Abstract
Description
本発明は、建築物における内装仕上材として好適な積層体に関するものである。 The present invention relates to a laminate suitable as an interior finishing material in a building.
近年、快適な居住空間に対する関心が高まっている。これに関し、壁、天井等の内装面の表面仕上げにおいては、結露防止やカビ発生防止、あるいは湿度の調整による不快感抑制、等の機能を有する調湿性仕上材への期待が高まっている。
例えば、特許文献１（特開２００１−１８３１２号公報）には、通気性を有する不織布と覆材との間に備長炭粒子を固定化した調湿シートが開示されている。また、特許文献２（特開２００３−１５５７８６号公報）には、吸放湿性材料と水硬性物質とを含む吸放湿性基材の少なくとも一面に、吸放湿性材料粒粉が添加された塗料による塗膜層が形成されてなる吸放湿性建材が開示されている。
In recent years, interest in comfortable living spaces has increased. In this regard, in the surface finishing of interior surfaces such as walls and ceilings, there is an increasing expectation for a humidity control finishing material having functions such as prevention of condensation, prevention of mold generation, and suppression of discomfort by adjusting humidity.
For example, Patent Document 1 (Japanese Patent Laid-Open No. 2001-18312) discloses a humidity control sheet in which Bincho charcoal particles are fixed between a breathable nonwoven fabric and a covering material. Patent Document 2 (Japanese Patent Application Laid-Open No. 2003-155786) discloses a paint in which moisture absorbing / releasing material particles are added to at least one surface of a moisture absorbing / releasing material containing a moisture absorbing / releasing material and a hydraulic substance. A hygroscopic building material in which a coating layer is formed is disclosed.
ところで、近年、室内環境においてはシックハウス問題等が社会的にクローズアップされている状況であり、各種有害ガスの拡散防止が求められている。このような有害ガスとしては、例えば、ホルムアルデヒド、アンモニア、硫化水素、メチルメルカプタン、トリメチルアミン等が挙げられる。上述の特許文献では、木炭、珪藻土、シリカゲル、ゼオライト、アロフェン等の吸放湿性材料が使用されている。このような吸放湿性材料は、有害ガスの吸着性能をある程度有することも知られており、室内環境の改善に有効な成分として期待できる。
しかしながら、上述の特許文献に記載の内装仕上材では、吸放湿性材料の吸着性能が飽和状態に達すると、それ以上有害ガスを吸着することはできず、吸着効果に限界がある。また、一旦吸着された有害ガスが、再度室内空間へ放出されるおそれもある。このような有害ガスの再放出は、室内環境向上の妨げとなる。
By the way, in recent years, in the indoor environment, the sick house problem and the like have been socially raised, and prevention of diffusion of various harmful gases is demanded. Examples of such harmful gases include formaldehyde, ammonia, hydrogen sulfide, methyl mercaptan, trimethylamine and the like. In the above-mentioned patent documents, moisture absorbing / releasing materials such as charcoal, diatomaceous earth, silica gel, zeolite, and allophane are used. Such moisture-absorbing / releasing materials are also known to have a certain level of harmful gas adsorption performance and can be expected as effective components for improving the indoor environment.
However, in the interior finishing material described in the above-mentioned patent document, when the adsorption performance of the hygroscopic material reaches a saturated state, no more harmful gas can be adsorbed, and the adsorption effect is limited. Moreover, the harmful gas once adsorbed may be released into the indoor space again. Such re-release of the harmful gas hinders improvement of the indoor environment.
このような問題に加え、上述の特許文献に記載の如き内装仕上材の表面は、一般に、水分を吸収しやすい性質を有している。そのため、仕上材表面に水分が付着すると、早期に表面から内部へ水分が吸収拡散される。水分中に水溶性成分や分散成分等が含まれる場合は、これらの成分も仕上材内部に吸収拡散される。さらに、水分中の物質が変色性や着色性を有する場合は、水分が付着した部分の変色や、染みの発生が問題となる。
これに対し、吸放湿性基材の上にクリヤー塗料を塗装する方法があるが、この方法では、吸放湿性基材の質感が損われたり、吸放湿性が阻害されたり、あるいは塗膜の膨れが発生しやすくなる等の問題が生じる。
特許文献３では、吸放湿性基材に対して適用可能な上塗塗料が記載されている。しかしながら、該公報に記載の上塗塗料は、クレーや炭酸カルシウム等の体質顔料を多量に含むため、吸放湿性基材の色彩を隠ぺいし、意匠性を低下させるものである。また、形成された塗膜は、水分を吸収しやすく、塗膜変色を引き起こすおそれもある。
In addition to such problems, the surface of the interior finishing material as described in the above-mentioned patent document generally has a property of easily absorbing moisture. Therefore, when moisture adheres to the surface of the finishing material, moisture is absorbed and diffused from the surface to the inside at an early stage. When water-soluble components, dispersed components, and the like are contained in moisture, these components are also absorbed and diffused into the finish material. Furthermore, when a substance in water has discoloration or coloration, discoloration of a portion to which water has adhered or generation of a stain becomes a problem.
On the other hand, there is a method in which a clear paint is applied on a moisture absorbing / releasing substrate, but this method impairs the texture of the moisture absorbing / releasing substrate, impairs moisture absorbing / releasing properties, Problems such as bulging are likely to occur.
Patent Document 3 describes a top coating that can be applied to a hygroscopic substrate. However, since the top coating described in the publication contains a large amount of extender pigments such as clay and calcium carbonate, it conceals the color of the moisture-absorbing / releasing substrate and lowers the design. Further, the formed coating film easily absorbs moisture and may cause discoloration of the coating film.

このような吸放湿性粉粒体は、温度２０℃・相対湿度９０％における吸湿率が、通常１０％以上、好ましくは２０％以上の性能を有するものである。なお、温度２０℃・相対湿度９０％における吸湿率とは、試料を温度２０℃・相対湿度４５％の恒温恒湿器にて２４時間乾燥した後、温度２０℃・相対湿度９０％の恒温恒湿器にて２４時間吸湿させたときの重量変化より求められる値である。すなわち、
吸湿率（％）＝｛（吸湿後の重量−乾燥後の重量）／乾燥後の重量｝×１００
Such hygroscopic particles have a performance of a moisture absorption rate of 10% or more, preferably 20% or more at a temperature of 20 ° C. and a relative humidity of 90%. The moisture absorption rate at a temperature of 20 ° C. and a relative humidity of 90% is a constant temperature and constant temperature of 20 ° C. and a relative humidity of 90% after the sample is dried for 24 hours in a constant temperature and humidity chamber of a temperature of 20 ° C. and a relative humidity of 45%. It is a value obtained from a change in weight when moisture is absorbed in a humidifier for 24 hours. That is,
Moisture absorption rate (%) = {(weight after moisture absorption−weight after drying) / weight after drying} × 100
吸放湿性粉粒体の構成比率は、結合剤１００重量部（固形分）に対し、通常２０〜２０００重量部、好ましくは１００〜１５００重量部、より好ましくは２００〜１０００重量部とする。吸放湿性粉粒体の構成比率が小さすぎる場合は、十分な調湿性能を得ることが困難となる。また、防火性の点においても不利となる。吸放湿性粉粒体の構成比率が大きすぎる場合は、積層体の強度や可撓性が不十分となる。 The constituent ratio of the hygroscopic powder is usually 20 to 2000 parts by weight, preferably 100 to 1500 parts by weight, and more preferably 200 to 1000 parts by weight with respect to 100 parts by weight (solid content) of the binder. When the constituent ratio of the hygroscopic powder is too small, it becomes difficult to obtain sufficient humidity control performance. It is also disadvantageous in terms of fire resistance. When the constituent ratio of the hygroscopic powder is too large, the strength and flexibility of the laminate are insufficient.
さらに、吸放湿層においては骨材を含むこともできる。骨材の平均粒子径は、通常０．０１〜５ｍｍ、好ましくは０．０５〜２ｍｍ、より好ましくは０．１〜１ｍｍのものが好適である。このような骨材を使用することにより、調湿性能をいっそう高めることができる。また、吸放湿層の厚膜化を図ることもできる。なお、骨材の平均粒子径は、ＪＩＳ Ｚ８８０１−１：２０００に規定される金属製網ふるいを用いてふるい分けを行い、その重量分布の平均値を算出することによって得られる値である。
骨材の種類は特に限定されず、天然品、人工品のいずれも使用することができる。具体的には、例えば、重質炭酸カルシウム、寒水石、カオリン、クレー、陶土、チャイナクレー、タルク、水酸化アルミニウム、水酸化マグネシウム、バライト粉、珪砂、砂利、ガラスビーズ、樹脂ビーズ、金属粒、あるいは岩石、ガラス、陶磁器、焼結体、コンクリート、モルタル、プラスチック、ゴム、貝殻等の破砕品等が挙げられる。これらに着色を施したものも使用することができる。
Further, the moisture absorbing / releasing layer may contain aggregate. The average particle diameter of the aggregate is usually 0.01 to 5 mm, preferably 0.05 to 2 mm, more preferably 0.1 to 1 mm. By using such an aggregate, the humidity control performance can be further enhanced. In addition, the moisture absorption / release layer can be made thicker. In addition, the average particle diameter of aggregate is a value obtained by performing sieving using a metal net sieve specified in JIS Z8801-1: 2000 and calculating the average value of the weight distribution.
The type of aggregate is not particularly limited, and any of natural products and artificial products can be used. Specifically, for example, heavy calcium carbonate, cold water stone, kaolin, clay, porcelain clay, china clay, talc, aluminum hydroxide, magnesium hydroxide, barite powder, quartz sand, gravel, glass beads, resin beads, metal particles, Alternatively, crushed products such as rocks, glass, ceramics, sintered bodies, concrete, mortar, plastic, rubber, and shells can be used. Colored ones can also be used.
骨材の構成比率は、結合剤１００重量部（固形分）に対し、通常５０〜２５００重量部、好ましくは１００〜２０００重量部、より好ましくは３００〜１５００重量部とする。骨材比率が小さすぎる場合は、調湿性能の向上効果が得られない。骨材比率が大きすぎる場合は、骨材が脱離しやすくなる。また、可撓性を付与することが困難となる。なお、本発明における骨材の温度２０℃・相対湿度９０％における吸湿率は、通常１０％未満、好ましくは３％以下である。 The composition ratio of the aggregate is usually 50 to 2500 parts by weight, preferably 100 to 2000 parts by weight, and more preferably 300 to 1500 parts by weight with respect to 100 parts by weight (solid content) of the binder. When the aggregate ratio is too small, the effect of improving the humidity control performance cannot be obtained. When the aggregate ratio is too large, the aggregate is easily detached. Moreover, it becomes difficult to impart flexibility. In the present invention, the moisture absorption rate of the aggregate at a temperature of 20 ° C. and a relative humidity of 90% is usually less than 10%, preferably 3% or less.
吸放湿層には、上述の成分以外に、例えば、顔料、繊維、可塑剤、抗菌剤、防黴剤、防虫剤、難燃剤、架橋剤、滑剤、造膜助剤、酸化防止剤、紫外線吸収剤等が含まれていてもよい。 In addition to the above-mentioned components, for example, pigments, fibers, plasticizers, antibacterial agents, insecticides, insecticides, flame retardants, crosslinking agents, lubricants, film-forming aids, antioxidants, ultraviolet rays An absorbent or the like may be included.

The average particle size of such a photocatalytic substance is usually about 0.001 to 1 μm (preferably 0.01 to 0.5 μm).
In addition, it is better not to use a photocatalyst substance that has a photocatalyst substance supported on a hygroscopic particulate material because the photocatalytic action may be inhibited by moisture absorption.
透湿層において、光触媒物質を使用せずに化学物質吸着剤のみを使用した場合は、有害ガスの吸着量に限界が生じ、吸着能を超える効果を期待することができない。
逆に、光触媒物質のみを使用した場合、有害ガスの分解効果を得るには、光触媒物質の構成比率を十分に増やして、有害ガスが光触媒物質に接触する確率を高めなければならない。しかし、光触媒物質を増量すると、結合剤の早期劣化を招いてしまう。また、透湿層の色彩が制限される、あるいはコスト高となる等の問題が生じる。すなわち、光触媒増量には実用上限界がある。
本発明では、化学物質吸着剤と光触媒物質を併用することによって、有害ガスの吸着・分解・再放出防止において実用的な性能を得ることができ、透湿層の有害ガスフィルター効果を十分に発揮させることができる。
When only the chemical substance adsorbent is used in the moisture-permeable layer without using the photocatalytic substance, the amount of harmful gas adsorbed is limited, and an effect exceeding the adsorption capacity cannot be expected.
On the contrary, when only the photocatalytic substance is used, in order to obtain the decomposition effect of the harmful gas, the constituent ratio of the photocatalytic substance must be increased sufficiently to increase the probability that the harmful gas contacts the photocatalytic substance. However, when the amount of the photocatalytic substance is increased, the binder is prematurely deteriorated. Further, there arises a problem that the color of the moisture permeable layer is limited or the cost is increased. That is, there is a practical limit to the increase in photocatalyst.
In the present invention, by using a chemical adsorbent and a photocatalytic substance in combination, practical performance can be obtained in the adsorption, decomposition, and re-release prevention of harmful gases, and the harmful gas filter effect of the moisture permeable layer can be sufficiently exhibited. Can be made.
本発明積層体における透湿層としては、結合剤、平均粒子径０．０１〜５ｍｍの骨材、化学物質吸着剤、及び光触媒物質を必須成分とするものが好適である。このような透湿層を採用することにより、有害ガスの吸着・分解効果、再放出抑制効果をいっそう高めることができる。 As the moisture permeable layer in the laminate of the present invention, those having a binder, an aggregate having an average particle diameter of 0.01 to 5 mm, a chemical substance adsorbent, and a photocatalytic substance as essential components are suitable. By adopting such a moisture permeable layer, it is possible to further enhance the adsorption / decomposition effect of harmful gas and the effect of suppressing re-release.
透湿層における結合剤としては、透明被膜が形成可能な有機質樹脂が好適である。有機質樹脂としては、吸放湿層と同様のものが使用できる。透湿層における有機質樹脂が架橋反応性を有する場合は、透湿性、耐水性、耐薬品性等の点で有利であり、光触媒物質に対する抵抗性を高めることもできる。
透湿層における有機質樹脂として水分散性樹脂を使用する場合、その平均粒子径は、通常５０μｍを超え（好ましくは８０μｍ超、より好ましくは１００μｍ超）、かつ５００μｍ未満（好ましくは４００μｍ未満、より好ましくは３００μｍ未満）であることが望ましい。平均粒子径がこのような範囲内であれば、適度な透湿性能を得ることが可能となる。
透湿層における有機質樹脂のガラス転移温度は、通常−３０〜１２０℃、好ましくは−１０〜１００℃、より好ましくは０〜８０℃である。ガラス転移温度がこのような範囲内であれば、積層体に適度な可撓性を付与することができ、積層体表面の汚染物質付着防止の点でも好適である。
さらに、透湿層における有機質樹脂のガラス転移温度は、吸放湿層における有機質樹脂のガラス転移温度よりも高く（好ましくは５℃以上高く、より好ましくは１０℃以上高く）設定することが望ましい。このようなガラス転移温度の設定により、切断等の加工が容易となり、施工現場の状況に応じて積層体を自由に加工することが可能となる。具体的には、吸放湿層における有機質樹脂のガラス転移温度が−２０〜８０℃、透湿層における有機質樹脂のガラス転移温度が−１０〜１００℃であり、かつ透湿層における有機質樹脂のガラス転移温度が、吸放湿層における有機質樹脂のガラス転移温度よりも５℃以上高くなるように設定することが望ましい。
As the binder in the moisture permeable layer, an organic resin capable of forming a transparent film is suitable. As the organic resin, those similar to the moisture absorbing / releasing layer can be used. When the organic resin in the moisture permeable layer has cross-linking reactivity, it is advantageous in terms of moisture permeability, water resistance, chemical resistance, etc., and the resistance to the photocatalytic substance can be increased.
When a water dispersible resin is used as the organic resin in the moisture permeable layer, the average particle diameter is usually more than 50 μm (preferably more than 80 μm, more preferably more than 100 μm) and less than 500 μm (preferably less than 400 μm, more preferably Is less than 300 μm). When the average particle diameter is within such a range, it is possible to obtain an appropriate moisture permeability.
The glass transition temperature of the organic resin in the moisture permeable layer is usually −30 to 120 ° C., preferably −10 to 100 ° C., more preferably 0 to 80 ° C. If the glass transition temperature is within such a range, moderate flexibility can be imparted to the laminate, which is also preferable from the viewpoint of preventing the adhesion of contaminants on the laminate surface.
Furthermore, it is desirable to set the glass transition temperature of the organic resin in the moisture permeable layer to be higher (preferably higher than 5 ° C., more preferably higher than 10 ° C.) than the glass transition temperature of the organic resin in the moisture absorbing / releasing layer. By such setting of the glass transition temperature, processing such as cutting is facilitated, and the laminate can be processed freely according to the situation at the construction site. Specifically, the glass transition temperature of the organic resin in the moisture absorbing / releasing layer is -20 to 80 ° C, the glass transition temperature of the organic resin in the moisture permeable layer is -10 to 100 ° C, and the organic resin in the moisture permeable layer is It is desirable to set the glass transition temperature to be 5 ° C. or more higher than the glass transition temperature of the organic resin in the moisture absorption / release layer.
透湿層における骨材としては、平均粒子径が０．０１〜５ｍｍ、好ましくは０．０５〜２ｍｍ、より好ましくは０．１〜１ｍｍのものを使用する。骨材の粒子径が小さすぎる場合は、透湿性能が低下し、下層の吸放湿性能を阻害することとなる。また、仕上り外観が単調な色彩となってしまう。さらに、透湿層内部の光触媒成分に光が届きにくくなり、有害ガス分解効果の点で不利となる。粒子径が大きすぎる場合は、表面凹凸が大きくなりすぎ、均一な厚みの層を得ることが困難となる。骨材の種類については、吸放湿層の骨材と同様のものが使用可能である。
透湿層における骨材の構成比率は、結合剤１００重量部（固形分）に対し、通常１００〜４０００重量部、好ましくは３００〜３０００重量部、より好ましくは５００〜２０００重量部とする。骨材比率が小さすぎる場合は、有害ガスの吸着・分解効果が不十分となり、下層の吸放湿性能を阻害するおそれもある。また、透湿層の厚膜化が困難となり、意匠性付与の点で不利となる。骨材比率が大きすぎる場合は、骨材が脱離しやすくなる。
As the aggregate in the moisture permeable layer, one having an average particle diameter of 0.01 to 5 mm, preferably 0.05 to 2 mm, more preferably 0.1 to 1 mm is used. When the particle diameter of the aggregate is too small, the moisture permeability performance is lowered and the moisture absorption / release performance of the lower layer is inhibited. In addition, the finished appearance becomes a monotonous color. Furthermore, it becomes difficult for light to reach the photocatalyst component inside the moisture-permeable layer, which is disadvantageous in terms of harmful gas decomposition effect. When the particle diameter is too large, the surface unevenness becomes too large, and it becomes difficult to obtain a layer having a uniform thickness. About the kind of aggregate, the thing similar to the aggregate of a moisture absorption / release layer can be used.
The composition ratio of the aggregate in the moisture permeable layer is usually 100 to 4000 parts by weight, preferably 300 to 3000 parts by weight, and more preferably 500 to 2000 parts by weight with respect to 100 parts by weight (solid content) of the binder. When the aggregate ratio is too small, the effect of adsorbing and decomposing noxious gas becomes insufficient, and the moisture absorption / release performance of the lower layer may be hindered. Moreover, it becomes difficult to increase the thickness of the moisture permeable layer, which is disadvantageous in terms of imparting design properties. When the aggregate ratio is too large, the aggregate is easily detached.
化学物質吸着剤の構成比率は、結合剤１００重量部（固形分）に対し、通常０．１〜１００重量部、好ましくは１〜８０重量部、より好ましくは５〜５０重量部とする。化学物質吸着剤の構成比率が小さすぎる場合は、有害ガスの吸着効果、再放出防止効果が不十分となる。化学物質吸着剤の構成比率が大きすぎる場合は、表面意匠性や耐水性等に悪影響を与えるおそれがある。また、コスト面でも不利となる。 The component ratio of the chemical substance adsorbent is usually 0.1 to 100 parts by weight, preferably 1 to 80 parts by weight, and more preferably 5 to 50 parts by weight with respect to 100 parts by weight (solid content) of the binder. When the composition ratio of the chemical substance adsorbent is too small, the harmful gas adsorption effect and the re-release prevention effect are insufficient. If the composition ratio of the chemical substance adsorbent is too large, there is a risk of adversely affecting the surface design and water resistance. Further, it is disadvantageous in terms of cost.
光触媒物質の構成比率は、結合剤１００重量部（固形分）に対し、通常０．１〜５０重量部、好ましくは０．５〜３０重量部、より好ましくは１〜２０重量部とする。光触媒物質の構成比率が小さすぎる場合は、有害ガスの分解効果、再放出防止効果が不十分となる。光触媒物質の構成比率が大きすぎる場合は、結合剤の早期劣化を招いてしまう。また、透湿層の色彩が制限されやすくなる。 The composition ratio of the photocatalytic substance is usually 0.1 to 50 parts by weight, preferably 0.5 to 30 parts by weight, and more preferably 1 to 20 parts by weight with respect to 100 parts by weight (solid content) of the binder. When the constituent ratio of the photocatalytic substance is too small, the harmful gas decomposition effect and the re-release prevention effect are insufficient. When the constituent ratio of the photocatalytic substance is too large, the binder is prematurely deteriorated. Moreover, it becomes easy to restrict | limit the color of a moisture-permeable layer.

If the moisture absorbing / releasing layer and the moisture permeable layer have such thicknesses, the effects of the present invention are sufficiently obtained. Moreover, various uneven | corrugated patterns can also be formed in the surface of a laminated body. Furthermore, there is an advantage that the laminate can be manufactured without using a metal-based, inorganic-based, or wood-based substrate. If the thickness of the moisture absorbing / releasing layer or moisture permeable layer is smaller than the above range, it will be difficult to obtain sufficient performance in the humidity control function, toxic gas adsorption / decomposition / re-release control function, etc. The use of a substrate is indispensable.
上塗層は透湿層の表面を被覆した状態であればよく、その一部が透湿層に含浸していてもよい。上塗層は、通常０．０１〜０．５ｋｇ／ｍ２程度の塗付量で形成すればよい。 The top coat layer may be in a state where the surface of the moisture permeable layer is covered, and part of the moisture permeable layer may be impregnated. The top coat layer may be formed usually with a coating amount of about 0.01 to 0.5 kg / m 2 .
