【発明の属する技術分野】
本発明は樹脂組成物とそれを一部に含む建材に関し、特に、静止状態でマイナスイオンを発生する樹脂組成物とそれを一部に含む建材に関する。
【０００２】
【従来の技術】
近年、マイナス電荷を有するイオンが人体に有益であることが検証されつつあり、種々のマイナスイオン発生器機、例えば、人工的に電圧の放電によってマイナス空気イオンを発生させるようにした装置が提案されている。素材そのものがマイナスイオンを放出する物質としてトルマリン（電気石）も知られている。
【０００３】
【発明が解決しようとする課題】
電気を与えることでマイナスイオンを発生させるようにした装置は、装置自体が高価であることに加え、活性酸素の人体への懸念が取りざたされているオゾンも同時発生しており、また、臭いも発生されてしまう欠点がある。トルマリン（電気石）は静止状態でマイナスイオンを放出するとはいえ、本発明者らの実験では、静止状態での発生量はきわめて少なく、実効性に乏しいことがわかった。そのために、内装材や外装材のような建材、例えば、木質系の化粧板、天井材、壁面材、床材のように静止状態に置かれる建材を製造しまた施工する際に、トルマリンを混入した塗料や接着剤、目止め剤などを用いるようにしても、マイナスイオンの持つ人体への有益性を該建材に期待することはできない。
本発明は上記のような事情に鑑みてなされたものであり、静止状態であっても実効性を奏することのできる量のマイナスイオンを発生する剤を提供すること、および、該剤を含む建材を提供することを目的とする。
【０００４】
【課題を解決するための手段】
本発明者らは、上記の課題の解決に向けて、静止状態で多くのマイナスイオンを放出する物質について種々の検討を重ねた結果、希土類元素を含む鉱物はその目的に合致する物質であり、その粉砕物あるいは粉砕物を１０００℃〜１８００℃の降温度で焼成したセラミックスのみを樹脂に混入するだけで、所要のマイナスイオンを放出する樹脂組成物が得られることを知見した。本発明はその知見に基づいており、本発明による樹脂組成物は、樹脂に粒子径が２００μｍ以下の希土類元素を含む鉱物粉体または該鉱物粉体を焼成したセラミックスを混入したマイナスイオンを放出する樹脂組成物であることを特徴とする。
【０００５】
本発明において、希土類元素を含む鉱物としては、フェルグソン石、モナズ石、バストネス石、ゼノタイム、コルンブ石、ベタホ石、サマルスキー石、ユークセン石、ユークセン石、タンタル石、閃ウラン石、方トリム石、ゴム石、カルノー石、ガドリン石などがある。これらの鉱物は樹脂との混合性を良好にするために粒子径２００μｍ以下の粉砕物（粉体）とされる。これより大きいと、混合が不均一となり好ましくない。より好ましくは３０μｍ以下に粉砕したものを用いる。この場合には、樹脂組成物を塗料や接着剤として使用するときに、塗布状態で表面が平滑となる利点がある。
【０００６】
樹脂に対する希土類元素を含む鉱物粉体または該鉱物粉体を焼成したセラミックスの混入量は、樹脂１００に対して１０〜３重量％であることが望ましい。１０重量％より多いと被爆の問題があり、３重量％以下では実効性がある量のマイナスイオンが発生しない。
【０００７】
本発明において、使用する樹脂の種類に特に制限はなく、当該樹脂組成物をどのような目的で使用するかに応じて、適宜の樹脂が選択される。例えば、樹脂組成物が塗料である場合には、ラッカー系、ポリエステル樹脂系、アミノアルキッド樹脂系、ポリウレタン樹脂系などの樹脂である。樹脂組成物が接着剤である場合には、ユリア樹脂接着剤、フェノール樹脂接着剤、レゾルシノール樹脂接着剤、酢酸ビニル樹脂エマルジョン接着剤などの樹脂である。樹脂組成物が目止め剤の場合には、ラッカー系、ポリウレタン樹脂系などの樹脂である。その他、樹脂含浸紙を製造する場合に、紙に含浸する樹脂に混入してもよく、樹脂を主成分とする印刷インキや転写インキなどに含浸してもよい。上記鉱物粉体または該鉱物粉体を焼成したセラミックスを上記の樹脂へ混入するには、一般的な攪拌機を用いればよい。いずれの場合にも、本発明による樹脂組成物は、従来適宜の目的で使用されていた樹脂に単に上記の粉砕物あるいは粉砕物を１０００℃〜１８００℃の降温度で焼成したセラミックスを単に所要量だけ混入するのみであり、調製はきわめて容易である。
【０００８】
本発明は、上記の樹脂組成物を何らかの状態で含んでいる建材をも開示する。本発明による建材は、そこに含まれる樹脂組成物が静止状態で多くのマイナスイオンを放出するものであることから、健康によく、抗菌作用もあり、防臭効果もある建材が得られる。建材としては、▲１▼適宜の基材の表面に塗料として本発明による樹脂組成物を塗布したもの、▲２▼基材の表面に適宜の表面化粧材を本発明による樹脂組成物を接着剤として用いて貼着したもの、▲３▼木質系素材を本発明による樹脂組成物を接着剤として用いて接着一体化したものなどを例として挙げることができる。
【０００９】
前記▲１▼の場合、「適宜の基材」に制限はなく、従来、化粧板、天井材、壁面材、床材のような建材のための基材として用いられているものを任意に用いればよい。例えば、合板、あるいは、パーティクルボード（ＰＢ）、中質繊維板（ＭＤＦ）、配向性繊維板木質系基材（ＯＳＢ）などの木質繊維板、無垢の木板、セメント板、軽量化セメント板、金属板、樹脂板など任意である。
前記▲２▼の場合、「基材」としては上記▲１▼に記載したような任意の基材であってよく、「表面化粧材」としては、従来、化粧板、天井材、壁面材、床材のような建材のための表面化粧材として用いられているものを任意に用いることができる。例えば、紙、樹脂シート、突板などを挙げることができる。
前記▲３▼の場合、「木質系素材」としては、積層合板の素材である単板、集成材の素材である木片、上記木質繊維板の素材である木質チップや木片のようなものが挙げられる。
【００１０】
【実施例】
希土類元素を含む鉱物のセラミックス粉末を、水性塗料に重量比１００：７．５％添加し、充分に混合した。得られた塗料を１２ｍｍ厚の突板貼り合板（Ｆｃ０タイプ）にロールコーターにて５．６〜１０ｇ／尺2の範囲で塗布して４種類のサンプル化粧板を作成した。各サンプルについてそれぞれ５個を用意し、放射線とイオン感知式測定機で化粧板から発生するマイナスイオンの個数Ｎ／ｃｃを測定した。その結果を表１に示す。
【００１１】
【表１】
なお、平均は最小値と最大値を除いた値から算出した。
各サンプルからのマイナスイオン発生量は、トルマリンが静止状態で発生するマイナスイオンの個数（ほぼ０）と比較して格段に大きく、実効性のあるマイナスイオン量である。
【００１３】
【発明の効果】
本発明によれば、樹脂に適量の希土類元素を含む鉱物粉体または該鉱物粉体を焼成したセラミックスを混入したマイナスイオンを混入するのみで、実効性のある量のマイナスイオンを放出する樹脂組成物が得られる。その樹脂組成物を塗料や接着剤として用いた建材あるいは目止め剤として用いた建築物は、そのままの状態で、すなわち静止状態で実効性を奏する量のマイナスイオンを発生することから、健康によく、抗菌作用もあり、防臭効果もある建材あるいは建築物が得られる。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a resin composition and a building material partially including the resin composition, and more particularly to a resin composition that generates negative ions in a stationary state and a building material including the resin composition.
[0002]
[Prior art]
In recent years, it has been verified that negatively charged ions are beneficial to the human body, and various negative ion generators, for example, devices that artificially generate negative air ions by discharging a voltage have been proposed. Yes. Tourmaline is also known as a material that emits negative ions.
[0003]
[Problems to be solved by the invention]
The device that generates negative ions by supplying electricity is not only expensive, but also generates ozone that raises concerns about active oxygen in the human body. There is a fault that is generated. Although tourmaline (tourmaline) emits negative ions in a stationary state, in our experiments, it was found that the amount generated in a stationary state is very small and its effectiveness is poor. To that end, building materials such as interior materials and exterior materials, for example, wooden decorative panels, ceiling materials, wall materials, floor materials, and other construction materials that are placed in a stationary state are mixed with tourmaline. Even if a paint, an adhesive, a sealant, or the like is used, the building material cannot be expected to be beneficial to the human body.
The present invention has been made in view of the above circumstances, and provides an agent that generates an anion of negative ions that can be effective even in a stationary state, and a building material containing the agent The purpose is to provide.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the present inventors have conducted various studies on a substance that releases many negative ions in a stationary state, and as a result, a mineral containing a rare earth element is a substance that meets its purpose, It has been found that a resin composition capable of releasing required negative ions can be obtained by mixing only the ceramics obtained by firing the pulverized product or the pulverized product at a temperature drop of 1000 ° C. to 1800 ° C. into the resin. The present invention is based on the knowledge, and the resin composition according to the present invention releases negative ions in which a mineral powder containing rare earth elements having a particle diameter of 200 μm or less or ceramics obtained by firing the mineral powder is mixed in the resin. It is a resin composition.
[0005]
In the present invention, the rare earth element-containing mineral includes fergusonite, monazite, bustness stone, xenotime, columbite, betajolite, samarsky stone, eucsenite, eucsenite, tantalum stone, uraniumite, calcite, rubber There are stones, carnot stones, and gadolin stones. These minerals are made into a pulverized product (powder) having a particle size of 200 μm or less in order to improve the mixing property with the resin. If it is larger than this range, the mixing becomes uneven, which is not preferable. More preferably, those pulverized to 30 μm or less are used. In this case, when the resin composition is used as a paint or an adhesive, there is an advantage that the surface becomes smooth in the applied state.
[0006]
The mixing amount of the mineral powder containing the rare earth element relative to the resin or the ceramics obtained by firing the mineral powder is preferably 10 to 3% by weight with respect to the resin 100. If it is more than 10% by weight, there is a problem of exposure, and if it is 3% by weight or less, an effective amount of negative ions is not generated.
[0007]
In the present invention, the type of resin to be used is not particularly limited, and an appropriate resin is selected depending on the purpose for which the resin composition is used. For example, when the resin composition is a paint, it is a resin such as a lacquer system, a polyester resin system, an amino alkyd resin system, and a polyurethane resin system. When the resin composition is an adhesive, it is a resin such as a urea resin adhesive, a phenol resin adhesive, a resorcinol resin adhesive, or a vinyl acetate resin emulsion adhesive. When the resin composition is a sealing agent, it is a resin such as a lacquer or polyurethane resin. In addition, when manufacturing a resin-impregnated paper, it may be mixed in a resin impregnated in the paper, or may be impregnated in a printing ink or a transfer ink containing the resin as a main component. A general stirrer may be used to mix the mineral powder or ceramics obtained by firing the mineral powder into the resin. In any case, the resin composition according to the present invention is simply a required amount of ceramics obtained by simply firing the above pulverized product or pulverized product at a falling temperature of 1000 ° C. to 1800 ° C. on a resin that has been used for an appropriate purpose. It is very easy to prepare.
[0008]
The present invention also discloses a building material containing the above resin composition in any state. Since the building material according to the present invention releases many negative ions in a stationary state, the building material is good for health, has an antibacterial action, and has a deodorizing effect. As building materials, (1) a resin composition according to the present invention is applied as a paint on the surface of an appropriate base material, and (2) an appropriate surface decorative material is applied to the surface of the base material with a resin composition according to the present invention as an adhesive. Examples thereof include (3) affixed and used, and (3) a woody material bonded and integrated using the resin composition according to the present invention as an adhesive.
[0009]
In the case of {circle around (1)}, there is no restriction on “appropriate base material”, and any material conventionally used as a base material for building materials such as decorative panels, ceiling materials, wall materials, floor materials can be used arbitrarily. That's fine. For example, plywood, or wood fiber board such as particle board (PB), medium fiber board (MDF), oriented fiber board, wood base material (OSB), solid wood board, cement board, lightweight cement board, metal A board, a resin board, etc. are arbitrary.
In the case of (2), the “base material” may be any base material as described in (1) above, and as the “surface decorative material”, conventionally, a decorative board, a ceiling material, a wall surface material, What is used as a surface decoration material for building materials like a flooring can be used arbitrarily. For example, paper, a resin sheet, a veneer, etc. can be mentioned.
In the case of (3), examples of the “woody material” include a veneer that is a material of laminated plywood, a piece of wood that is a material of laminated wood, and a wood chip or piece of wood that is a material of the above-mentioned wood fiberboard. It is done.
[0010]
【Example】
A mineral ceramic powder containing a rare earth element was added to a water-based paint at a weight ratio of 100: 7.5% and mixed well. The obtained paint was applied to a 12 mm thick veneer laminated board (Fc0 type) with a roll coater in the range of 5.6 to 10 g / scale 2 to prepare four types of sample decorative boards. Five samples were prepared for each sample, and the number N / cc of negative ions generated from the decorative plate was measured with a radiation and ion-sensing measuring machine. The results are shown in Table 1.
[0011]
[Table 1]
The average was calculated from the value excluding the minimum and maximum values.
The amount of negative ions generated from each sample is a significantly large negative ion amount that is much larger than the number of negative ions (approximately 0) generated in a stationary state of tourmaline.
[0013]
【The invention's effect】
According to the present invention, a resin composition that releases an effective amount of negative ions only by mixing a mineral powder containing an appropriate amount of a rare earth element or a ceramic obtained by firing the mineral powder into the resin. Things are obtained. Building materials that use the resin composition as paints or adhesives or buildings that use them as sealants generate negative ions in an amount that is effective in the rest state, that is, in a stationary state. A building material or building having antibacterial action and deodorizing effect can be obtained.
