the electric ore particles. However, it is preferable that it is mainly comprised by the composite baking products which comprise 3: 1 to 1: 3 by mass ratio . White charcoal particles are activated carbon that has a large number of fine pores and adsorbs odor molecules (chemical substances) in the fine pores. On the other hand, electric ore particles (tourmaline) receive weak ultraviolet rays and heat rays from sunlight to generate a weak charge, or adsorb odor molecules (chemical substances), or neutralize and reduce odor molecules with negative ions, This weak current repeatedly regenerates the adsorption effect of the white coal particles. Therefore, as long as it has a combination of white coal particles / electric ore particles and continues to be exposed to sunlight, the deodorizing effect of the mesh sheet of the present invention is regenerated without falling into the adsorption saturation state. Stable and deodorizing effect is continued. Therefore, by covering the mesh sheet of the present invention during the repair work of the apartment, it absorbs odor molecules such as solvent odor, and even if the adsorption effect is saturated, it receives the ultraviolet rays and heat rays of sunlight. It is possible to stably reduce chemical odors such as solvent odors by being reduced to the above state. If the content of the odor adsorbing particles with respect to the mass of the soft vinyl chloride resin layer is less than 3% by mass, a sufficient deodorizing effect may not be obtained. Further, if the balance of the white coal particles and the electric ore particles is out of the balance of 3: 1 to 1: 3, the regeneration susceptibility of the deodorizing effect when exposed to sunlight may not be expressed well.
白炭粒子とは、ウバメガシ、アオガシ、ナラなどを原料として１０００〜１３００℃で炭化させ、これらの赤熱状態に素灰を掛け急冷して出来た光沢のある硬質黒炭を、粒子径０．１μｍ〜３０μｍに粉砕した活性炭粒子、あるいは竹（孟宗竹）を８００〜１０００℃で炭化させ、これらの赤熱状態に素灰を掛け急冷して出来た光沢のある硬質黒炭を、粒子径０．１μｍ〜３０μｍに粉砕した活性炭粒子である。１０００℃を超える温度で炭化された竹炭は微細孔が収縮して化学物質（臭気物質）の吸着性能が低下することがある。白炭粒子は実質的には黒色であるが、素灰を掛けた外観が白であることから、素灰を掛けない黒炭と区別して「白炭（しろずみ）」という。白炭粒子は素灰を含んだまま粉砕し、その状態で使用することによって、活性炭粒子の外観色が灰色であるものも本発明では使用できる。白炭の例として備長炭、ナラ白炭、カシ白炭、白竹炭が挙げられ、特に本発明においては白竹炭（竹の備長炭）による活性炭粒子が好ましい。 The white charcoal particles are carbonized at 1000 to 1300 ° C. using ubatmegashi, blue oak, oak, etc. as raw materials, and these hard red coals are made by ashing them in a red hot state and rapidly cooling, and the particle diameter is 0.1 μm to 30 μm.

Bamboo charcoal carbonized at a temperature exceeding 1000 ° C. may shrink the pores and reduce the adsorption performance of chemical substances (odor substances). The white charcoal particles are substantially black, but the appearance of the white ash is white, so it is called “white charcoal” to distinguish it from the black charcoal without the black ash. The white charcoal particles can be used in the present invention in which the activated carbon particles are gray in color by pulverizing them while containing the raw ash and using them in that state. Examples of white charcoal include bincho charcoal, oak white charcoal, oak white charcoal, and white bamboo charcoal.
