Description

本発明は、建築物等に用いられる塗材に関し、詳しくは、大谷石粉を主成分とする機能性塗材に関するものである。   The present invention relates to a coating material used for buildings and the like, and more particularly to a functional coating material mainly composed of Otani stone powder.

我が国の天然資源は極めて少なく、持続可能な発展を続けていくためには、従来の「大量生産・大量消費・大量廃棄」型の経済社会から脱却し、環境への負荷が少ない「廃棄物の発生抑制・再使用・再資源化」の所謂3R(Reduce、Reuse、
Recycle)の取り組みを充実させて、循環型社会を確立していくことが必要である。そこで、係る循環型社会の形成を推進する基本的な枠組みとして「循環型社会形成推進基本法」が制定され、特に建設廃棄物は全体の約2割を占めることもあり、「建設工事に係る資材の再資源化等に関する法律(略称:建設リサイクル法)」も施行されている。
Japan's natural resources are extremely few, and in order to continue sustainable development, we will move away from the conventional “mass production, mass consumption, mass disposal” economic society, So-called 3R (Reduce, Reuse, Reducing, Reusing, Recycling)
It is necessary to establish a recycling-oriented society by enhancing Recycle). Therefore, the Basic Law for the Promotion of a Recycling Society was established as a basic framework for promoting the formation of a recycling society. In particular, construction waste may account for about 20% of the total. The Law Concerning Recycling of Materials (abbreviation: Construction Recycling Law) is also being enforced.

ここで、天然資源のひとつに大谷石(おおやいし)がある。大谷石は、珪酸・第二酸化鉄・酸化アルミニウム・酸化マンガン・石灰・酸化マグネシウム・カリウム・ナトリウムなどを成分とする緑色の軽石凝灰岩の一種で、栃木県宇都宮市北西部の大谷町付近一帯で採掘される石材である。多孔質で火熱に強く、1000℃以上でも安定し、他の石材に比べて軟らかく、採掘や加工がしやすいことから、古くから外壁や土蔵などの建材として使用されてきた。また、大谷石に含まれるゼオライト成分は、多量のマイナスイオンと強い遠赤外線を放出し、癒し効果や熟成効果を発揮するとともに、その多孔質構造により、音響効果、脱臭効果及びガスや水を吸着する特性もあり、シックハウス症候群の防止や消臭に資する石材である。   Here, one of the natural resources is Oyaishi. Otani stone is a type of green pumice tuff composed of silicic acid, ferric oxide, aluminum oxide, manganese oxide, lime, magnesium oxide, potassium, sodium, etc., mined in the area near Otani Town in the northwestern part of Utsunomiya City, Tochigi Prefecture. Stone material. It has been used as a building material for outer walls and storehouses for a long time because it is porous, strong against heat, stable at temperatures above 1000 ° C, softer than other stones, and easy to mine and process. In addition, the zeolite component contained in Otani stone releases a large amount of negative ions and strong far-infrared rays, exhibits healing and aging effects, and adsorbs acoustic and deodorizing effects and gas and water due to its porous structure. It is a stone that contributes to prevention and deodorization of sick house syndrome.

このような機能性を有する大谷石であるが、近年では採掘量も減り、大谷石の希少価値が高まるとともに、大谷石の有効利用が求められるところである。   Although it is Oya stone having such functionality, in recent years, the amount of mining has been reduced, the rare value of Oya stone is increased, and effective use of Oya stone is required.

そこで、従来より種々の技術が提案されている。例えば、大谷石の特性を利用した技術として、原料の大谷石を細かく砕く粉砕工程と、その粉砕した大谷石の1.7mm以上及び0.3mm以下の粒径の粒子を除去して0.3〜1.7mmの粒子を得る粒子選別工程と、その選別で得られた粒子を含水率6%以下に乾燥させる乾燥工程と、その乾燥させた大谷石の粒子100重量部に対して、粘度150〜300mPa・s(5%水溶液、20°C)のアクリル酸エステル・メタクリル酸エステル共重合体樹脂を含水率6%以下に水分調節してなる粉末バインダーを4〜7重量部混合するバインダー混合工程と、から成る大谷石を用いた壁面鏝塗り材の製造方法及び、該製造方法で製造した大谷石を用いた壁面鏝塗り材がある(特許文献1参照)。しかし、係る技術は、前記大谷石の機能性を阻害しないように樹脂の使用量を少なくして、粒子表面を露出させて有害ガスの吸着性等を確保しているため、付着力や強度を高めることができず、下地の変化に伴う追従性や割れやすいという問題がある。また、耐水性も低くなってしまうという問題もある。   Therefore, various techniques have been conventionally proposed. For example, as a technique using the characteristics of Oya stone, a pulverization step for finely crushing raw Oya stone, and particles having a particle diameter of 1.7 mm or more and 0.3 mm or less of the pulverized Oya stone are removed to obtain 0.3 A particle sorting step for obtaining particles of ˜1.7 mm, a drying step for drying the particles obtained by the sorting to a moisture content of 6% or less, and a viscosity of 150 parts by weight for 100 parts by weight of the dried Oyaishi particles. Binder mixing step of mixing 4 to 7 parts by weight of a powder binder obtained by adjusting the water content of an acrylic ester / methacrylic ester copolymer resin of ˜300 mPa · s (5% aqueous solution, 20 ° C.) to a moisture content of 6% or less And a method for producing a wall surface coating material using Otani stone, and a wall surface coating material using Otani stone produced by the production method (see Patent Document 1). However, this technology reduces the amount of resin used so as not to impede the functionality of the Oya stone, and exposes the particle surface to ensure adsorbability of harmful gases. There is a problem in that it cannot be increased, and it is easy to follow and change with the change of the groundwork. There is also a problem that water resistance is lowered.

さらにまた、石材等の天然素材の質感を活かした装飾的機能を発揮させるために、合成樹脂エマルション等に天然石材等を配合した塗材に関する技術も多数提案されている。例えば、御影石等の天然石の模様を形成することができる塗材として、無色透明な被膜を形成する結合材と着色骨材と透明骨材とを組み合わせた塗材がある(特許文献2参照)。しかし、係る技術は、特定の石材が有する機能性に着目して限定するものではなく、天然石特有の深みのような美観を創出させることを目的としているものであり、ゼオライトを添加しておらず、有害ガスの吸着性や消臭といった機能性が低いという問題がある。   Furthermore, in order to exhibit a decorative function that takes advantage of the texture of natural materials such as stone materials, many techniques relating to coating materials in which natural stone materials are blended with synthetic resin emulsions have been proposed. For example, as a coating material that can form a natural stone pattern such as granite, there is a coating material that combines a binder that forms a colorless and transparent film, a colored aggregate, and a transparent aggregate (see Patent Document 2). However, this technology is not limited by focusing on the functionality of a specific stone material, but is intended to create an aesthetics such as the depth unique to natural stone, and does not contain zeolite. There is a problem that functionality such as adsorptivity and deodorization of harmful gases is low.

またさらに、アクリル酸アルキルエステルに由来するアクリル樹脂、及び環状シロキサン化合物に由来するシリコーン樹脂が99:1〜30:70の重量比率でエマルション粒子内に混在する合成樹脂エマルション(A)、自然石の粉砕物、陶磁器の粉砕物、及び着色骨材から選ばれる少なくとも一種の骨材(B)を必須成分とし、前記合成樹脂エマルション(A)の固形分100重量部に対し、前記骨材(B)を100〜2000重量部含むことを特徴とする水性塗材の技術も提案されている(特許文献3参照)。しかしながら、係る発明も、天然ゼオライト鉱石粉を添加しておらず、前記同様に、有害ガスの吸着性や消臭機能が低いという問題がある。   Furthermore, the synthetic resin emulsion (A) in which the acrylic resin derived from the alkyl acrylate ester and the silicone resin derived from the cyclic siloxane compound are mixed in the emulsion particles at a weight ratio of 99: 1 to 30:70, At least one kind of aggregate (B) selected from pulverized product, ceramic pulverized product, and colored aggregate is an essential component, and the aggregate (B) with respect to 100 parts by weight of the solid content of the synthetic resin emulsion (A). A water-based coating technique characterized by containing 100 to 2000 parts by weight of water is also proposed (see Patent Document 3). However, this invention also has a problem in that no natural zeolite ore powder is added, and the adsorbability and deodorizing function of harmful gases are low as described above.

そして、天然大谷石のリサイクル壁材は、過去、何度となく左官壁材として利用しようと試みた企業が複数あったものの、壁材として使用する為に必要な耐久性に問題があり、壁材として使用すると、壁塗りした所と躯体壁との間に剥離現象がおき、亀裂や落下などの問題が生じるため長期使用には難があった。
その為、現在、実用化されているケースは、出願人の知る所では皆無である。
And there are several companies that have tried to use natural Oya stone recycled wall materials as plastering wall materials several times in the past, but there are problems with the durability required to use them as wall materials. When used as a material, there is a peeling phenomenon between the wall coating and the housing wall, which causes problems such as cracking and dropping, which makes it difficult to use for a long time.
For this reason, there are no cases where the applicant knows at present.

そこで、本発明は、このような問題点に鑑みなされたものであり、剥離や亀裂などを起こさず、長期にわたる使用に耐えられ、尚且つ、大谷石本来の特性を活かした機能性塗材を提供することを目的とするものである。   Therefore, the present invention has been made in view of such problems, a functional coating material that can withstand long-term use without causing peeling or cracking and that takes advantage of the original characteristics of Oyaishi. It is intended to provide.

前記目的を達成するため、請求項1の発明は、大谷石粉100重量部に対して、ゼオライト22.5〜27.5重量部、角また粉5.7〜6.6重量部、硅砂7号45〜55重量部、ミネゼオン(登録商標)45〜55重量部、アクリルエマルションを固形分で40〜45重量部含有する手段を採用した。In order to achieve the above object, the invention of claim 1 is based on 100 parts by weight of Otani stone powder, 22.5 to 27.5 parts by weight of zeolite, 5.7 to 6.6 parts by weight of corn or powder, and No. 7 cinnabar sand. 45 to 55 parts by weight, Minezeon (registered trademark) 45 to 55 parts by weight, a means containing 40 to 45 parts by weight of an acrylic emulsion in solid content was employed.

また、請求項2の発明は、大谷石粉100重量部に対して、鹿沼土粉40.5〜49.5重量部、ゼオライト22.5〜27.5重量部、角また粉5〜7重量部、硅砂7号45〜55重量部、ミネゼオン(登録商標)45〜55重量部、アクリルエマルションを固形分で40〜45重量部含有する手段を採用した。The invention of claim 2 is based on 100 parts by weight of Otani stone powder, 40.5 to 49.5 parts by weight of Kanuma soil powder, 22.5 to 27.5 parts by weight of zeolite, and 5 to 7 parts by weight of horn or powder. , Chin sand No. 7 45-55 parts by weight, Minezeon (registered trademark) 45-55 parts by weight, and means containing 40-45 parts by weight of an acrylic emulsion in solid content.

また、請求項3の発明は、前記大谷石粉、前記ゼオライト、及び前記ミネゼオン(登録商 標)の粒径が其々0.2mm以下であることを特徴とする前記記載の大谷石粉含有塗材とする手段を採用した。The invention of claim 3, wherein Oya powder, and the zeolite, and Oya powder-containing coating material of the, wherein the particle size of Minezeon (registered trademark) is equal to or less than其s 0.2mm Adopted the means to do.

本発明に係る大谷石粉含有塗材によれば、調湿機能の優れた塗材を提供できるといった優れた効果を奏する。   According to the coating material containing Otani stone powder according to the present invention, there is an excellent effect that a coating material having an excellent humidity control function can be provided.

また、大谷石粉は大量のマイナスイオンを発生するので、細胞の活性化や免疫強化、自律神経の調整、精神安定、空気の清浄化などさまざまな有効作用がある。したがって、例えば、本発明に係る大谷石粉含有塗材を内壁に用いれば、優れたリラックス空間を創ることができるといった効果を発揮し得る。   In addition, Otani stone powder generates a large amount of negative ions, and thus has various effective actions such as cell activation and immune enhancement, autonomic nerve adjustment, mental stability, and air purification. Therefore, for example, if the Oya stone powder-containing coating material according to the present invention is used for the inner wall, an effect that an excellent relaxing space can be created can be exhibited.

また、大谷石はミネラルを含むゼオライト成分を有しているため、電磁波の一種である遠赤外線を放出し、それにより食品の中の水分子が共鳴振動を起こすことで、クラスター破壊による活性化が図られ、腐敗の進行やカビの発生を抑制し、鮮度を保ちながら熟成を進ませることができ、日持ちも良くなる。したがって、例えば、本発明に係る大谷石粉含有塗材を用いた空間で生ハムを熟成されれば、人為的に作られた施設での熟成に比べ、肉の旨味成分である遊離グルタミン酸を多くすることができるといった優れた効果を奏する。   In addition, because Otani stone has a mineral-containing zeolite component, it emits far-infrared rays, which are a type of electromagnetic wave, which causes resonance vibration of water molecules in food, which activates by cluster destruction. As a result, it is possible to suppress the progress of decay and the occurrence of mold, and to keep aging while maintaining freshness. Therefore, for example, if ham is aged in a space using the coating material containing Otani stone powder according to the present invention, the amount of free glutamic acid, which is an umami component of meat, is increased compared to aging in an artificially made facility. There is an excellent effect of being able to.

また、本発明に係る大谷石粉含有塗材によれば、ビルの内装やマンション、個別住宅の内装などを塗り壁材とする事で、壁を塗るだけで大谷石本体施工と同じよぅな効果を発揮させる事ができるという優れた効果を奏する。   In addition, according to the coating material containing Otani stone powder according to the present invention, the interior effect of a building, an apartment, an interior of an individual house, etc. is used as a coating wall material, so that the same effect as the construction of the Otani stone main body can be achieved just by painting the wall. There is an excellent effect that it can be demonstrated.

また、本発明に係る大谷石粉含有塗材によれば、大谷石本体の施工より施工が容易になるとともに、大谷石本体直接施工と比して安価な価格で提供できるという優れた効果を奏する。   In addition, according to the Oya stone powder-containing coating material according to the present invention, the construction is easier than the construction of the Oya stone main body, and there is an excellent effect that it can be provided at a lower price than the direct construction of the Oya stone main body.

また、本発明に係る大谷石粉含有塗材によれば、廃棄物の利用を主にすることができる為、大谷石の枯渇や環境に優しいといった優れた効果を奏する。   Moreover, according to the Oya stone powder containing coating material which concerns on this invention, since the utilization of a waste can be made mainly, there exist the outstanding effects, such as exhaustion of Oya stone, and an environment friendly.

また、本発明に係る大谷石粉含有塗材によれば、天然素材を使うので、人体に優しい内装材を提供できるといった優れた効果を奏する。   Moreover, according to the Oya stone powder containing coating material which concerns on this invention, since a natural material is used, there exists the outstanding effect that an interior material gentle to a human body can be provided.

また、大谷石はコンクリートやガラスに比べ高い吸音率を有しており、その平均吸音率を測定することにより求められる残響時間から、その環境に適した音楽を分類すれば、暖かみのある風合いを活かしたうえで、空間形状や設計との連係により演奏や音楽の種類に合った、優れた音響空間を演出することも可能になるという優れた効果を奏する。   Otani stone has a higher sound absorption rate than concrete and glass, and if the music suitable for the environment is classified based on the reverberation time required by measuring the average sound absorption rate, a warm texture can be obtained. It is possible to produce an excellent acoustic space that suits the type of performance and music by utilizing the space shape and design.

つぎに、本発明に係る大谷石粉含有塗材について、財団法人建材試験センター(埼玉県草加市稲荷5町目21番地20号)にて、品質性能試験を行っているので、以下に示す。   Next, the Oya stone powder-containing coating material according to the present invention is subjected to a quality performance test at the Building Materials Testing Center (No. 21, No. 21, Inari, 5-cho, Soka City, Saitama Prefecture).

大谷石粉及びゼオライトの粒径は其々0.3mm以下とし、望ましくは0.2mm以下とする。係る大谷石粉を100重量部とした場合を基準にして、他の混合材量の含有量を定める。ゼオライト自体は元々大谷石に含まれているが、マイナスイオンや遠赤外線の発生量を高めるとともに、吸着効果も向上させるために、大谷石粉100重量部に対してゼオライトを22.5〜27.5重量部混入することが本発明では必要である。係るゼオライトは特に限定されるものではなく、一般的な沸石を粉砕したものでよい。実験に使用したゼオライトの成分を参考までに示すと、水分(N:4.18%)、pH(乾物相当量1:10、21℃:7.2)、以下、乾物換算値で、リン酸全量(P:0.03%)、加里全量(KO:2.12%)、石灰全量(CaO:2.06%)、苦土全量(MgO:0.55%)、ケイ酸全量(SiO:71.66%)、酸化鉄(Fe:1.66%)、酸化アルミニウム(Al:11.61%)、酸化ナトリウム(NaO:2.22%)、陽イオン交換量(166meq/乾物100g)であった。大谷石粉及びゼオライトの粒径はできだけ揃えることが望ましく、一般的なボールミル(チューブミル)等の粉砕機で得ることが考えられる。 The particle diameters of Otani stone powder and zeolite are each 0.3 mm or less, preferably 0.2 mm or less. Based on the case where the Otani stone powder is 100 parts by weight, the content of other mixed materials is determined. Zeolite itself is originally contained in Otani stone, but in order to increase the amount of negative ions and far infrared rays generated and to improve the adsorption effect, zeolite is added to 22.5 to 27.5 per 100 parts by weight of Otani stone powder. In the present invention, it is necessary to mix in parts by weight. Such zeolite is not particularly limited, and may be obtained by pulverizing general zeolite. For reference, the components of the zeolite used in the experiment are water (N: 4.18%), pH (dry matter equivalent 1:10, 21 ° C .: 7.2), hereinafter, dry matter equivalent value, phosphoric acid Total amount (P 2 O 5 : 0.03%), total amount of potassium (K 2 O: 2.12%), total amount of lime (CaO: 2.06%), total amount of bitter earth (MgO: 0.55%), silica Total amount of acid (SiO 2 : 71.66%), iron oxide (Fe 2 O 3 : 1.66%), aluminum oxide (Al 2 O 3 : 11.61%), sodium oxide (Na 2 O: 2.22) %) And cation exchange amount (166 meq / 100 g of dry matter). It is desirable to make the particle sizes of Otani stone powder and zeolite as uniform as possible, and it is conceivable to obtain them with a general grinder such as a ball mill (tube mill).

角また粉は、紅藻類スギノリ目の海藻糊であり、水分7.0%以下、粒度32メッシュ・100%パス、保水率65%以上75%以下のものを用い、これを大谷石粉100重量部に対して、5.7〜6.6重量部の範囲内に含有することが本発明では必要である。   The horn or powder is a seaweed paste of red seaweeds, which has a water content of 7.0% or less, a particle size of 32 mesh, 100% pass, and a water retention rate of 65% or more and 75% or less. On the other hand, it is necessary in the present invention to contain it in the range of 5.7 to 6.6 parts by weight.

硅砂は、7号のものを用い、大谷石粉100重量部に対して、45〜55重量部の範囲内に含有することが本発明では必要である。   In the present invention, cinnabar sand is used for No. 7 and contained in a range of 45 to 55 parts by weight with respect to 100 parts by weight of Otani stone powder.
